Description

Technical Field

[0001] This utility model relates to the field of gas ventilation and filtration technology, and in particular to a gas ventilation and filtration device. Background Technology

[0002] In the chemical production process, a mixture of gases containing various pollutants such as dust, corrosive gases, and volatile organic compounds is continuously generated. If not treated in a timely and effective manner, it will not only pollute the workshop working environment and endanger the health of operators, but may also cause safety accidents such as explosions and poisoning due to gas leaks. Therefore, it is necessary to purify these gases through special ventilation and filtration devices, which is one of the core requirements in the field of chemical safety engineering.

[0003] Chemical production often requires switching between different process stages, which in turn changes the types of chemical gases to be treated. Existing absorption devices typically have fixed absorption components with the absorbent material directly filling the interior. Replacing the absorbent material to adapt to new gas treatment needs requires disassembling the main unit and interrupting the overall ventilation system. This is not only cumbersome and time-consuming but also leads to production downtime and increased operating costs. To overcome these disadvantages, this invention provides a gas ventilation and filtration device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gas ventilation and filtration device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a gas ventilation and filtration device, including a hanging plate, a filter chamber fixedly connected to one side of the hanging plate, an exhaust fan fixedly connected to the air inlet of the filter chamber, a preliminary filtration component provided on one side of the filter chamber, a slide rail fixedly connected to one side of the hanging plate, a plurality of sliders slidably connected on the slide rail, a first support plate fixedly connected to one side of the sliders, a second support plate provided on one side of the first support plate, an absorption chamber fixedly connected to one side of the second support plate, fixing components provided at the four corners of one side of the first support plate, a connecting component provided at the air inlet of the absorption chamber, hanging components provided on both sides of the hanging plate and both sides of the slide rail, a connecting plate fixedly connected to one side of the first support plate, and a second handle fixedly connected to one side of the first support plate.

[0006] Furthermore, the preliminary filtration assembly includes several slots formed on one side of the filtration chamber, on which a filter plate is slidably connected, and on one side of the filter plate a first handle is fixedly connected.

[0007] Furthermore, the fixing component includes first threaded holes at the four corners of one side of the first support plate, and second threaded holes at the four corners of one side of the second support plate. Fixing bolts are threadedly connected to the second threaded holes and the first threaded holes.

[0008] Furthermore, the connecting assembly includes a flange connection between the air inlet of the absorption chamber and the air outlet of the filter chamber, and the air outlet flange of the absorption chamber is connected to a conveying pipe.

[0009] Furthermore, the hanging assembly includes a hanger that is fixedly connected to both sides of the hanging plate and both sides of the slide rail, and a fixing plate is fixedly connected to one side of the hanger.

[0010] Furthermore, a PLC controller is fixedly connected to one side of the filter chamber.

[0011] The beneficial effects of this utility model are:

[0012] In use, this invention allows for precise absorption and filtration of different types of chemical gases by adding materials that absorb different chemical gases to the absorption chamber on the second support plate. When it is necessary to switch the processing target to adapt to different chemical gas filtration requirements, the absorption chamber containing the corresponding absorbent material can be quickly fixed between the filter chamber and the conveying pipeline by sliding the slider on the slide rail and connecting the air inlet of the absorption chamber. This eliminates the need for disassembling and modifying the entire device, greatly improving the device's adaptability to chemical gas filtration under multiple working conditions and reducing the operating and time costs when switching working conditions.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-3 As shown, a gas ventilation and filtration device is disclosed, comprising a hanging plate 1, a filter chamber 2 fixedly connected to one side of the hanging plate 1, an exhaust fan 3 fixedly connected to the air inlet of the filter chamber 2, a preliminary filtration assembly provided on one side of the filter chamber 2, a slide rail 8 fixedly connected to one side of the hanging plate 1, a plurality of sliders 9 slidably connected on the slide rail 8, a first support plate 10 fixedly connected to one side of the sliders 9, a second support plate 12 provided on one side of the first support plate 10, an absorption chamber 14 fixedly connected to one side of the second support plate 12, fixing assemblies provided at the four corners of one side of the first support plate 10, a connecting assembly provided at the air inlet of the absorption chamber 14, hanging assemblies provided on both sides of the hanging plate 1 and both sides of the slide rail 8, a connecting plate 20 fixedly connected to one side of the first support plate 10, and a second handle 19 fixedly connected to one side of the first support plate 10.

