Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and more specifically to a self-cleaning waste gas aerosol sampling and enrichment device. Background Technology

[0002] A waste gas aerosol sampling and enrichment device is a device used to extract aerosol particles from waste gas, and is commonly used in environmental monitoring, air quality assessment and other fields.

[0003] A search revealed a utility model patent with publication number CN 112255054 B3, which discloses an air aerosol circulating adsorption liquid sampler, belonging to the field of microbial aerosol sampling. The sampler includes a sampling bottle, an air inlet, an air outlet, and a sampling liquid collection port. Air enters the sampling bottle through the air inlet… This device has both high air aerosol adsorption efficiency and maintains a small sampling liquid volume, thereby ensuring high-quality nucleic acid extraction and guaranteeing the activity and culturability of airborne microorganisms for further detection.

[0004] In the aforementioned patent, the ventilation tube needs to be inserted deep into the sampling liquid, so air needs to be pressurized to enter other compartments. When the collected aerosols need to be removed, all the sampling liquid needs to be discharged, which is very troublesome and results in poor aerosol enrichment. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a self-cleaning waste gas aerosol sampling and enrichment device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a self-cleaning waste gas aerosol sampling and enrichment device, including a base, a bracket fixedly connected to the top of the base, a collection component installed inside the bracket, a waste gas input component installed at the bottom inside the collection component, an enrichment component installed at the bottom of the collection component, a sampling liquid driving component installed on the right side of the top of the base, the collection component including an outer shell fixedly connected to the inside of the bracket, a packing frame fixedly connected to the middle inside the outer shell, a liquid pipe fixedly connected to the top inside the outer shell, a spray branch pipe fixedly connected to the outside of the liquid pipe, an atomizing spray nozzle installed at the bottom of the spray branch pipe, an exhaust pipe fixedly connected to the middle of the top of the outer shell, the enrichment component including a threaded frame, a filter membrane fixedly connected to the inside of the threaded frame, the sampling liquid driving component including a liquid frame, a circulating water inlet pipe fixedly connected to the left side of the liquid frame, a circulating liquid pump installed at the bottom of the inner wall of the liquid frame, a circulating water outlet pipe fixedly connected to the bottom of the right side of the liquid frame, and the end of the circulating water outlet pipe away from the liquid frame fixedly connected to the liquid pipe.

[0007] Furthermore, a connecting hole is provided at the bottom of the packing frame, and the inside of the packing frame is filled with plastic corrugated packing.

[0008] Furthermore, the exhaust gas input assembly includes an air inlet pipe fixedly connected to the front of the housing, a vertical pipe fixedly connected to the back of the top of the air inlet pipe, an exhaust gas dispersion head fixedly connected to the top of the vertical pipe, an air blowing hole opened on the outer side of the exhaust gas dispersion head, the exhaust gas dispersion head being located directly below the packing frame, and a liquid drain hole opened on the back of the bottom of the air inlet pipe.

[0009] Furthermore, a tapered frame is fixedly connected to the bottom of the threaded frame, and a connecting pipe is fixedly connected to the bottom of the tapered frame. The bottom of the connecting pipe is fixedly connected to the end of the circulating water inlet pipe away from the liquid frame.

[0010] Furthermore, the bottom of the inner side of the outer shell is provided with an internal thread, and the outer side of the threaded frame is provided with an external thread, and the internal thread and the external thread mesh with each other.

[0011] Furthermore, a positioning ring is fixedly connected to the front of the inner wall of the liquid frame, a buoyancy rod is movably sleeved on the inner side of the positioning ring, a buoyancy frame is fixedly connected to the bottom of the buoyancy rod, a fixing plate is fixedly connected to the top of the buoyancy rod, and a pressure switch is installed on the top of the liquid frame. The pressure switch is electrically connected to the circulating liquid pump.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model includes a collection component and a sampling liquid driving component. The sampling liquid is introduced into the interior of the spray branch pipe and then atomized and sprayed out through the atomizing spray nozzle. The sampling liquid adheres to the surface of the plastic corrugated packing inside the packing frame. As the exhaust gas flows upward and passes through the plastic corrugated packing, the aerosol can fully contact the sampling liquid. Furthermore, after the exhaust gas adsorbed by the packing passes through the packing frame, the atomized sampling liquid sprayed from the atomizing spray nozzle can contact the exhaust gas, further adsorbing and collecting the aerosols that were not adsorbed by the packing, without requiring a large exhaust gas sampling pressure.

