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

Embodiment Construction

[0027] Attached figure 1 , Attached figure 2 , Attached image 3 It is a structural view of an embodiment of the present invention. The floating scrubber of the embodiment of the present invention is composed of a floating body (6), a floating body guide rail (3), an actuator (5), a rhombus-shaped contraction port (2), a sealing device (4), a frame (7), and an upper box. (1), the lower box (8), the water inlet (9) and other components. In the figure, the top a of the upper box body is the flue gas inlet, and f is the outlet after the flue gas is washed.

[0028] The floating body is composed of four movable petals. The petals can move laterally, but the gap between the petals is sealed with a sealing tape to form a square venturi. On the upper part of the venturi tube, there is a fixed rhombic constriction opening, which is a part of the guide rail, and the floating body moves along the generatrix direction of the rhombic constriction opening. Driven by the actuator, the ent...

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 venturi floating scrubber with a variable size, which belongs to the field of flue gas purification and washing technology and equipment. Background technique [0002] With increasing attention to environmental protection requirements, flue gas purification equipment for different treatment requirements has also been greatly developed, of which the Venturi scrubber has the highest purification efficiency. [0003] The traditional venturi is composed of a constriction, a throat, a water spray device and a diffuser. The principle of traditional venturi tube scrubbing flue gas is: [0004] The flue gas enters from the mouth of the shrinking tube and enters the throat after being gradually compressed, where the water sprayed by the water spray device and the flue gas are initially mixed. The flue gas compressed into the throat through the shrinking tube has a high flow velocity (not less than 50m / s), and the relative velocity of the gas...
