Semi-dry desulfurization tower with self-circulation adjusting device of flue gas

Abstract

The invention discloses a semi-dry desulfurization tower with a self-circulation adjusting device of flue gas. The tower comprises a tower body, an air outlet is arranged on the tower body, an air inlet is arranged at the bottom of the tower body, a throat cavity is arranged between the air inlet and the tower body, and self-circulation adjusting device for adjusting flue gas wind amount in the tower body is arranged on the tower body. The self-circulation adjusting device comprises the following components: a circulation wind taking pipe which is arranged on the air outlet, a circulation wind feeding pipe which is arranged on the air inlet, a circulation pipeline for communicating the circulation wind taking pipe and the circulation wind feeding pipe, a circulating fan which is arranged on the circulation pipeline, and an air quantity control system which is connected to the circulating fan and is used for controlling circulation wind amount in the self-circulation adjusting device. The semi-dry desulfurization tower has the advantages of good treatment effects, high treatment efficiency, and stable operation of equipment.

Description

technical field [0001] The invention belongs to the technical field of air pollutant treatment equipment, in particular to a semi-dry desulfurization tower equipped with a flue gas self-circulation regulating device. Background technique [0002] It is well known that sulfur dioxide (SO 2 ) not only pollutes the air, directly endangers human health and the survival of animals and plants, but also is the main substance that forms acid rain. Acid rain has caused great long-term harm to the living environment of the earth, and it has attracted great attention from all countries in the world. Combustion of fossil fuels is sulfur dioxide (SO 2 ) main source. Flue gas desulfurization technology is the human elimination of sulfur dioxide (SO 2 ) One of the main means of pollution. [0003] Flue gas desulfurization technology is divided according to the dry and wet state of desulfurization agent (also called desulfurization absorbent) and desulfurization product (also called de...

Problems solved by technology

Especially when the peak impact occurs, the processing equipment is difficult to adapt, and the processing time and space are relatively insufficient

However, expanding the capacity of processing equipment will cause disadvantages such as high investment, large floor space, and heavy operating costs.
