Description

Incinerator Sealing System {INCINERATOR SEALS}

U.S. Pat. Demonstrate how to control properly. The first and third of these patents show incineration methods and equipment that optimize heat recovery for economical use and significantly improve the incineration efficiency of various wastes. These two patents set up three combustion zones to measure temperatures at critical locations and to change the combustion conditions to obtain the desired efficiency and environmental assessment. In addition, these patents achieve the object by using large-scale waste that does not require separate treatment before entering the combustion chamber. The system demonstrates the versatility to achieve environmentally normal incineration while treating significantly different types of waste.

The principles of these patents can be applied to a wide range of applications that do not require waste as fuel. This finding has also been found to be useful for the combustion of hydrocarbon-containing smoke from common, unidentified sources. According to these patents, such smoke can be burned, especially in systems without a combustion chamber.

However, even when the combustion chamber is used, these patents have improved the combustion chamber of the incinerator system. As an improvement, the bottom of the first furnace was stepped, and an air nozzle was arranged on the vertical surface of the staircase. Another consideration is that the combustion chamber of the incinerator contains a certain amount of oxygen as the combustion component, and the bottom and volume of the combustion chamber each have a general relationship to the heat content of the combustion waste. In addition, the speed of air entering the combustion chamber is limited to prevent the floating of unburned waste particles. Meanwhile, combustion chamber walls of various sizes have a specific relationship to each other for improved combustion.

The second and fourth of the above listed patents show how to transport material lying on the floor in a combustion chamber. These patents show that the movement of the bottom of the furnace, which actually promotes the advancement of the material, is not sinusoidal. The movement of the bottom is very similar to the movement of shoveling snow etc. Pulsating and advancing materials, especially combustion waste, can accelerate and decelerate large quantities of waste, increasing combustion speed and efficiency.

Basic's first four patents set up a completely new system for waste incineration. These patents set out the basic conditions for the incineration of waste and showed how to facilitate the process by passing a large amount of waste through the main combustion chamber. With these established factors, Basic wanted to improve its already developed system. In the process, the system has been further improved compared to the conventional one in order to reliably handle various wastes. The registration of the last three patents of the aforementioned patents was the result of Basic's ongoing efforts.

Basic has improved a variety of incinerators. In particular, the introduction of the concept of dividing a reburn tunnel into two parallel reburn sections allows each section to perform the same function for smoke from a combustion chamber or the like. The control over the three T's for combustion is significantly improved because of the variability in the two small reburn sections.

In another aspect, the above patent has provided an "excitor" in the reburn tunnel. The exciter substantially reduces the cross-sectional area of the center of the tunnel where a large amount of gas is located and forces the gas to pass around it. The spacing between the gas molecules and the wall surface is shortened, and the spacing between the outer wall and the exciter wall surface is also shortened, and the three T controls are significantly improved by heat radiation. In addition to the exciter, the air entering the tunnel can be sprayed to control temperature and time, as well as to provide sufficient oxygen for complete combustion. Another feature of the exciter is to supply air to the reburn tunnel through the support of the exciter and to lower the thermal conductivity outside the exciter to limit heat generation. The patent also shows that a damper can be installed at the exit of the reburn tunnel to further control the time (one of three T's) in combustion.

U.S. Patent 5,209,169 has given a whole new character to the combustion chamber with the bottom of the furnace. In particular, a lattice was installed near the inlet of the combustion chamber above the furnace. Garbage with high B.T.U content or juicy waste is placed on the grid. Juicy wastes are dried in the lattice, and for wastes with high B.T.U content, some of the volatile hydrocarbons are burned or discharged to prevent overheating and to prevent as much slag as possible from the bottom of the furnace. In either case, fixed hydrocarbon waste falls through the lattice into the combustion chamber. Wastes can fall with more than half combustible hydrocarbons. Meanwhile, the above-described object may be achieved by drilling holes of a predetermined size in the grid. Fluid such as air passing through the grating serves to cool the grating, and the refractory coating serves to protect the grating. Air can pass directly through the grid into the combustion chamber to increase combustion efficiency. Shaking the lattice may cause the waste to shake to achieve the desired combustion, and dry or partially burned waste may fall into the lower furnace.

U. S. Patent 5,413, 715 relates to a scoop for installing ash in an incinerator and then removing ash from the bucket. The scoop moves along the track and closes to hold the ash when it reaches the floor. After climbing up the track, the scoop opens and the ash falls to the back of a truck or the like.

As discussed above, waste combustion technology has been significantly advanced by Basic. As can be seen from the recent incineration tendency as described above, new improvements are made whenever the technology advances. Explaining this progress is as follows.

Summary of the Invention

Incinerators generally have a closed combustion chamber, with the exception of the waste inlet and the combustion product outlet. The combustion chamber has a floor and a wall to support the waste, and the wall is located on the floor and seals the surroundings like the floor. The wall surface together with the floor forms a substantially closed combustion chamber.

As described in John Basic, US Pat. No. 4,475,469, some kind of actuation means may be coupled to the bottom and walls of the incinerator. By this actuation means the floor is moved relative to the wall along a predetermined path. However, in some incinerators, the "floor" may follow a precise path. One such system uses a "rotary kiln" method. Rotary kilns simply rotate with the outer wall because they rotate along the correct path. The advantages of a basic system, in particular pulsed hearth, have been described in the aforementioned patents.

However, as described in US Pat. No. 4,475,469, the path the floor is moved by the actuation means can be significantly deflected in the desired path. This deflection is caused by a vibrating bag, which is less effective than other bags. Alternatively, the load of the furnace may be biased to one side. For these and other reasons, the actual vibrational motion can deviate significantly from normal operation. Deviation from the desired path places a significant burden on the incinerator, which must seal the gap through which the gas passes between the floor and the wall.

Thus, there is a need for an incinerator with sealing means coupled to the wall and the floor and running along at least a portion of the enclosed perimeter. In a part of the enclosed perimeter the sealing means must substantially prevent the passage of gas between the wall and the floor, especially when the floor is moved relative to the wall along the path by the actuating means. In particular, it is necessary to seal when the moving path of the floor is deflected in the predetermined path.

First, the sealing means may have a retaining means coupled to one of the bottom and the wall to contain the flowable non-gas material. Secondly, the sealing means may be provided with a immersion device coupled to the rest of the floor and the wall and partially immersed in the flowable material as the floor moves along a predetermined path.

On the other hand, the sealing means may comprise a flexible gas impermeable heat resistant film bonded to the bottom and the wall. In addition, the sealing means may be provided with a compressed elastic gas impermeable heat resistant pad disposed between the floor and the wall surface.

The sealing means may also comprise a flexible gas impermeable shape retaining material attached to one of the bottom and the wall and pushed against the other to form a friction seal when the bottom moves. This material may take the form of a rigid but somewhat flexible material, such as a stainless steel sheet. Another form of friction sealing is a pouch attached to one of the walls or the floor and pushed against the other. The bag may contain air, other fluids, or a flexible, elastic solid material.

On the other hand, the bottom may have first and second bottom sections that meet along a linear path. As mentioned above, the floor supports the combustion waste. The wall above the floor together with the floor constitutes a closed combustion chamber. In this case, the actuating means coupled to the first and second bottom sections and the wall surface move the first and second bottom sections with respect to the wall and with respect to each other along the first and second predetermined paths. An improvement here is that the sealing means are coupled to the first and second bottom sections and extend along at least a portion of the linear path. Such sealing means substantially prevents the passage of gas between the first and second bottom sections at a portion of the linear path when the actuating means moves the first and second bottom sections relative to each other.

