Description
Technical field
The present invention relates to industrial process electric-heating technology field, especially a kind of electricity being suitable for gas heating occasion adds
Hot device.
Background technology
Existing industrial electric heating device is in a kind of container of band inlet and outlet frequently with the structure of circulation heater
It is inserted into boundling electrothermal tube structure.Boundling heater is that a large amount of electrothermal tube is welded on one block of process flange plate.The master of the structure
Wanting defect is：
1, since in process fluid flow, fluid is flowed along the direction of electrothermal tube, and the turbulent flow effect of generation is undesirable, changes
Hot coefficient is low, and electrothermal tube surface temperature and internal heating wire's temperature are high, electrothermal tube short life.
2, due to being limited to by electric heating pipe processing technique, along the direction of fluid flowing, electrothermal tube tube wall temperature is uneven,
It is higher more to arrive outlet electrothermal tube temperature, can also influence the service life of electrothermal tube.
3, maintenance difficult, if certain electrothermal tube damages, it usually needs terminal box is sawed down, even to be needed surrounding sometimes
Electrothermal tube also to dismantle.
Invention content
The technical problem to be solved in the present invention is to provide a kind of industrial process electric heaters, can reduce the table of electrothermal tube
Face temperature greatly prolongs the service life of electric heater.
In order to solve the above-mentioned technical problem, the present invention includes container, and inlet and outlet, the appearance are provided on the container
It is axial inside device to be provided with support tube, eduction rod is provided in the support tube, it is radial between the support tube and container inner wall
Several supporting racks are provided with, support frame as described above upper edge container radial transmission line is wound with electrothermal tube, the both ends of the electrothermal tube and extraction
Stick connects.
Further, the one end is provided with process tube sheet, and the eduction rod is connect across process tube sheet with terminal box.
Preferably, the electric heating tube power on each supporting rack is sequentially reduced along import to export direction.
Further, it is provided with temperature controller on the electrothermal tube on each supporting rack.
The present invention is exchanged heat using the horizontal mode of plunderring, high turbulent condition, and the surface film thermal conductance of fluid and heating tube is just high, reduces
The surface temperature of electrothermal tube, extends the service life of electric heater.Independence may be used in each coil-shaped electric heater
Sensor control so that the maximum temperature of each coil-shaped heater as close possible to or it is equal, improve heater and stream
Mean temperature difference between body reduces the heat exchange area of electric heater, reduces equipment cost.Each coiling heater can be only
Vertical plate is around if intermediate certain damage, is unfolded coil pipe, is sliced off in breakage, transition spool piece is added to be connected, then again
Coiling, it is easy to maintenance.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the structural schematic diagram of supporting rack upper electrothermal tube.
Specific implementation mode
As depicted in figs. 1 and 2, the present invention includes container 7, and import 3 and outlet 5, the container are provided on the container 7
7 inside are axial to be provided with support tube 4, eduction rod 10 is provided in the support tube, eduction rod 10 is with electrothermal tube using identical
Material, difference are the stainless steel bars used among eduction rod.In order to facilitate the installation of support tube and eduction rod, the container 7
One end is provided with process tube sheet 2, and the eduction rod 10 is connect across process tube sheet 2 with terminal box 1.The support tube 4 and container 7
Several supporting racks 8 are radially provided between inner wall, 8 upper edge container radial transmission line of support frame as described above is wound with electrothermal tube 6, the electric heating
The both ends of pipe 6 are connect with eduction rod 10.It is consistent as possible in order to ensure the surface temperature of electrothermal tube, on each supporting rack 8
6 power of electrothermal tube is sequentially reduced along import 3 to 5 directions of outlet, and the low one end electric heating tube power of such heated material temperature is big,
The high one end electric heating tube power of heated material temperature is low, realizes that electrothermal tube temperature is uniform, provides electrothermal tube service life.
In addition, in order to further accurately control the temperature of electrothermal tube, temperature is provided on the electrothermal tube 6 on each supporting rack 8
Control device.
When manufacture, to ensure that there are the circulations of gap and guarantee fluid between electrothermal tube, before coiling electrothermal tube, per electricity
Tube surface coils the stainless steel wire of 1-2mm diameters in advance, it is ensured that has the passage gaps of 1-2mm between the electrothermal tube after coiling.
One aspect of the present invention due to using etc. Temperature Field Designs, reduce the heat exchange area of electric heater, save material and at
This.On the other hand more electric heating can be arranged since the technique of the size of U-shaped elbow limits unlike traditional electric heating tube
Pipe, can make electrothermal tube surface temperature lower, the heating particularly suitable for high-temperature gas.
