Description

Technical Field

[0001] This utility model relates to the field of exhaust gas detection technology, and in particular to an exhaust gas emission detection device. Background Technology

[0002] Exhaust gas emissions are a serious source of atmospheric pollution. Industrial enterprises emit various waste gases during combustion and production processes. Therefore, it is necessary to test and analyze the content of harmful substances in the waste gas. When the content of harmful substances in the waste gas is too high, the waste gas needs to be treated until the content of harmful substances meets the emission standards before it can be discharged.

[0003] The prior art CN218956526U discloses an exhaust gas emission detection device, including an exhaust gas analyzer body. A purification component is provided at the bottom of the exhaust gas analyzer body. The purification component includes a shell, an activated carbon mesh, and a hose. By setting the purification component, external gas, after being purified by the activated carbon mesh, can enter the interior of the exhaust gas analyzer body through the hose and the air inlet of the exhaust gas analyzer body. Then, the purified gas can be used to flush the channel through which the exhaust gas flows during the detection process, removing harmful substances remaining in the channel. In this way, the exhaust gas analyzer body will not be affected by the residual exhaust gas in the next detection, thus improving the detection accuracy of the exhaust gas analyzer body.

[0004] However, the purification effect of the above technologies is limited. As the usage time increases, the adsorption capacity of the activated carbon mesh decreases, making it difficult to effectively filter and adsorb impurities and harmful gases in the exhaust gas. This results in some incompletely purified gas entering the exhaust gas analyzer, affecting the detection accuracy, and may even damage the internal components of the instrument. Utility Model Content

[0005] The purpose of this invention is to provide a waste gas emission detection device that solves the problem that the existing technology has limited purification effect, and the activated carbon mesh adsorption capacity decreases with the increase of use time, making it difficult to effectively filter and adsorb impurities and harmful gases in the waste gas, resulting in some incompletely purified gas entering the waste gas analyzer body and affecting the detection accuracy.

[0006] To achieve the above objectives, this utility model provides an exhaust gas emission detection device, including an exhaust gas analyzer body.

[0007] It also includes multi-layer purification components;

[0008] The multi-layer purification assembly includes a purification chamber, a limiting installation component, a primary filter layer, an activated carbon mesh layer, and a photocatalytic electrostatic adsorption component. The purification chamber is fixedly connected to the exhaust gas analyzer body and is located at the bottom of the exhaust gas analyzer body. The limiting installation component is installed on the inner side wall of the purification chamber. The primary filter layer is detachably connected to the purification chamber through the limiting installation component and is located at the lower end of the inner cavity of the purification chamber. The activated carbon mesh layer is detachably connected to the purification chamber through the limiting installation component and is located above the primary filter layer. The photocatalytic electrostatic adsorption component is installed above the activated carbon mesh layer.

[0009] The limiting installation component includes a locking block and a locking screw. The locking block is fixedly connected to the purification chamber and is located on opposite sides of the inner wall of the purification chamber. The locking screw is threadedly connected to the locking block and is located at the front end of the locking block.

[0010] The photocatalytic electrostatic adsorption component includes a mounting frame, an ultraviolet lamp, and an electrostatic adsorption component. The mounting frame is slidably connected to the card block and is located above the activated carbon mesh layer. The ultraviolet lamp is connected to the mounting frame and is located on the inner side wall of the mounting frame. The electrostatic adsorption component is installed on the top of the mounting frame.

[0011] The electrostatic adsorption component includes a connecting frame and an electrode plate. The connecting frame is located above the mounting frame. The electrode plate engages with the connecting frame and is located within a groove in the connecting frame.

[0012] The electrostatic adsorption component further includes inserts, which are fixedly connected to the connecting frame and located at the four opposite corners of the bottom of the connecting frame; the mounting frame has slots, which are located at the top of the mounting frame and correspond to the positions of the multiple inserts.

