Abstract
The invention discloses a cooling agent for a hot-gas sol extinguishing agent. The cooling agent is prepared from the following components in parts by weight: 50-65 parts of carbonate, 30-48 parts of metallic oxide and 1-5 parts of sulphate. By adopting the cooling agent disclosed by the invention, the temperature when aerosol passes through an exhaust nozzle can be effectively reduced, thus the cooling effect is ideal; and the cooling agent disclosed by the invention is non-toxic and harmless and is green to use.
Description
Technical field
The invention belongs to the extinction using gas technical field in fire prevention, relate to a kind of refrigerant that reduces hot-gas sol fire extinguishing agent reaction and gas outlet temperature.
Background technology
The aerosol-type fire-fighting medium is a class fire-fighting medium of recently developing in the fire extinguishing field, and it forms aerosol product by the fuel in the flame fire-fighting medium, thereby reaches the fire extinguishing purpose.Aerosol extinguishing agent can discharge a large amount of heats during by flame, for fear of the generation of spot fire, must carry out cooling to fire-fighting medium.By chemical coolant, hot aerosol to be carried out chemical cooling for one of main method of cooling of hot-gas sol fire extinguishing agent at present.Yet the component of existing chemical coolant and formula are not all very desirable, and the temperature of hot aerosol that causes spraying spout is still very high, easily causes the secondary resume combustion; And existing chemical coolant toxicity is stronger, uses and not only can cause personnel's injury also can cause contaminate environment.
Summary of the invention
The refrigerant that provides a kind of hot-gas sol fire extinguishing agent to use is provided technical problem to be solved by this invention.The present invention can effectively reduce aerosol by the temperature of spout, and cooling performance is ideal; And the present invention is nontoxic, uses environmental protection.
For solving the problems of the technologies described above, technical scheme of the present invention is as follows: the refrigerant that hot-gas sol fire extinguishing agent is used, this refrigerant adopts 1～5 part, 50～65 parts, carbonate, 30～48 parts of metal oxides and vitriol to make by mass parts.
In above-mentioned refrigerant, this refrigerant adopts 2 parts, 58 parts, carbonate, 40 parts of metal oxides and vitriol to make by mass parts.
In aforesaid refrigerant, described carbonate is to get wherein two kinds or three kinds of proportionings compositions in these three kinds of raw materials of zinc carbonate, calcium carbonate and magnesiumcarbonate.
In aforesaid refrigerant, described carbonate is to get zinc carbonate, calcium carbonate and three kinds of raw materials of magnesiumcarbonate, and mass percent is;
Zinc carbonate: 15～30%;
Magnesiumcarbonate: 45～60%;
Calcium carbonate: 10～25%.
In aforesaid refrigerant, described carbonate is to get zinc carbonate, calcium carbonate and three kinds of raw materials of magnesiumcarbonate, and mass percent is;
Zinc carbonate: 20～25%;
Magnesiumcarbonate: 50～55%;
Calcium carbonate: 20～25%.
In aforesaid refrigerant, described metal oxide is magnesium oxide, calcium oxide, zinc oxide or get wherein two kinds or three kinds of proportioning composition mixtures in these three kinds of raw materials of magnesium oxide, calcium oxide and zinc oxide.
Beneficial effect of the present invention: the present invention is by improving component and filling a prescription and can effectively reduce aerosol by the temperature of spout, test through the applicant, the reacted temperature of hot aerosol is up to 1000 degrees centigrade, temperature through the cooling after heat aerosol ejection of the present invention spout can drop to below 150 degrees centigrade, cooling efficient is ideal, has avoided the scene of fire that the possibility of secondary combustion occurs.Meanwhile the present invention is nontoxic, low-carbon environment-friendly, has superior social benefit.
The present invention is further illustrated below in conjunction with embodiment.
