Description

Idle-sealed anti-explosion equipment for dangerous chemical containers and defense method

Technical field

The invention relates to the field of safe production, storage and transportation of dangerous chemicals, in particular to an inertial sealing and anti-explosion device for a dangerous chemical container, and a method for arranging the equipment to defend against the Monroe effect.

Background technique

With the advancement of ordnance technology, various types of high-efficiency, long-range, patrol, precision, dexterous, portable and other energy-generating armor-piercing ammunition developed based on the Monroe effect are constantly innovating, universally installed, and practiced. In particular, there are multi-stage shaped charge in the series, including the attacking warhead, the broken wall warhead and the accompanying warhead. The dangerous chemicals and containers are targeted, and the pre-level drills are drilled, the intermediate level penetrates the wall, and the final stage With the detonation of the container, the oxygenated hydrocarbon gas in the gas phase of the vessel is blasted, resulting in a blow mode of the overall chemical explosion, strong damage and high cost-effectiveness. It is an important military and economic target for destroying military oil depots and heavy chemical parks. Optimal tactics and mandatory bombs.

As we all know, energy-based materials such as crude oil and fuel oil with strategic resource attributes and their production, storage and transportation facilities and equipment are important support for national power and an important component of combat power. Because such materials and containers have typical characteristics such as military-civilian sharing, peacetime generalization, and asset agglomeration, they must become strategic interests and tactical offensive and defensive in military operations such as military confrontation or terrorist attacks. In particular, driven by the growing shortage of energy and the sharp increase in demand, a large number of dangerous chemicals and containers that are capable of forming multiple damages and causing major damages are indiscriminately exposed to densely populated and unpredictable economic and strategic locations.

Obviously, hazardous chemicals and containers are indispensable for technical equipment and defense methods that attack the Monroe effect.

The tactical technical equipment and defense methods of the existing military oil depot only involve the cave library hidden Covered, semi-underground camouflage, floating roof technology and other fire-fighting fields for kinetic energy and combustion-type bomb attacks, but in the context of modern investigative, guidance and multi-level charges, the independent defense force is ineffective.

The known anti-explosion material application technology can release the substance which inhibits the formation of free radicals when the material temperature rises rapidly, but the alloy-like grid-like anti-explosion material cannot inhibit the formation of oxygen-containing hydrocarbon gas in the gas phase space of the container, so It is not possible to suppress the oxygenated hydrocarbon gas from being detonated in the event of a detonation in the vessel.

Although the known floating roof technology provides a technique and method for suppressing a large amount of evaporation of materials, there are many disadvantages in terms of military applicability and industrial applicability. For example, the redundant space in the outer floating roof container must contain material steam; the traditional rigid inner floating roof technology has many hidden dangers such as easy to loose guide column, easy deformation of the floating plate, easy to seal, and even liquid pan. The gas phase space of the vessel cannot effectively eliminate the oxygenated hydrocarbon gas.

The Chinese invention patent "Air Cushion Radial Elastic Sealed Floating Roof and Fire Fighting Method Using the Floating Roof" ZL97119189.1, which is invented by the inventor, provides a gas-type inert medium as a soft inner floating lining gas, which is normalized. The technical solution of covering the surface of the protected material overcomes many defects of the hard inner floating roof, and makes up for the shortcomings of the soft inner floating roof and the unused inertial sealing gas provided by the US Patent No. US3002828, which can be in the container. In the case of detonation, the effective defense against oxygenated hydrocarbon gas is detonated. However, this prior art still has the following shortcomings in military applicability: 1. Although the technical solution can cope with the warfare part to some extent The oxygen-containing hydrocarbon gas mode forms a chemical explosion, but does not consider the energy venting function after the detonation in the container, and there is a possibility of physical explosion of the hazardous chemical container; 2. The technical solution does not carry out follow-up fire The media participates in functions such as saving or enhancing protection. In addition, the technical solution also has the following shortcomings in industrial applicability: 1. The inert gas line cannot be recycled; 2. The inert gas line cannot follow the material pipe; 3. The gas can not be separated from the inert gas line and the gas material can be extracted.

In short, the prior art is concerned with the defensive concepts of hazardous chemicals and containers. War prevention; prevention strategy focuses on open fire; fire protection is limited to emergency rescue.

detailed description

The technical solution of the present invention will be further described in detail below through the accompanying drawings and embodiments.