The sealing means between the two bottom sections can take any form at the boundary between the floor and the wall as described above. In this case, the sealing means are related to (eg coupled to) one of the first and second floor sections, as well as to the other floor section in a manner very similar to the sealing means between the floor and the wall surface. Forms of sealing means may be friction sealing, membrane sealing, fiber pad sealing, fluid sealing. Friction sealing includes metal plate sealing and bag sealing. Both of these can be used for sealing between two moving bottom sections.

On the other hand, the system may have first and second surfaces that meet each other along a linear path. The actuating means coupled to the first and second surfaces move the first surface relative to the second surface along a predetermined path. An improvement of this system, the sealing means is coupled to the first and second surfaces and runs along at least part of the linear path. This sealing means must substantially prevent the passage of gas between the two surfaces in a portion of the linear path where the two surfaces meet when the actuating means moves the first surface along a predetermined path relative to the second surface. In particular, it must be sealed when the movement of the two surfaces by the actuating means deviates from the predetermined path.

Similarly, the form of sealing means at the boundary between the floor and the wall or between two bottom sections can also be applied between the two surfaces. As with the sealing means between the floor and the wall or between two bottom sections, this sealing means relates to (eg bonds to) one of the first and second surfaces and to the other surface.

Further, the sealing means between the bottom and the wall, between two bottom sections, or between the two surfaces may use two or more different types of the above-described types. This combination may be fluid sealing, friction sealing or a combination of membrane sealing and fiber pad sealing. On the one hand, the membrane seal and the fluid seal may be mixed regardless of the fiber pad seal (ie with or without the seal). Other combinations may be used, depending on the situation.

In order to completely enclose the combustion chamber, the moving furnace requires several sealing sections. Several seals take a horizontal and a vertical direction. If there are two furnaces, the seal between the two moving furnaces lies in the horizontal direction. As a result, different sealing types or combinations thereof can be achieved depending on the conditions of each sealing section to achieve a perfect sealing.

Waste-burning incinerators should improve the atmospheric quality of the surrounding or interior. Incinerators may be provided with a closed combustion chamber in addition to the waste inlet and the combustion product outlet. The combustion chamber has a floor and a wall for supporting combustion waste, the wall being located on the floor and sealing the surroundings with the floor. In addition, the wall surface and the bottom form a substantially closed combustion chamber. A method of improving air quality around or inside an incinerator is to move the floor against the wall along a predetermined path. It also includes preventing the passage of gas between the wall and the floor along at least a portion of the periphery when the floor surface moves away from the path by the actuating means.

In particular, to prevent the passage of gas between the wall and the floor, there may be a method of holding a flowable non-gas material on one of the floor and the wall along at least a portion of the perimeter between the floor and the wall. Hold the immersion device on the other side of the floor or wall along a portion of the perimeter, the portion of which is submerged in the material as the floor moves along a predetermined path.

Instead of using a immersion device, a flexible gas impermeable heat resistant film may be attached to both the floor and the wall along the perimeter. Alternatively, the compressed elastic gas impermeable heat resistant pad may be disposed between the floor and the wall along a portion of the periphery. Another method is to attach a sheet of flexible gas impermeable shape retaining material along one side of the perimeter to one of the floor and the wall and to push the material against the other.

As described above, the bottom may include first and second bottom sections that meet along a linear path. To improve air quality within or around this type of incinerator, the first and second bottom sections are moved along each other and against the wall along the first and second paths, respectively. The actuating means substantially prevents the passage of gas between the first and second bottom sections along at least a portion of the linear path as the first and second bottom sections move relative to each other.

A method of improving the air quality of at least one of the first and second surfaces that meet along a linear path is to move the first surface along a path relative to the second surface. It also includes preventing the passage of gas between the first surface and the second surface along at least a portion of the path when the first surface moves along a predetermined path but significantly deviates from the path relative to the second surface. .

The above-described technique may be applied to an incinerator in which the main combustion chamber is sealed as a method of improving air quality of at least one of two surfaces of an incinerator having two bottom sections. Instead of the relationship between the wall and the floor, two floor sections or two surfaces are considered here.

Depending on the installation location, two or more of the above methods may be combined. Also, in a closed space such as a combustion chamber, different techniques may be utilized in other parts. In particular, when the walls, floors or surfaces meet in a non-horizontal direction. Sealing the joints between two vibrating bottom sections, such as two furnaces, may require a different method than elsewhere.

Sometimes, depending on the combustion conditions of the incinerator, air may enter the combustion chamber through the gap between the floor and the wall. In this case, if the air pressure is maintained at a constant pressure, it is possible to prevent the combustion gas from leaking to the surroundings, especially when the natural ventilation and the artificial ventilation fail. In this case, the incinerator has a closed combustion chamber other than the waste inlet and the combustion product outlet. The combustion chamber has a bottom and a wall surface for supporting combustion waste, the wall surface being located on the floor and sealing the surroundings with the floor to substantially seal the combustion chamber. The improved incinerator has (a) container means which are coupled to the wall and the bottom outside the enclosed combustion chamber and extend along a part of the periphery and increase in gas pressure. In particular, the pressure should be higher than (1) the pressure in the combustion chamber and (2) the pressure outside the combustion chamber. The improved incinerator is also coupled to the vessel means and further comprises sealing means for maintaining a gas pressure inside the vessel means that is greater than (1) the pressure of the combustion chamber and (2) the pressure outside the combustion chamber. This increased air pressure causes air to enter the combustion chamber and prevents combustion gases from going out in the opposite direction, around the incinerator.

The aforementioned pneumatic sealing method may be used in combination with other types of sealing methods described above. Other seals block the air entering the combustion chamber through it or reduce the air volume. In practice, other types of seals can lower the amount of incoming air to a minimum negligible level.

The combustion chamber comprises actuation means, such as the vibrating mechanism disclosed in US Pat. No. 4,475,469, which actuation means can be coupled to the floor and the wall. By this actuation means, the floor moves relative to the wall along a predetermined path. In this case, the internal gas pressure of the container means is increased by the sealing means when the actuating means moves the floor deflected in a predetermined path.

The air quality around the incinerator can be improved even when the combustion chamber receives outside air through the seal without excessively adverse effects. In this case, the combustion chamber is sealed except for the waste inlet and the combustion product outlet. The combustion chamber itself has a floor and a wall for supporting combustion waste, the wall being located on the floor and sealing the combustion chamber together with the floor. A method of improving the air quality outside the incinerator is to increase the gas pressure inside the vessel means coupled to the wall and the bottom outside the enclosed combustion chamber and extending along at least a portion of the surroundings. Specifically, the internal air pressure of the container means should be higher than (1) the pressure inside the combustion chamber and (2) the pressure outside the combustion chamber in the peripheral portion. The gas pressure should be maintained high enough to force the gas into the combustion chamber.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The incinerator 75 shown in FIG. 1 employs two pulsation furnaces 76 and 77, a two-stage heat recovery device consisting of a radiator 78 and a boiler 79. To begin the process, put large solid waste into the hopper 82. This waste enters the main combustion chamber 84 by a ram loader 83. In the main combustion chamber 84 the waste falls to the first pulsation furnace 76 and is burned here with the heat of the burner 85 if necessary. The first pulsation furnace 76 moves combustion waste across the surface in the manner described in US Pat. No. 4,475,469, but from the inlet to the combustion chamber 84. Eventually, the combustion waste falls to the second pulsation furnace 77 where incineration continues. Air is supplied from the blowers 86 and 87 for the combustion process.

Waste burns and naturally releases thermal energy. Some of the thermal energy enters the radiator 78 and heats the fluid therein. The fluid heated in the radiator 78 enters the boiler 79 through the piping 88. The steam removed from the top of the boiler 79 can be used for construction purposes in the incinerator 75 as well as in power generation or heating.

