A slag storage tank 2 is fixedly connected to the upper side of the support leg 1. A gasifier 3 is fixedly connected to the upper side of the slag storage tank 2. A conveying pipe 513 and an output pipe 411 are fixedly connected to the two output ends of the gasifier 3, respectively. A detachable gas delivery pipe is provided at the end of the output pipe 411 away from the gasifier 3. An oxygen distributor 514 is provided on the conveying pipe 513. A guide pipe 512 is movably installed at the output end of the conveying pipe 513. The guide pipe 512 extends into the interior of the gas delivery pipe. A diversion structure is provided at the center of the gas delivery pipe to guide the gas ejected from the guide pipe 512. The bottom of the gas pipeline is equipped with a flip-up plate 712 that can be rotated. During use, the discharge rate of the output pipe 411 determines the discharge rate of the guide pipe 512, which is controlled by the oxygen distributor 514. When the discharge rate of the guide pipe 512 is small, it is moved so that its output end is close to the input end of the distribution structure. At this time, the gas discharged through the guide pipe 512 can be dispersed by the distribution structure and discharged to mix with the gas discharged from the output pipe 411. When a large discharge is required, the guide pipe 512 is moved... The guide pipe 512 is moved to the bottom of the gas pipeline, and then the flip plate 712 is flipped. At this time, the gas ejected through the guide pipe 512 is guided by the flip plate 712 and collides with the gas ejected from the output pipe 411, allowing the two gases to mix together and improving combustion efficiency. A second mounting cavity 711 is opened on the bottom of the guide pipe 413. The flip plate 712 is movably installed inside the second mounting cavity 711. A rotating shaft 713 is fixedly connected to the outside of the guide pipe 413 corresponding to the position of the flip plate 712. The output end of the rotating shaft 713 is fixedly connected to the side of the flip plate 712.

The injection pipe 414 is a trumpet-shaped pipe, and its diameter gradually decreases from the end near the guide pipe 413 to the end away from the guide pipe 413. Gas ejected from inside the gasifier 3 is sequentially ejected through the output pipe 411, connecting pipe 412, guide pipe 413, and injection pipe 414. A guide pipe 413 is fixedly connected to one end of the output pipe 411 corresponding to the connecting pipe 412. A second connecting plate 422 is fixedly connected to one end of the connecting pipe 412 corresponding to the output pipe 411.

When the diversion pipe 512 moves to the position of the opening of the guide barrel 612, the gas enters the interior of the guide barrel 612 through the diversion pipe 512 and then flows out evenly from the guide cavity 613, improving the mixing effect between gases.

[0026] The working principle of this utility model:

[0027] In use, the discharge rate of the outlet pipe 411 determines the discharge rate of the drainage pipe 512, which is controlled by the oxygen distributor 514. When the discharge rate of the drainage pipe 512 is small, the drainage pipe 512 is moved so that its output end is close to the input end of the splitter structure. At this time, the gas discharged through the drainage pipe 512 can be dispersed by the splitter structure and discharged to mix with the gas discharged from the outlet pipe 411. When the drainage pipe 512 needs to discharge a large amount of gas, the drainage pipe 512 is moved so that its output end is close to the input end of the splitter structure. 12 moves to the bottom inside of the gas pipeline and then flips the flip plate 712. At this time, the gas ejected through the guide pipe 512 is guided by the flip plate 712 and collides with the gas ejected inside the output pipe 411, so that the two gases can be mixed together. The gas ejected from the gasifier 3 passes through the output pipe 411, the connecting pipe 412, the guide pipe 413 and the injection pipe 414 in sequence. The guide pipe 512 moves to the opening of the guide barrel 612. The gas enters the interior of the guide barrel 612 through the guide pipe 512 and then flows out evenly from the guide cavity 613.
