Abstract

The invention discloses a combined power-plant fireproof explosion-proof purging system and a control method. The system comprises fire-fighting gas purging equipment, field measurement and control equipment and a purging control subsystem; the purging control subsystem comprises a fire-fighting gas bottle, a humidifying refrigerator, an air compressor unit and a gas collecting pipe, outlet pipesof the fire-fighting gas bottle, the humidifying refrigerator and the air compressor unit are communicated with the gas collecting pipe through control valves respectively, and an outlet end of the gas collecting pipe is connected to a high-speed gas flow nozzle and a gas guiding wind curtain; the field measurement and control equipment comprises a gas concentration meter, a local interlocking switch, a local sound and light alarm and an industrial television monitor; a control bus is in signal connection with the gas concentration meter, the local interlocking switch, the local sound and light alarm and the industrial television monitor through control sub-lines; a valve control box is electrically connected with all the control valves. The system is simple in structure, mature in technology, low in failure rate, high in reliability, low in cost and expense and simple in daily operation and maintenance.

Description

technical field [0001] The invention relates to the field of fire protection, relates to the fire protection technology of power plants, and in particular to a combined fire and explosion-proof purging system and control method for power plants. Background technique [0002] Among the materials required for the production process of thermal power plants, many are flammable and explosive, such as: coal powder and fuel oil for boilers, hydrogen for cooling generators, diesel fuel for diesel generators, transformers and high-voltage electrical appliances Insulating oil, out-of-market agent liquid ammonia, etc. Combustible gas, dust, oil mist and air are mixed to reach the explosion concentration. Once the ignition energy is encountered, the explosion is very likely to occur. The stock of combustible materials in power plants is very large. If the fire spreads, it will be extremely difficult to control it in a short time and in a small area, which will inevitably cause major co...
