Description
Technical field
The present invention relates to electric heater technical field.
Background technology
Electric heater is mainly used in industry and the occasions such as oil, petrochemical industry, natural gas, chemical industry, electric power, metallurgy, machinery, medicine, food and civilian fire line, current heater has the disadvantage in that 1) medium directly heats by heater, and some Organic substance hot-spot can make medium generation coking；For stove, tile is heavy and thermal resistance is big；2) having the highest situation of pressure in operating mode to occur, the requirement to pressure vessel is the highest；3) heating element heater interts multiple parts, and is welded as a whole, and overhauls extremely difficult, and heating element heater once damages heater and is equal to scrap.
Summary of the invention
Present invention aim at a kind of energy-conserving and environment-protective being provided for disadvantages described above, reducing cost, the easy to maintenance and radial type explosion proof electric heater of the raising thermal efficiency.
The present invention includes cylinder, above described cylinder weld upper cover, below cylinder Flange joint low head, described upper cover, cylinder and low head be internally formed burner hearth；Inwall at described burner hearth is close to arrange heat-insulation layer, and described heat-insulation layer includes rock wool heat-preservation layer and is arranged on the aluminium silicate heat-insulation layer inside rock wool heat-preservation layer；Internal stent is set inside described burner hearth, described internal stent arranges metal coil pipe, between described metal coil pipe and aluminium silicate heat-insulation layer, is provided with gap；The upper end of described metal coil pipe connects media outlet, and lower end connects medium entrance, and described media outlet and medium entrance are separately positioned on the bottom of low head；
Arranging nitrogen inlet in side, described cylinder top, on described cylinder top, opposite side arranges nitrogen outlet；One end of described nitrogen inlet connects self-supporting regulation valve, in the other end is set in heat-insulation layer and connects with the top of burner hearth；One end of described nitrogen outlet connects single breathing valve, and the pipeline between single breathing valve and cylinder is also connected with hand-operated valve, in the other end is set in heat-insulation layer and connects with the bottom of burner hearth；
The uniform some pack support assemblies of circumference on described heat-insulation layer, described every pack support assembly includes that the potter's clay support that at least two-layer is the most uniform, one end of described every potter's clay support are plugged in heat-insulation layer respectively respectively；Difference resistance wire the most around the home on described every pack support assembly；Being provided above explosion-proof wiring chamber at described upper cover, described explosion-proof wiring chamber is connected with resistance wire.
The present invention is compared with heater, and homogeneous temperature, and the material avoiding easy coking directly contacts with thermal source, and pressure fixing is on pipeline, the requirement of container reduces, and provides cost savings；Compared with stove, heating wire without being placed in tile, exposed radiation, improve the thermal efficiency, energy-conserving and environment-protective, without tile, body of heater weight saving.This product combines every advantage of pressure vessel, electric heater, stove, comprehensive one.Main structure formula flange form of the present invention connects, detachably, during run into the parts of damage can be with separate repair, replacing, the especially damage of consumable accessory heating wire, because it is exposed in burner hearth, if the most conveniently replaced.The present invention uses insulation potter's clay, high temperature resistant, high insulation, light weight, and the mode that insulation potter's clay uses screw thread to insert injects aluminosilicate material, either assembles or maintenance, the most convenient and reliable.The present invention connects explosion-proof wiring chamber, can be used for explosion-proof place.
The present invention arranges tube wall thermometric, burner hearth thermometric on upper cover, to facilitate observation metal coil pipe and burner hearth internal temperature.
The present invention arranges resistance wire thermometric in cylinder side, to facilitate observation wire temperature.
The present invention arranges medium thermometric on the pipeline of media outlet, to facilitate observation medium temperature.
