Abstract
The present invention relates to an electric heating device, in particular, it relates to an electromagnetic induction heat-storing device closely related to human life, and is mainly technically characterized by that said device adopts magnetic-conductive heat-storing body, its power supply is alternating current, and uses valley electricity as energy source, and is equipped with cooling water electromagnetic pipe, so that the temperature of the heat-storing body can be raised to limit temperature, and the floor area of the equipment can be greatly reduced, and the equipment investment can be reduced.
Description
Technical Field
The invention relates to a valley power heat storage device, in particular to an electromagnetic induction heat storage device which can provide high-temperature air in the fields of steam production of gas boilers, central air conditioning of hotels, household heating, gas water heaters, cookers and the like, and can realize energy conservation and emission reduction.
Background
The invention mainly aims at improving the efficiency of the existing industrial steam boiler, hotel central air conditioner and other equipment needing air.
Taking an industrial boiler as an example, at present, the industrial boiler mainly uses natural gas as fuel, heats water into high-temperature and high-pressure saturated steam, supplies the saturated steam to various heat consumers, and needs to supplement a large amount of ambient air in the combustion process of natural gas, wherein the temperature of the ambient air is normal temperature, namely about 20 ℃, the nitrogen in the air accounts for about 80%, the oxygen accounts for about 20%, and the nitrogen does not play any role in the process of releasing energy from the fuel, but rather plays a reaction role.
This process exists for any area where fuel is consumed.
Because natural gas is a high-quality fuel and is high in price, the cost pressure of users is huge, and the natural gas is generated for reducing the production cost of the users.
Disclosure of Invention
The present invention is directed to a more advanced electromagnetic induction heat storage device in view of the above-mentioned technical situation.
In order to balance the load, the power grid encourages people to adopt peak-valley electricity, namely, a power supply is used when the load of the power grid is extremely low late at night, and preferential electricity price is given. The price is far lower than the primary energy price of natural gas, and the method has great attraction. Therefore, when the user is at the valley bottom, the electric energy of the power grid is used.
Drawings
Fig. 1 is a front sectional view, fig. 2 is an external plan view, and fig. 3 is a left sectional view of an embodiment of the electromagnetic induction thermal storage apparatus.
Detailed Description
Referring to fig. 1, the electromagnetic induction heat storage device of the present invention includes a magnetic conduction heat storage body 1, and an electromagnetic coil 2 wound around the magnetic conduction heat storage body 1;
furthermore, the end of the electromagnetic coil 2 is connected with a power supply terminal 3, and the power supply terminal 3 is connected with a remote alternating current power supply.
Furthermore, the electromagnetic coil 2 is hollow, cooling water is filled in the electromagnetic coil, and a cooling water inlet 4 and a cooling water outlet 5 are respectively connected to an inlet and an outlet of the electromagnetic coil 2.
Further, the magnetic conduction heat accumulator 1 has magnetic conductivity, and when a surrounding alternating current passes through the outside of the magnetic conduction heat accumulator 1, an induced current (eddy current) is generated in the magnetic conduction heat accumulator, and the eddy current generates joule heat in the magnetic conduction heat accumulator 1.
The working principle is as follows:
when the power supply terminal 3 is connected with an alternating current power supply, the electromagnetic coil 2 forms a rotating electromagnetic field, the rotating electromagnetic field generates induction current on the magnetic conduction heat accumulator 1, the current generates joule heat, namely electric heat, on the magnetic conduction heat accumulator 1, so that the temperature of the magnetic conduction heat accumulator 1 gradually rises until reaching the set temperature, and then the power supply is stopped.
Since the final temperature of the magnetic conduction heat accumulator 1 may exceed the tolerance temperature of the electromagnetic coil 2, a cooling water loop is provided, and high-temperature cooling water can be delivered to boiler water supplement or other heat utilization equipment.
The benefits of this are:
adopt the electromagnetic induction heating heat accumulator, can follow the inside direct heating up of magnetic conduction heat accumulator 1, like the microwave heating principle, avoided arranging electric heating pipe from the outside and carried out the inefficiency of direct radiation heating, the electric heating pipe mode can only be followed the outward appearance of heat accumulator and slowly inwards conducted and be heated, therefore rate of heating is slow, and is inefficient, and heat time is long, leads to outside heat dissipation loss big, the thermal efficiency is low.
The upper limit of the temperature of the magnetic conduction heat accumulator 1 is generally 750 ℃ in the mode of adopting the electric heating pipe, which cannot be improved, namely the upper limit of the temperature resistance of the material of the electric heating pipe is limited, so that the energy efficiency of the heat accumulation material is reduced.
And adopt electromagnetic induction heating magnetic conduction heat accumulator 1, then can rise the temperature of heat accumulator to more than 1000 degrees, just so greatly reduced equipment cost, improved technical adaptability.
Furthermore, the electromagnetic induction power supply can adopt power frequency, intermediate frequency or even high frequency.
Furthermore, the magnetic conduction heat accumulator 1 can be made of all magnetic conduction materials directly or can be embedded with part of magnetic conduction materials to be used as an induction thermonuclear.
Furthermore, the magnetic conduction heat accumulator 1 is arranged in various combinations according to the heat load required on site.
The electromagnetic induction heat storage device designed according to various field requirements can convey heat outwards after the heat storage process is finished, the heat conveying mode generally can adopt hot air (air or other inert gases), heat conduction oil, liquid water or modes of heat exchange again and the like, heat storage can be carried out again after the heat conveying is finished, and the process is repeated in a circulating mode.
The present embodiment only shows one embodiment of the electromagnetic induction heat storage device, and any similar technical modifications based on the spirit of the present invention fall into the protection scope of the present invention.
