A safety device for volatile liquid storage

Abstract

The invention discloses a storage safety device for volatile liquid, and relates to the technical field of volatile liquid storage. The device comprises a tank body, a base and a fixed seat; a condensation recovery chamber is arranged in the base; a pressure relief chamber is arranged in the fixed seat; a third through hole and a fourth through hole are respectively formed in the bottom of the pressure relief chamber; a peripheral side surface of the third through hole is fixedly connected with a pressure relief pipe; a plurality of breather pipes are mounted close to the top of the peripheralside of the tank body; one end of each breather pipe penetrates through the peripheral side of the pressure relief pipe; a third spring is mounted at one end, away from the tank body, in the breatherpipe; and one end of the third spring is fixedly connected with a sliding block. Through the design of the third spring, the sliding block, the pressure relief pipe and the pressure relief chamber, automatic pressure control can be achieved, the structure is simple, and safety is high; through the design of a refrigeration control box, a spiral condensation pipe and the condensation recovery chamber, gas liquefaction can be achieved, the temperature in a spiral condensation pipe is reduced, the tank body is effectively cooled, liquid volatilization is reduced, and the safety is high.

Description

technical field [0001] The invention belongs to the technical field of liquid storage, in particular to a safety device for volatile liquid storage. Background technique [0002] Volatile liquids refer to those liquids that have a low boiling point and can be volatilized to form a gas state at room temperature. Volatile liquids are mainly organic substances, such as methanol, ethanol, acetic acid, etc., and some inorganic liquids are also volatile, such as ammonia water, concentrated hydrochloric acid, concentrated nitric acid, etc. One of the main problems to be solved in the storage and transportation of volatile liquids is the gas pressure inside the storage device. This is the main indicator of safety. The quality of the pressure control device is directly related to the safety of storage and the life safety of transport personnel. [0003] At present, in terms of liquid storage, especially when storing volatile liquids, because the liquid is easy to volatilize, especia...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a safety device for volatile liquid storage, through the design of vent pipe, third spring, slide block, spiral condensation pipe, return pipe and condensation recovery chamber, it solves the problem of existing volatile liquid storage The structure of the device is complex, the safety is not high, and it is not convenient for automatic pressure control. The volatilized gas is easily discharged into the environment, causing environmental pollution or endangering human health. There is no gas liquefaction mechanism, and the volatilization speed of volatile liquid cannot be effectively controlled.
