The objective of the invention is problem, a kind of design of high-temperature heat accumulation electric boiler of passive conversion is provided at above-mentioned existence.Utilize the principle of the unidirectional conduction heat of heat pipe, by changing the angle of itself and ground perpendicular, control high-temperature heat accumulation electric boiler discharges the high temperature heat of being held constantly by user's request.Therefore, cancelled in the existing system, the corollary equipment and the dynamic power of high temperature required high temperature high voltage resistant when middle temperature is changed are realized the energy conversion system that passive delivery cooperates.
Main jar among the present invention is the pressure-bearing energy storage tank of high-temperature heat accumulation electric boiler.The construction size and the manufacture process requirement of design work temperature and amount of stored heat decision tank body.Electric heater, heat exchange of heat pipe, sensor and tumbler are installed on the main tank body.During work, the water and the salt that are full of in the main jar after deoxygenation and softening the processing are done primary fluid.Selected inorganic salts is tackled interior all the metal device surfaces that contact with primary fluid of main tank body passivation or corrosion inhibition.Because main tank body outer surface is provided with heat insulation layer, the high temperature heat that Gu Qisuo holds is mainly by high efficient heat exchanging element-heat pipe, and the secondary heating agent in secondary jar carries out the energy transmission.Because primary fluid is poured in the airtight main tank body, do not contact with the external world, guarantee main jar tank body longevity, safety, reliability service.
Secondary jar among the present invention is non-pressure vessel.Be provided with domestic water heat exchanger, direct power supply heater, heat outputting interface and secondary heating agent in secondary jar.Also be provided with monitoring and control sensor simultaneously.The heat energy that the secondary heating agent will obtain from main jar to the defeated heat of hot device, also can promote temperature for domestic water by the circulatory system.The purpose that the direct power supply heater is set is during main jar of accumulation of energy or accumulation of heat when not enough, uses when the secondary heating agent being heated temporarily.The selection of secondary heating agent is pressed the operating mode of external circulating system and is determined.
Because main jar and secondary jar are coupled to one, heat exchange of heat pipe axis and major and minor jar of circle center line connecting place are at grade.As long as by the rotation of main tank, change heat pipe axis and ground perpendicular angle, can control the output of institute's accumulation of heat energy, can make the arbitrary use valley electricity of user.Aspect regulation and control, can realize unattended automation mechanized operation program.
Below in conjunction with accompanying drawing the present invention is further elaborated:
Fig. 1 is a main pseudosection of the present invention.
Fig. 2 is a side view of the present invention.
Fig. 3 is four kinds of operating mode position views of the present invention.
Accompanying drawing 1 is a main pseudosection of the present invention.Illustrate as seen, the present invention forms with secondary jar two parts by main jar.Main jar comprises: main tank 1, electric heater 3, heat exchange of heat pipe 4, tank body rotary system 5, safety valve 6 etc.Secondary jar comprises: secondary tank 2, direct power supply heater 7, domestic water heat exchanger 8 etc.The major-minor tank is equipped with heat insulation layer 9 and temperature sensor etc. outward.Main jar and secondary jar is adopted the bolt mode to be coupled to one.Rotation drives by stepper motor.
Accompanying drawing 2 is side views of the present invention.Illustrate as seen, master's jar periphery of the present invention is provided with supporting guide 10, rotation tooth bar 11.A secondary jar periphery is provided with domestic water interface 12 and 13 heat supply interfaces are a pair of.
Accompanying drawing 3 is four kinds of operating mode position views of the present invention.When No. 1 the position is low ebb electricity accumulation of energy work, secondary jar present position.Because heat exchange of heat pipe axis and ground perpendicular angle are less than 90 °, heat pipe stops heat conduction, and main jar of interior primary fluid accumulated into high temperature heat by electric heater.This moment is domestic hot-water or interim with heat if desired, can be by the direct power supply heater heat-obtaining in secondary jar.Less because of secondary jar volume, it is rapider to heat up, and uses when being prepared for urgent need.When accumulation of energy reached design temperature, equipment was cut off the electricity supply automatically.No. 2 the position utilizes the high temperature heating agent secondary jar of residing operating mode position when indoor heating that stores in main jar for the flat, peak power period.When the axis of heat exchange of heat pipe and ground perpendicular angle were equal to or greater than 90 °, heat exchange of heat pipe was started working.With the high temperature heat in the primary fluid, the secondary heating agent in heat exchange of heat pipe conducts to secondary jar, secondary heating agent then by the heat supply circulatory system to hot device heat supply.The output of heat is the automatic control of hommization very.If when institute's amount of stored heat is not enough, also can replenish required heat by the direct power supply heater.Secondary jar of residing operating mode position when No. 3 position is secondary jar of maintenance or transposing heat exchange of heat pipe.The axis normal of heat exchange of heat pipe is in ground level at this moment, and the heat exchange of heat pipe mount pad on the tank body can be avoided the excessive of primary fluid at main jar top when disassembling.No. 4 positions are that new equipment is installed or main jar electric heater overhauls when changing, secondary jar of residing operating mode position.Because of primary fluid is to inject main tank body by electric heater installing hole place.This moment, electric heater mount pad hole was in main tank body top, met the process conditions that liquid fills.When equipment is installed or is mobile, for alleviating the weight of high temperature accumulation of energy electric boiler, be convenient to operation, primary fluid can be transferred in other container, pour into back again behind the location in main jar.When repairing when changing electric heater, can avoid primary fluid to run off or fill and add deficiency too in this position operation.Because primary fluid is a high-temperature heat accumulation, can make the more common heat storage boiler volume of equipment volume little by about 40%.Major and minor jar is adopted the bolt mode, is convenient to the cleaning of secondary heating agent recirculating network.Be equipped with the control system of hommization, will become single building heating or small enterprise first-selection with heat.
