[0001] The utility model relates to the technical field of environmental protection, and particularly relates to an air purification and dust removal device for an acid-making process. Background Technique

[0002] The dust removal device is applied to the air purification and dust removal device supporting the production link in the acid-making process of a chemical plant. This device is used to filter the dust-containing particles in the air, and the clean air after removing the particles is transported to the production equipment through a power system. Usually, it is configured on the inlet pipe network of a large blower.

[0003] For the large blower equipment in the existing acid-making process of chemical plants, generally, a purification and dust removal device in the form of a cube or a funnel is directly installed at the inlet to transport clean air. Although the particle capture effect in the air can be solved, the volumes of these two devices are very large. Therefore, when replacing the filter element, it takes a lot of time, thus affecting the production efficiency. Content of the Utility Model

[0020] Please refer to Figure 1 - Figure 5 The present utility model provides a technical solution: an air purification and dust removal device for an acid-making process, including: a maintenance platform 1; legs 2, the top of the legs 2 is fixedly connected to the bottom of the maintenance platform 1, and the legs 2 are annularly arranged along the central axis of the maintenance platform 1; a dust removal mechanism 3, the bottom of the dust removal mechanism 3 is fixedly connected to the outer wall of the top of the maintenance platform 1; a rain shield 4, the inner wall of the rain shield 4 is fixedly connected to the top of the dust removal mechanism 3 through an air outlet pipe 8, and the air outlet pipe 8 is fixedly connected to the top of the dust removal mechanism 3; a maintenance mechanism 7, the outer wall of the maintenance mechanism 7 is fixedly connected to the inner wall of the air outlet pipe 8; the dust removal mechanism 3 includes a capture net 31, there are four groups of capture nets 31, and the outer wall of each group of capture nets 31 is slidably connected to the outer wall of a fixed cylinder 32. Fixed strips 34 are fixedly connected to the outer walls on both sides of the capture net 31, and a clamping strip 33 is fixedly connected to the outer wall of the fixed strip 34. By clamping the clamping strip 33 into a card slot 75, the position of the capture net 31 is restricted. A pressure detector 6 is fixedly connected to the inner wall of the air outlet pipe 8. The inner wall of the rain shield 4 is fixedly connected to the outer wall of the air outlet pipe 8, and the outer wall of the bottom of the air outlet pipe 8 is fixedly connected to the inner wall of the top of the fixed cylinder 32.

[0021] The maintenance mechanism 7 includes a partition plate 71. A fixed block 74 is fixedly connected to the outer wall of the partition plate 71. A blocking block 73 is slidably connected to the inner wall of the partition plate 71 through a chute 72. The blocking block 73 is used to block the air in the channel from entering the air outlet pipe 8, and the chute 72 is opened in the wall of the partition plate 71. The outer wall of the blocking block 73 is slidably connected to the inner wall of the air outlet pipe 8, and the outer wall of the bottom of the blocking block 73 is slidably connected to the outer wall of the top of the fixed cylinder 32.

[0022] The inner wall of the fixed block 74 is clamped with the outer wall of the clamping strip 33 through a card slot 75, and the card slot 75 is opened in the wall of the fixed block 74. The outer wall of the partition plate 71 is fixedly connected to the inner wall of the fixed cylinder 32. The partition plate 71 divides the fixed cylinder 32 into four groups of channels, and each group of channels does not affect each other. The bottom of the fixed cylinder 32 is fixedly connected to the outer wall of the top of the maintenance platform 1.

[0023] Working principle:

[0024] During use, first fix the entire dust removal device to the ground. Just place all the legs 2 at the bottom of the device on the ground. It should be noted that during the process of placing the legs 2 on the ground, it is necessary to ensure that each leg 2 is in contact with the ground, and no leg 2 should be suspended, to prevent the device from tipping over due to center offset. Then connect the air inlet pipe in the production process to the air outlet pipe 8 at the top of the device. Then the dust removal device can start the dust removal work.

[0025] The outside air enters the device through the dust removal mechanism 3. During the process of the air passing through the dust removal mechanism 3, the impurity in the air is filtered by the capture net 31 in the dust removal mechanism 3. The dust-containing particles in the air are intercepted on the outer wall of the capture net 31 through the capture net 31. The filtered clean air is transported to the production process through the air outlet pipe 8. After using for a period of time, as the dust-containing particles on the surface of the capture net 31 increase, its resistance will increase. At this time, the pressure detector 6 installed on the air outlet pipe 8 sends an electrical signal to the total control, and the total control then prompts the user to clean the dust on the surface of the capture net 31. The user stands on the maintenance platform 1 on the dust removal mechanism 3 and uses the maintenance mechanism 7 to close one of the channels. At this time, remove the capture net 31 on this channel, and rinse it from the inside to the outside with a high-pressure water gun. After cleaning, reinstall the capture net 31 and resume use. Replace them one by one in this way. In order to prevent the surface of the capture net 31 from being drenched by rain, a rain shield 4 is provided on this device, which effectively blocks the situation that the surface of the capture net 31 is covered by dust, mud and water, and reduces the maintenance workload of the air dust removal mechanism 3 during the rainy season.

[0026] When disassembling and assembling the capture net 31, just pull the fixing strips 34 on both sides of the capture net 31, so that the clamping strip 33 slides out of the card slot 75, and the locking of the clamping strip 33 can be released. Then the capture net 31 can be taken out. After cleaning the capture net 31, just align the clamping strips 33 on both sides of the capture net 31 with the card slot 75, and then press the clamping strip 33 forcefully into the fixing block 74, so that the clamping strip 33 slides back into the card slot 75 again, and the position of the capture net 31 can be locked again.

[0027] Before taking out the capture net 31, it is necessary to use the maintenance mechanism 7 to cut off one of the channels. The partition plate 71 in the fixed cylinder 32 divides the fixed cylinder 32 into four groups of channels, and each group of channels does not affect each other. Therefore, when cutting off a certain channel, just slide the stopper 73 in the direction close to the air outlet pipe 8. When the stopper 73 slides into the chute 72, it can block the air in the fixed cylinder 32 from entering the air outlet pipe 8. After cleaning, just slide the stopper 73 in the reverse direction. After the stopper 73 slides out of the chute 72, it can start working again. It should be noted that after the stopper 73 slides out, it is necessary to block the groove on the stopper 73 to prevent the outside air from directly entering the air outlet pipe 8.

[0028] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments in the present utility model without creative efforts shall fall within the scope of protection of the present utility model. Structures, devices, and operation methods not specifically described and explained in the present utility model shall be implemented by conventional means in the art unless otherwise specified and limited.
