Abstract
The present invention relates to a kind of high-temperature gas electric heating tube, belong to electroheat technology field in electricity.This high-temperature gas electric heating tube includes steel pipe, the termination stretching out outside steel pipe and the contact rod being located in steel pipe, resistance wire and insulating porcelain piece, contact rod one end is welded with resistance wire and its other end welds with termination, resistance wire passes insulating porcelain piece, on steel pipe sidewall, interval is shaped with the opening of multiple through steel pipe outboard sidewalls, and resistance wire is directly contacted with steel pipe extraneous gas by opening.This high-temperature gas electric heating tube has the advantage that firing rate is fast, heat transfer good and operating temperature is high.
Description
Technical field
The present invention relates to a kind of high-temperature gas electric heating tube, particularly relate to that a kind of firing rate is fast, heat transfer is good and work temperature
Spend high electric heating tube.
Background technology
Existing electric heating tube, it includes steel pipe, is provided with heater strip, heater strip periphery filling heat conductive insulating material in steel pipe
Material.Wherein, heat-conducting insulation material is made up of magnesia powder, filler particles thing.
According to the applicant understood, not being resistant to 800 DEG C of high temperature above owing to filling out fair magnesia powder, at high temperature, existing electricity adds
The hot insulation of heat pipe is low, leakage current is big, and under high temperature, magnesia powder goes bad failure of insulation, and final electric heating tube is electrically shocked to be worn easily
Cause the accident of leakage under high temperature.
The defect such as firing rate is slow, heat transfer efficiency is low it addition, existing electric heating tube exists, electrothermal tube service life is short.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, propose that a kind of firing rate is fast, heat transfer is good and
The high-temperature gas electric heating tube that operating temperature is high.
The present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of high-temperature gas electric heating tube, including steel
Pipe, the termination stretched out outside described steel pipe and the contact rod being located in steel pipe, resistance wire and insulating porcelain piece, described contact rod
One end is welded with resistance wire and its other end welds with termination, and described resistance wire passes insulating porcelain piece, described steel pipe sidewall
Upper interval is shaped with the opening of multiple through steel pipe outboard sidewalls, and described resistance wire is direct and steel pipe extraneous gas by described opening
Contact.
The present invention uses technique scheme, thus brings following effect: the present invention be spaced on steel pipe sidewall be shaped with many
The opening of individual through steel pipe outboard sidewalls, resistance wire is directly contacted with steel pipe extraneous gas, in electric heating tube by this opening
Heating wire directly contact heating with gas, firing rate soon, conduct heat, operating temperature height, solve and existing fill out fair magnesia powder
Electric heating tube non-refractory, the most hot insulation is low, leakage current big, under high temperature, magnesia powder goes bad failure of insulation,
Final electric heating tube is made to be electrically shocked the defect worn.
The improvement of technique scheme is: described opening is the length 50～60mm, wide 10～20mm being shaped with at steel pipe sidewall
Strip opening, described opening along steel pipe axially spaced-apart 50～60mm arrange and uniform along steel pipe circumferentially-spaced 20～30mm.
The present invention uses technique scheme, thus brings following effect: by being shaped with strip opening at steel pipe sidewall,
Opening is arranged and uniform along steel pipe circumferentially-spaced 20～30mm along steel pipe axially spaced-apart 50～60mm, it is ensured that resistance wire is to gas
Heat is uniformly exhaled after heating.
The improvement of technique scheme is: described resistance wire is that two ends are each passed through the U of wire hole in each insulating porcelain piece
Shape resistance wire.
The improvement of technique scheme is: be uniformly fixed with multiple support member on described steel pipe lateral wall.
The present invention uses technique scheme, thus brings following effect: by being uniformly fixed with on steel pipe lateral wall
Multiple support members, both ensure that steel pipe intensity at high temperature, had made again steel pipe Homogeneouslly-radiating.
Accompanying drawing explanation
The invention will be further described below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the high-temperature gas electric heating tube of the present invention.
Fig. 2 is the schematic cross-section of Fig. 1 steel pipe.
Detailed description of the invention

End welds with resistance wire 3 and its other end welds with termination 1, and resistance wire 3 is through insulating porcelain piece 4.The resistance of the present embodiment
Silk 3 is that two ends are each passed through the U-shaped resistance wire of wire hole in each insulating porcelain piece 4.
As in figure 2 it is shown, interval is shaped with the opening 51 of multiple through steel pipe 5 outboard sidewalls on steel pipe 5 sidewall, resistance wire 3 leads to
Cross opening 51 directly to contact with steel pipe 5 extraneous gas.
The opening 51 of the present embodiment is the length 50～60mm, wide 10～the strip opening of 20mm being shaped with at steel pipe 5 sidewall,
Opening 51 is arranged and uniform along steel pipe circumferentially-spaced 20～30mm along steel pipe 5 axially spaced-apart 50～60mm.The steel pipe 5 of the present embodiment
Multiple support member 6 uniformly it is fixed with on lateral wall.
The present invention is not limited to above-described embodiment.The technical scheme that all employing equivalents are formed, all falls within the present invention
The protection domain required.