FIG. 1 is a schematic view showing the structure of an embodiment of an inertial seal suppression device for a hazardous chemical container according to the present invention. In the present embodiment, the inert seal explosion-proof equipment for the hazardous chemical container includes an air-sealing device disposed on the hazardous chemical container 1, and the air-sealing device includes a U-shaped sleeve 3 installed in a vertical direction, a U-shaped sleeve The tube 3 stores a liquid fire-fighting medium having a fire-fighting function with respect to the protected material in the dangerous chemical container, and the U-shaped sleeve 3 includes a gas distribution side vertical pipe, a container side vertical pipe and a bottom joint pipe, and a bottom pipe The two ends of the U-shaped sleeve 3 are respectively connected to the lower port of the gas distribution side vertical pipe and the container side vertical pipe, and the upper port of the gas distribution side vertical pipe of the U-shaped casing 3 is capable of being supplied and recovered with respect to the hazardous chemical container 1 The gaseous inerting medium source 5 of the chemically stable gaseous inerting medium 6 of the protected material 2 is in communication, and the upper port of the container-side vertical tube of the U-shaped casing is in communication with the top of the hazardous chemical container 1.

The gas distribution side vertical pipe, the container side vertical pipe and the bottom coal pipe in the U-shaped casing 3 can be respectively It can be made and connected in turn, or it can be manufactured in one piece. The U-shaped sleeve 3 may be installed wholly or partially outside the hazardous chemical container 1, or may be wholly or partially installed inside the hazardous chemical container 1, and the entire U-shaped sleeve 3 in Fig. 1 is installed in a hazardous chemical. The outer side of the container 1, and for a hazardous chemical container 1, a plurality of U-shaped sleeves 3 may be provided, distributed outside the hazardous chemical container 1, or may be disposed in the hazardous chemical container 1, for example An internal pipe passage is provided in the side wall of the hazardous chemical container 1, and a part of the U-shaped sleeve 3 may be disposed outside the hazardous chemical container 1 and the other portion may be disposed in the hazardous chemical container 1.

Since the gaseous inert seal medium always fills the gas phase space of the container and can be output and increased as the gas phase space in the container is reduced, the pressure in the gas phase space can be designed and regulated according to the saturated vapor pressure of the material to be protected. The equipment can effectively prevent the combustion of explosive conditions from being achieved when the material to be protected is always isolated from the air.

An important aspect of the invention is that the liquid fire-fighting medium is used as a self-controlling casing liquid valve between the source of the gaseous inerting medium and the dangerous chemical container by adopting a technical measure of filling the U-shaped casing with a liquid fire-fighting medium. The inert seal medium is divided into two parts: the gaseous inerting medium on the gas distribution side and the gas inerting medium on the container side, which effectively supports the size and breathing of the hazardous chemical container, and prevents the material vapor and the gaseous inert seal medium from escaping into the air. Under the premise of dispersing, the simplification replaces the large and small breathing valves, fire-blocking valves, safety relief valves, rupture discs and other accessories commonly used in hazardous chemical containers to achieve energy saving and emission reduction, and improve safety and reliability.

The concept of "lazy seal" as used in this specification is not limited to the well-known concept of "nitrogen seal". It should be understood that a suitable gaseous inert seal medium is selected according to the requirements of the material to be protected and the container, for example, selected from nitrogen, zero rare gas. a combination of one or more of carbon dioxide gas and water vapor.

“Small breathing” as used in this specification refers to the volume of the gas phase space of the container due to the environment. (ie, the external environment of the container), the container (ie, the dangerous chemical container in the foregoing), the temperature of the gas in the gas phase space in the material and the container, and the output or input of part of the gas is required to ensure the balance between the gas phase space of the container and the atmospheric pressure outside the container.

