Extinguishant special for edible oil and preparation method of extinguishant

Abstract

The invention relates to an extinguishant special for edible oil. The extinguishant comprises potassium carbonate, sodium silicate, sodium chloride and glycerol. Simultaneously, the invention discloses a preparation method for the extinguishant special for the edible oil. The preparation method comprises the following steps of: mixing 570 kilograms of potassium carbonate, 390 kilograms of sodium silicate, 120 kilograms of sodium chloride and 300 kilograms of glycerol sequentially in a ratio, and dissolving in 1,560 kilograms of distilled water to obtain the extinguishant special for the edible oil. The extinguishant special for the edible oil comprises the main ingredients of the potassium carbonate, the sodium silicate, the sodium chloride and the glycerol, has an extinguishment function, and ensures that fire is not reburnt; and the extinguishant is sprayed into a hot oil pan to form thick foam by chemical reaction, so that burnt oil is isolated from air to achieve the effect of quick extinguishment. In addition, when the product is generated, a reactant can be more sufficient at constant temperature, so the fire-extinguishing efficiency of the product is higher.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to a special fire extinguishing agent for edible oil and a manufacturing method thereof. Background technique [0002] In recent years, with the widespread use of high-energy kitchen equipment and high-ignition edible oils, the threat of kitchen fires to people and property safety has increased. According to statistics, 50% of fires in hotels, restaurants and fast food restaurants are caused by kitchens, and mainly caused by liquid edible oil and grease. Kitchen fires are still the main cause of family fires. [0003] The reason why edible oil fires are difficult to extinguish mainly has two reasons: (1) the spontaneous ignition point temperature of edible oil is relatively high. Generally, the spontaneous ignition temperature of cooking oil is between 350 and 380 degrees, which is much higher than that of other flammable liquids. (2) After the edible oil is exti...

(2) After the edible oil is extinguished, it is easy to re-ignition

[0005] However, the fire extinguishing agent currently used in kitchen fire extinguishing devices generally has a spray coverage area that is not large enough to cover the entire oil surface; secondly, the fire extinguishing agent flow rate is not large enough to cut off the combustion chain or take away enough heat from the flame to extinguish the flame; , the injection power of the nozzle is not enough, it is difficult for the agent to penetrate the flame and reach the oil surface
