Operation principle
With the solar water heater of solar energy as thermal source, utilize solar energy to make the superconductive medium vaporization produce gas, the heat-exchange device in pipeline delivers into the pressure-bearing casing, and by the realization of the water in heat-exchange device and pressure-bearing casing heat exchange.Bog after heat exchange is finished under the effect of circulating pump, reenters solar energy heat build-up system with the form of condensate liquid, thereby realizes working cycles.When sunny, only utilize solar energy just can make the water in the high-pressure tank body reach temperature required, hot water is discharged by pressure-bearing casing delivery port, directly uses for the user, satisfies the productive life needs; In sunlight deficiency or water tank, have under the situation of after-heat, tentatively heat or have the interior water of pressure-bearing casing of after-heat through solar energy, under atmospheric pressure state, enter in many curved protrusion of quick electric water heater device between the pipe and many curved protrusion outer tube in the formation fluid cavity.Superconductive medium in the superconductive medium storage cylinder is through electric heater for heating, vaporization rapidly, rise along many curved protrusion inner tube wall, and be delivered to many curved protrusion outer wall of inner tube in heat conducting mode, with in many curved protrusion and the water in many curved protrusion outer tube fluid cavity realize the Rapid Thermal exchange, cooled condensate liquid falls back to the bottom, reheats, vaporizes, realizes circulation, and the hot water that heated through quick electric heater unit provides the user to use by hot water outlet.
The thermal source that enters heat-exchange device in the pressure-bearing casing can be varied, such as all utilizable energy such as solar superconducting liquid, steam, thermal technology's industry tail gas, spent hot water, underground heat, thereby finally realizes many thermals source Fast Heating.
The present invention has tangible technology and economic advantages
1, heat exchange area is big, is about 1.8 times of same specification pipe.Heat exchange structure in heat-exchange device and the quick electric heater unit all adopts the metal tube of the many curved protrusion that form inside and outside increase-volume or the metallic plate of many curved protrusion, makes the heat energy of high-temperature region be delivered to low-temperature space rapidly, realizes the Rapid Thermal exchange.
2, electricity separation, security performance height, be difficult for scaling, long service life: usually electric heating tube is arranged in the water and works, and the environment temperature height easily forms incrustation scale, hinders the carrying out of heat exchange.In the pressure bearing stored water tank of the present invention heat-exchange device only is set, no electric heating tube.Electric heating tube in the electric heater unit adopts two sleeve pipe forms fast, and water does not directly contact with electric heating tube, is difficult for scaling, long service life.
3, the heat transfer rate is fast, efficient is high, owing to be negative pressure state in the pipe after pipe vacuumizes in many curved surfaces, makes the superconductive medium boiling point that itself just has the cold-starting characteristic reduce, and reaches impayable heat exchange effect.When starting electric heater unit, heat energy constantly distributes, and can reach temperature required rapidly and make each curved surface of pipe and required heated liquid realization heat exchange in many curved surfaces.
4, thermal source wide material sources: the selection of thermal source is various informative, waste heat tail gas, underground heat and solar energy after electric energy, the burning.With solar energy is example: bog or steam that solar water heater produces are main thermals source, and solar energy has unrivaled advantage as the energy of general energy-conserving and environment-protective.
3, using water wisely, make full use of the energy: the phenomenon that reality of the present invention has solved the displacement type water heater waste and waited for, and the higher problem of quick electric water heater power, reasonably solar water heater and quick electric heater unit are used in combination, making does not need preheating, instant-heating need not to wait for that the heat in the time of can not producing insulation simultaneously scatters and disappears.Water in the pressure-bearing casing tentatively heats owing to passing through bog, and reaches certain temperature, is heating energy savings via the quick electric water heater device.Calculate by common three-person household, if on average everyone bathing water is 20 minutes, the bathing water temperature is 45 ℃, and flow calculates according to the maximum amount of water 4L/min that soap lather can be rinsed, i.e. water consumption 80L/ people.Suppose that the capacity of general displacement type water heater is 100L, power is 2500W, and the running water initial temperature is 15 ℃.If these water are heated to 75 ℃, do not having to need 160 minutes under the situation of energy loss.In order to reach the temperature of having a bath, need in 75 ℃ hot water, inject the 100L running water, make that total hot water amount is 200L, but still can not satisfy the hot water use amount of three-person household.Need to continue inject running water and heating, remaining in theory 20 liters 75 ℃ water mixes the back temperature with the part (20L) of the new running water that injects can reach 45 ℃, thus need heat remaining 60L running water to 45 ℃, approximately need 50 minutes.After but heating is finished only people use, consume 80L, wasted remaining 20L water, just wasted and make this 20L water from 15 ℃ to 45 ℃ energy, be equivalent to 2.5 degree electric energy.Certainly, in fact under the adjusting of automatic water feeding instrument, use how much water, just inject corresponding water at any time, waste more serious.When using combined multi-heat source rapid water heater, even if in the winter of cold, the solar energy Accumulated Heat Units also can reach 25-35 ℃, water in the preliminary heating pressure-bearing casing, make it be elevated to certain temperature, being heated to 45 ℃ through quick electric heater unit can use, and can what use, heating how much, energy savings.
6, rational in infrastructure, cost of investment is moderate, applied range, easily universal.