[0013] This utility model discloses a waste gas emission detection device. During the detection process, the waste gas flows through the pipes of the waste gas analyzer body via the multi-layer purification components. The waste gas enters the inner cavity from the bottom of the purification chamber, and sequentially passes through the primary filter layer to initially intercept particulate impurities. Then, it passes through the activated carbon mesh layer to adsorb harmful gases and organic pollutants. Finally, it passes through the photocatalytic electrostatic adsorption component for further purification and adsorption of fine particles, thus improving the purification level of the waste gas. Furthermore, the limiting installation component facilitates the replacement and installation of each purification component, reducing the amount of impurities and harmful gases entering the waste gas analyzer body and improving detection accuracy.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

Figure 2 This is a schematic diagram of the internal structure of the multi-layer purification component of this utility model. Figure 3 This is an exploded view of the multi-layer purification component of this utility model.

[0021] This utility model discloses a waste gas emission detection device, comprising a waste gas analyzer body 101 and a multi-layer purification assembly. The multi-layer purification assembly includes a purification chamber 102, a limiting installation component, a primary filter layer 103, an activated carbon mesh layer 104, and a photocatalytic electrostatic adsorption component. The limiting installation component includes 105 and a locking screw 106. The photocatalytic electrostatic adsorption component includes a mounting frame 107, an ultraviolet lamp 108, and an electrostatic adsorption component. The electrostatic adsorption component includes a connecting frame 109, an electrode plate 110, and an insert block 111. The mounting frame 107 has a slot 112. This solution addresses the problem of limited purification effect in existing technologies. With prolonged use, the activated carbon mesh's adsorption capacity decreases, making it difficult to effectively filter and adsorb impurities and harmful gases in the waste gas. This results in some incompletely purified gas entering the waste gas analyzer body 101, affecting detection accuracy. It is understood that the aforementioned solution, through the multi-layer purification assembly, is applicable to various waste gas detection equipment, significantly improving waste gas purification effect and ensuring the normal operation and detection accuracy of the detection device.

[0022] In this embodiment, the exhaust gas analyzer body 101 is used to detect the input exhaust gas. The exhaust gas analyzer body 101 is connected to the multi-layer purification component through a pipeline. The purified gas from the multi-layer purification component flushes the pipeline through which the exhaust gas flows during the detection process of the exhaust gas analyzer body 101, thereby avoiding affecting the subsequent detection accuracy of the exhaust gas analyzer body 101 and extending the service life of the exhaust gas analyzer body 101.

[0023] The purification chamber 102 is fixedly connected to the exhaust gas analyzer body 101 and located at the bottom of the exhaust gas analyzer body 101. The limiting installation component is installed on the inner wall of the purification chamber 102. The primary filter layer 103 is detachably connected to the purification chamber 102 through the limiting installation component and is located at the lower end of the inner cavity of the purification chamber 102. The activated carbon mesh layer 104 is detachably connected to the purification chamber 102 through the limiting installation component and is located above the primary filter layer 103. The photocatalytic electrostatic adsorption component is installed above the activated carbon mesh layer 104. The purification chamber 102 has an inner cavity with a bottom opening for gas to enter and be purified. The side openings of the purification chamber 102, from bottom to top, respectively mate with the primary filter layer 103, the activated carbon mesh layer 104, and the photocatalytic electrostatic adsorption component, facilitating the installation and replacement of each purification layer. A pair of limiting installation components are fixedly provided on the inner side of each purification chamber 102 corresponding to the primary filter layer 103, activated carbon mesh layer 104, and photocatalytic electrostatic adsorption component for easy installation and replacement. The primary filter layer 103 is composed of multiple layers of filter cotton with different fiber pore sizes, capable of intercepting particulate impurities of different sizes in the exhaust gas. The limiting installation components are located on the inner wall of the purification chamber 102 at corresponding positions, allowing the primary filter layer 103 to be quickly inserted into the purification chamber 102, facilitating periodic replacement of the filter cotton. The activated carbon mesh layer 104 is made of highly adsorption-performance activated carbon material with a rich pore structure, capable of adsorbing… The photocatalytic electrostatic adsorption component removes harmful gases and organic pollutants from the exhaust gas. The ultraviolet lamp 108, with its adjustable power design, allows for adjustment of light intensity based on the composition and concentration of the exhaust gas, achieving optimal purification. The electrode plate 110 adsorbs charged particles from the exhaust gas, further removing fine particles and pollutants. Therefore, when the purified gas from the multi-layer purification component washes through the pipes through which the exhaust gas analyzer body 101 detects the gas flow, the exhaust gas enters the inner cavity from the bottom of the purification chamber 102. It passes through the primary filter layer 103 for initial interception of particulate impurities, then through the activated carbon mesh layer 104 for adsorption of harmful gases and organic pollutants, and finally through the photocatalytic electrostatic adsorption component for further purification and adsorption of fine particles, improving the purification level of the exhaust gas. Furthermore, the limiting installation component facilitates the replacement and installation of each purification component, reducing the entry of impurities and harmful gases into the exhaust gas analyzer body 101 and improving detection accuracy.

