Jet dust collection and removal device

Abstract

The invention discloses a jet dust collection and removal device, which is mainly used for dust collection and removal in a dust pulping process. The device includes a jet dust collection component, a mixing chamber, a gas-water separation component, a spraying component and a spraying control component. The liquid controlled by a jet control component in the jet dust collection component passes through a dust air outlet at a high speed and brings dust air into the mixing chamber, in which the dust and the liquid are fully mixed. When the dust-absorbing liquid and air rise to the gas-water separation component, the air naturally rises to the spraying component and undergoes filtration and spraying so as to become clean air, which is then discharged. The dust-containing liquid falls back to the separation component, and flows back to a preparation tank to further serve as a material for use. The invention can continuously operate for a long time, reduce environmental pollution, protect the physical and mental health of workers, and also can make dust flow back for use, reduce material waste, and maintain a balanced pulping concentration.

Description

technical field [0001] The invention relates to a dust suction and dust removal device. In particular, it relates to a device for vacuuming and removing dust by using the spilled dust generated during the slurrying operation of insoluble powder. It belongs to the field of environmental protection. Background technique [0002] At present, in the pulping process of insoluble powders at home and abroad, the overflowing dust basically adopts two methods of bag dust removal and water mist dust removal. The working method mainly depends on the positive pressure of the gas in the preparation tank to discharge the gas. The gas is entrained with water vapor at the same time, the dust is easy to adhere to the surface of the bag and it is difficult to remove, the dust bag will be blocked soon, and manual treatment is more frequent, otherwise the dust removal effect will be greatly affected, environmental pollution will easily occur, and the loss and waste of the working medium will a...

[0002] At present, in the pulping process of insoluble powders at home and abroad, the overflowing dust basically adopts two methods of bag dust removal and water mist dust removal. The working method mainly depends on the positive pressure of the gas in the preparation tank to discharge the gas. The gas is entrained with water vapor at the same time, the dust is easy to adhere to the surface of the bag and it is difficult to remove, the dust bag will be blocked soon, and manual treatment is more frequent, otherwise the dust removal effect will be greatly affected, environmental pollution will easily occur, and the loss and waste of the working medium will also be increased; The fog dust removal method is difficult to achieve the dust removal effect for difficult-to-wet powder materials, and the continuous operation of the equipment is likely to cause environmental pollution

For example, a large amount of powdered charcoal is currently used in tap water plants to ensure that the water quality is up to standard, but the powdered charcoal is not easy to wet, and a large amount of black dust overflows during the pulping process. The original dust removal method is not effective, affects environmental sanitation, and causes serious health problems for workers. Large impact, will also increase the loss of raw materials

[0003] Therefore, the existing dust removal technology for insoluble and difficult-to-moisture dust in the pulping process is not easy to separate the gas and powder, which is easy to cause: (1), the existing dust removal equipment is prone to failure, and the dust removal effect is not good; (2), work The deterioration of the environment is not conducive to the health of workers, and even causes environmental pollution; (3), the loss of materials in the production process is large, and it is difficult to maintain the pulping concentration
