Description
Technical field
The utility model relates to working medium heater, in particular, relates to a kind of organic working medium high-temperature and pressure pipeline formula electric heater.
Background technology
Present 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 that a kind of structure is simple, cost-saving, the efficiency of heating surface is high, the organic working medium high-temperature and pressure pipeline formula electric heater of safe and reliable, accurate temperature controlling.
The purpose of this utility model is achieved through the following technical solutions:
Organic working medium high-temperature and pressure pipeline formula electric heater, described electric heater comprises heating section outer tube and wire barrel, heat-generating pipe is provided with in described heating section outer tube, 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; Be fixedly connected with binding post by support, the connection that described heat-generating pipe is corresponding with described binding post in described wire barrel, described heating section outer tube and wire barrel pass through the symmetrical connection of flange.
Described heating section outer tube and wire barrel are inner is correspondingly respectively provided with 4 heat-generating pipes and binding post.
Described heating section outer tube and wire barrel pass through the symmetrical connection of 2 pairs of flanges.
The 2 pairs of flanges be provided with for being connected with exterior tubing also symmetrical on described wire barrel.
The surfaces externally and internally of described ceramic plug is provided with screw thread.
The pad of described flange, bolt washer and bolt sleeve are insulating material.
Described support is made up of the Metallic rod being symmetrically distributed in wire barrel inwall.
Described support adopts the connected mode of welding with binding post.
Compared with prior art, the beneficial effect that the technical solution of the utility model is brought is:
1. heater outer tube of the present utility model is whole seamless steel pipe, and surface does not have perforate, is connected, therefore more easily bears higher pressure by means of only flange with outside.Simultaneously because actual internal area is relatively little, flow velocity is very fast, and heat exchange coefficient is larger, and under same power, heat exchange area is less.
2. do not arrange baffler in the utility model and sectional area is constant, therefore pressure loss relative cycle formula heater is little; And compare with external heating type heater, the heat efficiency is higher, and thermal protection, isothermal holding are simpler.
