Description
Technical field
The present invention relates to novel water-treatment medicament that uses in a kind of water coolant and the novel adding method thereof that is complementary with it.
Background technology
Water treatment agent is also referred to as water quality stabilizer.When being added in the cooling water system, can play effects such as inhibition, scale inhibition and sterilization algae removal to it, be to guarantee the systematic economy safe operation, saves the effective measure of the most normal utilization of the energy.
Existing water coolant water conditioner major part is a liquid solution, and small part is powdery or granular solid.The solid chemicals of the overwhelming majority is the simple mixing of a few solid material, and the range of application of these products is all quite narrow.Liquid preparation is of a great variety, can be made into the compound product that is suitable for various specified ranges.But, the effective ingredient in the liquid preparation is generally lower, and mostly between 5～20%, all the other are moisture.Therefore, the more packed weight of this class dosing big (general) with bucket or canned, more than the 20kg, trucking costs is higher, in addition, also leaks easily, during operation human body is becomed easily infected by etc.Because need allow medicament remain on liquid state,, also need larger area ventilation place simultaneously as storing ground so the temperature of storage at is had certain specialized range.These liquid products are all water-soluble entirely.When being added in the water, required time of uniform dissolution is very short.Add fashionablely when they are used as impact type, because factors such as windage loss and system's blowdowns, medicine residence time in system is shorter.Because the residence time of liquid medicine in cooling water system is shorter, guarantee the constant relatively difficulty of drug effect within a certain period of time.If any volume pump and automatic controlling system continuous dosing, then effect is just more satisfactory.Otherwise need a large amount of manpowers of cost, strict regularly frequent dispensing can keep certain effect.But, also expensive even fairly simple timing starts the volume pump administration device.More complicated a little the price of medicine system all surpasses the many middle-size and small-size systems medicament expense in 1 year usefulness usually.And volume pump and control system for adding drugs need frequent corrective maintenance could guarantee in a long time normally operation, and achieve the desired result.But but so further improved the cost of use of liquid product.Therefore, China uses most of system of liquid preparation to adopt regular impact type dosing mode to handle (frequency is for more than weekly) at present.
The weight of solid chemicals is all wanted much less than the liquid preparation of identical drug effect with consumption, thereby relative convenient aspect transportation and storage.But, because the dissolution rate of solid phase prod is slower, if directly render in the system, usually causes the part medicine not dissolve easily and produce fouling, reduce heat exchanger effectiveness and influence the normal circulation of water.In addition, granular medicament enters the work-ing life that system also can reduce water circulating pump.For fear of the generation of this class problem, usually need before use to add to system (please referring to Chinese patent 91200679) again after water-soluble with solid chemicals is complete in grug feeding jar.Doing has so but increased the use of medicament step, and solves the constant in time problem of maintenance drug effect.If the dissolution rate difference of each component of the solid chemicals that simply mixes is bigger, during then with its direct input coefficient, its result of use also will be greatly affected.In addition, solid chemicals easily generates dust, to operator's healthy regular meeting generation adverse influence.
