Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a water vapor atomization cleaning device under a blast furnace tank. Background Art

[0002] In the metallurgical industry, blast furnace ironmaking is one of the dustiest processes. The screening of raw materials and fuel beneath the blast furnace trough, coking and sintering, the operation of the blast furnace's conveyor belts, and the tapping of slag and iron in front of the blast furnace all generate large amounts of dust and small particles of industrial waste. Furthermore, the on-site working conditions are closed workshops. Although companies typically have dust collection ducts to absorb dust, the suction range of these ducts is limited and cannot fully cover all dust-generating spaces, resulting in large amounts of dust accumulation on the site. Generally speaking, accumulated dust is handled by employees sweeping with brooms and using compressed air. However, these methods are not only labor-intensive but also prone to dust. Dust repeatedly drifts through the air, forming new dust deposits, requiring repeated sweeping by employees. This vicious cycle makes the site difficult to clean, and the raised dust can affect the health of workers. Utility Model Content

[0003] The purpose of the utility model is to provide a water vapor atomizing cleaning device under the blast furnace trough which can suppress dust and improve the dust removal effect, so as to solve the problem in the above-mentioned background technology that dust repeatedly falls in the air and forms new dust accumulation, making it difficult to clean.

When the pressure in the water storage tank 1 is increased to a certain level, open the water outlet valve 35 and the inflation valve 46 to allow the water flowing out of the water outlet pipe 31 to be blown out. The pipe 43 blows and fuses to produce vaporized water, so that the water sprayed from the nozzle 33 is blown into an atomized state, and the required area is cleaned through the handheld hose 32, and the dust is suppressed by the water mist formed by the atomization; when the water in the water tank 1 is used up, the charging valve 46, the water outlet valve 35 and the air inlet valve 45 are closed in sequence, and then the pressure relief valve 15 is opened to relieve the pressure of the water tank 1. When the pressure relief reaches a certain level, the water inlet valve 22 and the stop valve 12 are opened for secondary water injection, and the above operation can be repeated after the water in the water tank 1 is full of water.
