Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of waste gas treatment, and more specifically, to an industrial waste gas particulate matter collection device. Background Technology

[0002] In the field of industrial environmental monitoring and pollution control, accurate collection of particulate matter in exhaust gases is a crucial prerequisite for assessing air quality and developing emission reduction plans. However, existing industrial exhaust gas particulate matter collection devices have two significant drawbacks: difficulty in flexibly collecting air samples at different heights and cumbersome operation for changing collection containers, which seriously affect monitoring efficiency and data accuracy. Most current mainstream data collection devices employ a fixed-height sampling structure, requiring manual disassembly and reassembly for adjusting the sampling port position. This makes continuous gradient sampling impossible in scenarios with vertically varying pollutant concentrations, such as workshops and factories, resulting in insufficient data representativeness. More importantly, the collection container and sampling pipeline are often rigidly connected by threads or flanges, requiring equipment shutdown and tool disassembly for replacement. This sampling interruption during the process leads to data loss. This design flaw is particularly prominent in high-frequency, multi-location monitoring tasks: on the one hand, fixed-height sampling may miss high-concentration pollutant layers; on the other hand, frequent shutdowns for container replacement not only reduce daily sampling efficiency but may also lead to sample contamination due to improper operation. For the portable monitoring needs of small and medium-sized enterprises, the bulky structure and complex operation of existing devices are also difficult to adapt. Therefore, developing a collection device with height adjustability and easy, quick container replacement has become an urgent need to improve the efficiency of industrial waste gas monitoring. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide an industrial waste gas particulate matter collection device, which solves the technical problems of inconvenience in collecting air at different heights and inconvenience in changing containers in the prior art.

[0004] According to one aspect, at least one embodiment of this disclosure provides an industrial waste gas particulate matter collection device, comprising: The enclosure and the main pipeline, wherein the main pipeline is fixed to the top of the enclosure; An intake height adjustment assembly is disposed on the main pipe; A data acquisition and filtering component is disposed within the housing; The collection and filtering assembly includes an inner seat, which is disposed inside the box and is horizontally axially installed. A suction fan is installed in the inner seat. A pair of columns are provided on the surface of the inner seat, and a collection shell is fitted onto the columns. The collection shell has an L-shaped pipe structure, and a support layer is provided on the inner wall of the collection shell.

[0005] As a further technical solution, a particulate matter collection net is placed on the support layer, and an electric telescopic rod is vertically downwardly installed on the top of the box. A connecting sleeve is provided at the output end of the electric telescopic rod, and the connecting sleeve is located inside the box.

[0006] As a further technical solution, the connecting sleeve is fitted on the top of the collecting shell, one end of the collecting shell is inserted into the inner seat, and the other end of the inner seat is connected to an inner cylinder by a threaded connection, and a dust filter screen is provided in the inner cylinder.

[0007] As a further technical solution, an adsorption filler is installed on one side of the dust filter, and ventilation nets are fitted at both ends of the inner cylinder, with the dust filter and the adsorption filler located between the dust filter.

[0022] like Figures 1-5 As shown, it illustrates an industrial waste gas particulate matter collection device according to an embodiment of the present disclosure, comprising: The enclosure 1 and the main pipe 2 are fixed to the top of the enclosure 1; An intake height adjustment assembly 4 is disposed on the main pipe 2; A data collection and filtering component 3 is disposed in the housing 1; The collection and filtration assembly 3 includes an inner seat 3-1, which is disposed inside the housing 1 and is horizontally axially mounted. A suction fan 3-2 is installed inside the inner seat 3-1. A pair of uprights 3-3 are provided on the surface of the inner seat 3-1, and a collection shell 3-4 is fitted onto each upright 3-3. The collection shell 3-4 has an L-shaped pipe structure. A support layer 3-5 is provided on the inner wall of the collection shell 3-4, and a particulate matter collection net 3-6 is placed on the support layer 3-5. An electric telescopic rod 3-7 is vertically downwardly mounted on the top of the housing 1. -7 The output end is provided with a connecting sleeve 3-8, which is located inside the housing 1. The connecting sleeve 3-8 is fitted onto the top of the collection shell 3-4. One end of the collection shell 3-4 is inserted into the inner seat 3-1. The other end of the inner seat 3-1 is connected to the inner cylinder 3-9 by a thread. A dust filter 3-10 is provided in the inner cylinder 3-9. An adsorption filler 3-11 is installed on one side of the dust filter 3-10. Ventilation nets 3-12 are fitted onto both ends of the inner cylinder 3-9. The dust filter 3-10 and the adsorption filler 3-11 are located between the dust filter 3-10.