[0014] 2. This utility model incorporates an enrichment component, where the collected aerosols fall into the inner side of the filter membrane under gravity along with the sampling liquid for enrichment. The sampling liquid seeps into the interior of the conical frame and enters the interior of the liquid frame through the circulating water inlet pipe for recycling. The enrichment component can be disassembled through the connection of the internal and external threads, making it easy to remove the aerosols collected by the filter membrane without having to drain all the sampling liquid.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The self-cleaning waste gas aerosol sampling and enrichment device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1 to 5This utility model provides a self-cleaning waste gas aerosol sampling and enrichment device, including a base 1, a support 2 fixedly connected to the top of the base 1, a collection component 3 installed inside the support 2, a waste gas input component 4 installed at the bottom inside the collection component 3, an enrichment component 5 installed at the bottom of the collection component 3, and a sampling liquid driving component 6 installed on the right side of the top of the base 1. The collection component 3 includes an outer shell 301 fixedly connected to the inside of the support 2, a packing frame 302 fixedly connected to the middle inside the outer shell 301, a liquid pipe 305 fixedly connected to the top inside the outer shell 301, and a [missing information - likely a component name or component name] fixedly connected to the outside of the liquid pipe 305. The spray branch pipe 306 has an atomizing spray nozzle 307 installed at its bottom. An exhaust pipe 304 is fixedly connected to the middle of the top of the outer casing 301. The enrichment component 5 includes a threaded frame 501, and a filter membrane 504 is fixedly connected to the inner side of the threaded frame 501. The sampling liquid driving component 6 includes a liquid frame 601, a circulating water inlet pipe 602 is fixedly connected to the left side of the liquid frame 601, a circulating liquid pump 604 is installed at the bottom of the inner wall of the liquid frame 601, and a circulating water outlet pipe 603 is fixedly connected to the bottom of the right side of the liquid frame 601. The end of the circulating water outlet pipe 603 away from the liquid frame 601 is fixedly connected to the liquid pipe 305.

[0023] In this embodiment, exhaust gas is introduced into the interior of the outer casing 301 through the inlet pipe 401 and blown out evenly through the blowing hole 404. The liquid frame 601 contains sampling liquid. The outlet of the circulating liquid pump 604 is connected to the circulating water outlet pipe 603, which introduces the sampling liquid into the interior of the spray branch pipe 306. The sampled liquid is then atomized and sprayed out through the atomizing spray nozzle 307. The sampling liquid adheres to the surface of the plastic corrugated packing inside the packing frame 302, thereby causing the exhaust gas to move upward and pass through the plastic corrugated packing. During the process, the aerosol can fully contact the sampling liquid, and after the waste gas adsorbed by the packing material passes through the packing frame 302, the atomized sampling liquid sprayed by the atomizing nozzle 307 can contact the waste gas, further adsorbing and collecting the aerosols that were not adsorbed by the packing material. Finally, the collected aerosols fall into the inner side of the filter membrane 504 with the sampling liquid under gravity for enrichment. The sampling liquid penetrates into the interior of the conical frame 502 and enters the interior of the liquid frame 601 through the circulating water inlet pipe 602 for recycling.

[0024] In a preferred embodiment, the bottom of the packing frame 302 is provided with a connecting hole 303, and the inside of the packing frame 302 is filled with plastic corrugated packing.

[0025] The exhaust gas flows upward through the connecting hole 303, and the sampling liquid on the corrugated plastic surface can fully contact the exhaust gas, thereby adsorbing and collecting aerosols.

