Abstract
The invention discloses an excitation-type eddy-current heating technique, which has a technical key point that an eddy-current heater consists of a stator (1) and an excitation rotor (2) through a rotor shaft (3) and a bearing (4), and the excitation rotor (2) rotates in the stator (1) under the drive of mechanical force so as to enable the inside of the stator (1) to obtain a changing magnetic field and cause eddy-current heating. The technique is a brand-new wind energy utilization technique which overcomes the disadvantages of numerous steps, high cost, low efficiency and the like when the prior wind-energy heating devices heat through a process of transforming wind energy into electricity and then heat, a process of transforming wind energy, compressing air and throttling air, a process of transforming wind energy into heat energy through mechanical stirring or other processes.
Description
Technical field
The present invention relates to a kind of excitation-type eddy-current heating technique.
Background field
Wind energy is the regenerative resource of inexhaustible, nexhaustible cleaning.The whole world available wind energy resources be 20,000,000,000 KW, for can utilize water can 20 times.China only land can utilize wind energy just to reach 2.53 hundred million KW.Along with developing rapidly of China's economic construction, to the demand sharp increase of the energy.Meanwhile, be that the fossil energy of representative is but reducing year by year with oil, coal, natural gas etc., energy problem may become the bottleneck of China and even development of world economy.For this reason, countries in the world have all been formulated the development and use planning of regenerative resource.Wind Power Utilization not only is in crucial status in renewable energy utilization, and presents very bright prospect.
Wind energy can be converted into electric energy, mechanical energy, is industrial and agricultural production and national defense construction service.With wind energy transformation is that heat energy is used, and also will play a significant role in industrial production, life, farming and animal husbandry production, field and frontier defense energy supply, and meaning is more great.Industrial, can be used for petroleum refining, chemical industry, thick oil filling vapour is used for the sentry post heating in the frontier defense.In China vast agricultural and animal husbandry area, be used for featured agricultures such as hot house and aquaculture, and the life heating etc.
So far, with three kinds of methods wind energy is converted into heat energy usually, that is: 1) utilize wind power generation, generate heat by electric heater again; 2) be the air pressure energy by wind energy conversion system with wind energy transformation, through exhaust heat energy band place be used again; 3) wind energy is converted into heat energy.Though the efficient that first kind of mode electric energy is converted into heat energy is higher, because that wind energy transformation is the efficient of electric energy is not high, this method is uneconomic; The second way, air are by adiabatic compression, and temperature, pressure raise, and when obtaining heat energy, have also obtained the pressure energy, but need the multi-form energy load device of two covers; In the third mode, be divided into solid friction pyrogenicity, agitated liquid pyrogenicity again and utilize conductor cutting magnetic line generation electric current to form vortex flow again and modes such as pyrogenicity.Stir that pyrogenicity and conductor cutting magnetic line produce that electric current forms vortex flow again and the efficient of modes such as pyrogenicity neither be very high.
Summary of the invention
The purpose of this patent provides the heat utilization technology of a kind of more dynamical wind-heat reforming unit for wind energy, relate to the design of pipe fitting excitation-type eddy current heater, direct dynamic action by wind energy, make the magnetic field of permanent magnet present periodical high-frequency rate " break-make " phenomenon, in the METAL HEATING PROCESS body, produce electromagnetic induction eddy current, reach the purpose of high-effect heating.
Implementation procedure of the present invention is as follows:
A kind of excitation-type eddy-current heating technique, it is characterized in that: eddy current heater is made of by armature spindle (3) and bearing (4) stator (1) and excitation rotor (2), excitation rotor (2) rotates in stator (4) under mechanical force drives, and makes to obtain the magnetic field that changes in the stator (4) and cause eddy-current heating.
Eddy current heater stator (1) belongs to soft magnetic material, and its height, internal diameter and outside dimension are adjustable; Eddy current heater excitation rotor (2) belongs to the soft magnetic material that is wound with magnet exciting coil, and its height and outside dimension are adjustable.
The present invention is a kind of brand-new Wind Power Utilization technology, and it has overcome in the past in the wind energy heater, pass through wind → electricity → heat, wind → compression → throttling, shortcoming such as existing step was many when processes such as wind → mechanical agitation heated, cost is high, efficient is low.
