Equipment for removing nano-grade dust in gas and dust removing method of equipment

Abstract

The invention relates to equipment for removing nano-grade dust in gas and a dust removing method of the equipment. According to the dust removing equipment, a separation force is directly applied to particles so that the nano-grade dust in the gas can be removed; and the dust removing equipment is suitable for optical communication and new energy source industries. The dust removing equipment comprises a plate type positive electrode, a pipe type negative electrode, a spraying device, a gas flow distribution device, a shell, a buffering groove, an exhausting pipe and a draught fan; a plate type positive electrode mounting bracket and a pipe type negative electrode mounting bracket are mounted in the shell; the plate type positive electrode is mounted on the plate type positive electrode mounting bracket; the pipe type negative electrode is mounted on the pipe type negative electrode mounting bracket; the pipe type negative electrode is located in the middle of the plate type positive electrode; the spraying device comprises water pipes and spraying heads; the water pipes are distributed at the upper, middle and lower parts in the shell; the spraying heads are uniformly distributed on the water pipes and the spraying heads are distributed in a 360-degree direction; the gas flow distribution device is composed of a gradually-expanded pipe and a gas flow distribution plate; the buffering groove is formed in the lower part of the shell; and the exhausting pipe is mounted at the top of the shell and the draught fan is mounted on the exhausting pipe.

Description

technical field [0001] The invention relates to a device for removing nano-scale dust and a dust-removing method thereof. The dust-removing device directly acts separation force on particles to remove nano-scale dust in gas, and is suitable for dust removal in optical communication and new energy industries. Background technique [0002] The existing main dust removal equipment includes mechanical dust collector, filter dust collector, electric dust collector and wet dust collector. During the use of ordinary electrostatic precipitators, a large amount of dust will adhere to the positive electrode. When dealing with a large amount of exhaust gas (handling air volume ≥ 20×10 4 m 3 / h), the barrel-shaped structure, the positive electrode of ordinary materials will be corroded or deformed, once the positive and negative electrodes are deformed, frequent discharges will occur between the positive and negative electrodes, the negative electrode will swing, and the deformation o...
