Description
Technical field
The present invention relates to a kind of wet scrubber, mainly can be used for the high concentration flue gas ash removal of various industrial furnaces and the dedusting of industrial dust.
Background technology
Industrial dedusting mainly contains dry dust removal and wet dust removal two big classes, wherein dry dust removal mainly comprises dust settling pocket technique and electrostatic precipitation technology, wet dust removal mainly is spray woods tower, foaming tower, Venturi tube, impact or self-excitation dedusting technology or the like, various technology all have many advantages separately, but its deficiency is still more outstanding, wherein the major defect of dry dust removal is that investment is big, operating cost is high, floor space is big, and wet dust removal is subjected to the restriction of dust characteristic, under the dust condition that adapts to, then should pay attention to problems such as efficiency of dust collection, service life and water consumption.
Summary of the invention
For overcoming the defective of prior art, the invention provides a kind of wet scrubber, this wet scrubber is longer relatively required small investment, efficiency of dust collection height, service life, and water consumption is less, and operating cost is low.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of wet scrubber, comprise Venturi tube and cylindric washer, the gas outlet of described Venturi tube connects the air inlet of described cylindric washer, described Venturi tube is by contraction section, larynx section and diffuser constitute, described larynx section sidewall is provided with some through holes, the outside of described through hole connects the pressure water supply pipe, the port of described diffuser constitutes the gas outlet of described Venturi tube, the port of described contraction section constitutes the air inlet of described Venturi tube, be provided with the plurality of nozzles that distributes on some cross sections respectively in the described cylindric washer, and be provided with several layers dehydration silk screen.
Operation principle of the present invention and beneficial effect are: processed gas such as flue gas enters Venturi tube by pipeline from the contraction section port of Venturi tube, dwindle because of caliber during through the larynx section, it is big that flow velocity becomes, form certain suction static pressure, described high service pipe connects cleaning solution, cooperate suction function cleaning solution to be squeezed into the larynx section of Venturi tube by pump, gas is involved in cleaning solution in the air-flow, fully mix with gas, make the dust in the gas enter cleaning solution, air-flow comes out to enter cylindric washer from diffuser, the cleaning solution water smoke of shower nozzle ejection continues same airflow collision, play further dedusting effect, simultaneously since in cylindric washer speed descend, the water smoke in the air-flow collides with silk screen during through silk screen, on silk screen, realized gas-liquid separation thus, the air-flow after the separation is substantially free of dust and other impurity, has realized the dedusting purpose thus.Venturi tube is combined with the cylindric washer that is beneficial to gas-liquid separation efficiently because the present invention has adopted, and has guaranteed efficiency of dust collection and gas-liquid separation effect, the efficiency of dust collection height; Owing to adopt the mode of high service in the larynx section of Venturi tube; overcome the little defective of amount of liquor that following negative pressure that forms by high velocity air of prior art absorbs; enough liquid-gas ratios have been guaranteed; improved efficiency of dust collection thus; simultaneously owing to the water yield that enters the larynx section under the high pressure is big; on larynx section sidewall, form water membrane, the larynx section sidewall of serious wear has been played good protective action, help improving service life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Referring to Fig. 1, a kind of wet scrubber, comprise Venturi tube and cylindric washer, the gas outlet of described Venturi tube connects the air inlet of described cylindric washer, described Venturi tube is made of contraction section 11, larynx section 12 and diffuser 13, described larynx section sidewall is provided with some through holes 14, the outside of described through hole connects pressure water supply pipe 15, the port of described diffuser constitutes the gas outlet of described Venturi tube, the port of described contraction section constitutes the air inlet of described Venturi tube, be provided with distribution plurality of nozzles 25 on some cross sections respectively in the described cylindric washer, and be provided with several layers dehydration silk screen 26.
The contraction section of described Venturi tube, larynx section and diffuser are one, mutual connection can be welding, also can be that flange connects, can also be one-body molded, described larynx section adopts the rectangular tube of sizing usually, and described through hole is opened on two relative in larynx section wall sidewalls usually, also can open on four sidewalls, its position should be distributed in whole larynx section or be distributed in more than half larynx section, so that form moisture film on whole larynx section sidewall from the position that larynx section and contraction section join.
The outside that described larynx section is distributed with through hole can be provided with the closure casing that the through hole on this sidewall is surrounded, described housing is connected with inlet channel, this inlet channel is provided with water pump, so that supply water to the housing internal pressure, by such housing is set, not only make to through hole water supply to become easily, but also can form certain static pressure, guarantee that the pressure of supply water of each through hole is equal substantially.
In the practice, described larynx section can have two relative sidewalls and relative two rectangular tank of being clipped between these two sidewalls constitute, and the sidewall of described rectangular tank inboard has constituted the sidewall of described larynx section, has described through hole on this sidewall.
Described cylindric washer takes the shape of the letter U, its air inlet pipe 21 adopts the structure of horizontal tangential air inlet, be installed on the barrel of a side 22 of U-shaped structure, its escape pipe 23 is installed in the top of barrel of the opposite side 24 of U-shaped structure, extend upward, the air-flow that enters cylindric washer from Venturi tube can form eddy flow in the air inlet pipe side neck chamber of cylindric washer thus, with further raising gas-liquid mixed ability, this eddy flow fades away through a segment distance and through behind the described dehydration silk screen, form stable air-flow in another side neck chamber of cylindric washer, so that gas-liquid separation.The bottom camber of described cylindric washer, air-flow be at cylindric washer bottom conversion direction, helps thus coming out water droplet is centrifugal.
