Problems solved by technology

In addition, the exhausted flue gas is still a saturated gas higher than the ambient temperature. If the humidity is too high, it will condense immediately after leaving the chimney mouth, causing the so-called serious tailing phenomenon of the chimney.

Abstract

The invention relates to a wet process desulphurization dust removal device, which comprises a comprehensive tower, a heat exchanger mounted at the top end of the comprehensive tower, a reverse spraypipe connected with the heat exchanger and the comprehensive tower and arranged in a communicating manner, a rapid solid-liquid separator matched with the comprehensive tower for use, an air cooling calandria matched with the rapid solid-liquid separator for use, and a cooling tower matched with the air cooling calandria for use. According to the invention, the device is reasonable in structure and good in using effect, integrates flue gas purification, desulfurization, dust removal, water control and smoke abatement, and achieves high-efficiency desulfurization and dust removal, the emissionindex of the device can completely meet and exceed the ultra-clean emission requirement implemented at present, water resources used for smoke control can be recovered so as to recycle the water resource, the huge condition of flue gas desulfurization and dust removal equipment is changed, the occupied area is small, the equipment capital investment is reduced, energy-saving operation can be achieved, the cost is saved, and popularization is worth.

Description

technical field [0001] The invention relates to the technical field of exhaust gas desulfurization and dust removal, in particular to a wet desulfurization and dust removal device and a method for using the same. Background technique [0002] At present, for the purification treatment of flue gas desulfurization and dust removal, most of them adopt wet process. Wet desulfurization is characterized in that the desulfurization system is located at the end of the flue and behind the comprehensive tower. The flue gas needs to be reheated before it can be discharged. The purification process is to wash and purify the high-temperature flue gas with detergent and then discharge it. The discharged flue gas will be a saturated gas with water foam. The spray of the gas still contains harmful substances such as dust nuclei, aerosols and soluble salts. In addition, the exhausted flue gas is still a saturated gas higher than the ambient temperature. If the humidity is too high, it will ...
