Description

Technical Field

[0001] This utility model relates to the technical field of waste gas purification devices, and in particular to an environmentally friendly pipeline-type waste gas adsorption and purification device. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life. These waste gases mainly originate from industrial facilities such as chemical plants, steel plants, pharmaceutical plants, coking plants, and oil refineries. The waste gases emitted by these plants have strong odors, seriously pollute the environment, and affect human health. The composition of waste gases is very complex and may contain a variety of toxic and harmful substances, such as ammonia, hydrogen sulfide, trimethylamine, styrene, organic solvents, sulfur dioxide, and nitric oxide.

[0003] Adsorption is a method that uses adsorption properties to adsorb harmful substances in waste gas onto a solid surface, thereby purifying the waste gas. Commonly used adsorbents include activated carbon and molecular sieves. When filter plates are installed in pipelines to adsorb and filter impurities in waste gas, the filter plates will become clogged after long-term use. Even if the filter plates are cleaned with scrapers, the adsorbed substances scraped off from the filter plates will remain in the pipeline, and these adsorbed substances will flow again with the waste gas, which can easily cause secondary pollution of the waste gas. Therefore, an environmentally friendly pipeline waste gas adsorption and purification device is proposed. Utility Model Content

[0026] Example

[0027] Reference Figures 1-4 This is an embodiment of the present invention, which provides an environmentally friendly pipeline-type waste gas adsorption and purification device, including: an adsorption unit 100 and a cleaning unit 200;

[0028] The adsorption unit 100 includes a U-shaped tube 101, with an air inlet pipe 102 and an exhaust pipe 103 fixedly connected to the two ends of the top of the U-shaped tube 101, and multiple equally spaced filter plates 104 fixedly connected to the inner wall of the U-shaped tube 101.

[0029] The cleaning unit 200 includes multiple nozzles 201 fixedly connected to the inner wall of the U-shaped tube 101. Each filter plate 104 is located between two adjacent nozzles 201. The upper end of each nozzle 201 passes through the U-shaped tube 101. The upper ends of the multiple nozzles 201 are fixedly connected to a T-shaped tube 202. The two ends of the T-shaped tube 202 are sealed laterally. The bottom of the wall of the U-shaped tube 101 is fixedly connected to multiple drain pipes 203. Each filter plate 104 is located between two adjacent straight pipes 204. The bottom ends of the multiple drain pipes 203 are fixedly connected to a straight pipe 204. The walls of the T-shaped tube 202 and the straight pipe 204 are fitted with electrically controlled valves.

[0030] Exhaust gas enters the U-shaped pipe 101 through the inlet pipe 102. The exhaust gas in the U-shaped pipe 101 passes through each filter plate 104 in sequence. The filter plate 104 can filter the exhaust gas, causing impurities to adhere to the filter plate 104. The top of the T-shaped pipe 202 can be connected to an external water pump. By opening the electric control valve of the T-shaped pipe 202, clean water can be delivered to each nozzle 201 through the T-shaped pipe 202. The clean water can be mixed with the corresponding agent to purify the exhaust gas. The multiple nozzles 201 can rinse both sides of the filter plate 104 to ensure that the filter plate 104 does not become blocked. The exhaust gas will come into contact with the water, causing some impurities to adhere to the water, thus purifying the exhaust gas. The purified exhaust gas is discharged through the exhaust pipe 103.

[0031] Water and impurities can be stored in the U-shaped tube 101 to prevent impurities and clean water from flowing into the exhaust pipe 103 with the exhaust gas, thus preventing secondary pollution of the purified exhaust gas. The wastewater generated during cleaning will automatically flow into the drain pipe 203. The end of the straight pipe 204 near the air inlet pipe 102 is sealed. By opening the electric control valve of the straight pipe 204, the wastewater and impurities can be discharged from the straight pipe 204.

