Summary of the invention
Technical problem to be solved by this invention is exactly in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of efficiency of heating surface height, security performance is good, structure is reasonable, simple installation, electrical heating method easy for operation and device.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of electrical heating method, it is characterized in that it uses three-phase (380V/220V) power supply, be connected to electrode on the phase line, electrode is immersed in and is heated in the liquid, and the periphery is provided with the clamshell of ground connection, electrode and clamshell be heated liquid and directly contact, utilization is heated the electric conductivity of liquid, be heated liquid itself as heater element, the mixing that star connects and triangle the connects connection form with threephase load heats liquid.
A kind of electric heater unit of realizing above-mentioned electrical heating method, it includes electrode, insulation utmost point seat, clamshell, it is characterized in that three electrodes that connect the three phase mains phase line are distributed in the clamshell of ground connection, around the clamshell and bottom is provided with louvre, and the electrode upper end is fixed on the clamshell by insulation utmost point seat.The present invention is proof load symmetry and three-phase electricity balance, and the phase line electrode is tubular, and clamshell is cylindrical, and three phase line electrodes are evenly distributed in the cylinder clamshell.
The present invention is power supply with the three-phase electricity, its firing rate is fast, efficient is high, safe and reliable, and it is simple in structure, easy for operation, long service life, be a kind of desirable conducting liquid electrical heating method and device, be applicable to and make powerful electricity-heat converter, be specially adapted to be installed in the electrically heated boiler and use.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a distribution of electrodes schematic diagram of the present invention.
The specific embodiment
A kind of electrical heating method of the present invention, it utilizes the electric conductivity of conducting liquid (as water), use three-phase (380V/220V) power supply, article three, be connected to electrode on the phase line, electrode is immersed in and is heated in the liquid, be with the clamshell of ground connection outward, clamshell also can connect the zero line of three-phase four-wire system, electrode and clamshell etc. be heated liquid and directly contact, be heated liquid itself as heater element, the triangle that forms load between three electrodes connects, forming star between the electrode of phase line and clamshell connects, this heater realizes that the mixed form that star connects and triangle connects of threephase load heats liquid, and liquid is heat loss through convection from the clamshell louvre, reaches the purpose of heating whole liquid.Liquid beyond clamshell ground connection of the present invention or the connecting to neutral line, the clamshell thermal treatment zone is not charged, thereby has guaranteed safety.Three-phase electricity realizes load star and the heating of leg-of-mutton mixed form, efficiency of heating surface height, and electric conversion efficiency reaches more than 90%.
Realize the device of electrical heating method of the present invention, as shown in Figure 1, it includes electrode 1, insulation utmost point seat 2, clamshell 3.Electrode adopts three, connects the phase line of three phase mains respectively, and electrode is distributed in the clamshell; Clamshell 3 is provided with some louvres, ground connection or connect the zero line of three-phase electricity during use.Electrode 1 of the present invention is fixed on the clamshell 3 by insulation utmost point seat 2.Clamshell 3 electromotive forces are zero, and it plays shielding action on the one hand, plays zero wire electrode on the other hand.In order to guarantee the firm of electrode position, also can be provided with an electrode supporting plate 4 in the clamshell, be arranged with three electrode holes on it, the electrode lower end is therefrom passed, and plays fixation.
That electrode of the present invention can be selected for use is tubular, plate shape, clavate, and in order to guarantee the three-phase electricity balance, electrode preferably is tubular, also is processed with louvre on the wall, and 3 cylindrical, the band ends of clamshell, electrode is evenly distributed in the cylinder clamshell, as shown in Figure 2.Electrode is evenly distributed in the conducting liquid as load, and the load symmetry has guaranteed three-phase electricity balance and safe in utilization.
Electric heater unit electrode of the present invention and clamshell adopt said structure, and the triangle that conducting liquid has formed threephase load between three electrodes connects, and electrode connects with the star that conducting liquid between clamshell forms threephase load.The present invention has realized that the mixing that star connects and triangle connects of three-phase electricity connects form, conducting liquid itself is heated, utilize electric field energy to bombard, pull the trigger the particle vibration such as molecule, ion, collision of conducting liquid and produce heat, to flowing down, reach heating purposes at liquid medium.This device clamshell electromotive force is zero, and is not charged in the solution beyond the clamshell, the security performance height.
This electric heater unit is simple in structure, and volume is little, and firing rate is fast, security performance is strong, and the efficient height is applicable to and makes powerful electric heater unit, particularly suitable is installed in the electrically heated boiler, also is suitable for the heating of nearly quinaldine acid basicity medium solution in chemical industry and other industry.
