Binary channels Cooling and Heat Source haze purification heat-obtaining tower
Technical field
The binary channels Cooling and Heat Source haze purification heat-obtaining tower that type of the present invention relates to relates to the large field of China's new energy source energy-saving technology, environmental protection and resource two.
New energy source energy-saving environmental protection technology, technology by the horizontal cooling tower of efficient for summer open type and winter high performance fin coil heat exchanger heat source tower unite two into one, retain respective performance advantage by two air channel.Utilize summer solar energy to transform the psychrometric difference air energy independent air intake grid produced, external water body liquid film evaporation cooler improves cryocooled efficiency; Utilizing winter the built-in circulatory mediator of horizontal finned coil pipe to absorb the clammy air of haze can as the thermal source of heat pump, haze air is purified while heat-obtaining, and adopt independently air inlet to reduce air circuit resistance, white haze is removed by negative temperature accumulation of heat energy secondary diurnal periodicity, economic environment-friend substitution fossil energy, contrasting conventional air source heat pump winter utilizes the clammy thermal source ability in air to improve more than 90%, summer system external water body liquid film evaporation cooler contrast hot blast cooling refrigeration energy-conservation more than 50%.
Background technology
Along with the raising of people's living standard, the requirement of people to architectural environment is also more and more higher.Various refrigeration air-conditioner ventilates and heat supply process is promoted use day by day under construction, at current energy-saving low-carbon, reduce haze weather, under creating the large situation of ecocity, green ecological district, green low-carbon building, the low-carbon environment-friendly energy-saving heating mode that heat source tower is originated as heat pump cold (heat) source, plays key player in the development of people's productive life.But in longtime running project investigation display:
Conventional open type heat source tower directly forms the high efficiency of liquid film evaporation cooling in the tradition that summer retains at filling surface, but utilizing external circulation solution directly to absorb low level heat source at filling surface liquid film in the winter time, it is also more serious than Pollution of Boiler that matter melts process water capacity drift pollution corrosive environment metal.Utilize the clammy thermal source in frozen soln absorption air, solution is analysed wet dilution discharge and is caused certain water pollution, solution dilution causes solution concentration freezing point to rise simultaneously, source pump frost heave damage phenomenon often occurs, and the loss of solution year accounts for more than 20% of Winter heat supply operating cost, this mode is confined in larger southern air-conditioning system.
Novel closed type heat source tower also Shortcomings, utilize broadband low crammed Ji temperature difference finned tube exterior heat device by the circulating heat transfer to the clammy air of haze in the winter time, obtain the thermal source economic environmental protection of low level heat source as heat pump atmospheric environment to catharsis, do not have external circulation solution to the pollution of environment, frosting probability utilizes the energy in air to have dropped more than 90% than the highly dense fin heat pump of traditional large temperature difference.The unified clear white haze system of large-scale accumulation of heat energy can be designed as big-and-middle-sized closed type heat source tower, but still need configuration accumulation of heat clear white haze system can just seem loaded down with trivial details as middle-size and small-size system.Special Problems existing is in cooling in summer cooling procedure, need the meticulous maintenance of water treatment spraying and sprinkling evaporation cooling water being carried out to strict scale inhibition algae removal, once operation maintenance management is out of control, form jelly in incrustation scale+algae+air to cover finned tube surface and have a strong impact on heat-transfer effect and reach about 20%, lower cryocooled performance.
Thus solve and improve heat source tower heat pump technology, become in the medium and small architectural key applying heat source tower heat pump technical substitution fossil energy, technical requirement is the high efficiency that heat source tower should have the cooling of external filler spraying and sprinkling evaporation summer, the economic different transfer of heat in built-in circulation solution broadband low windage efficiency should be had winter, reduce while frosting probability raises the efficiency again, automatic clear white haze device should be had to realize atmospheric environment catharsis.
Summary of the invention
Type binary channels Cooling and Heat Source haze purification heat-obtaining tower object of the present invention.Be that closing low heat can blow in mouth summer, xeothermic circulating air enters water-cooled liquid film heat exchange layer surface by lower air intake grid and forms liquid film evaporation, leaving water temperature low raising cryocooled efficiency, removes drift moisture, through blower fan drive load and atmospheric air circulation by low heat finned heat exchanger; Be that opening low heat can blow in mouth winter, the clammy thermal source of haze is directly through low heat finned heat exchanger freezing absorption release low-temperature heat energy, under negative temperature weather conditions, remove white haze by can realize diurnal periodicity secondary to the accumulation of heat of thermal source (equipment absorb thermal source ability) 2%, obtain the thermal source of low level heat source as heat pump atmospheric environment to catharsis.
Contrast with conventional open type heat source tower, effectively can solve and absorb low level heat source winter, external circulation solution liquid-gas exchanges the matter process of melting and causes solution water capacity to be drifted about, contaminated environment corroding metal is than Pollution of Boiler also serious problems, and the loss of solution year accounts for more than 20% of Winter heat supply operating cost drops to lower than 2%, reach built-in circulation solution not dilute by heat-obtaining condensate water, solution concentration stablizes the security having ensured source pump.
Contrast with novel closed type heat source tower, low heat finned heat exchanger is not heat exchange in the effect in summer, but be the anti-layer that wafts of Water spray cooling, effectively can solve the recirculated cooling water of summer without water treatment in the evaporative cooling of finned tube surface spraying, form jelly in incrustation scale+algae+air to cover finned tube surface and have a strong impact on heat-transfer effect and reach about 20%, reduce cryocooled performance issue.
