Technical Field
[0001] This utility model relates to the field of chemical catalytic organic waste gas treatment, and in particular to a chemical catalytic organic waste gas treatment device. Background Technology
[0002] Volatile organic waste gas refers to volatile organic compounds with a boiling point of 50-260℃ at normal pressure and a saturated vapor pressure greater than 133.32Pa at room temperature. Its main components are hydrocarbons, sulfides, ammonia, etc. It reacts with nitrogen dioxide in the atmosphere to produce ozone, which can form photochemical smog and is emitted into the air along with odors and foul smells. After being absorbed by the human body, it can greatly harm people's physical and mental health and has a detrimental effect on the living environment and the growth of animals and plants. At present, organic waste gas is usually purified by organic waste gas treatment devices.
[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Existing organic waste gas treatment devices generally adopt a single filtration stage design, which can only capture larger particles through simple physical barrier effects, resulting in low filtration efficiency. Utility Model Content
[0004] In order to improve the problem that existing organic waste gas treatment devices generally adopt a single filtration stage design, which can only capture larger particles through simple physical barrier and has low filtration efficiency, this application provides a chemical catalytic organic waste gas treatment device.
[0005] This application provides a chemical catalytic organic waste gas treatment device with the following technical solution: The chemical catalytic organic waste gas treatment device includes a filter assembly and a disassembly assembly. The disassembly assembly is installed on the filter assembly. The filter assembly includes a filter tank, with an L-shaped tube fixed to its side surface. A support column is fixed to the bottom surface of the filter tank, and a concave ring is fixed to the top surface of the filter tank. A connecting cover is provided on the top surface of the filter tank, and multiple sets of filter screens are fixed to the inner wall of the connecting cover. A purification tank is provided on the top surface of the connecting cover, with a U-shaped sleeve fixed to its inner wall and a trapezoidal block fixed to its inner wall. A connecting frame is provided on the inner wall of the purification tank, and a trapezoidal groove is opened on the surface of the connecting frame. A limit bolt is threadedly connected to the surface of the purification tank. A UV lamp is fixed to the top surface of the purification tank, and a quartz lens sleeve is fitted onto the surface of the UV lamp. An exhaust pipe is fixed to the top surface of the purification tank, and an electrically controlled valve is provided on the surface of the exhaust pipe. A filter plate is provided inside the connecting frame.
[0006] By adopting the above technical solution, external exhaust gas flows into the filter tank through the external channel of L-pipe. Simultaneously, a quantitative amount of filtrate is injected into the filter tank through the feed pipe and the electric control valve. The exhaust gas fully contacts the filtrate in the filter tank to complete the initial impurity interception. Then, it flows in a spiral upward path through multiple sets of filter screens inside the connecting cover. After intercepting large particles, it enters the purification tank. At this time, the UV lamp is activated to perform photocatalytic degradation on the exhaust gas after secondary filtration by the filter plate inside the connecting frame. The ozone feedback controller on the surface of the purification tank monitors in real time and dynamically adjusts the power of the UV lamp.
[0007] In a further configuration, a servo motor is fixed to the bottom surface of the filter tank, and a stirring block is fixed to the extended shaft of the servo motor. A telescopic rod is fixed to the surface of the stirring block, and a spring is sleeved on the surface of the telescopic rod. A scraper is also fixed to the surface of the telescopic rod.
[0008] By adopting the above technical solution, the stirring block is driven to rotate by a servo motor, which in turn drives the telescopic rod and scraper to rotate, thus cleaning the inside of the filter tank.
[0009] Further, the disassembly assembly includes a sleeve fixed to the surface of the connecting cover. The surface of the sleeve is provided with a sliding groove. A protrusion is movably connected inside the sleeve, and a sliding post is fixed to the surface of the protrusion. A guide sleeve is fixed to both the surface of the protrusion and the inner wall of the sleeve, and a spring is sleeved on the surface of the guide sleeve.
[0010] By adopting the above technical solution, if it is necessary to clean the filter tank, the sliding column can be used to drive the convex column to move axially and disengage from the concave ring limit. Then, the connecting cover can be slidably separated along the guide groove to complete the opening of the internal maintenance channel.
[0011] Furthermore, the first protrusion passes through the connecting cover and the concave ring in sequence, and extends into the interior of the concave ring.
