1228581 V. Description of the invention (1) Field of invention The present invention relates to incinerators and incinerators for incinerators for incineration of household waste and various industrial wastes, and particularly relates to the treatment of grasses, paper scraps, cloth scraps, and synthetic resins. Incinerators and incinerators for incineration of waste, polymer waste, kitchen waste, etc. Known technology Regarding this type of incinerator used conventionally, I am familiar with the incinerator shown in Fig. 7. The combustion gas outlet side of the primary combustion chamber 101 of this incinerator (A,) is provided with a diffusing pipe 1 51, and the diffusing pipe is provided with an injection port 15 2 to inject air for primary combustion 1 6 1. Also, a side burner 106 of the incinerator (A ') is provided with a burner burner 110 to perform primary burner combustion in the burner burner 116. In this auxiliary burner 110, a cooling device (not shown) for cooling the auxiliary burner 110 is attached to prevent the thermal damage of the aforementioned auxiliary burner 110. This auxiliary burner 110 is cooled by injecting the cooling air together with the flame (F,). In the same figure, 105a and 105b each indicate the inlet of the incinerated 160 and its closing door. Further, '102 is a secondary combustion chamber, and 107a is an opening for an exhaust gas 165 outlet. In this incinerator (A,), the primary combustion air 1 6 1 faces the combustion gas 1 62 flowing toward the combustion gas outlet opening 1 09a, and the injection port 1 5 2 of the diffuser pipe 1 5 1 faces the Incineration of 160 spray. Next, the primary combustion air 1 6 1 is blown to the incinerated material 16 0 and burned, and then becomes combustion gas 162 and is switched to a direction opposite to the original injection direction (that is, reversed), and flows to the outlet opening 109 a. . Next, this combustion gas 162 flows into the secondary combustion chamber 102 from the outlet opening 109a. Here, the combustion gas 162

1228581 V. Description of the invention (2) The body is burned by a flame from a secondary burner (not shown) (secondary combustion), and the fumes contained in this combustion gas are removed to make it smokeless. Then, the exhaust gas 165 is sucked into the exhaust gas outlet opening 107a, and then flows to an exhaust gas purification device (not shown). However, in the above-mentioned conventional incinerator (A '), the auxiliary burner 110 is set on the side wall 106 of the incinerator (A,). Therefore, if this auxiliary burner 110 is adopted, the incineration is performed. The combustion-supporting flame (F ') of 160 and the cooling air for cooling the combustion-assisting device 110 are oriented approximately perpendicular to the primary combustion air 161 sprayed from the injection port 152 of the diffuser pipe 151. Being sprayed. As a result, the air flow of the primary combustion air 16 1 and the combustion gas 16 2 in the primary combustion chamber 101 is affected by the flame (F ') or the jet pressure of the cooling air to cause a disturbance, resulting in a primary The flow of the combustion air 1 6 1 and the combustion gas 16 2 is shifted. In this way, the incombustible portion is caused in the incinerated 160, and a large amount of unburned material remains in the incinerated 160, which is a technical difficulty. In addition, the auxiliary combustion burner 110 must be additionally provided with a cooling device to cool the auxiliary combustion burner 110, which complicates the structure of the auxiliary combustion burner 丨 丨 〇, as a result, the manufacturing cost of the incinerator (A ') is increased, and the incinerator is increased. (A,) is not easy to maintain, which is also a technical difficulty. The present invention was proposed by the present invention in order to solve the above-mentioned shortcomings, and its purpose is to provide an incinerator with good combustion efficiency and economy, and in particular, it can completely burn the incinerated material, which can not only reduce unburned materials, but also make dioxin An incinerator with a reduced amount of other harmful gas components and a simple structure, and a combustion supporting device suitable for the incinerator.

1228581 V. Description of the invention (3) In order to achieve the interior of the invention described later, in the burner port, this jet of gas is injected to inject the characteristics characterized by the dispersion and the incineration in the combustion chamber burning in this opening. If the combustion incineration in this specification is reversed for the purpose of turning the combustion type air in one direction to the opposite side, the combustion incineration in this specification, and the downstream conditions, the burning type incinerator is longer than using the forward application type. The incinerator of the invention 1 is provided with a diffuser at the combustion outlet side, the diffuser is provided with air that ejects the combustion gas toward the opening for the combustion gas outlet; the above-mentioned burned gas port is used for combustion: The combustion gas is incinerated and its combustion direction is used (that is, the incinerator is used to explain the flow of the incinerator for the convenience of the furnace.) The combustion is used for air combustion combustion. In other words, the flow combustion is provided with a spray of assisting gas. The "°" is explained in another state, and the gas is burned in the air of the incinerator according to the original. The firing direction of the combustion incinerator is opposite to the air. (It becomes ignited), and in addition, there is a case where the combustion chamber is burned with an empty furnace when the incineration chamber is burned, and the fire is the same gas system, and the combustion gas flows out to a structure. The incinerator pre-constructed smelting furnace reversed and stagnated and was trapped within the two. Therefore, the direction of flame spray. The incinerator with the burning air turned to the combustion gas pipe is converted into an opening for the mouth. The incinerator uses the combustion incinerator, which is called from the diffuser to the exit furnace for a long time. The incineration is based on the direction of this issue. The exit orifice is directed toward the ejected side. It is called "anti-combustion method in this article, and it is" the downstream nozzle. The opening flow is equal to the downstream combustion.

