Vertical methyl alcohol storage tank explosion-proof spray system

Abstract

The invention discloses a vertical methyl alcohol storage tank explosion-proof spray system. The system is provided with a vertical methyl alcohol storage tank and is characterized in that three temperature-pressure integrated sensors are uniformly distributed between the tank bottom and the tank top of the methyl alcohol storage tank; a cooling water spray device A and a cooling water spray device B are mounted at the top of the methyl alcohol storage tank and inside a tank body correspondingly; a circulating water storage tank A and a circulating water storage tank B are buried under the ground at one side of the methyl alcohol storage tank, and the tank bottoms of the two circulating water storage tanks communicate with each other; a water suction pump A and a water suction pump B are arranged at the top of a tank body of the circulating water storage tank B and pump water to the cooling water spray device A and the cooling water spray device B correspondingly; a water storage groove is formed in the bottom of the methyl alcohol storage tank, and a water outlet pipe is arranged on one side of the water storage groove and connected with the circulating water storage tank A; and aliquidometer and a make-up water pipe are further arranged at the tank top of the circulating water storage tank B. The vertical methyl alcohol storage tank explosion-proof spray system is simple instructure and convenient to use, and the problem of emergency fire extinguishing when the interior of the methyl alcohol storage tank is on fire and the problem of heatstroke prevention during the summer high-temperature phase are solved.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to an explosion-proof spray system for a vertical methanol storage tank. Background technique [0002] Methanol is a commonly used chemical product and the most important raw material for the production of alcohol-based fuels. Methanol is a colorless, non-flowing, non-volatile, flammable and toxic liquid at normal temperature and pressure, with an odor similar to ethanol. The boiling point of methanol at room temperature is only 64.7°C. Methanol gas and air can form an explosive mixture within a certain mixing range, and the explosion limit is 6.0%~36.5% (volume). Therefore, the fire and explosion-proof facilities of methanol storage tanks are extremely important. [0003] Currently common vertical methanol storage tanks are provided with a feed inlet and a breather valve on the top of the tank, and a discharge valve at the bottom of the tank. Since methanol is a liqui...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a vertical methanol storage tank to solve the problems of serious evaporation in the tank at high temperature in summer, which is likely to cause safety accidents, and the cost of the existing cooling facilities is high and cannot play the role of emergency fire extinguishing.
