The sealing tube 1 and the liquid storage tank 7 are installed on the bottom plate 11 to form a U-shaped tube through a liquid delivery pipe 1 5.

[0029] Furthermore, a through opening is provided at the top of the bottom plate 11 and a purification chamber 13 is fixedly connected at the through opening. The bottom of the purification chamber 13 is hollow, and a filter plate 14 and a support rod 17 are fixedly connected to the inner wall of the purification chamber 13. A fixing ring 16 is fixedly connected to one end of the support rod 17 away from the inner wall of the purification chamber 13. A connecting shaft 15 is rotatably connected to the middle of the fixing ring 16. A circular plate 18 is fixedly connected to the bottom of the connecting shaft 15. A cleaning rod 19 is fixedly connected to the side of the circular plate 18. The bottom of the cleaning rod 19 is rotatably connected to the top of the filter plate 14. A fan blade 20 is fixedly connected to the top of the connecting shaft 15. The filter plate 14 filters and purifies the coal gas. When the coal gas passes through the purification chamber 13, the fan blade 20 is driven to rotate, thereby driving the cleaning rod 19 to clean the surface of the filter plate 14 to avoid blockage.

[0030] Furthermore, a connecting pipe four 22 is fixedly connected to the top of the purification bin 13, one end of the connecting pipe four 22 away from the purification bin 13 is fixedly connected to the outer opening of the connecting pipe one 3, and a connecting pipe three 21 is fixedly connected to the lower side of the purification bin 13.

The air inlet pipe 9 is higher than the highest point of the sealed tube 1. The liquid storage bin 7 and the sealed tube 1 are connected through the liquid delivery pipe 1 5 and form a U-shaped tube principle. As the coolant in the liquid storage bin 7 increases, the coolant flows into the sealed tube 1 through the liquid delivery pipe 1 5, and is finally discharged through the liquid discharge pipe 6. The high-temperature coal gas enters the purification bin 13 through the connecting pipe 3 21. At this time, the bottom of the purification bin 13 is blocked by the collecting bin 25 and the side plate 26, and the coal gas cannot leak out, so that the coal gas flows upward through the filter plate 14 and the connecting pipe 4 22 into the connecting pipe 1 3 and the heat exchange tube 2. The coal gas is filtered by the filter plate 14 to filter out the solid impurities in the coal gas, and the coal gas drives the fan blades 20 to rotate when it flows upward, thereby driving the connecting shaft 15 and the cleaning brush rod 19 to rotate, cleaning The bristles of the brush rod 19 clean the surface of the filter plate 14, and the attached solid particles are brushed off through the filter holes of the filter plate 14 and dropped into the collecting bin 25 for collection to avoid clogging of the filter plate 14. After the high-temperature coal gas enters the heat exchange tube 2, it gradually moves down along the inside of the heat exchange tube 2 to the connecting pipe 24 and is discharged to the coal gas recovery equipment. The coal gas moves from top to bottom in the heat exchange tube 2, and the coolant in the sealed tube 1 flows from bottom to top. The heat exchange tube 2 is spiral, which lengthens the heat exchange time between the high-temperature coal gas and the coolant, thereby improving the cooling effect of the coal gas. This solves the problem that the heat exchange tube is in a straight line shape, which makes the coal gas pass through the inside faster, the contact time with the cooling medium is shorter, and the heat exchange cooling is not sufficient. After the coolant absorbs heat and recovers it, the waste heat can be reused, which is more environmentally friendly. During maintenance, use a screwdriver to disengage the screw rod 27 from the screw hole 24, take the collecting bin 25 out of the fixing plate 23, clean the collecting bin 25, and clean out the solid impurity particles.