1228581 V. Description of the invention (4) Furnace can effectively incinerate the incineration. On the other hand, the setting of the spraying direction of the flame of incineration is the same as that of the burning air. In addition, the disturbance of the pressure of the jet stream used for combustion burns almost completely in the incinerator, so the amount of unburned material is reduced. Furthermore, since the combustion-supporting combustion is sprayed through the injection port of the gas pipe circulating in the diffuser pipe, a cooling device is attached to the combustion-supporting burner to simplify the manufacturing cost of the combustion-supporting device in the incinerator, and the incinerator is of course reduced. In this incinerator, the diffuser pipe contains the flow direction of the air for injection and goes out of the aforementioned direction. Therefore, when it is in the combustion port of the combustion chamber, it will be injected by the diffuser pipe or the burner burner fire port. The fire reduces the amount of smoke and harmful gas components contained in the aforementioned combustion gas. In the above incinerator, it is preferable to be in the aforesaid diffuser pipe. At this time, in the furnace, the flame of the burner assists the burner to be injected by the diffuser nozzle. Therefore, the flame is burned along the air and combustion The gas does not flow in the flame combustion chamber. As a result, the state remaining in the incinerated material can be attached to the diffuser pipe, which can be used to cool the combustion combustion air, or to cool the diffused air. Therefore, it is not necessary to cool the auxiliary burner, so it is constructed, and as a result, the incinerator can be easily maintained. 'Because the injection port is provided on the combustion gas outlet side to inject combustion air, the combustion gas phase body flowing through the opening for the combustion port is sucked into the fresh combustion air injected from the opening for the combustion gas outlet, and the flame comes into contact and burns. Not only can the gas be reduced, but even the situation such as dioxin is to set the aforementioned burner to actually cool the burner.

J22858 V. Description of the invention (13) Although combustion-supporting fuels can be used, the best case is to use them without limiting their kind of liquid fuel. Special gas fuel or oil, etc. This combustion-supporting fuel supply pipe 27 is for adjusting the flow of the combustion-supporting fuel through the outside side of the release 51 (not shown). The valve 26 in the ten machine is connected to the fuel tank 4 ::? !! 10 is equipped with an ignition device 12 to make the combustion-supporting fuel supplied by the combustion-supporting fuel supply Lu 27 as follows: inside the fire port u of the combustion-supporting burner 10; . The discharge electrode 13 is connected to the "lead wire 15" extended from the connection terminal for the discharge electrode, which is installed in the upper 5 lc. The connection of the "ignition device 12" is made by the aforementioned ignition device 12, A discharge is generated at the discharge electrode 13 and the combustion assisting 7 and the burner 10 are provided with a flame inspection device 18: This flame inspection table is set to 1 to 8 to check whether there is a flame assist from the burner. The structure of the second inspection device 18 is as follows.敎 = 19 near the front side of the fire port u to measure the temperature of the flame ⑺). The thermocouple 19 is connected to: a wire 22 extending from the connection terminal 21 of the thermocouple on the upper plate 51c of the clothesman.

If it is judged that there is no flame (F1), then borrow it. Page 18 1228581

The control device 25 automatically closes the valve 26 and then explains that it has the above structure. First, after the incineration 60 is taken from the inside, the door 5 b is closed to close the door. Then, the valve 2 6 is opened and supplied to the ignition device 1 2 Turn the combustion support 16 to "ON" so that the discharge fuel is ignited and produced by the fire port 11. Then, the flame of the combustion fuel (F1) is increased, and the injection port 5 2 of the tube 5 1 will be burned and incinerated at the same time. 6 0 spray. In this way, due to the pressure of the jet stream of gas 61, it is sprayed with a strong fire port 11. On the other hand, the influence of the jet stream pressure of the aforementioned flame (F1) is burnt by the incinerator 60 because it has accepted this 61, and this is performed. When the incinerated 61 reaches a temperature that can be spontaneously combusted (for example, when the supply of combustion-supporting fuel is stopped and the primary combustion air 61 is injected for combustion, the diffuser 5 1 air 61 is blown to the incinerated 60 to use air 61 Reaching 6 to 1 of the incinerated 60 becomes the operation of the incinerator (A1) which is closed by the incinerated 60. The inlet 5 a is input to the primary combustion chamber i and the inlet 5 a 〇 should be a predetermined amount of combustion-supporting fuel. The fuel is ignited by the state. That is, the ignition open electrode 13 is discharged to assist the combustion to generate a flame (F 1). The supply amount is caused to be ejected from the fire port 11 and the blower 55 is started to be used for diffusing The flame (F 1) of the air 6 1 into the primary combustion chamber J is diffused toward the incinerator 60 while being diffused by the primary combustion air. The primary combustion air 61 is sprayed toward the incinerator 60 without receiving fire. The flame (F 1) and the primary combustion air 60 assist the combustion. The, when incinerated, such as from about 8 0 0 ° C), the valve 26 is about to close the flame (F 1) elimination. Thereafter, the incinerated 60 was burned in a maintained state. The primary combustion ejected from the injection port is ignited. Next, after the primary combustion position, the combustion gas is generated by burning the air with this primary combustion

