Abstract

The invention discloses an inflaming-retardant anti-explosion method and a container thereof. The method comprises the following steps: providing a container, executing the steps, and measuring the pressure and concentration inside the container. The container is provided with a feeding port, a charging port and a discharging port, and can be sealed; after being loaded with inflammable and explosive substance and with the air being discharged, the container can be charged with and can store the inflaming-retardant anti-explosion gas, so as to separate the inflammable explosive substance and the burning-assistant gases, thereby having the inflaming-retardant and anti-explosion effect. The invention adopts the following execution steps: firstly opening the feeding port, and closing the feeding port after the inflammable and explosive substance is filled into the container; secondly opening the discharging port, and closing the discharging port after the burning-assistant gases is discharged; finally opening the charging port and charging the inflaming-retardant anti-explosion gases. Measuring the gas pressure and concentration inside the container, if the gas pressure and the concentration cannot meet the requirements, the container is charged continuously; if the gas pressure and the concentration meet the requirements, the charging port is closed, and the container stays at a sealing status. The pressure inside the container can be the normal atmosphere, and the concentration of the inflaming-retardant anti-explosion gases can be lower than the effective concentration of 100 percent. The present invention can be widely applied to the storage, transportation and processing operations of the solid inflammable and explosive substances such as the Catharine, the firecrackers, the explosives, the percussion cap, and the like.

Description

Inflatable flame-proof explosion-proof method and container
Technical field
The present invention relates to a kind of inflatable flame-proof explosion-proof method, relate to a kind of inflatable flame-proof explosion-proof container that inflammable and explosive substances store transportation and processing operation that is used for simultaneously.
Background technology
The processing of inflammable and explosive substances, storage and transportation are the important steps of safety in production.The flame-proof explosion-proof technology that is used to store and transport inflammable and explosive substances has in recent years obtained developing rapidly.The Chinese patent specification sheets, application number is 01139834.5, notification number is that CN1233536C discloses a kind of liner type obstruct anti-explosion container, its technical scheme mainly is that the reticulated aluminum Alloy Foil is made inner bag as the flame-proof explosion-proof material, be installed in the container, container is used for storing transportation liquid state or gaseous state inflammable and explosive substances, and its advantage is that flame-proof explosion-proof inner bag installing/dismounting cleans conveniently saving of work and time.But it is suitable for storing transportation liquid state or gaseous state inflammable and explosive substances, do not transport solid-state inflammable and explosive substances such as fireworks explosives and detonators and be suitable for storage, because its flame-proof explosion-proof material is a solid, be difficult to contacting of combustion-supporting gases such as isolated solid-state inflammable and explosive substances and air.
Summary of the invention
The objective of the invention is to: a kind of inflatable flame-proof explosion-proof method and container that solid-state inflammable and explosive substances store transportation and processing operation that be mainly used in is provided.
Inflatable flame-proof explosion-proof method of the present invention may further comprise the steps:
But a leakproof tank that possesses with upper shed is provided,
This container of inflammable and explosive substances rear enclosed of packing into;
By opening the combustion-supporting gas in the container is discharged;
Charge into flame-proof explosion-proof gas by opening again;
The pressure and the concentration of flame-proof explosion-proof gas in the detection receptacle if undesirable then the continuation inflated, meet
Require then closed container, make container be in sealing state.
Container of the present invention has two openings, do inflation inlet and exhausr port respectively, one of inflation inlet and exhausr port can doublely be done inlet point, also can set up an opening in addition and do inlet point, utilize the difference of specific gravity of combustion-supporting gas in flame-proof explosion-proof gas and the container, during inflation combustion-supporting gases such as air are discharged naturally, realization exhaust and inflation are carried out simultaneously.
The pressure of flame-proof explosion-proof gas can be negative pressure, normal pressure or malleation in the container of the present invention.
Flame-proof explosion-proof gas of the present invention is more than one the miscellaneous gas in one of carbon dioxide, nitrogen, heptafluoro-propane gas or unreactable gas or the above all gases.
Flame-proof explosion-proof gas of the present invention is carbon dioxide, and gas concentration is 60%~80%.
The concentration of flame-proof explosion-proof gas of the present invention is below 100%.
Have air impermeability and closure but have more than one opening on the container body of the present invention at least and have at least one deck structure to constitute, form sealed shape.
Container body of the present invention is a rigid body, and have three openings, be respectively inlet point, inflation inlet and exhausr port, inlet point, inflation inlet and exhausr port, can be directly realize opening or airtight, also can connect behind the body again row and realize opening and closing of fault by lid or door or plug or valve and packing seal.
Container body of the present invention is a flexible body, only opens the opening of hold concurrently simultaneously charging, inflation and a scavenging action.
Container body of the present invention is multilayer nest and the sir-tight container of multilayer, can charge into flame-proof explosion-proof gas between nested interlayer.
The inventive method can completely cut off contacting of the combustion-supporting gases such as inflammable and explosive substances and air in the container of packing into, thereby reaches the flame-proof explosion-proof effect.The inventive method and container are mainly used in the storage transportation of solid-state inflammable and explosive substances such as fireworks explosives and detonators, especially also are applicable to the processing operations such as pulverizing, grinding, mixing and moulding of solid-state inflammable and explosive substances.Because in the airtight container that is full of flame-proof explosion-proof gas, carry out processing such as pulverizing, grinding, mixing and the moulding operation of solid-state inflammable and explosive substances, the combustion explosion that can prevent to collide, factors such as friction and naked light causes.
