Foam solution output: mainly comprise foam liquid tank, enter in foam liquid tank with the partially communicating appendix of aerogenesis by the bottom of foam liquid tank, and the port of export of appendix is higher than foam solution, the upper end of foam liquid tank is provided with the interpolation foam solution entrance that doubles as exhaust outlet, entrance is provided with control valve, the upper end of foam liquid tank is provided with the discharging tube of a sealing simultaneously, the lower end of discharging tube is immersed in foam solution, the discharging tube other end is connected with flexible pipe by valve orchid, and the other end of flexible pipe is connected with the feed liquor one end of the three-way pipe producing bubble part;
Produce bubble part: be made up of three-way pipe, one end of three-way pipe is connected with another port of export of air compressor by control valve, and the other end of three-way pipe is connected with the flexible pipe of foam solution output, and the 3rd end of three-way pipe is foam delivery outlet.
 
advantage of the present invention and beneficial effect:
The application apparatus for the preparation of aqueous foam using gas as sole power provided by the invention, be a kind of Compressed Gas utilizing air compressor to produce as sole power, foam solution is changed into the system bubble technology of aqueous foam.
The present invention utilizes air compressor as sole power.Air is inputted foam solution fluid reservoir by the port of export of air compressor, by increasing the pressure in foam fluid reservoir, utilizing pressure reduction that foam solution is exported fluid reservoir by the woven hose stretched in foam solution, and being sent in three-way pipe by foam solution by flexible pipe.Another port of export of air compressor is connected with the one end of the three-way pipe producing bubble part, and high-speed gas and foam solution form foam at the outlet section of three-way pipe by turbulent closure scheme, from foam outlet foam output.
The present invention also can be the dust Control in the larger place of the dust-producing amounts such as harbour bulk goods dust prevention and control, cement plant, thermal power plant, bursting work and structural fire protection and there is the ignition point of spontaneous combustion, there is provided the technique for applying of aqueous foam technology, the present invention has very wide application prospect and social benefit.
