Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a garbage incineration system, and particularly to a system that can achieve complete incineration of garbage and avoid secondary pollution.

Approximately 90% of currently commonly used waste disposal methods use the burial method, while only 10%
The current situation is that they are using the incineration method. The disadvantages of the burial method are well known and need not be detailed. When using the incineration method, there are drawbacks such as the use of complicated and expensive incineration equipment, which hinders cost reduction, and the use of equipment that is too simple, which can lead to secondary pollution.

In view of the above drawbacks, the present invention has a simple mechanism,
The aim was to provide a waste incineration system that could prevent the occurrence of secondary pollution.

The main object of the present invention is to provide an incineration system that achieves complete combustion by appropriately treating waste.

Another object of the present invention is to fully recover the amount of heat generated during garbage incineration, thereby preheating and drying unburned garbage, thereby achieving the effect of complete combustion.

Another object of the present invention is to provide a waste incineration system that can remove foul odors and suspended particles from waste gas generated during incineration and emit clean gas free from air pollution.

Another object of the present invention is to provide a waste incineration system in which the suspended particles removed from the waste gas are recovered as they are or mixed with cinders to produce a low-grade fertilizer.

In the garbage incineration system of the present invention, the garbage incineration procedure is divided into three processes: pre-treatment, incineration, and post-treatment.In the pre-treatment, iron and moisture contained in the garbage are first removed and dispersed. After making it easy to incinerate, in the incineration process, the pretreated waste is dried by circulating the flow of high-temperature waste gas generated during incineration, and then incinerated.
In the post-processing process, the high-temperature waste gas generated during the incineration process is led to a flow device, where it is cleaned and deodorized.
The resulting wastewater can be recovered as water fertilizer or mixed with cinders to create a low-grade fertilizer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the garbage incineration system of the present invention will be described below with reference to the accompanying drawings.

As shown in Figures 1 and 2, first, the garbage was put into the hopper 2 using the tilting truck 1, but the hopper 2
The capacity of the tipping truck 1 must be appropriately set depending on the size of the tilting truck 1 and the time interval of its arrival, so as not to interrupt the combustion of the garbage. A pair (two) of dispersing wheels 3 are provided below the hopper 2, and two unhooking wheels 4 are provided. As shown in FIG. 3, on the surfaces of the dispersion ring 3 and the dispersion ring 4, a dispersion ring hook 3a and a dispersion ring locking rod 4a are attached, respectively, so that the dispersion ring hook 3a and the dispersion ring 3a are oriented vertically and The horizontal pitch is appropriately set to allow even long and large metal objects to pass through so as not to cause damage to the dispersion ring hook 3a, and the ejection rod 4a is moved in the direction shown in the figure together with the dispersion ring hook 3a. It is designed to rotate and shred plastic bags, etc.
The dispersion wheels 3 are maintained at an appropriate distance from each other so as to break up large-sized debris and allow metal objects and the like to pass through.

A flat belt and a conveyor 5 are attached to the lower side of the dispersion wheel 3 and the unhooking wheel 4 at an appropriate distance.
Dampers (not shown) are installed on both sides to prevent light garbage from escaping, and the dispersed garbage falls onto the top surface of the flat belt and conveyor 5.
It is conveyed to the underside of the permanent magnet or solenoid 6.

That is, as shown in FIG. 4, a non-magnetic case 7 outside the permanent magnet or solenoid 6 is attached obliquely to the upper side of the belt or conveyor 5, and as shown in FIG. It is designed to absorb iron pieces, etc.

A scraping plate 9 is provided below the magnet 6, and both ends of the scraping plate 9 are fixed to the spiral knife 8a. Screw rods 8 were attached to both sides below the magnet 6, and a vertical tank was provided in the case 8b. Then, as shown in FIG. 5, when the chain (both not shown) is moved by a gear motor, the sprocket 13 rotates in the same direction.
By shifting the helical force 8a from the left to the right, the scraping plate 9 scrapes off the iron pieces that are attracted to the magnet 6 and drops them above the receiving plate 9a.
The scraping plate 9 stops the forward movement of the receiving plate 9a by contacting the stopper 8c.
continues to be transferred to the case 7 of the magnet 6, and when the spiral knife 8a enters the left and right spiral switching tanks (not shown), it stops momentarily, and at this time, the iron piece attracted by the magnetic force Since there is no magnetism, the iron pieces are dropped into the receiving tank 10 together with the iron pieces on the receiving plate 9a, and are concentrated in the collecting tank 11 or the container 12 due to gravity. When the scraping board 9 moves from the right side to the left side, the spiral knife 8a enters into the spiral switching tank on the left side.

