Composite fiber denitration agent and preparation method thereof

Abstract

The invention discloses a composite fiber denitration agent and a preparation method thereof, wherein the composite fiber denitration agent comprises the following components in parts by weight: a main material, 0.1-0.5 part of an auxiliary agent, 0.1-0.2 part of a thickening agent, 1-2 parts of a dispersant, 2-5 parts of a flame retardant and 0.2-1 part of a catalyst, and the main material contains 30-70 parts of polymer organic fiber. The preparation method of the composite fiber denitration agent is used for preparing the composite fiber denitration agent. The high-molecular organic fiber is used as the main raw material of the denitration agent, in the production and denitration process, no harm is generated to the environment, the high-molecular organic fiber is easy to dissolve and does not need to be emulsified, and the production cost is low. The denitration efficiency is high, and the adaptive temperature range is large.

Description

technical field [0001] The invention relates to a composite fiber denitration agent and a preparation method thereof. Background technique [0002] NO X Appearing as a harmful gas in industrial production such as thermal power industry, ceramic glass industry, coking industry, cement industry, etc., it has great harm to the normal atmospheric environment, and it can directly cause acid rain and toxic smog. Therefore, the NO in the flue gas in the production device X There are relatively large restrictions, and out of stock is particularly important. In recent years, traditional NO removal methods used in thermal power industry, coking industry, cement industry and ceramic glass industry X The methods include selective non-catalytic reduction (SNCR), selective catalytic reduction (SCR) and other methods. These methods all require corresponding denitrification reducing agents. [0003] The choice of denitrification reducing agent is generally considered comprehensively in...

Problems solved by technology

However, the cost of using cyanuric acid and biological calcium solution is relatively high, which seriously affects the cost of denitrification

[0007] Chinese patent application number CN202010061181.4 discloses a preparation method of a composite organic calcium-based denitrification agent, which uses organic matter as the main source material. Since the organic matter is easy to stratify, emulsification and polymerization inhibitors are required, and the production cost is high.
