Description

Technical Field

[0001] This utility model relates to the field of chemical waste gas treatment technology, specifically a waste gas treatment device for chemical raw material processing. Background Technology

[0002] Chemical waste gas refers to the toxic and harmful gases discharged from chemical plants during chemical production. Chemical waste gas often contains a wide variety of pollutants with complex physical and chemical properties and varying degrees of toxicity, seriously polluting the environment and affecting human health. The composition of chemical waste gas varies greatly among different chemical production industries. For example, waste gas from the chlor-alkali industry mainly contains chlorine, hydrogen chloride, vinyl chloride, mercury, and acetylene, while waste gas from the nitrogen fertilizer industry mainly contains nitrogen oxides, urea dust, carbon monoxide, ammonia, sulfur dioxide, and methane.

[0003] In related technologies, chemical waste gas treatment often involves a large amount of dust particles in the waste gas. These particles can easily clog pipes and the inside of treatment equipment, causing damage to the equipment and affecting its waste gas treatment efficiency.

[0004] Therefore, it is necessary to provide a waste gas treatment device for chemical raw material processing to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a waste gas treatment device for chemical raw material processing, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste gas treatment device for chemical raw material processing, comprising a treatment box, a first screen being provided inside the treatment box, a second screen being provided at the bottom of the first screen, a cleaning component being arranged horizontally inside the treatment box, a filter collection component being provided on the right side of the treatment box, an air inlet pipe being connected to the top of the treatment box, and an exhaust pipe being provided at the bottom of the treatment box.

[0007] Preferably, the cleaning assembly includes two reciprocating screws rotatably connected inside the processing chamber. Each reciprocating screw has a threaded sleeve on its surface, and an exhaust pipe is fixedly connected to the bottom of the sleeve. A telescopic pipe connects to the top of the exhaust pipe. A synchronous pulley is fixedly connected to the left side of the reciprocating screw extending through to the left side of the processing chamber. A synchronous belt meshing with the synchronous pulley is provided on the left side of the processing chamber. A servo motor is fixedly connected to the left side of the reciprocating screw.

[0008] Preferably, the filter collection assembly includes a collection box, which is fixedly connected to the right side of the processing box. A filter screen is installed inside the collection box, and a fan is connected to the right side of the collection box. The right side of the telescopic pipe is connected to the left side of the processing box.

[0009] Preferably, a cleaning brush is fixedly connected to the bottom of the exhaust pipe, and the number of cleaning brushes is several.

[0010] Preferably, a support plate is fixedly connected to the bottom of the servo motor, and the bottom of the support plate is fixedly connected to the left side of the processing box.

[0011] Preferably, the bottom of the inner wall of the collection box is fixedly connected with a partition, and the number of partitions is several.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model involves connecting exhaust gas into an intake pipe, which then enters the interior of a treatment chamber. Impurities and dust are filtered through a first and second screen, isolating the exhaust gas. The user then activates a fan, which draws air from the treatment chamber, creating a negative pressure environment. The treatment chamber then uses a telescopic pipe to extract air from the exhaust duct, drawing dust from the tops of the first and second screens. A servo motor is then activated, driving a reciprocating screw to rotate. This screw drives a synchronous pulley, which in turn drives a synchronous belt, causing both screws to rotate simultaneously. The reciprocating screws move the sleeve back and forth, allowing the exhaust duct to move left and right to extract dust, thus achieving the effect of pre-treating the exhaust gas.

[0017] Please see Figure 1 - The cleaning component 4 includes a reciprocating screw 41, which is rotatably connected inside the processing box 1. There are two reciprocating screws 41. The surface of the reciprocating screw 41 is threaded with a screw sleeve 42. The bottom of the screw sleeve 42 is fixedly connected to an exhaust pipe 43. The top of the exhaust pipe 43 is connected to a telescopic pipe 44. The left side of the reciprocating screw (41) extends through to the left side of the processing box 1 and is fixedly connected to a synchronous pulley 45. A synchronous belt 46 that meshes with the synchronous pulley 45 is provided on the left side of the processing box 1. A servo motor 47 is fixedly connected to the left side of the reciprocating screw 41.

[0018] Furthermore, with the cleaning component 4 in place, users can easily and thoroughly clean the tops of the first screen 2 and the second screen 3, effectively collecting accumulated dust. This process not only helps prevent dust from adhering to the screens but also significantly improves filtration efficiency, ensuring optimal performance of the equipment and providing great convenience to users.

[0019] Please see Figure 3 The filter collection assembly 5 includes a collection box 51, which is fixedly connected to the right side of the processing box 1. A filter screen 52 is installed inside the collection box 51. A fan 53 is connected to the right side of the collection box 51, and the right side of the telescopic pipe 44 is connected to the left side of the processing box 1.

[0020] Furthermore, the well-configured filter collection component 5 can easily collect the dust generated during the filtration process, thereby preventing the dust from spreading in the air and preventing secondary pollution. This design not only improves cleaning efficiency but also greatly simplifies subsequent cleaning work, bringing great convenience to users.

[0021] Please see Figure 5 A cleaning brush 8 is fixedly connected to the bottom of the exhaust pipe 43, and there are several cleaning brushes 8.

[0022] Furthermore, by setting up the cleaning brush 8, users can easily clean the tops of the first screen 2 and the second screen 3 regularly, effectively avoiding the problem of dust accumulation.

[0026] Furthermore, the reasonably designed partition 10 can effectively support and limit the outer side of the filter screen 52, ensuring high support efficiency. This design effectively prevents the filter screen 52 from shaking during use, thereby ensuring the stability and reliability of the filtration effect and bringing great convenience to the user.

[0027] The specific implementation process of this utility model is as follows: When it is necessary to isolate particles and dust in the exhaust gas, the exhaust gas is connected to the air inlet pipe 6 and then enters the interior of the treatment box 1. The impurities and dust are filtered through the first screen 2 and the second screen 3, which can isolate the impurities in the exhaust gas. Then, the user starts the fan 53, which draws air from the inside of the treatment box 1, making the inside of the treatment box 1 a negative pressure state. The treatment box 1 draws air from the inside of the exhaust pipe 43 through the telescopic pipe 44. The dust on the top of the first screen 2 and the second screen 3 can be drawn down through the exhaust pipe 43. Then, the servo motor 47 is started, which drives the reciprocating screw 41 to rotate. The reciprocating screw 41 drives the synchronous wheel 45 to rotate, and the synchronous wheel 45 drives the synchronous belt 46 to rotate, so that the two reciprocating screws 41 rotate simultaneously. The reciprocating screws 41 drive the screw sleeve 42 to move back and forth, so that the exhaust pipe 43 can move left and right to draw dust, thereby achieving the effect of pre-treating the exhaust gas.