The burned waste falls from the second pulsation furnace 77 to the ash tray 89 containing the water. Scoop 90, which is towed by cable 91 connected to motor 92, moves along track 93. The ashes from the scoop 90 into the hopper 94 fall into the bins 95.

The gaseous combustion product enters the passageway 102 in the combustion chamber 84, where it is combined with the raw material waste of the hopper 82, which is moved along the pipe 104 by the blower 103. This eliminates the odor of the raw material waste.

The gas enters the first reburn section 108 through the passage 102 and continues to burn at high temperatures with the aid of the auxiliary fuel burner 109 and the blower 110 to destroy combustible portions in the gas. As the incineration of the gaseous combustion product proceeds, the gas enters the second reburn section 111 and continues to burn. During this process, air is further introduced from the blower 112.

After the second reburn section 111, if there is a problem with the system, the gas exits to the safety stack 117. However, in the steady state, the chimney 117 is closed by the damper 118, so that the gas moves to the section 121 of the system. Here, additional cooling gas enters through the pipe 122. Therefore, the combustion gas is cooled down below the temperature at which various components such as zinc in the gas can exist in the gaseous state. Therefore, these components facilitate the cooling process so that the combustion gas does not condense in the piping of the boiler as it enters the boiler 79. Gas cooled to some extent passes through the boiler 79, the heat can be used for other purposes. As mentioned in the aforementioned U.S. Patent 4,438,705, two reburn sections 108,111 are located between the radiator 78 and the boiler 79. Because of this, enough heat remains in the gas in the reburn sections 108 and 111 to sufficiently burn the combustible components of the gas.

The gas exits boiler 79 and enters economizer 123 where it preheats the feed water to be used for radiator 78 and boiler 79. Thus, the economizer further saves thermal energy from the combustion process, which is supplied to the water passing through the system. The heat saved is added to the steam generation of the incinerator.

Part of the gas passes through the pipe 124 from the economizer 123 by the blower 125. Of course, this gas has removed a considerable amount of heat from the boiler 79 and the economizer 123, the temperature is lower than when entering the boiler and economizer. Thus, the gas entering the zone 121 through the pipe 122 lowers the temperature of the gas passing through the second reburn section 111.

The remaining gas enters the heat exchanger 133 from the economizer 123 through the pipe 132. The outside air enters the heat exchanger 133 by the blower 134 to further cool the gas. At this time, the gas has already removed a considerable amount of heat from the boiler 79 and the economizer 123. However, the temperature of the gas is still above the boiling point or dew point of the acid contained in the gas. The gas temperature in the heat exchanger 133 is lowered below about 400 ° F., where the acid in the gas condenses into the liquid phase. In this case, the acid can be neutralized by reacting with a base and then removed in a post-treatment process, which will be described later.

In the pipe 135, dry lime and activated carbon are mixed with the exhaust gas to neutralize condensed acid and remove contaminants. This gas enters the baghouse 138 where the particulate matter is separated. The solid material falls into the trash can 141 and is waited for in a discarded state.

Clean gas from the baghouse 138 passes through the pipe 142. At this time, waste and gas in the incinerator in operation do not enter the pipe 142 from the pipe 143, because the damper 145 is closed by the motor 144 to flow the combustion gas only to the baghouse 138. to be.

The gas in the pipe 142 is sucked by the draft blower 148 and discharged into the atmosphere through the exhaust chimney 149. The monitor 150 evaluates various combustion products included in the flue gas exiting the chimney 149. These combustion products include particles, carbon compounds, nitrogen oxides, sulfur, and the like. The exact task of the monitor 150 may vary depending on the situation, including factors such as waste being incinerated, and location of the incinerator.

During the startup process, the incinerator 75 is heated to operating temperature using natural gas in the burners 85 and 109 and then begins to receive the actual waste. During this warm up, the components to be removed from the baghouse 138 are not actually contained in the exhaust gas. Under these limited conditions, the damper 145 can be fully opened and bypass the backhouse 138 to allow the exhaust gas to flow directly through the pipe 143 to the pipe 142 and the chimney 149. However, when incinerator 75 reaches operating temperature, it closes damper 145 as described above and allows exhaust gas to enter baghouse 138.

2 shows a pulsation furnace 158 located within the combustion chamber 84. An inflation bag 159 connected to yoke 160 pushes against stop 161 to provide pulsating motion in the direction of arrow 162 as described in vector diagram 163 and US Pat. . The blower 165 acts through the pipe 166 to impart air pressure around the pulsation furnace 158 and inside the combustion chamber 84. Depending on the shape of the gap between the pulsation furnace 158 and the combustion chamber wall surface, this air pressure may be sufficient to effectively seal the exterior of the combustion chamber 84 against the gas inside.

However, in many cases, more aggressive sealing is required than sealing by air pressure. For example, due to air pressure, the air level inside the combustion zone may be inappropriately high. Thus, it may be appropriate to physically seal around the pulsation furnace. For this seal to be effective, this movement must be accommodated when the pulsating furnace is pulsating. This is especially important because the movement of the pulsating furnace cannot be predicted. Therefore, devices such as airbags may not always produce the same or symmetrical movement. In addition, because the weight of the waste is variable, the movement of the pulsation furnace may be out of normal.

As shown in Figs. 2 and 3, isolation of the combustion zone inevitably results in several zones that are difficult to actively seal. The characteristics and structure of each seal depend on the location of the furnace and the type of seal. Therefore, the pulsation furnace 158 has a horizontal horizontal sealing part 167 of the upper loader side, the horizontal horizontal sealing part 168, the side vertical sealing part 169, and the horizontal horizontal sealing part 170 of the lower part. The seal in this position can be used in place of or in combination with the air seal described immediately above. In addition, the following description concentrates on the sealing part of one part of an incinerator. Of course, all the sealing sections are connected to one another and surround the periphery to keep the inside of the combustion chamber airtight with respect to the outside. In addition, the following description can be based on the specific structure of one sealing part. Of course, the same structure can be applied to other positions of the furnace with little modification or change. In this case, the description of any one seal applies equally elsewhere.

4-9 is a method of attaching a spring metal piece made of spring steel or the like to the pulsation furnace 158 or the outer wall surface. This piece of metal pushes against the other surface, creating a frictional and sliding seal. This type of basic seal is indicated at 173 in FIGS. 4 and 5. The corrosion resistant spring stainless steel metal strip 174 generally takes the Z shape. In FIG. 5, the legs 175 of the Z-shaped metal strip 174 are in close contact with the wall surface 176. The intermediate section 177 of the Z-shaped metal strip extends between the wall surface 176 and the pulsation furnace 158. Finally, the bending section 178 is in close contact with the pulsation furnace 158 itself. When the pulsating furnace 158 is pulsating, the bending section 178 of the metal strip 174 slides along the pulsating furnace. The metal strip 174 is in close contact with the wall 176 such that the bending section 178 is continuously pushed against the pulsation furnace 158. Use of lubricants such as molybdenum sulfide grease or dry aerosol lubricants can minimize wear when the bending section 178 slides in the pulsation furnace.

Because of the elasticity of the metal strip 174, the bending section 178 remains in contact with the pulsating furnace even when the pulsating furnace 158 is moved. Likewise, the pulsation furnace 158 itself may move slightly laterally while pulsating. That is, the pulsation furnace 158 is slightly distant or approaching the wall 176 while pulsating. However, the elasticity of the metal strip 174 covers this movement, and the bending zone 178 continues in contact with the pulsation furnace while the pulsation furnace 158 is moving to form a continuous seal.

As described above, the seal 173 by the metal strip 174 serves two functions. Firstly, the combustion gas of the pulsating furnace 158 is minimized to the outside of the incinerator and, if possible, prevented. This sealing is very important because the gas in the combustion chamber is particularly harmful to the workers near the incinerator. This is especially true when the incinerator is in a closed room.

