Description
Technical field
The invention belongs to the electric-heating technology field, relate to a kind of high-pressure gaseous, liquid medium electric heater for heating.
Background technology
Usually, circulation heater is selected in the heating of industrial gaseous state, liquid medium for use.Its basic functional principle is: heated medium circulates under certain pressure; Through heating work chamber-vessel shell; Obtain sealing the heater element that is inserted in the heating work chamber with conduction, convection current form of heating regime; Therefore, the housing in heating work chamber and heater element are all worked under certain pressure and temperature.When heated medium was in high pressure conditions, for safety, its structure bearing requirements increased substantially as the housing of pressure vessel and heating element heater, and manufacture difficulty strengthens, and causes ultimate cost to promote significantly.This has just restricted the application of circulation heater under gases at high pressure, liquid medium operating mode greatly.
Summary of the invention
Technical problem to be solved by this invention is that providing a kind of can heat gaseous state, liquid medium under the high pressure conditions, the high-pressure gaseous liquid medium electric heater for heating that bearing capacity is strong.
Gaseous, liquid medium of the present invention comprises one section spiral helicine metal coil pipe with electric heater; The two ends of metal coil pipe are the entrance and exit for supplying heated medium to get into and flow out; In the spiral inner chamber of spiral coil, vertically be inserted with a plurality of electric heating tubes; Electric heating tube is evenly arranged and is close to the spiral internal diameter wall along the spiral internal diameter wall of metal coil pipe; Metal coil pipe and electric heating tube are cast in by containing in the matrix of a metal casting body, and the entrance and exit of the terminals of electric heating tube and metal coil pipe stretches out the metal casting body.
Said metal casting body is a tubulose.Inner cylinder face, external cylindrical surface and the bottom surface of the metal casting body of tubulose is covered by in the cannelure of being processed by steel plate.The metal casting body inboard and the outside at tubulose are provided with the heat-insulation layer of having filled heat-insulating material.Heat-insulation layer outer surface in the periphery is coated with metal shell.Metal shell seals fully, to be suitable for outdoor application.
The terminals of said electric heating tube are housed in the terminal box.Also be provided with overtemperature protection device in the terminal box, the temperature sensor of overtemperature protection device stretches into the metal casting body and abuts against on the metal coil pipe near the outlet position.
Advantage of the present invention is:
1, expensive vessel shell need be set as the heating work chamber, reduce equipment cost;
2, metal coil pipe, electric heating tube and metal casting body are cast into an entity, and the heating of electric heating tube can fast and effeciently be conducted to the medium in the metal coil pipe, have improved heat efficiency;
3, the cast-in-block structure has strengthened the bearing capacity of metal coil pipe and electric heating tube greatly, enables to be applicable to high pressure conditions (the heated medium operating mode of P >=10MPa).
4, simple in structure, install firm, easy to use.
