Abstract
The utility model discloses a short-circuit type electric heating exchanger, wherein heating pipes are spirally arranged in a heating container; the heating pipes adopt a series-connection mode; the heating pipes are connected with a wiring copper bar; an external power supply adopts a heating mode of low voltage and large current by the heating pipes; the heating pipes are insulated with flanges by high-temperature-resistant ceramic pieces; a sealing head of the heating container is provided with a nitrogen filling port so as to carry out nitrogen-filling protection on the inside of the heating container, on one hand, the service leaves of the heating pipes are improved, and on the other hand, the short-circuit type electric heating exchanger can be used on the anti-explosion occasions. The short-circuit type electric heating exchanger has the advantages of reasonable structural design and capability of being used on the anti-explosion occasions and the like, solves the technical problems of easy scaling of temperature-sensitive medium in the heating process on, and improves the handling capability of products.
Description
Technical field:
The utility model patent relates to a kind of heat exchanger, particularly relates to a kind ofly to non-scaling, corrosion-resistant in the responsive to temperature medium heating process, and can use short-circuit type electrical heat exchanger in explosion-proof occasion.
Background technology:
Run into the highstrung heating occasion of temperature through regular meeting in heat exchanger field, the heating field of media such as p-methylphenyl dichlorosilane, propylene for example, these media are very responsive to temperature, but need heating, with traditional heat exchanger or electric heater because complex structure, fluid resistance are big, tend to cause the fouling or the coking of medium, can cause the obstruction of system in the heating process, even can cause the paralysis of system; To some heating occasions with Korrosionsmedium, heating-up temperature is very high in addition, adopts traditional circulation heater, because its heating tubular electrothermal element wall thickness very thin (being generally 1mm) do not have corrosion resistance, so service life is very short.
The utility model content:
The utility model provides a kind of to non-scaling, corrosion-resistant in the responsive to temperature medium heating process at the deficiencies in the prior art, and can use the heat exchanger in explosion-proof occasion.
For realizing above purpose, the technical solution adopted in the utility model is as follows:
The short-circuit type electrical heat exchanger is by heating tube, heating container, refractory ceramics spare, copper busbar, fill the nitrogen mouth and form; Heating tube helical arrangement in heating container wherein; adopt the mode that is connected in series between heating tube and heating tube; heating tube is connected with copper busbar; external power supply adopts the mode of heating of low-voltage and big electric current to heating tube by copper busbar; insulate by refractory ceramics spare between heating tube and flange, the heating container end socket is provided with and fills the nitrogen mouth, to carrying out nitrogen filled protection in the heating container; on the one hand the service life of improving heating tube, can use in explosion-proof occasion on the other hand.
The utlity model has following advantage: at first, external power supply makes heating tube heat soon, be not easy fouling in heating process by the mode of heating of copper busbar to heating tube employing low-voltage and big electric current; Secondly, heater housing end socket is provided with and fills the nitrogen mouth, to carrying out nitrogen filled protection in the heating container, improves the service life of heating tube, can use in explosion-proof occasion simultaneously.
Description of drawings:
Fig. 1 is the utility model overall schematic;
Fig. 2 is an A-A cutaway view among Fig. 1.
The specific embodiment:
The short-circuit type electrical heat exchanger is by heating tube 1, heating container 2, refractory ceramics spare 3, copper busbar 4, fill nitrogen mouth 5 and form; During concrete enforcement, heated medium enters from 1 one of heating tubes, flow out from heating tube 1 other end, external power supply makes medium heat soon, be not easy fouling at heating tube 1 in heating process by the mode of heating of 4 pairs of heating tubes of copper busbar, 1 employing low-voltage and big electric current; In to medium heating process, carry out nitrogen filled protection by filling 5 pairs of heating container 2 inside of nitrogen mouth, on the one hand the service life of improving heating tube 1, can use in explosion-proof occasion on the other hand.
The utlity model has reasonable in design, can use in advantages such as explosion-proof occasions, the responsive to temperature medium has been solved the technical problem of easy fouling in heating process, improved the disposal ability of product.
