Solar energy and wind energy co-storing and co-using temperature adjustable boiler

The present invention utilizes topmost renewable energy solar energy and wind energy for the buried boiler of the temperature adjustable of thermal source, belongs to renewable energy utilization technology and heat energy utilization technology.

The present invention is the extension and the practical application of my another invention " electricity-heating conversion and co-storage and the continuous constant temperature utilization of light-electricity and wind-electricity " technology.Boiler is the consumption rich and influential family of fossil energy, and the annual mineral resources that consume are first of the various users.The air pollutants (flue dust, SOx, NOx, COx) that China's fuel produces account for 70% of all contaminants.Boiler is the main field of life of social concerns in the energy-saving and emission-reduction.The present invention can make the hot-water boiler of various uses and the non-renewable energy resources and the consumption of steam boiler reduce to zero, is the revolution of boiler technology, is the pith of energy revolution.

The present invention implements like this.Be total to two parts.Accompanying drawing 1 is that the electric heating conversion of photoelectricity and wind-powered electricity generation is store and heating facility together, and wherein left side figure is the vertical view of " U " shape Steel Tube Special, and the accompanying drawing right side is a side view.The 10th, the boiler position.In accompanying drawing 1, the present invention is embedded in Steel Tube Special underground, is thermal storage medium with gravel around the steel pipe; As electricity-thermoconverter spare, light-electricity or wind-electric current are when Steel Tube Special with Steel Tube Special, and the high resistance of this steel pipe makes electric energy convert heat energy to.Warmed-up steel pipe, be its inner air heat of flowing through, the thermal current that produces can be for any place (drying plant, high-temperature sterilization or digesting technoloy also can use for heating and multi-functional greenhouse, also can supply with temperature difference electricity generation device when no sunlight) that needs heat energy; Also, heat is stored in the outer medium of pipe for its pipe external space heating.Manage outer thermal storage medium, in that table soil is thicker but under the condition that the place is wider, available gravel and dry sand.Gravel is placed on the position of being close to the outer circle of steel pipe, and the gravel footpath is by big (〉 50mm) be placed on the steel pipe neighboring to little (about 2mm), outside the pebble stone periphery, stack dry sand (about particle diameter 1.5mm) through sorting.So placing gravel and sand, is for the hole of more connection is arranged between gravel, the sand particle.When steel pipe energising heat production, gravel and sand can with heat by tube edge pass to around, and intergranular air expanded by heating can flow to the farther underground space at faster speed, it passes the heat band at a distance.When the steel pipe no current, outer gravel of warmed-up pipe and air are to the tube wall heat supply, make the air medium (gravel, sand and air) outside managing in the pipe obtain heat, because the thermal capacity of sand, gravel is 3000-4000 times of air, so, within a certain period of time will be with identical temperature supply hot-air.At this moment, hot solids that steel pipe is outer and gas are the cold air heating that flows in the steel pipe, and steel pipe has become solid-gentle gas heat exchanger of gas again, and efficient is very high.For saving occupation of land and reducing buried depth, this Steel Tube Special can be made " U " font.Figure of description 1 (left side) is the vertical view of " U " shape steel pipe, and accompanying drawing 1 (right side) is a side view.1,2 is the vertical part of " U " shape steel pipe among the figure.1 is the steel pipe air inlet, and it is connected with the air pump of adjustable speed; It still is the binding post of wind-power electricity generation or photovoltaic generation.2 is the exhaust outlet of " U " shape steel pipe, and hot-air can send through it and pass the various thermal field institutes that use; It still is another binding post of wind-electricity or light-electricity output.As long as the place is enough big, the spacing of 1 and 2 pipeline sections is big as far as possible, and the big more storage heat energy of their spacing space is big more, and this storage heat is many more with the fate of thermic devices energy stable heating.The vertical length of 1 and 2 pipeline sections is got about 2m.3 is the horizontal component of " U " shape steel pipe.The total length of " U " shape steel pipe (i.e. 1---3---2) and its basal area size, the minimum electric energy of the output of Ying Yuguang-electricity and wind-electricity is complementary.4 is the gravel layer around the steel pipe.5 is the layer of sand that roughly waits particle diameter of gravel periphery.6 is ungarbled general sandy soil.7 is adiabator layer.8 is mattess, and its function is to prevent that hot-air runs off; Ground cracking even blast when preventing that thereby the overheated pressure of air is excessive; Prevent rainwater permeate the ground (this can make sand, gravel bed humidity, conduction).9 is spring loaded safety valve, and, volume of air too high when underground temperature expands, pressure increases before the design compression strength above mattess suddenly, and spring by compression and bleed.10 is insulation board (wall), prevents the short circuit between 1 and 2.When insulation is guaranteed, also can not establish this insulation board.