Garbage must be dispersed by the dispersion wheel to a length less than G. If the length is longer than this length, use measures such as rolling to keep it below the above length.
It is designed to be easily combusted within a short period of time.

Next, as illustrated in FIG. 6, after being inserted into the feed tank 16 by a flat belt and conveyor 5, the waste is crushed by a roll 17, and with the help of a flywheel 18, the garbage that is not crushed is Since its thickness _G1 is shorter than the above length G,
easily passed. At this time, if there is a piece longer than G, it is crushed by the secondary roll 19 and its maximum thickness G ₂ is maintained at G ₂ <G ₁ <G.

The width of the outlet 21 is the same as that of the feed tank 16 and the rolls 17, 19, and the thickness is the same as _G2 .
As it goes downwards, it changes from a flat shape to an elliptical shape, and then to a two- or three-layered flat shape, and at the exit, its thickness becomes 2G ₂ to 3G ₂ , and its width is the same as the original. It will be one-half or one-third. The power source is the rolls 17 and 19, and the thrust of the tooth-like grooves provided on their surfaces forces the waste to the outlet 21. Although this costs only a small amount, it can significantly save the manufacturing costs of subsequent equipment, and moreover, this means allows the subsequent dewatering operation to be carried out.

After being treated by this means, the waste becomes streaky and is transferred from the outlet 21 to the chain conveyor 22, where it enters the next dewatering process. Since the water content of shredded waste is uneven, the aim is to fully dehydrate it using a dehydrator, prepare it for combustion of organic matter within a short period of time, and save investment and operating costs.

The dehydrator was constructed as illustrated in FIG. In other words, the specially provided chain conveyor 2 includes a support frame 22a, a track 22b, an outer chain plate 22c, an inner chain plate 22d, a roll 22e (small diameter), a transport plate 22f, and a damper 22.
g, screws 22h, and drainage holes 22i.

The streak-shaped garbage coming out of the outlet 21 of the rolling machine is
Along the chain conveyor 22, first dewatering rolls 23 (lower side) and 24 (upper side), second dewatering roll 2
5 (lower side) and 26 (upper side), and is transferred to third dewatering rolls 27 (lower side) and 28 (upper side), and these dewatering rolls have a surface linear velocity that is the same as that of the conveying plate 22f on the chain conveyor 22. The gaps G ₃ , G ₄ , and G ₅ have the following relationship: 2G ₂ > G ₃ > G ₄ > G ₅ > G ₂ Most of the moisture is absorbed by the dry garbage, but some of it flows out along the equipment, so a collection tray is provided below the chain coveyer 22, and the collected moisture is collected through a tray (not shown). , is led to a dirt pond etc. by a pipe.

The lower rolls 23, 25 and 27 are chain
A sprocket 31 is provided below and in contact with the transport plate 22f of the conveyor 22, and for convenience, the same motor (not shown) drives a sprocket 31, and each roll 23, 2 is connected via a chain 32.
It is adapted to transmit power through sprockets 30 of 5 and 27. Further, the idlers 29, 29 are provided to ensure the transmission between the chain 32 and the transmission sprocket 30 of the rolls 25, 27.

The transmission operation of the upper rolls 24, 26 and 28 is as follows:
Since it is the same as that of the lower roll, the explanation will be omitted.

The waste squeezed by the three rolls becomes a strip and is transferred from the outlet 33 to another chain conveyor 34 and enters the saw banding process. In the case of a small-sized combustion device, the waste squeezed in the three-stage roll squeezing process can be directly transferred from the outlet 33 to the scissors 39 and cut.

After being treated in each of the above steps, the waste becomes streak-like material, which has poor ventilation and is difficult to dry and preheat, so it must be cut into pieces. In a large incinerator, if the distance between the dampers 22g in the A-A arrow view of Figure 7 is too large, the material is cut into narrow strips using a saw band device prior to shredding, and then shredded into small strips. There must be.

The sawing and cutting operations are performed as shown in FIG. In other words, the waste is transferred to the feed port 33 (this port is also the exit of the previous stage, so it is transferred to the chain conveyor 34 and enters the sawing and cutting operations. It has the same configuration as the conveyor 22, and except for the reference numeral of the transport plate being changed from 22f to 34f, all other parts are the same, so a description thereof will be omitted.

The transport plate 34a is provided with several concave tanks,
Several circular saw bands are attached to the circular saw machine 35, and a protective frame 37 is attached to the outside thereof. The holding plate 36 suppresses dust by the elastic force of a spring 38 so as not to interfere with the operation of the motor 35a and the circular saw machine 35. In the case of small incinerators, the saw band device may be omitted altogether.