Second, the seal 173 restricts outside air from entering the incinerator. As stated in the aforementioned applicant's patent, to protect the environment in burning waste, all incineration factors must be strictly controlled in both the combustion chamber and the reburn section. In particular, the amount of air entering the combustion chamber, the location of the inlet and the temperature of the incoming air should be controlled. The seal 173 serves to minimize the adverse effect on the incineration of the interior by minimizing the air entering the pulsation furnace surroundings. The properties of this seal 173 and other features described below are particularly important in view of the fact that the combustion chamber (as well as the reburn zones) should operate at negative pressure relative to the surrounding environment. These negative pressures can be caused by natural or draft vents following combustion. One or both of these wind sources (ie negative pressure in the combustion chamber) cause the combustion gas to face the chimney. This ventilation draws air around the pulsation furnace without disturbing the seal and adversely affecting combustion conditions.

On the other hand, a partial static pressure may be generated inside the combustion chamber. This may be caused by a breakdown of the natural air suction blower. In addition, rapid incineration of volatiles in the waste can lead to increased pressure in the combustion chamber. Nevertheless, by the above-mentioned seal, it is possible to prevent the gas inside the combustion chamber from leaking out and damaging the surroundings.

6 shows a modification of the lateral horizontal frictional sealing part in which the metal strip 185 is fixed to the wall surface 176 with the bolt nut pair 184. The strip 185 is in close contact with the pulsation furnace 158 to prevent the passage of gas. However, in FIG. 6, tension spring 187 is hung between strip 185 and bottom 188. Since the tension spring 187 pulls the strip 185 down, the strip is in close contact with the pulsation furnace even when the pulsation furnace 158 pulsates. Naturally, the incinerator is structurally accessible to the spring 187 and the connecting cable for troubleshooting or replacement.

7 slightly changes the configuration of FIG. Here, the bolted strip 192 is inclined downward toward the pulsation furnace 158. Compression spring 194 pushes the strip upwards to bring it into close contact with pulsation furnace 158. 8 is another variant, in which the strip 196 is secured to the pulsating furnace 158 itself by bolts 195. The strip 196 slides against the wall 176 to form a friction seal. Here, the strip is tightly attached to the wall 176 by the tension spring 197 to form a seal. As with other friction seals, lubricants should be used to avoid excessive wear of the spring metal strip. Incidentally, the incinerator is structurally capable of repairing various sealing elements. The springs are to be arranged on the side of the incinerator where the sparks do not reach. This protects the spring from the effects of the combustion environment.

9 shows a spring metal strip 201 used for the loader side horizontal friction sealing at the top. A bolt 202 is used to secure the strip 201 to the loader side end wall 203 of the incinerator, and the strip is also supported on a shelf 204 fixed to the pulsation furnace 158. Since the tension spring 205 pulls the strip 201 to bring it into close contact with the shelf 204, sealing reliability is secured. The shelf 204 is positioned in the pulsating furnace 158 in line with the strips 185, 192, 196 of FIGS. 6, 7, 8 to seal continuously around the front edge of the furnace. This arrangement is shown in FIG.

Similarly, FIG. 10 shows a state where the spring metal strip 208 used for horizontal frictional sealing on the lower ashing side is in frictional contact with the bottom of the pulsation furnace 158. The strip 208 is installed on the bottom surface 210 with bolts 209, and the strip 208 is in close contact with the furnace 158 by the tension spring 211.

11 shows a metal strip 215 used for vertical side sealing near the back end 2160 of the furnace 158. Similarly, the strip 215 rubs against the furnace 158 along line 217. FIG. The top 218 of the line 217 is connected to the horizontal side strips 185, 192, 196 of Figs. 6-8. The bottom of the sealing line is connected to the strip 208 of Fig. 10, closing the periphery.

Details of the vertical friction sliding seal are shown in FIGS. 12-14. The short legs 224 of the metal strip 223 slide the sides of the furnace 225. Bolt 228 secures strip 223 to bracket 229, which bracket is secured to post 231 by bolt 230. The strip 223 is held on the side of the furnace 225 by the bracket 229.

15 shows a furnace 225 moving to the right in the direction of arrow 162. The strip 236 is secured to the column 237 along the bracket 238 by bolts 239 in contact with the furnace. The tension spring 240 is connected to the plate 241 fixed to the post 242. The other end of the spring 240 is hooked to a ring 241 attached to the metal strip 236. Because of the tension of the spring 240, the metal strip 236 is tightly sealed to the furnace even when the furnace 225 pulsates. The metal strip 236 of FIG. 16 is different from FIG. 15, where the compression spring 245 pushes the strip towards the furnace 225. The spring 245 is fixed to the outer wall 247 by the bolt 246. 15 and 16 respectively look down on the vertical sliding seal.

17 shows another structure of a metal strip 251 made of spring steel used for friction sliding seals. The metal strip 251 has an S-shaped shape, and contacts the furnace at the upper curved portion 252 and the fixed structure 253 at the lower curved portion 254. The strip 251 is fixed to the angle bracket 255 installed on the shelf 257 by bolts 255. Finally, since the shelf 257 is fixed by the bolt 258, the strip 251 is fixed to the fixed structure 253.

As described above, due to the curved structure of the strip 251, the sliding friction sealing effect can be seen in two places. The first seal occurs at the top surface 252, where the strip 251 is in contact with the furnace 158. A second seal occurs at the bottom curved portion 254 where the strip 251 slides along the fixed structure 253. Thus, the combustion gas in zone 259 cannot affect the exterior 260 away from the combustion flame or the rest of the strip seal. In addition, a strip 251 is sandwiched between the furnace 158 and the stationary structure 253 to help tight and secure sealing. In particular, the curved spring steel metal strip 251 must be pressed into the gap between the furnace 158 and the foundation 253. When the metal strip is finally installed in this position, it is held in place because of its elasticity. The metal strip 251 tends to return to its original shape, making the double seal described above while pressing the furnace 158 and the foundation 253. In the sliding friction sealing, it is necessary to apply lubricating oil such as molybdenum sulfide to the contact portion to increase the life of the seal and to facilitate maintenance.

18 illustrates a structure for protecting the metal strip 174. The nozzle 264 sprays the cooling fluid 265 onto the strip 174 to cool the various zones 175, 177, 178, 179. The cooling fluid 265 may be a liquid such as water or a gas such as air. In any case, the cooling fluid 265 protects the metal strip 174 from the heat generated in the zone 267 between the furnace 158 and the outer wall 176. When high heat is applied, the metal strip 174 may be destroyed and may be adversely affected. If the incinerator is not ventilated and the flame leaves the combustion chamber, heat can be generated. Since the metal strip loses its elasticity no matter how briefly it is heated to a temperature below the break point, the metal strip is likely to lose its ability to come into contact with the furnace 158 and block the entry of gas into the interior region 267.

The nozzle 264 receives cooling fluid from the pipe 270 through the control valve 271. The valve 271 is manual and is turned on and off depending on the state of the incinerator. Opening the valve ensures a stable supply of cooling fluid throughout the time the incinerator is running. On the other hand, the valve 271 may be mechanically operated under the control of the heat radiation type temperature sensor 272. When sensor 272 determines that the temperature of strip 174 has risen to a certain value, valve 271 is opened to cool strip 174. Otherwise the valve 271 is closed. On the other hand, the valve 158 may simply open and close intermittently when the furnace 158 actually pulsates. In either case, the fluid from the nozzle may form an air knife outside the furnace 158 to block combustion gas and outside air in the incinerator 267.

