Inert sealing explosion suppression equipment and defense method for hazardous chemical containers

Abstract

An inert seal explosion suppression device used for hazardous chemical container, and a defense method responding to multistage shaped charge that aims at conducting sympathetic detonation on oxygen-contained hydrocarbon gas in gas-phase space of the container in a mode of detonation inside the follow-through warhead container. The device comprises an inert seal device arranged on the hazardous chemical containers. The device comprises an U-shaped sleeve (3), a Y-shaped penetrating pipe is arranged inside the U-shaped sleeve, one upper port of the U-shaped sleeve is communicated with the gas-phase of a gas inert seal medium source, the other upper port of the U-shaped sleeve (3) is communicated with the container in gas-phase state through an inert seal disc on the top of the corresponding container, a port on the gas distribution side of the Y-shaped penetrating pipe is hung in a vertical pipe on the gas distribution side of the U-shaped sleeve, a side port of the container is connected with a spraying pipe on the top of the container, a bottom port communicated with a liquid-state fire protection medium source through a bottom connection pipe of the U-shaped sleeve, that can use a liquid valve of the sleeve as a large and small breath valve, and can use a liquid valve of the penetrating pipe as a safety relief valve, that can isolate systematically the atmosphere and restrain permanently the combustion explosion condition of the gas-phase space in the container and the pipelines.

Description

technical field [0001] The invention relates to the field of safe production, storage and transportation of hazardous chemicals, in particular to an inert seal explosion suppression equipment for hazardous chemical containers, and a method for deploying the equipment to defend against attacks by Monroe effect bombs. Background technique [0002] With the advancement of ordnance technology, all kinds of high-efficiency, long-range, loitering, accurate, dexterous, and portable armor-piercing shells with shaped charges developed based on the Monroe effect are constantly innovating, widely installed, and often practiced in actual combat. In particular, the multi-stage shaped charge with a fortified attack warhead, a wall-breaking warhead and a follow-up warhead in series, targets dangerous chemicals and containers, and implements the first-stage attacking and drilling, the intermediate-stage penetration and breaking, and the final-stage With the detonation of the container, and ...

AI Technical Summary

Problems solved by technology

For example, there must be material vapor in the redundant space in the outer floating roof container; the traditional hard inner floating roof technology has many hidden dangers such as easy loosening of the guide column, easy deformation of the floating plate, easy failure of the seal, and even liquid flooding and sinking of the plate, resulting in The gas phase space of the container cannot effectively eliminate oxygen-containing hydrocarbon gases

[0008] The Chinese invention patent "Air Cushion Radial Elastic Sealed Floating Roof and Fire-fighting Method Using the Floating Roof" ZL97119189.1 invented by the inventor, although it provides a gas-type inert medium as a soft inner floating roof lining gas, it 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 many shortcomings of the soft inner floating roof provided by the US patent No. US3002828. Under the detonation situation, it is effective to prevent the oxygen-containing hydrocarbon gas from being detonated, but this prior art still has the following deficiencies in terms of military applicability: 1. Although this technical solution can deal with the following warhead to be detonated to a certain extent The oxygen-containing hydrocarbon gas pattern forms a chemical explosion strike, but does not consider the energy release function after the detonation in the container, and there is a possibility of a physical explosion in the hazardous chemical container; 2. This technical solution does not include follow-up fire protection The medium participates in the rescue or enhances the protection ability and other functions

In addition, this technical solution also has the following shortcomings in terms of industrial applicability: 1. The inert lining gas cannot be recycled; 2. The inert lining gas cannot follow the material pipeline; 3. It is impossible to separate and absorb gaseous materials from the inert lining gas

[0009] In short, the defense concept of existing technologies involving dangerous chemicals and containers is limited to non-combat prevention; the prevention strategy focuses on open fire fire fighting; the fire protection function is limited to emergency rescue
