The invention discloses an acid fog absorption tower, which comprises a cylindrical tower body, wherein the upper end of the tower body is connected with an exhaust pipe, the lower part of the tower body is connected with a water tank, the side wall of the tower body is connected with an air intake, the inside of the tower body is provided with a vapor-water separator, a packing layer, a guide barrel and a three-stage spray pipe form top to bottom; the water tank is communicated with the three-stage spray pipe through a connecting pipe and a circulating water pump, and the three-stage spray pipe consists of an upper spray pipe, an intermediate spray pipe, and a lower spray pipe; the upper spray pipe and the lower spray pipe are communicated with a water distributor respectively; the waterdistributor comprises a main water inlet pipe and a branch water distribution pipe communicated with the main water inlet pipe, and the branch water distribution pipe is provided with a helical sprayhead; and the guide barrel is positioned between the upper spray pipe and the intermediate spray pipe, a defrosting pan is fixedly connected between the guide barrel and the tower body, and the upperpart of the guide barrel is provided with a water retaining ring plate. The absorption tower has removal rate up to 100 percent, and has the advantages of small resistance, small energy consumption, high treatment efficiency, compact structure, corrosion resistance, aging resistance, and the like.
Description
Acid mist absorption tower technical field The invention relates to a treatment device for industrial waste acid water, in particular to an acid mist absorption tower with the function of absorbing acid mist. Background technique In industrial production plants, a large amount of acid waste liquid is often produced. Acid waste liquid is very harmful to industrial production equipment and the environment. Moreover, as my country's requirements for energy conservation and emission reduction of enterprises are getting higher and higher, the removal of acid waste liquid has become a key issue. Traditional spray towers use simple neutralization treatment methods, so the effective removal rate of acid mist is generally around 85%. The traditional absorption tower is a mother-child perforated pipe water distribution, which has the disadvantages of uneven water distribution and insufficient contact of gas and liquid. Moreover, the water distribution method is simple, and the rea...