In FIG. 19, the cooling fluid source takes the form of a box 273 that receives high pressure air from the blower 274. High pressure air is exhausted from the box 273 through the nozzle line 276 arranged along the surface of the furnace 158 to cool the metal strip 278. The blower 274 may continue to operate or may be controlled by the temperature sensor 279 in a manner similar to that shown in FIG. 18. Alternatively, the blower may supply air intermittently. Air from the nozzle line 276 acts as an air knife like FIG. 18. This interrupts the flow of gas to the ignition zone 267 between the metal strip 278 and the pulsation furnace 158.

20 shows a state in which an interchangeable sliding sealing metal strip 284 is attached to the wall protrusion 285. Tightening nut 286 to stud 287 places strip 284 in place. In operation, the edge 288 of the metal strip 284 is in sliding contact with the vertical metal plate 289 attached to the furnace 158 to provide a friction seal.

As shown, ash 290 may collect in interior 291 of strip 284. In this case, the metal strip 284 is pulled downward, and the ash 290 may be dropped on the floor. If the sealing strip 284 is damaged due to heat, corrosion or the like, the nut 286 may be loosened and replaced with another one.

In FIG. 21, the expansion bag at position 295 replaces the horizontal sliding friction seal between the furnace 158 and the wall surface 296. The bag 298 is secured to the shelf 297 and contains air, gas or other fluid therein. As the furnace 158 moves, the bag 298 slides against the wall 296. Bag 298 should have sufficient elasticity to accommodate the vertical and horizontal motion components of the furnace. It should also have some degree of lubricity at the point of contact between wall 296 and bag 298. The surface of the bag 298 should have self-lubrication or should be lubricated as described above. Of course, the material of the bag 298 should be fire resistant.

On the other hand, the bag 298 may be fixed to the wall surface 296 and made to slide on the shelf 297. The bags of the type shown in FIGS. 21 and 22 are applicable to all types of sealing of incinerators, as well as those shown in FIGS. 2 and 3 as well as cross sealing between several moving furnaces. The bag 301 of FIG. 22 is filled with solid material 302 rather than simply inflatable. Such solid materials include sand, gravel, silica, alumina and the like. The material 302 must have sufficient elasticity to swell enough when the furnace 158 moves toward the shelf 297 and then regain its original shape when the furnace and shelf open. Of course, the bag 298 of FIG. 21 may be applied to the bag 301 of FIG. 22.

23 and 24 show a state in which the horizontal cross bag-shaped seal 304 on the receiving side contacts the bottom 305 of the furnace 158. The seal 304 is composed of a rubber tube 307 fixed to the support bracket 309 by bolts 308. The bracket 309 is installed on the fixing bracket 310, and the fixing bracket 310 is fixed to the foundation structure 312 by bolts 311. When the nut 315 is tightened to the screw rod 316 attached to the bracket 309, the height of the rubber tube 307 can be adjusted.

25 and 26 also show a bag-shaped seal 320. The flexible flame retardant film 322 is fixed to the furnace 158 and the outer wall surface 323 by the bolt 321. The membrane 322 should of course have sufficient elasticity to accommodate the pulsation of the furnace 158 in the direction of the arrow 162. As indicated by the vector diagram 163 of FIG. 3, this pulsating motion includes, among other things, a horizontal forward and backward motion component. Membrane 322 has no problem in receiving horizontal motion components. However, the furnace 158 also has a vertical motion component. This vertical motion component imposes significant stress on the film 322. Thus, the membrane 322 must have sufficient elasticity and flexibility to accommodate both of these bidirectional kinetic components. Membrane 322 can be folded well when furnace 158 is pulsating. However, the film should be made of a material which prevents wrinkles which may adversely affect the sealing performance.

27-31, another form of water seal is shown. In particular, a side horizontal water seal 327 is shown in FIG. 27. A barrel 328 containing water 329 is installed on the outer wall surface 330. The metal strip 331 is connected to or integrally formed with the crosspiece 332, and the crosspiece is watertightly connected to the furnace 158. A blade 331 in the water 329 creates a fluid barrier between the interior 333 and the exterior 334 of the furnace. As shown, the bucket 328 easily accommodates the movement of the furnace 158 in the vertical direction in the figure. Due to the depth of the water bottle 328, the furnace 158 remains sealed during the vertical movement of the furnace 158, and the furnace can rise to 4 inches during pulsation.

28 shows the loader side horizontal transverse water seal 340 at the top. Blade 342 in water 343 is connected to a shelf 341 attached to the furnace 158. A barrel 344 containing water 343 is installed on the fixed surface 345. Since the water 343 jumps out when the bucket 344 moves with the furnace 158, the bucket should not move even if the furnace moves. In addition, the blade 342 is inclined in the moving direction of the furnace when the furnace moves in the direction of the arrow 162. This prevents the blade 342 from releasing the water 343 from the bucket 344 when the furnace 158 moves to the left as shown in FIG. 28. Similarly, water seal 340 serves as a barrier between combustion chamber interior 347 and exterior 348.

FIG. 29 shows a horizontal transverse water seal 350 on the ashing side. The blade 351 is attached to the bottom surface of the furnace 158 and immersed in water 352 in the keg 353. As described above, the bucket 353 is provided on the fixed surface 354 so that the water 352 does not spill even if the furnace 158 pulsates. In addition, the blade 351 moves in the direction of the arrow 162, so that the water 352 does not float even if the furnace moves to the left as shown in the drawing.

30 and 31, another vertical side water seal 360 is shown. Vertical water seals are difficult to construct because of their orientation. All horizontal water seals use blades submerged in an open horizontal bucket, but this cannot be adopted with vertical water seals. The vertical bucket consumes all necessary water. 30 and 31 show the configuration of the vertical water seal. The bucket 361 consists of three side walls 362-364 and a bottom 365. The two side walls 362 and 364 have protrusions 366 and 368, respectively, and the bottom 365 also has protrusions. The side walls 362 and 364, the bottom 365, the protrusions 366 and 368 and the bottom protrusions are all composed of a flexible heat resistant elastic material such as rubber.

The water tank 361 is pushed against the pulsation furnace 158 by the compression spring 373 fixed to the outer wall surface 374. This minimizes the loss of water between the bucket 361 and the furnace wall because, due to the elasticity of the side walls 362, 364, the bottom 365 and the associated protrusions, these side walls, the bottom and the protrusions act as wipers for the furnace 158. do. Also, as the furnace 158 moves in the direction of the arrow 162, the sidewalls, bottom and protrusions act as wipers across the surface of the furnace, again minimizing water loss.

In any case, however, it is inevitable that water leaks from the bucket 361, especially while the furnace 158 is in motion. To replenish this leak, the supply line 375 is connected to a bucket 361 and a reservoir 376. Water from the reservoir 376 is replenished with water leaking from the bucket 361. Normally, a floater is used to maintain the water level in the reservoir 376 at a height sufficient to replenish the leak of the water bottle 361.

As described above and shown in FIGS. 27-31, the circumference of the furnace 158 is completely sealed. Thus, there is one pulsation furnace 158 and a horizontal seal 327 on the side of the combustion chamber of the incinerator surrounding the water seal furnace (see FIG. 27), and a horizontal transverse seal 340 at the loader side end of the furnace 158. (See FIG. 28), the bottom of the back side has a horizontal transverse seal 350 (FIG. 29), and the side of the furnace between the side seal 327 and the lower seal 350 has a vertical side seal 360. (FIGS. 30 and 31). In addition, in order to prevent leakage at the connection portions of the two seals, when the seals have the same height, they must be formed in a continuous pool shape as shown in FIGS. 50-53. Seals that use a continuous pull include a horizontal side seal 327 and an upper loader side horizontal seal 340. In theory, the side vertical seal 360 may do so even if the leak problem may affect other seals.