[0026] In a preferred embodiment, the exhaust gas input assembly 4 includes an air inlet pipe 401 fixedly connected to the front of the housing 301, a vertical pipe 402 fixedly connected to the back of the top of the air inlet pipe 401, an exhaust gas dispersion head 403 fixedly connected to the top of the vertical pipe 402, an air blowing hole 404 opened on the outer side of the exhaust gas dispersion head 403, the exhaust gas dispersion head 403 is located directly below the packing frame 302, and a drain hole 405 is opened on the back of the bottom of the air inlet pipe 401.

[0027] Exhaust gas is introduced into the interior of the outer casing 301 through the air inlet pipe 401 and blown out evenly through the air blowing hole 404. The sampling liquid that enters the interior of the exhaust gas dispersion head 403 through the air blowing hole 404 is discharged through the drain hole 405.

[0028] In a preferred embodiment, a tapered frame 502 is fixedly connected to the bottom of the threaded frame 501, and a connecting pipe 503 is fixedly connected to the bottom of the tapered frame 502. The bottom of the connecting pipe 503 is fixedly connected to the end of the circulating water inlet pipe 602 away from the liquid frame 601.

[0029] The sampling liquid can permeate from the top surface of the filter membrane 504 to the bottom of the filter membrane 504, while the aerosol remains on the surface of the filter membrane 504 and accumulates.

[0030] In a preferred embodiment, the bottom of the inner side of the outer casing 301 is provided with an internal thread 311, and the outer side of the threaded frame 501 is provided with an external thread, and the internal thread 311 and the external thread mesh with each other.

[0031] The enrichment component 5 can be disassembled through the connection between the internal thread 311 and the external thread, thereby facilitating the removal of the aerosol collected by the filter membrane 504.

[0032] In a preferred embodiment, a positioning ring 605 is fixedly connected to the front of the inner wall of the liquid frame 601, a buoyancy rod 606 is movably sleeved on the inner side of the positioning ring 605, a buoyancy frame 607 is fixedly connected to the bottom of the buoyancy rod 606, a fixing plate 608 is fixedly connected to the top of the buoyancy rod 606, and a pressure switch 609 is installed on the top of the liquid frame 601. The pressure switch 609 is electrically connected to the circulating liquid pump 604.

[0033] Because the sampling liquid permeates slowly through the filter membrane 504, it cannot flow back into the liquid frame 601 in time. When the sampling liquid level inside the liquid frame 601 drops, the buoyancy frame 607, buoyancy rod 606, and fixed plate 608 decrease in height as the liquid level decreases. When the fixed plate 608 contacts the pressure switch 609, the pressure switch 609 transmits a signal to the circulating liquid pump 604, and the circulating liquid pump 604 stops working.

[0034] The working principle of this utility model is as follows: Exhaust gas is introduced into the interior of the outer casing 301 through the inlet pipe 401 and blown out evenly through the blowing hole 404. The liquid frame 601 contains sampling liquid. The outlet of the circulating liquid pump 604 is connected to the circulating water outlet pipe 603, which introduces the sampling liquid into the interior of the spray branch pipe 306. Then, it is atomized and sprayed out through the atomizing spray nozzle 307. The sampling liquid adheres to the surface of the plastic corrugated packing inside the packing frame 302, thereby causing the exhaust gas to move upward and pass through the plastic corrugated packing. During the sampling process, the aerosol can fully contact the sampling liquid. After the waste gas adsorbed by the packing material passes through the packing frame 302, the atomized sampling liquid sprayed by the atomizing nozzle 307 can contact the waste gas, further adsorbing and collecting the aerosols that were not adsorbed by the packing material. Finally, the collected aerosols fall into the inner side of the filter membrane 504 with the sampling liquid under gravity for enrichment. The sampling liquid penetrates into the interior of the conical frame 502 and enters the interior of the liquid frame 601 through the circulating water inlet pipe 602 for recycling.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
