Description

Technical Field

[0001] This utility model relates to the technical field of industrial exhaust gas recovery equipment, specifically a high-efficiency industrial exhaust gas recovery and purification equipment. Background Technology

[0002] Industrial production processes generate a large amount of exhaust gas containing useful components. Recycling and purifying these industrial exhaust gases can not only reduce the pollution caused by direct emissions, but also convert the useful components in the exhaust gases into reusable resources. This meets the industry's development needs for energy conservation, emission reduction, and resource recycling. Therefore, efficient industrial exhaust gas recycling and purification equipment has become an indispensable piece of equipment in the industrial field.

[0003] However, existing industrial exhaust gas recovery and purification equipment has significant shortcomings in practical applications, especially in the adsorbent replacement process. Traditional equipment typically fills the adsorbent directly inside the adsorption tower, which is mostly a vertical structure with fixed internal components. Replacing the adsorbent requires disassembling multiple parts such as the tower end cap and flanges, making the operation cumbersome. This not only requires a lot of manpower and time but also easily damages the equipment's sealing structure during disassembly. Furthermore, the equipment needs to be shut down for a long time during adsorbent replacement, which seriously affects the continuity of industrial exhaust gas treatment and leads to a decrease in overall operating efficiency. Therefore, we propose a high-efficiency industrial exhaust gas recovery and purification equipment. Utility Model Content

[0025] Please see Figure 1-6 This utility model provides a technical solution;

[0026] A high-efficiency industrial exhaust gas recovery and purification device, comprising:

Two sealing devices are provided on the two opposite side walls of the horizontal adsorption tower 4 in an axisymmetrical arrangement. The sealing devices are in contact with the side walls of the pull-out adsorption separation device.

[0028] The pretreatment module 1 and the product collection module 3 are located on opposite sidewalls of the adsorption separation module 2. The pretreatment module 1 and the product collection module 3 are fixedly connected to the sidewalls of the adsorption separation module 2 via flanges. The pretreatment module 1 directly receives the raw industrial exhaust gas and removes impurities that are harmful to subsequent adsorption separation from the exhaust gas, so that the exhaust gas meets the feed standard of the adsorption separation module, avoiding impurities from affecting adsorption efficiency, damaging core components, or contaminating the final product. The product collection module 3 receives the target product after adsorption separation and purification. Its core objective is to achieve stable storage, purity assurance, and convenient supply of the product, while avoiding product waste or secondary pollution.

[0029] Furthermore, the horizontal adsorption tower 4 has a rectangular opening on its side wall, and the rectangular opening corresponds to the pull-out box 5. The two opposite side walls of the horizontal adsorption tower 4 are provided with four internally threaded columns 11 distributed axially symmetrically. The side wall of the horizontal adsorption tower 4 is provided with an inlet / outlet flange pipe at the center of the four internally threaded columns 11.

The pull-out box 5 is pulled out along the guide rod 14 and the adsorbent storage tank 6 is pulled out as a whole through the two handles 20. A new adsorbent storage tank 6 is immediately replaced, allowing it to return to its original position and continue the adsorption separation operation. The removed adsorbent storage tank 6 is convenient for subsequent processing, greatly reducing downtime and improving overall efficiency.

[0035] Furthermore, the top of the pull-out box 5 is provided with a replacement port 19, which is slidably connected to the adsorbent storage tank 6. The two opposite side walls of the pull-out box 5 are provided with rectangular openings that cooperate with the air holes 21.

[0063] Working Principle: Following the correct installation of the high-efficiency industrial exhaust gas recovery and purification equipment as shown in the diagram, the raw industrial exhaust gas first enters the pretreatment module 1. After filtration, drying, and removal of harmful impurities within this module, impurities harmful to subsequent adsorption and separation are removed, ensuring the exhaust gas meets the feed standards of the adsorption and separation module 2. This prevents impurities from affecting adsorption efficiency, damaging core components, or contaminating the final product. The pretreated exhaust gas then enters the horizontal adsorption tower 4 in the adsorption and separation module 2 via flange connections. The inlet and outlet flanges on the two opposite sidewalls of the horizontal adsorption tower 4 are connected to the pretreatment module 1 and the product collection module 3, respectively, ensuring directional delivery of the exhaust gas. After the exhaust gas enters the horizontal adsorption tower 4, it flows through the internal pull-out adsorption separation device. The pull-out box 5 in this device slides against the slide groove 15 at the bottom of the horizontal adsorption tower 4 via a slider 17 at its bottom. The sliding hole 16 on the side wall of the pull-out box 5 slides against the guide rod 14 inside the horizontal adsorption tower 4, ensuring that the pull-out box 5 is stably positioned inside the horizontal adsorption tower 4. The exhaust gas enters the adsorbent storage tank 6 through the rectangular opening corresponding to the side vent 21 on the side of the pull-out box 5, making full contact with the adsorbent inside the tank to achieve adsorption and separation of the target components. During this process, the sealing devices on the two opposite side walls of the horizontal adsorption tower 4 ensure... The exhaust gas is effectively adsorbed and treated. The sealing element 8 in the sealing device is pushed by the fastener 9, and the rubber block 22 on its side wall fits into the sealing groove 18 on the side wall of the pull-out box 5. At the same time, the sealing ring 24 on the outside of the sliding column 23 of the sealing element 8 slides into the cavity 12 on the inner wall of the horizontal adsorption tower 4, thus providing a double seal to prevent exhaust gas leakage. The target product, after adsorption separation and purification, is then transported to the product collection module 3 through the outlet flange pipe of the horizontal adsorption tower 4. The product collection module 3 provides stable storage and purity assurance for the target product, enabling convenient supply while avoiding product waste or secondary pollution. When it is necessary to replace the adsorbent, the protective door 10 is opened and the fastener is rotated to tighten it. The rotating handle at the shaft end of component 9 causes the fastener 9 to move along the internal thread post 11. The mating block 26 at its shaft end rotates within the mating groove 25 of the seal 8, causing the seal 8 to move. This causes the rubber block 22 to retract into the mating groove 13, releasing the limit on the pull-out box 5. Then, the pull-out box 5 is pulled out of the horizontal adsorption tower 4 along the guide rod 14. The adsorbent storage tank 6 is pulled out as a whole through the replacement port 19 and the handle 20 on the side of the adsorbent storage tank 6. After replacing the new adsorbent storage tank 6, the pull-out box 5 is pushed back to its original position. The fastener 9 is rotated in the opposite direction to reset the seal of the seal 8. The protective door 10 is then closed, and the equipment can continue to perform adsorption and separation operations.

[0064] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