The cutting shears 41 are similar to existing commercial products, but the differences are as follows:
9 is kept at an appropriate distance from the outlet on the upper side of the chain conveyor 34, and is used for buffering. The upper scissors 42 are used to cut dirt in cooperation with the lower scissors 43, and the gap between the two is designed to be as narrow as possible. This is so that even thin plastic bags can be easily cut.
At the start of cutting, the workpiece is first held down by the presser plate 46, the workpiece is cut by the upward movement of the upper scissors 42, and then the workpiece 44 is continuously cut with the help of the rollers 40. The workpiece 44 is then returned to the position shown in FIG.

After that, it is transferred to a drying room several times to ten times as wide as the chain conveyor 34, and placed in the storage tank 101 in front of the drying room 103 (storage tank 101
The width of the drying chamber 103 is the same as the width of the drying chamber 103).

The configuration of the dispensing device is as shown in FIG. That is, the distribution board 48 is attached to a fixed pin 49 so as to be able to move left and right, the motor 52 rotates the turntable 51 via the transmission case 53, and the rotation pin 50 is attached to the outer edge of the turntable 51. One end thereof is fixed to the turntable 51, and the other end is inserted into the guide tank 54. The guide tank 54 is attached to the center line of the distribution board 48 at an appropriate location. When the rotation pin 50 performs a circumferential movement together with the turntable, the guide tank 54 is also rotated accordingly, swinging the distribution plate 48 from side to side and distributing the workpiece 44 to the storage tank 101. do.

This completes the preparatory operations before incineration.

The contents of garbage vary; there are items with a high calorific value such as rags with oil adhesion, and items with a moderate calorific value such as bamboo, wood, clothing, and plastic products, as well as waste paper, vegetables, etc. Some have low calorific value. The moisture content of these wastes after being processed in each of the above steps is approximately 12% to 18%, of which plastic products occupy a low proportion in terms of weight, but in terms of volume, they account for a considerable amount. It accounts for a large percentage. Moreover, since its melting point is low, when it is heated, it turns into a liquid and becomes sintered coal mixed with other types of garbage, so it is not easy to oxidize in a short period of time, and at the same time, it is difficult to dry. Even during the process, since the workpiece 44 is made into one piece, there is a risk that ventilation will be adversely affected, so a solution must be taken.

Thus, in order to avoid problems with the melting point of plastics and the use of expensive heat-resistant steel materials, it is generally desirable to dry at low temperatures.

The drying and preheating operations are as shown in FIG. That is, the workpiece 44 after being cut is uniformly distributed onto the storage tank 101 by the distribution board 48, and this storage tank 101 has an adjustment port 102,
Transport chain, shelf 104, case case 124
and firebrick walls 123 on both the left and right sides.

The rotation of the motor 116 causes the transmission sprocket 1 to move through the transmission case 115.
14 is driven, the main drive shaft and the sprocket 113 above it are rotated, and the chain and shelf 10 are rotated.
4 gradually forward, and the driven shaft and sprocket 112 are also moved. Due to the blocking effect of the adjustment port 102, the drying chamber (upper layer) 103
The thickness of the workpiece 44 entering the workpiece is kept uniform.

The drying rooms include an upper drying room 103 and a lower drying room 12.
The upper drying chamber 103 is divided into two parts, and the top side, both sides, and rear side of the upper drying chamber 103 are all composed of firebrick walls 123.
The previous example is the preheating chamber 105, and the workpiece 4 below it.

The wind turbine device includes a wind turbine 1 as shown in FIG.
07, transmission belt 108, motor 109, gas introduction manifold 111, air port 124a, hood 110
It consists of

The preheating chamber 105 includes a lower feed port 105a, a bottom layer, refractory brick walls 123 formed on both left and right sides or the upper end of the top surface, and a steam super heater (steam super heater).
The lower feed port 105a is made of heat-resistant and wear-resistant steel, and since the temperature thereof is relatively high, cooling water is passed between the feed ports 106 and 106. All workpieces 44 are introduced from here into the preheating chamber 105.

