Abstract
The invention provides an interpolating far infrared radiation electric heater comprising a jacket and a far infrared heat conductor, wherein the jacket is fixedly connected with a container. One end of the far infrared heat conductor is arranged in the jacket, and the other end is connected with a terminal box; the far infrared heat conductor is arranged on the peripheral surface at one end inside the jacket to be in clearance fit with the internal peripheral surface of the jacket. As the peripheral surface of the far infrared heat conductor is in clearance fit with the peripheral surface of the jacket, only the far infrared heat conductor is drawn out from the jacket for maintenance and replacement without integrally dismounting the heater when the heater is maintained and replaced after long time use, therefore, the heater has the advantages of convenient maintenance, thermal energy saving time and prolonged service life of the container.
Description
Technical field
The present invention relates to a kind of electric heater unit, a kind of especially interpolating far infrared electric heater unit belongs to the technical field of heater.
Background technology
The many production links of chemical industry all need to carry out chemical reaction under hot conditions, therefore, reactor be heated as crucial part.Traditional mode of heating has multiple, and as mode of heatings such as conduction oil, steam, tubular heat exchanger, naked light, inductance, but these modes all have shortcomings such as energy consumption height, temperature is wayward, potential safety hazard is big, environmental pollution is serious.Especially to large-scale reaction vessel because large-scale reaction vessel diameter is big, cylindrical shell is high again, rely on the outer heating of tradition, enough heat-transfer areas can not be arranged, therefore heat up slow and thermal losses bigger.
In order to solve these technical problems, interpolation type electric heater (abbreviation electric heating tube) has appearred, used electric heating tube in the prior art comprises overcoat, heating wire, described heating wire is arranged in the overcoat, be filled with the insulation bisque in the described overcoat, the electric heating tube of this structure, overcoat, heating wire and insulation bisque become whole, if can only integral replacing after occur damaging, therefore keep in repair cumbersome; And during maintenance, heater integral body to be disassembled in container, equipment must all be shut down, and material in the container (or thermophore) all to be bled off, so not only maintenance trouble, and owing to heating integral body has disassembled in container, the most of heat of material (or thermophore) in the container will leave, thereby cause thermal waste, influence production efficiency, strengthened operating cost; In addition, because the diameter of overcoat is little so the heat transfer sheet area is just little, the power that unit are is born is quite big, add the bad control of temperature, cause the carbonization of sleeve surface material easily, form the circumferential surface high temperature melting and puncture, thus the useful life (national regulation its useful life in 3000h) of having reduced heating tube.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of easy to maintenance, simple in structure, heat exchange area is big, quick heating, temperature control accurately, the little interpolating far infrared radiation electric heater of thermal losses, this heater can also be saved a large amount of heat energy of container, and long service life.
In order to solve the problems of the technologies described above, interpolating far infrared radiation electric heater of the present invention, comprise overcoat, the far infrared heat carrier of fixedlying connected with container, described far infrared heat carrier one end is arranged in the described overcoat, the other end connects terminal box, and described far infrared heat carrier is arranged on the outer peripheral face and the described outer sheath inner circumferential surface matched in clearance of an end in the described overcoat.
Above-mentioned interpolating far infrared radiation electric heater, wherein, described far infrared heat carrier comprises some heat conducting elements, described heat conducting element is integral along axially being fixedly connected sequentially.
Above-mentioned interpolating far infrared radiation electric heater, wherein, described shell is provided with the jockey that links to each other with container, described jockey comprises flange, bolt, described flange is fixedly connected on described shell periphery, described flange links to each other with container by bolt, described bolt comprises bolt body, tightens nut, descends clamp nut, anti-loosening cutting ferrule, described bolt body periphery is provided with at least one axial v-depression, described anti-loosening cutting ferrule inwall is provided with at least one double wedge that matches with described groove, during cooperation, described double wedge snaps in the described groove.Adopt the jockey of this structure that described electric heater unit and container are linked into an integrated entity, during work, can prevent that electric heater unit is loosening, avoid the material in the container to flow out, thereby improved the security performance of integral container.
Adopt the interpolating far infrared radiation electric heater of said structure, because the outer peripheral face and the described outer sheath inner circumferential surface matched in clearance of described far infrared heat carrier, long-time use the back to heater keep in repair, when changing, need not the heater integral demounting, only need extract the far infrared heat carrier out maintenance in the overcoat, change and get final product, so both make things convenient for maintenance, save heat energy and time again, and prolonged the useful life of container, reduced entreprise cost; Because described heat carrier is connected in sequence by some heat conducting elements, if when wherein its heat conducting element damages, a heat conducting element that only needs to damage is changed and is got final product, and need not whole heat carrier is changed together, therefore, has saved the use cost of enterprise again; In addition, because the present invention utilizes the far infrared heat carrier will to be transmitted fast by the heat that electric energy transforms as the insulation thermophore, simultaneously heat energy is changed into stronger far infrared spectral radiance, by heating apparatus container is heated again, therefore, this heating apparatus has the quickening of intensification, the little advantage of thermal losses; In addition, the present invention's matching relationship with far infrared heat carrier and overcoat improves and gets final product, and therefore, processes more convenient and simple in structure.
