Spraying foam desulfurization dust remover

Abstract

The invention relates to the field of desulfurization and dust removal, in particular to a spraying foam desulfurization and dust remover, which comprises a tank body structure, a water treatment structure, a filtering structure, a dust removal structure, a flow limiting structure and a foam blocking structure. In the dust remover, the filtering structure can be used for storing and precipitatingsewage discharged by the dust removal structure, impurities in the sewage are precipitated and filtered to be changed into reusable water again to be used by the dust removal structure, so that use ofthe water by the dust removal structure is effectively reduced, meanwhile, the filtering structure can reduce the flow speed of the sewage discharged by the dust removal structure, which facilitatesfiltration and precipitation of the sewage; furthermore, due to the foam blocking structure, residual foam is prevented from entering a pipeline of the water treatment structure to cause unclean ascending water, so that the dust removal effect of the dust removal structure is reduced, and meanwhile, the foam blocking structure can delay the flow speed of the water to enable the water to be settledmore completely in the filtering structure; in addition, by using the flow limiting structure, the water inlet amount can be automatically adjusted by controlling the flow speed of the entering gas,so that the dust removal effect of the dust removal structure is better.

Description

technical field [0001] The invention relates to the field of desulfurization and dust removal, in particular to a spray foam desulfurization and dust removal device. Background technique [0002] The foam desulfurization dust collector is the sieve tray tower, which is composed of a vertical empty tower with horizontal hollow plates inside. In the foam desulfurization dust collector, the air flow passes through the water layer on the sieve plate from bottom to top. When the air flow velocity is controlled within a certain range, a foam layer can be formed on the sieve plate. The bubbles in the foam layer are continuously broken and merged. and regenerated. After the airflow passes through this layer of foam, the dust is trapped and the gas is purified. Water leaks through the sieve plate into the water tank at the lower part of the dust collector, and the water is continuously replenished on the sieve plate. When the amount of replenished water is greater than the leaked w...

Problems solved by technology

[0003] However, because the overflow foam desulfurization dust collector needs to keep injecting water to maintain the height of the water surface, a lot of water will be discharged at the same time, resulting in a waste of water resources, which does not meet the requirements of sustainable development, and the water intake cannot change with the intake volume. Make appropriate adjustments, can not achieve the best dust removal effect
