Description

Technical Field

[0001] The invention relates to the technical field of environmental protection, and in particular to a water-filtering smoke treatment and purification device. Background Art

[0002] In industrial production, laboratory operations and other scenarios involving smoke, dust or harmful gas emissions, the effective removal of air pollutants is an important environmental protection requirement. Common smoke treatment technologies include electrostatic dust removal, activated carbon adsorption, spray tower wet treatment, etc. Among them, water-filtration smoke purification devices are widely used in welding smoke treatment, laser cutting smoke purification, chemical waste gas treatment, electronic manufacturing and laboratory exhaust systems due to their low energy consumption, high purification efficiency, and ability to remove particulate matter and some soluble gas pollutants.

[0003] Existing water-filter smoke purification devices mainly rely on water spraying, bubble washing or water curtain capture to remove smoke and gaseous pollutants. Although these methods can improve the purification effect to a certain extent, the following technical problems still exist: 1. Large particles in the smoke can easily follow the pipe into the filter device. These particles are difficult to decompose and are easily deposited inside the device. Existing devices fail to effectively intercept them; 2. Since the smoke flows at a high speed when entering the water filter device, unstable airflow is easily generated, which makes it impossible for some pollutants to be effectively settled, reducing the purification effect; 3. After the smoke passes through the water filter device, it usually carries a certain amount of water mist or tiny water droplets. These water droplets may contain adsorbed pollutants, forming secondary pollution during the discharge process, and even causing pollution deposition inside the pipeline.

[0004] In summary, while the existing water-filtration smoke treatment technology removes smoke and gaseous pollutants, it still faces problems such as unstable purification efficiency and secondary pollution. Therefore, how to optimize airflow control, improve purification effect and reduce secondary pollution has become the key technical direction for improving the current water-filtration smoke purification device. Summary of the invention

[0005] The present invention is intended to provide a water-filter type smoke treatment and purification device to solve the problems raised in the above-mentioned background technology. In this scheme, sponges are arranged inside the air intake duct and the exhaust duct. The sponge arranged in the air intake duct can effectively intercept the large particle mist in the smoke when it enters the purification box, and prevent the large particles that are difficult to degrade from entering the inner cavity of the purification box, causing them to be deposited in the purification box and difficult to clean. At the same time, it can effectively slow down the speed of smoke entering the purification box, avoid the generation of turbulent airflow, and enable the smoke to smoothly enter the inner cavity of the purification box to stabilize the purification effect. The sponge located in the exhaust duct is a wet sponge, and its porous structure is conducive to the condensation of water mist, so that small water droplets are absorbed or gathered into larger water droplets when passing through the sponge, so that they are more likely to flow back to the inside of the purification box, preventing them from being discharged with the exhaust gas, and avoiding the formation of secondary pollution. A pair of sponges are both directly placed and installed, so that they are easy to take out for regular replacement, and the sponge itself is low in cost, which effectively reduces the cost.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments:

[0025] like Figure 1-5 A water-filter type smoke treatment and purification device is shown, comprising a purification box 1 and a pair of sponges 5, wherein the two ends of the purification box 1 are respectively connected with an air intake duct 2 and an exhaust duct 3 which are connected with the inner cavity, and a water pump 11 is connected to the bottom end of the inner wall of the purification box 1, and a connecting pipe 15 is connected to the water pump 11, the connecting pipe 15 extends and spans across the top end of the inner wall of the purification box 1, and a plurality of transverse tubes 9 which are connected with the inner cavity are connected to the connecting pipe 15, and a plurality of atomizing nozzles 10 are connected to the bottom ends of the transverse tubes 9, the inner walls of the air intake duct 2 and the exhaust duct 3 are both connected with baffles 4, and the baffles 4 are arranged as hollow structures, and a pair of sponges 5 are respectively overlapped on the upper surfaces of the pair of baffles 4.

[0026] Existing water-filter smoke purification devices mainly rely on water spraying, bubble washing or water curtain capture to remove smoke and gaseous pollutants. Although these methods can improve the purification effect to a certain extent, while removing smoke and gaseous pollutants, they still face problems such as unstable purification efficiency and secondary pollution. Therefore, how to optimize airflow control, improve purification effect and reduce secondary pollution has become the key technical direction for improving current water-filter smoke purification devices.

[0027] In this embodiment, a plurality of universal wheels are connected to the bottom end of the purification box 1 to facilitate movement. When performing smoke purification, the user can connect the external exhaust fan to the air intake pipe 2 through an air supply pipe. The air intake pipe 2 is connected with a flange for facilitating the installation of the air supply pipe. The inner cavity of the purification box 1 is filled with water for purifying smoke. When smoke enters the inner cavity of the purification box 1 through the air intake pipe 2, the user starts the water pump 11 to introduce water into the connecting pipe 15, and then sprays it downward through the atomizing nozzles 10 on the plurality of transverse pipes 9 to form a plurality of water curtains. The smoke must pass through the plurality of water curtains before it can be discharged through the exhaust pipe 3. During this process, the pollutants and particles in the smoke can fully collide and mix with the water mist, so that the pollutants are degraded in the water, and clean air is discharged from the exhaust pipe 3.