[0021] like Figure 1-3 As shown, the preliminary filtration assembly includes several slots 4 opened on one side of the filtration chamber 2, a filter plate 5 slidably connected to the slot 4, and a first handle 6 fixedly connected to one side of the filter plate 5 for preliminary filtration of the gas.

[0022] like Figure 1-3 As shown, the fixing assembly includes first threaded holes 11 at the four corners of one side of the first support plate 10, and second threaded holes 13 at the four corners of one side of the second support plate 12. Fixing bolts 18 are threadedly connected to the second threaded holes 13 and the first threaded holes 11 for fixing the absorption chamber 14.

[0023] like Figure 1-3 As shown, the connecting assembly includes a flange connection between the air inlet of the absorption chamber 14 and the air outlet of the filter chamber 2. The air outlet flange of the absorption chamber 14 is connected to a conveying pipe 15 for connecting the absorption chamber 14 to the filter chamber 2 and the conveying pipe 15.

[0024] like Figure 1-3 As shown, the hanging assembly includes a hanger 16 that is fixedly connected to both sides of the hanging plate 1 and both sides of the slide rail 8. A fixing plate 17 is fixedly connected to one side of the hanger 16 for suspending the device in a designated position.

[0025] like Figure 1-3As shown, a PLC controller 7 is fixedly connected to one side of the filter chamber 2 for controlling the equipment on the device.

[0026] Working principle: When in use, the entire device is first fixed in the designated position in the chemical workshop by the hangers 16 on both sides of the hanging plate 1 and the fixed plate 17 on both sides of the slide rail 8. Then, the exhaust fan 3 at the air inlet of the filter chamber 2 is started. The exhaust fan 3 generates negative pressure to draw the mixed gas containing dust and chemical gases to be treated in the workshop into the filter chamber 2. At the same time, the operating parameters of the device are monitored in real time by the PLC controller 7 on one side of the filter chamber 2.

[0027] During filtration, after the mixed gas enters the filter chamber 2, it first flows through the filter plate 5, which is slidably connected in the slot 4 on one side of the filter chamber 2. The filter plate 5 intercepts dust and particulate impurities in the gas. If the filter plate 5 is clogged due to the accumulation of impurities on its surface after a period of use, the filter plate 5 can be directly pulled out of the slot 4 for cleaning or replacement through the first handle 6 on one side of the filter plate 5. After preliminary dust removal, the gas enters the absorption chamber 14 from the outlet of the filter chamber 2. The absorption chamber 14 is connected to the first support plate 10 through the second support plate 12 and is fixed on the first support plate 10 by the fixing component. The absorption chamber 14 is pre-loaded with the absorbent material corresponding to the chemical gas to be treated. The gas comes into full contact with the absorbent material in the absorption chamber 14 to complete the adsorption and purification of the chemical gas.

[0028] When it is necessary to switch to process different types of chemical gases, first loosen the flange connection between the air inlet of the absorption chamber 14 and the air outlet of the filter chamber 2, as well as the flange connection between the air outlet of the absorption chamber 14 and the conveying pipe 15. Then, push and pull the slider 9 on the slide rail 8 through the second handle 19 on one side of the first support plate 10 to move the absorption chamber 14 containing the current absorbent material away. Then, slide another set of absorption chambers 14 containing the target absorbent material to the corresponding position through the slider 9, and fix them between the filter chamber 2 and the conveying pipe 15 through the flange connection to achieve rapid adaptation of chemical gas filtration under multiple working conditions.

[0029] After absorption and purification, the gas is discharged from the outlet of the absorption chamber 14 through the conveying pipeline 15 to a designated discharge point or recovery system outside the workshop.
