The water inlet pipe 51 passes through the top of the purification box 2 and the bottom is located inside the spray chamber 3. The bottom of the water inlet pipe 51 is connected to a nozzle 52. The existing water source can draw water into the water inlet pipe 51 until it is sprayed out from the nozzle 52 through the water inlet pipe 51. When the water sprayed from the nozzle 52 comes into contact with the exhaust gas, the dust, oil and small fibers in the exhaust gas will be mixed with the water and fall to the bottom.

[0024] An exhaust mechanism 6 is arranged on the partition 21, and the exhaust mechanism 6 includes an exhaust pump 61 fixed to the partition 21, and the exhaust pump 61 is respectively connected with an air inlet pipe 62 and an air outlet pipe 63, the air inlet pipe 62 passes through one side of the partition 21 and is connected with the inside of the spray chamber 3, and the air outlet pipe 63 is located inside the purification chamber 4; by starting the exhaust pump 61, the preliminary filtered exhaust gas inside the spray chamber 3 can be sucked into the inside of the air inlet pipe 62, and discharged from the air outlet pipe 63 to the inside of the purification chamber 4.

When the two limiting blocks 78 are rotated to between the limiting plate 1 74 and the limiting plate 2 75, the limiting plate 1 74 and the limiting plate 2 75 can both play a limiting role, so that the filter screen 1 412 and the limiting frame 71 can be fixed to the support plate 1 41.

[0027] Support blocks 423 are fixedly arranged on the inner walls of both sides of the through groove 421, and the filter screen 422 is installed on the two support blocks 423.

When the fixing block 86 is in conflict with the top of the fixing plate 83, the fixing block 86 is in a horizontal state. Since the length of the fixing block 86 is greater than the width of the fixing groove 84, the fixing block 86 can fix the fixing plate 83 and the filter screen 422. When it is necessary to remove the filter screen 422, the fixing block 86 only needs to be screwed to the horizontal state to flip up the fixing plate 83.

[0028] By setting the spray mechanism 5, the exhaust gas can be preliminarily filtered, and the dust, oil and small fibers in the exhaust gas can be mixed with the sprayed water. By setting the exhaust mechanism 6, the preliminarily filtered exhaust gas can be discharged into the purification chamber 4. The setting of the filter mesh 1 412 and the filter mesh 2 422 can filter the exhaust gas inside the purification chamber 4 for multiple times, which can not only avoid the phenomenon that the filter mesh 1 412 and the filter mesh 2 422 are blocked by dust, but also make the gas discharged from the exhaust pipe 43 meet the emission standards.
