Electrostatic precipitator for exhaust gas through wet process

Abstract

The invention discloses an electrostatic precipitator for exhaust gas through a wet process. The electrostatic precipitator comprises a precipitator body and further comprises an atomizing spray mechanism, a uniform direct-current high-voltage electric field mechanism and an electric control device, wherein the precipitator body comprises a precipitator housing; the atomizing spray mechanism and the uniform direct-current high-voltage electric field mechanism are arranged inside the precipitator housing; the electric control device is used for controlling the movement of the atomizing spray mechanism and the uniform direct-current high-voltage electric field mechanism; a whirlwind inlet is formed in one side of the bottom of the housing; a waste liquor outlet is formed in the other side of the bottom of the housing; an air outlet is formed in the top of the housing; a gas condenser used for cooling and condensing high-temperature gas is arranged at the position of the whirlwind inlet and used for liquefying oil in the gas; the atomizing spray mechanism is arranged above the whirlwind inlet; the uniform direct-current high-voltage electric field mechanism is arranged above the atomizing spray mechanism; the atomizing spray mechanism is composed of a water curtain wall composed of a plurality of atomizing nozzles. According to the electrostatic precipitator, because the atomizing spray mechanism and the high-voltage electric field mechanism are adopted, dust collection efficiency is improved, the production cost is reduced, and the electrostatic precipitator can be widely applied to waste gas treatment of printing, dyeing and shaping machines.

Description

technical field [0001] The invention relates to a waste gas wet-process electrostatic precipitator, which belongs to the field of centralized waste gas purification treatment equipment for printing and dyeing setting machines. Background technique [0002] As people become more and more aware of environmental protection and their awareness of environmental protection continues to increase, many production-oriented enterprises have consciously increased the corresponding pollution control equipment, which has greatly reduced the resentment of residents living near the factories, and the number of complaints has also increased. The less the number, the more the Environmental Protection Agency is no longer "crowded", busy all day long. [0003] However, due to the expansion of the production capacity of the enterprise, the emission of exhaust gas has also increased accordingly, and the original exhaust gas treatment equipment is stretched. In addition, the environmental protect...