[0032] In addition, a T-shaped rod 205 is rotatably connected to one side of one of the filter plates 104. One end of the T-shaped rod 205 passes through the filter plate 104 and is fixedly connected to a fan blade 206. A scraper 207 is fixedly connected to the side wall of the T-shaped rod 205. A water spray pipe 208 is fixedly connected to the wall of the T-shaped pipe 202. One end of the water spray pipe 208 passes through the U-shaped pipe 101.

[0033] The filter plate 104, located near the intake pipe 102, is the first to come into contact with the exhaust gas. A large amount of impurities will adhere to one side of the filter plate 104. A fan blade 206 is provided on one side of the filter plate 104. The bottom end of the water spray pipe 208 is aligned with the blade of the fan blade 206. The water spray pipe 208 can spray a high-pressure water jet onto the blade, causing the fan blade 206 to rotate under water pressure. The fan blade 206 drives the scraper 207 to rotate through the T-bar 205, so that the scraper 207 can scrape off the impurities attached to the filter plate 104.

[0034] Furthermore, the inner wall of the U-shaped pipe 101 is fixedly connected with a plurality of U-shaped pieces 209 corresponding to the position of the drain pipe 203. Each U-shaped piece 209 is fixedly connected with a circular piece 210 at its top. The wall of the U-shaped pipe 101 is fixedly connected with a transparent pipe 211, which is L-shaped and bent.

[0035] The water level in the U-shaped tube 101 is higher than the height of the straight tube 204 but lower than the height of the disc 210, to ensure that gas does not enter the straight tube 204. The U-shaped disc 209 is located at the opening at the top of the drain pipe 203. Both the U-shaped disc 209 and the disc 210 are used to block the exhaust gas flowing in the U-shaped tube 101 to prevent the exhaust gas from blowing the water surface and causing some gas to enter the straight tube 204. The connection end of the transparent tube 211 to the U-shaped tube 101 is close to the bottom of the U-shaped tube 101. Some water in the U-shaped tube 101 will flow into the transparent tube 211. The water level in the U-shaped tube 101 can be observed through the transparent tube 211 to avoid excessive water affecting the flow of exhaust gas.

[0036] Furthermore, the inner wall of the exhaust pipe 103 is fixedly connected to multiple inclined baffles 105, with gaps between the baffles 105 and staggered distribution. The inner wall of the exhaust pipe 103 is also fixedly connected to multiple equidistant activated carbon plates 106, all of which are located above the baffles 105.

[0037] When the exhaust gas enters the exhaust pipe 103 and flows upward, it passes through each baffle 105 in sequence. The moisture contained in the exhaust gas is intercepted by the baffle 105, and the water condensed on the baffle 105 drips into the U-shaped pipe 101 to reduce moisture loss. The activated carbon plate 106 can further purify the exhaust gas and reduce the irritating odor in the exhaust gas.

[0038] During use, exhaust gas enters the U-shaped tube 101 through the intake pipe 102. The filter plate 104 filters the exhaust gas, causing impurities to adhere to the filter plate 104. The top of the T-shaped tube 202 is connected to a water pump and the electric control valve of the T-shaped tube 202 is opened. The nozzle 201 is used to rinse both sides of the filter plate 104. High-pressure water jets are sprayed onto the blades through the water spray pipe 208, causing the fan blades 206 to rotate under water pressure. The fan blades 206 drive the scraper 207 to rotate through the T-shaped rod 205, so that the scraper 207 can scrape off the impurities attached to the filter plate 104. The water level in the U-shaped tube 101 can be observed through the transparent tube 211 to ensure that the water level in the U-shaped tube 101 is higher than the height of the straight pipe 204 and lower than the height of the circular plate 210.

[0039] The wastewater generated during cleaning will automatically flow into the drain pipe 203. By opening the electric control valve of the straight pipe 204, the wastewater and impurities can be discharged from the straight pipe 204. The baffle 105 can intercept the moisture contained in the exhaust gas, and the activated carbon plate 106 can further purify the exhaust gas and reduce the irritating odor in the exhaust gas.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