[0012] Further, a sleeve two is fixed to the surface of the purification tank, and a sliding groove two is opened on the surface of the sleeve two. A protruding post two is movably connected inside the sleeve two, and a sliding post two is fixed to the surface of the protruding post two. A guide sleeve two is fixed to both the surface of the protruding post two and the inner wall of the sleeve two, and a spring three is sleeved on the surface of the guide sleeve two. An ozone feedback controller is fixedly installed on the surface of the purification tank.
[0013] Further, a drain pipe is fixed to the surface of the purification tank, and an electrically controlled valve 2 is provided on the surface of the drain pipe. A feed pipe is fixed to the side surface of the purification tank, and an electrically controlled valve 3 is provided on the surface of the feed pipe. A magnet array is fixed to the surface of the feed pipe.
[0014] Furthermore, the bottom surface of the connecting cover is in contact with the top surface of the filter tank, and multiple sets of support columns are provided, with the support columns arranged symmetrically to each other.
[0015] Compared with related technologies, the chemical catalytic organic waste gas treatment device provided by this utility model has the following beneficial effects:
[0016] This utility model provides a chemical catalytic organic waste gas treatment device. It uses an external L-tube to force-feed waste gas through a filter tank, combined with a feed pipe and an electrically controlled valve for precise injection of filtrate, forming a gas-liquid contact primary filtration system. This system can directly intercept suspended particles and some gaseous pollutants in the flue gas. Multiple sets of filters inside the connecting cover form a physical barrier, achieving tiered interception of large particles through a pore size gradient distribution. This, combined with a filter plate inside the purification tank, performs secondary deep filtration. This combined filtration structure effectively extends the pollutant retention time and improves the purification efficiency per unit volume. The purification tank integrates a closed-loop control system consisting of a UV lamp and an ozone feedback controller. By dynamically adjusting the UV lamp power based on real-time ozone concentration monitoring, it ensures the energy supply required for the photocatalytic reaction while preventing excessive ozone escape.
[0017] This utility model provides a chemical catalytic organic waste gas treatment device. Through the sliding separation mechanism composed of the second sliding column and the second convex column, the purification tank can be quickly disassembled as a whole. Combined with the axial unlocking mechanism of the first sliding column and the concave ring, the internal cleaning and maintenance of the filter tank is convenient, which indirectly ensures long-term operational stability.

[0023] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model.
[0024] Example 1:
[0025] like Figure 1-4 As shown, the chemical catalytic organic waste gas treatment device of this utility model includes a filter assembly 1 and a disassembly assembly 2.

An exhaust pipe 115 is fixed to the top surface of the purification tank 107, and an electric control valve 116 is provided on the surface of the exhaust pipe 115. A filter plate 134 is provided inside the connecting frame 110.
[0026] like Figure 1-4As shown, external exhaust gas flows into the filter tank 101 through the external channel of L pipe 102. Simultaneously, a quantitative amount of filtrate is injected into the filter tank 101 through the feed pipe 128 and the electronic control valve 129. The exhaust gas fully contacts the filtrate in the filter tank 101 to complete the initial impurity interception. Then, it flows in a spiral upward path through multiple sets of filter screens 106 inside the connecting cover 105. After intercepting large particles, it enters the purification tank 107. At this time, the UV lamp tube 113 is activated to perform photocatalytic degradation on the exhaust gas after secondary filtration through the filter plate 134 inside the connecting frame 110. The ozone feedback controller 133 on the surface of the purification tank 107 monitors and dynamically adjusts the UV lamp power in real time.
[0027] like Figure 1-4 As shown, a servo motor 117 is fixed to the bottom surface of the filter tank 101, and a stirring block 118 is fixed to the extension shaft of the servo motor 117. A telescopic rod 119 is fixed to the surface of the stirring block 118, and a spring 132 is sleeved on the surface of the telescopic rod 119. A scraper 120 is fixed to the surface of the telescopic rod 119.
[0028] like Figure 1-4 As shown, the servo motor 117 drives the stirring block 118 to rotate, which in turn drives the telescopic rod 119 and the scraper 120 to rotate, thus cleaning the inside of the filter tank 101.
[0029] like Figure 1-4 As shown, a sleeve 121 is fixed to the surface of the purification tank 107, and a sliding groove 122 is provided on the surface of the sleeve 121. A protrusion 123 is movably connected inside the sleeve 121, and a sliding post 124 is fixed to the surface of the protrusion 123. A guide sleeve 131 is fixed to both the surface of the protrusion 123 and the inner wall of the sleeve 121, and a spring 125 is sleeved on the surface of the guide sleeve 131. An ozone feedback controller 133 is fixedly installed on the surface of the purification tank 107.
