Device for preparing air aqueous foam in pneumatic mode

Abstract

The invention discloses a device for preparing air aqueous foam in a pneumatic mode. The device comprises an air compressor. The air compressor is connected with a gasbag and a 15-degree T-branch pipe through a T-branch pipe correspondingly. The gasbag is arranged in a foam liquid storage tank. A fourway pipe is connected to the bottom of the foam liquid storage tank. Outlets of the fourway pipe are connected with the bottom end of a water level indicator, the other inlet end of the 15-degree T-branch pipe and a liquid discharging pipe correspondingly. The upper portion of the water level indicator communicates with the upper end of the foam liquid storage tank. A regulating valve is arranged at the top end of the water level indicator. Foam liquid can be injected into the foam liquid storage tank through the regulation valve and a water level indicator pipe. The outlet end of the 15-degree T-branch pipe is connected with a mixer through a flange. The other end of the mixer is connected with a foam outlet pipe. The device can convert foam liquid into foam just through pneumatic pressure, and miniaturization and portability of the device for preparing air aqueous foam are achieved; the foam liquid can be used whenever being opened and can be used continuously; and the device is suitable for fire prevention and control of the production places, the living places and other places and has the wide application prospects and the social benefits.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to a device for preparing air-water foam in a pneumatic manner. Background technique [0002] The development of foam fire extinguishing technology first started in the United States in the 1910s. Subsequently, with the development of the surface chemical industry, the research on foam fire extinguishing technology has gradually been valued by experts and scholars at home and abroad, and has developed rapidly. In 1949, Brady published the first public reports on the properties of aqueous foams. In the 1950s, the United Kingdom, the former Soviet Union, the former West Germany, Japan and other countries successively carried out research work in this area and achieved certain results. In 1956, Jacobi and others publicly reported the application of water-based foam to fire protection for the first time. fire practice. In the mid-1960s and 1970s, the United States, the...

Problems solved by technology

The three-power system is easy to achieve quantitative control, but the system has too many power sources, which makes it inconvenient to use and poses a great safety hazard

[0005] Air water-based foam technology has played a positive role in fire prevention and control, but because its preparation devices mostly use three-power or double-power, the process is complex, the maintenance and inspection process is relatively cumbersome, and it is inconvenient to apply on-site, it is difficult to promote the development of foam technology. popular application
