Description
Technical Field
The utility model relates to a waste gas treatment technical field refers in particular to a tertiary filtration spray column.
Background
The spray tower exists as a treatment device for environmental protection waste gas treatment, and is divided into a circulating water spray tower, an alkali liquor spray tower and an acid liquor spray tower (also called acid washing tower) according to the working principle.
The spray tower is divided into a glass fiber reinforced plastic spray tower, a PP spray tower and a stainless steel spray tower according to the material of the tower body. And selecting reasonable spraying materials and spraying processes according to different properties of the waste gas. When dust-containing waste gas or oil-containing waste gas passes through the spray tower body, liquid media, alkali liquor and sulfuric acid solution are sprayed out from proper positions (determined according to design) in the tower body. If the waste gas contains acidity, alkali liquor is selected for spraying to neutralize the acidity, if the waste gas contains alkalinity, sulfuric acid solution is selected for absorption, and the specific selection of the acid-base solution is determined according to the property of the waste gas and the self condition of an enterprise. The waste gas containing oil and dust without acid and alkali can be treated by spraying circulating water solution. When waste gas entered from the tower body bottom, just with spray column spun spray medium contact, contact back waste gas or greasy dirt were wrapped up by the drop of water, the drop of water of parcel pollutant collided once more, made its surface area increase and gravity increase, the drop of water of parcel pollutant then fell into the spray column bottom under the condition of gravity increase under the influence of gravity, heavier pollutant sinks to the tower body bottom, lighter pollutant then floats on circulating water surface, later stage clearance pollutant can.
At present, the spray tower is widely used in a waste gas treatment system, when dust and oil are removed by using traditional spray tower equipment in the industries of automobile soundproof cotton, hardware grinding and polishing and the like, a large amount of foreign matters (such as cotton wool, cloth wheels, hemp wheel fragments and the like) are sucked into the spray tower and are knocked down to a circulating water tank by spray water, and the foreign matters collected in the circulating water tank are all in the circulating water in a tower body, so that the cleaning is very inconvenient; if not in time clear up, the foreign matter suspension blocks up the stifled shower nozzle of pump in circulating water, makes spray column normal operation, in addition, clears up the water that the foreign matter all will drain circulation tank at every turn, and the dimension guarantor personnel need enter the body of the tower through the inspection opening and clear up the foreign matter, belongs to airtight space operation, has certain danger, and maintains the difficulty.
