Description

A kind of white carbon black-CNT solar absorption agent for being applied to solar water heater
Technical field
The invention belongs to solar water heater heat-collecting system regions, more particularly to a kind of charcoal for being applied to solar water heater Black-CNT solar absorption agent.
Background technology
At present, as " energy-conserving and environment-protective " theory is progressively deep in the minds of people, the clean energy resource as solar energy is got over More to be welcome by everybody, wherein very popular solar water heater just illustrates this point well.Solar water Device is that solar energy can be converted into heat energy by one kind, and water is heated to high-temperature from low temperature, to meet people in life, life The equipment of the hot water demand in product.On market, common water heater is divided into according to version:Vacuum pipe solar water heater And flat solar water heater.What is be most widely used at home at present is vacuum pipe solar aqueous vapor device, and international Upper is typically all that flat solar water heater application is more.Vacuum pipe solar water heater be by:Heat collector, heat accumulation The part such as bucket, water pipe, support and accessory constitutes.Vacuum tube is the core component of vacuum heat-collecting gas, is whole solar energy system Electromotor.Its good and bad performance directly determines performance and the life-span of solar energy system.Fine vacuum is pumped between glass inside and outside pipe, is made Convection current and conductive heat loss are preferably minimized.Efficient Al-N/Al heat absorbing coatings vacuum tube collection is adopted current solar water heater more The solar radiation of absorption, with high solar absorptance and low transmitting ratio coating, is converted into heat energy by hot device;Using cold water proportion The characteristics of more than hot water proportion, formed in the vacuum collector cold water from top to bottom, hot water water circulation from bottom to top, pass through Such circulation, gradually rises the water temperature in attemperater.As the vacuum interlayer of vacuum heat collection pipe has good insulation Performance, cylinder heat-sink shell have nature tracing property to the sun, as long as therefore have solar radiation vacuum heat collection pipe just work, Even if in high cryogenic region, also normally can run throughout the year.But, as vacuum tube solar heating element is by some vacuum Pipe composition, gap is there is between pipe, when solar irradiation is mapped on substrate, some solar radiation has been irradiated to two Interstitial site between vacuum tube, this is a part of invalid energy for collecting system, is only irradiated on vacuum tube Sunlight could effectively by heat collector institute sorption enhanced be heat energy.So effective absorbing area is little, sun absorption rate is not It is too a height of 60% or so.Meanwhile, vacuum tube inboard wall outer surface is plated using technologies such as fine vacuum evaporation reaction, magnetron sputterings Selective absorber coating with excellent long-time stability, but this technology floating coat technics comparing is complicated, it is relatively costly.It is flat Plate solar water heater is mainly made up of the part such as flat plate collector, storage tank, water pipe, support and accessory, its middle plateform collection Hot device is the critical component of flat plate solar water heater, and its hot property height is the important indicator for weighing water heater quality.Have The higher thermal efficiency.For solar vacuum-tube water heater, flat-plate solar collector is but a continuous plane, Whole heat collector surface can receive sunlight.So, under identical daylighting area and intensity of sunshine, flat solar The mean daily discharge of hydrophone is typically higher than solar vacuum-tube water heater mean daily discharge more than 6%.With good pressure-bearing Performance.Stable performance when constituting big system.But flat solar water heater has some shortcomings, flat plate solar water heater Version core is not vacuum, effect of heat insulation be not it is fine, self-radiating than larger, compared to vacuum pipe solar, its winter radiating compared with Hurry up.As its installation needs full copper pipe connection, internal structure to be also copper piece, so from for cost and installation, early investment It is bigger than vacuum tube.Patented technology " the solar energy absorbing paint " (patent No. of Xi'an Li'ao Technology Co., Ltd. 2010106238566, application publication number CN 102134428A) in disclose a kind of for solar energy (light) is transformed into heat energy Solar energy absorbing paint, it provide three kinds of solar selectively absorbing coatings, the coating is by resin, absorbent, body constitution face Material, auxiliary agent and solvent are formulated, and coating color is formed by various absorbent (pigment) compounding, and the major function of coating is Solar energy is converted into heat energy, and with certain dicoration, coating color is brownish red, bottle green and black, and coating is to too The absorptance of sunlight is 0.95.But absorbing coating is still applied to vacuum tube wall coating by this invention, to collecting system Configuration aspects do not improve, still the utilization rate of the solar energy with vacuum tube type water heater is low and cost high, and technique is multiple Miscellaneous shortcoming.Patented technology " solar energy heat absorbing the material " (patent No. that Wuhu Chenxi New Building Materials Technology Co., Ltd. possesses 2015103912598, application publication number CN 105038551A) in disclose solar energy heat absorbing material, including with resin, solidification Agent, absorbent, solvent, auxiliary agent, absorption enhancer, they are by adding bromo- 2- (2- the fluorophenyls) -1- rings third of 2- in coating Base ethyl ketone, forms optical trap trapping agent with resin, absorbent, can reach 96-96.5%, emissivity to the absorbance of solar energy For 0.2-0.25.But this patent principally falls into the solar energy heat absorbing material for flat plate collector.Still in structure also It is the self shortcoming that there is flat plate collector.Heat absorption efficiency is high, but radiating, than larger, effect of heat insulation is poor.
In sum, on domestic market, vacuum tube type water heater is little to the effective absorbing area of sunlight, identical Daylighting area and intensity of sunshine under, solar vacuum-tube water heater to sunlight absorption rate be only 60% or so;In glass The technologies such as fine vacuum evaporation reaction, magnetron sputtering are adopted to plate the selection with excellent long-time stability on glass inner tube outer surface Absorber coatings, thin film or coating process it is more complicated, it is relatively costly.
