Industrial tail gas high-efficiency desulfurizer and preparation method thereof

Abstract

The invention discloses an industrial tail gas high-efficiency desulfurizer and a preparation method thereof, the industrial tail gas high-efficiency desulfurizer comprises the following raw materials: a common sodium bicarbonate product as a raw material, a sodium bicarbonate product and an anti-blocking agent with feldspar minerals as main components, the addition proportion is 0.5-40%. The feldspar mineral product comprises orthoclase, albite, anorthite, celsian, celsian, microcline, sanidine and all minerals with the feldspar as the main component, the feldspar mineral product can be independently used as an anti-blocking agent, and the addition proportion of the feldspar is 0.5% or above when the feldspar mineral product is independently used. According to the industrial tail gas high-efficiency desulfurizer and the preparation method thereof, sodium bicarbonate has obvious advantages in keeping the dispersibility of a product in a long-term storage process and preventing caking performance, is low in cost, is easily accepted by the market, has very strong generalization performance, and is worthy of popularization. The method has the characteristics of high acid gas removal efficiency, low consumption, low comprehensive cost and the like, and brings better use prospects.

Description

technical field

[0001] The invention relates to the field of tail gas treatment, in particular to a high-efficiency desulfurizer for industrial tail gas and a preparation method thereof. Background technique

[0002] Exhaust gas from industries such as iron and steel, coking, cement, coal-fired power generation, refractory material production, and waste incineration has become one of the major problems in urban economic development. How to control exhaust emissions has also attracted widespread attention. The composition is extremely complex, and the main pollutants are smoke, acid gas, etc. At present, most of the domestic use semi-dry method to treat the acid gas in the tail gas. The removal of acid gas is not complete and cannot meet higher standards of emission requirements. Sodium bicarbonate can be used to solve the above-mentioned acid gas treatment in industrial tail gas, which has a better treatment effect than hydrated lime. With the continuous development of scien...