[0024] Secondly, the 105 is fixedly connected to the purification chamber 102 and located on opposite sides of the inner wall of the purification chamber 102; the locking screw 106 is threadedly connected to the 105 and located at the front end of the 105. Three 105s are evenly spaced on both sides of the inner wall of the purification chamber 102, respectively engaging with the grooves on both sides of the frame of the primary filter layer 103, the activated carbon mesh layer 104, and the photocatalytic electrostatic adsorption component, so that each purification component is limited and locked within the purification chamber 102. Each 105 has a threaded groove at its front end, threadedly engaging with the locking screw 106. The locking screw 106 spirals into the latch, securing each purification layer and ensuring its installation is limited. This allows for detachable connection, facilitating subsequent replacement and ensuring good purification effect.

[0025] Meanwhile, the mounting frame 107 is slidably connected to the 105 and is located above the activated carbon mesh layer 104; the ultraviolet lamp 108 is connected to the mounting frame 107 and is located on the inner sidewall of the mounting frame 107; the electrostatic adsorption component is installed on the top of the mounting frame 107. The mounting frame 107 is a rectangular ring, and the left and right sides are provided with sliding grooves that cooperate with the 105. A plurality of ultraviolet lamps 108 are fixedly and evenly arranged around the inner ring of the mounting frame 107, and the surface of the mounting frame 107 is coated with a photocatalytic material. Under the irradiation of the ultraviolet lamps 108, it can generate free radicals with strong oxidizing properties, which decompose harmful gases and organic pollutants in the waste gas into harmless carbon dioxide and water. The ultraviolet lamps 108 adopt an adjustable power design, and the light intensity can be adjusted according to the composition and concentration of the waste gas to achieve the best purification effect. The electrostatic adsorption component is provided on the top of the mounting frame 107 for further removal of small particles and pollutants in the waste gas.

[0026] Then, the connecting frame 109 is located above the mounting frame 107; the electrode plate 110 engages with the connecting frame 109 and is located in the groove of the connecting frame 109; the insert 111 is fixedly connected to the connecting frame 109 and is located at the four opposite corners of the bottom of the connecting frame 109; the slot 112 is provided on the top of the mounting frame 107 and corresponds to the position of the plurality of inserts 111. The connecting frame 109 has the same shape as the mounting frame 107. The connecting frame 109 is inserted into the four slots 112 at the top of the mounting frame 107 via four inserts 111 at the bottom, thereby installing the electrostatic adsorption component on the mounting frame 107. The top left and right sides of the connecting frame 109 are provided with multiple evenly spaced grooves, so that the two ends of the corresponding number of electrode plates 110 are inserted into the grooves at the bottom of the connecting frame 109, thereby installing the electrode plates 110. By applying a high voltage electric field between the multiple parallel electrode plates 110, when the exhaust gas passes through the electrostatic adsorption component, the charged particles in the exhaust gas will be adsorbed by the electrode plates 110, thereby further removing the tiny particles and pollutants in the exhaust gas.

[0027] When using the exhaust gas emission detection device of this utility model, as the purified gas from the multi-layer purification components washes through the pipe through which the exhaust gas flows during the detection process in the exhaust gas analyzer body 101, the exhaust gas enters the inner cavity from the bottom of the purification chamber 102. It then passes through the primary filter layer 103 to initially intercept particulate impurities in the exhaust gas, followed by the adsorption of harmful gases and organic pollutants in the exhaust gas by the activated carbon mesh layer 104, and further purification and adsorption of small particles by the photocatalytic electrostatic adsorption component, thereby improving the purification degree of the exhaust gas. In addition, the limiting installation component facilitates the replacement and installation of each purification component, reduces the entry of impurities and harmful gases into the exhaust gas analyzer body 101, and improves the detection accuracy.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
