Novel ammonia water evaporator

Abstract

The invention relates to an ammonia water evaporator, in particular to a novel ammonia water evaporator. The novel ammonia water evaporator comprises an outlet flange, an outlet variable diameter section, an evaporator body, an ammonia water spray gun opening, a uniform distribution plate, an inlet variable diameter section and an inlet flange, wherein the outlet variable diameter section is arranged above the evaporator body; the outlet flange is mounted at the top of the outlet variable diameter section; the inlet variable diameter section is arranged below the evaporator body; the inlet flange is mounted at the bottom of the inlet variable diameter section; the ammonia water spray gun opening is formed in the side surface, close to the inlet variable diameter section, of the lower partof the evaporator body; the uniform distribution plate is fixedly mounted on the inner wall of the evaporator body; and the vertical mounting height of the uniform distribution plate is lower than a vertical height of the ammonia water spray gun opening. The novel ammonia water evaporator is specially designed, is capable of ensuring the uniform distribution of flue gas, and plays a key role in the evaporation of ammonia water and the uniform mixing of ammonia and flue gas after the evaporation.

Description

technical field [0001] The invention relates to an ammonia water evaporator, in particular to a novel ammonia water evaporator. Background technique [0002] The current ammonia water evaporator has a simple structure. The ammonia water is sprayed into the evaporator through a spray gun, evaporated by high-temperature flue gas, and transported to the denitration reaction area through the outlet pipeline. But there are two disadvantages: 1. The mixing uniformity of evaporated ammonia gas and flue gas cannot be guaranteed; 2. Maintenance and installation are complicated. In the prior art, some people solve the problem of uneven mixing of ammonia and flue gas by adding equipment from the downstream, but the cost of the equipment is high and the investment is large. Contents of the invention [0003] The purpose of the present invention is to provide a new type of ammonia water evaporator, which has a special structural design, simple structure, low investment, convenient and...
