Abstract
The invention relates to an electrical heater for heating a gas state or liquid state medium containing solid particle matters, belonging to the field of electrical heating device and comprising a medium heating work room and at least one electrical heating core, wherein the electrical heating core is inserted into the medium heating work room and comprises a plurality of electrical heating pipes which are arrayed on a flange cover in a clustering way and fixedly arranged on the flange cover and a plurality of temperature measuring pipes which are distributed within a heating range of the electrical heating pipes and connected with an overtemperature protection circuit. The electrical heater is characterized in that the electrical heating pipes and the temperature measuring pipes are accommodated in a thin-walled metal drum, one end of the thin-walled metal drum is hermetically connected with the flange cover, the other end of the thin-walled metal drum is closed, and gaps between the inner wall of the thin-walled metal drum and the electrical heating pipes and between the inner wall of the thin-walled metal drum and the temperature measuring pipes are filled with cast aluminium casting bodies. The electrical heater can heat the gas state or liquid state medium containing the solid particle matters, and a temperature measuring point of the overtemperature protection of the electrical heater can accurately feed back the temperature state of the integral electrical heating core, thereby preventing damage because of the partial overheating of a part of the electrical heating pipes.
Description
Technical field
The invention belongs to electric heater unit, specifically is a kind of be used for the heating gaseous state that contains solid particulate matter or electric heater of liquid medium.
Background technology
Usually, the circulation heater that the heating of industry gaseous state, liquid medium is selected for use, its basic structure and operation principle are that one or more electrical heating core sealings that are made of boundling arrangement electric heating tube are inserted in the medium heating work chamber-vessel shell, heated medium circulates under certain pressure and passes through housing, the heater element heating power of electrical heating core, and to conduct, to streamed medium to be heated.But when heated medium is gaseous state, the liquid medium that is mixed with a certain amount of solid particulate matter, it always has the solid particulate matter deposition when circulating by housing under certain pressure.And the solid particulate matter non-conductor of heat normally, this solid particulate matter deposition increases with the continuity of working time, finally wraps electric heating tube, can't be dispelled the heat in its part and temperature is too high.Because the overtemperature prote thermometric can only be that individual bits installs, when by local the no overtemperature prote thermometric of the electric heating tube of solid particulate matter deposition parcel, then this electric heating tube will hot-spot and early stage scaling loss makes whole electric heater damage, causes heavy losses.
Summary of the invention
Technical problem to be solved by this invention is; provide a kind of and can heat the gaseous state that contains solid particulate matter or the electric heater of liquid medium; make the point for measuring temperature of its overtemperature prote can accurately feed back the state of temperature of whole electrical heating core, with the damage of avoiding causing because of part electric heating tube hot-spot.
Electric heater of the present invention includes medium heating work chamber (container casing) and is inserted at least one indoor electrical heating core of medium heating work; described electrical heating core includes boundling and arranges and be fixedly mounted on a plurality of electric heating tubes on the blind flange and be distributed in several interior temperature tubes that are connected with the overtemperature prote circuit of electric heater for heating scope; it is characterized in that; all electric heating tubes and temperature tube are inclusive in the metal cylinder of a thin-walled; metal cylinder one end and blind flange are tightly connected; the sealing of the metal cylinder other end, the gap between metal cylinder inwall and electric heating tube and the temperature tube is full of by the cast aluminium body of casting.
Described electrical heating core has a plurality of, organizes the electrical heating core more and is connected in parallel, can control respectively by the control circuit of outside, thereby realize the electrical heating core one by one, part or all of heating power.
Advantage of the present invention is:
1. the heat generating component integral structure of electrical heating core and the fabulous thermal conductivity of cast aluminium body; realized that thermograde is very little in the heat generating component; guarantee that the solid particulate matter that is deposited on the non-conductor of the conduct heat in the vessel shell in thin-wall metal tube outer surface part wraps up; when stoping the exchange of heat generating component and medium heat; the overtemperature prote temperature tube that the electrical heating in-core is provided with is normal thermometric all the time; still can normally realize the overtemperature power-off protection, heater is not burnt.Therefore, this electric heater has solved the gaseous state that solid particulate matter is arranged, the difficult problem of liquid medium heating.
2. the heat generating component integral structure of electrical heating core, bearing capacity is big, has guaranteed the functional reliability under the high-pressure medium operating mode; Thin-wall metal tube and end socket adopt the good material of corrosion resistance, have guaranteed the working life under the strong corrosive medium operating mode.
3. because the electrical heating core contacts just closed cylinder with medium, can take out and remove the deposition solid particle easily in vessel shell, insertion can be resumed work rapidly after installing again.
4. in a heating work chamber-vessel shell, insert the electrical heating core of one or more parallel connections simultaneously from the housing axial direction, realize the big and compact conformation of general power, simultaneously, each electrical heating core power can reduce relatively, has reduced manufacture difficulty and control difficulty.

The specific embodiment
As shown in the figure; this electricity receipt device includes medium heating work chamber 1 and is inserted at least one indoor electrical heating core 2 of medium heating work; the electrical heating core includes boundling and arranges and be fixedly mounted on a plurality of electric heating tubes 22 on the blind flange 21 and be distributed in several interior temperature tubes 23 that are connected with the overtemperature prote circuit of electric heater for heating scope; all electric heating tubes 22 and temperature tube 23 are inclusive in the metal cylinder 24; metal cylinder one end and blind flange 21 are tightly connected; the sealing of the metal cylinder other end, the gap between metal cylinder inwall and electric heating tube and the temperature tube is full of by the cast aluminium body 25 of casting.
Described electrical heating core 2 has a plurality of, and a plurality of electrical heating cores are connected in parallel by binding post separately.
Claims (2)
