Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and more specifically, to a waste gas adsorption and purification treatment device. Background Technology

[0002] Waste gas treatment generated during industrial production is an important part of environmental protection. Waste gas adsorption technology is widely used in waste gas treatment due to its simple operation and stable purification effect. Combining physical adsorption with chemical treatment can further enhance the purification capacity for different types of waste gas. Continuously optimizing the device structure helps to improve the stability of equipment operation and the overall benefits of environmental governance.

[0003] A search revealed that Chinese patent CN213050018U discloses "a waste gas adsorption and purification device, wherein a pipe flange is welded to the upper surface of the waste gas inlet pipe, an inlet regulating component is bolted to the pipe flange, and a valve connecting platform is welded to the upper surface of the inlet pressure regulating valve. First, physical adsorption occurs through an adsorption mesh, followed by secondary adsorption through micro-pores in the adsorption membrane, where the solute on the adsorption membrane has a high affinity for the adsorbed particles in the gas. Simultaneously, chemical adsorption occurs through a chemical solute rod in a chemical adsorption tube, with a chemical solvent placed in the solute storage chamber of the chemical solute rod. This multi-level adsorption method, combining physical and chemical methods, improves the cleanliness of the waste gas purification. Furthermore, the rotation of the booster motor drives the rotation of the rotating shaft, which in turn rotates the booster fan blades, further improving the efficiency of waste gas purification." However, the following defects still exist:

[0004] (1) The single purification structure leads to insufficient waste gas treatment effect. It relies only on adsorption net, adsorption membrane and single chemical solute rod for purification. There is no multi-stage deep treatment structure, which is insufficient for the treatment of complex waste gas, and the purification efficiency and effect are limited.

[0005] (2) Inconvenient component maintenance affects the long-term purification efficiency of the device. The disassembly and assembly of the adsorption net and adsorption membrane rely on a snap-fit ​​structure, and the replacement of the chemical solute rod is cumbersome. There is no convenient quick-disassembly design, which can easily lead to untimely maintenance after the purification components deteriorate, affecting the continuous use effect. To this end, a waste gas adsorption purification treatment device is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a waste gas adsorption and purification device to address the problems of insufficient waste gas treatment effect due to the single purification structure and inconvenient component maintenance affecting the long-term purification efficiency of the device.

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

[0008] The present invention is as follows: a waste gas adsorption and purification treatment device, comprising a treatment box, wherein an adsorption and purification component is installed inside the treatment box, and an airflow control component is installed on the adsorption and purification component.

[0009] The adsorption and purification assembly includes three sets of sliding grooves symmetrically welded to the inner wall of the processing chamber. Each set of sliding grooves has a primary filter layer, an activated carbon adsorption layer, and a molecular sieve purification layer slidably installed in it. An oil mist separation screen is installed at one end of the air inlet of the primary filter layer. A flow guide baffle is installed on the inner wall of the processing chamber. The flow guide baffle is located between the activated carbon adsorption layer and the molecular sieve purification layer. Several flow guide holes are evenly opened on the surface of the flow guide baffle. An air inlet pipe is fixedly connected to one end of the processing chamber, and an air outlet pipe is fixedly connected to the other end of the processing chamber.

[0010] As a preferred technical solution of this utility model, the airflow control component includes an intake regulating valve and a gas flow meter installed on the intake pipe, an outlet regulating valve installed on the outlet pipe, and a pressure relief pipe that is connected through the top of the processing box, with a pressure relief valve installed on the pressure relief pipe.

[0011] As a preferred technical solution of this utility model, the outer wall of the processing box is provided with a disassembly port corresponding to each filter adsorption layer. A sealed box door is hinged to the outside of the disassembly port, and a sealing strip is pasted on the inside of the sealed box door.

[0012] As a preferred technical solution of this utility model, an induced draft fan is installed on the air inlet pipe, and a connecting flange is provided at the end of the air inlet pipe away from the processing box.

[0013] As a preferred technical solution of this utility model, a control box is fixedly installed on the outer wall of the processing box, and a touch screen is installed on the control box.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The adsorption and purification components employ a three-stage progressive structure consisting of a pre-filter layer, an activated carbon adsorption layer, and a molecular sieve purification layer. Combined with a front-end oil mist separation net, it can progressively intercept dust and oil mist particles, and efficiently adsorb organic waste gas, harmful gases, and odor molecules for thorough purification. The multi-layer filter media uses a sliding groove plug-in installation, which is convenient for disassembly, replacement, and maintenance, reducing operating costs. The flow guide baffles and evenly distributed flow guide holes allow waste gas to pass evenly through each adsorption layer, avoiding airflow short-circuiting and local accumulation, making full use of the filter media's adsorption capacity, improving overall purification efficiency and service life, and ensuring that waste gas is discharged in compliance with standards.

