Abstract
Disclosed is a cylindrical whirlpool type electric heater, which heats up the system on-line flowing medium and enables the flowing medium to achieve mixed flow in the cylinder and no dead zone so as to reach a balanced temperature without sudden coldness or hotness. The electric heater is composed of a temperature control regulator, a heater cylinder body, a safety valve, an electric heater, a heater cylinder cap, an exhaust valve, an exhaust valve core and a pressure-detection joint. The heater cylinder is composed of support legs, a bottom seal head, a cylinder body, a heater mounting plate, an upper flange, a lower flange, an upper diversion chamber, a lower diversion chamber and a chamber partition board through welding. The fluid medium enters into the opening of the lower flange and runs through the lower diversion chamber and then is ejected from 12 pipes which form a 45-degree angle with the horizontal direction on the chamber partition board; finally the fluid medium flows out of the opening of the upper flange through the upper diversion chamber. The chamber partition board can separate the cold area of the medium from the heating area of the medium, and can change the laminar flow of the fluid medium into mixed whirlpool type.
Description
Affiliated technical field:
The utility model is a kind of the online flow media of system to be heated, and makes flow media realize mixed flow in cylindrical shell and do not have the dead band, reaches temperature equalization, does not have the tubular spiral-flow type electric heater of sometimes hot and sometimes cold phenomenon.
Background technology:
At present, tubular electric heater structure is to pick up survey element, connecting terminal block etc. by cylindrical shell, heating, temperature to assemble by machinery.The cold medium to be heated of being come by pumping directly enters heating region from the next flange port of cylindrical shell, being full of cylinder lumen under the effect of pressure and flow velocity very soon discharges incessantly from the upper flange port of tube, flow media around the heat transferred that heating is produced under the energising situation reaches the purpose to the medium heating.; because general cylinder lumen is smooth garden cylindrical cavity; the medium of continuous-flow must cause flow dead at cylinder lumen; medium is the laminar flow shape and flows in cylindrical shell, and its flow velocity slows down, to making the heating element heater area carbon; therefore heat transfer efficiency is low; the big deficiency that consumes energy, heated medium temperature is unbalanced, and sometimes hot and sometimes cold MEDIA FLOW group phenomenon is arranged.
Summary of the invention:
Cause the medium of continuous-flow to cause flow dead in order to overcome existing tubular electric heater at cylinder lumen, medium is the laminar flow shape and flows in cylindrical shell, its flow velocity slows down, to making the heating element heater area carbon, therefore heat transfer efficiency is low, the big deficiency that consumes energy, heated medium temperature is unbalanced, and sometimes hot and sometimes cold MEDIA FLOW group is arranged.The utility model provides a kind of tubular spiral-flow type electric heater, it is by safety valve, packing ring 27, electric heater, electric heater pad, screw M12, adds long threaded rod, steel pipe, nut, plug screw, packing ring, steam discharge valve body, steam discharge spool, pressure measuring tie-in, screw M3, thermoregulator support and heater cylindrical shell and link to each other, temperature control damper is installed on the thermoregulator support, and heater cover and heater cylindrical shell are fastening.The heater cylindrical shell is to be welded on the cylindrical shell successively by heater installing plate, lower flange, upper flange, last diversion cavity, separate space plate, following diversion cavity, the separate space plate is located at the lower flange place, cylindrical shell is divided into two chambeies up and down, the cold-zone and the thermal treatment zone, the separate space plate is by 12 jet pipes from the horizontal by miter angle in 12 eyelet weldings that make progress in endless belt week of annular bottom plate, the end casing of several vertical aperture of then burn-oning in the middle of it.Fluid media (medium) enters from the lower flange mouth, after following diversion cavity, 12 ejections from the horizontal by the hole of the jet pipe of miter angle and end casing from the separate space plate, electric heater heating by the thermal treatment zone, again through last diversion cavity, flows out from the upper flange mouth.Not only this tubular spiral-flow type electric heater makes flow media realize mixed flow in cylindrical shell and does not have the dead band, reaches temperature equalization, does not have sometimes hot and sometimes cold phenomenon, and has certain flow velocity by the medium of heating element heater, make the no carbon distribution in heating element heater surface picture now, coefficient of overall heat transmission height, little benefit consumes energy.
The technical scheme that its technical problem that solves the utility model adopts is: tubular spiral-flow type heater is made up of temperature control damper, heater cylindrical shell, safety valve, electric heater, heater cover, exhaust valve, exhaust plug, pressure measuring tie-in etc.; The heater cylindrical shell is welded by footing, bottom (head), cylindrical shell, heater installing plate, upper flange, lower flange, last diversion cavity, following diversion cavity, separate space plate etc.; The separate space plate can separate the cold-zone of medium and the thermal treatment zone, can become mixed flow eddy flow shape to fluid media (medium) from laminar flow again, and it is to be welded by base plate, jet pipe, end casing.Fluid media (medium) enters from the lower flange mouth, after following diversion cavity, 12 ejections from the horizontal by the hole of the jet pipe of miter angle and end casing from the separate space plate, electric heater heating by the thermal treatment zone, again through last diversion cavity, flows out from the upper flange mouth.
This practicality adds novel beneficial effect from being: not only this tubular spiral-flow type electric heater makes flow media realize mixed flow in cylindrical shell and does not have the dead band, reach temperature equalization, there is not sometimes hot and sometimes cold phenomenon, and has certain flow velocity by the medium of heating element heater, the no carbon distribution in heating element heater surface is now looked like, coefficient of overall heat transmission height, little benefit consumes energy.
