Automatic equipment capable of directly adding SNCR denitration agent and preparation method of SNCR denitration agent

Abstract

The invention discloses automatic equipment capable of directly adding an SNCR (Selective Non-Catalytic Reduction) denitration agent and a preparation method of the SNCR denitration agent. The automatic equipment is characterized by comprising a belt-type conveyor, wherein the discharging end of the belt-type conveyor is connected to an inlet of a bag breaking machine; a discharging hole of the bag breaking machine is connected to a charging hole of a spiral conveyor; a discharging hole of the spiral conveyor is connected to a charging hole of a bucket-type elevator; a discharging hole of the bucket-type elevator is connected to an inlet of a urea bin; an outlet of the urea bin is connected to an inlet of a measuring bin; an outlet of the measuring bin is connected to a material inlet of a batching basin; a water inlet and a material liquid outlet are formed in the batching basin. According to the automatic equipment, bagged urea can be directly added into a urea stacking room, and a urea solution serving as the SNCR denitration agent is obtained in a urea batching room, so that the process layout is flexible, the labor intensity of workers is low, the accuracy of batching concentration is high, and the labor productivity is improved.

Description

technical field [0001] The invention relates to processing equipment for SNCR denitration agent and a method for preparing SNCR denitration agent by using the processing equipment. Background technique [0002] Facing the increasingly severe environmental protection situation, the national policy has increasingly stringent requirements on NOx emissions from power generation enterprises. SNCR denitrification technology is a mature NOx control treatment technology. The specific method is that when the temperature of the flue gas is 870-1200°C, the SNCR denitration agent (usually ammonia or urea solution) is sprayed into the flue gas to reduce NOx to generate nitrogen and water. [0003] Recently, the SNCR denitration agent generally uses urea solution, and its preparation mainly has the following two processes: [0004] (1) Dosing by manual feeding of urea granules [0005] The bagged urea in the urea stacking room is transported to the urea batching room by manual transpor...

Problems solved by technology

However, at present, the urea produced by various domestic chemical fertilizer factories is in the form of bags. Urea is a chemical that is very easy to absorb moisture. After absorbing moisture, the solution will agglomerate, which will affect the use effect.

At present, there is no tank truck specially used to transport bulk urea in China, so it cannot solve the problem of moisture absorption during urea transportation
