Description
Technical field
The invention belongs to fire-fighting equipment design field, especially belong to fire-extinguishing chemical mixing apparatus design field, particularly a kind of self contained adjustable proportion mixer for multiple extinguishing chemical.
Background technology
Froth fire extinguishing system has safe and reliable, economical and practical, fire-fighting efficiency high, especially has more outstanding superiority to category-B fire of putting out a fire to save life and property, and is the mode of putting out a fire to save life and property that oil fire is basic both at home and abroad at present.Foam proportioner is froth fire extinguishing system " nerve center ", and the quality of its service behaviour is directly connected to the success or failure that froth fire extinguishing system fights a fire.Foam proportioner has the types such as pressure air-foam proportioner, circular pump type foam proportioner, in-line foam concentrate inducer, electronic control type proportion mixer.
Pressure type foam proportioner is applied in ZP32 foam/Water spray automatic fire extinguishing system, low expansion foam extinguishing system, AFFF spraying fire-extinguishing system, is made up of water inlet pipe, drain pipe, mixing chamber, anemostat etc.Blender mainly utilizes venturi principle, during press water passing ratio blender, produce negative pressure differential therein and between foam solution basin, foam solution in basin is made to enter proportioner by the foam solution pipe be connected with proportioner, the orifice plate controlling foam solution flow is had, to form the foam of stable mixed proportion in tube connector---water mixed liquid.
Negative line pressure formula foam proportioner is mainly used in the ratio mixing of the equipment such as foam fire hydrant box, mobile foam cart.After press water enters proportioner from import, most of water sprays into anemostat at a high speed through nozzle, and between nozzle and anemostat, form negative pressuren zone, foam solution is inhaled into negative pressuren zone by liquid sucting port, enters anemostat with press water simultaneously, flows out from outlet; Flow out from exporting after the blended liquid phase that sub-fraction press water is then flowed out by control valve and anemostat in addition mixes.The handle (blender side) of turn control valve regulates the mixing ratio of mixed liquor.
Negative pressure pump proportioner is applied in suction type froth fire extinguishing system.Pump proportioner is made up of regulating handle, direction board, control valve, mixing chamber, anemostat etc.Blender is applicable to the foam solution of adapted 6%.Blender should be arranged near water pump, is connected with the outlet pipe of water pump and water inlet pipe.Blender requires that pump inlet pressure is less than 0.03MPa, otherwise will affect the absorption foam solution performance of blender.
Electronic control type proportion mixer, comprise water pump, foam inlet pipe, pump water inlet and drain pipe etc., the actual flow of water pump and foam dope is gathered respectively by water ga(u)ge and foam stream gauge, through controlling valve opening after micro computer process in microcomputerized control box, realize foam and water mixing under water pump different operating pressure, different output flow.
The problems such as above-mentioned each mixing arrangement respectively has advantages and disadvantages, and wherein the extinguishing chemical loss of momentum is comparatively large, mixed proportion control is difficult, installation cost is high exist all in various degree.Traditional proportioner, as adopted venturi principle, the pressure loss of main flow medium (water) can be made to reach more than 35%, and energy consumption is large.Traditional proportioner in use, (≤± 20% when larger change occurs for main pipeline flow and pressure), the liquid fraction precision sucked can reduce (Wu Cha≤± 30% greatly), control difficulty is large.Conditional electronic controls formula proportion mixer needs external electrical engineering cost high.
