Description

Technical Field

[0001] This invention relates to the field of air purification technology, and in particular to a circulating dust removal, humidification, and rinsing device. Background Technology

[0002] In existing air handling equipment, humidifiers and filters typically operate independently. Standalone wet-film humidifiers may produce "white powder" pollution and do not have dust removal capabilities; while traditional dry dust filters (such as screen filters) require regular replacement, resulting in high maintenance costs and the inability to regulate air humidity.

[0003] There are some devices on the market that combine water washing and dust removal, but their water circulation systems are usually quite simple. The water used for spraying is directly pumped back for circulation, and the dust and impurities accumulated in the water can easily clog the spray nozzles, leading to decreased efficiency, increased noise, and even the need for frequent water changes. These devices fail to fundamentally solve the problems of effective water resource utilization and long-term stable system operation. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a circulating dust removal, humidification, and rinsing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a circulating dust removal and humidification flushing device, comprising a housing, a spray unit disposed at the front of the housing, a humidification and dust removal filter located behind the spray unit, and a water tank and a circulating water pump located at the bottom of the housing. The front wall and rear wall of the housing are respectively provided with an air inlet and an air outlet. The spray unit and the humidification and dust removal filter are both disposed above the water tank. The spray unit includes at least one horizontally arranged spray pipe with a plurality of spray micro-holes. The top of the humidification and dust removal filter is provided with a water distribution pipe with a plurality of spray micro-holes. The top of the water tank is provided with a water filter located below the humidification and dust removal filter. The circulating water pump is disposed inside the water tank. The inlet of the circulating water pump is located at the bottom of the water tank, and the outlet is connected to the spray pipe and the water distribution pipe through a pipeline.

[0006] Preferably, the spray micro-holes of the spray pipe are located near the humidifying and dust-removing filter screen, and the spray micro-holes of the water distribution pipe are located at the top of the water distribution pipe, with the aperture of the spray micro-holes being 0.1mm-0.5mm.

[0007] Preferably, the filter material of the humidifying dust removal filter is vertically folded, and the fold angle of the vertical folds of the humidifying dust removal filter ranges from 0.5° to 30°.

[0008] Preferably, the top of the water tank is provided with a support plate, the left and right ends of the support plate are connected and fixed to the inner wall of the shell, the front and rear of the top of the support plate are fixed with baffles, the bottom of the support plate is provided with at least one support block, the middle of the support plate is provided with at least one through hole, the bottom of the support plate is provided with a downward recessed groove, the bottom surface of the groove is mesh, the water filter screen is placed flat in the groove, the humidifying and dust-removing filter screen is placed on the support plate, and the humidifying and dust-removing filter screen is fixed to the shell with screws.

[0009] Preferably, both the air inlet and the air outlet are located above the water tank.

[0010] Preferably, the side wall of the water tank is provided with an outlet pipe and an inlet pipe. The outlet pipe is connected to the water tank and is close to the bottom surface of the water tank. The inlet pipe is connected to the water tank and is located above the outlet pipe and does not exceed the top of the water tank. An automatic water replenishment valve is provided at the end of the inlet pipe located inside the water tank.

[0011] Preferably, the side wall of the water tank is provided with a fixing plate, the bottom surface of the fixing plate is fixed with a water level sensor, the water level sensor extends into the water tank, and the bottom of the water level sensor is lower than the bottom of the water inlet pipe and higher than the water inlet of the circulating water pump.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention organically integrates dust removal, humidification, self-cleaning, and water quality maintenance into a closed-loop system, and introduces a collaborative working mechanism. Through secondary humidification and dust removal via spraying and a filter screen, and rinsing the filter media via a top water distribution pipe, the interaction path, timing, and functional allocation of air and water in the entire system are changed. A water filter screen is installed at the top of the water tank, located below the humidification and dust removal filter screen. Water dripping from the humidification and dust removal filter screen must pass through the water filter screen before entering the water tank, preventing dust and impurities accumulated in the water from clogging the spray micropores, thus avoiding decreased efficiency, increased noise, and reduced water change frequency. This fundamentally solves the problems of effective water resource utilization and long-term stable system operation. Because the dust adhering to the filter media surface is absorbed by a large amount of water vapor... To prevent scaling, a water distribution pipe is installed at the top of the humidifying dust removal filter. Water sprayed from the water distribution pipe at the top of the filter media falls along the filter media, carrying away dirt from the surface and keeping the filter media clean. A support plate is installed at the top of the water tank. Below the through holes of the support plate, there is a downward-recessed groove. The water filter is placed flat in the groove, and the humidifying dust removal filter is placed on the support plate for easy disassembly, cleaning, or replacement. The filter material of the humidifying dust removal filter has a vertical fold design. When the water mist carrying dust and air pass through, the remaining dust collides with and is adsorbed by the moist filter material and is trapped. At the same time, the water that is not carried away by the air and remains on the filter material evaporates naturally under the action of airflow, realizing secondary humidification of the air and making the humidity output more uniform and natural. When the water distribution pipe sprays, the excess water can flow down along the fold. Attached Figure Description

