Its advantages include high heating speed and efficiency, high safety and reliability, simple structure and convenient application. It is suitable for the electrically heated boiler as it can be made into high-power electrothermal converter.
Description
The present invention relates to a kind of electroheat technology, specifically a kind of electrical heating method and device that is used to add conducting liquids such as hot water.
We know, existing liquid electrical heating method mainly is to insert the heating that is connected on load circuit in the liquid or around the liquid, utilize the heating heating, heat conduction heating liquid, heating includes various resistance wires, Electric radiant Heating Film, semiconductor heater etc., in order to guarantee safety, need take the corresponding insulation measure, influenced electric conversion efficiency.At present, also have and utilize the electric conductivity that is heated liquid, adopt heaterless method, disclose a kind of self-heating electric heater unit as patent 91203177.8, it is submerged into electrode and is heated in the liquid, and the electrode outside is with cleat insulator and containment envelope.But live wire, zero line are difficult to identification, and security is still unreliable.Modern for extremely, also find the method and apparatus that utilizes three-phase electricity directly conducting liquid to be heated.
Purpose of the present 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.
For achieving the above object, 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, be with the clamshell of ground connection outward, they directly contact with being heated liquid, utilize the electric conductivity that is heated liquid, are heated liquid itself as heater element, the mixed form that star connects and triangle connects 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 electrode symmetries 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 symmetrically 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 suitable for being made into powerful electricity-heat converter, be specially adapted to be installed in the electrically heated boiler and use.
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.
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, be connected to electrode on three phase lines, the phase line electrode is immersed in and is heated in the liquid, be with the clamshell of a ground connection outward, clamshell also can connect the zero line of three-phase four-wire system, they directly contact with being heated liquid, are heated liquid itself as heater element, and the triangle that forms load between three electrodes connects, forming star between phase line electrode and clamshell connects, the liquid of energising heats liquid with the mixed form that star connects and triangle connects of threephase load, 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 heats with load star and 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 and adopts three, connect the phase line of three phase mains, electrode is distributed in the clamshell, and 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 symmetrically distributed in the cylinder clamshell, as shown in Figure 2.The conducting liquid as load is evenly distributed between electrode like this, 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, the triangle that conducting liquid has formed threephase load between three electrodes connects, the star that conducting liquid between electrode and clamshell forms threephase load connects, the present invention mixes the form that connects with three-phase conducting liquid itself is heated, it utilizes electric energy to pull the trigger conducting liquid, produce particle encounter and spontaneous heat to flowing down, reaches 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, and the efficient height is suitable for making powerful electric heater unit, is specially adapted to be installed in the electrically heated boiler use, and also is suitable for the heating of chemical industry medium solution.
