Description

Circulation inert sealing system and QHSE storage and transport method based on gas source servo device

The present invention relates to the field of storage and transportation of bulk liquid hazardous chemicals, and in particular, to the field of self-defense technology for military petroleum supply processes, and in particular, the present invention relates to a gas source servo device, a circulating inert sealing system based on the device. And a storage transport method that integrates (hereinafter referred to as QHSE) quality, health, safety and environment based on the system.

Materials with strategic resource attributes such as petroleum and its products are not only supporting national power, but are also a part of combat power. Since these materials and their storage and transportation methods, processing facilities and technical equipment are commonly used by the military and public during the period of peace and war, they inevitably become the focus of strategic interests and a strategic point of attack and defense during military struggles. However, under the background of modern aggression combat power, which is a common and frequently used type of ammunition in the form of tandem shaped charges, as a means of constant threats, piercing the wall breaking holes by the first-stage penetration and entering the container following the end combat section. The subsequent effect of aggressive damage, which causes a net chemical explosion, and explodes oil and gas, and causes an overall chemical explosion, is remarkable and the cost-effectiveness ratio is high. Accordingly, the military oil supply process, national strategic stockpile, chemical It has become a basic method of destroying important military and economic targets such as industrial parks and battleships, ship-powered oil tanks, roads and railroads, and the type of ammunition of an essential option and the optimal tactic. Therefore, in the conventional military oil supply process, the self-defense technique is limited only within the scope of the underground warehouse concealment process and the firefighting technique, and the self-defensive combat power in response to the attack in the explosion mode in the container becomes an indispensable means.

In addition, as is well known, materials of bulk liquid hazardous chemicals are known precursor pollutants, carcinogens, smog, due to volatile organic compounds (VOCS) generated by interphase mass transfer. It has become a causative agent and a contributor to the greenhouse effect, and is also a major target of government management in the categories of public safety, life health, environmental protection, clean production, product quality, energy conservation, and pollutant emission reduction. However, the different categories of prior art regarding bulk liquid hazardous chemicals and containers have conflicting process processes. For example, a container without an internal floating loop is considered amorphous drainage technology, and the existing internal floating loop storage tank ensures the fluency of breathing by opening a ventilation window, eliminating the safety risk of oil gas collection. However, air pollution caused by continuous volatilization and loss on the sealing device side is not within the scope of compulsory management; Although the existing internal floating loop nitrogen additional sealing technology further secured the oxygen emission safety of the system and suppressed material oxidation and deterioration, when interfacial material transfer is in the storage tank exhaust gas, nitrogen gas is accompanied and discharged. Environmental pollution and safety problems of pressure relief valves have not been solved; Although the existing self-sealing gas-liquid training type oil gas recovery technology has reduced environmental pollution in the loading and unloading stages of materials, this is a method that parallels the input and output side vessels with gas as a medium, and the risk of combustion and explosion of the mixed gas in the material output side container It is not applicable to various floating roof tanks due to the rapid increase.

Therefore, the technical solution applied to the entire storage and transport chain network, which blocks the atmosphere in the normal state, circulates dynamically inert sealing, does not have vapor emission, is inexpensive, and is compatible with the advanced value of the technology area.

This technical solution, although the technical purpose of circulating and filling the gaseous space of the material container with a gaseous inert sealing medium, is to control the normalization of oxygen content to be less than the lower limit of the protected material combustion explosion limit.

Feedback control of the state of the working gas on the gas receiving side is maintained so as not to exceed the range of the predetermined pressure parameter. The gas filling check valve A2 matches the rated exhaust pressure of the gas receiving compressor A1, and is installed in the pipeline between the exhaust side of the gas receiving compressor A1 and the gas entry side of the gas source container A3, In cooperation with the gas source vessel A3, the working gas is recovered and stored and pressure potential energy is accumulated.