Detailed Implementation

[0021] To provide a further understanding of the purpose, structure, features, and functions of the present invention, detailed descriptions are provided below with reference to specific embodiments.

[0022] Please refer to the reference. Figures 1-7This invention provides a circulating dust removal and humidification flushing device, including a housing 1, a spray unit 2 disposed at the front of the housing 1, a humidifying dust removal filter 3 disposed behind the spray unit 2, and a water tank 4 and a circulating water pump 6 disposed at the bottom of the housing 1. The front wall and rear wall of the housing 1 are respectively provided with an air inlet 18 and an air outlet 19. The spray unit 2 and the humidifying dust removal filter 3 are both disposed above the water tank 4. The spray unit 2 includes at least one horizontally arranged spray pipe 21, and the spray pipe 21 is provided with a plurality of spray micro-holes 22. The top of the humidifying dust removal filter 3 is provided with a water distribution pipe 7, and the water distribution pipe 7 is provided with a plurality of spray micro-holes 22. The top of the water tank 4 is provided with a water filter 5, and the water filter 5 is located below the humidifying dust removal filter 3. The circulating water pump 6 is disposed in the water tank 4. The water inlet of the circulating water pump 6 is located at the bottom of the water tank 4, and the water outlet is connected to the spray pipe 21 and the water distribution pipe 7 through a pipeline.

[0023] A water filter screen 5 is installed at the top of the water tank 4, and the water filter screen 5 is located below the humidifying and dust-removing filter screen 3. The water dripping from the humidifying and dust-removing filter screen 3 must pass through the water filter screen 5 before entering the water tank. This prevents dust and impurities accumulated in the water from clogging the spray micropores, which would lead to decreased efficiency, increased noise, and reduced water change frequency. This fundamentally solves the problems of effective water resource utilization and long-term stable system operation. Since dust adhering to the filter media surface is prone to scaling due to a large amount of water vapor, a water distribution pipe 7 is installed at the top of the humidifying and dust-removing filter screen 3. The water sprayed from the water distribution pipe 7 at the top of the filter media... Water falls along the filter material, carrying away dirt from the surface of the filter material and cleaning the surface of the filter material; the spray unit 2 includes at least one horizontally arranged spray pipe 21 to ensure that the water mist sprayed by the spray unit 2 can fully cover the humidifying and dust-removing filter screen 3; the filter screen of the humidifying and dust-removing filter screen 3 is made of glass fiber cotton, polymer sponge or composite non-woven fabric, and the filter screen of the water filter screen 5 is made of stainless steel fine mesh, non-woven fabric, PP or PTFE; the outer casing 1 of the present invention can be provided with an independent outer box, which can be connected to the air duct or air channel, and can be powered by an external fan, or can be used directly in the air duct or air conditioning unit without an outer box.

[0024] In one embodiment, such as Figure 2 , Figure 4 and Figure 7As shown, the spray micro-holes 22 of the spray pipe 21 are located near the humidifying dust removal filter screen 3, ensuring that the airflow entering from the air inlet 18 can fully contact the spray water mist, while preventing the spray water mist from falling out of the housing 1, causing external water accumulation, which would also affect the dust removal effect. The spray micro-holes 22 of the water distribution pipe 7 are located at the top of the water distribution pipe 7, preventing the spray water from directly hitting the humidifying dust removal filter screen, damaging the filter material, and affecting the dust removal effect. The pore size of the spray micro-holes 22 is 0.1mm-0.5mm, preferably 0.2mm-0.3mm, which can produce uniform water mist with an average particle size of 50-150 micrometers, increasing the contact area between water and air, making it easier for dust particles in the air to be captured by water droplets, and improving the evaporation efficiency of water, thus achieving rapid humidification.