[0018] 2. Through the airflow control components, the exhaust gas flow rate and airflow velocity can be flexibly adjusted by cooperating with the inlet and outlet regulating valves, so that the exhaust gas maintains a reasonable residence time in the treatment chamber to ensure sufficient adsorption reaction; the gas flow meter monitors the inlet flow rate in real time, which facilitates precise control of operating parameters and realizes visualization and quantitative management of the purification process; the overall control is sensitive and reliable, which can adapt to different exhaust gas emission volumes and avoid insufficient purification due to excessive flow rate or treatment efficiency due to excessively low flow rate, thereby improving the stability and adaptability of the device operation.

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0026] Example: Figure 1-5 As shown, this embodiment proposes a waste gas adsorption and purification treatment device, including a treatment box 1, an adsorption and purification component 2 installed inside the treatment box 1, and an airflow control component 3 installed on the adsorption and purification component 2.

[0027] like Figure 3As shown, the adsorption purification component 2 includes three sets of sliding grooves 201 symmetrically welded to the inner wall of the treatment chamber 1. Each set of sliding grooves 201 contains a primary filter layer 202, an activated carbon adsorption layer 203, and a molecular sieve purification layer 204, which are slidably installed within it. An oil mist separator 205 is installed at one end of the air inlet of the primary filter layer 202. A flow guide baffle 206 is installed on the inner wall of the treatment chamber 1, located between the activated carbon adsorption layer 203 and the molecular sieve purification layer 204. Several flow guide holes 207 are evenly distributed on the surface of the flow guide baffle 206. An air inlet pipe 208 is fixedly connected to one end of the treatment chamber 1, and an air outlet pipe 209 is fixedly connected to the other end. During use, waste gas is introduced into the treatment chamber 1 through the air inlet pipe 208 and first passes through the oil mist separator 205. Physical coarse filtration effectively traps oil mist and large dust particles in the exhaust gas, providing pretreatment protection and preventing subsequent adsorption layers from being blocked or poisoned. The airflow then passes sequentially through the primary filter layer 202, the activated carbon adsorption layer 203, and the molecular sieve purification layer 204, forming a "three-stage progressive" purification chain: the primary filter layer 202 intercepts fine dust, the activated carbon adsorption layer 203 targets and adsorbs volatile organic compounds and odor molecules, and the molecular sieve purification layer 204 further adsorbs specific small molecule pollutants, achieving deep purification. The flow guide baffle 206 and the evenly distributed flow guide holes 207 constitute a key flow field design, forcing the exhaust gas to diffuse laterally and penetrate each purification layer evenly, avoiding airflow short circuits and filtration blind spots, ensuring that each layer of packing fully utilizes its adsorption efficiency, and finally, the qualified gas is discharged through the exhaust pipe 209.

[0028] like Figure 4 and Figure 5 As shown, the airflow control component 3 includes an intake regulating valve 301 and a gas flow meter 302 installed on the intake pipe 208, an outlet regulating valve 303 installed on the outlet pipe 209, and a pressure relief pipe 304 connected through the top of the treatment chamber 1. A pressure relief valve 305 is installed on the pressure relief pipe 304. In use, the intake regulating valve 301 and the gas flow meter 302 form a closed-loop flow control system. The intake regulating valve 301 can adjust the intake volume according to the upstream pollution conditions, and the gas flow meter 302 monitors the flow data in real time, providing a basis for optimizing process parameters. The outlet regulating valve 303 works with the intake end to control the differential pressure, stabilize the airflow speed and residence time in the treatment chamber 1, and ensure adsorption efficiency. The pressure relief pipe 304 and the pressure relief valve 305 are the core safety mechanisms. When the chamber is overpressurized due to instantaneous pressure abnormality or filter blockage, the pressure relief valve 305 automatically opens to relieve pressure, preventing equipment deformation or sealing failure, and ensuring safe operation of the system under all working conditions.

[0029] like Figure 5As shown, the outer wall of the treatment chamber 1 has a disassembly port 4 corresponding to each filter adsorption layer. A sealing door 5 is hinged to the outside of the disassembly port 4, and a sealing strip 6 is pasted on the inside of the sealing door 5. When it is necessary to replace or clean the filter adsorption layer, the corresponding sealing door 5 can be opened to remove each layer through the disassembly port 4, which is convenient. The sealing strip 6 on the inside of the sealing door 5 can ensure the chamber is sealed, prevent exhaust gas leakage, and ensure the purification effect and operation safety.

