Description

Technical Field

[0001] This utility model belongs to the technical field of purification devices, specifically relating to a wet explosion-proof central dust purification device. Background Technology

[0002] For metal dust such as aluminum and magnesium, as well as other relatively heavy explosive dust, if these dusts and particles are not cleaned up in time, they can easily cause accidents such as explosions when they reach a certain concentration. At the same time, these dusts, particles, and harmful gases in the exhaust gas can affect the health of employees. If these harmful substances and gases are directly emitted into the air, they will pollute the surrounding environment. Therefore, it is necessary to purify the harmful substances and gases generated in the production process.

[0003] However, existing equipment cannot effectively purify harmful waste gases, dust, and particulate matter generated during production. Therefore, there is an urgent need to develop a new device to optimize and change the current situation. Utility Model Content

[0004] In view of the problems mentioned above in the background technology, the purpose of this utility model is to provide a wet explosion-proof central dust purification device.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A wet explosion-proof central dust purification device includes a housing, an inlet pipe and an outlet pipe connected to the housing, a stuffing box installed at the inlet end of the outlet pipe, a partition installed inside the housing at the outlet end of the inlet pipe, a baffle installed inside the housing on the side of the partition, a retaining plate installed inside the housing on the side of the baffle, the baffle being located between the retaining plate and the partition, water passage holes provided on the lower sides of the baffle and the retaining plate, and a filter screen installed between the baffle and the retaining plate.

[0007] A water storage tank is installed on the lower side of the housing. The water storage tank is equipped with a placement box, and a filter media box is placed inside the placement box. A water pipe is connected between the placement box and the bottom of the housing. A water pump is installed inside the water storage tank. A water delivery pipe is connected to the output end of the water pump. A spray pipe is connected to the output end of the water delivery pipe. The spray pipe is located at the top inside the housing.

[0008] Furthermore, the top of the baffle is an inclined plate that slopes towards the card plate. This design expands the range of the spray pipe and enhances the purification and neutralization effect.

[0009] Furthermore, the water tank is equipped with a condenser and a temperature sensor, and the housing is equipped with a control panel. This design allows the liquid temperature to be reduced by injecting a condensing medium into the condenser to exchange heat when the temperature of the liquid being purified is too high.

[0010] Furthermore, the packing box, the filter screen, and the filter media box are all installed in corresponding positions by a pull-in method. After installation, the packing box, the filter screen, and the filter media box are all sealed. This design facilitates the disassembly, cleaning, and replacement of the packing box, the filter screen, and the filter media box.

[0011] Furthermore, the spray pipe is densely equipped with more spray heads between the baffle and the clamping plate. This design increases the density of the liquid in the directly entering gas, ensuring the purification and neutralization effect.

[0012] The beneficial effects of using this utility model are as follows:

[0013] With the structural design of this utility model, after the gas enters the air passage formed by the partition and baffle, it is subjected to wet treatment by the spray pipe on the upper side to prevent explosion. The liquid accumulated at the bottom of the shell also plays a role in purification and neutralization.

[0014] The structural design of this utility model ensures the purification effect through the combined effects of the spray pipe, the liquid inside the shell, and the packing box.

[0015] With the structural design of this utility model, the filter media box and filter screen can effectively block particles in the dust during reflux, preventing the liquid used for purification from failing too quickly and ensuring its service life. Attached Figure Description

[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, the wet explosion-proof central dust purification device of this utility model includes a housing 1, an air inlet pipe 2 and an air outlet pipe 3 connected to the housing 1, a stuffing box 4 installed at the input end of the air outlet pipe 3, a partition 5 installed inside the housing 1 at the output end of the air inlet pipe 2, a baffle 6 installed inside the housing 1 on the side of the partition 5, a retaining plate 7 installed inside the housing 1 on the side of the baffle 6, the baffle 6 being located between the retaining plate 7 and the partition 5, a water passage hole 8 provided on the lower side of the baffle 6 and the retaining plate 7, and a filter screen 9 installed between the baffle 6 and the retaining plate 7.

[0024] A water storage tank 10 is installed on the lower side of the housing 1. The water storage tank 10 is provided with a placement box 11. A filter material box 12 is placed inside the placement box 11. A water pipe 13 is connected between the placement box 11 and the bottom of the housing 1. A water pump 14 is installed inside the water storage tank 10. A water delivery pipe 15 is connected to the output end of the water pump 14. A spray pipe 16 is connected to the output end of the water delivery pipe 15. The spray pipe 16 is located at the top of the inner part of the housing 1.

[0025] In this embodiment, when using the wet explosion-proof central dust purification device, the water pump 14 operates, sending the liquid used for purification and neutralization in the water storage tank 10 through the water delivery pipe 15 into the spray pipe 16 for spraying. As a result, the inside of the shell 1 is densely covered with water mist. The gas enters from the air inlet pipe 2 into the air passage formed between the partition 5 and the baffle 6. While the spray pipe 16 backflushes, cools, purifies, and neutralizes the incoming gas, the liquid accumulated at the bottom of the shell 1 also serves to neutralize the dust, achieving the purpose of explosion protection. After the gas is purified by the water mist, it is then further purified by the packing in the packing box 4 before being discharged from the air outlet pipe 3.

[0026] It should be noted that the rate of liquid sprayed from the spray pipe 16 is slightly greater than or equal to the rate of water flow from the water pipe 13; otherwise, it will be impossible to achieve the purpose of accumulating inside the shell 1, or there may be excessive accumulation. This point is easy for those skilled in the art to understand.

[0027] During the reflux, filter 9 can effectively adsorb large particles in the dust, preventing the refluxed liquid from containing a large amount of dust that would affect the purification and neutralization effect. The filter media box 12 further enhances the adsorption effect.

[0028] Preferably, the top of the baffle 6 is an inclined plate that slopes towards the plate 7. This design expands the range of the spray pipe 16 and enhances the purification and neutralization effect. In fact, the structure of the baffle 6 can also be considered according to the specific situation.

[0029] The preferred design is that the water tank 10 is equipped with a condenser 17 and a temperature sensor 18, and the housing 1 is equipped with a control panel 19. With this design, when the temperature of the liquid used for purification is too high, the liquid temperature can be reduced by injecting a condensing medium into the condenser 17 to exchange heat. In fact, temperature control measures can also be considered according to specific circumstances.

[0030] Preferably, the packing box 4, filter screen 9 and filter media box 12 are all installed in their corresponding positions by a pull-in method. After installation, the packing box 4, filter screen 9 and filter media box 12 are all sealed. This design facilitates the disassembly, cleaning and replacement of the packing box 4, filter screen 9 and filter media box 12. In fact, the installation sealing structure of the packing box 4, filter screen 9 and filter media box 12 can also be considered according to the specific situation.

[0031] Preferably, more spray heads are densely installed on the spray pipe 16 between the baffle 6 and the clamping plate 7. This design increases the density of the liquid in the directly entering gas, ensuring the purification and neutralization effect. In fact, the number and position of the spray heads on the spray pipe 16 can also be considered according to the specific situation.

[0032] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
