Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-4 The present invention provides the following technical solution: an exhaust gas purification device for environmental protection engineering, including a purification component 1, an air inlet pipe 6 provided on one side of the purification component 1, a three-way catalytic converter 3 fixedly installed above the purification component 1, a plurality of support components 4 fixedly installed below the purification component 1, a drying exhaust device 2 provided above the three-way catalytic converter 3, and the purification component 1 and the air inlet pipe 6 are connected by a filter lifting device 5.

[0023] Specifically, the drying and venting device 2 includes a connecting box 21, a blocking block 22, an electric telescopic rod 23, silica gel desiccant 24, a mesh 25, a movable cylinder 26, a ventilation mesh 27, and an venting assembly 28. The connecting box 21 is fixedly installed above the three-way catalytic converter 3. The movable cylinder 26 is provided inside the connecting box 21. The connecting box 21 and the movable cylinder 26 are connected by the electric telescopic rod 23. The mesh 25 is fixedly installed inside the movable cylinder 26. Silica gel desiccant 24 is filled inside the movable cylinder 26 and above the mesh 25. The blocking block 22 is threadedly installed on the top of the connecting box 21 and above the silica gel desiccant 24. The ventilation mesh 27 is fixedly installed on the top of the connecting box 21 and to one side of the blocking block 22. The venting assembly 28 is fixedly installed above the ventilation mesh 27.

[0024] By adopting the above technical solution, staff can dehumidify the purified exhaust gas when needed by using the combination of silica gel desiccant 24 and movable cylinder 26, thereby better meeting the work needs in different situations.

[0025] Specifically, the air outlet assembly 28 includes a suction cup 281 and a hose 282. The hose 282 is fixedly installed above the ventilation net 27, and the suction cup 281 is fixedly installed above the end of the hose 282 away from the ventilation net 27.

[0026] By adopting the above technical solution, the staff can adjust the air outlet position by using the suction cup 281 and the hose 282 when needed, so as to better meet the work needs in different situations.

[0027] In this embodiment, when the device is needed to purify exhaust gas in an environmental protection project, if dehumidification of the purified exhaust gas is required, the operator must first unscrew the block 22 in the drying exhaust device 2, put enough silica gel desiccant 24 into the moving cylinder 26, and then reinstall the block 22 through the thread. The electric telescopic rod 23 is then activated, which moves the moving cylinder 26 and other structures to the space between the three-way catalytic converter 3 and the ventilation net 27. The suction cup 281 in the exhaust assembly 28 then adsorbs and fixes the end of the hose 282 in the required position. The exhaust gas is then sent into the purification assembly 1 through the air inlet pipe 6. The exhaust gas is purified by the purification assembly 1 and the three-way catalytic converter 3. The purified exhaust gas enters the connecting box 21, then passes through the partition 25 and comes into contact with the silica gel desiccant 24. The silica gel desiccant 24 removes the moisture from the purified exhaust gas. The purified exhaust gas then passes through the ventilation net 27 and the hose 282 and is discharged, thus completing the purification work. The support assembly 4 plays a supporting role.

[0028] Example 2

[0029] The difference between this embodiment and embodiment 1 is that the filter lifting device 5 includes a connecting cylinder 51, a filter screen 52, a lifting assembly 55, and a threaded block 56. The connecting cylinder 51 is fixedly installed on the side of the purification assembly 1 near the air inlet pipe 6. The filter screen 52 is fixedly installed on the inner side of the connecting cylinder 51. The threaded block 56 is installed at the bottom of the connecting cylinder 51 by threads. The connecting cylinder 51 and the air inlet pipe 6 are connected by the lifting assembly 55.

[0030] By adopting the above technical solution, staff can filter larger impurities in the exhaust gas when needed through the cooperation of structures such as the connecting cylinder 51 and the filter screen 52, thereby reducing the possibility of the device being blocked due to larger impurities.

[0031] Specifically, the filter lifting device 5 also includes a brush body 53 and a motor 54. The motor 54 is fixedly installed on the side of the connecting cylinder 51 near the air inlet pipe 6, and the brush body 53 is fixedly installed on the side of the motor 54 near the filter screen 52.

[0032] By adopting the above technical solution, the staff can clean the surface of the filter screen 52 when needed by the cooperation of the brush body 53 and the motor 54, thereby preventing the filter screen 52 from becoming clogged during operation.

[0033] Specifically, the lifting assembly 55 includes a fixed tube 551, a lifting tube 552, and a tightening screw 553. The fixed tube 551 is fixedly installed on the side of the connecting tube 51 near the air intake pipe 6 and outside the motor 54. The lifting tube 552 is fixedly installed on the side of the air intake pipe 6 and inside the fixed tube 551. The tightening screw 553 is threaded onto the top of the fixed tube 551.

