Abstract

The invention relates to the field of liquefied hydrocarbon discharging, and discloses an anti-static emptying device for the liquefied hydrocarbon. The emptying device comprises a leading-in unit, agas storage unit and a discharging unit, wherein the leading-in unit is used for leading in the liquefied hydrocarbon and providing a gasifying environment, wherein the liquefied hydrocarbon is changed into gasification hydrocarbon after being gasified; the gas storage unit is used for accommodating the gasification hydrocarbon; the diameter of an opening of the discharging unit is greater than that of the opening of the leading-in unit; and the opening of the discharging unit is opened automatically to discharge the gasification hydrocarbon from the gas storage unit when the pressure of the gasification hydrocarbon in the gas storage unit is greater than a preset threshold value. According to the anti-static emptying device for the liquefied hydrocarbon, the discharging flow speed of theliquefied hydrocarbon can be greatly reduced so as to reduce the production of friction static electricity and ensure the static safety in a liquefied hydrocarbon

Description

technical field [0001] The invention relates to the field of liquefied hydrocarbon discharge, in particular to an antistatic emptying device for liquefied hydrocarbons. Background technique [0002] When the quick connector is separated after the liquefied hydrocarbon loading and unloading truck is completed, it is necessary to drain the residual liquid in the straight pipe section of the crane pipe and the tank car joint, and the on-site discharge will bring potential safety hazards. Create an explosive environment. The residual liquid is discharged through a ball valve or a needle valve and gasified. Since the gas-liquid volume ratio of liquefied hydrocarbons is about 1:300, during the gasification process, gasified hydrocarbon molecules rub against each other due to high-speed motion, thereby generating static electricity. , if the generated static electricity accumulates, it will cause a static electricity explosion accident. Contents of the invention [0003] The ob...
