Abstract

The invention provides a double-circulation wet filtration system for desulfurization towers for chemical production, comprising an outer circulation tower and an inner circulation tower, the inner circulation tower is arranged on the inner side of the outer circulation tower, the top is communicated with the top of the outer circulation tower, and the side of the outer circulation tower is The lower side of the wall is provided with an air intake pipe whose tail end extends to the position just below the structure of the inner circulation tower. Between the outer circulation tower and the inner circulation tower, an atomizing support plate and a rain curtain support plate are welded in sequence from top to bottom. The inner side of the tower is vertically provided with a flue gas outlet, and a spiral support plate is welded between the flue gas outlet and the inner wall of the inner circulation tower. The bottoms of the outer circulation tower and the inner circulation tower are respectively connected with the primary slurry outlet and the secondary slurry outlet. The present invention improves the efficiency of limewater slurry and the The effective contact of flue gas greatly improves the effect of flue gas desulfurization and has a good development prospect.

Description

technical field [0001] The invention relates to the field of industrial waste gas treatment, in particular to a double-circulation wet filtration system of a desulfurization tower for chemical production. Background technique [0002] With the improvement of social awareness of environmental protection and the improvement of national laws and regulations, the control of pollutant emissions from facilities has become increasingly strict, and the SO emission value of industrial waste gas is required to be lower than 50mg / NM. The wet desulfurization process has high desulfurization efficiency (≥95%), It has the advantages of good stability and low operating cost. It is widely used in the ultra-low emission desulfurization treatment of flue gas in the domestic chemical industry. In the wet desulfurization process, the limestone-gypsum wet desulfurization process is the most common. This process uses limestone slurry as the absorbent. , the flue gas is washed by limestone slurry ...
