Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a labyrinth type water body adsorption dust removal equipment. Background Art

[0002] Dust removal equipment plays an important role in industrial production. Common dust removal equipment includes plate dust collectors, bag dust collectors, etc. These dust collectors all have some disadvantages. For example, although plate dust collectors are easy to clean, they have low filtering efficiency for tiny particles; bag dust collectors have poor treatment effects on high-concentration particulate matter, especially in the south where the weather is poor and the ambient humidity reaches about 85%, dust will stick together, making it even more difficult for these dust removal equipment to achieve effective dust removal.

[0003] Chinese patent CN202878902U discloses a vacuum adsorption noise reduction dust removal device, which achieves dust removal effect by passing dust-laden airflow into a water film dust removal tank and utilizing the water adsorption effect. However, since the centrifugal fan is arranged at the front end of the water film dust removal tank, the dust-laden airflow first passes through the centrifugal fan before entering the water film dust removal tank for adsorption and dust removal. This causes the centrifugal fan to be impacted and damaged by particles in the airflow, reducing the service life of the centrifugal fan. In addition, after the dust-laden airflow passes through the water adsorption twice, the dust removal effect is not significantly improved. Utility Model Content

[0004] The utility model aims to provide a labyrinth-type water body adsorption and dust removal device to optimize the adsorption effect of dust particles and achieve the purpose of improving the dust removal effect.

[0006] Preferably, the equipment body is also provided with a water spraying device for spraying water mist toward the air inlet end of the maze dehydration chamber.

[0007] More preferably, the first separation chamber, the second separation chamber and the labyrinth dehydration chamber are all cylindrical structures, and the axial direction of the air inlet is perpendicular to the axial direction of the first separation chamber, so that the airflow flows in a spiral path after entering the first separation chamber.

[0009] More preferably, the air inlet end of the air guide duct extends downward from the top center of the equipment body and extends to the bottom of the maze dehydration chamber until it is close to the dust adsorption liquid.

[0010] More preferably, an exhaust fan is connected between the air guide duct and the exhaust box.

[0011] More preferably, the dust adsorbing liquid is water.

[0012] More preferably, an ash discharge port is provided at the bottom of the first separation chamber.

[0021] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0022] It should be noted in advance that, in the present utility model, unless otherwise clearly specified and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. In addition, in the present utility model, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature can include the first and second features directly contacting, and can also include the first and second features not being in direct contact but contacting through another feature between them.

[0023] like Figure 1 to Figure 2 As shown, the labyrinth water body adsorption dust removal equipment includes an equipment body, the equipment body is provided with an air inlet 4, and the equipment body is provided with a first separation chamber 1, a second separation chamber 2 and a labyrinth dehydration chamber 3 connected to the air inlet 4. The air inlet ends of the first separation chamber 1, the second separation chamber 2 and the labyrinth dehydration chamber 3 are connected in sequence in an up-and-down staggered form to guide the airflow to flow along a Z-shaped route for multiple times and reach the end of the labyrinth dehydration chamber 3. The bottom of the labyrinth dehydration chamber 3 is provided with a dust adsorption liquid 6 for multiple downward impacts during the flow of the airflow. The end of the labyrinth dehydration chamber 3 is connected to an exhaust box 8 through an air duct 7. A layer of fog absorbing cotton 9 for filtering is provided in the exhaust box 8. The airflow enters the bottom of the exhaust box 8 through the air duct 7 and is discharged from the upper end of the exhaust box 8 after being filtered by the fog absorbing cotton 9.

[0024] In the above structure, the first separation chamber 1, the second separation chamber 2 and the maze dehydration chamber 3 are all cylindrical structures, and the axial direction of the air inlet 4 is perpendicular to the axial direction of the first separation chamber 1, so that the airflow flows in a spiral path after entering the first separation chamber 1. In this way, the particulate matter in the airflow will perform a spiral wall motion and finally move downward under the action of gravity. By setting the bottom surface of the first separation chamber as an inclined surface and providing an ash discharge port 5 at the bottom, large particles of dust can be concentrated and fall at the ash discharge port 5, which is convenient for regular cleaning.

