A wet dust collector

Abstract

The invention provides a wet dust collector which comprises a gas inlet pipe, a gas flow deflector, an annular agitation groove, a sludge diversion trench, a circular platform shield, a liquid blockage gate, a gas inlet pipe, a blower, a sludge-collecting hopper, a sludge discharge valve, a liquid inlet pipe, an overflow box, a communicating pipe and a support plate. Dusty gas is uniformly distributed to the annular agitation groove by virtue of the gas flow deflector; the circular platform shield inhibits splashing of a liquid, thereby being conductive to full contact of dust particles and liquid; the liquid in the gas flow is recycled through the liquid blockage gate; clean gas is discharged through a gas discharge pipe; the blower generates negative pressure for the device; the sludge-collecting hopper is beneficial to convergence and concentration of sludge; the sludge in the sludge-collecting hopper is discharged through the sludge discharge valve; the liquid is added by virtue of the liquid inlet pipe, so as to keep the quantity balance of a liquid in the dust collector; the overflow box achieves an effect of stabilizing a liquid surface; the communicating pipe balances the pressures of liquid surfaces in the overflow box and a dust chamber; and the support plate is used for fixedly connecting an inner ring and an outer ring of the annular agitation groove. The dust collecting device provided by the invention has the characteristics of high dedusting efficiency, high handling capacity and the like, and is applicable to removal operations for various types of dust.

Description

technical field [0001] The invention relates to a wet dust collector, which is especially suitable for dust removal operations in industries such as mining, construction, energy and agriculture, and is also suitable for cooling coal-fired boiler flue gas and removing harmful gas components. Background technique [0002] Due to its small particle size, dust is easily inhaled by the human body. People who have been in the dust environment for a long time have a high probability of suffering from pneumoconiosis, which seriously affects the occupational health level and affects the physical and mental health of workers. At the same time, the work with serious dust pollution In the environment, the operating conditions of instruments and equipment deteriorate and wear increases, resulting in shortened service life of equipment and increased maintenance costs; dust diffusion is also an important aspect of air pollution. Dust control is an important way to promote clean production,...
