Problems solved by technology

After the actual operation on site, the above two methods have the following disadvantages: 1) the general safe water supply pressure requires 0.5 MPa or more, and the high safety water tower needs to be built at a height of more than 50 meters to meet the requirements, and the investment is high; The water tank increases the load of the factory building. In addition, due to the consideration of anti-freezing in the northern region, electric heat tracing is required, which wastes electric energy; when the power is cut off, the water tank is likely to freeze, thus posing a safety hazard; 3) The water in the accident water tank or water tower does not flow, and the water quality is easy to change Bad

Embodiment Construction

[0021] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0022] See figure 1 , is the flow chart of method of the present invention, and a kind of accident safe water supply method of the present invention comprises the steps:

[0023] 1) The circulating cooling water supply pump 18 draws cooling water from the suction well 6 of the circulating pump station, and sends the water to the water inlet pipe of the equipment 16 under pressure. production water loop;

[0024] 2) When the circulating cooling water supply pump 18 fails or the power is cut off, the accident diesel engine water supply pump 19 starts automatically, and the accident water tank 1 supplies water to the equipment 16 through the outlet pipe 21 before the accident diesel engine water supply pump 19 reaches the normal working state;

[0025] 3) The accident water tank 1 arranged in the space of the factory building column 20 forms a safe...

Abstract

The invention relates to an accident safety method and system for water supply. A circulating cooling water supply pump sucks cooling water from a circulating pump station water suction well and delivers the cooling water to an equipment flow pipe; return water returns into the circulating pump station water suction well; in the case that the circulating cooling water supply pump fails or powers off, an accident diesel engine water supply pump automatically starts up, and before the pump starts up, an accident water tank supplies water to equipment; the accident water tank and the circulating pump station water suction well form a safety water supply circulation loop through an inflow pipe and an overflow pipe; during water supply, the circulating cooling water supply pump supplements water to the accident water tank; water level of the accident water tank is observed in a control room through a level meter. Compared with the prior art, the accident safety method and system for water supply has the advantages that the accident water tank is disposed in column space of a workshop, load of the workshop is never increased, and investment is low; the safety water supply circulation loop is formed through the inflow pipe, an outflow pipe and a lower horizontal overflow pipe, the water in the accident water tank is kept flowing, water worsening is avoided at the premise of meeting safety of water supply, and the anti-freezing problem is solved.

Description

technical field [0001] The invention relates to the technical field of safe water supply in industrial production, in particular to an accident safe water supply method and a water supply system. Background technique [0002] At present, accident safety water supply systems for continuous casting, cold rolling, and galvanizing production lines in iron and steel enterprises generally use a combination of diesel engine pumps and high-level safety water towers, or a combination of diesel engine pumps and high-level safety accident water tanks. After the actual operation on site, the above two methods have the following disadvantages: 1) The general safe water supply pressure requires 0.5MPa or more, and the high safety water tower needs to be built at a height of more than 50 meters to meet the requirements, and the investment is high; 2) Safety accidents are installed on the roof of the factory building. The water tank increases the load of the factory building. In addition, d...
