Underspin cyclone dust collector and flue gas atomization desulfuration equipment

Abstract

The invention discloses an underspin cyclone dust collector and flue gas atomization desulfuration equipment. The underspin cyclone dust collector comprises a tank body, an air inlet pipe and an air outlet pipe, wherein the tank body comprises a cylinder part and a circular table part; a side of an inner side wall of the air inlet pipe, parallel to a central axis of the air inlet pipe, is tangent with a cross section of the air outlet pipe; and a side of an outer side wall opposite to the inner side wall of the air inlet pipe, parallel to the central axis of the air inlet pipe, is tangent with a bottom surface of the cylinder part. According to the flue gas atomization desulfuration equipment, a first dust collector, a second dust collector, a third dust collector and a fourth dust collector that are the underspin cyclone dust collectors. Compared with the cyclone dust collector in the prior art, a dust collection effect of the underspin cyclone dust collector is better, the underspin cyclone dust collector is particularly applicable to higher dust content in gas, the dust collection capacity of the flue gas atomization desulfuration equipment is improved, purifying and dust collection effects of the flue gas atomization desulfuration equipment are improved further, and secondary dust collection can be conducted.

Description

technical field [0001] The invention relates to a specially designed device for purifying waste gas, in particular to a downcycling cyclone dust collector and flue gas atomization desulfurization device. Background technique [0002] The cyclone dust collector is a dust removal equipment that uses the accelerated rotation of the gas to generate centrifugal force to separate the rotating solid dust from the gas. It is widely used in various industrial boilers, mechanical processing, metallurgical building materials, casting, mining, cement, mining and other industries. . [0003] In recent years, cyclone dust collectors have been widely used in the purification and treatment of flue gas produced by boilers. The cyclone dust collector usually includes a tank body, an air inlet pipe extending into the tank body and communicating with the tank body, an air outlet pipe drawn from the tank body, and a collecting device arranged at the lower part of the tank body. The tank body u...

Problems solved by technology

[0004] Although the cyclone dust collector with the above structure and the flue gas atomization desulfurization equipment using the above cyclone dust collector are widely used in the field of industrial gas dust removal, practice has shown that when the dust content in the gas entering the air inlet pipe is high, the cyclone The dust collector cannot complete the dust removal task well; and the traditional flue gas atomization desulfurization equipment using the above-mentioned cyclone dust collector cannot fully atomize the flue gas rich in sulfide, so that the desulfurization effect is poor