Hot air rises from the combustion chamber 126 and steam generator 1

6, the hot air from the hot air pipe 140 (see FIG. 12) passes through the fire pipe 127a to generate steam, and passes through the fire pipe in the steam super heater 106 to improve the dryness of the steam. Thereafter, it further rises and enters the upper drying chamber 103 through the damper 151. Under steady-state conditions (i.e. workpiece 4
4), air expansion PV
The opening degree of the damper 151 is adjusted according to the relational expression T, and the moisture in the workpiece 44 is evaporated so that the temperature of the exhaust gas entering the upper drying chamber falls within the required range. At this time, the volume of the workpiece 44 gradually increases (without affecting ventilation), and then the hot air enters the lower drying chamber 122 through the ventilation hole 104-8 of the shelf, and is sucked into the windmill 107. , and sent to the hood 110. In addition, in order to maintain good ventilation, the drying room 1
The width of 03 is set slightly larger. Since the hot air is blown from above to below, the workpiece 44 is blown through the ventilation hole 10.

There is a possibility that it will fall during the 22nd. At this time, since the lower half of the case 124 was provided diagonally toward the center,
The fallen workpiece 44 is collected in a central tank,

It is equipped with a water supply pump, etc.

After the workpiece 44 has been dried, it enters the preheating chamber 105 while its volume gradually increases, and when it enters the preheating chamber 105, those that are easily combustible are first ignited, and after being dropped into the chain grate stocker 125, With the help of primary air from hood 132 and air from secondary air gate 138, the thickness of workpiece 44 on check grate stocker 125 becomes thinner and thinner as it is combusted generally into combustion chamber 126. In the end, only materials that are difficult to oxidize, such as sintered coal, bones, and meat, are left behind. These wastes are discharged directly to the ash truck 206 via the outlet 139.

The combustion chamber 126 is divided into two parts, with a water wall 127b above the steam generator 127 as a demarcation point, the front part being a pre-combustion chamber, and the rear part being a post-combustion chamber. The hot air from the pre-combustion chamber passes through the hot water wall 127
b, steam pipe 128, steam super heater 1
The workpiece 44 is heated through the outer layer of 06 and enters the upper layer drying chamber 103 from the preheating chamber 105. The hot air from the post-combustion chamber heats the lower layer of the steam generator 127, the outer layer of the water wall 127b, and later mixes with secondary air, enters the fire pipe 127a, and passes through the fire pipe 106a of the steam super heater 106 to the damper. It enters the upper combustion chamber 103 through 151.

After the sintered coal in the ash transport vehicle 206 is oxidized by the blower 241, the exhaust gas is transferred from the hot air pipe cap 240 and the hot air pipe 140 to the fire pipe 127a.
After entering the steam super heater 1
From the fire pipe 106a of No. 06, it enters the upper drying chamber 103 through the damper 151. The ash transport vehicle 206 connected to the combustion chamber 126 is the first vehicle, but after it is fully loaded, it automatically moves forward and becomes the second vehicle, and then advances further and gradually becomes the third vehicle, the fourth vehicle, and the fifth vehicle. . The first wheel and the second wheel can be considered part of the combustion chamber 126.

The gas produced when the organic charcoal in garbage is burned is mostly odorous, so if it were released directly into the atmosphere, it would pollute the air. Therefore, the gas oxidized in the ash transport vehicle 206 is
After passing through the hot air pipes 240 and 140, the fire pipe 127a,
Enter the drying chambers 103 and 122, and then enter the windmill 10.
After the dust is transferred to a dust washing/dust collector through a filter 7 and treated, it is released into the atmosphere.

Most of the equipment components used for combustion can be selected from commercially available products. For example, the grate stocker 125, steam generator 127, etc. can all be used with slight modifications as shown in the figure, so a detailed description of their structures will be omitted. In addition, please refer to FIG. 14 for the ash transport vehicle 206.

As mentioned above, the contents of garbage vary widely, and their calorific values also vary widely.
It is obvious that in order to effectively incinerate this, temperature control is extremely important. In other words, temperature control is a key point in ensuring smooth incineration operations at factories.

As shown in FIG. 13, the temperature facilities used during drying include a thermometer 150, a damper 151, a vacuum meter 157, and a burner 1 as a starting and heating device.
52 (burner), blower 153, hot air pipe 15
4. It is composed of a motor 155, a support frame, etc., and also includes a secondary air gate 138, a blower 241, a variable speed motor 135 of a chain grate stocker, etc.

First, the upper and lower temperature limits of the pointer of the thermometer 150 must be set. As a method for this, the maximum temperature of the workpiece 44 in the upper drying chamber 103 must be lower than the minimum melting point of the plastic bag, so the temperature obtained by adding this temperature difference to the temperature of the thermometer is set as the upper limit temperature. In addition, the lower limit temperature can be set after taking into consideration all relevant factors such as the average moisture content, specific heat, thickness, advancing speed, length, width, and hot air volume of the workpiece 44. good.