[0034] By adopting the above technical solution, the staff can adjust the height of the air intake pipe 6 by cooperating with structures such as the fixed pipe 551 and the lifting pipe 552 when needed, so as to better meet the work needs in different situations.

[0035] In this embodiment, when needed, the operator can rotate the tightening screw 553 inside the lifting component 55 of the filter lifting device 5 to release the lifting pipe 552, and then pull the lifting pipe 552 and the air inlet pipe 6 to the required height. Then, rotate the tightening screw 553 in the opposite direction to tighten the lifting pipe 552, thereby adjusting the height of the air inlet pipe 6. When the exhaust gas passes through the air inlet pipe 6, it will pass through the lifting pipe 552 and the fixed pipe 551 and enter the connecting cylinder 51. The filter screen 52 intercepts larger impurities in the exhaust gas, thereby reducing the possibility of the device being blocked due to larger impurities. The motor 54 is started to drive the brush body 53 to rotate, thereby cleaning the surface of the filter screen 52, preventing the filter screen 52 from being blocked, and ensuring the normal operation of the work. The operator can unscrew the threaded block 56 to remove the impurities inside the connecting cylinder 51.

[0036] The structure and principle of the purification component 1 (comprising a purification chamber, a fixed plate, a horizontal pipe, a liquid adding pipe, an atomizing nozzle, an air inlet pipe, an annular pipe, a liquid outlet pipe, a transmission pipe, a connecting pipe, a water pump, a fixed rod, a through hole, a filter group, and an air outlet), the three-way catalytic converter 3, and the support component 4 (comprising a support plate and support legs) in this utility model have been disclosed in a waste gas purification device for environmental engineering disclosed in Chinese patent application number 201921690076.6. Its working principle is that during use, external waste gas enters the inner cavity of the annular pipe along the air inlet pipe and is discharged through the air outlet to react with the reaction solution in the inner cavity of the purification chamber. Harmful gases in the exhaust gas are absorbed by the solution. Due to buoyancy, the gas rises and leaves the inner cavity of the reaction solution. The reaction solution is then pumped through the transmission pipe and connecting pipe into the inner cavity of the horizontal pipe and sprayed out through the atomizing nozzle to perform a secondary absorption reaction on the exhaust gas leaving the reaction solution. The exhaust gas continues to rise, passes through the through holes, and undergoes adsorption and sterilization by the activated carbon adsorption layer and the silver oxide sterilization layer to complete the third absorption treatment. Finally, it is discharged after a fourth reaction treatment by the three-way catalytic converter. Through the combination of the above structures, the equipment can achieve a good purification effect. The multi-stage purification treatment is cleaner and suitable for widespread use.

[0037] The working principle and usage process of this utility model are as follows: When an environmental protection project requires the use of a device to purify waste gas, if it is necessary to dehumidify the purified waste gas, the operator must first unscrew the block 22 in the drying outlet device 2, put enough silica gel desiccant 24 into the moving cylinder 26, and then reinstall the block 22 through the thread. The electric telescopic rod 23 is then activated, which moves the moving cylinder 26 and other structures to between the three-way catalytic converter 3 and the ventilation net 27. The suction cup 281 in the outlet assembly 28 then adsorbs and fixes the end of the hose 282 to the required position. The waste gas is then sent into the purification assembly 1 through the inlet pipe 6. The purification assembly 1 and the three-way catalytic converter 3 purify the waste gas. The purified waste gas enters the connecting box 21, then passes through the partition net 25 and comes into contact with the silica gel desiccant 24. The silica gel desiccant 24 removes the moisture from the purified waste gas. The exhaust gas passes through the ventilation net 27 and the hose 282 and is discharged, thus performing purification work. The support component 4 plays a supporting role. When needed, the operator can turn the tightening screw 553 in the lifting component 55 of the filter lifting device 5 to release the lifting pipe 552, and then pull the lifting pipe 552 and the air inlet pipe 6 to move to the required height. Then, turn the tightening screw 553 in the opposite direction to tighten the lifting pipe 552, thereby adjusting the height of the air inlet pipe 6. After the exhaust gas passes through the air inlet pipe 6, it will pass through the lifting pipe 552 and the fixed pipe 551 and enter the connecting cylinder 51. The filter screen 52 intercepts larger impurities in the exhaust gas, thereby reducing the possibility of the device being blocked due to larger impurities. The motor 54 is started to drive the brush body 53 to rotate, thereby cleaning the surface of the filter screen 52, preventing the filter screen 52 from being blocked, and ensuring the normal operation of the work. The operator can unscrew the threaded block 56 to remove the impurities in the connecting cylinder 51.