Water seals (or other types of seals) may be applied throughout the circumference of the furnace. Therefore, the water seal of FIGS. 27-31 can also be used for sealing the entire circumference of the furnace. However, there is no need to do so. In particular, the vertical water seal 360 shown in FIGS. 30 and 31 is primarily at risk of leakage. Therefore, the incinerator configuration utilizing the water seal in all sections except the vertical seal can be adopted. The vertical seal may take the form of a friction seal as described above. The vertical seal, whatever its shape, should be in close contact with the water seals on the side and bottom that connect to it.

The buckets 328,344, 353 described so far and the buckets to be described later are made of stainless steel to avoid corrosion by combustion gases. The same is true for blades 331,342 and 351. In particular, the combustion gases may contain chlorine which dissolves in water to produce hydrochloric acid. Stainless steel does not corrode in hydrochloric acid. For further protection, a base that neutralizes the acid may be added to the water. When the combustion gas is dissolved in water to produce a base, neutralizing acid can be added to the water.

The water 329, 343, 32 in the buckets 328, 344, 353 has another advantage. In particular, it functions to cool the blades (331, 342, 351). These blades are directly or indirectly exposed to hot gases during operation of the incinerator. In hot environments, the blade can break. Water cools the blades to prevent this breakage. The same applies to the day used for the lower water seal. Another feature of certain seals, the heat resistance problem, can be solved by using fiber pads. However, the use of water avoids high temperatures that can damage the blade made of stainless steel.

32 and 33, the horizontal horizontal seal 379 on the lower back side is shown. It can be seen that this is very similar to the configuration of Figs. However, there is a difference in that the barrel 380 containing the water 381 fits in the groove 382 of the support 312 while being supported by the adjustment bracket 309. At the bottom of the bucket 380 is a drain 385, where water 381 can be drawn out.

Bolts 386 connect the impermeable flexible membrane 387 to the bottom 305 of the furnace 158 so that no gas leaks. Membrane 387 may be a 1/8 inch thick aramid fabric, a mixture of Kevlar and Nomex manufactured by Dupont, Wilmington, Delhi. Other bags of rayon, fiberglass gore-tex, and other micron-spaced fabrics may be used. You can also vary the thickness. The bottom of membrane 387 is immersed in water 381 to prevent gas leakage between incinerator interior 388 and exterior 389. The bottom of the membrane 387 is attached to the weight 390 to be submerged in water. As noted above, the bottom horizontal seal 379 should align with all types of side vertical seals 391.

The seal 394 of FIG. 34 is very similar to the water seal 379 of FIG. 33, but differs in that a rigid blade 395 made of stainless steel is immersed in water 381 and sealed. Blade 395 is secured with bolt 386 (nothing comparable to weight 390).

35 and 36 show upper horizontal water seals 401 and 402 similar to the lower seals of FIGS. 33 and 34. Both have a fixed bucket 403 installed in the foundation 404 to contain the water 405. The bucket lid 408 serves as a partition between the combustion zone 409 and the exterior 410. The bucket 403 can be cleaned. The lid 408 is connected to the fixture 412.

In FIG. 35, the support plate 413 is connected to a clip 414 attached to the furnace 158. The bolt 417 connects the membrane 418 of a material similar to that of FIG. 33 to the support plate 413. Membrane 418 is submerged in water 405 by weight 419. In FIG. 36, instead of the film 418, a stainless steel sheet 422 is connected to the support plate 413 by bolts 417. Like other steel sheets used for transverse sealing on the loader side or the ashing side, the steel sheets 422 are inclined at a relatively small angle with respect to the horizontal plane. This prevents the water 405 from splashing out of the bucket 403 by the steel plate 422 even when the furnace 158 vibrates in the direction of the arrow 162. Membrane 418, like others, shakes less water during oscillation of the furnace than a hard blade.

37 and 38 show horizontal water seals 425 and 426 on the loader side, respectively. In both of these, the bucket 428 rests on the support structure 427 so that the water 429 does not leak. The support plate 430 is connected to the pulsation furnace 158 with a clip 431. The retainer strip 435 and the stainless steel plate blade 436 are supported by the support plate 430 by the bolt 434 (FIG. 37). The blade 436 is submerged in water 429 to seal between the interior 437 and the exterior 438. The water seal 425 is connected in line with the lateral horizontal seal, indicated by the horizontal line 439. This relationship takes the configuration described in Figures 50-53. The lid 440 opens about the hinge 441 and thus has access to water 429.

In FIG. 38, the flexible flame retardant film 442 submerged in the water 429 by the weight 443 is secured to the bolt 434 and the retainer strip 435. The flame resistant film 442 in the water 429 seals between the interior 437 and the exterior 438. On the other hand, this configuration can also be applied to FIG.

39 and 40 show the horizontal water seals 447 and 448 on the lower back side, respectively, which are very similar to the water seal 394 of FIG. However, these seals 447 and 448 are used when the 451 part combustion gas reacts with the water 381 in the seal 394. This situation can occur when the waste contains a lot of things such as disposable diapers. When the absorbent polymer gel in the diaper evaporates and is dissolved in water 381, it forms a colloidal gel with water and solidifies. This clearly interferes with the "fluid seal" action described above.

Therefore, sand 452 is used in the barrel 380 of FIG. 39 without using water as a sealing medium. Similarly, bubble material 453 is used in FIG. 40. In the case of Figure 40, it may be made of silica or alumina pieces or particles. Fluids 452 and 453 in FIGS. 39 and 40 are placed on micromesh 456 welded to barrel 380. Air is supplied to the gap 458 between the net 456 and the bottom through an air pipe 457 placed between the bottom of the keg 380 and the net 456. This air rises through the net 456 to help flow of the fluids 452 and 453. The pipe 457 may supply air continuously or intermittently or not at all, depending on the nature of the waste being incinerated. For reference, FIGS. 62 and 64 show the use of a medium through which air or gas does not penetrate at all. However, it is possible to supply air intermittently from the tube 457 to match the vibration of the furnace 158. That is, the air can be supplied for a short time only before and after the vibration. This is particularly important because the internal gas pressure in the combustion chamber can rise slightly due to the vibration of the furnace. If the desired ventilation is not achieved during this particular period of time, the use of an air pipe 457 is recommended.

When air is supplied from the air pipe 457 to the keg 380, fluid flow occurs outside the furnace 158. As in the case of Figs. 18 and 19, this flow acts as an air knife to prevent combustion gas outflow from the interior 451 of the furnace.

Similar seals 461 and 462 are shown in FIGS. 41 and 42. The tube 403 is welded with a fine web 463 and a tube 464 beneath it. Air or gas flows into the space 466 under the network 463 through these pipes 464. Sand 467 is filled on the mesh 463 of FIG. 41 and bubble material 468 is filled in FIG. In either case, the blade 422 is submerged in sand 467 or bubble material 468 to serve as a seal. 39 and 40, gas may be continuously or intermittently supplied to these spaces through these tubes, depending on circumstances, to improve the fluidity of the materials 367 and 468, but not at all. As in FIG. 36, these seals 461 and 462 are connected to the side horizontal seals along line 410.

As shown in FIG. 1, the incinerator may have two furnaces 76, 77 or more. Fully sealing the combustion chamber also requires sealing the connection between the two furnaces. Sealing between the two furnaces takes a lot of effort. First, both furnaces vibrate, and the second two furnaces have different vibration speeds, for example, the lower furnace may be less vibrating than the upper one. Third, both furnaces can be eccentric. The water seal between the two furnaces entails substantially horizontal sealing on the lower back side for the upper furnace and horizontal sealing on the upper loader side for the lower furnace. Each of these seals consists of immersing the blade in a bucket installed on a stationary object. This intermediate water seal will be described with reference to FIGS. 43-48 and 57. On the other hand, the seal between the two furnaces may be a seal of a type other than the water seal type.

