Embodiment Construction

[0014] The main components of converter gas dry dedusting system are converter, vaporization cooling flue, steam drum, gas-liquid two-phase spray gun, evaporative cooler, coarse ash collection system and electrostatic precipitator. The vaporization cooling flue is mainly to reduce the temperature of the gas to generate saturated water vapor, which is separated and collected by the steam drum. It is a converter gas waste heat recovery device; the evaporative cooler lowers the gas temperature by spraying water from the gas-liquid two-phase spray gun, and passes through the bottom of the evaporative cooler. The connected coarse ash collection system coarsely removes dust to the coarse ash bin and adjusts the dielectric constant of the dust, and realizes fine dust removal through the electrostatic precipitator system, etc.

[0015] As shown in Fig. 1, it is an embodiment of the electrostatic precipitator used in the converter gas dry dust removal system according to the present inv...

Abstract

The invention discloses an electrostatic dust collector used in a converter gas dry dust collection system. The electrostatic dust collector comprises an electrostatic dust collection device, anion generators and gas switching valves, wherein the anion generators are arranged at the front end of the electrostatic dust collection device and connected with the gas switching valves; and a plurality of gas flow distribution plates which are connected in series, and a plurality of horizontally parallel cathode plates and anode plates are arranged in the electrostatic dust collection device. By the electrostatic dust collector in the converter gas dry dust collection system, the phenomenon of discharge between the anode plates and the cathode plates in the electrostatic dust collection device is avoided, and the damage of large explosion to the electrostatic dust collection device is avoided, so that the safety of the dry dust collection system is improved.

Description

technical field [0001] The invention relates to an electrostatic precipitator used in a converter gas dry dedusting system. Background technique [0002] Dust removal principle of electrostatic precipitator: 60-70% of the dust in the gas is removed in the electrostatic precipitator, usually the electrostatic precipitator can treat the gas to 15mg / Nm 3 . The working process of the electrostatic precipitator is mainly divided into the following steps: [0003] A high DC voltage is applied between the polar line and the dust collecting electrode to cause corona discharge to occur on the polar line, ionize the gas, and generate a large number of free electrons and positive ions. Positive ions in the so-called corona region near the pole line are immediately attracted by the corona pole (assumed to be negatively charged) and lose their charge. The free electrons and the negative ions formed immediately move to the dust collecting pole (positive pole) due to the force of the el...
