Description
Technical field
This utility model relates to duct type electrothermal device, specifically, relates to cryogenic high pressure duct type electrothermal device in one.
Background technology
Working medium heater can be divided into external heat and interior heating two ways at present.Interior firing equipment mainly has recirculation heater, additional
Hot mode mainly has heating furnace, Electromagnetic Heating, heat-conducting oil heating etc..Circulating heater uses metal shell to surround heater element
And heated fluid, power is relatively big, the highest can pressure 20Mpa, high-temperature resistant 600 DEG C.Outside heat-conducting oil heating mostly is by pipe
Heat convection heat, heating furnace by heat radiation to fluids within pipes heat.
When using recirculation heater, will reach higher operating pressure, heater housings, sealing member, connection member need bigger
Size, equipment often becomes the heaviest, investment to be increased, and recirculation heater generally uses silica gel and ceramic seal, and
Common silica gel will lose efficacy when more than 300 degrees Celsius, and the encapsulant more resistant to temperature faces the sharp increase in price, and fluid warp
When crossing recirculation heater, becoming suddenly big due to passage, air deflector flows to transfer, therefore when fluid velocity is bigger, and pressure
Power loss is bigger, recirculation heater is safeguarded more complicated, more difficult maintenance after the heat-generating pipe damage inside heater.And it is additional
Hot equipment is often because thermal diffusion causes the efficiency of heating surface the highest, and because the overall coefficient of heat transfer is low, faces high temperature protection, insulation etc.
Problem, easily goes out security incident.Such as, heat-conducting oil heating, generally require the biggest heat-conducting oil heating recycle unit.Heating furnace spoke
Penetrating heat exchange then efficiency lower, thermal diffusion is serious.Electromagnetic heater is not then suitable for accurate temperature and controls occasion, and accurate temperature controlling needs
Other auxiliary equipments, and radiation face more greatly non-controllable risk.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, it is provided that cryogenic high pressure duct type electrothermal device in one,
The advantages such as this heater has compact conformation, and efficiency is high, safe and reliable.
The purpose of this utility model is achieved through the following technical solutions:
Cryogenic high pressure duct type electrothermal device in one, including the outer tube being made up of seamless steel pipe, outer tube be internally provided with heating
Pipe, what the two ends of described outer tube were symmetrical is fixedly connected with three way cock, is provided with sealed base in described three way cock, described
Be provided with the circular hole for fixing described heat-generating pipe in the middle part of sealed base, described sealed base be orderly arranged outside each polytetrafluoroethylsealed sealed ring
With the clamp nut of hollow, described polytetrafluoroethylsealed sealed ring is provided with at least two, and described heat-generating pipe is by electrode, heating wire and heat conduction material
Material is constituted.
Described polytetrafluoroethylsealed sealed ring was tight fit with outer wall and the three way cock of described heat-generating pipe.
The external diametrical extent of described outer tube is 18-25mm.
Compared with prior art, the technical solution of the utility model is had the benefit that
1. compared with circulating heater compare, the bearing capacity of this utility model heater depends primarily on the thickness of seamless steel pipe
Degree and the sealing property of polytetrafluoroethylsealed sealed ring, therefore can bear higher pressure on the premise of lower cost.
2. being directly arranged at by heat-generating pipe in heater outer tube fluid, fluid directly washes away heat-generating pipe, therefore relative to tradition
Heater, the thermal resistance between heat-generating pipe and fluid is greatly reduced, thus improves the efficiency of heat exchange, and then reduces heat exchange area.
3. this utility model heater is safeguarded very simple, after heat-generating pipe or sealing ring damage, by unscrewing clamp nut,
Heat-generating pipe is extracted out, it is easy to carry out the replacing of polytetrafluoroethylsealed sealed ring or heat-generating pipe.
4. heater outer tube uses the external diameter seamless steel pipe less than 25mm, and entirety is compacter, it is easier to be arranged in multiple
In miscellaneous tubing, additionally due to the inside of heater outer tube is straight channel, the pressure loss of fluid is the least, therefore relative to
Circulating heater, is more applicable for high-velocity fluid.

Detailed description of the invention
The utility model will be further described below in conjunction with the accompanying drawings:
As it is shown in figure 1, cryogenic high pressure duct type electrothermal device in one, including the outer tube 1 being made up of seamless steel pipe, outer tube 1
External diameter less than 25mm, outer tube 1 be internally provided with heat-generating pipe 3, what the two ends of outer tube 1 were symmetrical is welded with three way cock
2, constitute the annular-heating passage of heater, wherein three way cock 2 Main Function is to send out heat-generating pipe 3 for inside to provide support, close
Envelope internal high pressure fluid, and connect exterior line by nipple 8.It is provided with sealed base 4 in three way cock 2, seals
Base 4 is structure as a whole with three way cock 2, and the middle part of sealed base 4 is provided with the circular hole for fixing heat-generating pipe 3, seals the end
The clamp nut 6 being orderly arranged outside each polytetrafluoroethylsealed sealed ring 5 and hollow of seat 4, in the present embodiment, polytetrafluoroethylsealed sealed ring 5 is set to
Two, heat-generating pipe 3 is made up of electrode 7, heating wire 9 and Heat Conduction Material 10.
The sealing principle of this utility model heater is: two polytetrafluoroethylsealed sealed rings 5 are arranged in outside sealed base 4 and are enclosed within heating
On pipe 3, and crossing tight fit with the outer wall of heat-generating pipe 3 and the inwall of three way cock 2, clamp nut 6 is hollow structure, heating
Pipe 3 therethrough, extrudes polytetrafluoroethylsealed sealed ring 5 by screwing clamp nut 6 so that polytetrafluoroethylsealed sealed ring 5 further with heat-generating pipe 3
The inwall of outer wall and three way cock 2 compresses further, thus realizes high-pressure fluid seal.Heat-generating pipe 3 structure such as accompanying drawing 2 institute
Showing, being mainly made up of electrode 7, heating wire 9 and Heat Conduction Material 10, wherein electrode 7 should retain enough length so that heating
Device seals position does not has heating wire to generate heat, thus ensures that encapsulant temperature is unlikely to too high.Additionally due to this utility model heating
The voltage endurance capability of device depends on thickness and the performance of three way cock 2 of outer tube 1, therefore uses thick-walled seamless steel pipes and three way cock
The maximum working pressure of heater can be effectively improved.