If the temperature of the thermometer tends to approach the upper limit temperature, the secondary air gate 138 is opened wide (controlled by a forward/reverse deceleration motor and wire, not shown), and if this also causes a temperature drop effect. If not,
The next method is to
42, and if this is still not effective, decelerate the blower 241 or accelerate the variable speed motor 135, or if the temperature still cannot be stopped from increasing, close the damper. By gradually decreasing the degree of opening of 151 and increasing the degree of vacuum in the drying chamber, the temperature will naturally decrease.

On the other hand, if the temperature tends to drop close to the lower limit of the thermometer, first reduce the air volume in the secondary air gate, and if this is still ineffective, , take measures such as accelerating the blower of the first ash transport vehicle 206 and opening the wind blocking gate 242, and if these are still ineffective,
If the rotational speed of the variable speed motor 135 is reduced, but the effect is still not obtained, the damper 151 may be completely opened.

The fire extinguishing procedure is as follows. That is,
1. Reduce the degree of opening of the secondary air gate 138. 2.Stop the drying motor. 3. Either the workpiece 44 in the combustion chamber 126 is completely burned or the ash transport vehicle 206
Transport it inside. 4. Stop the motor 131 of the primary wind turbine. 5. Stop the grate stocker motor 135 and stop the blower motor 241.
6. Fully close the secondary air gate 138. 7. Close the wind blocking gates 242 and 247, and as shown in Figure 16, store the seeds of the fire in the sintered coal of each ash carrier 206 in preparation for tomorrow's ignition. 8. Stop the water supply pump 134. 9. Adjust the opening of the damper 151 to the position shown in the diagram to prepare for tomorrow's ignition.

The procedure for starting a fire is as follows. In other words, 1.
The blowers 241 of the first and second ash carriers are started, and the wind blocking gate 242 is started. 2. Start the starting device, that is, start the burner 152 and blower 153. 3. Increase the temperature of the thermometer 150 by several degrees (this means that the workpiece 44 in the drying chamber 103 has ignited and reached the lower limit temperature, and at the same time the steam pressure has reached half of the predetermined pressure) ). 4. Start motors 135, 131 and 116 one after another. 5. Open the secondary air gate 138 appropriately. 6. Open the wind blocking gate 247. 7. Open the water supply pump 134. 8. Adjust the position of damper 151.

All of the above-mentioned operations such as temperature control, extinguishing, and ignition can be fully automated and controlled by a computer.

If garbage is left as it is after incineration, it will cause secondary pollution, but if it is properly disposed of, the cost required will be enormous, so it is possible to generate electricity using the thermal energy generated during garbage combustion. A proposal has been made to use this method, but the fact is that small generators using this method are expensive and therefore not economical. Therefore, if the thermal energy generated during garbage incineration can be used to reduce investment in incineration equipment and save electricity, saving electricity will have the same effect as generating electricity. At the same time, the thermal energy can be used to remove water and air pollution, or to mix the burnt ash with concentrated wastewater to make compost.

If combustion coal is not properly disposed of, it not only leads to loss of thermal energy, but also poses a serious pollution problem.

Regarding the ash transport vehicle to solve this problem, the first
This will be explained with reference to Figure 4.

The ash transport vehicle includes a chassis 201, wheels 202, axles 203, bumpers and pads 204, a safety lever 205, a car body 206, a casing 207, a refractory brick 208, a hinge 209, an active bottom cover 210, a fire rod 211, a stopper pin 212, and a tension spring. 21
3. It consisted of a wind gate 214, a thrust hook pad 215, etc.

Its special features are the bottom cover 210 and the flange 211.
are integrally connected, one end of which is connected to the hinge 20.
9 is fixed to the tubular iron at the lower end of the casing 207, the other end is supported by a stopper pin 212 installed between the chassis 201 and the vehicle body 206, and is brought close to the chassis 201 by the elastic force of a tension spring 213. energized.

When the ash truck 206 is pushed up to the switching frame 260, the stopper pin 212 is pushed out by the piston of the cylinder 264 (installed diagonally) attached to the track bracket 261 on the switching frame 260.
The active bottom cover 210 and the fire rod 211 can fall under their own weight, and all the garbage can also be knocked down (see Figure 17).

The movement trajectory of the ash truck is as shown in Figure 15.

The inner track is a parking track for the ash transport vehicle 206, as shown in the AA arrow view, and the outer track is a return track, as shown in the B-B arrow view.

