Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology in artificial leather production, specifically to a waste gas treatment device for artificial leather production. Background Technology

[0002] Environmental protection and resource recycling have become important research topics for industrial sustainable development, especially in the chemical industry, such as leather goods production. Since the production of artificial leather inevitably generates large amounts of waste gas containing dimethylamide (DMF), toluene, methyl ethyl ketone (MEK), and xylene, direct discharge through exhaust fans in the workshop would severely pollute the environment and endanger human health.

[0003] The artificial leather production waste gas treatment device disclosed in patent number "CN219744300U" includes a housing, a protective box provided on the inner bottom wall of the housing, a first motor provided inside the protective box, a connecting shaft provided at one end of the output shaft of the first motor, a connecting ring provided at the end of the connecting shaft away from the output shaft of the first motor, an agitator provided on the outer surface of the connecting ring, a fixed chamber provided on the lower surface of the housing, a collection chamber slidably connected inside the fixed chamber, and a control handle provided on the outer surface of the collection chamber. This device improves the waste gas treatment effect and facilitates quick replacement of waste gas treatment accessories.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] Existing waste gas treatment devices have many problems in treating waste gas from artificial leather production. Some devices use a single treatment process, such as using only activated carbon adsorption. However, the adsorption capacity of activated carbon is limited, and the single treatment method reduces the effectiveness of waste gas treatment, resulting in insufficient removal of impurities in the emitted gas. Utility Model Content

[0006] The purpose of this invention is to provide a waste gas treatment device for artificial leather production, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A waste gas treatment device for artificial leather production includes an air inlet box and a treatment box. The air inlet box and the treatment box are connected. An air inlet pipe is connected to one side of the air inlet box. A connecting pipe is provided between the air inlet box and the treatment box. Multiple sets of filter plates are provided inside the air inlet box.

[0009] The processing box includes an outer shell and an inner box. The inner box is located inside the outer shell. A base is provided on the bottom surface of the outer shell. The base is a heating base. A heating wire is provided inside the outer shell. A connecting pipe extends through the outer shell into the inner box. An activated carbon adsorption chamber is provided at the bottom of the inner box. A filter plate assembly is provided in the middle of the inner box. Two sets of exhaust port assemblies are symmetrically arranged on both sides of the top of the inner box.

[0010] Preferably, a sealing flange is provided at one end of the air intake pipe, and an air extraction valve is provided on the connecting pipe. The air extraction valve is used to extract the gas inside the air intake box and discharge it into the inner box for filtration.

[0011] Preferably, the air intake box has sealing slots equidistantly opened on one side, and multiple sets of filter plates are respectively inserted through the sealing slots and extend into the air intake box. Three sets of sealing slots are matched with the filter plates.

[0012] Each of the three filter plates is fixedly connected to a handle on one side, and a sealing strip is provided at the point where the inner side of the handle fits into the sealing groove.

[0013] Preferably, the filter plate is a glass fiber filter plate, and the filter plate has a uniformly distributed, equidistantly spaced, interwoven pore structure, which facilitates the effective interception of particulate matter in the artificial leather waste and prevents particulate matter from entering the subsequent processing unit and affecting the operation of the equipment.

[0014] Preferably, the top of the inner chamber is provided with a cover, and a detection alarm device is provided on one side of the top of the cover. Each exhaust port assembly is provided with a monitoring probe for monitoring the concentration of volatile compounds. The detection alarm device is connected to the monitoring probe inside the exhaust port assembly. When the monitoring data exceeds the standard, the system module will cause the detection alarm device to automatically sound an alarm.

[0015] Preferably, the filter plate assembly includes a base and a fine filter plate. The base is fixedly connected to the inner wall of the inner chamber. The fine filter plate is snapped onto the upper surface of the base. The upper surface of the base has a slot. The bottom surface of the fine filter plate is fixedly connected to a locking block, which engages with the slot. The fine filter plate contains a catalyst component to facilitate a more thorough decomposition of the odor from the evaporated products attached to the activated carbon in the gas.

[0016] Preferably, the exhaust port assembly includes an exhaust pipe and filter blocks sequentially disposed inside the exhaust pipe. The exhaust pipe is symmetrically installed and connected to both sides of the top of the inner box. The filter blocks are configured as metal sintered filter blocks, which can perform final filtration of particulate matter contained in the artificial leather gas and discharge it through the exhaust pipe.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By matching the air intake box and the treatment box, the waste gas generated in the production of artificial leather first enters through the air intake box and then is discharged into the treatment box through the connecting pipe. The multiple sets of filter plates inside the air intake box can perform primary filtration of the gas. The filter plates are made of glass fiber filter plates, which have a pore structure formed by mutual interlacing evenly distributed and equidistant openings. This facilitates the effective interception of particulate matter in the waste of artificial leather and prevents particulate matter from entering the subsequent treatment unit and affecting the operation of the equipment.

[0019] 2. The inner chamber is heated by the heating base and the outer shell of the treatment box. The pre-treated waste gas is heated to the temperature required for the catalytic reaction. Then, the activated carbon components inside the activated carbon adsorption chamber work with the filter plate assembly to generate strong oxidizing free radicals, which facilitates a more thorough decomposition of the odors in the gas after the activated carbon adheres to it, effectively removing odorous gases and achieving deep purification of the gas.

[0020] 3. The exhaust port assembly is connected to the deep purification unit inside the inner chamber at one end and to the atmosphere at the other end. An online monitoring device is installed inside to monitor various indicators of the exhaust gas in real time, such as the concentration of volatile organic compounds and particulate matter. When the monitoring data exceeds the standard, the system will automatically alarm through the detection alarm device set on the top of the chamber cover and adjust the processing parameters to ensure stable operation of the device and improve processing efficiency and reliability.
