Description

Technical Field

[0001] This utility model relates to the technical field of waste gas purification and treatment devices, and in particular to a multi-flow modular waste gas purification and treatment device. Background Technology

[0002] In chemical, pharmaceutical, and spray painting production processes, large quantities of waste gas containing pollutants such as organic solvents and particulate matter are generated. If not properly treated, this not only poses a serious threat to the health of operators but also has a detrimental impact on the surrounding environment. Therefore, a multi-flow modular waste gas purification and treatment device has emerged. Its core lies in being equipped with a highly efficient waste gas purification and treatment system to achieve compliant emissions of spray painting waste gas, thus promoting the green and environmentally friendly development of spray painting operations.

[0003] In existing technologies, the mechanical structure used for waste gas treatment is typically a single waste gas collection pipe connected to a large centralized treatment unit. The technical principle mainly involves treating waste gas using single methods such as activated carbon adsorption and simple spray scrubbing. After entering the treatment unit through the collection pipe, the waste gas first passes through an activated carbon adsorption layer, where the porous structure of the activated carbon physically adsorbs organic waste gas molecules; or it passes through a spray scrubbing tower, where the waste gas comes into contact with the scrubbing liquid, removing some pollutants through chemical dissolution or physical sedimentation.

[0004] Existing waste gas treatment equipment suffers from poor adaptability to different types and concentrations of waste gas generated during production. Because the composition of waste gas generated at different stages of production is complex and variable, a single treatment method is insufficient to handle this complexity, leading to unstable treatment results and failure to meet environmental protection requirements. This is precisely the problem that this invention aims to solve. Therefore, a multi-flow modular waste gas purification and treatment device is proposed to address the aforementioned issues.

[0027] 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.

[0028] Reference Figures 1-3This utility model provides an embodiment of a multi-flow modular waste gas purification and treatment device, including a housing 1 and a water tank 8. The housing 1 is constructed of high-quality stainless steel, possessing excellent corrosion resistance and sealing properties, effectively preventing waste gas leakage and resisting the corrosion of chemicals generated during the spraying process, thus extending the service life of the equipment. A fixed support 5 is fixedly connected to the outer wall of the housing 1. The fixed support 5 is made of high-strength alloy steel, possessing good load-bearing capacity and corrosion resistance, and can stably support the weight of the entire spray booth, ensuring the equipment remains stable during operation and avoiding the impact of vibration and other factors on the spraying and waste gas treatment effects. An air distribution plate 15 is installed inside the housing 1. The air distribution plate 15 is made of porous metal material with a uniform opening ratio, used for... The exhaust gas entering the chamber 1 is evenly distributed to ensure full contact between the exhaust gas and the biological packing material 17, thereby improving the purification effect. The biological packing material 17 is fixedly connected inside the chamber 1, and is columnar in shape by a porous steel frame. Made of high-quality polypropylene, the biological packing material 17 features a large specific surface area, high porosity, and strong corrosion resistance, providing a favorable growth environment for microorganisms and enabling efficient degradation of harmful substances in the exhaust gas. The biological packing material 17 is columnar in shape by the porous steel frame, and a water distribution device 16 is installed on top of it. Two spray devices 14 are installed inside the chamber 1, with their outer walls positioned on both sides of the biological packing material 17. The spray devices 14 and the water distribution device 16 ensure that the purifying agent is distributed in multiple directions, achieving gas purification. The purification agent can be flexibly adjusted according to the properties of the waste gas, ensuring full contact between the liquid and the purifier. It can be used to purify different waste gases with liquids such as water, acidic liquid, alkaline liquid, or nutrient solution. The purifier is mainly replenished and discharged through a linkage control system using a level gauge or pH meter in the water tank to prevent shortages or overflows that could lead to untimely purification. An observation port 2 is provided inside the housing 1, equipped with highly transparent tempered glass, allowing operators to observe the spraying operation and waste gas treatment status inside the housing 1 in real time, enabling timely detection and handling of problems. An inspection port 3 is provided inside the housing 1, and a collection tank 4 is fixedly connected to the bottom of the housing 1. The collection tank 4 has a conical design, which facilitates the centralized collection and discharge of liquid and sludge, reducing residue. The bottom of the collection tank 4 is open... The tank 1 is equipped with a sludge discharge port 6 and multiple manholes 7 on its top. Each manhole 7 has a sealing cover to ensure airtightness while allowing personnel to easily enter the tank 1 for maintenance and cleaning. A drain pipe 13 and a water inlet pipe 12 are fixedly connected to the outer wall of the tank 8. The water inlet pipe 12 is equipped with a flow meter and a valve to control the water flow and switch. The drain pipe 13, also equipped with a valve and flow meter, facilitates the discharge of liquid from the tank 8. An overflow port 9 is located on the outer wall of the tank 8 to allow excess liquid to drain when the liquid level is too high, preventing overflow. A spray pump 11 and a diffuser pump 10 are fixedly connected to the outer wall of the tank 8.Both the diffuser pump 10 and the spray pump 11 have their inlets located below the liquid level in the water tank 8. An inlet reducer 19 is fixedly connected to the outer wall of the tank body 1, and an inlet pipe 18 is fixedly connected to the outer wall of the inlet reducer 19. An outlet reducer 20 is fixedly connected to the other side of the tank body 1, and an outlet pipe 21 is fixedly connected to the other side of the outlet reducer 20. A water collector 22 is installed on one side of the outlet reducer 20 and is fixedly connected inside the tank body 1. The double-layer water collector 22 of the water collection device can efficiently remove liquid droplets carried in the purified gas, improving the dryness of the gas.

[0029] Working Principle: When the device is working, the exhaust gas generated in the spray booth is first introduced through the air inlet pipe 18. The air inlet reducer 19 adjusts the airflow speed. The air inlet valve, pressure gauge, and pollutant detector on the air inlet pipe 18 monitor the air intake status in real time. The exhaust gas enters the purification module. The air distribution plate 15 in the purification system housing 1 of each module ensures uniform air distribution. Then, the exhaust gas comes into contact with the biological packing material 17. Simultaneously, the spray pump 11 and the water distribution pump 10 draw solution from the water tank 8, spraying and distributing it onto the biological packing material 17 through the spray device 14 and the water distribution device 16, respectively. This ensures the purifying agent is distributed in multiple directions, achieving full gas-liquid contact and multiple reactions to purify the exhaust gas. The purified liquid flows into the collection tank 4 and then back to the water tank 8. The monitoring instruments on 8 monitor the solution status in real time. When the SS concentration exceeds the standard, an alarm will be triggered to clean the sludge at the sludge discharge port 6. In the case of multi-stage module series operation, the overflow ports 9 of adjacent module water tanks 8 are connected, and the height of the overflow ports 9 changes in a gradient to achieve gradient enrichment of the purified liquid. Finally, the purified waste gas passes through the water collector 22 to remove moisture, and then is discharged through the outlet reducer 20 and the outlet pipe 21. The instruments on the outlet pipe 21 can monitor whether the exhaust gas meets the standards. Throughout the process, the modular design allows the device to flexibly combine the number of modules according to the waste gas treatment needs, adapting to waste gas treatment scenarios of different scales and complexities. This solves the problem of the limited application of traditional vertical spray packed towers in special scenarios and improves the flexibility and efficiency of waste gas treatment.
