Description

Technical Field

[0001] The utility model belongs to the technical field of water curtain dust removal, and particularly relates to an industrial water curtain dust removal device. Background Art

[0002] As an efficient air purification device, the water curtain dust removal machine on the market now reflects the effective control and treatment of environmental pollution in its working principle and structural design. The working principle of the water curtain dust removal machine is mainly based on the full mixing of the water curtain and the dust-containing air. By using the combination of water droplets and particulate matter in the soot, the dust can be removed, thereby improving the dust removal efficiency. Specifically, modern designed water curtain dust removal equipment pays more attention to efficiency and effect. For example, some designs incorporate humidifying wet membranes and air guiding structures, which can further improve the dust removal efficiency and ensure air circulation. In addition, some devices are also equipped with air outlets, air inlets, corresponding air guiding vanes and auxiliary baffles, which all make the dust removal process more efficient and stable. The water curtain dust removal machine is applicable to a variety of scenarios, such as environments with a lot of waste gas generated in petrochemical industry, machinery manufacturing factories, spraying workshops, laser cutting, etc.

[0003] At the present stage, the curtain dust removal device effectively reduces the dust content in the air and protects workers from harmful substances. In addition, it can also reduce environmental pollution and improve air quality. However, although the water curtain machine has many advantages, it also has the following disadvantages: 1. High maintenance cost. The filter screen in the water curtain machine dust removal system needs to be cleaned and replaced regularly to maintain the efficient operation of the system. The workload of cleaning and replacing the filter screen is relatively large, and a certain amount of manpower and time need to be invested; 2. There are potential safety hazards. Although the water curtain machine can adsorb waste paint and waste gas and prevent the fire risk caused by spraying, if the circulating water system is not smooth and the flow rate, flow velocity and pressure control are unreasonable, the paint mist, some particles and fluff in the spraying room cannot be taken away in time, and the environment cannot be purified; 3. High water consumption. The working principle of the water curtain machine is to use self-priming and circulating filtration by a water pump. Although it saves electricity, compared with some special working environments, the water consumption of the water curtain machine is relatively large; 4. Impact on the environment. The water curtain machine requires a large amount of water during use, which may cause a certain burden on the environment. In addition, if the waste water is not properly treated, it may cause environmental pollution; 5. Limited adaptability. For some special operations, the water curtain machine may not be able to provide effective dust removal effect. Summary of the Utility Model

An overflow water groove 4 is opened at the upper end of the water curtain overflow plate 3. The overflow water tray is fixedly connected to the side wall surface of the coarse filtration chamber and is adapted to the water curtain overflow plate 3.

[0027] Among them, the height of the overflow water tray 14 is lower than the bottom end of the water curtain overflow plate, and the lowermost end of the overflow water tray 14 extends beyond the lowermost end of the water curtain overflow plate 3. Through the setting of the coarse filtration component, the flue gas is evenly diffused around, so as to avoid the situation that the waste flue gas directly hits the first water curtain and destroys the water flow, resulting in uneven filtration and unsatisfactory effects.

[0028] As Figure 3-4 shown, the fine filtration component includes a spray water curtain plate 10, a spray head 9, a breathable water-blocking plate 8, and an upper cover plate 6. The spray water curtain plates are respectively fixedly connected to the inner wall surface of the fine filtration chamber. The breathable water-blocking plate 8 is fixedly connected inside the fine filtration chamber. The upper cover plate 6 is fixedly connected to the upper end of the housing 0. The spray head 9 is arranged between the breathable water-blocking plate 8 and the spray water curtain plate 10, and the spray head 9 is sequentially connected through a conduit. A filter screen 7 is arranged between the breathable water-blocking plate 8 and the upper cover plate 6.

[0032] Among them, the usage method of an industrial water curtain dust removal device is as follows:

[0033] 1) Gas dust particles enter from the air inlet 1. When they encounter the air-blocking baffle 2, the flue gas is evenly diffused around, avoiding the situation that the waste flue gas directly hits the water curtain overflow plate 3 and then destroys the first water curtain water flow, resulting in uneven filtration and unsatisfactory effects.

[0034] 2) The waste flue gas starts the first filtration through the water curtain formed by the water overflowing from the first water curtain overflow plate 3 and overflowing from the overflow water tank 4. After the filtration is completed, it reaches below the spray water curtain plate 10 along the space under the middle vertical plate, and the waste flue gas rises; then the second filtration is carried out, and it is filtered through three water curtains formed by the water sprayed from the upper spray.

[0035] 3) The waste flue gas continues to rise and is filtered for the third time through the umbrella-shaped spray formed by the spray heads arranged in a row. After the filtration is completed, it passes through the air-permeable holes of the air-permeable water-blocking plate 8, and then is finally filtered by the filter net 7 and discharged through the air outlet 5.

[0036] Among them, during the above process, the water in the water tank 12 is filled into the overflow water tank 4 and the spray heads 9 by the water pump 11 to ensure repeated use in a cycle.

[0037] When specifically implemented, when harmful gases need to be filtered, neutralizing agents are added to the circulating components in the water curtain machine to achieve the effect of neutralizing harmful gases and making the emissions meet the standards.