In the ocean or boat-carrying, or the place is narrow and small, or under the very thin condition of soil layer, buries " U " shape pipe and have any problem, and can change following embodiment (accompanying drawing 2) into: with a big drum 1 of armored concrete system (adding heat-insulation layer).Be full of the liquid thermal storage medium in it.Its top is by air pump 2 is housed.Efficient composite photo voltaic cell panel 3 (it is by the photoconduction piece of highly effective gathering sunshine, and---seeing solar energy facade highly effective gathering and comprehensive transmission technology for details, the patent No. 200610104321.1---and photovoltaic battery panel are formed) is arranged on it.4 is the coil pipe of special steel control.5 and 6 is its two ends.5 is air inlet, accepts the air by the air pump input, also is the binding post of power supply.6 is exhaust outlet, via it hot-air is delivered to the field of employment, also is another binding post of power supply.7 is wind-driven generator.Light-electricity and wind-electricity also are connected on 5 and 6, constitute a loop, and the electric current Steel Tube Special 5---4---6 of flowing through converts heat energy to, with the air heat in the steel pipe, and the also heating of the thermal storage medium outside steel pipe (storage heat).Very weak or when not having when wind-powered electricity generation or photoelectricity, the outer thermal storage medium of steel pipe by steel pipe to inner air tube heating (automatic reverse heat transfer).Thermal storage medium can be selected chemical stabilization for use, be heated and do not decompose, hundreds of degree centigrade also incombustible mineral oil.8 is temperature controller, and the real time temperature that it records according to the delivery temperature of setting with at exhaust outlet 6 poor adjusted the rotating speed of motor of air pump 2, and rotating speed is big, and the inner air tube flow velocity is big, and air heated time in coil pipe is few, and the air themperature of discharge descends; Rotating speed is little, and the air themperature of discharge rises.9 is solar storage battery, when no sunlight is also calm, is air pump power supply power by it.

Accompanying drawing 2 is store the thermal energy exchange facility of heat and water for gravel, it make in the accompanying drawing 1 the heat of storing continuously, controllably water is heated, be equivalent to the steam-boiler part in the conventional boiler.1 is steam-boiler (main body) in the accompanying drawing 2, and 2 is the outer assorted pot of steam-boiler (space is between the two used for cooling steam-boiler when steam-boiler overhauls), is welded by special steel plate.Another effect of steam-boiler overcoat 2 is the safety that guarantees whole facility district.Just in case steam-boiler 1 is because of accidental damages such as earthquakes, percolating water can only remain within the outer assorted pot, can be because of big water gaging does not permeate the ground in the gravel, and be subjected to high-temperature evaporation and explode.3 and 4 is the fixed screw of pot cover 14, and they are distributed with many along the steam-boiler limit makes pot cover 14 firmly on steam-boiler (the equal pressing force container of steam-boiler pot cover and fixed screw design strength).5 and 6 is pot cover 14 assorted pot circle fixed screws on every side outside.3,4,5,6 is again the binding post of photoelectricity and wind-powered electricity generation, when the underground heat not enough (running out of for the moment) of storing, when desiring to be eager to heat again, just insert external power supply (photoelectricity and wind-powered electricity generation, when not enough must the time also can insert the low ebb net), by steam-boiler and the direct heat production of outer assorted pot, 7 and 8 is inlet, outlets of temperature control coil pipe 12.9 and 10 is the inlet tube and outlet tube of outer assorted pot.11 is the outer filling pipe and the valve of steam-boiler, generally connects running water, and its adds steam temperature without interruption that water does not influence steam-boiler through the hot-air preheating between steam-boiler and the outer assorted pot.13 is hot water or steam (vapor) outlet.It also has thermal resistance thermometer except that valve is arranged, on-line measurement outlet steam temperature, and the difference that will export coolant-temperature gage and set water temperature degree is returned and is fed to steam-boiler filling pipe valve 11 moisturizing is increased and decreased.Reach the poor of outlet water temperature and set water temperature, be bordering on zero.This temperature difference feeds back to temperature control coil pipe air inlet (water) mouth 7 simultaneously, air inlet adjust in real time water (vapour) can make give vent to anger 8 go out vapour (water) temperature and the design temperature (production technology that has in full accord, have strictness to ask to temperature, available coil pipe 12 makes air outlet temperature accurately reach design temperature in real time.But to the not tight technology of temperature requirement, this coil pipe can).15 is the high strength anti firebrick, and its effect is to support the steam-boiler full weight; When steam-boiler will be lowered the temperature, it played a role in insulation, steam-boiler and outside space between the assorted pot when passing to Cryogenic air, steam-boiler stops to be heated from underground, thereby reaches (temperature that human body can bear) below 30 ℃ rapidly.11 and 13 valve all should be very big, and after their are dismantled, its cavity will be gone into pot as personnel and repair the hole.14 for covering the big pot cover of steam-boiler and outer assorted pot.

Solar energy and wind energy co-storing and co-using temperature adjustable boiler can be all technical process hot-water supply and steam of needing hot water and steam, be applicable to printing and dyeing, weaving, filature, papermaking, food processing fermentation and fields such as medicine and generating, there is not any pollution, can remove incrustation scale in the pot automatically, the performance of its strict control and design temperature is that traditional boiler plant is beyond one's reach.
