Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, specifically to a device for purifying and treating harmful gases in a production workshop. Background Technology
[0002] In the preparation of butyl rubber sound insulation pads, cutting is a necessary process to optimize material redundancy and edge quality. The existing three methods, CNC waterjet cutting, mechanical cutting, and thermal cutting, each have their limitations: waterjet cutting has low efficiency and high energy consumption, and the impact of water flow can easily cause edge wrinkles; mechanical cutting is prone to "drag" deformation due to the high elasticity of the material, the blade is prone to adhesion and dulling, complex shapes require customized molds, which are costly and have poor adaptability.
[0003] Thermal fusion cutting melts materials at high temperatures without the application of external mechanical force, resulting in good edge self-sealing performance and improved sound insulation. However, the high temperatures release irritating gases such as sulfur compounds. While existing technologies use fans to expel these harmful gases, there is a time lag between gas generation and exhaust. By the time the cutting process begins, the gas has already spread to the operating area, meaning workers have already inhaled the harmful gases before the fans are even turned on. Even subsequent treatment cannot completely prevent health hazards. The technological advantages of thermal fusion cutting lead to rapid gas release, creating a risk. Existing terminal exhaust systems, due to their passive collection characteristics, cannot prevent workers from being exposed to harmful gases during the critical window period, thus endangering their health.
[0004] Therefore, this utility model provides a device for purifying and treating harmful gases in a production workshop to solve the above-mentioned problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a harmful gas purification and treatment device for production workshops, which solves the aforementioned problems.

The treatment mechanism includes a treatment tank containing a potassium permanganate solution. A second porous plate is fixedly connected to the inner side wall of the treatment tank, and an aeration pipe is installed on the second porous plate. A first porous plate is fixedly connected to the aeration pipe.
[0007] Preferably, the exhaust mechanism includes a three-way valve, a manifold, and an exhaust port. The manifold is connected to the exhaust port via a pipe, and the exhaust port is located in various parts of the factory.
[0008] Preferably, the exhaust mechanism further includes an exhaust port, the three-way valve is connected to the manifold, the side end of the three-way valve is connected to the fan through a pipe, and the exhaust port is placed inside the housing.
[0009] Preferably, a distributor is provided inside the processing tank, and a third perforated plate is fixedly connected to the distributor.
[0010] Preferably, the processing mechanism further includes a dust filter, on which a first filter screen is fixedly connected, and a plurality of cylindrical filter screens are disposed on the first filter screen.
[0011] Preferably, the dust filter is connected to the treatment tank via a pipe, the treatment tank is equipped with a pH adjustment device, and the treatment tank outlet is equipped with a hydrogen sulfide sensor and a first valve.
[0012] Preferably, the outer casing is relatively sealed, and the one-way air intake structure includes a pipe, a fan, and a one-way air valve.
[0013] Preferably, the first filter screen is a coarse filter, and the cylindrical filter screen is a fine filter.
[0014] Beneficial effects This utility model provides a device for purifying and treating harmful gases in a production workshop. Compared with the prior art, it has the following advantages: (1) A production workshop harmful gas purification and treatment device, wherein the outer shell is connected to the exhaust port through a one-way air intake mechanism. When cutting, the inside is formed by negative pressure, and the gas is instantly adsorbed into the exhaust mechanism to avoid the positive pressure spreading to the operating area and causing harm to the health of the workers.
[0015] (2) A production workshop harmful gas purification and treatment device, which intercepts most of the dust through the first filter screen and the cylindrical filter screen in the dust filter, prevents the aeration pipe from being blocked, ensures stable aeration efficiency, avoids the decline in treatment performance due to the accumulation of impurities, and aerates the gas evenly through the aeration pipe and the first perforated plate to increase the contact area. Then, the gas is dispersed again through the distributor in conjunction with the third perforated plate, so that the gas can come into contact with the potassium permanganate solution.

[0018] 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.
[0019] Example 1: Please see Figures 1-6 A production workshop harmful gas purification and treatment device includes an outer shell 1, an exhaust mechanism and a treatment mechanism. A thermal cutting device 2 is installed inside the outer shell 1, and a one-way air intake mechanism is provided in the outer shell 1. The treatment mechanism includes a treatment tank 49, which contains a potassium permanganate solution. A second porous plate 46 is fixedly connected to the inner wall of the treatment tank 49. An aeration pipe 44 is installed on the second porous plate 46, and a first porous plate 45 is fixedly connected to the aeration pipe 44.
[0020] The exhaust system includes a three-way valve 32, a manifold 34, and an exhaust port 35. The manifold 34 is connected to the exhaust port 35 via a pipe, and the exhaust ports 35 are located in various parts of the factory.
[0021] The exhaust mechanism also includes an exhaust port 31, a three-way valve 32 connected to a manifold 34, and the side of the three-way valve 32 connected to a fan 33 via a pipe. The exhaust port 31 is placed inside the housing 1.
[0022] A distributor 48 is installed inside the processing tank 49, and a third perforated plate 47 is fixedly connected to the distributor 48.
[0023] The processing mechanism also includes a dust filter 41, on which a first filter screen 42 is fixedly connected, and a plurality of cylindrical filter screens 43 are provided on the first filter screen 42.
[0024] The dust filter 41 is connected to the treatment tank 49 through a pipe. The treatment tank 49 is equipped with a pH adjustment device, and the outlet of the treatment tank 49 is equipped with a hydrogen sulfide sensor and a first valve.
[0025] Work process: Through exhaust ports 35 located in various locations, and in conjunction with fans 33, the gas from the factory is transported through pipelines to dust filters 41 for filtration.
[0026] Open the exhaust port 31, start the fan, and exhaust air into the housing 1. When the butyl rubber sound insulation pad is cut inside the housing 1, the housing 1 is relatively sealed to prevent the gas generated inside the housing 1 from being discharged to the outside. When gas is generated during the cutting process, open the exhaust port 31 to discharge the gas inside the housing 1. The gas is then passed through the pipe via the exhaust port 31, through the three-way valve 32 and the fan 33, and enters the dust filter 41. After being filtered by the filter screen 42 and the cylindrical filter screen 43 inside the dust filter 41, the gas is prevented from clogging the subsequent aeration pipe 44. The filtered gas then enters the aeration pipe 44 through the pipeline system, where aeration allows the gas to fully react with the potassium permanganate solution. 5H2S+2KMnO4+3H2SO4→5S↓+2MnSO4+K2SO4+8H2O.
[0027] When the gas passes through the distributor 48 again, the distributor 48 disperses the gas a second time to enhance the reaction.
[0028] The gas is further dispersed using distributor 48, and then the treated gas is transported to the discharge area through pipeline.
[0029] Dust filter 41 and treatment tank 49 are regularly maintained and cleaned.
