[0028] It should be noted that by starting the fan 26, the air flow will be driven to flow from left to right, and then the exhaust gas generated by the environmental protection project construction will flow to the right. The exhaust gas will first contact the coarse filter 21, and the coarse filter 21 will block the large particles of impurities in the exhaust gas, so that the large particles of impurities will not enter the box 1. The set fine filter 25 will block the small particles of impurities in the exhaust gas to achieve a better filtering effect. Then the exhaust gas is purified by two purification plates 41 to meet the exhaust standard. The set impurity removal net 27 will filter the exhaust gas for the last time, and finally the exhaust gas will be discharged to the outside through the exhaust pipe 3. The blocked small particles of impurities will be located in The middle position of the coarse filter 21 and the fine filter 25 is formed by pulling the two baffles 28 outward, so that the upper baffle 28 moves upward and the lower baffle 28 moves downward, thereby driving the slider 201 to slide along the slide groove 23, thereby compressing the spring 29, and then the coarse filter 21 can be taken out, and small particles of impurities will slide out along the inclined block 24, achieving a certain cleaning effect, and the cleaned coarse filter 21 is replaced in the box body 1, and then the baffle 28 is loosened. Under the action of the slider 201, the two baffles 28 move to the middle position, thereby completing the fixation of the coarse filter 21 and achieving a better cleaning effect.

[0029] like Figure 2 As shown, two inclined blocks 24 are fixedly connected to the upper and lower parts of the opposing surfaces of the fine filter 25 and the coarse filter 21, and the opposing surfaces of the two inclined blocks 24 are inclined in opposite directions.

[0034] It should be noted that by lifting the handle 43 upwards, the connecting frame 46 is driven to move upwards, so that the connecting frame 46 is separated from the box body 1, the purification plate 41 can be taken out, and after replacing or cleaning the purification plate 41, the connecting frame 46 is realigned with the square groove 45 and pushed downwards, so that the connecting frame 46 enters the box body 1, and at the same time, the limit groove 47 set on the connecting frame 46 will move along the limit rod 42 until the limit groove 47 completely covers the limit rod 42. The limit rod 42 set can prevent the connection frame 46 from moving, and the fixing effect is better, so as to achieve the effect of quick replacement. At the same time, the sealing gasket 44 set will enter the square groove 45, and the sealing gasket 44 set will be slightly compressed to make it fit the surface of the square groove 45 more closely, so as to achieve better sealing and prevent the overflow of exhaust gas, so as to achieve the effect of better purifying the exhaust gas.

[0036] It should be noted that the provided sealing gasket 44 will enter into the square groove 45 and will be slightly compressed at the same time, so that it can fit more closely to the surface of the square groove 45, thereby achieving better sealing and preventing the exhaust gas from overflowing.

The fine filter 25 set will block the small particles of impurities in the exhaust gas, achieving a better filtering effect. Then the exhaust gas is purified by the two purification plates 41 to meet the exhaust standard. The impurity removal net 27 set will filter the exhaust gas for the last time, and finally the exhaust gas will be discharged to the outside through the exhaust pipe 3. The small particles of impurities blocked will be located in the middle position of the coarse filter 21 and the fine filter 25. By pulling the two baffles 28 outward, the upper baffle 28 moves upward, and the lower baffle 28 moves downward, thereby driving the slider 201 to slide along the slide groove 23, thereby compressing the spring 29, and then the coarse filter 21 can be taken out, and the small particles of impurities will slide out along the inclined block 24, achieving a certain cleaning effect, and cleaning The coarse filter 21 is then placed back in the box 1, and the baffle 28 is then released. Under the action of the slider 201, the two baffles 28 move to the middle position, thereby completing the fixation of the coarse filter 21 and achieving a better cleaning effect. By lifting the grip 43 upward, the connecting frame 46 is driven to move upward, so that the connecting frame 46 is separated from the box 1, and the purification plate 41 can be taken out. After replacing or cleaning the purification plate 41, the connecting frame 46 is aligned with the square groove 45 again and pushed downward, so that the connecting frame 46 is moved forward. The limiting rod 42 can prevent the connection frame 46 from moving, and the fixing effect is better, so as to achieve the effect of quick replacement. At the same time, the sealing gasket 44 will enter the square groove 45, and the sealing gasket 44 will be slightly compressed to make it fit the surface of the square groove 45 better, so as to achieve better sealing and prevent the exhaust gas from overflowing, thereby achieving the effect of better purifying the exhaust gas.
