Abstract
The invention discloses a heating core heat insulation structure. The electric heating tube is positioned and installed through a plurality of supporting pieces, a heat insulation barrel is arranged between the electric heating tube and the container, the heat insulation barrel is welded and fixed on the periphery of the supporting pieces, the heat insulation barrel leaves the medium inlet and enables a heated medium to flow in from the medium inlet, and then the heated medium is heated through the electric heating tube in the heat insulation barrel. After adopting above-mentioned structure for the medium temperature improves, and the high temperature heat that electric heating pipe distributed out is blockked by thermal-insulated barrel simultaneously, makes the temperature that transmits the container inner wall reduce, has reached and has reduced container design service temperature, has attenuate the thickness of container and has improved security and life, has still saved energy and material cost, thereby has adapted to and has reduced the requirement that the temperature that the heating pipe surface transmitted to the container casing under the higher condition of heating medium temperature.
Description
Technical Field
The invention relates to a circulating heater structure, in particular to a heating core heat insulation structure.
Background
Under the general condition, circulating heater structure designs with reference to GB151 heat exchanger, but the heater is different from the heat exchanger again, the heating pipe body is at the heat that does not stop giving off, and the temperature on heating pipe surface can be too much than heating medium temperature under the lower condition of flow, and the heating pipe is nearer apart from the container casing, generally about 8~12mm apart from the casing is inboard, high temperature can transmit the casing surface, under the container casing according to GB150 and the condition of TSG21-2016 design, just need to improve the design temperature, thereby cause container casing thickness increase, the flange grade improves, more serious can cause former design material to be unusable, the material cost has been led to and has been increased, be unfavorable for energy-conservation, product competitiveness descends, container life reduces scheduling problem.
Disclosure of Invention
The invention aims to provide a heating core heat insulation structure which can reduce the temperature of the inner wall of a container, thereby reducing the thickness of the container, reducing the material cost, prolonging the service life and saving energy.
In order to solve the technical problem, the heating core heat insulation structure comprises a container with a medium inlet and a medium outlet and an electric heating pipe positioned in the container, wherein the electric heating pipe is positioned and installed through a plurality of supporting pieces, a heat insulation barrel is arranged between the electric heating pipe and the container and is welded and fixed on the periphery of the supporting pieces, and the heat insulation barrel is away from the medium inlet and can enable a heated medium to flow in from the medium inlet and further heats the heated medium through the electric heating pipe in the heat insulation barrel.
The heat insulation cylinder body and the support piece are fixed in a plug welding mode.
The heat insulation cylinder body is close to the medium outlet and the length of the heat insulation cylinder body is less than that of the electric heating pipe, so that the medium inlet is avoided.
The heat insulation barrel is formed by rolling a thin plate.
The outer surface of the heat insulation barrel is provided with longitudinal fixing rods which are distributed along the axial direction of the outer surface of the heat insulation barrel in an annular mode and fixing rings which are distributed along the circumferential direction of the outer surface of the heat insulation barrel.
The medium inlet is arranged on the side wall of the container, the medium outlet is arranged at the tail of the container, and the head of the container is provided with a junction box.
After adopting foretell structure, because a plurality of support piece that set up carry out the electric heating pipe of location installation and welded fastening at the peripheral thermal-insulated barrel of support piece and thermal-insulated barrel lets away the medium import, can make from this that heated medium flows in from the medium import, and then the electric heating pipe through in the thermal-insulated barrel heats, make the medium temperature improve, the high temperature heat that electric heating pipe distributes out is blockked by thermal-insulated barrel simultaneously, make the temperature that transmits to the container inner wall reduce, reached and reduced container design service temperature, the thickness of attenuate the container and improved security and life, energy and material cost have still been saved, thereby the requirement of the temperature that reduces the heating pipe surface and spread to the container body under the higher condition of heating medium temperature has been adapted to.
