Description
Technical field
The utility model relates to central authorities' washing unit technical field, is specifically related to a kind of central air-conditioning filtering system.
Background technology
At present, in the circulating water system of central air-conditioning, easily cause the adverse consequencess such as system fouling, burn into biological clay and bacterium algae grow due to water quality instability. Center air-condition circle water is running in working cycle, and the corresponding increase of the concentration of various salt, when Cl and SO4 ionic concn is higher, can make the antiseptic property of metallic surface protective membrane reduce. Especially the ionic radius of Cl is little, penetrance is strong, it is easy to the protective membrane destroying metallic surface increases the anodic process speed of its corrosion reaction, causes the local corrosion of metal. In water, growing of microorganism also can produce bacillary corrosion, such as sulfatereducting bacteria, iron bacteria etc.
In central air-conditioning recirculating cooling water system, the hydrocarbonate concentration dissolved increases along with evaporation concentration, when its concentration reaches capacity state, or when making water temperature raise through heat exchanger heat transfer surface, in water, salt dissolution equilibrium is destroyed, the generation of following reaction and incrustation scale can occur, and heat conductivility is very poor, seriously affects heat exchange efficiency. The main material of central air conditioning water system equipment, pipeline is carbon steel, and the hydrate of its corrosion product mainly oxide compound of oxyhydroxide and iron, in colloidal state, is suspended in water stablely, but when by during heat exchanger easily in the mutual aggegation precipitation of heating surface colloid. The Fe2O3 of precipitation is due to its discontinuity and leakiness to metal without provide protection, and the magnetic due to it, clinging power is strong, and than great, eliminates difficulty, forms dirt. Microorganism can be divided into bacterium, fungi and algae, and owing to it is dispersed in each corner of nature, and the temperature of center air-condition circle water, salt, pH value, dissolved oxygen etc. are relatively applicable to microbial reproduction. If failing to be effectively controlled, microorganism constantly grows, and secretes a large amount of mucus, insoluble impurities in water is bonded together, produce the internal surface that foundry loam is attached to e-quipment and pipe, hinder the flowing of water and system thermal to exchange, and often cause underdeposit corrosion in Stickydeposit place.These threes such as above-mentioned incrustation scale, corrosion and microbial growth are not isolated, contact mutually and influence each other, and together with incrustation scale is often combined in dirt, fouling and biological clay can cause again or add heavy corrosion. These incrustation scales, erosion and biological clay bring serious harm to the safe operation of central air-conditioning. Equipment pipe incrustation scale adheres to: the thermal conductivity of incrustation scale is extremely low; reduce heat transfer efficiency or conduct heat not even; affect the refrigeration of central air-conditioning; condenser pressure is raised; increase the positive backside pressure of compressor poor, cause motor load to increase, cause high-voltage operation; increase power consumption, time serious, can directly cause main frame high pressure force outage. Make system water internal circulating load reduce settling, cover central air conditioning water system equipment pipe or interchanger runner surface such as incrustation scale, microorganism viscosity mud, serious in blocking pipe, hinder water flowing, refrigerated water internal circulating load is reduced, heat exchanger effectiveness reduces further. System pipeline and equipment inner wall often cause anvil cinder to come off because of corrosion, and the anvil cinder come off can block coil pipe, and air-conditioning heat exchange effect is declined, and cause perforation leakage to wait significant outages accident time serious; The existence simultaneously corroded also makes shorten dramatically the work-ing life of equipment. In order to prevent the formation of incrustation scale, the corrosion of operating device and pipeline, improve heat exchanger effectiveness, save energy, in the work-ing life of extension device, just must process and daily Handling of Stabilizing Water Quality central authorities' air-conditioner circulating water system, to reduce the corrosion of e-quipment and pipe, control fouling generates, and suppresses microorganism procreation, ensures that system normal safe runs.
