Electric dust removal device for dead burnt magnesia kiln

Abstract

The electric dust removal device comprises a dust removal assembly, a flushing assembly, a supporting frame and a dust discharging hopper, a dust inlet is formed in the front end of the dust removal assembly, an air outlet is formed in the rear end of the dust removal assembly, and the top of the dust removal assembly and the bottom of the flushing assembly are fixedly installed; the bottom of the dust removal assembly and the top of the dust discharging hopper are fixedly installed. According to the electric dust removal device for the dead burnt magnesia kiln, when dust adheres to the surface of a positive plate, an eccentric wheel in a groove rotates due to the fact that air flow continuously blows fan blades, and after the eccentric wheel transmits vibration to a limiting ring in the rapid rotating process, the limiting ring continuously impacts a protruding block in the groove, so that the dust is removed; and therefore, the positive plate continuously vibrates at high frequency in an electric field, and dust adhered to the surface is shaken off into a dust discharging hopper at the bottom.

Description

technical field [0001] The invention relates to the field of electric dust removal devices, and more specifically, relates to an electric dust removal device for a dead-burned magnesia kiln. Background technique [0002] Dead-burned magnesia belongs to sintered magnesia, which is the main raw material for producing ordinary magnesia fired bricks and unshaped refractory materials. The production equipment of dead burnt magnesia in my country is mostly hard kiln, which uses massive magnesite ore as raw material and coke as fuel, adopts one-step calcination process and manual discharge method, and the MgO mass fraction of dead burnt magnesia produced in this way is 92 %. However, this process has defects such as low ore utilization rate, low product purity and density, poor continuous operation degree, and serious environmental pollution. Therefore, it is necessary to install an exhaust gas dust removal device to purify the exhaust gas during the processing of dead-burned magne...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the anode plate in the prior art that has been used in the environment for a long time in dust, due to the effect of ambient water vapor or scouring water in the air, the dust will be seriously bonded to the surface of the anode plate, resulting in electrical conductivity between the anode plate and the cathode plate. The effect is weakened, so that the dust in the exhaust gas cannot be electrically separated in the electrostatic field. After the dust particles and negative ions are not combined with negative charges, they will not be able to discharge and deposit on the surface of the anode, which will seriously affect the dust removal effect. The present invention proposes a An electric precipitator for a dead-burned magnesia kiln, which can improve the efficiency of dust removal
