Intermittent atomization ejector and intermittent atomization ejecting system including same

Abstract

The invention relates to the technical field of ejectors and particularly relates to an intermittent atomization ejector. The intermittent atomization ejector comprises a liquid storage cylinder (1),a gas storage cylinder (2), an integrated valve (3) and an operation mechanism (4), wherein the water is stored in the liquid storage cylinder (1); high-pressure gas is stored in the gas storage cylinder (2); the integrated valve (3) comprises a main valve element (31), and the main valve element (31) can move between closing positions and opening positions of a gas outlet (21) of the main valve element (31) and a gas inlet (11) of the liquid storage cylinder (1); the operation mechanism (4) is used for controlling the opening of the integrated valve (3); and the main valve element (31) is located outside an airflow channel between the gas outlet (21) of the main valve element (31) and the gas inlet (11) of the liquid storage cylinder (1) in an opening position. The invention further provides an intermittent atomization ejecting system including the intermittent atomization ejector. According to the intermittent atomization ejector and the intermittent atomization ejecting system including the intermittent atomization ejector, liquid drops ejected from liquid storage cylinder have certain kinetic energy.

Description

technical field [0001] The invention relates to the technical field of injectors, in particular to an intermittent atomizing injector and a gap-type atomizing injection system with the same. Background technique [0002] When extinguishing a fire, water is the most ideal fire extinguishing agent, because it drenches on the burning part (fire stove) of the burning object to absorb the heat released when the burning object burns. In addition, compared with other fire extinguishing agents, it also has a phase change (The liquid phase changes to the gas phase) absorbs the most heat, and can also add a variety of synergists and other advantages. In the traditional fire extinguishing technology, the water sprayed on the combustible is to absorb the heat generated when the combustible burns, because the heat provides the energy and temperature necessary to maintain the combustion. Combustion must meet four conditions, that is, the existence of combustion, combustion-supporting sub...
