Description
Technical field
The utility model relates to working medium heater, in particular, relates to a kind of compact organic working medium HTHP electric heater.
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 thermal radiation.
When adopting recirculation heater, reach higher operating pressure, heater housings, seal, link 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 overall heat exchange coefficient 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 compact organic working medium HTHP electric heater, 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 compact organic working medium HTHP electric heater, comprise heat-generating pipe, described heat-generating pipe is arranged at the inside of bringing-up section outer tube, what the two ends of described bringing-up section outer tube were symmetrical is provided with bump joint, what the bringing-up section outer tube left and right sides was corresponding is provided with pedestal, the binding post inserting bringing-up section outer tube and be connected with described heat-generating pipe is provided with in described pedestal, described binding post upper end is connected with external power supply, mica post is disposed with from top to bottom in pedestal, cylindrical section, mica post, sealing ring and hollow nut, insulating sleeve is provided with outside described cylindrical section He inside hollow nut.
End, described heat-generating pipe two ends is provided with the heating wire being arranged in heat-generating pipe inside by ceramic plug, be filled with magnesia between described heating wire and heat-generating pipe.
Described bringing-up section outer tube is made up of stainless steel riffled tube.
Described pedestal is internal thread seat.
Described insulating sleeve is ceramic insulation sleeve pipe.
Described sealing ring is polytetrafluoroethylsealed sealed ring.
Described binding post is steel axle.
Described sealing ring and binding post, pedestal are interference fit.
Compared with prior art, the beneficial effect that the technical solution of the utility model is brought is:
1. compare with existing circulating heater, the actual internal area of the utility model heater is relatively little, fluid velocity is fast, and employing is the female outer tube of tool, fluid turbulent disturbance can be strengthened, strengthen heating further, therefore, under identical heat exchange power, heat exchange area less than circulating heater many, therefore structure is compacter.
2. bringing-up section outer tube of the present utility model perforate is few, and presses ptfe ring by nut and more easily realize high pressure sealing.
3. the utility model is also provided with heat insulation mica layer and accelerates the cylindrical section of heat radiation, can be implemented in the situation lower seal that fluid temperature (F.T.) exceedes PTFE limiting temperature also can not lose efficacy, by lengthening the intermediate radiator part of binding post, the sealing of higher temperature can be realized.
4. the utility model is compared with the mode of external heat, with the obvious advantage in the efficiency of heating surface, heat exchange area etc.

Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1 to Figure 3: a kind of compact organic working medium HTHP electric heater, comprise heat-generating pipe 1, the inside of heat-generating pipe 1 is equipped with heating wire 13, the end, two ends of heat-generating pipe 1 is then provided with for the ceramic plug 14 sealed and insulate, be equipped with screw thread in the interstitial hole of pottery plug 14 with on outer surface, for being threaded with the connector lug of heat-generating pipe 1 and heating wire 13, and the inside of heat-generating pipe 1 is filled with the magnesia 15 of high-quality, magnesia 15 is filled by dress powder machine, and ensures compacting;
Heat-generating pipe 1 is arranged on the inside of bringing-up section outer tube 2, bringing-up section outer tube 2 is made up of stainless riffled tube, to strengthen the disturbance of internal flow, increase convection transfer rate, what the two ends of bringing-up section outer tube 2 were symmetrical is provided with bump joint 5, and the left and right sides of bringing-up section outer tube 2 corresponding be provided with pedestal 3, pedestal 3 is internal thread seat, be welded on the outer wall of bringing-up section outer tube 2, the inner hub location place of pedestal 3 is provided with the binding post 4 inserting bringing-up section outer tube 2 inside, binding post 4 is made up of steel axle, binding post 4 the latter half is thinner, the first half is then thicker, the top of binding post 4 is connected with external power supply, mica post 6, cylindrical section 7, mica post 8, sealing ring 9 and hollow nut 10 is disposed with from top to bottom in pedestal 3, sealing ring 9 is polytetrafluoroethylsealed sealed ring, the arranged outside of cylindrical section 7 has insulating sleeve 12, the inner side of hollow nut 10 is provided with insulating sleeve 11, and insulating sleeve 11 and insulating sleeve 12 are ceramic insulation sleeve pipe.After heat-generating pipe 1 is energized, insulating sleeve 11, insulating sleeve 12 realizes the insulation of binding post 4 and hollow nut 10 and pedestal 3, the heat insulation mica layer that mica post 6 and mica post 8 are formed can reduce the heat transfer of internal high temperature fluid to wiring part, thus guarantee is being no more than its limiting temperature (about 250 degrees Celsius) by the temperature adding the situation lower sealing ring 9 of hot fluid high temperature, sealing ring 9 is interference fit with binding post 4 and pedestal 3, hollow nut 10 realizes the sealing to high-pressure fluid under the effect of pretightning force after tightening, the surface area of cylindrical section 7 is larger, therefore can outwards be dispelled the heat by the insulating sleeve 12 of thin-walled preferably, greatly be reduced by the heat transmission of binding post 4 upwards (hermetic unit), the temperature of further reduction sealing ring 9, in addition the fineness of binding post 4 top and the bottom is increased, cooling-down effect can be more remarkable.In addition the part that mica post 6 and bringing-up section outer tube 2 outer wall are pressed close to has an outstanding little ring, is used for filling the gap between steel axle and tube wall perforate.