[0030] like Figure 1-4 As shown, a drain pipe 126 is fixed on the surface of the filter tank 101, and an electric control valve 127 is provided on the surface of the drain pipe 126.

[0032] In practice, exhaust gas is first introduced into the filter tank 101 via the external L-pipe 102. Simultaneously, filtrate is injected into the filter tank 101 via the feed pipe 128 and the electronically controlled valve 129. The exhaust gas undergoes preliminary filtration by the filtrate inside the filter tank 101. The filtered exhaust gas then passes through multiple sets of filter screens 106 inside the connecting cover 105 to intercept large particles. Subsequently, the gas enters the purification tank 107. A filter plate 134 is installed inside the connecting frame 110 to filter the exhaust gas again. At the same time, the UV lamp tube 113 is activated to perform photocatalysis on the exhaust gas. Meanwhile, an ozone feedback controller 133 is installed on the surface of the purification tank 107 to detect the ozone concentration and automatically adjust the UV lamp power to prevent excessive generation. By sliding the sliding column 124, the sliding column 124 can drive the convex column 123 to slide, thereby separating the convex column 123 from the connecting frame 110. By sliding the purification tank 107, the purification tank 107 can be disassembled.
[0033] Example 2:
[0034] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: the disassembly assembly 2 includes a sleeve 201 fixed to the surface of the connecting cover 105. The surface of the sleeve 201 is provided with a sliding groove 202. The inside of the sleeve 201 is movably connected with a protrusion 203, and a sliding post 204 is fixed to the surface of the protrusion 203. A guide sleeve 205 is fixed to both the surface of the protrusion 203 and the inner wall of the sleeve 201, and a spring 206 is sleeved on the surface of the guide sleeve 205.
[0035] like Figure 1-4 As shown, if the filter tank 101 needs to be cleaned, the sliding column 204 drives the protruding column 203 to move axially and disengage from the concave ring 104 limit. Then, the connecting cover 105 can be slidably separated along the guide groove to complete the opening of the internal maintenance channel.
[0036] like Figure 1-4 As shown, the protruding post 203 passes through the connecting cover 105 and the concave ring 104 in sequence, and extends into the interior of the concave ring 104.
[0037] During implementation, when it is necessary to disassemble the connecting cover 105, the sliding column 204 can be slid to drive the protruding column 203 to slide, thereby separating the protruding column 203 from the concave ring 104. At the same time, the connecting cover 105 can be disassembled by sliding, which facilitates cleaning of the inside of the filter tank 101.
[0038] The advantages of this technical solution in practical applications include, but are not limited to, the following:
[0039] 1. The combined filtration architecture of filter canister 101 + multi-stage filter screen 106 + filter plate 134 achieves graded purification of flue gas in enclosed spaces.
[0040] 2. An adaptive purification system is constructed by using UV lamp tube 113 for photocatalysis and ozone feedback controller 133 for dynamic adjustment, and is equipped with a quick-release maintenance structure.
[0041] In this technical solution, exhaust gas is first introduced into the filter tank 101 via an external L-pipe 102. Simultaneously, filtrate is injected into the filter tank 101 via the feed pipe 128 and the electronically controlled valve 129. The exhaust gas undergoes preliminary filtration by the filtrate inside the filter tank 101. The filtered exhaust gas then passes through multiple sets of filter screens 106 inside the connecting cover 105 to intercept large particles. The gas then enters the purification tank 107, where a filter plate 134 is installed inside the connecting frame 110 for further filtration. Simultaneously, UV lamps 113 are activated to photocatalyze the exhaust gas. The surface of the purification tank 107 is also equipped with… An ozone feedback controller 133 is provided to detect the ozone concentration and automatically adjust the UV lamp power to avoid excessive generation. By sliding the second sliding column 124, the second sliding column 124 can drive the second protruding column 123 to slide, thereby separating the second protruding column 123 from the connecting frame 110. The purification tank 107 can be removed by sliding it. When it is necessary to remove the connecting cover 105, the first sliding column 204 can drive the first protruding column 203 to slide, thereby separating the first protruding column 203 from the concave ring 104. At the same time, the connecting cover 105 can be removed by sliding it, which facilitates the cleaning of the inside of the filter tank 101.
