Abstract

The invention belongs to the fields of desulfurization and denitrification, and in particular relates to a large-particle crystallization device of an ammonia process desulfurization and denitration system and a using method of the device. The invention provides the following solution aiming at the problem that current inflow gas not filtered: the device comprises a tower body, the interior of thetower body is provided with an oxidation section, a concentration section, an absorption section, a purifying water washing section and a demisting section, a demister is arranged in the demisting section, one side of the tower body is provided with a filter box, a same gas inlet pipe is fixedly installed at sides, close to each other, of the filter box and the tower body, two ends of the gas inlet pipe respectively communicate with the filter box and the tower body, and a filter net is fixedly installed in the filter box. The device provided by the invention has a simple structure; and on the basis of increasing crystal grain growth time through the demister, allowing the crystal grain to grow, making crystalline particles larger and increasing economic benefits, the device can effectively filter out impurities in the air through the arranged filter net, thereby guaranteeing the product quality; and meanwhile the filter net can be continuously cleaned, so that smooth gas inflow of the tower body is guaranteed.

Description

technical field [0001] The invention relates to the technical field of desulfurization and denitrification, in particular to a large particle crystallization device of an ammonia desulfurization and denitrification system and a method for using the same. Background technique [0002] The integrated technology of desulfurization and denitrification widely used at home and abroad today is mainly the combination of wet flue gas desulfurization and selective catalytic reduction or selective non-catalytic reduction technology denitrification. The wet flue gas desulfurization is commonly used by the calcium method using lime or limestone, and the desulfurization efficiency can be reduced. Up to 90%, its disadvantage is that the project is huge, the initial investment and operation costs are high, and it is easy to form secondary pollution. [0003] The publication number is CN105749716B, which discloses a desulfurization and denitrification method for a desulfurization and denitri...
