Problems solved by technology

[0003] Conventional scrubbers are only suitable for the separation of mixed gases containing a small amount of dust. When the gas has a high dust content, multiple scrubbers need to be used in series, which not only occupies a large area, but also consumes a lot of energy.

Abstract

The invention discloses a washing tower which comprises an inner-layer main tower, a middle-layer preliminary washing tower and an outer-layer reflowing tower. An air inlet directly communicating to the outer part of the washing tower is formed in a position, close to the lower part, of the middle of the middle-layer preliminary washing tower; a preliminary washing tower bottom liquid and a sewageoutlet are arranged under the air inlet; a preliminary washing filler layer, a preliminary washing spraying device and an air hole communicating with the outer-layer reflowing tower are arranged above the air inlet; an adsorption cotton felt is arranged in the middle of the outer-layer reflowing tower; a gas channel directly communicating to the inner-layer main tower is arranged close to the bottom part; a main tower filler layer, a main tower spraying device, a defogging layer and an air outlet are sequentially arranged at a position, above the gas channel, in the inner-layer main tower; amain tower bottom liquid is arranged under the gas channel and is connected with the spraying device; an overflow pipe communicating with the middle-layer preliminary washing tower is arranged on theinner-layer main tower; a retaining cover with the density being smaller than water is hinged to the outer end of the overflow pipe. The washing tower provided by the invention is good in integrality,compact in structure and small in floor area; the preliminary washing tower bottom liquid is communicated with the main tower bottom liquid, so that no water circulating system needs to be independently arranged, and the energy is saved.

Description

technical field [0001] The application belongs to the technical field of environmental protection and relates to a washing tower. Background technique [0002] The scrubber is a new type of gas purification treatment equipment. It is improved on the basis of a floating packing layer gas purifier, and is widely used in the pretreatment of industrial waste gas purification, dust removal, etc., and the purification effect is very good. For the coal gasification process, coal gas scrubbing is inevitable, and this unit operation is used in any coal gasification technology. Because its working principle is similar to the washing process, it is named scrubber. [0003] Conventional scrubbers are only suitable for the separation of mixed gases containing a small amount of dust. When the gas has a high dust content, multiple scrubbers need to be used in series, which not only occupies a large area, but also consumes high energy consumption.
