Circulating spraying cooling system for vertical type methyl alcohol storage tank

Abstract

The invention discloses a circulating spraying cooling system for a vertical type methyl alcohol storage tank. The system is provided with the vertical type methyl alcohol storage tank. The system ischaracterized in that a cooling water spraying device is arranged on the top of the methyl alcohol storage tank, the cooling water spraying device comprises an inner circle of annularly-distributed spraying pipe and an outer circle of annularly-distributed spraying pipe, and the inner circle of annularly-distributed spraying pipe and the outer circle of annularly-distributed spraying pipe are bothconnected with a water supply main pipe; a circulating water storage tank A and a circulating water storage tank B are buried in the portion, located on one side of the methyl alcohol storage tank, of the underground, the tank bottoms of the two circulating water storage tanks communicate with each other, a filter a is arranged on the middle upper portion of a tank body of the circulating water storage tank A, and a filter b is arranged on the middle lower portion of a tank body of a tank body of the circulating water storage tank B; a water suction pump is arranged on the top of the tank body of the circulating water storage tank B and sucks water to the water supply main pipe; a water storage tank is arranged at the bottom of the methyl alcohol storage tank, and a water outflow pipe isarranged on one side of the water storage tank and connected with the circulating water storage tank A; and a liquidometer and a supplementing water pipe are further arranged on the top of the circulating water storage tank B. The circulating spraying cooling system is simple in structure and convenient to use, and the problem about heatstroke preventing and cooling in the high-temperature periodof the methyl alcohol storage tank is solved.

Description

Technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a vertical methanol storage tank circulating spray cooling system. 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 under normal temperature and pressure, with an odor similar to ethanol. The boiling point of methanol at room temperature is only 64.7℃. 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, fire-proof and explosion-proof facilities for methanol storage tanks are extremely important. [0003] At present, the common vertical methanol storage tank is provided with a feed port and a breathing valve on the top of the tank body, and a discharge valve is provided at the bottom of the tank body. Since...
