A kind of multifunction energy-saving heat storage can of solar heating system

Affiliated technical field

The utility model relates to a kind of multifunction energy-saving heat storage can of solar heating system, belongs to the solar heating technical field.

Background technology

At present, solar heating technology has entered the substantive application stage.Adopt shortage of heat in order to tackle the cloudy day, more solar heating system has all adopted electric auxiliary heating heat storage can, has solved the problem of cloudy heat supply deficiency preferably.But, because the heat storage can capacity of each solar heating system is little then one or two ton, greatly then five or six tons even tens tons, if the electric-heating technology misapplication will cause the huge waste of electric energy.This is because the auxiliary heating of present electricity heat storage can, all be bottom or the bottom that electrically heated rod is placed in heat storage can, to heat whole jar of heating and life hot water like this, time heating with regard to the continuous several hrs of large power, electrically heating rod of handy tens kilowatts or tens kilowatts, power consumption height not only, and also must carry out the dilatation of power supply at the installation initial stage, and both improved the cost of cloudy heating, also increased the mounting cost of solar heating.

In addition, the connecting pipe on most heat storage cans all is in the outside unsettled jar bottom of setting up of jar, converges to together again, and is so both unbecoming, also increases the pipe insulation cost, and it is stifled to keep away freezing of unavoidable dissipation of heat energy and pipeline.

Also have, heat collector easily breaks and fracture defect easily takes place circulating line, manages fault and can not in time find in case break or break, and the hot water in the heat storage can will be given out light, and causes waste.

The recirculated water of solar heating system is the water of handling through softening besides, circulates repeatedly in system in addition and heats, and can not use as domestic water.Iff being used for the indoor heating in winter, just make the overwhelming majority's that solar heating system provides throughout the year heat energy waste.

Summary of the invention

In order to overcome the above listed defective of solar heating system heat storage can, the utility model provides a kind of multifunction energy-saving heat storage can.But this heat storage can is not only in cloudy day heating using electricity wisely, and the inside and outside high temperature difference area of dissipation of jar and the area of dissipation of jar body connecting pipe when having reduced electrical heating, and in heat-insulation layer, set up heat insulation layer to strengthen heat-insulating property, can also prevent to break or circulating line fracture causes heat storage can hot water to run off and drinkable boiling water and other domestic water are provided throughout the year, thereby save a large amount of energy because of solar thermal collector.

The utility model solves the technical scheme that above power saving adopts:

The one, electrically heated rod is arranged on heat storage can top can satisfies once the circulate its lowest position of required water amount of heating system, like this with regard to a spot of water in electrically heated rod heating tank within a short period of time of available smaller power.The jar internal-external temperature difference is big more, and dispersed heat is also just many more in the unit are time.Reduce electrically heated volume, just reduced the high temperature difference area of dissipation, also just reduced heat-energy losses, also reduced the hot water that the complete jar water of electrical heating causes simultaneously and crossed the waste of energy that Sheng produces.

The 2nd, a heat insulation layer is laid at the tank skin place in pressing close in heat-insulation layer, to strengthen the hot-resistant heat-preserving performance.

The 3rd, the pipeline that the jar outer scattered is in disorder is placed in close heat insulation layer place in the tank body insulation interlayer, converges to insulation together at pot bottom, has just reduced the insulation material of this part pipeline, and has avoided the heat energy dissipation of this part pipeline and frozen stifled.

The 4th, on pot bottom heating circulation water inlet pipe, thermal-arrest recycling outlet (real is same pipe) mouth, be provided with a up and down dash device.When water level in the jar during in setting height, the dash device is lifted to setting height by the ball-cock assembly ball float through hauling rope.When heating system moved, the radiator backwater looped back water pipe from heating and flows in the jar.Because being subjected to the dash device stops, the backwater of lower temperature can not impact vertically upward, in the blending tank hot water and slowly level loose to all the winds, in promoting jar from low to high the water of different temperatures level from bottom to top steadily gradually preface rise, thereby be that top is that water, the bottom of higher temperature is the water of lower temperature all the time in just having guaranteed jar.At the collecting system circulation time, the water at low temperature of jar bottom just in time flows out jar earlier, flow to solar thermal collector, and the hot water storage that loops back is on jar top.The water that remains higher temperature in the jar bottom, had both guaranteed the concentrated use of high-temperature water at the water of jar top, lower temperature, had reduced the area of dissipation of jar inside and outside high temperature difference again, had just saved heat energy.

Solar thermal collector breaks or the circulating line fracture if take place, the recirculated water outflow, heat storage can ball-cock assembly ball float is followed water level to descend and just the dash device is come downwards to the thermal-arrest recycling outlet mouth of pipe, by the water outflow, closed electromagnetic valve on the while demineralized water conveyance conduit, stop moisturizing, thereby reduce the waste that hot water runs off.

The 5th, the demineralized water carrier pipe is extended to pot bottom from jar top ball-cock assembly, the demineralized water that makes lower temperature is hot water in unlikely impact when the demineralized water filling pipe that is provided with the dash device flows out, blending tank at the bottom of the jar, to guarantee jar concentrated use of top high-temperature water.

The 6th, in heat storage can, be provided with heat exchanger, running water absorbs by heat exchanger promptly becomes drinkable boiling water after the high temperature heat and hot water use in other life, and the heat energy that so just can make full use of the long-term collection of solar heating system provides a large amount of life hot water.

The beneficial effects of the utility model are, broken through a difficult problem that in jumbo heat storage can, heats than the water of low capacity, thereby reduced the power of electrically heated rod, shortened the electrical heating time, the area of dissipation of jar inside and outside high temperature difference and the area of dissipation of jar body pipeline have been reduced, avoided the complete jar water of electrical heating to cause hot water to cross the waste of energy that Sheng produces, and can prevent to run off because of the heat storage can hot water that solar thermal collector breaks or the circulating line fracture causes, the cold water and the backwater that prevent lower temperature impact, hot water in the blending tank and guarantee the concentrated use of high-temperature water, can also provide drinkable boiling water and other life to use hot water throughout the year, thereby save a large amount of electric energy and heat energy.Overcome solar heating in addition and popularized to family and run into the little problem of household electrical source power, made solar heating popularize and to realize to family.
