Problems solved by technology

[0004] This type of existing explosion-proof electric heater has a large heat loss in use. The first reason is that each casing passes through multiple electric heating devices, and there is a large gap inside, so the medium fluid entering it will form a convection cycle, not only The heat insulation effect is not good, and it affects the heat insulation; the second is that the water cooling takes away a lot of heat

Embodiment 1

[0014] The energy-saving explosion-proof electric heater of the present embodiment is as figure 2 Shown, one end of container body 5 is shaped on inlet 7, and the top is shaped on outlet 4, and the exterior coats aluminum silicate thermal insulation cotton 11 (making at the construction site usually). The explosion-proof chamber 13 is located at the other end of the container body 5, and a set of casing pipes 8 are fixedly welded between the two, and two isolation plates 1 distributed at intervals are welded and fixed between the casing pipes, which can strengthen the casing pipes. An air-cooled convection channel is also formed. The electric heating device 6 penetrates into the explosion-proof chamber 13 from the direction of the container body 5 (through the flange 3, the insulation cotton 2 and the isolation plate 1) through the sleeve 8, and each sleeve passes through a U-shaped electric heater The gap between one end of the device 6 is 0.5±0.1 mm, which can prevent the ...

Abstract

The present invention is improved explosion-proof electric heater and belongs to the field of electric heater technology. The electric explosion-proof heater has one container with inlet, outlet and outer coating heat insulating material; one explosion-proof chamber communicated through welded casings; and one electric heating device inside the container and with leads through the explosion-proof chamber. The improved explosion-proof electric heater has leads penetrating different casings separated by 0.5 mm, and this can avoid the convection of fluid medium in between, reduce heat loss and save electric power.

Description

technical field [0001] The invention relates to an explosion-proof electric heater, in particular to an improvement of an explosion-proof electric heater sleeve heat insulation structure, which belongs to the technical field of electric heating facilities. Background technique [0002] The function of the existing explosion-proof electric heater is to heat fluid media such as hydrogen and oil. Its typical structure is as follows: figure 1 As shown, the cylindrical container body 5 is formed with an inlet 7 and an outlet 4, and the outside is covered with an insulating material 11, and an explosion-proof chamber 13 is installed at one end, and the explosion-proof chamber 13 and the container body 5 are fixed by a set of sleeves 8 Welding, the electric heating device 6 penetrates into the container body 5 from the explosion-proof chamber 13 through the sleeve 8 , and the wire passes from the explosion-proof chamber 13 into the end of the electric heating device 6 . When worki...
