Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, and in particular to an improved waste gas filtration and purification monitoring device. Background Technology
[0002] Environmental pollution caused by waste gas emissions during industrial production is becoming increasingly serious. Traditional waste gas treatment devices suffer from drawbacks such as insufficient purification efficiency, lack of monitoring methods, and inconvenient equipment maintenance. For example, a single purification process is insufficient to effectively remove multiple pollutants from waste gas, such as organic waste gas, odorous gases, and particulate matter; existing waste gas treatment devices lack real-time monitoring capabilities, making it impossible to promptly understand the composition and concentration of waste gas; spray components mostly use fixed nozzles, resulting in uneven spray coverage and limited dust reduction effects; furthermore, the maintenance of traditional devices requires disassembly of the entire structure, which is cumbersome, time-consuming, and labor-intensive. Therefore, there is an urgent need to develop a waste gas treatment device that integrates multi-stage purification, real-time monitoring, and convenient maintenance to meet the demands of efficient and environmentally friendly industries. Utility Model Content
[0003] To address some of the problems existing in the prior art, this utility model provides an improved waste gas filtration and purification monitoring device. This device significantly improves the purification efficiency and enhances the purification effect of waste gas by combining multiple purification technologies such as UV photo-oxidation catalysis, activated carbon adsorption, and liquid spraying dust suppression. It can be widely applied to various industrial waste gas treatment scenarios and has significant environmental and economic benefits.
[0004] To achieve the above objectives, this utility model provides an improved waste gas filtration, purification, and monitoring device, comprising a device body. The device body includes a UV photocatalytic oxidation waste gas purification treatment box, an activated carbon waste gas purification filter box, and a liquid spray dust suppression purification box arranged sequentially, connected by a gas pipeline to form a channel for waste gas flow. The inlet end of the UV photocatalytic oxidation waste gas purification treatment box is equipped with a detachable filter cotton plate and a gas monitoring component, used for preliminary filtration of waste gas to remove large particulate matter and real-time monitoring of the composition and concentration of waste gas, respectively. The outlet end of the liquid spray dust suppression purification box is equipped with an exhaust pump for discharging the treated gas. A bracket is installed at the lower end of the exhaust pump, which is stably supported on the ground. The liquid spray dust suppression purification box is also equipped with a liquid spray component for spraying and dust suppression treatment of the waste gas.
[0005] In operation, the waste gas first undergoes preliminary filtration through a filter cotton plate at the inlet of the UV photocatalytic oxidation waste gas purification treatment box to remove large particulate matter. Simultaneously, the gas inlet pipe in the gas monitoring component introduces the waste gas, and the gas detector monitors the gas composition and concentration in real time. A heating element connecting block heats the gas to prevent moisture condensation from affecting detection accuracy. Subsequently, the waste gas enters the UV photocatalytic oxidation waste gas purification treatment box, where UV lamps emit specific wavelengths of ultraviolet light, exciting the catalytic network to generate strong oxidizing free radicals, decomposing the organic matter in the waste gas. Then, the waste gas enters the activated carbon waste gas purification filter box through a gas pipeline, where granular activated carbon... A multi-layer activated carbon filter layer, composed of alternating layers of activated carbon and honeycomb activated carbon, adsorbs odors and harmful substances in the exhaust gas. The exhaust gas then enters a liquid spray dust suppression purification chamber. The spray pump of the liquid spray assembly draws in the appropriate liquid from the spray liquid inlet, which is then transported through the spray pipe to a rotating nozzle. The rotating nozzle rotates and sprays the liquid evenly throughout the chamber, suppressing dust from the exhaust gas. A switch control valve controls the liquid flow and the start / stop of the spray. Finally, the cleaned gas is discharged through an exhaust pump. The maintenance door can be opened to allow operators to enter the chamber for maintenance. The observation window is made of transparent material, allowing staff to easily observe the operating status of the equipment inside the chamber.
