Problems solved by technology

The cyclone separator can only remove coarse dust particles in the flue gas, and the dust removal efficiency of wet spray dust removal and electric dust removal is not high, and the residual particle concentration of the purified gas is 100mg / m3 3 and 10mg / m 3 , and both need to consume a lot of water, and the sensible heat of the high-temperature flue gas cannot be utilized

Abstract

The invention relates to a multi-pipe type high-temperature electromagnetic floating-bed dust remover, and aims to provide the dust remover for removing dust in flue gas in high-temperature, high-pressure and high-corrosion occasions; the dust remover disclosed by the invention comprises a dust remover main body; the dust remover main body comprises an upper cylinder, an intermediate cylinder and a lower cylinder; a multi-pipe type floating-bed layer is arranged in the intermediate cylinder; an electromagnetic coil is arranged outside; the electromagnetic coil is connected to a direct-current power supply; the pipes of the multi-pipe type floating-bed layer are filled with magnetic particles; a gas inlet is arranged on the side wall of the lower cylinder; a filter material regeneration tank is arranged at the bottom; an automatic sluice valve plate is arranged between the lower cylinder and the filter material regeneration tank; a waste slurry outlet is arranged at the bottom of the filter material regeneration tank; a spiral conveyor is connected to the side wall of the filter material regeneration tank; a mechanical lifting bucket is connected to the other end of the spiral conveyor; the mechanical lifting bucket is connected to a particle distributor; the particle distributor is in the upper cylinder; and a gas outlet is connected to the side wall of the upper cylinder.

Description

technical field [0001] The invention relates to the field of energy saving and environmental protection, in particular to a multi-tube high-temperature electromagnetic floating bed dust collector, which is used for dust removal of high-temperature industrial gases. Background technique [0002] In chemical industry, petroleum, smelting, electric power and other industries, high temperature flue gas is often produced. Such as high-temperature reaction gases in petrochemical and chemical industries, high-temperature gas from blast furnaces and converters in metallurgical industries, high-temperature exhaust gases in the glass industry, high-temperature exhaust gases from boilers and incinerators, etc. In particular, the energy required by my country's heavy industry is mainly coal, and the high-temperature dust-laden exhaust gas produced after coal combustion is the main air pollutant. In recent years, my country's environmental protection requirements have become increasingl...
