Description

Technical Field

[0001] This invention relates to the field of ventilation and dust removal systems for industrial and mining enterprises, and in particular to a non-continuous fully automatic water supply and sewage discharge type impact water bath dust removal and purification device. Background Technology

[0002] During the production processes of industrial and mining enterprises, a large amount of dust is generated in various stages of social production, including rock drilling, blasting, shoveling, and crushing in the mining industry; mineral storage, transportation, crushing, grinding, and washing in the mineral processing industry; coal storage, transportation, crushing, and grinding in the thermal power industry; cutting, grinding, and polishing of building materials in the construction industry; cement production and transfer; cutting, grinding, and polishing in the furniture industry; and component welding in the electronics industry. If the dust generated during the production processes of industrial and mining enterprises is not treated in a timely manner, it will inevitably lead to excessive dust levels in the working environment. This not only seriously affects the working environment but also threatens the health and safety of workers.

[0003] Currently, various industrial and mining enterprises mainly adopt multiple measures such as spray dust suppression, foam dust suppression, electrostatic precipitators, and ventilation dust suppression to reduce dust concentration and improve the working environment. Among them, ventilation dust suppression is widely used due to its simple structure, wide applicability, convenient operation and maintenance, and good dust removal effect, and is one of the most widely used dust suppression methods. This method mainly involves effectively controlling the dust source and guiding the dust-containing airflow to the dust collector through pipelines. The dust collector then purifies the dust in the polluted air. Conventional dust purification methods include mechanical, water bath, and bag filter types, each with its own characteristics and applicable scope, and all have achieved very good results. Water bath dust collectors are highly effective at purifying hygroscopic dust. However, they suffer from drawbacks: high water consumption and the formation of large amounts of sludge after dust collection, which is prone to accumulation and difficult to clean. Furthermore, insufficient contact between the polluted air and water prevents effective dust collection. Even with sufficient contact, incomplete dehydration after the water bath compromises purification efficiency. Therefore, high water consumption, difficulty in sludge discharge, insufficient contact between polluted air and water, and incomplete dehydration are all factors hindering the widespread application of water bath dust collectors. Effectively addressing these issues is crucial for their successful promotion and application. Summary of the Invention

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0034] Example 1

[0035] like Figure 1 As shown, a non-continuous fully automatic water supply and sewage discharge type impact water bath dust removal and purification device includes an exhaust air guide 2, and a bracket 3 is provided at the bottom of the exhaust air guide 2 for supporting the exhaust air guide 2. The exhaust air guide 2 is connected to a fan through an air duct.

[0036] A waste air wetting and inlet component 5 is provided on one side of the exhaust air guide 2. An external air guide body 51 is provided on the waste air wetting and inlet component 5, located on the outside of the exhaust air guide 2. An internal impactor 52 is provided on one side of the external air guide body 51, located on the inside of the exhaust air guide 2. The external air guide body 51 and the internal impactor 52 are connected. The internal impactor 52 has a reduced structure.

[0037] A water supply pipe 53 is provided at the top of the external air guide body 51. The water supply pipe 53 is connected to the external air guide body 51. An atomizing nozzle 56 is provided at one end of the water supply pipe 53, which is located inside the external air guide body 51.

[0038] The other end of the external air guide body 51 is provided with a waste air pipe, which is connected to the external air guide body 51, and the external air guide body 51 and the waste air pipe form a certain angle α (approximately 15°≤α≤17°).

[0039] Sewage air enters the external air guide body 51 through the sewage air duct. When the external air guide body 51 forms a certain angle with the sewage air duct, the sewage air entering the external air guide body 51 forms a vortex, which fully contacts the spray formed by the atomizing nozzle 56 inside the external air guide body 51, thus wetting the sewage air. The wetted sewage air enters the internal impact body 52. ​​The internal impact body 52 has a shrinking structure, which increases the wind speed of the wetted sewage air, forming an impact airflow. A manual ball valve 54 and a solenoid valve 55 are sequentially installed on the water supply pipeline 53. The water supply pipeline 53 is connected to the water supply system. The manual ball valve 54 realizes manual adjustment of the water supply, and the solenoid valve 55 is interlocked with the dust removal and purification system motor to realize automatic water supply.

