Efficient condensing horizontal film wet dust removal system

Abstract

The invention discloses an efficient condensation transverse film wet type dust collection system which comprises a shell with an upper part connected with an outlet flue of a desulfurizing tower, a smoke flow averaging device mounted at the upper part in the shell, a smoke condenser which is positioned below the smoke flow averaging device and is mounted in the shell, a plurality of layers of transverse film plate fog and dust removers which are positioned below the smoke condenser and are mounted in the shell, a plurality of flushing devices mounted on each layer of transverse film plate fog and dust remover, a liquid collection guide pipe mounted in the center of each transverse film plate fog and dust remover, and a smoke exhaust pipeline mounted on the lower side face of the shell. The efficient condensation transverse film wet type dust collection system disclosed by the invention is high in dust collection efficiency, low in investment and operation cost and saved in energy, and can purify smoke and discharge clean smoke. The efficient condensation transverse film wet type dust collection system can be widely applied to purification of smoke of coal-fired boilers in power stations.

Description

technical field [0001] The invention relates to a high-efficiency condensing horizontal film wet dust removal system, which can be widely used in the purification treatment of flue gas from coal-fired boilers in power stations. Background technique [0002] The environmental problems caused by air pollution are becoming more and more serious, and the control of air pollutants has become the consensus of the whole society. The dust emission of coal-fired boilers is one of the main causes of air pollution. [0003] At present, the existing wet electrostatic precipitator is arranged at the front of the desulfurization system. Due to the influence of dust removal efficiency, dust secondary flying and desulfurization tower slurry carrying factors, its emission is difficult to meet the ultra-low emission requirements; and all rely on electric field force The function is to collect dust, the investment is large, and the operating cost is high.