[0023] In some examples, to achieve efficient collection and purification of industrial waste gas particulate matter, a collection and filtration assembly 3 is designed. This assembly includes an inner seat 3-1 fixed horizontally and axially within a housing 1, providing support for each filtration component. A suction fan 3-2 installed in the inner seat 3-1 generates negative pressure when powered on, drawing waste gas into the device. A pair of vertically distributed columns 3-3 on the surface of the inner seat 3-1, with a collection shell 3-4 fitted onto the columns 3-3. The L-shaped pipe structure can change the airflow direction. A horizontally fixed support layer 3-5 on the inner wall is used to place a particulate matter collection net 3-6, which can intercept large particulate impurities in the waste gas. A vertically downward-pointing electric telescopic rod 3-7 at the top of the housing 1 has a connecting sleeve 3-8 at its output end. The connecting sleeve 3-8 fits onto the top of the collection shell 3-4, fixing its position. One end of the collection shell 3-4 is inserted into the inner seat 3-1, ensuring smooth airflow. The inner cylinder 3-9, which is connected to the other end of the inner seat 3-1 by a screw thread, is easy to disassemble and replace. The dust filter 3-10 in the inner cylinder 3-9 can further filter fine particulate matter. The adsorption packing 3-11 (such as activated carbon) on one side can adsorb harmful gases in the exhaust gas. The ventilation nets 3-12 at both ends of the inner cylinder 3-9 prevent the packing from leaking. The dust filter 3-10 and the adsorption packing 3-11 are located between the two ventilation nets 3-12 to form a filtration unit.

[0024] During operation, the suction fan 3-2 draws in exhaust gas, and large particles are trapped by the collection screen as it passes through the collection shell 3-4. The remaining airflow enters the inner cylinder 3-9, where fine particles are filtered by the dust filter 3-10, and then harmful components are purified by the adsorption packing 3-11. The purified air is discharged from the other end of the inner cylinder 3-9, completing the collection and purification process. The cooperation between the electric telescopic rod 3-7 and the connecting sleeve 3-8 facilitates the fixing or disassembly of the collection shell 3-4 and the cleaning of the collection screen. The threaded connection of the inner cylinder 3-9 makes it easy to replace the dust filter 3-10 and the adsorption packing 3-11, resulting in low maintenance costs. The multi-stage filtration structure achieves comprehensive treatment from large particles to harmful gases, improving the purification effect. The negative pressure drive of the suction fan 3-2 ensures that the exhaust gas flows efficiently through each filtration component, guaranteeing collection efficiency. This component, through a combination of layered treatment and convenient maintenance, achieves effective collection and purification of particulate matter in industrial exhaust gas.

[0025] like Figures 1-5 As shown in the figure, the air intake height adjustment component 4 proposed in this embodiment includes a telescopic pipe 4-1, an air collection hood 4-2 is provided at the upper end of the telescopic pipe 4-1, a connecting frame 4-3 is provided on the outer wall of the main pipe 2, a stud 4-4 is provided at the bottom of the air collection hood 4-2, the lower end of the stud 4-4 is fitted into the connecting frame 4-3, and a pair of nuts 4-5 are connected to the lower end of the stud 4-4 by threaded screwing, the nuts 4-5 are located at the upper and lower ends of the connecting frame 4-3.