[0040] A ventilation duct 1 is installed at the top of the exhaust guide 2, and the ventilation duct 1 is connected to the outlet of the exhaust guide 2, such as... Figure 2 As shown, a self-rotating dehydration assembly 4 is installed on the exhaust guide 2 at its outlet. The self-rotating dehydration assembly 4 has an upper air guide cover 41 and a lower air guide cover 42 below it. An inner sleeve plate 44 is installed around the outer ring of both the upper and lower air guide covers 41 and 42, connecting to their outer edges. Multiple guide vanes 45 are installed on the outer side of the inner sleeve plate 44, and an outer sleeve plate 43 is installed around each guide vane 45. The guide vanes 45 are connected to both the inner and outer sleeve plates 44 and 43. Air inlets 46 are installed on both the upper and lower air guide covers 41 and 42, and a distance is provided between them. Figure 2 , Figure 3 As shown.

[0041] The upper air guide cover 41 and the lower air guide cover 42 are welded to the inner sleeve plate 44. The air guide vanes 45 are evenly welded to the inner sleeve plate 44 and the outer sleeve plate 43, with 6 to 8 air guide vanes being preferable. The outer sleeve plate 43 is fixed to the exhaust guide fluid 2 with 6 to 8 bolts. The self-rotating dehydration assembly 4 can convert the water-containing fresh air into a rotating airflow through the action of the air guide vanes 45. The strong centrifugal force of the rotating airflow is used to dehydrate the fresh air. The dehydrated fresh air is then guided and collected by the exhaust guide fluid 2 and enters the ventilation duct 1.

[0042] A water bath component 6 is provided at the bottom of the exhaust air guide 2. The water bath component 6 is located below the waste air wetting and inlet component 5. The waste air wetting and inlet component 5, the water bath component 6, and the exhaust air guide 2 are all connected.

[0043] A sludge collector 61 is provided on the water bath assembly 6. A sludge conduit 62 is provided at the bottom of the sludge collector 61. A cleaning and drain valve 63 is provided on one side of the sludge conduit 62 at the bottom of the sludge collector 61.

[0044] Under negative pressure, the high-speed sewage airflow impacts the water in the exhaust guide 2, forming an air-water mixture. Dust is absorbed by the water and, after passing through the spin-type dewatering component 4, the dust-containing sewage is deposited along the inner wall of the exhaust guide 2 into the sludge collector 61. Under the action of water flow, it enters the automatic sewage discharge component 7 along the sludge conduit 62.

[0045] The automatic sewage discharge assembly 7 is equipped with a water tank 71, and an overflow pipe 72 is installed inside the water tank 71. A fixing sleeve 73 is installed at the bottom of the water tank 71, and the fixing sleeve 73 is fitted onto the overflow pipe 72. The outer side of the fixing sleeve 73 is threaded, and a fixing nut 74 is fitted onto the fixing sleeve 73 to secure the overflow pipe 72. A protrusion is provided on the top of the fixing sleeve 73 to fix the fixing sleeve 73 inside the water tank 71. Figure 4 As shown.

[0046] Sludge containing dust enters water tank 71 through sludge conduit 62. As the water supply increases, the water level in water tank 71 rises continuously. When the water level is higher than the upper end of overflow pipe 72, sludge water containing a large amount of sludge is discharged along overflow pipe 72, activating the automatic sewage discharge function. Fixing sleeve 73 and fixing nut 74 are used to adjust the height of overflow pipe 72 to control the liquid level in the dust collector and ensure the dust removal effect.

[0047] Therefore, the present invention adopts the above-mentioned non-continuous fully automatic water supply and sewage discharge type impact water bath dust removal and purification device, which reduces the water supply, realizes automatic sludge cleaning, ensures full contact between sewage air and water, and ensures the completion of air dehydration after purification.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
