Description
Technical field
The present invention relates to industrial process electric-heating technology field, especially a kind of equal temperature fields electric heater.
Background technology
Existing industrial electric heating device is a kind of vessel shell of band inlet and outlet frequently with the structure of circulation heater
Boundling electrothermal tube structure is inserted into body.Fluid carries out heat exchange with cluster type electrothermal tube and achievees the purpose that fluid is heated.The structure
Major defect be：It is always seen from import to exporter, since electric heater is constant power density design from the beginning to the end,
The place of import causes the local electric heating tube wall temperature of import also low since medium temperature is relatively low, and the medium temperature of outlet is high,
The electric heating tube wall temperature in exit is also high.Especially high-temperature heating occasion is in use, the electric heating tube wall temperature in exit is wanted sometimes
Exceed or close to electrothermal tube highest heatproof, electrothermal tube can be caused often to damage, influence the service life of electric heater
Invention content
The technical problem to be solved in the present invention is to provide a kind of equal temperature fields electric heaters, can effectively reduce electrothermal tube
Maximum surface temperature keeps the surface temperature of electrothermal tube relatively uniform from import to export direction, and extend electric heater uses the longevity
Life.
In order to solve the above-mentioned technical problem, the present invention includes shell, is provided with electrothermal tube in the shell, on the shell
It is provided with inlet and liquid outlet, the end set of the close inlet of the shell has tube sheet, described electrothermal tube one end to pass through
Tube sheet is connect with anti-explosion terminal box, there are gap between the other end and housing bottom of the electrothermal tube, the electrothermal tube it is outer
A point journey plate is axially and symmetrically provided on surface, described point of journey plate is fixedly connected with inner walls, and the inner cavity of shell is separated into two
A cavity is also welded with several fins of metal material on the outer surface of the electrothermal tube.
Preferably, the fin is 10, is axially and symmetrically arranged in electric heating tube outer surface.
Further, the surface of the electrothermal tube is provided with temperature sensor, and shown temperature sensor is connect with temperature control device.
The present invention can improve the flow velocity of fluid, improve the coefficient of heat transfer of electric heater, effectively reduce entire electrothermal tube
The flow direction of fluid is formed round-trip both direction with time-division journey plate, so that the surface temperature of electrothermal tube is more uniformly distributed, carry by surface temperature
High heat exchange efficiency, and extend the service life of electric heater.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the cross-section diagram of electrothermal tube；
Fig. 3 is the schematic diagram in temperature field of the present invention.
Specific implementation mode
Embodiment cited by the present invention, is merely used to help understand the present invention, should not be construed as protecting model to the present invention
The restriction enclosed for those skilled in the art without departing from the inventive concept of the premise, can also be right
The present invention makes improvements and modifications, these improvement and modification are also fallen into the range of the claims in the present invention protection.
As depicted in figs. 1 and 2, the present invention includes shell 1, and electrothermal tube 2, the tube body of electrothermal tube 2 are provided in the shell 1
It is inside provided with heating wire, filled with the insulating materials such as ceramics or magnesia powder between heating wire and tube body.It is arranged on the shell 1
There are inlet 3 and liquid outlet 4, the shell 1 to there is tube sheet 5,2 one end of the electrothermal tube to pass through pipe close to the end set of inlet
Plate 5 is connect with anti-explosion terminal box 6, there are gap between 1 bottom of the other end and shell of the electrothermal tube 2, the electrothermal tube 2
A point journey plate 8 is axially and symmetrically provided on outer surface, described point of journey plate 8 is fixedly connected with 1 inner wall of shell, by the inner cavity of shell 1 point
Two cavitys are divided into, 10 fins 7 of metal material are also welded on the outer surface of the electrothermal tube 2, and are axially and symmetrically arranged
In 2 outer surface of electrothermal tube electrothermal tube is increased since the fin can increase the heat exchange area between fluid and electrothermal tube
The coefficient of heat transfer between fluid, and fin will occupy the certain space in cavity, can increase the flow velocity of fluid in shell,
The coefficient of heat transfer between electrothermal tube and fluid is further increased, to reduce the surface temperature of electrothermal tube.In order to control electricity
The surface of the maximum temperature of tube surface, the electrothermal tube 2 is provided with temperature sensor, shown temperature sensor and temperature control device
Connection.
As shown in figure 3, after medium is exchanged heat by the first shell side and electric heating tube, reach a certain temperature, then by dividing journey plate 8
It returns, the outlet temperature for reaching medium, the superposition of two tube side temperature so that the table of electrothermal tube 2 is reheated by the second shell side
Face temperature is uniform, such as uses thick-wall materials again, increases the conduction of heat, and 2 surface temperature of electrothermal tube evenly, also just extends electricity
The service life of heat pipe.
