Problems solved by technology

The advanced nature of its design idea lies in the two electrostatic precipitating processes, but the problem is that it does not let the gas pass through the drum, which loses the inertial collection effect, and is not suitable for demisting, because the high humidity of the fog The cleaning section is not disconnected from the circuit in the environment, which is prone to short circuit

Abstract

The invention discloses a rotary demister which comprises an air inlet pipe, a cathode line, a barrel body, compressed spring electrodes, a roller-structure porous medium filter layer, a support division plate, an air outlet, a spray pipe, a liquid draining tank, a throttle valve, a division plate, idler wheels and a gear mechanism, wherein the inner wall of the barrel body is provided with a plurality of idler wheels, and the idler wheels make contact with the roller-structure porous medium filter layer; the roller-structure porous medium filter layer is connected with the gear mechanism and is supported through the support division plate; an opening is formed in the side wall of the barrel body and is connected with the air inlet pipe, and the upper end point and the lower end point of the opening of the barrel body are provided with the compressed spring electrodes which make contact with the roller-structure porous medium filter layer; the cathode line is arranged on the air inlet pipe, and the cathode line, the compressed spring electrodes and the roller-structure porous medium filter layer form a circuit. The rotary demister demists through inertial impaction of fogdrop and adsorption synergy of electric field force and can continuously demists and cleans.

Description

technical field [0001] The invention relates to environmental protection equipment in industries such as energy, environmental protection, chemical industry, pharmaceuticals, and building materials, and in particular to a rotary demister. Demister is suitable for occasions where there are fog droplets in the air flow and gas-liquid separation is required. Background technique [0002] Background of fog removal In today's society, environmental problems are becoming more and more serious with the process of industrialization, especially the atmospheric problem. Recently, PM in the atmosphere 2.5 The increase in the content is the main reason for the frequent occurrence of smog, and the fog droplets in the exhaust gas are an important incentive. Taking desulfurization as an example, the flue gas produced in the process of thermal power generation carries a large number of mist droplets, and the salt and dust in the mist droplets combine to form PM 2.5 nuclei, while water va...
