[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] like Figure 1 The coffee roasting exhaust purifier shown in the figure has an air intake pipe 1 connected to the upper side wall of the cyclone dust collector 2. The interior of the cyclone dust collector 2 is a cylindrical cavity structure and its lower part is conical. The air guide pipe 5 is arranged in the middle of the cyclone dust collector 2. The air intake pipe 1 introduces the exhaust gas into the interior of the cyclone dust collector 2. After the exhaust gas hits the inner wall of the cyclone dust collector 2, under the action of the air guide pipe 5, the exhaust gas forms a cyclone around the air guide pipe 5 and is discharged from the cyclone dust collector 2 from the bottom inlet of the air guide pipe 5.

[0018] A circulating spray system 3 for dust and odor removal of the tail gas is arranged on the cyclone dust collector 2, the circulating spray system 3 comprises a plurality of water mist spray heads 31 arranged on the top wall inside the cyclone dust collector 2, the water mist spray heads 31 are communicated with a water storage tank 32 arranged directly below the cyclone dust collector 2, water is pumped to the water mist spray heads 31 through a pump body arranged on the pipeline, the water mist spray heads 31 spray water mist to remove dust and odor from the tail gas entering the cyclone dust collector 2, the dripping water flows along the inner wall of the cyclone dust collector 2 to the water seal device 4 at the bottom of the cyclone dust collector 2, the water seal device 4 comprises an annular sealing plate fixed to the bottom of the cyclone dust collector 2, and a water absorbing cotton ring is arranged on the annular sealing plate, the water absorbing cotton ring can be made of PP cotton and can be detached from the annular sealing plate for cleaning or replacement, the water absorbing cotton ring absorbs water to form a water seal capable of blocking the tail gas, and the excess water seeps into the water storage tank 32, thereby forming a closed water circulation loop, in order to further treat the water accumulated in the water storage tank 32, a filter tank 6 for filtering water is connected to the pipeline connected with the water mist spray head 31, and the filter tank 6 is filled with activated carbon and a filter screen, so that the water can be further filtered and cleaned.

[0019] The coffee roasting tail gas purifier disclosed by the utility model, in use, the air inlet pipe 1 guides the tail gas into the cyclone dust collector 2, the tail gas forms a cyclone around the air guide pipe 5, part of the large tail gas particles precipitate and fall when colliding with the inner wall of the cyclone dust collector 2 along the cyclone, at the same time, the water mist spray head 31 sprays water mist to make the finer particles precipitate and remove the odor of the tail gas, the treated tail gas is blocked by the water seal, and then is discharged from the air guide pipe 5 to the cyclone dust collector 2, after that, the water in the water storage tank 32 precipitates and is filtered by the filter tank 6, and the treated water is pumped into the cyclone dust collector 2 by the pump body again, so that the water circulation tail gas treatment is realized.
