Abstract
The utility model relates to a double spiral-flow water-film desulfuring-dusting tower, which is provided with a tower body (1); a smoke inlet (2), a smoke outlet (4) and a waste liquid overflow port (3) are arranged on the tower body (1); a demister is arranged on the upper part in the tower body (1). The utility model is characterized in that a spiral lifting type liquid inlet pipe (6) is wound on the outer wall of the middle part of the tower body (1); a nozzle (7) extending into the tower body (1) is arranged on the liquid inlet pipe (6). The defroster is a combined cylinder type defroster; the spiral lifting type flow guiding plate (8) is arranged between the cylinders (5) of the combined cylinder. The utility model has the advantages that the size is small, the cost is small, the contact of gas and liquid is good, the forming of channeling can be avoided, and the effects on collecting harmful gas, smoke dust and mist are good.
Description
The utility model relates to a kind of device of Purge gas, particularly relates to a kind of bispin flowing water film desulfurization and dedusting tower.
In order to remove normal granite with water film tower and the spray column of adopting such as sulphur-containing substance, flue dust and mist in the gas, air inlet, inlet, gas outlet and liquid outlet are arranged all on both tower bodies at present, the tower body internal upper part is equipped with demister.In the granite with water film tower, form the cleaning solution liquid film on the tower body inwall, the latter contacts with gas, can remove wherein contained pollutant.Gas contacts with the droplet of cleaning solution in the spray column tower body.The common drawback of these towers is that gas-liquid can not fully contact, and the efficient of therefore removing pollutant and flue dust is lower.
The purpose of this utility model provides a kind of bispin flowing water film desulfurization and dedusting tower, and it can overcome the above-mentioned shortcoming of existing apparatus.
The utility model has a tower body, and air inlet, gas outlet, waste liquid overfall are arranged on the tower body, at the tower body internal upper part demister is housed, and it is characterized in that installing around on the outer wall of tower body middle part the feed tube of spiral ascending manner, has nozzle to extend in the tower body on this feed tube.
The utility model volume is little, and low price can make gas-liquid contact, and avoids forming channel, removes the effective of pernicious gas, flue dust and mist.
Below by embodiment and description of drawings the utility model.
Accompanying drawing is a structural representation of the present utility model.
The utility model has a tower body (1), air inlet (2) and waste liquid overfall (3) are arranged at tower body (1) bottom, gas outlet (4) is arranged at the top, at tower body (1) internal upper part demister is housed, on the outer wall of tower body (1) middle part, installing around spiral ascending manner feed tube (6), have on this feed tube (6) 4 groups totally 12 nozzles (7) extend in the tower body (1), the cleaning solution that can absorb sulfide in the gas, dust is entered by the port of feed tube (6), and in each nozzle (7) sprays into tower body (1).The middle part that 4 groups of water curtain type nozzles (7) relatively are evenly distributed in the tower wall from top to bottom by 4 directions in front, rear, left and right respectively is shape in the shape of a spiral, the cleaning solution of their ejections is vaporific whereabouts, also formed the moisture film that descends along the inwall of tower simultaneously, cleaning solution is fully contacted with the gas that is entered by air inlet (2).Described demister is multiple tube demister, is forming the deflector (8) that the spiral ascending manner is housed between the tube (5) of multiple tube.Under the mandatory guidance of spiral deflector (8), can produce the air-flow of rotation, water smoke under the effect of rotary centrifugal force in the gas and grit collide on the inside and outside barrel of tube (5), form the bottom that big drop splashes into tower body (1), flow out through waste liquid overfall (3).The gas of dry purification is (4) discharge from the gas outlet.When using the utility model, this gas outlet (4) are communicated with air-introduced machine or chimney.
Claims (2)
1. bispin flowing water film desulfurization and dedusting tower, one tower body (1) is arranged, air inlet (2), gas outlet (4), waste liquid overfall (3) are arranged on the tower body (1), at tower body (1) internal upper part demister is housed, it is characterized in that on the outer wall of tower body (1) middle part, installing around the feed tube (6) of spiral ascending manner, have nozzle (7) to extend in the tower body (1) on this feed tube (6).
2. desulfurization and dedusting tower as claimed in claim 1 is characterized in that described demister is multiple tube demister, is forming the deflector (8) that the spiral ascending manner is housed between the tube (5) of multiple tube.