The inner track has a horizontal rail 22 as shown.
3. Inclined rail 224, horizontal rail 22 at the other end
8,229, stopper 230, chain groove 22
7. It was composed of the horizontal line 235 of the highest horizontal rail, the center line 236 of the combustion chamber, etc.

In the chain groove 227, the roller chain 22
5 is attached to the roller chain 225,
By providing thrust hooks 232 at intervals of 1.05L, the ash transport vehicle can be moved between the thrust hooks 21 on the chassis.
It is pushed so as to come into contact with 5. Horizontal chain rail 222, inclined chain rail 22
4 are all parallel to the ash transport vehicle, and have a main drive sprocket 221 and a deceleration motor 220 (with brake).
and a driven sprocket 226.

As shown in the BB arrow view, the outer track is composed of an inclined rail 231, a branch part 237, etc.
It is used as a return orbit.

When the ash truck stopped at the center line 236 is fully loaded with sintered coal, the sintered coal outlet 139 becomes V-shaped in response to a signal from the timer, and the sintered coal exit 139 becomes V-shaped during the period of ash truck movement. The charcoal is stored in this V-shaped outlet, and the roller chain 255 is moved forward by a distance of 1.05L by the start of the motor 220, and then automatically stopped. At the same time as the blocking gate 243 is closed, the blocking gate 24
2 (see Figure 16).

The above operation can be achieved using only a timer, micro switch, and magnetic switch, so an expensive computer is not required and costs can be reduced.

Ash truck 2 approaching leading sprocket 221
After 06 is pulled up to the horizontal rail 223 by the driving hook 232, it separates from the chain 225, and due to its inertia, it automatically moves to the switching frame until it comes into contact with the cylinder 265 with the scissor-shaped clip. This allows the cylinder 265 to be locked. All subsequent operations are controlled by microswitches, magnetic switches, solenoids, etc.

Waste materials that are difficult to burn, such as sintered coal, bones, and meat, are transported from the combustion chamber 126 to the ash truck 206 through the outlet 139, and then the wind from the blower 241 is passed through the wind gate 214 of the ash truck to the furnace 211. By passing it through the upper layer, the oxidation is accelerated, and the hot air released from there is passed through the hot air pipe and its cap 24.
0 and returns to the combustion chamber 126.

After the ash transport vehicle 206 is fully loaded with sintered coal, it automatically moves forward and transports the 2nd, 3rd, 4th, etc.
As the car transforms into the fifth car, each blower 241 also gradually reduces its air volume, and dustproof nets 249 are installed below the protective caps and their pipes 244 from the second car to the fifth car. , dust, etc.
This prevents the ash from being discharged into the atmosphere and polluting the air while being transferred from the ash transport vehicle 206 to the collision site.

When the combustion coal in the second ash transport vehicle started to oxidize, the organic matter that had flowed in from the combustion chamber 126 was present in its top layer, so the hot air was sent from the hot air manifold 245 through the baffle gate 242 to the hot air pipe 240. Than,
By introducing the organic matter into the combustion chamber 126, all organic matter is oxidized after a certain period of time. Then, according to the timer signal, the motor 252
When is automatically reversely rotated, the wire ring 253
At the same time as the wind blocking gate 243 is raised, the wind blocking gate 242 is raised.
, the hot air from the second ash carrier 206 is combined with the hot air from the third, fourth, and fifth ash carriers, and then the hot air is transferred from the hot air manifold 245 to the general pipe 2.
46 and further led to the hot air duct 248. The inside of the hot air duct 248 is divided into several layers, and in the illustrated case, one layer is for hot air, and the other layer is for waste gas and hot gas coming from the dust washers and dust collectors 302 and 306 and their outlet 308. The waste gas is mixed in the upper part to raise the overall temperature and then guided to the chimney 254.The higher the temperature, the lower the chimney 254 is used, so each pipe is added with a heat insulating agent. And the inside of the chimney 254 is made of firebrick 255
must be established. The total blocking gate is 247
By being closed after garbage incineration, the charcoal in the second to fifth ash transport vehicles 206 is not continuously oxidized and is prepared for tomorrow's ignition.

Further, as shown in FIG. 17, the switching frame 260 is arranged such that the bumper and pad 204 of the ash truck are brought into contact with the cylinder 265 with the scissor-shaped clip fixed on the fixed frame 274 due to inertia. When pushed to the upper rail 271, the contact of the micro switch is closed,
Passing a current causes a solenoid (not shown) to open and cause the piston 265- of the cylinder to open.
1 inward, and the link 265-2 is deformed into an inverted V-shape to form the scissor-shaped clip 265-2.
3, the piston 265-1 is continuously retracted inward while sandwiching the bumper and pad 204, thereby firmly holding the entire ash transport vehicle 206. This leaves the ash truck 206 unmoved during each subsequent operation.

