Abstract
The utility model belongs to an electrical heating device, in particular to a medium circulating electrical heating unit and a multilevel serial medium circulating electrical heater for heating gas state or liquid state medium. The medium circulating electrical heating unit comprises a heating cavity with a U-shaped pipe structure with the same section, which is formed of two straight pipes and a bent pipe, wherein a medium inlet is arranged on the position near the end of one straight pipe, a medium outlet is arranged on the position near the end of the other straight pipe, and a group of electrical heating cores are respectively inserted into the two straight pipes in a sealing mode, thereby the two straight pipes form a two-stage circulating heating cavity. The unit can heat the gas state or the liquid state medium with a multi-stage circulating mode, and the pressure loss of the medium during the multi-stage circulation is less.
Description
Technical field
The utility model belongs to electric heater unit, relates to a kind of medium circulation electric heater unit and combination of plural serial stage medium circulation electric heater that gaseous state or liquid medium are heated of being used for.
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, by heating work chamber-vessel shell, obtain one sealed be inserted in the heating work chamber heater element with the conduction, to streamed heating.Because the heating structure arranges, the restriction of security reliability and manufacturing process, accomplish to reach by an electric heater heating of the big temperature difference of medium, difficulty is very big.The electrical heating core is done to such an extent that power is excessive in finite size on the one hand, will spend the surface loading that improves electric heating tube greatly, the reliability and the life-span of directly reducing electric heating tube, even cisco unity malfunction; On the other hand, manufacturing process can't guarantee the quality and the uniformity of electric heater, and cost increases substantially.The scheme of common solution is to adopt a plurality of circulation heater with outlet(discharge) flange next stage electric heater suction flange to be connected in series step by step by heating-up temperature.This structure is because the less and flange connection of import and export caliber produces bigger damping, and the pressure loss is bigger, also influenced the flow regime of gaseous state, liquid medium.
Summary of the invention
Technical problem to be solved in the utility model is, providing a kind of can carry out big temperature difference heating to gaseous state or liquid medium with multistage endless form, and the medium medium circulation electric heater unit that the pressure loss is little in multistage cyclic process and be the plural serial stage medium circulation electric heater combination of part with this electric heater unit.
The utility model medium circulation electric heater unit includes the heating chamber of the prismatic U-shaped tubular construction that is formed by connecting by two sections straight tubes and one section bend pipe, be provided with the medium import in position near the straight-run of pipe end, be provided with media outlet in position near another section straight tube end, sealing is inserted with one group of electrical heating core respectively in two sections straight tubes, makes two sections straight tubes constitute two-stage circulation heating chamber.
The medium circulation electric heater that above-mentioned medium circulation electric heater unit can directly heat as a two-stage uses, also can constitute plural serial stage medium circulation electric heater combination of the present utility model behind the plural serial stage, its structure comprises a plurality of above-mentioned medium circulation electric heater unit, each medium circulation electric heating unit is connected mutually, promptly directly connects as one by direct piping between the medium import of back one-level medium circulation electric heating unit and the previous stage medium circulation electric heating unit.
Plural serial stage medium circulation electric heater combination of the present utility model can also be connected mutually with the combination of medium circulation electric heater by above-mentioned medium circulation electric heater unit and be constituted, that is, medium import and the previous stage medium circulation electric heater of the combination of back one-level medium circulation electric heater unit or medium circulation electric heater make up or the media outlet of medium circulation electric heater unit between be connected by flange is firm.
In the utility model structure, the two-stage heating chamber of medium circulation electric heating unit has reduced the pressure medium loss by prismatic bend pipe connection, has improved efficient; And in the plural serial stage medium circulation electric heater of the present utility model, directly connect by direct piping between the multistage electric heating unit, in the heating step by step that realizes gaseous state, liquid medium, guaranteed less pressure medium loss and higher efficient equally.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the plan structure schematic diagram of Fig. 1;
Fig. 3 is that the A of Fig. 1 is to structural representation.
The specific embodiment
As shown in the figure, comprise an electric heater D1 and a medium circulation electric heater combination D2 who constitutes by two medium circulation electric heater unit 1 who constitutes by single medium circulation electric heating unit 1 among the embodiment of the present utility model.D1 and D2 constitute the combination of plural serial stage medium circulation electric heater jointly.
Each medium circulation electric heater unit 1 comprises the heating chamber of the prismatic U-shaped tubular construction that is formed by connecting by two sections straight tubes 11 and one section bend pipe 12, be provided with medium import 13 in position near the straight-run of pipe end, be provided with media outlet 14 in position near another section straight tube end, sealing is inserted with one group of electrical heating core 15 respectively in two sections straight tubes 11, makes two sections straight tubes constitute two-stage circulation heating chamber.
Directly connect as one by direct piping 2 between the medium import of one-level medium circulation electric heater unit, back and the previous stage medium circulation electric heater unit in the medium circulation electric heater combination two-stage medium circulation electric heater unit 1 that D2 had in the accompanying drawing illustrated embodiment.And the inlet of whole medium circulation electric heater combination D2 is connected by flange 4 with the outlet of electric heater D1, constitutes a plural serial stage medium circulation electric heater combination, and is installed on the common support 3.