Page 19 1228581 V. Description of Invention (15) 62. Thereafter, the injection direction of this combustion gas 62 at the front inlet 5a is closed in the opposite direction (moving. In addition, the outlet opening for the primary combustion air 6 1 is opposite to the outgoing direction, from the injection port 52 Injected as described above, according to this incineration gas 6 1 is sprayed to the incinerated 6 0 and produces gas 6 1 becomes combustion gas 6 2 and reverses the combustion air 6 1 residence time in the primary combustion chamber incinerator In other words, the contact time of the compound 60 is more effective than that of using the incinerator (A1), and the incinerator (A1) is used to inhale the burned gas 62 to the aforementioned outlet pipe. 5 1 injection port 5 2 is injected more to accept the burner 1 10 fire port ij result 'not only can reduce the harmful gas composition of dioxin and the like caused by the aforementioned combustion, because the mouth of the air diffuser 51 is opened 9 a, so once Combustion gas 62, so that although the amount of the harmful gas components such as dioxin and the like mentioned above tend to keep moving forward, they stop at the plug and nowhere to go, and then turn to the original opening 9a. 9a is provided inside Diffusion pipe 51, so the flow of combustion gas 62 in the opening 9a for the gasification furnace (A1) 'After the primary combustion air is burned', this primary combustion air flows to the outlet opening 9a, so that one to one The ice retention time is longer than that of downstream combustion. The primary combustion air 6 1 is longer than the incinerated combustion incinerator. Therefore, the downstream combustion incinerator can make the incinerator flow to the outlet 9 a for incineration. Immediately within the opening 9a, fresh primary combustion air 6 1 or the flame (F 1) emitted will be accepted for combustion. Even the amount of fumes contained in the gas 62 is reduced. Especially in this first implementation, an outlet air is provided in the vicinity of the injection port 5 2 and the amount of the fumes contained in the air 62 which is effectively blown to and supplied to the combustion body 62 is indeed reduced.

1228581 V. Description of the invention (16) In addition, the inside of the outlet opening 9a is at a high temperature of about 80 ° C or above due to the heat of the combustion gas 62, so the diffuser 51 is set in such a south The warm and sad exit is inside the opening 9a. However, since the primary combustion air 61 is circulated inside the diffuser tube 51, the diffuser tube 51 and the combustion-supporting burner 10 and the combustion-supplying fuel supply tube 27 which are provided in the diffuser tube 51 The primary combustion air circulating in 51 is cooled by 61, so the diffuser tube 51, the burner 10, and the fuel supply tube 27 are not thermally damaged. Then, the combustion gas 62 is opened through the outlet. 9 a flows into the secondary combustion chamber 2 through the combustion gas flow path 9. In the secondary combustion chamber 2, a combustion gas 62 is burned by a flame from a secondary burner (not shown) (secondary combustion). In this way, the fumes remaining in the aforementioned combustion gas 62 can be removed and smokeless, and at the same time, harmful gas components such as dioxin remaining in the aforementioned combustion gas 62 can be removed almost completely. Then, the exhaust gas 65 is sucked into the exhaust gas outlet opening 7a and flows to the exhaust gas purification device. When all the incinerators 60 have been burned, the blower 55 is stopped and the injection of the primary combustion air 61 is stopped. After the furnace (A1) is cooled, the ash removal door (not shown) provided on the side wall 6 of the primary combustion chamber 1 is opened, and the ash remaining in the primary combustion chamber 1 is removed. In the incinerator (A1) as described above, the injection direction of the flame (F1) injected from the fire port 11 of the burner 10 is set to the injection direction of the primary combustion air 61 injected from the injection port 52 of the diffuser pipe 51 as Similarly, the flame (F 1) travels along the flow direction of the primary combustion air 61. the other side,

1228581 V.
