Description

Technical Field

[0001] This application relates to the field of waste gas purification technology, and in particular to an environmental protection device for waste gas purification. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life. Industrial production processes generate large amounts of toxic and harmful odorous gases, which, if directly emitted, will seriously pollute the environment and affect human health.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist:

[0004] First, some waste gases with more impurities have smaller particle sizes, which reduces the resistance when passing through the filter screen. This can cause the filter screen to be unable to completely filter the waste gas, thus reducing its filtration efficiency.

[0005] Secondly, after prolonged use, dust particles tend to adhere to the surface of the filter screen in some purification equipment, causing the filter screen to become clogged and reducing the purification effect of the equipment. Furthermore, the process of replacing the filter screen is relatively cumbersome, which reduces the purification efficiency of the equipment during operation.

[0006] To address the aforementioned problems, the inventors have proposed an environmentally friendly waste gas purification device to solve these issues. Utility Model Content

[0007] In order to improve the problems of insufficient filtration of small waste particles in the exhaust gas of some existing devices and the cumbersome filter replacement, the purpose of this utility model is to provide an environmental protection device for exhaust gas purification.

[0008] To solve the above problems, this utility model provides the following solution: an environmental protection device for purifying waste gas, including a housing, with an air inlet and an air outlet at both ends of the housing, a humidification mechanism inside the housing near the air inlet, and a purification mechanism inside the housing near the air outlet. The humidification mechanism includes a water tank, which is fixedly installed on the top surface of the housing. Water supply pipes are connected to both sides of the water tank. A support rod is fixedly installed on the upper inner wall of the housing, and two atomizing nozzles are fixedly installed at the bottom end of the support rod. The bottom ends of the two water supply pipes are respectively connected to the two atomizing nozzles. A water collection trough is formed on the lower inner wall of the housing, and a water outlet is formed on the bottom surface of the water collection trough.

[0009] Preferably, the purification mechanism includes a sealing plate, which is movably inserted into one side of the housing. Multiple filter screens are fixedly installed on one side of the sealing plate, with the sides of each filter screen fitting against the inner wall of the housing. A fixing plate is fixedly installed on the side of the sealing plate facing away from the filter screens. Multiple clamping plates are fixedly installed on both sides of the fixing plate. Multiple fixing rods are fixedly installed on one side of the housing. Mirror-distributed springs are fixedly installed inside each of the fixing rods. Rotating blocks are fixedly installed at opposite ends of two springs. Both rotating blocks are rotatably installed inside the fixing rods. The clamping plates are engaged with the outer surface of the fixing rods.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting up a humidification mechanism, can increase the humidity in the exhaust gas through the atomizing nozzle in the humidification mechanism, thereby causing the waste to agglomerate. After agglomeration, the particle size of the particles increases, which increases the resistance when passing through the filter screen, thus making the filter screen more effective.

[0012] 2. This utility model, by setting up a purification mechanism, can filter exhaust gas through the filter screen in the purification mechanism. The combination of the rotating plate and the clamping plate makes the purification mechanism easy to disassemble, thus making it easier to clean the filter screen. Attached Figure Description

[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: Figure 1-5 As shown, this utility model provides an environmental protection device for purifying waste gas, including a housing 1. The housing 1 serves as a protective shell and can also support the device. An air inlet 4 and an air outlet 5 are respectively opened at both ends of the housing 1. The air inlet 4 can draw waste gas into the housing 1. A suction fan 41 is fixedly installed inside both the air inlet 4 and the air outlet 5. The suction fan 41 can absorb and discharge the waste gas.

[0022] A humidification mechanism 2 is installed inside the housing 1 on the side near the air inlet 4. The humidification mechanism 2 can increase the humidity in the exhaust gas, thereby increasing the particle size of the exhaust gas particles. A purification mechanism 3 is installed inside the housing 1 on the side near the air outlet 5. The purification mechanism 3 can purify the exhaust gas.

[0023] The humidification mechanism 2 includes a water tank 21, which can hold clean water. The water tank 21 is fixedly installed on the top surface of the housing 1 to prevent the water tank 21 from falling off. Water pipes 22 are connected to both sides of the water tank 21, and the water pipes 22 can transport clean water.

[0024] A support rod 23 is fixedly installed on the upper inner wall of the housing 1. The support rod 23 is used as a fixing component. Two atomizing nozzles 24 are fixedly installed at the bottom end of the support rod 23. The atomizing nozzles 24 can convert water into mist and spray it out. The atomizing nozzles 24 are mirror-distributed on both sides of the upper inner wall of the housing 1 to make the humidification effect of the exhaust gas better. The bottom ends of the two water supply pipes 22 are respectively connected to the two atomizing nozzles 24, and the water supply pipes 22 deliver water to the inside of the atomizing nozzles 24.

