Integrated flue gas purification system

Abstract

The invention provides an integrated flue gas purification system. The system comprises a chimney tower, a spraying device, a water scrubbing device, a mist removal device and an electric dust removaldevice, wherein the spraying device, the water scrubbing device, the mist removal device and the electric dust removal device are sequentially arranged in the chimney tower from bottom to top; the system also comprises a flue gas inlet channel and a flue gas outlet channel which are both communicated with the inner part of the chimney tower; flue gas enters into the chimney from the flue gas inlet channel, sequentially flows through the spraying device, the water scrubbing device, the mist removal device and the electric dust removal device, and then flows out of the chimney tower from the flue gas outlet channel. The integrated flue gas purification system disclosed by the invention has the following advantages that the integrated flue gas purification system adopting the structure has acompact structure and is reasonable in arrangement; by fully taking consideration of sequence steps for flue gas treatment, the purification efficiency is high, the size of produced equipment is small, the construction cost is lower, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment, in particular to an integrated flue gas purification system. Background technique [0002] At present, in some factories, a large amount of waste gas will be generated during the production process, and direct discharge into the air will bring a lot of environmental pollution, such as dust, impurities, harmful gas sulfur dioxide, etc., will cause air pollution, so before the airflow enters the air Dust removal and purification process must be carried out. [0003] In the existing flue gas purification equipment, most of them are equipped with cooling, water washing, demisting, and dust removal equipment respectively, and then connect the equipment through setting up flue gas circulation pipes, so as to realize the cooling and cooling of flue gas, water washing and desulfurization, and desulfurization. Fog drying and dust adsorption, so that the exhaust gas discharged from production a...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a new integrated system for flue gas purification, which solves the problem that most of the existing flue gas purification equipment cannot realize integrated treatment of flue gas cooling, water washing and desulfurization, demisting and drying, and dust adsorption. There is a simple integrated treatment equipment, but the structure is complex, the equipment is bulky, the flue gas purification effect is not good, and the cost is high, so it is not suitable for small factories
