Abstract
The invention relates to the field of a firefighting device, and particularly relates to a liquid nitrogen extinguisher. The invention relates to a long-acting storage tank of an automobile liquid nitrogen extinguisher. The long-acting storage tank comprises an outer tank body and an inner tank body, wherein the tops of the outer tank body and the inner tank body are provided with a seal cover, so that a vacuum chamber is formed between an outer insulation layer and an inner insulation sleeve, and an elastic supporting rod is arranged at the bottom axis parts of the outer tank body and the inner tank body; an outlet pipe is communicated with the vacuum chamber by virtue of a decompression valve; a vacuum pump is arranged outside the outer tank body; the vacuum pump is communicated to the vacuum chamber by virtue of a pipeline; the vacuum pump is provided with a vacuum meter and a controller; the vacuum meter inputs a signal to the controller, and the controller is in control connection with the vacuum pump. The decompression valve is communicated into the vacuum chamber, and the insulation layer can be cooled by utilizing the discharged nitrogen at every-time decompression, so that the heat transferred into the inner tank body from the exterior is reduced, and the initiative exhaustion amount needed for the heating of the liquid nitrogen is reduced, and the shelf life of the liquid nitrogen extinguisher can be increased by around 2 to 5 times, and the practicability of the liquid nitrogen extinguisher is greatly improved.
Description
Technical field
The present invention relates to fire-fighting equipment field, particularly relate to a kind of fire extinguisher of liquid nitrogen.
Background technology
In existing fire-fighting equipment, portable mobile fire extinguisher is all water spray fire extinguisher, dry powder extinguisher, carbon dioxide extinguisher or foam annihilator usually, these fire extinguishers are little for the usual problem of fire of conventional fire or predetermined substance above, but often on the contrary can be combustion-supporting for special chemical fire, even cause blast, therefore chemical laboratory or hazardous chemical are stacked for place, need a kind of wide spectrum fire extinguisher to ensure safety.
The best wide spectrum fire extinguisher of existing effect is fire extinguisher of liquid nitrogen, but fire extinguisher of liquid nitrogen also could not be applied, this is because this type of fire extinguisher is because tank body volume is limited, therefore thermal-insulating sealing is limited in one's ability, helium leak amount is very large, cause the shelf-life very short, usually 48 hours are no more than, this storage cost obviously can not be easily accepted by a user, therefore only liquid nitrogen can be produced in most advanced laboratory or self, the factory with large-scale liquid nitrogen storage tank could apply, and cannot meet the needs of domestic consumer.
Summary of the invention
Vacuum chamber is separated out with thermal insulation layer in this tank body of long-acting storage tank that technical problem to be solved by this invention is to provide a kind of automobile-used fire extinguisher of liquid nitrogen, and relief valve is communicated in vacuum chamber, can utilize during each pressure release and be unloaded the nitrogen cooling thermal insulation layer of releasing, reduce the outside heat be passed in interior tank body, reduce liquid nitrogen because the initiative exhaust amount required for heating up, the fire extinguisher of liquid nitrogen shelf-life about 2 ~ 5 times can be extended through measuring and calculating, substantially increase the practicality of fire extinguisher of liquid nitrogen.
The present invention is achieved in that a kind of long-acting storage tank of automobile-used fire extinguisher of liquid nitrogen, comprise outer tank body and interior tank body, the top of described outer tank body is provided with Cap for tin body, described interior tank body is arranged in outer tank body, interior tank body top open part is connected with drain valve by outlet, certain interval is left between outer tank body and interior tank body, described drain valve is arranged on Cap for tin body, the inwall of described outer tank body is provided with outer thermal insulation layer, inner canister extracorporeal set has interior collet, the top of described outer tank body and interior tank body is provided with seal cover to be made to become vacuum chamber between outer thermal insulation layer and interior collet, axle center, the bottom place of outer tank body and interior tank body is provided with elastic supporting bar, the middle part of outer thermal insulation layer and interior collet is provided with some resilient support arms, described outlet is communicated with by relief valve with between vacuum chamber,
Described outer tank body is outside equipped with vavuum pump, and described vavuum pump to vacuum chamber, vavuum pump is provided with vacuum meter and controller by pipeline connection, vacuum meter input signal to controller, controller control connection vavuum pump.
Liquid level gauge is provided with in described interior tank body.
Described interior tank body is communicated with Pressure gauge.
Described Cap for tin body top outer also Central Symmetry is provided with a pair handle.
Vacuum chamber is separated out with thermal insulation layer in this tank body of long-acting storage tank of the automobile-used fire extinguisher of liquid nitrogen of the present invention, and relief valve is communicated in vacuum chamber, can utilize during each pressure release and be unloaded the nitrogen cooling thermal insulation layer of releasing, reduce the outside heat be passed in interior tank body, reduce liquid nitrogen because the initiative exhaust amount required for heating up; After pressure release discharge, controller vacuumizes process according to the data of vacuum meter again to vacuum chamber, can not affect the heat-insulating capability of tank body; The shelf-life of fire extinguisher of liquid nitrogen can be significantly improved after using this tank body, the fire extinguisher of liquid nitrogen shelf-life about 2 ~ 5 times can be extended through measuring and calculating, substantially increase the practicality of fire extinguisher of liquid nitrogen.