[0006] The beneficial effects of this utility model are as follows: This utility model utilizes a three-stage series structure consisting of a UV photocatalytic oxidation waste gas purification treatment box, an activated carbon waste gas purification filter box, and a liquid spray dust suppression purification box. Combined with the synergistic effects of UV photocatalytic oxidation decomposition of organic matter, activated carbon adsorption of odors and harmful gases, and liquid spray dust suppression, it significantly improves the comprehensiveness and efficiency of waste gas purification, simultaneously removing organic pollutants, odor substances, and solid particles from the waste gas. The heating element installed within the gas monitoring component preheats the incoming air, effectively preventing moisture condensation and ensuring the gas detector accurately detects the composition of the waste gas. The accuracy of the concentration detection provides a reliable basis for real-time adjustment of purification parameters; the liquid spray assembly adopts a spray pipe structure with rotating nozzles, and the spray pump drives the rotating nozzles to spray at multiple angles, achieving uniform coverage of the spray liquid in the purification chamber, enhancing gas-liquid contact efficiency, and improving dust suppression and purification effects; the inspection door and observation window set on the side wall of the liquid spray dust suppression purification chamber facilitate staff to observe the equipment's operating status and perform internal maintenance, significantly reducing maintenance costs and operational difficulty; the switch control valve set on the spray pipe can flexibly control the liquid flow and realize the adjustment of the spray.
[0007] As a further improvement of this utility model, in order to monitor and accurately detect the composition and concentration of exhaust gas in real time, the gas monitoring component includes a monitoring gas inlet pipe, a gas detector, and a heating element connecting block. The gas detector is used to detect the composition and concentration of the gas entering the UV photocatalytic oxidation exhaust gas purification treatment box, and the heating element connecting block is used to heat the gas entering the monitoring gas inlet pipe to prevent moisture in the gas from condensing and affecting the detection accuracy of the gas detector.
[0008] As a further improvement of this utility model, in order to oxidize and decompose the organic matter in the waste gas and achieve preliminary purification of the waste gas, a UV photocatalytic oxidation module is provided in the UV photocatalytic oxidation waste gas purification treatment box. The UV photocatalytic oxidation module includes a UV lamp and a catalytic mesh. The UV lamp can emit ultraviolet light of a specific wavelength, and the surface of the catalytic mesh is coated with a photocatalytic material layer. The ultraviolet light emitted by the UV lamp excites the catalytic mesh to generate strong oxidizing free radicals, which oxidize and decompose the organic matter in the waste gas.
[0009] As a further improvement of this utility model, in order to increase the contact area between activated carbon and waste gas, improve adsorption efficiency, and achieve efficient adsorption of odors and harmful substances in waste gas, the activated carbon waste gas purification filter box is provided with multiple layers of activated carbon filter layer. The activated carbon filter layer is composed of granular activated carbon and honeycomb activated carbon arranged alternately, which can effectively adsorb odors and harmful substances in waste gas.
[0010] As a further improvement of this utility model, in order to uniformly cover the internal space of the liquid spray dust suppression and purification box with spray liquid, enhance the gas-liquid contact area, and improve the dust suppression and pollutant dissolution effect; at the same time, in order to flexibly control the on / off state and flow rate of spray liquid to adapt to different working conditions and improve operational flexibility, the liquid spray assembly includes a spray pump and a spray pipe. Multiple rotating nozzles are evenly arranged at one end of the spray pipe, and these rotating nozzles are connected to the spray pump through the spray pipe. A spray liquid inlet is provided at the other end of the spray pipe. The spray pump draws liquid from the spray liquid inlet and delivers it to the rotating nozzles through the spray pipe. The rotating nozzles can rotate during spraying, so that the spray liquid uniformly covers the entire internal space of the liquid spray dust suppression and purification box. A switch control valve is also provided on the spray pipe to control the flow and spraying of the liquid.
[0011] As a further improvement of this utility model, in order to view the spraying status inside the box in real time and facilitate operators to enter the interior for inspection and maintenance, thereby reducing maintenance costs and operational difficulties, an inspection door and an observation window are provided on the outer wall of the liquid spraying dust suppression and purification box. The inspection door can be opened and closed, allowing operators to enter the interior for inspection and maintenance. The observation window is made of transparent material, allowing staff to observe the working conditions inside the box at any time. Attached Figure Description