[0030] like Figure 1 As shown, an exhaust fan 7 is installed on the intake pipe 208. A connecting flange 8 is provided at the end of the intake pipe 208 away from the treatment box 1. In use, the exhaust fan 7 serves as the power source for the entire purification system, establishing negative pressure suction to drive the exhaust gas to form a stable directional airflow within the box, ensuring that the exhaust gas does not overflow and the purification process is smooth. The connecting flange 8 adopts a standardized interface and is connected to the external exhaust gas pipeline by bolts to achieve an airtight connection. Its flange face sealing gasket can effectively prevent the exhaust gas from escaping at the interface, ensuring the overall sealing and connection strength of the system.

[0031] like Figure 1 As shown, a control box 9 is fixedly installed on the outer wall of the treatment chamber 1. A touch screen display 10 is installed on the control box 9. The induced draft fan 7, the inlet regulating valve 301, the outlet regulating valve 303, and the gas flow meter 302 are all electrically connected to the control box 9. During use, the operating parameters can be set and the equipment operating status and gas flow data can be viewed through the touch screen display 10 on the control box 9. The control box 9 realizes automatic control of the induced draft fan 7, the inlet regulating valve 301, and the outlet regulating valve 303, accurately regulates the operation of the equipment, and improves the purification efficiency.

[0032] like Figure 4 As shown, a drain pipe 11 is connected to the bottom of the treatment box 1. A sealing plug 12 is installed on the drain pipe 11. During use, oil, dust and other impurities generated during the treatment process will be deposited at the bottom of the box. The sealing plug 12 on the drain pipe 11 can be opened periodically to discharge the impurities and avoid accumulation that affects the operation of the equipment and the purification effect. After draining, tighten the plug to ensure that the box is sealed.

[0033] like Figure 3 and Figure 5 As shown, an air distribution net 13 is installed on the side of the oil mist separation net 205 near the air inlet. A handle 14 is fixedly installed on one side of the primary filter layer 202, the activated carbon adsorption layer 203, and the molecular sieve purification layer 204. During use, the air distribution net 13 can make the incoming exhaust gas evenly distributed, avoiding excessive local airflow that may affect the purification effect. The handles 14 on one side of each filter adsorption layer make it easy for operators to quickly remove and install each layer, improving maintenance convenience and reducing operation time.

[0034] Working Principle: This utility model provides a waste gas adsorption and purification device. The specific usage steps are as follows: When the adsorption and purification component 2 is working, the waste gas enters the treatment chamber 1 through the inlet pipe 208. First, it passes through the oil mist separation net 205 for gas-liquid separation, intercepting oil mist droplets and coarse particles, reducing the load on subsequent filter media. Then, the airflow flows sequentially through the primary filter layer 202, the activated carbon adsorption layer 203, and the molecular sieve purification layer 204, forming a graded and progressive purification path. The primary filter layer 202 traps dust and solid impurities, and the activated carbon adsorbs... Layer 203 removes volatile organic compounds, odors, and some harmful gases; molecular sieve purification layer 204 deeply adsorbs and purifies small molecule pollutants; the flow guide baffle 206, through evenly distributed flow guide holes 207, uniformly distributes and rectifies the airflow, effectively eliminating airflow deviation, short circuits, and eddies, ensuring uniform distribution of waste gas and sufficient contact and reaction with each filter material, extending the effective residence time, and improving adsorption utilization; the clean gas after multi-stage deep purification is stably discharged through the outlet pipe 209, achieving efficient and stable compliant purification treatment of waste gas (e.g., ...). Figure 3 As shown), the airflow control component 3 forms a bidirectional control system through the inlet regulating valve 301 and the outlet regulating valve 303, which adjusts the inlet flow rate of the exhaust gas and the system back pressure in real time to maintain the stability of the airflow field in the treatment chamber 1; the gas flow meter 302 performs real-time online monitoring and quantitative display of the inlet flow rate, providing accurate data support for flow rate adjustment, and facilitating dynamic matching of flow rate according to exhaust gas concentration and treatment load; by accurately controlling the airflow velocity and residence time, it avoids pollutant penetration and incomplete purification due to excessive flow rate, or decreased treatment efficiency and increased equipment operating energy consumption due to excessive flow rate; at the same time, it can adapt to changes in exhaust gas emission under different working conditions, optimize purification reaction conditions, ensure that the adsorption purification component 2 is always in the optimal working range, and improve the overall operational stability and purification reliability of the device (e.g. Figure 4 and Figure 5 (As shown).

[0035] All technical features in this embodiment can be freely combined according to actual needs.
