Abstract
The invention relates to a throwing type carbon dioxide and dry powder bursting eruption fire extinguisher. The fire extinguisher comprises a dry powder extinguishing agent container and a sealing member of a blast hole (13), wherein the dry powder extinguishing agent container is used for containing a dry powder extinguishing agent; the blast hole (13) is formed in the wall of the container; the dry powder extinguishing agent container is connected with a carbon dioxide container for containing liquid carbon dioxide through a pressure-limiting valve; the pressure-limiting valve is ejected by carbon dioxide after the liquid carbon dioxide is evaporated due to heating and a pressure in the carbon dioxide container reaches a pressure-limiting valve opening value, so that carbon dioxide enters the dry powder extinguishing agent container; the sealing member is ejected by a mixture of carbon dioxide and dry powder extinguishing agent after carbon dioxide enters the dry powder extinguishing agent container and the pressure in the dry powder extinguishing agent container reaches a bursting eruption value, so that the mixture is erupted from the blast hole (13). Fire is extinguished by bursting eruption of the mixture of carbon dioxide and dry powder extinguishing agent in a throwing manner, and the fire extinguisher can be repeatedly used without causing a secondary disaster.
Description
Technical field
The present invention relates to a kind of fire extinguisher, specifically a kind of throwing type fire annihilator.
Background technology
The quick-fried spray fire extingusher of existing dry powder is generally portable injecting type, needs operator's hand extinguisher near the burning things which may cause a fire disaster operation at the fire fighting scene.Therefore, can't near in the situation of burning things which may cause a fire disaster, perhaps under enclosed environment, use existing dry powder extinguisher to bring threat to firefighter's safety.
Also has a kind of throwing explosion type fire extinguisher, fire extinguisher can be thrown in the scene of a fire, fire extinguisher is subjected to thermal explosion, extinguishing chemical sheds and realizes fire extinguishing, although can solve above-mentioned can't be near the defective of burning things which may cause a fire disaster fire fighting, fire extinguisher is scraped can't be recycled, cause use cost too high, and blast can bring uncontrollable secondary disaster, such as wound or blast to death personnel in the scene of a fire, blows up property etc. in the scene of a fire.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of throwing type carbon dioxide dry powder quick-fried spray fire extingusher, utilize the quick-fried spray fire extinguishing of mixture of carbon dioxide and powder extinguishing agent, and fire extinguisher can reuse, do not produce secondary disaster, to overcome the defective of existing fire extinguisher.
In order to solve this technical problem, the present invention by the following technical solutions:
(same claims)
Good effect of the present invention is:
The first, after being thrown into this fire extinguisher in the scene of a fire, liquid carbon dioxide in the CO 2 vessels (such as coil pipe) is heated and vaporizes rapidly, volume significantly expands and produces high pressure with the bursting of pressure limiting sheet, carbon dioxide enters the powder extinguishing agent space and mixes with powder extinguishing agent, quick-fried spray orifice is opened, the quick-fried spray of the mixture of carbon dioxide and powder extinguishing agent and going out reaches the fire extinguishing purpose.Utilized the dual fire extinguishing effect of carbon dioxide and powder extinguishing agent, and not blast in the quick-fried spray process, secondary disaster do not produced.The second, by replenishing liquid carbon dioxide, powder extinguishing agent, change the pressure limiting sheet, can reuse this fire extinguisher, reduced use cost.Three, under the non-working condition, utilize the sealing process of valve rod the inner, liquid carbon dioxide can't enter valve pocket, the pressure limiting sheet is pressure-bearing not, even and the CO 2 vessels accident is heated, carbon dioxide wherein can not act on the pressure limiting sheet yet and cause unexpected quick-fried spray, and the product safety performance is better.Four, relief valve is built in the dry-chemical fire extinguishing agent container, compact conformation, and it is little to take up room.Five, in having the scheme of axial quick-fried jet pipe, after this fire extinguisher is thrown in the scene of a fire, the mixture of carbon dioxide and powder extinguishing agent from fire extinguisher along two end axles to and the radially quick-fried spray in dry powder storage tank both sides and going out, have better fire extinguishing effect.
