Abstract
The invention relates to the technical field of heat exchange, in particular to an electric heating device for a high-corrosivity and high-viscosity conducting medium. The electric heating device for the high-corrosivity and high-viscosity conducting medium comprises a pipe body 1, wherein the pipe body 1 is provided with an inlet end 2 and an outlet end 3; a plurality of electrode groups are arranged in the pipe body 1; and the power of each electrode group is successively reduced from the inlet end to the outlet end. The electric heating device for the high-corrosivity and high-viscosity conducting medium, which is disclosed by the invention, directly heats by the inside conducting medium, the temperature of the electrode is not too high, so that the electric heating device has a small possibility of scaling. Meanwhile, the fluid medium is heated from inside by self instead of heating the fluid medium from outside by electrode heating, and therefore the heat efficiency is high.
Description
Technical field
The present invention relates to technical field of heat exchange, especially a kind of highly corrosive high viscosity conducting medium electric heater unit.
Background technology
In heat exchanger technical field, often can run into and there is the occasion that highly corrosive high viscosity conductive medium need to heat; 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 problem to be solved in the present invention 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 present invention includes body, described body has entrance point and the port of export, is provided with some electrode groups in described body, and the power of each electrode group reduces to port of export direction successively from entrance point.
Preferably, described body is provided with the first electrode group being comprised of 9 electrodes near the position of entrance point, and the middle part of body is provided with the second electrode group being comprised of 6 electrodes, and the port of export of body is provided with the third electrode group being comprised 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 present invention 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 present invention 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 entrance point of the present invention 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 reached 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 present invention can be for highly corrosive high viscosity conducting medium is heated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes body 1, be provided with the liner 11 of being made by fiberglass or other insulation resistant materials in described body 1, 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 comprised of 9 identical electrodes of power near the position of entrance point 2, described electrode is made by 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 comprised of 6 electrodes, and the port of export of body 1 is provided with the third electrode group 6 being comprised 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 present invention 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, near the electrode temperature of the port of export 3, be unlikely to too high like this, thereby avoid fouling, also extended the useful life of product.
