Device and method for supplying seawater to fire protection water storage tank for petrochemical library

Abstract

The invention provides a device and method for supplying seawater to a fire protection water storage tank for a petrochemical library. The device comprises a high-reliability, maintenance-free and movable emergency pump station which is arranged on the seashore. The high-reliability, maintenance-free and movable emergency pump station comprises a cam rotor pump, an air-cooled diesel engine, a double-energy starting system and a moving device. One end of a suction water pipe is connected with the water inlet of the high-reliability, maintenance-free and movable emergency pump station, and the other end of the suction water pipe is thrown into seawater. One end of a water drain pipe is connected with the water inlet of the high-reliability, maintenance-free and movable emergency pump station, and the other end of the water drain pipe is connected with the fire protection water storage tank. The device has the advantages of being reliable in performance, and low in manufacturing and maintaining cost.

Description

technical field [0001] The invention relates to the field of fire protection in the petrochemical industry, in particular to a device and method for replenishing seawater to a fire storage tank for petrochemical storage. Background technique [0002] At present, with the rapid development of the petrochemical industry, my country has built a large number of petrochemical facilities, oil depots, and gas depots in coastal areas, and simultaneously built large-capacity fire-fighting water supply pumping stations for fire-fighting needs. The construction of a fire pump station must first solve the water source problem of fire water supply. There are several solutions in the traditional technology: [0003] 1. Use fresh water as water source [0004] This plan requires the construction of large-capacity water storage tanks. When petrochemical companies expand their production scale, the capacity of the water storage tanks needs to be increased accordingly, or multiple water stor...

AI Technical Summary

Problems solved by technology

[0007] 2.1. The fire water supply system is severely corroded

[0009] 2.2. The suction pipe of the feed water pump is prone to blockage

[0010] Although the suction pipe of the seawater fire pump is located close to the bay, when the sea tide rises and ebbs, the waves carry sea sand, seaweed and other marine organisms into the suction pipe, and the sea sand even buries the suction pipe deeply, and the suction pipe is blocked. system unavailable

However, the workload of cleaning the suction pipe is large, and the maintenance cost is very high.

[0011] 2.3. Cavitation occurs in the feed water pump due to wave troughs

These factors lead to the very expensive cost of the above-mentioned design scheme (to build a small fire pump station, the cost is also tens of millions of yuan)