[0028] In this embodiment, sponges 5 are provided inside the air intake duct 2 and the exhaust duct 3, and the baffle 4 is provided to play a positioning role. The sponge 5 provided in the air intake duct 2 can effectively intercept large particle mist in the smoke when the smoke enters the air intake duct 2, so that it is trapped on the surface of the sponge 5, thereby preventing large particles that are difficult to degrade from entering the inner cavity of the purification box 1, causing them to be deposited in the purification box 1 and difficult to clean. At the same time, the provision of the sponge 5 in the air intake duct 2 can effectively slow down the speed at which smoke enters the purification box 1, avoid the generation of turbulent airflow, and enable the smoke to smoothly enter the inner cavity of the purification box 1 and pass through the multi-layer water curtain at a uniform speed, thereby stabilizing the purification effect. The sponge 5 located in the exhaust duct 3 can be wetted by the user in advance. The porous structure of the wet sponge is conducive to the condensation of water mist, so that small water droplets are absorbed or gathered into larger water droplets when passing through the sponge, thereby making it easier to flow back to the interior of the purification box 1, preventing them from being discharged with the exhaust gas, and avoiding the formation of secondary pollution.

[0029] In this embodiment, the sponge 5 is installed by direct placement, which makes it easy to take out and replace regularly, and the sponge 5 itself is low in cost, which effectively reduces the cost.

[0030] The plurality of transverse tubes 9 are disposed perpendicular to the connecting tube 15 , and the plurality of transverse tubes 9 are arranged at equal distances.

[0031] In this embodiment, the water curtains formed under the multiple horizontal tubes 9 are arranged at equal intervals, evenly covering the inner cavity of the purification box 1, avoiding the occurrence of spraying dead corners, and the water mist is sprayed downward to collide with the water surface of the inner cavity of the purification box 1, further enhancing the water mist diffusion effect, allowing the smoke to fully contact the water mist, and increasing the degradation rate of pollutants.

[0032] The air intake duct 2 is arranged in an inclined shape, and the exhaust duct 3 is arranged in an L-shaped structure.

[0033] In this embodiment, the user can take out the sponge 5 in the air intake duct 2, and then directly inject water into the inner cavity of the purification box 1 through the air intake duct 2. The inclined setting of the air intake duct 2 makes the water injection process convenient. When the exhaust duct 3 is set in an L-shaped structure, the sponge 5 in the exhaust duct 3 can be placed horizontally and stably to avoid displacement caused by being blown by the exhaust airflow.

[0034] The outer end of the exhaust pipe 3 is connected to a water injection block 6, which is arranged in a ring structure and wrapped around the outer side of the exhaust pipe 3, and a water injection port 7 connected to the inner cavity is opened at the top of the water injection block 6. A plurality of water inlet holes 8 arranged equidistantly in a ring shape are opened on the exhaust pipe 3, and the water inlet holes 8 are arranged around the outer side of the sponge 5, and the plurality of water inlet holes 8 are all connected to the inner cavity of the water injection block 6.

[0035] In this embodiment, when the user wets the sponge 5 in the exhaust duct 3, water can be directly injected into the water injection block 6 through the water injection port 7, and then the injected water flow is evenly released to the surroundings of the sponge 5 through multiple water inlet holes 8, so that the sponge 5 absorbs water and is evenly wetted. In addition to ordinary water, the sponge 5 in the exhaust duct 3 can also be wetted with other liquids, such as disinfectant or bactericidal solution, which can inhibit the growth of bacteria, mold and algae and reduce microbial contamination inside the pipeline, or adsorption solution, which can enhance the absorption capacity of water mist for pollutants such as oil smoke and improve the purification effect. For example, acid-base regulating liquid can be used for specific waste gas treatment, such as alkaline aqueous solution absorbing acidic smoke, or acidic aqueous solution absorbing alkaline gas, to improve gas purification efficiency.

[0036] A scale rod 12 is slidably connected to the top of the purification box 1 near one end of the air inlet pipe 2. The scale rod 12 is vertically arranged, and the bottom end of the scale rod 12 extends to the bottom of the inner cavity of the purification box 1 and is connected to a floating plate 13.

[0037] In this embodiment, when the user fills water into the purification box 1 through the air inlet pipe 2, the rising water level will drive the float plate 13 to rise, and then lift the scale rod 12. The user can know the water level by observing the scale on the scale rod 12, so as to accurately control the water volume.

[0038] The bottom of the outer end of the purification box 1 is connected to a sewage pipe 14 connected to the inner cavity. A cover plate is detachably connected to the sewage pipe 14. The bottom end of the inner wall of the purification box 1 is inclined from high to low in the direction in which the sewage pipe 14 is set.

[0039] In this embodiment, the cover plate on the sewage pipe 14 has a blocking effect on it. By removing the cover plate, the user can make the water in the purification box 1 be discharged through the sewage pipe 14 along the inclined bottom inner wall thereof, thereby facilitating the user to regularly replace the water.

[0040] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
