[0002] Petrochemical companies generate a large amount of exhaust gas during production. This exhaust gas contains various components, such as sulfur dioxide and nitrogen oxides. These components can harm the environment and also pose certain risks to human health. Therefore, exhaust gas needs to be treated before it is released.

[0003] Currently, most exhaust gas treatment methods use spraying, where liquid captures particles in the exhaust gas, forming larger particles that then fall off. However, in actual use, with the introduction of a large amount of exhaust gas, the number of particles sprayed off by the spray increases. A large number of particles falling onto the filter plate can easily clog the filter plate, affecting its normal operation. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Example

[0033] Reference Figures 1-7This utility model provides a technical solution: an exhaust gas treatment device, including a housing 1, a replacement mechanism 3 and a spraying mechanism 4, and a liquid storage tank 2 installed outside the housing 1. The replacement mechanism 3 includes a support frame 31, which is installed inside the housing 1 and has a groove 311. A filter plate 32 is installed inside the housing 1, and a protective plate 321 is installed outside the filter plate 32. A clamping member 33 is installed outside the housing 1, with one end of the clamping member 33 fitting against the outer surface of the protective plate 321. The spraying mechanism 4 is located outside the housing 1.

[0034] By setting a movable receiving plate 8 inside the housing 1, on which a filter plate 32 is installed, and a protective plate 321 is installed at the outer end of the receiving plate 8, the receiving plate 8 can be pulled out from inside the housing 1 by pulling the protective plate 321 during use, and the filter plate 32 can be moved out of the housing 1. This makes it convenient to replace the filter plate 32, effectively replacing the traditional method of cleaning the filter plate 32 and ensuring that the equipment can be used normally.

[0035] In a preferred embodiment, the spraying mechanism 4 includes a liquid pump 41, a liquid outlet pipe 42, a liquid collection tank 43, and spray heads 44. A positioning plate 5 is fixedly installed on the outer surface of the housing 1, and the liquid pump 41 is stably installed on the upper surface of the positioning plate 5. The liquid outlet end of the liquid pump 41 is equipped with a liquid outlet pipe 42, one end of which extends into the interior of the housing 1. The liquid collection tank 43 is fixedly installed inside the housing 1, and one end of the liquid outlet pipe 42 extends into the interior of the liquid collection tank 43, connecting the interior of the liquid collection tank 43 with the interior of the liquid outlet pipe 42. Several spray heads 44 are also provided at the bottom of the liquid collection tank 43. A pipe is stably installed at the liquid inlet end of the liquid pump 41, one end of which extends into the interior of the liquid storage tank 2 for extracting the spray liquid and realizing the recycling of the spray liquid.

[0036] In use, the spray liquid inside the storage tank 2 is extracted by the pump 41. The spray liquid is transported from the inside of the pipeline to the inside of the outlet pipe 42. Several spray heads 44 are installed at the bottom of the collection chamber 43 and are connected to the inside of the collection chamber 43. After the spray liquid is transported into the collection chamber 43, it will be distributed to the inside of each spray head 44 and sprayed out from the inside of the spray head 44. The nozzles of the spray heads 44 in this device have very small apertures, which can make the liquid spray out in the form of mist to treat the particles in the exhaust gas and meet the requirements of use.

[0037] The filter plate 32 separates particles from the spray liquid. However, with prolonged use, the pores on the filter plate 32 are prone to clogging. To ensure normal operation, a roller 6 is rotatably installed inside the groove 311, and a connecting rod 7 is rotatably installed on the roller 6. The outer surface of the connecting rod 7 is fixedly connected to the receiving plate 8, and the filter plate 32 is bolted to the upper surface of the receiving plate 8. A support frame 31 is installed on the inner wall of the housing 1, and the filter plate 32 is mounted on the support frame 31. The outer side of the filter plate 32 fits against the inner wall of the housing 1 to prevent particles from falling through the gaps to the bottom of the housing 1. The roller 6 rolls on the support frame 31, allowing the filter plate 32 to be pulled out from inside the housing 1 for replacement. Since the filter plate 32 is bolted, the bolts can be loosened directly to remove the old filter plate 32 and replace it with a new one.

