Description

Technical Field

[0001] The utility model relates to the field of pyrolysis gasification furnaces, and relates to a main structure of a pyrolysis gasification furnace. Background Art

[0002] Pyrolysis gasification furnace is used for pyrolysis and incineration of domestic waste. It is widely used in waste treatment and has good use effect. With the continuous development of society, people's domestic waste generation is gradually increasing, so the demand for the use of pyrolysis gasification furnace is also gradually increasing;

[0003] After checking the public (announcement) number: CN214619562U, a pyrolysis gasification furnace is disclosed. This technology discloses that "it includes a furnace body, and the left end of the furnace body is provided with a feed port, a gas delivery pipe and an oxygen delivery pipe from top to bottom in sequence. A furnace door is installed on the lower side of the right end of the furnace body, and a smoke exhaust port is provided on the upper end of the furnace body. Support legs are fixed to the lower parts of the front, back, left and right ends of the furnace body. The ash collecting box is convenient for collecting the ash discharged from the ash outlet, and the ash collecting box can be rotated by controlling the motor by the forward and reverse switch. In this way, when one of the ash collecting boxes is full, it is convenient to remove the ash collecting box. At the same time, the other ash collecting box can also collect the ash discharged from the ash outlet, so as not to affect the collection work. The ash collecting box is easy to disassemble and assemble, which is conducive to the staff to clean the ash in the ash collecting box, so it is easy to use, so as to solve the problem that in the existing pyrolysis gasification furnace, when the ash outlet of the furnace body discharges ash, it is not convenient for the staff to collect and clean the generated ash, resulting in an increase in the workload of the staff";

[0004] In the above-mentioned comparative documents, since the smoke exhaust port is designed as an open structure, a large amount of harmful exhaust gas will be directly discharged through the smoke exhaust port when burning inside the furnace body, and there is no purification device on the smoke exhaust hole to filter and purify the exhaust gas. Therefore, during the discharge process, the exhaust gas will pollute the air;

[0005] In order to solve the above problems, a pyrolysis gasification furnace main structure is proposed in the present application. Summary of the invention

[0006] The utility model aims at the technical problems existing in the prior art and provides a main structure of a pyrolysis gasification furnace.

[0008] The pressure relief assembly includes a pressure relief pipe, which is arranged on a cover plate. The bottom of the pressure relief pipe passes through the explosion-proof plate. An air inlet groove is provided on the outer side of the pressure relief pipe located at the bottom of the explosion-proof plate. A sliding groove is provided on the inner wall of the pressure relief pipe. A sliding frame is slidably connected to the sliding groove. A connecting rod is provided on the top of the sliding frame.

Through the threaded guide groove arranged inside the combustion box, the internal hot air flow of the combustion box forms a vortex shape under the action of the threaded guide groove during combustion, so that the combustion box is heated evenly, and the exhaust gas generated during combustion is discharged upward through the first air outlet pipe in a vortex shape.

[0010] The bottom of the exhaust gas treatment box is fixedly connected to a second air inlet pipe, the top of the exhaust gas treatment box is fixedly connected to a second air outlet pipe, the inner surface wall of the exhaust gas treatment box is provided with a guide block, and a combustion nozzle is embedded and installed on the guide block. There are four guide blocks in total, and the four guide blocks are distributed in a ring shape. The incoming exhaust gas is subjected to secondary treatment through 4 pairs, and the exhaust gas is guided by the guide blocks so that the exhaust gas rotates counterclockwise and is discharged through the second air outlet pipe. During the flow of the exhaust gas, the exhaust gas is subjected to secondary combustion under the action of the combustion nozzle, so that the impurities in the exhaust gas are further burned and crushed, thereby reducing harmful substances in the exhaust gas.

[0011] The feed box is fixedly connected with a third air intake pipe, and a snap-on lock is provided on the top of the feed box. There are three snap-on locks in total, and the three snap-on locks are distributed in a ring shape.

The exhaust gas entering the feed box can preheat the material, thereby improving the combustion efficiency. The three snap-on locks are provided to limit the feed box and the cover plate to prevent the cover plate from being pushed upward due to the high internal temperature during use, and a quick-release structure is provided between the snap-on lock and the snap-on hook to facilitate the opening or closing of the cover plate at a later time.

[0012] A first connecting pipe is provided between the first air outlet pipe and the second air inlet pipe, the first air outlet pipe and the second air inlet pipe are connected to each other through the first connecting pipe, a second connecting pipe is provided between the second air outlet pipe and the third air inlet pipe, the second air outlet pipe and the third air inlet pipe are connected through the second connecting pipe, the first air outlet pipe and the second air inlet pipe are connected through the first connecting pipe, the exhaust gas in the combustion box is introduced into the exhaust gas treatment box through the first connecting pipe, the second air outlet pipe and the third air inlet pipe are connected through the second connecting pipe, and the treated exhaust gas in the combustion nozzle is introduced into the feed box through the second connecting pipe.

[0015] The strength of the cover plate is increased by the explosion-proof plate to prevent the pyrolysis gasification furnace body from being deformed and damaged due to excessive internal pressure after the temperature rises. Furthermore, when the internal pressure of the pyrolysis gasification furnace body continues to rise, the internal pressure of the feed box is relieved under the action of the pressure relief assembly. When the steam enters the pressure relief pipe after passing through the air inlet groove, when the steam reaches a certain pressure, it drives the pressure relief cover to be pushed up. At this time, a gap is generated between the pressure relief cover and the pressure relief pipe, so that the internal steam can be discharged through the gap, thereby reducing the internal pressure. There are five pressure relief components in the formula. When the pressure is small, the distance between the pressure relief pipe and the pressure relief cover is relatively small. When the pressure is large, the five pressure relief covers are completely pushed up to achieve the effect of rapid pressure relief.

[0016] Through the setting of the threaded guide groove, the exhaust gas burned in the combustion box rotates upward in a threaded shape, and is further treated for a second time by the exhaust treatment box. The exhaust gas is guided to the second exhaust pipe through the guide block. During the flow of the exhaust gas, the exhaust gas is secondary burned under the action of the combustion nozzle, which further reduces the volume of impurities and reduces harmful substances through combustion. The treated exhaust gas enters the feed box to preheat the material, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
