Embodiment 1

[0010] a. Preparation of fire extinguishing agent

[0011] Add 670-690 liters of deionized water into a solution reactor with a volume of 1000 liters equipped with a stirrer, and under the condition of maintaining normal temperature (20-30°C), add 76.0kg of potassium chloride (23wt.%) solid into the reactor , start stirring until it is completely dissolved, add 171.0kg of ammonium carbonate (52wt.%) solid into the reactor, stir and dissolve completely, then add 82.0kg of disodium hydrogen phosphate (25wt.%) into the reactor. After complete dissolution, a fire extinguishing solution with a specific gravity of about 1.1 is obtained. Then store the fire extinguishing solution in a closed, light-proof bottle. Before extinguishing the fire, dilute the fire extinguishing solution at a ratio of 1:20 to obtain the fire extinguishing agent. Fill the fire extinguishing agent into the fine water mist fire extinguisher to extinguish the fire.

[0012] b. Fire extinguishing test results ...

Embodiment 2

[0018] The weight and specific gravity of ammonium carbonate and disodium hydrogen phosphate are adjusted to 184.0kg ammonium carbonate (56wt.%), 69.0kg disodium hydrogen phosphate (21wt.%), and all the other are prepared according to the same method as in Example 1.

Embodiment 3

[0020] The weight and specific gravity of ammonium carbonate and disodium hydrogen phosphate are adjusted to 207.0kg ammonium carbonate (63wt.%), 46.0kg disodium hydrogen phosphate (14wt.%), all the other are prepared according to the same method as in Example 1.

Abstract

The invention discloses a power transmission line forest fire extinguishing agent. According to the invention, 23wt% of potassium chloride, 52-65wt% of ammonium carbonate and 12-25wt% of disodium hydrogen phosphate chemical solid are sequentially and respectively dissolved in an appropriate amount of water, and thus a fire extinguishing fluid having the specific gravity of 1.1-1.2 can be obtained; the fire extinguishing fluid is stored in a sealed lightproof container. Before, the power transmission line forest fire is put out, the fire extinguishing fluid is diluted by using water in a ratio of 1:20 and then the diluted fire extinguishing fluid is filled in a water mist fire extinguisher; the fire extinguishing agent is sprayed to the scene of fire as the water mist to put out the fire. The power transmission line forest fire extinguishing agent is quick in fire extinguishing speed, high in fire resistance and high in fire extinguishing efficiency; a small amount of fire extinguishing agent is capable of effectively extinguishing the forest fire of a certain area and effectively preventing a transmission line from tripping due to the forest fire.

Description

technical field [0001] The invention relates to a fire extinguishing agent, in particular to a power transmission line mountain fire fire extinguishing agent. Background technique [0002] In recent years, mountain fires have occurred frequently on transmission lines, and the operation of transmission lines has been seriously threatened. Extinguishing the fire near the transmission line at the initial stage is an effective means to ensure that the transmission line is not affected by the fire. The fire extinguishing ability and efficiency of the fire extinguishing agent composed of chemical reagents are much greater than that of ordinary water. On the other hand, the location where the mountain fire occurs is inconvenient, and it is difficult for ordinary vehicles to get close to the fire scene. The fire extinguishing method using water as a fire extinguishing agent consumes a lot of water and is not suitable for power transmission line mountain fires. Therefore, there is ...