43 and 44 show a system in which two furnaces 158a and 158b operate in line. These furnaces oscillate in the directions of the arrows 162a and 162b, but the oscillation period and the intensity of the furnaces 158a and 158b are different from each other. This situation is consistent with the twin furnaces 76,77 of FIG. On the other hand, the main combustion chamber may be provided with three or more furnaces, as shown in FIG. In practice a horizontal transverse seal 475 can be applied between the two furnaces.

As shown in Figs. 43 and 44, this seal 475 does not connect the horizontal return side seal 476 and the loader side horizontal seal 477 at the top. The former is the form shown in FIG. 34 and FIG. 37 is the latter form. In FIG. 43, the blade 478 of the upper furnace 158a is immersed in water 479 in the bucket 480 installed on the fixed surface 481. Likewise, blade 485 of lower furnace 158b is also submerged in water 479. Water 479 in which two blades 478 and 485 are enclosed seals between combustion zone 486 and exterior 487.

The seal consisting of the blades 478 relative to the upper furnace 158a is aligned with the side vertical seals, indicated by broken lines 488. Likewise, the seal 477 consisting of the blade 485 of the lower furnace 158b is aligned with the upper side seal, indicated by broken line 489. The two blades 478 and 485 are located on the same horizontal plane as the sealing line 489. This relative position of the seal closes the periphery, resulting in a continuous seal around the two pulsating furnaces 158a, 158b.

44 shows that the bucket 480 is installed in the fixed structure 481 but does not contact the upper furnace 158a or the lower furnace 158b. In this case, the water 479 does not overflow the bucket 480 even when the furnace moves.

45 shows the same intermediate horizontal transverse seal 490 as the conventional seal 475 between two furnaces 158a and 158b. Likewise, the bucket 491 is placed on the fixed surface 492 and contains water 493 therein. The blades 494 and 495 of the upper and lower furnaces 158a and 158b are immersed in the water 493, respectively, to form a water seal. 45, however, there is an additional seal 496 made of compressible elastic fiber pads 497 between the furnaces 158a, 158b. The pad 497 is connected with an alloy pin 498 to a steel plate 499 covering the fire resistant coating 500 of the lower furnace 158b. As one or two of the two furnaces vibrate, the fiber pad 497 rubs against the steel plate on the bottom surface of the refractory coating 503 of the upper furnace 158a. However, even when the furnaces 158a and 158b are closest, the fins 498 should be short enough to not contact the steel plate 502 of the upper furnace 158a.

Similarly, lubricant oil such as molybdenum sulfide is applied between the pad 497 and the upper furnace 158a to smooth the movement of the pad. Lubricant oil is typically sprayed on both the pad 497 and the steel plate 502. The pad 497 has a fire resistance like lubricating oil so as to be protected from the heat of the flame in the combustion chamber 04.

The pad 497 should be resistant to high temperatures and gases formed in the combustion chamber 504. The fiber pads 497 should have sufficient compressibility and elasticity (ie compression elasticity) to fill the gaps 505 between the furnaces as the furnaces 158a and 158b move toward each other and the spacing therebetween varies. Pads made of aluminum oxide, silicon oxide or mixtures thereof serve this function.

The pad 497 isolates water 493 from the combustion chamber 504, which is the hot corrosion gas environment of the incinerator, which can damage the seal 485 in particular. Thus, the pad must also function as a firewall. However, pad 497 is not a complete seal so that gas may leak out of pad 497, while water 493 may block all such gases. Depending on the waste burned, it may be sealed only with water 493 without the pad 497. Similarly, only pad 497 may be used without water seal 490.

To seal between the furnaces 158a, 158b with the pad 497, a vertical seal of the furnace 158a must be formed along the line 506. This closes the perimeter completely to ensure a perfect seal. As shown in Fig. 45, a fiber pad similar to the pad 497 may be formed with the upper and lower horizontal seals on the loader side and the backing side together with other types of water seals.

46 shows the same water seal 490 and pad seal 507 as a conventional vertical seal. However, here, the pad 508 rubs against the steel plate 509 provided in the recess 510 of the fireproof wall 503 of the bottom surface 511 of the upper furnace 158a. When the two furnaces 158a and 158b move relative to each other, the recess 510 controls the movement of the pad 508 fixed to the lower furnace 158b by the pins 512. Everything else is the same as in FIG.

47 shows the intermediate horizontal transverse water seal 512 between the upper and lower furnaces 158a and 158b. This is very similar to the water seal 475 of FIGS. 43 and 44, but two furnaces 158a and 158b are connected to flexible membranes 513 and 514, which are submerged in water 515 in the tub 516. Weights 517 and 518 are attached to the bottoms of the membranes 513 and 514 so that the bottoms of the membranes are immersed in water 515. The side vertical seal 517 of the upper furnace 158a coincides with the membrane 513. Similarly, the side horizontal seal coincides with the line 518 of the lower furnace. This closes the circumference of the two furnace connections to seal between the combustion chamber 519 and the exterior 520.

The seal 521 of FIG. 48 is the same as the seal 475 of FIG. 44. Therefore, the same reference numerals in both drawings. However, the seal of FIG. 48 has two different features. First, a flexible elastic fibrous pad 522 is fixed to the lower furnace 158b with a pin 523. The pad 522 functions like the pads 495 and 504 of FIGS. 45 and 46.

The seal 521 also includes a bag 523 secured to the blades 478 and 485 via support strips 525 and 526. This bag 523 must completely surround the blades 478 and 485 for effective sealing. The bag should have sufficient elasticity to accommodate movement in the direction of the arrows 162a, 162b of the furnaces 158a, 158b. Finally, the bag 523 must be able to withstand the environment of the combustion chamber 486. The same material as that of the film 322 of FIGS. 25 and 26 may be applied to the bag 523.

Three elements of the seal 521 of FIG. 48 are the bag 523, the water 479, and the fiber pad 522. Depending on the internal environment of the combustion chamber 486, the seal 521 may be functional only with one or two of the above three. In particular, the two blades 478 and 485 serve to immerse the bag 523 in the water 479 and serve as water seals when the bag 523 is not functioning properly. Therefore, if there is no water 479 or the water bottle 480, the blades 478 and 485 are not needed in the sealing part 521, either.

49 shows a combustion chamber 527 which is very similar to the combustion chamber 84 of FIG. 1 but seen from the other side. Combustion chamber 527 includes upper and lower furnaces 158a and 158b. The cable 531a is wound around the circular beam 532a of the fixed structure 533 and the beam 534a of the furnace 158a. The furnace 158a may be suspended in the fixed structure 533 via the cable 531a so that the furnace 158a pulsates in the direction of the arrow 162a as described in the above-described US Patent 4,475,469. Similarly, the lower furnace 158b is also suspended by the beam 532b of the fixed structure 533 and the cable 531b wound around the beam 534b of the furnace 158b.

The upper furnace 158a has a loader side transverse seal and a bucket 537, a side horizontal seal and a bucket 538a, a vertical side seal 539a and an intermediate horizontal seal and a bucket 540. Similarly, the sealing periphery of the lower furnace 158b includes an intermediate horizontal seal and a bucket 540, a side horizontal seal and a bucket 538b, a side vertical seal 539b, and a lower back receiving side horizontal seal 541. Have Since all the above sealing portions are connected to each other and completely enclosed, the surroundings of the furnaces 158a and 158b are completely sealed to separate the inside and the outside of the incinerator. A water bottle is used for all the seals other than the vertical seals 539a and 539b. As shown, the vertical sealing portions 539a and 539b use the above-mentioned friction sealing or bag sealing. The connection of the water seals of the lower furnace 158b is shown in FIGS. 50-53. The same pattern applies to the upper furnace 158a, although slightly shorter.

