Ammonia-containing tail gas treatment device for steam stripping ammonia distillation and use method of ammonia-containing tail gas treatment device

Abstract

The invention discloses an ammonia-containing tail gas treatment device for steam stripping ammonia distillation and a use method thereof.The ammonia-containing tail gas treatment device comprises a treatment tank, supporting rods are fixedly connected to the two ends of the bottom of the inner wall of the treatment tank, an annular pipe is fixedly connected between the tops of the two supporting rods, and gas outlet pipes are fixedly connected to the top of the annular pipe at equal intervals; a suction fan is fixedly mounted on one side of the bottom of the treatment tank, the output end of the suction fan extends into the treatment tank and is fixedly connected with one end of an annular pipe, and a rotating rod is rotationally connected to the position, located above the annular pipe, in the treatment tank. The ammonia-containing tail gas treatment device has the advantages that ammonia-containing tail gas is uniformly introduced into the treatment tank by the aid of the annular pipe and is buffered and decelerated by the aid of the blades, accordingly, the ammonia-containing tail gas can stay in the treatment tank for a longer time, treatment effects can be further improved by spraying the ammonia-containing tail gas, and the ammonia-containing tail gas treatment device is favorable for actual application and operation.

Description

technical field [0001] The invention belongs to the technical field of tail gas treatment, and in particular relates to an ammonia-containing tail gas treatment device for stripping and distilling ammonia and a use method thereof. Background technique [0002] In the existing life, with the rapid development of industries such as chemical industry, metallurgy and new materials, a large amount of ammonia nitrogen wastewater is discharged into nature, causing social problems such as eutrophication of water bodies, black and smelly water quality, and reduced service life of water supply systems. In particular, high-concentration ammonia nitrogen wastewater (NHs-N>≥>500mg / L) is easily transformed into nitrosamines with strong carcinogenic, strong teratogenic and strong mutagenic effects, which are extremely harmful to humans and organisms. Most of the wastewater is high-concentration ammonia-nitrogen wastewater. High-concentration ammonia-nitrogen wastewater has problems s...

Problems solved by technology

[0003] However, when the existing ammonia-containing tail gas treatment devices for stripping and distilling ammonia are used, most of them are passed into the aqueous solution for purification treatment, and then filtered with activated carbon, and the ammonia-containing tail gas is generally passed through The suction fan is sucked into the tail gas treatment equipment, so the moving rate of the ammonia-containing tail gas is high, which leads to poor filtering effect and cannot achieve the expected treatment effect, which is not conducive to actual application and operation