[0025] In order to improve the dust removal effect, the equipment body is also provided with a water spraying device 10 for spraying water mist to the air inlet end of the labyrinth dehydration chamber 3. By spraying water mist, the airflow entering the labyrinth dehydration chamber 3 is formed into a mixed state of wind, water and mist, so that the dust particles in the airflow are adsorbed by the water mist in advance. Then, when the airflow contacts the dust adsorption liquid 6 at the bottom, it will be easier for the dust adsorption liquid 6 to adsorb the dust particles and impurities in the airflow. In addition, when the dust-laden airflow passes through, spraying water mist toward the airflow can also play the following roles:

[0026] Capture of coarse particles: Small water droplets in water mist can adhere to large dust particles, increase the weight and adhesion of the dust, and make the dust easy to be filtered and captured. Increase filtration efficiency: Water droplets in water mist can increase the humidity in the airflow, reduce static electricity in the air, and reduce electrostatic adsorption between particles, thereby improving filtration efficiency. Reduce temperature: In a high temperature environment, the temperature of the dust-laden airflow can be reduced to an acceptable range by spraying water mist to ensure the normal operation of the equipment. Suppress the risk of explosion and fire: For flammable and explosive particles, spraying water mist can reduce the risk of explosion and fire by absorbing heat and lowering the temperature of the particles. Reduce particle concentration: Water droplets in water mist can directly combine with particles in the air to cause them to deposit, thereby reducing the concentration of particles in the airflow.

[0027] Furthermore, the second separation chamber 2 is installed on the top of the first separation chamber 1 with its air inlet facing downward, and the air inlet of the labyrinth dehydration chamber 3 extends upward into the second separation chamber 2. The air inlet end of the air duct 7 extends downward from the top center of the device body and extends to the bottom of the labyrinth dehydration chamber 3 until it is close to the dust adsorption liquid 6. The dust adsorption liquid 6 can be water. In addition, an exhaust fan 11 is connected between the air duct 7 and the exhaust box 8. In addition, there is usually a main exhaust fan in the application scenario of the entire device, and the exhaust fan 11 acts as a branch unit to improve the fluidity of the airflow.

[0028] In the final stage, the airflow enters the bottom of the exhaust box 8 through the air guide pipe 7 and is discharged from the upper end of the exhaust box 8 after being filtered by the mist absorbing cotton 9. This setting has the following effects:

[0029] Capture of particles: Mist absorbent cotton is a highly efficient fiber filter material that can effectively capture and fix particles so that they can no longer be discharged into the atmosphere. This helps improve air quality and reduce the impact on human health. Reduce environmental pollution: Through filtration, the concentration of particles emitted into the atmosphere is greatly reduced, reducing pollution to the surrounding environment and vegetation, and protecting the health and sustainability of the environment. Improve safety: Through filtration, the concentration of particles in the exhaust system can be effectively reduced, reducing the risk of fire and explosion, and ensuring the safety of the workplace. Reduce dust concentration in the work area: The filtered airflow is discharged to the work area, reducing the dust concentration in the work area, improving the working environment, and protecting the health of employees. Energy saving and environmental protection: Using mist absorbent cotton to filter particles can reduce energy consumption, especially in the capture and fixation of large particles. This helps reduce energy waste and carbon emissions, in line with the requirements of sustainable development.

[0030] The working principle of the labyrinth-type water body adsorption dust removal equipment provided in the above embodiment is: Figure 2As shown, the general airflow route is marked in the figure. First, the dust-laden airflow enters the first separation chamber 1 along the tangential direction through the air inlet 4 to form a spiral flow form, so that the large dust particles in the airflow flow along the wall and settle to the bottom of the first separation chamber 1, while the airflow continues to flow and enters the second separation chamber 2 upward, and then continues to flow along the Z-shaped route and enters the labyrinth dehydration chamber 3 downward. At this time, it will also be affected by the water mist sprayed by the water spraying device 10, forming a wind-water-mist mixture, continue to flow downward and hit the dust adsorption liquid 6 at the bottom of the labyrinth dehydration chamber 3, and then flow along the Z-shaped route network, and pass through such flow paths many times, thereby hitting the dust adsorption liquid 6 many times, and finally enter the air duct 7, and then further flow to the bottom of the exhaust box 8, and be discharged from the upper end of the exhaust box 8 after being filtered by the mist-absorbing cotton 9.

[0031] In order to make it easier for ordinary technicians in this field to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and the above-mentioned embodiments are better implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
