Description
Technical field
The invention belongs to Electromagnetic Heating field, heats more particularly, to internal heating type electromagnetic induction air flow in a kind of glass piping
Device.
Background technology
Gas to flowing through in pipeline is heated, and is one of important means of engineering or experiment.Heating means have a lot,
Size, temperature range, medium species generally according to unit scale is being selected.It is on Pilot Unit and instrument, many
Using outside heating wire or electric heating band winding, then the mode for adding heat insulation layer is applied, also by pipeline by way of electrothermostat.
When the shortcoming of above two mode is homoiothermic, hysteresis are serious, during in particular according to requiring using glass piping, because glass
Heat conductivility is poor, so hysteresis become apparent from.Additionally, also there is the shortcomings of scattered consumption rate of heat is high, volume is big.
Chinese patent CN101998710A discloses a kind of electromagnetic induction heater, including metal expects pipe and inductor,
Inductor is constituted by induction coil is axially aligned, and the periphery of metal expects pipe is provided with nonmetallic materials thermal insulation layer, inductor ring
The cylindrical of nonmetallic materials thermal insulation layer is wound on, the often circle induction coil of inductor disconnects shape for concordance vertically, by connection card
The often circle induction coil correspondence that button will be switched off is docked, and forms the induction coil of closure；The periphery of inductor is provided with the modeling of two halves formula
Plastic boot, including left plastic jacket and right plastic jacket, are provided with cooling water cavity in left plastic jacket and right plastic jacket, left
The inwall of plastic jacket and right plastic jacket is provided with conductive non-magnet_conductible material layer.The patent is primarily with respect to electromagnetic induction coil
Construction is improved, and is connected using semi-circular shape step by step, it is easy to install, and magnetic field produces vortex flow on metal tube and makes metal tube
Heat up, heating wherein material.The industrial dress that its induction coil is that the number of turns is few, electric current is big be can be seen that by cooling water cavity is arranged
Put, the electromagnetic induction coil in the present invention, similar to electromagnetic oven, is that the number of turns is more, the form that electric current is little, the heat that coil itself is produced
Amount very little.
The content of the invention
The purpose of the present invention is exactly to provide one kind to overcome the defect of above-mentioned prior art presence, is changed into from external-heat
Internal heat type, during using high-frequency alternating current or high frequency pulse dc electricity by coil, the alternating magnetic field that produces or pulsed magnetic field, make glass
Tinsel loop in glass pipe produces induced current, to heat internal heating type electromagnetic sensing gas in the glass piping of the gas in pipeline
Stream heating apparatuss.
The purpose of the present invention can be achieved through the following technical solutions：
Internal heating type electromagnetic induction air flow heating apparatuss in a kind of glass piping, including：
Quartz glass tube,
The triangle spiral metal wire loop being arranged in quartz glass tube,
The solenoid being arranged on outside quartz glass tube,
For the power supply of solenoid.
The both helical ends in described triangle spiral metal wire loop turn back tailing edge centrage connect composition loop, spiral return
The number of plies on road is required according to heating-up temperature and electromagnetic field intensity is calculated and determined.
The summit in described triangle spiral metal wire loop is abutted against with the inwall of quartz glass tube.
The cross section in described triangle spiral metal wire loop is equilateral triangle structure, such helical loop and glass tubing
For a contact, it is possible to reduce tube wall conducts heat, and improves the efficiency of heating surface.
It is made up of platinum filament or nickel wire in described triangle spiral metal wire loop.
Described power supply is adjustable high-frequency alternating current power supply or pulse dc power.
Described solenoid high-frequency alternating current or pulse direct current by when produce alternating magnetic field or pulsed magnetic field, make
Tinsel loop in quartz glass tube produces induced current, so as to be heated.
Compared with prior art, the present invention is changed into internal heat type from external-heat, using high-frequency alternating current or high frequency pulse dc
The alternating magnetic field produced when electricity is by coil or pulsed magnetic field, make the tinsel loop in glass tubing produce induced current, to add
Gas in pipe line, with advantages below：
1) homoiothermic is rapid, and after changing supply frequency, air-flow can change rapidly temperature, delayed very little；
2) efficiency of heating surface is high, and triangle spiral metal wire loop is contacted by point with glass tube walls, the heat for outwards dissipating
Seldom；
3) small volume, it is adaptable to narrow space；
4) simple structure, fault rate are low；
5) long service life.
