Description

A kind of cold water process equipment

Technical field

This utility model is related to water process, and in particular to a kind of cold water process equipment.

Background technology

The circulating water treatment of air conditioning cooling water system is always people's arguement and the problem inquired into.Current present status in China:① Do not processed or taken simply blowdown to control fouling or corrosion；2. supplementary water is carried out softening to control cooling water water Matter；3. cooling water system is set up electrostatic water treating device and comes antiscale, scale removal, sterilization and algae removal；4. medicine is added in cooling water system Agent (scale inhibition, inhibition, sterilization, algae removal) come control fouling, corrosion and microorganism breeding.

According to statistics, performance of refrigerant systems is caused to decline even shutdown as cooling water quality is unqualified also not rarely seen.State Outer research is early it has been discovered that containing substantial amounts of Legionella bacteria in central air-conditioner cooling water and easily logical in the way of water smoke, the globule Air borne is crossed, is endangered very important.In addition, extensively, south, northern water quality are also different, and having must for South China backlands domain span Different water process modes to be adopted for different territorial environments, find a kind of cold water process more suitably, more economical And control program.

1. cooling water quality standard

The cooling water system of central air conditioner system is by condenser, cooling tower, cooling pump, cooling water pipeline and filter etc. Composition.The water standard of open cooling water system should be according to the version of cooling tower, material, operating mode, dirtiness resistance value, corrosion The combined factors such as rate and the water treatment formula that adopted determine.To improve cooling water quality, it is necessary to arrange effective on pipeline Water-quality control and processing meanss.Open type cold water process water quality has to comply with《Code for design of industrial recirculating cooling water treatment》 (GB500050) requirement [3] and about specification to water quality.As open cooling water system can occur a certain amount of evaporation and float The loss of ease, so regular or automatic water supplement (rate of water make-up generally 1.2%～1.6%).The water quality requirement of cooling water replenishment, one As (being shown in Table 1) also higher than the requirement of cooling water quality.

The water standard of 1 central air-conditioner cooling water of table and make-up water

As can be seen from Table 1, several indexs of cooling water quality than quality of groundwater standard (GB/T14848293) II Class standard is taller, and the water standard of make-up water has been even up to I class standard, and it is that comparison is high to illustrate that quality of cooling water is required. If directly with subsoil water as cooling water, subsoil water water temperature due to relatively low and stable, although therefore can energy-conservation, cooling water The sealing factor for making condenser is increased by high rigidity, and in the case where amount of cooling water is constant, the water yield of cooling tower process can increase on the contrary Greatly.

2. the problem that cooling water system is present

2.1 fouling

Cooling water replenishment typically adopts tap water, some units to adopt phreatic water, either tap water still for energy-conservation Well water, has certain hardness.If well water, hardness can be some higher.In addition, the water source common source of southern area in or Through limestone rock stratum, so hardness of water can be higher than the north.It is water that cooling water system produces another reason of fouling Temperature is dynamic change, particularly in load fluctuation than in the case of larger, the change of water temperature can accelerate the formation of incrustation scale.Hardness After very high cooling water running for a period of time, a large amount of incrustation scales can be produced in condenser heat exchange copper tube or in water pipe, this is mainly Caused by there is following reaction in the calcium bicarbonate in water.

In order to prevent cooling water, it is at present many using electronic processing methods (include Electrostatic Treatment, em polarization, High-frequency electric field magnetization etc.).However, when to the unreasonable of the installation number and position design of water mangetizer, can be to water system Heavy corrosion is produced, and this negative effect is far longer than positive effect, serious harm is caused to air-conditioning equipment and water system.Such as The full import central air-conditioning on the Jiao great Shen Tong squares of 30 floor height of Shanghai, design department designs in water system and is mounted with about more than 10 Platform electromagnetic water treating device, does not take other method for treating water again in operation.Equipment has only run a year and a half and has just generated seriously Corrosion.Jing chemically examines water sample, and in water, Cu2+ ion concentrations are up to 50mg/L, and Fe2+ is up to 200mg/L.

2.2 corrosion

Belong to electrochemical corrosion more the corrosion that cooling water system occurs, affect condenser or the factor of inner-walls of duct corrosion to have The dissolved oxygen of water, pH value, each ion concentration etc..

The Fe (OH) 3 generated by negative and positive polarization response is exactly usual generated rust, and the ferrum typically visually seen Rust is Fe2O3nH2O, is also hydrous ferric oxide.If the condenser in cooling water system is copper pipe, when Cu2 is there are in water + when, even if its concentration in water is very low, but it is the depolarizing agent of cathode reaction, thus corrosion is had and significantly promotes to make With.

With the increase of Cu2+ concentration, corrosion reaction aggravation, Copper Tube Corrosion is finally made to bore a hole.Generally, if plus Enter corrosion inhibiter (passivator), or by Electromagnetic Treatment, can be to solve the problems, such as what is corroded, that is, the problem corroded is nor very tight Weight.

2.3 sludge and algae

As cooling water temperature is suitable, substantial amounts of antibacterial, microorganism and algae are easily grown.At present, many handpiece Water Chilling Units The dirt separator installed all is y-type filter, is mounted on the standpipe before cooling water pump entrance.This y-type filter, can only catch The building waste of equipment initial operating stage, prevents these rubbish from entering condenser, can not catch in day-to-day operation tiny incrustation scale and Rust deposite, therefore condenser dirty, deposition and other impurities can be caused.In addition, the central air-conditioner cooling water system of current many units System lowest point is all fitted without quick draining valves, and fractional unit has also clogged these sewage draining exits with closure, and this way is in fact Mistake, accumulated sludge and impurity in refrigeration unit are easily made, heat exchanger effectiveness is affected.The cooling water system of all employing electromagnetic water treatments System, will install blow-off line, carry out continuous blowdown, and blowdown flow rate can be controlled in 0.5%～1.0% of quantity of circulating water or so.Open Formula recirculating cooling water system, need arrange filter, the filter capacity of filter, according to situations such as the dustiness of local air, It is contemplated that by quantity of circulating water 1%～5% or with reference to practical situation selecting, to obtain preferable treatment effect.It is new to other The cooling water system of installation or the cooling water system of scale removal completely, it is also possible to per blowdown in 1～2 week once.

It is known that cooling water system is the important component part of large-size air conditioning cooling water system.The circulation for keeping qualified is cold But water water quality is extremely important, therefore is worth causing the great attention of person skilled.Traditional drug treatment regimes technology is multiple Miscellaneous, environmental pollution is big, brings certain difficulty to person skilled, and is not easy to realization and automatically controls.So being badly in need of research and development Go out a set of water treatment facilities for being specifically designed for air conditioning cooling water system.
