Description
Technical field
The present invention relates to a kind of cooling tower, particularly a kind of subdivision water saving fog dispersal enclosed is coolingTower.
Background technology
In recent years, because raising and the evaporative type cooler/closed of manufacturing technique requirent are coolingThe gradual perfection of the performance of tower own, the domestic demand to such tower-type equipment increases very fastSpeed, in industries such as electronics, power plant, casting, food, chemical industry, buildings, oneself has more widelyApplication, and customer volume and related industry face are in continuous expansion. Evaporative type cooler and airtightFormula cooling tower is two kinds of different calls of same class product substantially, is and in pipe, walks process flowOutside body, pipe, take away tube fluid heat by shower water evaporation, and take away steaming by strong-force exhaust modeSend out a kind of cooling device of latent heat.
In the industry projects such as built power plant, petrochemical industry, papermaking, metallurgy, the overwhelming majority followsRing cooling water system adopts open system, and capital equipment is traditional wet cooling tower. The typeThe supplementing water of recirculating cooling water system in full factory fresh water consumption proportion up to 60% withOn. A large-scale iron company is as Shoudu Iron and Steel Co, or a large-scale chemical enterprise is as 4,000,000,000m3/ a coal preparing natural gas project, the scale of its circulating water cooling tower is approximately 200,000 m3/ h, itsRate of water make-up is 2% left and right. During the normal driving of project, within every 2 days, cooling tower is arranged in airThe steam of putting is approximately 150,000 tons, forms mist.
Tradition closed cooling tower, water-spray system and water cooling coil pipe are interconnected, and needCooling hot water is through water cooling coil pipe, as a kind of mediate contact formula cooling tower, common coolingThe filler of tower is substituted by heat exchange coil group; Service object is mainly that some are wanted cooling water cleannesAsk higher, or coolant water temperature control required precision is higher, is unsuitable for adopting common open cooling towerApplication scenario form moisture film or water droplet. Extraneous cold dry air from bottom to top or level through dishPipe, carries out heat exchange with outside tube water film or cooling coil, and air is heated and humidification, mixesAfter discharge tower from tower top with hot and humid air. , rainy season lower in morning and evening temperature, winter andIn the season that humidity is larger, go out the dew point of tower damp-heat air apparently higher than outside air temperature, dischargesCondensation when tower is outer and produce a lot of globules, has produced white mist; Cause in the humidity in lower wind direction areaRise, white mist drops on ground and causes cooling tower around road surface is wet and slippery, affect staff normallyPatrol and examine; Form icing winter in severe cold area, also have near high-voltage line, equipment and buildingBad impact, for example, freeze and short circuit etc. Main when the work of tradition enclosed dry-and wet-type cooling towerWalk heat by evaporator strip, then extracted out outside tower by the blower fan that runs up. Therefore moved at cooling towerCheng Zhong, a large amount of water are consumed, and need constantly to supplement a large amount of fresh waters, the water expending moneySource is more.
Summary of the invention
For the deficiencies in the prior art, the object of the invention is for a kind of subdivision water saving is providedFog dispersal closed cooling tower, this cooling tower can reach the effect of fog dispersal, has water-saving result simultaneouslyGood feature.
