Abstract
The utility model relates to the technical field of the heat exchange, especially to an electric heating apparatus for high-corrosion and high-viscosity conducting medium. The electric heating apparatus comprises a tube body (1) having an inlet end (2) and an outlet end (3); a plurality of electrode groups are arranged in the tube body (1); and the power of each electrode group is successively reduced at a direction from the inlet end to the outlet end. According to the scheme, heating is realized directly by the internal conducting medium and the temperature of the electrode is not high, thereby preventing frequent scaling. Meanwhile, the electrode heating is realized by internal heating of the fluid medium itself instead of fluid medium heating from the outside, so that the thermal efficiency is high.
Description
Technical field
The utility model relates to technical field of heat exchange, especially a kind of highly corrosive high viscosity conducting medium electric heater unit.
Background technology
Often can run into and there is the occasion that highly corrosive high viscosity conductive medium need to heat in heat exchanger technical field; the such as heating such as water-coal-slurry, mud field; these media or corrosivity is high; or viscosity is high; but need heating; if with traditional heat exchanger or electric heater, body is easily corroded, useful life is not long.In addition, the velocity of medium that viscosity is high is very slow, heat on electrothermal tube is not easy to take away, the just easy overtemperature of electrothermal tube surface temperature, makes medium at body surface scale, affects the heat transfer of body, make body excess Temperature, also can shorten the useful life of firing equipment, and traditional heat exchangers or electric heater are bad to these full-bodied media entirety heating effects, implement heating very difficult.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of highly corrosive high viscosity conductive medium electric heater unit, and this heater has that fouling is few, long service life, feature that heating effect is good.
In order to solve the problems of the technologies described above, the utility model comprises body, described body has entrance point and the port of export, in described body, be provided with some electrode groups, the power of each electrode group reduces to port of export direction successively from entrance point, described body is provided with the first electrode group being made up of 9 electrodes near the position of entrance point, the middle part of body is provided with the second electrode group being made up of 6 electrodes, and the port of export of body is provided with the third electrode group being made up of 3 electrodes.
Further, described electrode wraps up by outside insulating case and body are fixed together.
Further, described body is steel pipe, is provided with frp lining in pipe.
The utility model is by the electrode at body diverse location configuration fair amount, form some electrode groups, under the effect of electrifying electrodes, conducting medium is energized heating, finally reaches the heated object of medium, because the inner portion of the utility model conducting medium directly generates heat, the temperature of electrode is not very high, is therefore not easy fouling, and heated by electrodes is not to heat to fluid media (medium) from outside simultaneously, but the inner self-heating of fluid media (medium), the heat efficiency is also high.
Because the medium temperature of the utility model entrance point position is when low, the number of electrodes of arranging is many, when port of export temperature is high, the number of electrodes of arranging is just few, so just reach the even of bulk temperature field, can not cause the position electrode excess Temperature near the port of export, extend the useful life of whole system yet.
In addition, frp lining is set in steel pipe, on the one hand makes casing insulation, also increased on the other hand the corrosion resistance of body, make the utility model can be for highly corrosive high viscosity conducting medium is heated.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises body 1, is provided with the liner 11 of being made up of fiberglass or other insulation resistant materials in described body 1, and described body 1 has entrance point 2 and the port of export 3, for inflow and the outflow of heated medium.
Described body 1 is provided with the first electrode group 4 being made up of 9 identical electrodes of power near the position of entrance point 2, described electrode is made up of corrosion resistant Langaloy, and every 3 electrodes are one group, and are connected with AC power.The middle part of body 1 is provided with the second electrode group 5 being made up of 6 electrodes, and the port of export of body 1 is provided with the third electrode group 6 being made up of 3 electrodes; Insulating case 7 and body 1 that above-mentioned all electrodes wrap up by outside are fixed together, and the heating end of described electrode stretches into body 1 inside.
Because the utility model reduces to the number of electrodes of the port of export 3 direction settings successively from entrance point 2, the lower fluid of temperature that just enters body 1 is carried out to powerful heating, the higher fluid of temperature near the port of export 3 is carried out to low power heating, be unlikely to too high near the electrode temperature of the port of export 3 like this, thereby avoid fouling, also extended the useful life of product.
