Description

A kind of environment-friendly type water quality stablizer
One, technical field
The present invention be a kind of apply to rise in the water system scale inhibition disperses and efficient and environment-friendly type water conditioner, the especially high concentration multiple of corrosion inhibition, high rigidity, high pH value condition under the water conditioner used of recirculating cooling water system.
Two, technical background
Cooling water system comprises heat exchanger, cooling tower, pump and cooling water pipeline.In the cooling water system operational process, the metallic surface of the heat exchanger that contacts with water coolant, pipeline, pump etc. can produce problems such as burn into fouling, sludge blockage, thereby influences the heat exchange efficiency of heat exchanger and service life of equipment etc.
Dirt in the cooling water system can have different dirts because of different systems.Dirt in the cooling water system generally has carbonate, phosphoric acid salt, silicate scale, metal oxide dirt, foundry loam and organic deposition, particularly carbonate scale and the foundry loam of calcium magnesium.Be high phosphorated with the water conditioner major part now, improper use can produce the phosphoric acid salt dirt deposition; The sewage of discharging is because of phosphorous too high polluting the environment.Dirt deposition can reduce heat exchange efficiency in the metallic surface.
The electrochemical action of the free metal ion in the water coolant and the oxygenizement of free oxygen can cause corrosion of metal and form the corrosion product dirt.Dirt deposition can form underdeposit corrosion in the metallic surface.
In order to slow down problems such as burn into fouling, sludgd deposition, in water coolant, add water conditioner usually, play the effect of corrosion-mitigation scale-inhibition dispersive, make cooling water system can be effectively, operation stably.
In recirculating cooling water system, in order to reach the purpose of high-level efficiency, low consumption operation, require recirculated cooling water moving than under the high concentration multiple, promptly reach at least more than 3.0 times, even reach 6.0~10 times zero blowdown level.
The water quality stabilizer kind that is used for water system at present is more, when using single anti-incrustation corrosion inhibitor, cooling water system is difficult at high concentration multiple, moves under the condition of high pH value, do not reach the purpose of equipment corrosion in the Controlling System, fouling, sludgd deposition, thereby influence the normal operation of system; Use composite water disposal agent, because of the difference of filling a prescription, result of use is widely different.General composite water disposal agent can reach 3.0 times cycles of concentration in recirculating cooling water system, but can reach 6.0~10 times of cycles of concentration, and environment amenable water conditioner is few.
The poly aspartic acid (PASP) of U.S. Donlar company development; Poly-amino-polyether base methylenephosphonic acid (PAPEMP) (" process water and the waste water " 2000 of Cagon company exploitation, " recirculated cooling water is handled the progress of new chemical agent " in 31 (6)) water treatment agent monomer, have efficient, environment amenable feature, but do not see the composite water disposal agent report identical with the present invention.
