Floating washing apparatus

Abstract

The invention relates to a floating washing apparatus, belonging to the field of smoke purification and washing technology and equipment. The floating washing apparatus of the invention comprises a floating body (6), a floating body guideway (3), an actuating mechanism (5), a tailin-shaped contraction opening (2), a sealing device (4), a machine stander (7), an upper box body (1), a lower box body (8), a water inlet (9), and the like, wherein the floating body is a venturi tube comprising two to six moveable sections, and the circulation area of the floating body (the venturi tube ) can be adjusted on the length of an entire axial line according to the variation of air volume, so as to lead the circulation area to adapt to the processed air volume, thereby keeping stable and highly efficient working and low energy consumption. The apparatus can be widely applied to the washing treatment of industrial waste gas, is especially suitable for the treatment of dusty smoke with heavy fluctuation of air volume, and is also suitable for the occasion which needs to adjust the purification efficiency according to the change of smoke condition, thereby realizing economical running.

Description

technical field [0001] The invention relates to a floating scrubber of a venturi tube with variable dimensions, which belongs to the field of flue gas purification and scrubbing technology and equipment. Background technique [0002] With the increasing emphasis on environmental protection requirements, flue gas purification equipment for different treatment requirements has also been greatly developed, among which Venturi scrubbers have the highest purification efficiency. [0003] A traditional Venturi consists of a constriction, a throat, a sprinkler, and a diffuser. The principle of traditional Venturi tube scrubbing flue gas is: [0004] The flue gas enters from the mouth of the contraction tube, and enters the throat pipe after being gradually compressed, where the water sprayed by the water spray device is initially mixed with the flue gas. The flue gas compressed by the shrink tube and entering the throat has a very high flow velocity (not less than 50m / s), and the...

AI Technical Summary

Problems solved by technology

Such a Venturi tube is a variant structure, which weakens the recovery function of the traditional Venturi diffusion tube for pressure drop. Significant increase in losses

[0006] High-efficiency Venturi scrubbers belong to a type of equipment with relatively large power consumption, and the existing adjustable Venturi scrubbers increase a lot of power consumption, thus limiting its application to a large extent