[0038] During normal use, to ensure that the filter plate 32 can be used inside the housing 1, a rectangular plate 9 is fixedly installed on the outer surface of the housing 1. The clamping member 33 is rotatably installed below the rectangular plate 9. A round rod 10 is fixedly installed at the upper end of the clamping member 33. The outer surface of the round rod 10 is provided with a insertion hole 11, and a through hole 12 is provided on the upper surface of the rectangular plate 9. The diameter of the through hole 12 is the same as the diameter of the insertion hole 11. An insertion rod 13 is inserted into the through hole 12. One end of the insertion rod 13 is inserted into the inside of the insertion hole 11 to position the round rod 10 and thus position the clamping member 33.

[0039] Push the receiving plate 8 into the interior of the housing 1 so that the protective plate 321 is flush with the outer surface of the housing 1. Then rotate the clamping member 33 downwards. As the clamping member 33 rotates, it will also drive the round rod 10 to rotate, moving the insertion hole 11 on the round rod 10 to correspond to the position of the through hole 12. At this time, the clamping member 33 will be in close contact with the outer surface of the protective plate 321. Then, the insertion rod 13 passes through the through hole 12 and is inserted into the insertion hole 11. This can position the round rod 10 and the clamping member 33. The clamping member 33 squeezes and positions the protective plate 321, so that the filter plate 32 can be used stably inside the housing 1. Conversely, if the clamping member 33 is reversed, the protective plate 321 can be pulled and the filter plate 32 can be pulled out from the interior of the housing 1, making it convenient to replace the filter plate 32 and meet the usage requirements.

[0040] Specifically, the working process or working principle of an exhaust gas treatment device is as follows: Currently, most exhaust gas treatment methods use spraying to capture particles in the exhaust gas, forming larger particles that then fall. However, in actual use, as a large amount of exhaust gas is introduced, the number of particles sprayed and falling from the exhaust gas increases. A large number of particles falling on the filter plate 32 can easily clog the filter plate 32, affecting its normal use. Therefore, this device was designed to solve this problem.

[0041] This device can replace the filter plate 32 inside the housing 1. Compared with the existing methods of cleaning the filter plate 32, this device can improve the performance of the filter plate 32 and avoid clogging of the holes on the filter plate 32, which would affect the filtration effect. Specifically, the device is connected to an external power source, and the exhaust gas is introduced into the housing 1 through the inlet pipe. At the same time, the liquid pump 41 extracts the spray liquid from the storage tank 2. The spray liquid is transported to the inside of the collection chamber 43 and sprayed out from the spray head 44. The spray head 44 is located at the upper part of the housing 1 and is positioned in the collection chamber 43 by a connecting rod to ensure stable use of the collection chamber 43. This allows the spray head 44 to be used stably, and the liquid sprayed from the spray head 44 will spray the exhaust gas.

[0042] Since there are many particles in the exhaust gas, the spray liquid can remove these particles. A water film will be coated on the outer surface of the particles, which will adsorb other suspended particles, increasing the volume and weight of the particles. The particles will then fall naturally onto the filter plate 32, where they will remain. The liquid will then pass through the filter plate 32 and enter the bottom of the housing 1, thus treating the particles in the exhaust gas.

[0043] The device has an inclined plate installed at the bottom of the inner side of the box 1, and several water inlets are provided on the inner wall of the box 1. Water inlets are installed inside the water inlets, which can recycle the spray liquid collected inside the box 1 into the storage tank 2, so as to recycle the spray liquid and save resources.

[0044] After a period of use, the holes on the filter plate 32 are prone to clogging. Therefore, during use, the connecting rod 13 can be pulled out from the inside of the round rod 10 so that the round rod 10 can rotate normally. Then, the clamping member 33 can be rotated to release the clamping member 33 from the squeezing and positioning of the protective plate 321. The protective plate 321 can be pulled to move, and the filter plate 32 can be taken out from the inside of the housing 1. The bolts on the receiving plate 8 can be unscrewed to remove the filter plate 32 and a new filter plate 32 can be placed to ensure the normal use of the equipment.
