Phosphate automatic dosing device process principle boiler feed water calcium and magnesium hardness can occur at high temperatures the chemical reaction, or the concentration of crystallization, to form insoluble scale, firmly attached to the boiler heating surface, this scale is a poor conductor of heat, will hinder heat conduction automatic dosing unit dosing equipment, serious accidents may occur boiler tube integrated automatic dosing device, in addition, will induce and exacerbate the dirt under the metal, chemical resistance, very serious harm. Although the boiler condensate, water went through a rigorous softening, desalination process, but there is still a small amount of calcium and magnesium hardness of water into the furnace, if not this part of the hardness of the treated scale will pose a threat to the safe operation of the boiler, at present, boiler water phosphate is the most appropriate treatment method, the reaction is as follows: 10Ca2 ++ 6P04 a + 2OH-- Ca, o (OH) 2 (PO4) 6 (dibasic calcium phosphate) dibasic calcium phosphate is a fluffy slag, easily with the boiler blowdown exclude automatic dosing device system, and does not stick in the pot becomes scale. Phosphate dosing device automatic workflow Overview This device includes four parts liquid solvent distribution system, metering dosing systems, security systems and control systems. Solid phosphate was added to the solution kits automatic dosing device, then, to add demineralized water or condensate water and stirred to dissolve, the metering dosing system was added to the boiler drum. Control can be manual dosing mode can also control signal based on the output of the host system, perform follow-up control, automatic dosing. Phosphate automatic dosing device suitable for high pressure range and higher Parameter Boiler water treatment.