At this time, the wheels of the ash carrier 206 contact another microswitch, and the cylinder 264 on the track bracket 261 pushes open the stopper pin 212 on the ash carrier 206, thereby opening the active bottom cover 21.
0 falls using the hinge 209 as a fulcrum, knocking down all the waste inside the car, and releasing the fountain shower 27.
High-pressure water is ejected from 0.270 m to prevent dust from scattering.

After the cylinder 264 pushes open the stopper pin 212, it automatically returns to its original state, but after the active bottom cover 210 falls, the buffer action of the buffer spring 268 causes the switching frame support mechanism 262 and/or ) Collision with the longitudinal track 234 is prevented. Thereafter, the fountain shower 270, 270 stops the fountain, and the cylinder 26
The piston 6 is located at the piston fulcrum 2 on the bottom cover 210.
17 and returns the bottom cover 210 to its original position above. At this time, the cylinder 266 rotates together with its fixing point 266a, so the wire 267 whose one end is fixed on the cylinder 266 also rotates with the rotation. Then, the weight 267d is lowered along the guide plate 267e via pulleys 267a and 267b, and when the bottom cover 210 presses the stopper pin 212 and returns to its original state, the cylinder 266 has reached the dead point, so the micro switch (Fig. (not shown) starts to operate, and by reversing the cylinder 266, the piston is retracted inward, separating from the fulcrum 217, and the entire cylinder 266 is quickly lowered, and at this time, the weight 267d is attached. Therefore, the descending speed is safe, and when the weight 267d reaches the initial position, it comes into contact with the spring 267c, so the upward impact force of the weight 267d is absorbed, which means that the restoring force of the cylinder and the lowering of the bottom cover 21c The impact force caused by the above is reduced by the spring 267c. with this,
This completes the tilting motion of the dust.

At this time, the 2
63 pushes out its piston, advances the wheel 273 on the switching frame 260, and moves the wheel 272 to the other side along the track 234, while the axle 273 is a cylinder fixed on the lower fixed frame 269. 263, and by pushing out its piston 265-1, the cylinder 265 pushes the ash truck 206 onto the outer track 231, moves it to the stopper 230, and then closes the safety lever 205.
After colliding with the cylinder, the force of the cylinder (not shown) pushes the branch 237 away, and the reaction force causes
The ash truck 206 is moved in the opposite direction, and due to its inertia, the driving hook pad 215 on the chassis exceeds the height above the driving hook 232 on the roller chain 226 and collides with the first ash truck 206. and stop.
At the same time, the branch portion 237 returns to its original state, and one cycle of operation of the ash transport vehicle 206 is thus completed (see FIG. 15).

Then, the ash transport vehicle 206
60, the action of the timer activates a cylinder fixed on the lower fixed frame 269, which pushes out its scissor-shaped clip and causes the switching frame 260 to return and be fixed onto the upper fixed frame 269. This completes the series of circulation operations for tilting the ash.

Next, with reference to FIG. 19, the configuration of the dust washing and collecting device will be described as follows.

The dust washing and dust collecting device includes a casing 302, a dust washer 303 (including a dust washing pipe 303-1, an end plate 303-2, and a water launch hole 303-3), a circulating water pipe 304, a water pipe 305, a tank water pipe 305a, and a dust collector. Cum dust cleaning net 30
6, filter 307, exhaust port 308, drain pipe 3
09, a water tank 310, etc.

After the waste gas is advanced to the hood 110 by the wind turbine 107, it is passed through the inlet port 301 to the casing 30.
2 into the dust washer. At this time,
Since the cross-sectional area of the dust washer is several times that of the inlet port 301, the speed at which the waste gas is introduced is also greatly reduced, and the flow from the dust washer 303 to the dust pipe 303-1 is greatly reduced.
and further from the circulating water pipe 304 to the launching hole 30.
The high-pressure circulating water that entered 3-3 opens the launch hole 303.
-The waste gas is also rotated in the right-hand thread direction by the circulating water that has three to four right-hand threads, and as the water and waste gas are sufficiently mixed, various oxides in the waste gas are removed. The gas temperature also decreases, and when it comes to the dust cleaning pipe 303-1, the flow rate is significantly reduced, and furthermore, the dust collection and cleaning net 306
You can proceed to This net is made of a corrosion-resistant material, with several layers of fiber mat sandwiched between them, and above is a water supply pipe 305a, and the net is sandwiched between the grooves of this pipe. Fresh water flows from the water pipe 305 through the grooved water pipe 305a along the screen and the mat, and the thin and light dust that is absorbed by the wind turbine 107 is washed away from the screen, while the dirt contained in the waste gas is removed by the screen mat. The net mats are washed with clean water and kept clean at all times. If a single dust collection and cleaning device 306 cannot purify the waste gas, it can be installed in several layers to collect and purify the steam. Furthermore, a large amount of steam and water droplets in the gas are removed by the secondary filter 3.
07, the structure of this filter is the same as that of the above-mentioned mesh mat, and when water drops pass through, they adhere to this filter and drain into the water tank 310 and the drain pipe 30.
9 and is discharged. The waste gas after the treatment is clean, contains little moisture, and has a low temperature, so it is difficult to discharge it, so heating is required.