[0026] In some examples, to achieve flexible adjustment of the gas collection height to adapt to different exhaust gas collection needs under different operating conditions, an intake height adjustment component 4 is designed. This component includes an axially extendable telescopic pipe 4-1 at the upper end of the main pipe 2, and a flared gas collection hood 4-2 at the upper end to increase the exhaust gas collection range. The connecting bracket 4-3 on the outer wall of the main pipe 2 is horizontally fixed, providing a support point for height adjustment. The stud 4-4 at the bottom of the gas collection hood 4-2 is vertically downward, and its lower end is fitted into the connecting bracket 4-3. The threads on the surface of the stud 4-4 cooperate with the nuts 4-5 at the upper and lower ends. By tightening the nuts 4-5, the stud 4-4 can be fixed on the connecting bracket 4-3.

[0027] During operation, when height adjustment is required, loosen the upper and lower nuts 4-5, push the gas collection hood 4-2 to extend or retract the telescopic pipe 4-1, and move the stud 4-4 up and down along the connecting frame 4-3 until the gas collection hood 4-2 reaches the target height; then tighten the upper and lower nuts 4-5 to fix the stud 4-4 to the connecting frame 4-3, keeping the telescopic pipe 4-1 at its current length, and the gas collection hood 4-2 stably collecting exhaust gas at the set height. The axial extension and retraction of the telescopic pipe 4-1 enables continuous adjustment of the gas collection height, adapting to exhaust gas sources of different heights; the flared gas collection hood 4-2 expands the collection range and improves the exhaust gas capture rate; the cooperation between the stud 4-4 and the nut 4-5 ensures precise height locking, preventing displacement due to vibration during use; the supporting role of the connecting frame 4-3 enhances the stability of the adjustment structure, ensuring that the gas collection hood 4-2 can work stably at different heights. This component achieves flexible control of the gas collection height through a simple and reliable mechanical adjustment method, meeting diverse industrial exhaust gas collection needs.

[0028] For example, such as Figure 1 As shown, the gas collection hood 4-2 has a trumpet-shaped structure.

[0029] In some examples, the gas collection hood 4-2 has a funnel-shaped structure, with its larger opening facing the exhaust gas source and its smaller opening connected to the telescopic pipe 4-1. This structure can expand the exhaust gas collection range, increase the amount of exhaust gas drawn in per unit time, and at the same time, utilize the converging effect of the funnel opening to make the exhaust gas enter the telescopic pipe 4-1 more concentratedly, reduce airflow dispersion, enhance the negative pressure utilization rate of the suction fan 3-2, improve the exhaust gas collection efficiency, and better adapt to exhaust gas environments with different diffusion levels.

[0030] For example, such as Figure 3 As shown, both sides of the box 1 are open structures.

[0031] In some examples, the housing 1 has openings on both sides. One opening corresponds to the end of the inner cylinder 3-9, serving as the exhaust port for purified air, while the other opening facilitates the installation and maintenance of the inner seat 3-1 and related components. The openings on both sides form an airflow channel, ensuring the smooth discharge of purified air, preventing excessive air pressure inside the housing 1 from affecting the intake of exhaust gas, and providing convenience for equipment maintenance, thus ensuring the long-term stable operation of the collection and filtration assembly 3.

[0032] In actual use: Loosen the nuts 4-5 on the upper and lower parts of the connecting bracket 4-3, adjust the height of the stud 4-4 so that the gas collection hood 4-2 is at the target collection height, tighten the nuts 4-5 to fix it, and the telescopic pipe 4-1 will extend and retract synchronously with the gas collection hood 4-2. The suction fan 3-2 starts to generate negative pressure, and the industrial waste gas enters the housing 1 through the gas collection hood 4-2, the telescopic pipe 4-1, and the main pipe 2. Large particles are intercepted by the particle collection net 3-6 inside the collection shell 3-4. The remaining airflow enters the inner cylinder 3-9, where the dust filter 3-10 filters fine particles, and the adsorption packing 3-11 purifies harmful gases. The purified gas is discharged from the opening of the housing 1. When the collection net needs to be replaced, the electric telescopic rod 3-7 drives the connecting sleeve 3-8 to rise, and the collection shell 3-4 can be removed for replacement. The inner cylinder 3-9 can be quickly disassembled and installed by screwing on the thread, making it easy to replace the dust filter 3-10 and the adsorption packing 3-11. The entire process realizes waste gas collection at different heights and convenient maintenance.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