The system connecting the water reservoirs to the lower furnace 158b of FIG. 49 is indicated at 545 in FIG. 50. Both horizontal buckets 546 were connected to the upper horizontal buckets 547. This bucket system 545 is fixed to the fixture 533 of FIG. A similar structure is applied to the bucket system 545 of the upper and lower furnaces 158a and 158b, so it can be seen that it is applied to the general furnace 158.

Water in the side bucket 546 and the transverse bucket 547 flows freely at the corner 548, one of which is shown in FIG. 51. As shown, the horizontal lateral sealing bucket 547 is indicated by a broken line behind the lateral horizontal sealing bucket 546. These two buckets are connected to each other and either water freely flows to the other to provide a continuous seal. The two buckets are connected to each other at the connector 552 and can access the bucket 547 through a lid 553 connected by a hinge 554.

52 shows the corner 555 of the pulsation furnace 158. The side edge 556 is attached to the side wall 557 of the furnace 158. At one end of the furnace 158 is a flexible horizontal membrane 418 (shown in FIG. 35). As shown in FIG. 52, the flexible membrane 418 adheres to the side edges 556 to prevent the passage of gas. Similar side edges are disposed at the other end of the membrane 418 but are not shown in the figure. This continuous connection of the side edges 556, membrane 418 and side edges is immersed in the bucket structure 545 of FIG. 50 filled with water to form a continuous water seal for the three sides of the furnace 158. To complete the seal, two vertical seals are connected to the bottom of the end 558 of the side bucket 546 of FIG. 50. The bottom horizontal transverse water seal is connected to the bottom of the vertical seal to close the furnace periphery.

The furnace 158 of FIG. 53 is very similar to the furnace of FIG. 52, but uses a stainless steel blade 422 (similar to that shown in FIG. 36) instead of the flexible membrane 418. Likewise, an airtight portion is formed along line 559 where the side edges 556 and the blade meet to provide an airtight seal at the corner of the furnace 158.

FIG. 54 shows a portion of the side bucket 546 shown in FIG. 50, which is attached to a fixture 561 outside the combustion chamber. The side bucket includes pans 562-567 made of a corrosion resistant material such as stainless steel. Fans 562-567 are externally accessible to replenish the water in the side bucket 546. In addition, the bottom of the fan 565 is plugged with a plug 571, so that water can be drained there. In addition, the fan 563 has a floating device 574 so that the water in the barrel can be maintained at a desired water level even for evaporation, leakage, and the like.

As shown in FIGS. 54 and 55, the diaphragms 575 of the fans 562-567 run from side to side. The diaphragm 575 is immersed in the water 576 of the seal 538 of FIG. 55 to prevent the gas in the combustion zone 577 from entering the exterior 578 through the fan. However, the diaphragm 575 leaves the passage 581 without touching the bottom of the pan 564, so that water may enter and exit the portion 582 of the side bucket 546 in which the side edge 556 is submerged. Can be.

The fans 562-567 of FIGS. 50, 54, and 55 may not take a continuous form from end to end of the side bucket 546 for various reasons. First, the fan 583 of the fixed structure 561 cannot continue the fan. Second, the fan cannot be located in section 584 because of the beam 532b supporting the furnace. Since there are no fans in these sections, the water tank 546 takes a U shape with a column 583 and a bottom 587 behind the section 584. Nevertheless, the side bucket 546 provides a continuous groove 582 in which the side edges 556 of the furnace 158 are located (see FIGS. 52 and 53). An airtight structure exists between the bucket 546, the fans 562-567, the pillars 583, the grooves 582, and the diaphragm 575, thereby preventing the leakage of gas from the combustion zone 577 to the exterior 578. do.

Details of the horizontal side seals are shown in FIGS. 55 and 56. The furnace 158 has a fire resistant coating 590. Air is supplied to the waste combusted in the furnace 158 through a tube 591 penetrating through the fireproof coating 590 of the fireproof wall 592. The protrusion 593 of the vertical fire wall 592 faces the inside of the incinerator. The protrusion 593 prevents the waste from being pushed to the center of the furnace and prevents waste from being caught in the gap 596 between the furnace 158 and the fixed ceiling 597. The ceiling 597 also has a fire resistant coating 598. The overburned air is supplied to the waste through the pipe 600 passing through the side wall 599 of the ceiling. The protruding portion 603 of the ceiling 597 is located above the protrusion of the furnace 158. Because of this portion 603, no material, dust, or the like is caught in the gap 596.

Three pulsation furnaces 158a-158c are arranged in a line in FIG. 57. Each furnace has side horizontal water seals 538a-538c, respectively.

The side horizontal water seal 538 of FIG. 58 is similar to that of FIG. 55. Further, a fiber pad 606 is located in the gap 596 between the furnace 158 and the ceiling portion 603. The pad 606 is fixed to both the fire resistant coating 590 and the steel plate 608 of the furnace 158 sidewall 592 by the alloy pin 607. Thus, the fiber pad 606 rubs against the steel plate 609 covering the ceiling portion 603 while moving like the furnace 158. Accordingly, the pad 606 should have a lubricating surface 611 that wears when rubbing against the steel plate 609.

The furnace of FIG. 58 moves perpendicular to the figure. The fiber pad 606 must accommodate horizontal motion. The furnace 158 also has a vertical motion component. To operate properly in this state, the pad 606 must exhibit sufficient flexibility to withstand the compression between the sidewall 592 and the ceiling portion 603. At the same time, the furnace 158 should have sufficient elasticity to expand to fill the same gap even when away from the ceiling 603. The features of the fiber pads 495 and 504 of FIG. 45 apply here as well.

59 shows a fiber pad 613 secured with a pin 614 to the sidewall 592 of the furnace 158. Here, the pad 613 abuts against the lubricating steel sheet 615 in the recess 616 under the refractory coating 610 of the fixing portion 603. As in FIG. 58, a water seal 538 is shown in addition to the pad 613. Depending on the situation, a pad may be sufficient.

FIG. 60 is substantially the same as FIG. 59 except that a bag 618 is placed in the bucket 582 and completely encloses the blade 556. The strip 619 connects the bag 618 to the furnace 158, and the strip 620 connects the bag 618 to the column 583 of the fixture. As with FIG. 48, the bag 618 includes water 576 and pad 613 to triple seal the furnace 158. Depending on the situation, not all of them may be necessary. In particular, without water 576, blade 556 is also unnecessary. The description of the horizontal horizontal sealing part of FIG. 48 also applies to the side horizontal sealing part of this drawing.

61-66 show an example in which a different material 623 is used for a barrel 582 installed in the column 583 of the fixed structure. Dipping the blade 556 into the material 623 creates a horizontal side seal. The material 623 should allow the pulsation of the furnace without harming the keg 582, the blade 556 or the material itself. In addition, the material should be used with other seals, such as fiber pads, bags, to form multiple seals.

However, the material 623 of FIG. 61 takes the form of water 576 described above, and in FIG. 62 the sand 626 contained in the side barrel 582 serves as a sealing material, and in FIG. A fine net 627 is welded to the bottom. Sand 628 lies on mesh 627. Air or other gas entering through tube 631 underneath net 627 may increase the flowability of sand 628 when needed. As described with reference to FIGS. 39-42, air may be introduced continuously or intermittently, or may not be introduced at all. This air provides a positive pressure to prevent the combustion gas from flowing out of the combustion zone of the incinerator, which is the same function as the blower 165 of FIG.

Gravel, alumina, silica, etc. The bubble materials 635,636 shown in FIGS. 64-65 may replace the sand 626,628 of FIGS. 62, 63, respectively. The remaining features are the same.