There are two sources of waste water, one is waste water in a specially designed chain and a water tray below the conveyor 22, which is led out from pipe 332, and the other is a drain pipe of the dust washer and dust collector. This is derived from No. 309. The amount of the former is small, but the amount of the latter is relatively large. If these wastewaters are left in the outside world, they will contaminate water sources. If this is treated using a general sewage treatment method,
This is not a desirable method because the investment cost would be enormous. Therefore, the most advantageous method is
Use steam to condense dirt into water fertilizer, use ash transport truck 20
One method is to mix it into the ash that has been felled from No. 6 and use it as compost.

As shown in FIG. 20, the wastewater treatment system includes a circulating water pond 320, a fresh water pond 321, a sewage pond 322, a sewage steam pipe 323, a fresh water pipe 324, a high pressure water pump 325, switches 326, 327, 328,
and 329, communication pipe 330, sewage pipe 33
1 and 332, filtration net 333, drainage pipe 33
4, saturated steam pipe 129, condensed water pipe 13
3. It is composed of the circulating water pipe 304, fresh water pipe 305, drainage pipe, etc.

The sewage in the dust collector and washer 302 is drained from the drain pipe 3.
From 09 onwards, after lightweight and fine dust is removed by the filtration net 333, the drain pipe 334 and switch 3
28 into the circulating water pond 320, and the high pressure water pump 325 connects the circulating water pipe 304 to the dust washing pipe 3.
02, where it is washed with dust, and then flows into a circulating water pond 320 through a drainage pipe 309, where it is circulated. At this time, the circulating water gradually increases. This is because, in addition to the water from the clean water pipe 305, some of the water vapor contained in the exhaust gas also becomes water after its temperature is lowered by water washing. After repeating the circulation several times, the filth absorbed into the water gradually increases, the concentration of the water also increases, and when the amount of water in the circulating water pond 320 reaches its upper limit, the switch 329 By opening the switch 328 and closing the switch 328, when the amount of water in the circulating water pond 320 reaches the lower limit, the switches 326 and 328 are opened for the first time, and the switch 328 is closed.
29 is closed, and after the amount of water in the circulating water pond 320 reaches the level required for circulation, the switch 3 is closed.
26 is closed. At this time, to Shimizu Pond 321,
Well water or tap water must be replenished until the water level is full.

Both the circulating water from the communication pipe and the sewage from the sewage pipe 332 are transferred from the sewage pipe to the sewage pond 32.
2, when the water level reaches the upper limit, the switch 129b of the saturated steam pipe 129 is opened to accelerate the evaporation of the waste water, and after the steam in the steam pipe 129 enters the waste water pond 322, the condensed water is From the condensed water pipe, it is introduced into the steam generator 127 by a water pump.

After the sewage in the sewage pond 322 is heated with saturated steam, a large amount of water vapor is generated, and this water vapor is produced from the sewage and has a bad odor, and cannot be released to the outside world as it is. Therefore, the waste water is collected in the steam pipe 323, led to the fresh water pond 321, cooled, and turned into waste water condensed water, which is led to another pond (not shown), and from its components,
By selecting and adding chemicals, the water becomes neutral and can be reused. On the other hand, the temperature of the water in the fresh water pond 321 rises due to passing through the sewage vapor, so the water temperature is lowered by connecting a radiator to the fresh water pond, and then the water is circulated to the circulating water pond or the fresh water pond. .

When the water level in the sewage pond 322 reaches the lower limit due to evaporation, the saturated steam switch 129b is immediately closed. At the same time,
The wastewater after concentration can be discharged from the switch 327, and it can be made into water fertilizer by sampling it and selecting and adding chemicals from its components, or it can be mixed into ash to be made into compost. Because it can be done, the effect is great.
