Control system and control method for wet-type electrostatic dust collector of coal conveying system

Abstract

The invention relates to a control system and a control method for a wet-type electrostatic dust collector of a coal conveying system. Existing electrostatic dust collectors mostly adopt a one-supporting-one design on site, that is, a set of complete dust collector control system is only used by one belt, and meanwhile, a traditional wet type electrostatic dust collector can only meet the requirement for on-site dust suppression and cannot feed back on-site conditions in the first time. The control system for the wet type electrostatic dust collector of the coal conveying system comprises a dust collector (26), an induced draft fan (23), a belt air suction cover A (24) and a belt air suction cover B (25), wherein the belt air suction cover A is connected with an A-path belt drawer type filter (1), the belt air suction cover B is connected with a B-path belt drawer type filter (2), the A-path belt drawer type filter is connected with an A-path belt electric butterfly valve (3), and the B-path belt drawer type filter is connected with a B-path belt electric butterfly valve (4). The system and the method are applied to the electrostatic dust collector.

Description

[0001] The invention relates to a control system and a control method of a wet electrostatic precipitator in a coal conveying system. Background technique: [0002] With the increasing requirements for environmental protection, energy-saving production, and safety and reliability, higher requirements are put forward for field equipment. The transmission of raw coal must not only cause no pollution to the environment, but also be safe and reliable. Most of the existing electrostatic precipitators on site adopt a one-to-one design, that is, a complete set of precipitator control system is only used for one belt. Although this design can achieve zero dust in raw coal transportation, environmental protection and high efficiency, but for coal-fired units that use multiple belts for raw coal transportation, two or three sets of dust collector systems will actually be put into operation in one transfer station. At the same time, the traditional wet electrostatic precipitator needs t...

This will invisibly increase the workload in terms of equipment maintenance, and the actual available area on site will also be invisibly occupied

[0003] Moreover, during the entire raw coal transmission process of the existing electrostatic precipitator, the temperature changes in the coal guide trough and the coal falling barrel area in the transfer station are still monitoring blind spots. This area is often a fire-prone area, and it is difficult to detect when a disaster occurs.

The original wet electrostatic precipitator can only meet the needs of on-site dust suppression. There is no real-time monitoring and feedback of temperature changes in the entire dust treatment process, and it is impossible to give feedback on the site situation in the first place.
