Problems solved by technology

Since the electrostatic discharge of the human body is the main ignition source in the liquid hydrocarbon loading area, the liquid hydrocarbon loading and unloading workers need to wear anti-static shoes and clothing, but usually these anti-static shoes and clothes will not be used due to their own quality, long-term cleaning and / or exceeding the use time limit. Compliance with safety standards

Abstract

The invention relates to the field of electrostatic protection, and discloses an electrostatic monitoring system and electrostatic monitoring method for a liquefied hydrocarbon vehicle-loading area. The electrostatic monitoring system comprises an opening and closing device, an electrostatic monitoring device and a control device, wherein the opening and closing device is mounted between a slot vehicle inlet and a tail end of a loading and unloading arm and used for connecting or cutting off a pipeline between the slot vehicle end inlet and the tail end of the loading and unloading arm to openor stop a loading operation of liquefied hydrocarbon; the electrostatic monitoring device is used for monitoring static data around the opening and closing device; and the control device is used forcontrolling the opening and closing device to be disconnected under the condition that the electrostatic data exceed a preset electrostatic threshold so as to cut off the pipeline between the slot vehicle inlet and the tail end of the loading and unloading arm. By the adoption of the electrostatic monitoring system, the fire explosion accident caused by too high static electricity in the liquid hydrocarbon vehicle-loading operation can be prevented, so that the safety of the on-site operation is ensured.

Description

technical field [0001] The invention relates to the field of electrostatic protection, in particular to an electrostatic monitoring system and an electrostatic monitoring method used in a liquefied hydrocarbon loading area. Background technique [0002] At present, the loading and unloading of liquefied hydrocarbons mostly adopts the lever type quick connector. The material of the quick connector is brass or stainless steel. The male and female connectors of the quick connector adopt a straight-through structure. The loading and unloading arm end joint is opened and closed by the rear end ball valve. Once the quick joint falls off or leaks, the straight-through joint cannot be quickly cut off to prevent the leakage of liquefied hydrocarbons; in addition, the quick joint will also leak liquefied hydrocarbon residual liquid during normal use. Leaked liquefied hydrocarbons gasify to form an ignitable and explosive atmosphere. Once an ignition source (open flame, lightning, sta...
