Abstract

The present invention relates to a tracing water quality stabilizer which is prepared by compounding a scale inhibitor, a corrosion inhibitor, a tracing polymer, an auxiliary agent, etc. The stabilizer has the characteristics of high efficiency, low toxicity and traceability. When the stabilizer is used in a water system to perform the function of corrosion inhibition and scale dispersion, the stabilizer can be used under the conditions of high hardness, high pH value and high weight concentration. When the stabilizer is used in a circulating cooling water system, the calcium hardness in the circulating water can reach from 750 to 1300 ppm (suppose the water-calcium hardness is supplemented by 120 ppm), the weight concentration can reach 10 times, and the stabilizer reaches the technical level of zero pollution discharge. When the stabilizer is matched with a correlation detection control instrument, automatic detection and control for medicament concentration and automatic medicament charge can be realized, so that the system operation is stable and economic. The tracking polymer used in the stabilizer is one of the components performing the functions of corrosion inhibition and scale dispersion in the compound medicament, and thus, the effective concentration of the compound medicament can be indicated exactly.

Description

A kind of spike type water quality stabilizer
One, technical field
The present invention be a kind of apply to rise in the water system scale inhibition disperses and high efficient tracing 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, background technology
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 it is few to reach the water conditioner of 6.0～10 times of cycles of concentration.
System moves under high concentration multiple, requires the control of water conditioner concentration more accurate, with result of use and the minimizing medicament unnecessary consumption of guaranteeing medicament.The ortho-water treatment agent can't carry out continuous detecting control with instrument, is difficult to accomplish accurate control.But spike type water quality stabilizer possesses the performance of continuous automatic inspection control, cooperates pertinent instruments, can make in the fluctuation of drug concentration maintains very among a small circle in the system.
