Ammonia exhaust gas treatment device

Abstract

The invention discloses an ammonia exhaust gas treatment device, comprising a filter, wherein an ammonia inlet and an ammonia outlet are respectively arranged on the filter; a plurality of filter nets are distributed inside the filter; a liquid return outlet is also arranged at the bottom part of the filter; each filter net is rolled into a compact cake shape by a silk screen; and the filter is filled with the filter nets, each filter net is divided into three layers, and the thickness of each layer is 20-25cm. The ammonia exhaust gas treatment device is simple in structure and reasonable in design; the active carbon filter mode in the prior art is replaced; curing emission is reduced; environment-friendly control is facilitated; meanwhile, active carbon dust is prevented from being dragged into a compressor to affect normal operation of the equipment; the filling and processing expenses of the active carbon are saved; and the enterprise revenue is improved.

Description

technical field [0001] The invention relates to an ammonia tail gas treatment device, in particular to an ammonia tail gas treatment device filtered by a filter screen. Background technique [0002] The ammonia tail gas treatment in the prior art generally adopts the method of adding activated carbon into the filter to react. On the one hand, this method will discharge solid waste and affect the environment. On the other hand, the activated carbon dust will be entrained by the ammonia gas to the compressor. As a result, the compressor is damaged and the normal operation of the compressor is affected. At the same time, the amount of activated carbon used in this treatment method is very large, thereby increasing the production cost of the enterprise. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to solve the deficiencies in the prior art and provide an ammonia tail gas treatment device that reduces environmental pollution a...
