Abstract

The invention relates to a dehydration device of a wet-method smoke purifier. The dehydration device mainly comprises a cylindrical wet-method smoke purifier (200) which is arranged on a foundation base (100), an inner spiral tube (300) which is arranged in a cylinder of the wet-method smoke purifier (200) and a swirler (400) which is arranged in the inner middle part of the cylinder of the wet-method smoke purifier (200) and can generate a swirling smoke flow. The wet-method gas purifier can produce a great amount of steam by adopting the impact, water membrane or sprinkling technologies, the steam discharged from a chimney carries a plurality of light-weight pollutants such as organic heterocyclic compounds, PM2.5 and the like, a desulphurization and denitration tower has the problems of gypsum rain and ammonium loss, which are reasons of white pollution and local smog. Therefor, by adopting the dehydration device of the wet-method smoke purifier, although the problem that the steam is discharged from the wet-method smoke purifier cannot be completely prevented, the discharged steam is minimized, so that the harm of the white pollution can be alleviated.

Description

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.

Fig. 1 is front view of the present invention.

Fig. 2 is top view of the present invention.

In figure: 1-smoke inlet; 2-water body; 3-spray system; 4-circulating pump; The outer water fender of 5-; 6-exhanst gas outlet; Water fender in 7-; 8-bullet; 9-delivery port; 10-keeps out the wind and emits; 11-torus; 12-guide vane; 100-sole plate; 200-Wet process flue gas purifier; 300-inward turning cylinder; 400-cyclone.

Detailed description of the invention

As shown in Figure 1 and Figure 2, during use: the flue gas containing multiple pollutant is entered among the described Wet process flue gas purifier (200) that is seated on sole plate (100) by smoke inlet (1), downward impact is positioned at described sole plate (100) water body (2), produces a large amount of air water stream; In order to purifying smoke, remove the pollutant in flue gas, subsequently by circulating pump (4) by spray system (3), also in described Wet process flue gas purifier (200) rising air water stream spray water body (2), produce a large amount of steam.When the flue gas containing a large amount of steam continues to rise in described Wet process flue gas purifier (200), during by described cyclone (400), will through being fixedly installed on the guide vane (12) of some rotation directions between torus (11) on described cyclone (400) and described Wet process flue gas purifier (200) inwall, because guide vane (12) is all that rotation direction arranges clockwise or counterclockwise, the air water stream of rotation can be produced, due to the effect that gas can occur centrifugal force, water is separated, remove a part of steam; Rotary pneumatic current continue to rotate and rise, and in the outer water fender (5) of some rotation directions and rotation direction, water fender (7) Shi Douhui plays dehydration, removes a part of steam; When humid flue gas enters after inward turning cylinder (300) downwards through water fender in rotation direction (7), flow velocity is accelerated, and centrifugal force is also strengthened, dewatering efficiency reaches maximum, again when exhanst gas outlet (6) enters air, there is no how much steam, reach dehydration object.The steam removed through inward turning cylinder (300) forms current, tubular bullet (8) can be flowed to along the inwall of inward turning cylinder (300), keep out the wind through delivery port (9) and taper and emit (10), finally fall into the water body (2) of described Wet process flue gas purifier (200) bottom.
