Technical field
The utility model relates to vaporation-type cooling device technical field, especially, and the closed cooling tower that relates to a kind of good antiscale property and freeze.
Background technology
At present, the closed cooling tower of employing mainly is comprised of several large parts such as metal heat-exchange coil pipe, housing, spray equipment, blower fan, feeding spraying pump, dehydrator and water ponds.Its basic principle is that the heating agent fluid enters heat exchange coil by the heat exchange coil inlet header, by feeding spraying pump the water in the water pond is transported in the spray equipment, carries out spraying cooling water by spray equipment to heat exchange coil.Meanwhile, closed cooling tower housing outer air is under the effect of blower fan, enter in the tower, with shower water cooling heat transferring coil pipe, by the intensification of evaporation of water and air, together the heating agent fluid heat of heat exchange coil is taken away, namely the steam of evaporation and exhaust of hot air are in atmospheric environment, realize the cooling of heating agent fluid, through cooling, the heating agent fluid leaves closed cooling tower by the outlet header of heat exchange coil.
Day by day raising along with socioeconomic development and manufacturing technique requirent, demand to closed cooling tower is increasing, especially closed cooling tower can be widely used in the industry fields such as petrochemical industry, pharmacy, iron and steel, automobile, casting, electric power, food, so the efficient energy-saving of closed cooling tower will have very important meaning.But in actual applications, the closed cooling tower heat exchange coil mainly adopts metal material at present, therefore do not carry out in the situation of specially treated to cooling water and heating agent fluid, will obviously corrode heat exchange coil, greatly reduce simultaneously the service life of equipment, also expended a large amount of metal material resources simultaneously.
Especially under low temperature environment, present closed cooling tower uses and especially pays particular attention to, temperature at heat exchange coil is reduced to below the freezing point of heating agent fluid, it is solid-state to cause the heat exchange coil inner fluid to be solidified as, because expansion will be burst heat exchange coil, cause whole closed cooling tower not use, this kind closed cooling tower also is difficult to carry out the maintenance of heat exchange coil simultaneously.
Closed cooling tower is owing to be to carry out the exchange of heat by the evaporation of heat exchange coil moisture film with the heat exchange of air, Just because of this, the cooling water of open type directly contacts with the heat exchange coil surface with outside air, causes being easy to contact dirt at heat exchange coil, and accumulation.Cause the tubing thermal resistance of heat exchange coil to increase, reduced heat transfer effect.
The utility model content
For the problem of the existence that has closed cooling tower now, the purpose of this utility model is to provide a kind of antifreeze and icing high-efficient closed cooling tower.
In order to reach the purpose of above-mentioned utility model, the technical solution of the utility model realizes as follows: a kind of good antiscale property and the closed cooling tower that freezes, and it mainly is comprised of blower fan, housing, dehydrator, spray equipment, heat exchange coil, scale removal ring, heat exchange coil inlet header, heat exchange coil outlet header, water pond and feeding spraying pump; Wherein, described dehydrator, spray equipment and heat exchange coil are arranged in the housing from top to bottom successively, and water pond places housing bottom, communicate with the import of feeding spraying pump, and the shower water delivery side of pump connects spray equipment; Heat exchange coil inlet header and heat exchange coil outlet header all are fixed on outside the housing, and they link to each other with outlet with the import of heat exchange coil respectively; Each horizontal segment of the tubing of heat exchange coil is socketed several scale removal rings, and blower fan is fixed on case top.
Further, the burr in the annulus inboard forms described scale removal ring by annulus and radial arrangement.
Further, described heat exchange coil adopts nonmetallic materials to make, and described nonmetallic materials comprise polymer composite and modification heat-conductive composite material.
Further, described heat exchange coil adopts nonmetallic materials tubing cross section for circular or oval, and its inwall has interior low rib fin.
Further, described closed cooling tower can be reverse-flow closed cooling tower, cross-flow type closed cooling tower or hybrid closed cooling tower.
The beneficial effects of the utility model are: adopt nonmetallic materials tubing as heat exchange coil, particularly adopt polymer composite as heat exchange coil, effectively prevented on the one hand the possibility of freezing and bursting heat exchange coil under the low temperature condition, also obviously reduce the material usage of Housign support, this material heat expansion amount has also been slowed down the speed of fouling greatly with more by force around the property characteristics on the other hand.This good antiscale property and the closed cooling tower employing scale removal ring that freezes will greatly reduce the possibility of dirt fouling outside heat exchange coil, improve the heat transfer effect of equipment.Simultaneously heat exchange coil and being connected of collector are arranged on the closed cooling tower hull outside, are convenient to maintenance.This utility model has had the low-cost characteristics of closed cooling tower, also for the system that adopts this equipment reduces energy consumption, reduces maintenance cost; Be convenient to the characteristics such as maintenance.
