Technical field
The utility model relates to working medium heater, in particular, relates to a kind of organic working medium electric heater for low discharge high-velocity fluid.
Background technology
Organic working medium heater can be divided into external heat and interior heating two kinds of modes at present.Interior firing equipment mainly contains recirculation heater, and external heating mode mainly contains heating furnace, Electromagnetic Heating, heat-conducting oil heating etc.Circulating heater adopts metal shell to surround heater element and added hot fluid, and power is comparatively large, the highest can withstand voltage 20Mpa, most high-temperature resistant 600 DEG C.Heat-conducting oil heating mostly is and is heated by the heat convection outside pipe, and heating furnace is heated fluids within pipes by heat radiation.
When adopting recirculation heater, reach higher operating pressure, heater housings, seal, attaching parts need larger size, equipment often becomes very heavy, investment increases, and recirculation heater adopts silica gel and ceramic seal usually, and common silica gel will lose efficacy when more than 300 degrees Celsius, and more resistant to elevated temperatures encapsulant faces the sharp increase in price, and fluid is through recirculation heater, due to circulation passage flip-flop, air deflector flows to transfers, and therefore the pressure loss is larger.And external heat equipment is often because thermal diffusion efficiency 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, often needs complicated conduction oil recycle unit.Heating furnace carries out the lower and equipment of heat exchange efficiency by radiation and takes up space greatly, 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 non-controllable risk more greatly.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of organic working medium electric heater for low discharge high-velocity fluid, and this heater has the advantages such as practicality and high efficiency, simple to operate, cost-saving, safe and reliable, high temperature high voltage resistant.
The purpose of this utility model is achieved through the following technical solutions:
A kind of organic working medium electric heater for low discharge high-velocity fluid, comprise heat-generating pipe, what the two ends of described heat-generating pipe were symmetrical is provided with triplet card bell and spigot joint, screw base is provided with in the landing edge of described triplet card bell and spigot joint, heat insulation loop is disposed with from top to bottom in described screw base, locating ring, sealing ring and hollow screw, joint pin is plugged with in described screw base, the upper end of described joint pin is connected with external power supply, the lower end of joint pin is set to hook-shaped, described hook is provided with the connector with heating wire, described heating wire is wrapped on the bolster that is flexibly connected with described connector.
The contact position of described screw base, hollow screw and joint pin is provided with insulating sleeve.
Described heat insulation loop is mica heat insulation loop.
Described sealing ring is polytetrafluoroethylsealed sealed ring.
Described joint pin is copper post.
Described heating wire is nickel filament.
Described bolster is made up of pottery.
Described bolster and connector are threaded connection.
Described connector is shape of a saddle joint.
Compared with prior art, the beneficial effect that the technical solution of the utility model is brought is:
1. the utility model is directly arranged in by heating wire in the fluid of heat-generating pipe inside, fluid directly washes away heating wire, therefore relative to conventional heater, thermal resistance between heating wire and fluid reduces greatly, thus improve the efficiency of heat exchange, and then reduce heat exchange area, heating wire is arranged in organic working medium simultaneously, be in the environment of absolute anaerobic, the service life of heating wire increases.
2. the triplet card bell and spigot joint of the utility model use is more convenient relative to conventional flange connected mode easy-to-use; The seamless steel pipe that heating element adopts, entirety is compacter, and be more easily arranged in complicated pipe-line system, heat-generating pipe inside is straight channel, and the pressure loss of fluid is very little, therefore relative to circulating heater, is more applicable for high-velocity fluid.
3. heat-generating pipe of the present utility model is made up of seamless steel pipe, and the voltage endurance capability of this heat-generating pipe and cutting ferrule is very strong, therefore can bear higher pressure under the prerequisite of lower cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1 to Figure 3: a kind of organic working medium electric heater for low discharge high-velocity fluid, comprise heat-generating pipe 1, the seamless steel pipe that heat-generating pipe 1 is no more than 25mm by external diameter is made, what the two ends of heat-generating pipe 1 were symmetrical is provided with triplet card bell and spigot joint 2, screw base 3 is provided with in the landing edge of triplet card bell and spigot joint 2, the inside of screw base 3 is disposed with heat insulation loop 4 from top to bottom, locating ring 5, sealing ring 6 and hollow screw 7, joint pin 9 is plugged with in screw base 3, joint pin 9 is made up of copper post, wherein screw base 3, hollow screw 8 is provided with insulating sleeve 7 with the junction of joint pin 9, heat insulation loop 4 is mica heat insulation loop, for reducing the heat conduction of direction of flow sealing ring 6, thus ensures that heater of the present utility model at high temperature can reliably working, the radius of locating ring 5 is less than the internal diameter of screw base 3, for axial location joint pin 9 and make connect fastening, avoid joint pin 9 to contact with screw base 3 simultaneously, sealing ring 6 is polytetrafluoroethylsealed sealed ring, is interference fit with the inwall of joint pin 9 and screw base 3, fits tightly under the pretightning force effect of hollow screw 8 with joint pin 9 and screw base 3 inwall, thus realizes sealing to heat-generating pipe internal high pressure fluid, insulating sleeve 7 is used for ensureing the insulation of joint pin 9 and screw base 3 and hollow screw 8.
The upper end of joint pin 9 is connected with external power supply, external power supply provides 220V alternating current, the lower end of joint pin 9 is set to hook-shaped, hook 10 is connected with the shape of a saddle connector 11 with heating wire 12, for facilitating installation and the replacing of inner body, heating wire 12 is nickel filament, and the two ends of connector 11 are threaded connection the bolster 13 be made up of pottery, heating wire 12 is wound around on bolster 13, thus heating wire 12 can not be contacted with the tube wall of heat-generating pipe 1.
In the utility model, the voltage endurance capability of this heater depends on the duct thickness of heat-generating pipe 1 and the performance of triplet card bell and spigot joint 2, and heavy wall and high-quality joint therefore by suitably improving the steel pipe of heat-generating pipe 1 effectively can improve the maximum working pressure of heater.When heater operating temperature is higher than 300 degrees Celsius, the thickness of heat insulation loop 4 should be increased with actual conditions, change the copper axle of joint pin 9 into steel axle, thus reduce the transmission of heat to sealing ring, to ensure that sealing ring can not lose efficacy, heating wire 12 adopts high-quality nickel filament to improve service life.
