Electrostatic dust suppression device of belt conveyor and control method thereof

Abstract

The invention relates to an electrostatic dust suppression device of a belt conveyor. The electrostatic dust suppression device comprises a metal barrel, a circulating fan, a rapping device fixed on the metal barrel (7) and a plurality of mutually connected cathode electrodes (3) distributed on different parts in a sealed cavity, wherein the metal barrel covers the upper portion of a belt (8) and forms the sealed cavity together with a belt conveying frame (1). High voltage is applied between the cathode electrodes and the metal barrel (7) serving as an anode and used for electrostatic adsorption of raised dust. The circulating fan (5) is used for disturbing dust-containing air flow in the sealed cavity. The rapping device is used for dropping accumulated dust from the cathode electrodes (3) and the inner wall of the metal barrel (7). The cathode electrodes (3) are star-shaped. The invention also provides a method for controlling the electrostatic dust suppression device. The electrostatic dust suppression device has the advantages of being good in dust suppression effect and saving energy.

Description

technical field [0001] The invention relates to a fugitive dust purification device suitable for a belt transportation system. Background technique [0002] Belt conveyors are widely used in ore transportation, ore crushing, mineral processing, cement, thermal power generation, sintering and other industries where powder or broken materials are transported. The dust pollution in the air of the workplace is very serious when the belt conveyor with long multi-segment links is in operation. In order to solve the dust problem of belt transportation equipment, following the national air pollution control steps, on the one hand, industrial and mining enterprises use color steel plates to block the dust scene. However, on the other hand, there are a variety of belt conveyor purification equipment on the market, most of which utilize traditional measures such as airtightness and spraying, but the purification effect is not satisfactory. The dust purification effect of the existing...

However, on the other hand, there are a variety of belt conveyor purification equipment on the market, most of which use traditional measures such as airtightness and spraying, but the purification effect is not satisfactory

The dust purification effect of the existing belt conveyor system is not good, especially the dust purification treatment at the transfer point where the belt is connected to the belt is poor. In addition, the existing purification equipment consumes a lot of energy in operation, and the daily maintenance cost is large, making it difficult to achieve the purpose of energy saving