The small breathing of the container based on the above technical solution is realized: when the temperature of the gas in the gas phase space in the environment, the container, the material and the container is increased, the material expands, the liquid level of the material rises, the volume of the gas phase space of the container decreases, and the pressure of the gaseous inert seal medium Raising, the liquid level of the liquid fire-fighting medium in the pipeline driving the side of the U-shaped sleeve near the container is lowered, and the liquid level of the liquid fire-fighting medium in the pipeline near the source side of the gaseous inerting medium is raised; When the temperature of the gas in the gas phase space in the environment, the container, the material and the container is lowered, the material shrinks and the liquid level decreases, causing the gas phase space volume of the container to increase, and the pressure of the gas inerting medium is lowered, and the U-shaped sleeve is close to the container. The liquid level of the liquid fire-fighting medium in the standpipe on one side rises, and the level of the liquid fire-fighting medium in the line near the source side of the gas-laden seal medium decreases. It can be seen that the liquid fire-fighting medium in the U-shaped sleeve can be used as a casing liquid valve to adjust and control the pressure of the gaseous inert medium in the container by using the automatic adjustment of the liquid level.

The liquid fire fighting medium herein may be selected from the group consisting of water, antifreeze, parent material liquid, water based fire fighting foam.

The term "big breath" in this specification refers to the operation guarantee that the gas phase space of the container needs to be output or input a large amount of gas when the container is received or fed.

The large breathing of the container based on the above technical solution is realized: during the receiving operation, the liquid level of the material gradually rises, the gas phase space in the container gradually decreases, and the pressure of the gaseous inert sealing medium on the inner side of the container and the U-shaped sleeve gradually increases. Raising, which lowers the liquid level of the liquid fire-fighting medium in the vertical tube near the container side of the U-shaped sleeve, and the liquid level of the liquid fire-fighting medium in the vertical tube on the source side of the gaseous inerting medium rises when When the pressure reaches the design value, the gas collection system of the gaseous inert seal medium source is started, the pressure on the side is lowered, and the liquid fire-fighting medium in the side vertical pipe is returned to the container side vertical pipe under the action of gravity. The flush release gaseous inert seal medium flows to the source of the gaseous inert seal medium, and the gaseous inert seal medium is filtered, washed, and depressurized by the liquid fire medium to be returned to the gaseous inert seal medium source for recovery until the system pressure is equalized; During the material feeding operation, the liquid level of the material gradually decreases, the gas phase space of the container gradually increases, and the pressure of the gaseous inert sealing medium in the container and the side vertical tube of the U-shaped sleeve container gradually decreases, so that the liquid fire-fighting medium liquid in the side vertical tube The surface gradually rises, and the liquid level of the liquid fire medium in the riser near the source side of the gaseous inert seal medium decreases. When the pressure reaches the design value, the gas supply system of the gaseous inert seal medium source starts, and the container side riser The liquid fire-fighting medium is recirculated to the gas medium source side by gravity under the action of gravity, and the gaseous inert seal medium is pulsed into the container, and the gaseous inert seal medium is filtered and vented by the liquid fire-fighting medium, and then enters into the container until The delivery operation is completed or the system pressure is balanced.

As can be seen from the above description, the liquid fire-fighting medium filled in the U-shaped sleeve can divide the gaseous inert sealing medium into a gaseous inert sealing medium close to the gas distribution end of the gas inerting medium source side and a gas inertial sealing medium at the container end. The elastic pressure adjustment of the gaseous inert seal medium can be realized, and the gaseous inert seal medium passing through can also be filtered and cleaned during large breathing. In addition, since the gaseous inert seal medium source can recover the gaseous inert seal medium in the container during the container receiving operation, the material vapor molecules mixed in the gaseous inert seal medium can be separated and extracted, and then, when the container is being fed A relatively pure gaseous inert seal medium is provided within the vessel to effect recycling of the gaseous inert seal medium.

When performing the task of outputting all the materials in the container, such as pouring cans, repairing, cleaning the container, etc., the traditional operation mode can only suck air into the pipeline, which poses a major safety hazard. According to the idle seal explosion-proof equipment provided by the invention, the gaseous inert seal medium can be carried into the material pipeline, and the inert seal can be implemented, thereby eliminating the safety hazard due to the inability to seal the material pipeline.

2 is a schematic structural view of another embodiment of the inertial seal suppression device for a hazardous chemical container according to the present invention. Compared with the previous embodiment, the embodiment further includes a liquid The fire medium source 7 and the liquid fire medium source 7 are in liquid phase communication with the U-shaped sleeve 3, and provide, discharge, recycle or recycle the liquid fire-fighting medium to the inside of the U-shaped sleeve 3. The liquid fire-fighting medium in the U-shaped casing separates the gaseous inerting medium into two parts, a gaseous inerting medium on the gas distribution side and a gaseous inert gas sealing medium on the container side.
