Description
Technical field
The present invention relates to duct type electrothermal device, specifically, relate 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, and external heating mode mainly has heating furnace, Electromagnetic Heating, heat-conducting oil heating etc..Circulating heater adopts metal shell to surround heater element and heated fluid, and power is relatively big, the highest can pressure 20Mpa, most high-temperature resistant 600 DEG C.The heat convection that heat-conducting oil heating mostly is outside by pipe is heated, and fluids within pipes is heated by heating furnace by heat radiation.
When adopting recirculation heater, reach higher operating pressure, heater housings, sealing member, connection member needs bigger size, equipment often becomes very heavy, investment increases, and recirculation heater generally adopts 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 is through recirculation heater, suddenly become big due to passage, air deflector flows to transfers, therefore when fluid velocity is bigger, the pressure loss is relatively larger, recirculation heater is safeguarded more complicated, more difficult maintenance after heat-generating pipe damage inside heater.And external heat equipment is often because thermal diffusion causes that the efficiency of heating surface is not high, and because the overall coefficient of heat transfer is low, faces the problem such as high temperature protection, insulation, easily go out security incident.Such as, heat-conducting oil heating, generally require very big heat-conducting oil heating recycle unit.Heating furnace radiation heat transfer then efficiency is lower, and thermal diffusion is serious.Electromagnetic heater is not then suitable for accurate temperature and controls occasion, and accurate temperature controlling needs other auxiliary equipment, and radiation faces more greatly non-controllable risk.
Summary of the invention
The advantages such as the invention aims to overcome deficiency of the prior art, it is provided that cryogenic high pressure duct type electrothermal device in one, this heater has compact conformation, and efficiency is high, safe and reliable.
It is an object of the invention to be 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 heat-generating pipe, what the two ends of described outer tube were symmetrical is fixedly connected with three way cock, it is provided with sealed base in described three way cock, the circular hole for fixing described heat-generating pipe it is provided with in the middle part of described sealed base, the clamp nut being orderly arranged outside each polytetrafluoroethylsealed sealed ring and hollow of described sealed base, described polytetrafluoroethylsealed sealed ring is provided with at least two, and described heat-generating pipe is made up of electrode, heating wire and Heat Conduction Material.
Outer wall and the three way cock of described polytetrafluoroethylsealed sealed ring and described heat-generating pipe were tight fit.
The external diametrical extent of described outer tube is 18-25mm.
Compared with prior art, technical scheme is had the benefit that
1. compared with circulating heater compare, the bearing capacity of heater of the present invention depends primarily on the thickness of seamless steel pipe and the sealing property of polytetrafluoroethylsealed sealed ring, therefore can bear higher pressure under 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, and therefore relative to conventional heater, the thermal resistance between heat-generating pipe and fluid is greatly reduced, thus improve the efficiency of heat exchange, and then reduces heat exchange area.
3. heater of the present invention is safeguarded very simple, after heat-generating pipe or sealing ring damage, by unscrewing clamp nut, is extracted out by heat-generating pipe, it is easy to carry out the replacing of polytetrafluoroethylsealed sealed ring or heat-generating pipe.
4. what heater outer tube adopted is the external diameter seamless steel pipe less than 25mm, entirety is compacter, it is easier to be arranged in the tubing of complexity, additionally due to the inside of heater outer tube is straight channel, the pressure loss of fluid is only small, therefore relative to circulating heater, it is more applicable for high-velocity fluid.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As 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, the external diameter of outer tube 1 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, sealed inside high-pressure fluid, and connects exterior line by nipple 8.Sealed base 4 it is provided with in three way cock 2, sealed base 4 and three way cock 2 are structure as a whole, the middle part of sealed base 4 is provided with the circular hole for fixing heat-generating pipe 3, the clamp nut 6 being orderly arranged outside each polytetrafluoroethylsealed sealed ring 5 and hollow of sealed base 4, in the present embodiment, polytetrafluoroethylsealed sealed ring 5 is set to two, and heat-generating pipe 3 is made up of electrode 7, heating wire 9 and Heat Conduction Material 10.
The sealing principle of heater of the present invention is: two polytetrafluoroethylsealed sealed rings 5 are arranged in outside sealed base 4 and are enclosed within heat-generating pipe 3, and cross 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, heat-generating pipe 3 is therethrough, polytetrafluoroethylsealed sealed ring 5 is extruded by screwing clamp nut 6, polytetrafluoroethylsealed sealed ring 5 is compressed further further, thus realizing high-pressure fluid seal with the inwall of heat-generating pipe 3 outer wall and three way cock 2.Heat-generating pipe 3 structure as shown in Figure 2, is mainly made up of electrode 7, heating wire 9 and Heat Conduction Material 10, and wherein electrode 7 should retain enough length so that heater seals position does not have heating wire to generate heat, thus ensureing that encapsulant temperature is unlikely to too high.Additionally due to the voltage endurance capability of heater of the present invention depends on the thickness of outer tube 1 and the performance of three way cock 2, therefore adopt thick-walled seamless steel pipes and three way cock can be effectively improved the maximum working pressure of heater.
