Embodiment Construction

[0033] A metered injection compressed air foam fire extinguishing system and its application method of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as figure 1 As shown, a fire extinguishing system for measuring and injecting compressed air foam, the first part is the foam liquid supply part, which mainly consists of a foam liquid storage tank 1, a tuning fork sensor 2, a foam pump 3, a single-phase check valve 4, and a foam flow meter 5 , composed of 6 pneumatic three-way valves. The working state of the foam pump is controlled by the control system, and the speed of the foam 3 determines the mixing ratio of the foam mixture. After the ratio of the foam mixture is determined, the speed of the foam pump 3 changes with the flow of water. . The function of the tuning fork sensor 2 is mainly to monitor the storage capacity of the foam stock solution in the foam stock solution storag...

Abstract

The invention discloses a metering injection type compressed air foam fire extinguishing system and a using method thereof. The metering injection type compressed air foam fire extinguishing system comprises a control and power supply part, a foam liquid supply part, a water supply part, an air supply part and a foam mixing chamber and injection part. The invention further discloses a using method of the fire extinguishing system, reasonable mixing of air, a foam stock solution and water is systematically controlled, jet fire extinguishing of a foam mixed solution is carried out under a control system, and protection and pigging design is added. By means of the metering injection type compressed air foam fire extinguishing system and the using method, the reliability of the fire extinguishing system is improved through reasonable system design, foam mixing is conducted through a positive pressure type technology, the problem that the spraying range is short is solved, the control system is optimized, and the later maintenance efficiency and quality are improved due to the fact that modular design is adopted for a mechanical part.

Description

technical field [0001] The invention belongs to the technical field of power grid emergency fire extinguishing, and in particular relates to a fire extinguishing system for measuring and injecting compressed air foam, and also relates to a method for using the fire extinguishing system. Background technique [0002] Since entering the new century, human society has gradually entered the era of knowledge economy and network information. Slowly found that ensuring the safety and stable supply of electric energy plays a very important role in daily life, so the importance of the power grid is also increasing day by day. The transformer is an important part of the power grid to ensure the normal supply of electric energy. Once the transformer fails to work normally or a fire accident occurs, it will bring unpredictable losses to the local economic development. [0003] However, if a fire occurs in the transformer in the power grid, that is, the oil tank below is on fire, foam f...
