[0025] Furthermore, a transmission pipe 102 is fixed to the top of the spray tank 1 by welding, and a drying box 4 is fixedly connected to the outside of the transmission pipe 102. A cavity is provided inside the drying box 4, and a sliding rod 401 is slidably connected to the inside of the cavity of the drying box 4. A fixed frame 402 is fixedly connected to the outside of the sliding rod 401, and a square groove is provided inside the fixed frame 402. A filter element 406 is fixedly connected to the inside of the square groove of the fixed frame 402, and the filter element is fixed by pressing the sliding rod 401 against it.

[0029] Working principle:

[0030] First, the staff will let the waste gas after the production of calcium dihydrogen phosphate enter the interior of the spray tank 1 through the air inlet pipe 205. At this time, the fixed rod 201 at the top of the base 2 drives the rotating arm 202 to rotate. At this time, the spray head 203 dilutes the waste gas entering the interior of the spray tank 1, thereby reducing the concentration, and cooperates with the atomizer 204 to atomize the harmful gas and discharge it from the inside of the transmission pipe 102. At this time, the harmful objects after being sprayed are discharged from the inside of the air outlet pipe 206 and enter the inside of the drain 3. At this time, the sewage flows to the bottom end of the bottom plate 307. At this time, the lifting rod 306 drives the bottom plate 307 to rise, and when there are more impurities on the top of the bottom plate 307, the impurities are pushed away by pushing the guard plate 304, and then the impurities are collected. The cleaned sewage flows from the second filter plate 302 to the inside of the first filter plate 301, and then the water is slowly clarified to achieve the collection of sewage.

[0031] When the exhaust gas enters the drying box 4 from the inside of the transmission pipe 102, by pushing the clamping rod 403, the clamping rod 403 pushes the fixed frame 402 to slide into the inside of the sealing box 404, and the sliding rod 401 slides inside the drying box 4. The filter element 406 can be disassembled and replaced, which can effectively prevent exhaust gas leakage.
