Description
Technical field
The present invention relates to a kind of heat accumulating type cooling tower, is especially a kind of single tower many groups regenerative cycles switchover operation, direct heat-exchanging type cooling tower, is generally applied to electric power, oil, chemical industry, iron and steel, the industry-by-industry such as civilian, belongs to water-saving technology field.
Background technology
Cooling tower is essentially open type, cooling tower (also referred to as cooling tower) is atomize water into contacting of minute water drop and air as principle, what have also needs increase filler to increase the area contacted with air, the used heat left by water evaporation in recirculated water, the air of dry low enthalpy is after the twitch of blower fan, also the form of high tower can be adopted, utilize stack effect, enter in cooling tower from air inlet, the water natural seeding water system of damp and hot high enthalpy is spilled in tower, when water droplet contacts with air, on the one hand because air heat transfer coefficient is lower, on the other hand owing to there is pressure differential between water vapour surface and air, the high-temperature water molecule that saturated vapor partial pressure is large flows to the air that pressure is low, produce Evaporation Phenomenon under the effect of the pressure, by the stack effect of blower fan or cooling tower, the steam of air and atomization is got rid of from top, take away evaporation latent heat, heat in water is taken away i.e. evaporation heat transfer, also evaporation water has been taken away, thus reach the object of cooling, also have lost evaporation water.The device reaching this function is cooling tower, the kind of cooling tower is a lot, distinguish according to the structure of tower and air mobility status, there are cooling stack and the large class of mechanical-draft cooling tower two, according to air and the relative mobility status of water in tower, can be divided into reverse-flow and cross-flow type again, mechanical-draft cooling tower cooling effect is best, and recycle ratio is generally at 3 ~ 5 times.The effect of cooling tower is by atomization at tower for the cooling water of used heat of carrying under one's arms, atomized water fine drop filling surface in cooling tower carries out mass-and heat-transfer, owing to there is pressure differential between water vapour surface and air, produce Evaporation Phenomenon under the effect of the pressure, flow out with air and take away evaporation latent heat, heat in water is taken away i.e. evaporation heat transfer, also have the droplet water of partial materialization and air to carry out heat exchange, make used heat be transferred to air and spill in air together with the steam of evaporation.The water evaporating 1KG under normal pressure needs the evaporation latent heat of 600Kcal, namely evaporates centesimal water, makes remaining water reduce the water temperature of 6 DEG C, general industry design standard requires recirculated water circulating ratio 3 ~ 5, visible, circulating water needs the water of at substantial, causes water resource waste serious.
In addition, open pond and cooling tower, be exposed in atmospheric environment, when containing sand and dust in air, at this moment, open cooling tower system will wash or perhaps absorb and dissolve containing sand and dust in air, and cause the pollution of circulation, the immersion of sand and dust brings fouling in water circulation system problem, fouling causes thermal resistance to strengthen, destroy original heat-exchange system, need antiscale and Periodic scale removal, cause antiscale, scale removal consumption.
Open pond and cooling tower are recirculated water easy breed bacteria and algae at low ambient temperatures, need to add chemical reagent sterilization, algae removal, have had the consumption of chemical addition agent.
Serious along with atmosphere pollution, the deleterious acidic material in air also, in the atomization diabatic process of water, has carried out mass transfer, makes the sour gas in air dissolve in water, adds the corrosivity of recirculated water, cause the corrosion of pipe-line system and cooling device.
In a word, the method for current latent heat of vaporization evaporative cooling recirculated water and cooling tower, while causing waste water resource, also cause the problems of the structure of recirculated water, corrosivity, breed bacteria and algae.
On 05 27th, 2015 intellectual property newspapers, Duan Xiaoning carries out statistics with regard to IPC classification number belonging to global cooling tower technical patent and finds, the patent in cooling tower field, the whole world mainly concentrates on the improvement of cooling tower structure or parts, relates in the improvement of countercurrent flow, trickle cooler structure for strengthening the aspects such as improvement that the improvement of heat exchange, Liquid distribution, the improvement of circulation and collection, heat exchange or heat-transfer equipment control.This also illustrates the device that global cooling tower still adopts latent heat of vaporization method.