[0025] A water collection tank 25 is provided on the lower inner wall of the shell 1. The water collection tank 25 can collect excess water. A water outlet 27 is provided on the bottom surface of the water collection tank 25, and water is discharged through the water outlet 27. The bottom end of the water outlet 27 is connected to a water outlet pipe 26, which extends to the lower part of the shell 1. The water outlet pipe 26 is connected to a collection pipe to collect and recycle excess water.

[0026] The purification mechanism 3 includes a sealing plate 32, which is movably inserted into one side of the housing 1. The sealing plate 32 can reduce the gap between the purification mechanism 3 and the housing 1, thereby improving the sealing performance of the housing 1 and preventing exhaust gas from leaking out.

[0027] Multiple filters 31 are fixedly installed on one side of the sealing plate 32. The filters 31 are existing technology and can filter waste particles in the exhaust gas. The sides of the multiple filters 31 are all attached to the inner wall of the housing 1 to prevent exhaust gas leakage.

[0028] A fixing plate 34 is fixedly installed on the side of the sealing plate 32 facing away from the filter screen 31. The fixing plate 34 is attached to the outer surface of the housing 1. Multiple clamping plates 33 are fixedly installed on both sides of the fixing plate 34. The clamping plates 33 can fix the fixing plate 34. The multiple clamping plates 33 are distributed in a rectangular array, which makes the fixing effect of the clamping plates 33 better.

[0029] Multiple fixing rods 35 are fixedly installed on one side of the housing 1. The fixing rods 35 are cylindrical. Each fixing rod 35 has a mirror-distributed spring 36 fixedly installed inside. The spring 36 can adjust the rotation block 39 to rotate. The fixing rod 35 has mirror-distributed grooves 38 inside. Two springs 36 are fixedly installed on the inner wall of the two grooves 38 that are close to each other to prevent the springs 36 from falling off.

[0030] Two rotating blocks 39 are fixedly installed at opposite ends of two springs 36. The rotating blocks 39 can rotate through the springs 36. Both rotating blocks 39 are rotatably installed inside the fixed rod 35. A rotating shaft 37 is rotatably inserted into one side of the rotating block 39. The rotating shaft 37 is fixedly installed inside the fixed rod 35, so that the rotating block 39 can rotate inside the fixed rod 35 through the rotating shaft 37. The clamping plate 33 is clamped on the outer surface of the fixed rod 35. The rotating block 39 can clamp the clamping plate 33 to fix the fixed plate 34.

[0031] Working principle: First, install the equipment in a suitable location, connect the air inlet 4 to the exhaust gas pipe, the air outlet 5 to the exhaust gas pipe, and the water outlet 26 to the water flow recovery pipe.

[0032] Then, the suction fan 41 is started to draw the exhaust gas into the housing 1, and the humidification mechanism 2 is started to allow clean water to enter the water supply pipe 22 from the water tank 21 and then enter the atomizing nozzle 24 at the bottom of the support rod 23 through the water supply pipe 22. After passing through the atomizing nozzle 24, the water is converted into a mist and sprayed out, which can increase the humidity in the exhaust gas, causing the waste particles in the exhaust gas to condense and increase their volume, making it easier for the filter screen 31 in the subsequent purification mechanism 3 to filter them.

[0033] Meanwhile, excess water will fall into the water collection tank 25 at the bottom of the shell 1, and enter the water outlet pipe 26 through the water outlet 27, and be recycled through the recycling pipe to reduce waste.

[0034] When the surface of the filter screen 31 becomes clogged and the purification effect is reduced, multiple rotating blocks 39 can be pressed to release the rotating blocks 39 from the locking plate 33. Then, the sealing plate 32 and the filter screen 31 can be disassembled and cleaned through the fixing plate 34.

[0035] When the filter screen 31 needs to be installed, the filter screen 31 together with the sealing plate 32 can be inserted into one side of the housing 1, so that the sealing plate 32 fits tightly with the housing 1. At the same time, the fixing plate 34 will drive the clamping plate 33 to fit the fixing rod 35 and squeeze the rotating block 39, so that the rotating block 39 squeezes the spring 36 and rotates in the groove 38 through the rotating shaft 37. When the clamping plate 33 passes the rotating block 39, the spring 36 will drive the rotating block 39 to reset, so that the rotating block 39 engages with the clamping plate 33 and fixes the fixing plate 34.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