[0025] In one embodiment, such as Figure 1 and Figure 6 As shown, the filter material of the humidifying dust removal filter 3 is vertically folded. When water mist carrying dust and air pass through, the remaining dust collides with and is adsorbed by the moist filter material and is trapped. At the same time, the water that is not carried away by the air and remains on the filter material evaporates naturally under the action of airflow, realizing secondary humidification of the air and making the humidity output more uniform and natural. When the water distribution pipe 7 sprays, the excess water can flow down along the fold direction. The vertical fold angle of the humidifying dust removal filter 3 is in the range of 0.5°-30°, ensuring that the resistance of the humidifying dust removal filter is effectively reduced at different fold angles.

[0026] In one embodiment, such as Figure 1 and Figure 5 As shown, the top of the water tank 4 is provided with a support plate 13. The left and right ends of the support plate 13 are connected and fixed to the inner wall of the shell 1. The top of the support plate 13 is fixed with baffles 16 at the front and back. The bottom of the support plate 14 is provided with at least one support block 17. The middle of the support plate 13 is provided with at least one through hole 131. Below the through hole 131 of the support plate 13, there is a downward recessed groove 14. The bottom surface of the groove 14 is mesh. The water filter screen 5 is placed flat in the groove 14. The humidifying and dust-removing filter screen 3 is placed on the support plate 13. The humidifying and dust-removing filter screen 3 is fixed to the shell 1 with screws, which facilitates the disassembly of the water filter screen 5 and the humidifying and dust-removing filter screen 3 for cleaning or replacement. The mesh bottom surface of the through hole 131 and the groove 14 are designed to allow water to drip.

[0027] In one embodiment, such as Figure 2 and Figure 3 As shown, the air inlet 18 and the air outlet 19 are both located above the water tank 4 to prevent water in the water tank 4 from flowing out from the air inlet 18 or the air outlet 19.

[0028] In one embodiment, such as Figure 2 and Figure 3As shown, the side wall of the water tank 4 is provided with an outlet pipe 11 and an inlet pipe 12. The outlet pipe 11 is connected to the water tank 4 and is close to the bottom surface of the water tank 4. The inlet pipe 12 is connected to the water tank 4 and is located above the outlet pipe 11 and does not exceed the top of the water tank 4. One end of the inlet pipe 12 located inside the water tank 4 is provided with an automatic water replenishment valve 9. When the water level is lower than the set value, fresh water is automatically replenished to prevent the circulating water pump 6 from drying out and to maintain the water balance of the system.

[0029] In one embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, the side wall of the water tank 4 is provided with a fixing plate 15, and the bottom surface of the fixing plate 15 is fixed with a water level sensor 8. The water level sensor 8 extends into the water tank 4. The bottom of the water level sensor 8 is lower than the bottom of the water inlet pipe 12 and higher than the water inlet of the circulating water pump 6. The water level sensor 8 is provided with a water level upper limit switch and a water level lower limit switch. When the water level upper limit switch is triggered, the automatic water supply valve 9 is closed and the circulating water pump 6 is started. When the water level lower limit switch is triggered, the circulating water pump 6 stops working and the automatic water supply valve 9 is opened. This process is repeated.

[0030] Usage: Combine Figures 1-7 As shown, the spray pipe 21 is horizontally installed in the upper part of the housing 1. The spray micro-holes 22 on it spray out fine water mist. Behind it is the humidifying and dust-removing filter 3. After the air and water mist are mixed, they pass through the humidifying and dust-removing filter 3 to complete the capture of dust particles and the equalization of humidity. The water droplets mixed with dust pass through the water filter 5 above the water tank 4, which intercepts hair, fibers, and larger dust particles. The relatively clean water flows into the water tank 4 below. The circulating water pump 6 is placed in the water tank 4 and pumps the filtered clean water to the spray pipe 21 and the water distribution pipe 7 to complete the circulation. The water level sensor 8 and the automatic water replenishment valve 9 are responsible for maintaining the stability of the water level in the water tank 4.

[0031] The present invention has been described in the above-described embodiments; however, these embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. Conversely, any modifications and refinements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
