Cooling water emergency water supply system and method

Abstract

The invention provides a cooling water emergency water supply system and method. The system comprises a high-position transfer water tank, an engine control panel, a water supply pump, a low-positionwater storage pool and a water supply pipeline. The elevation of the high-position transfer water tank meets the water pressure required by the emergency water supply to a user. The size of the high-position transfer water tank meets the requirement for at least storing 1 minute of emergency water consumption. A high-position water tank water outlet pipe and a conventional circulating cooling water supply pipe are connected with a user water inlet pipe. The user water inlet pipe supplies water to the user. A check valve is arranged on the high-position water tank water outlet pipe. A pressuresensor is arranged on the conventional circulating cooling water supply pipe. The pressure sensor is connected with the engine control panel through a circuit. The engine control panel is connected with a water supply pump through a circuit. A water outlet of the low-position water storage pool is connected with a water inlet of the water supply pump. A water outlet of the water supply pump is connected with a water inlet of the high-position transfer water tank. The system is safe, stable and convenient to maintain; and the volume of the high-position transfer water tank is small, the volumeof a supporting system of the high-position transfer water tank is smaller, and therefore flexibility of construction is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of emergency water supply, in particular to an emergency water supply system for cooling circulating water. Background technique [0002] The emergency water supply system is widely used in glass firing, silicon rod drawing, nuclear energy utilization and other fields. In the process of process production, some process equipment (such as furnaces) need a steady stream of cooling water to ensure the safe operation of the equipment. Once the flow is cut off, the equipment may be damaged, and even cause serious secondary disasters such as fire. However, due to objective factors, construction costs, and system configuration limitations, it is difficult to ensure cooling water supply in the event of power outages, equipment failures, etc. For process equipment with high water supply safety requirements, it is often necessary to be equipped with an emergency water supply system as a supplement and backup to the c...
