Brief description of the drawings
The side schematic view when outer layer zone of heating is in open mode of the device of Fig. 1 present invention.
Embodiment
With reference to embodiment, the invention will be further described, but protection scope of the present invention is not limited to following realities
Apply example.
As shown in figure 1, the device of the present invention is divided into internal layer, intermediate layer and outer layer, internal layer is tubular reactor 1, and tubular type is anti-
The inside of device 1 is answered to be provided with thermocouple 2, thermocouple 2 is placed in catalyst and filler centre.Intermediate layer is exothermic layer, along pipe reaction
A screw type groove of circle circle is carved with the outer surface of device 1, is embedded in groove among the conduct of stainless steel tubule 3 of certain diameter
Layer, makes it closely be fit together with tubular reactor 1, and one end of stainless steel tubule 3 is entrance 4, and entrance 4 and heat conduction
5 yuan of the first temperature control list of liquid is connected, and the other end of stainless steel tube 3 is the outlet being connected with the first temperature control unit 5
61 and the drain 62 of gas in stainless steel tube 3 can be vented, the junction of its middle outlet 61 and drain 62 can be set
There is three-way valve.Outer layer is electric heating layer 7, and electric heating layer is stainless steel casing, and interior is resistive heater or heating Elema and guarantor
Adiabator, electric heating layer 7 are connected with for the second temperature control unit 8 of its heating, and electric heating layer 7 by electroheat pair 2
Temperature control.During catalyst reduction, the heat-conducting liquid in the stainless steel tube 3 in middle level is emptied, and needs stainless steel tube 3
Interior air emptying, so, will not because when gases are heated, they expand in heat-conducting liquid or stainless steel tube can not drain damage it is stainless
Steel pipe 3.Because stainless steel tube 3 is embedded in the surface of tubular reactor 1, and stainless steel tube 3 is the good conductor of heat in itself, so
Intermediate layer does not influence outer layer to the heat transfer of tubular reactor 1.Then, by outer layer the heated Tube reactor 1 of electric heating layer 7 to
Predetermined temperature, such as 500 DEG C.During low-temp reaction, the zone of heating of outer layer, which is in, stops heated condition, by heat-conducting liquid
Fluid therein is simultaneously continuously sent to stainless steel tube by the speed and temperature of the first temperature control unit 5 control conductive fluid
In 3, the flowing velocity of heat-conducting liquid and the fast cooling of temperature controlled tubular reactor 1 of thermosphere are taken with centre, so as to reach
To the purpose of temperature control.It can ensure that light ends fractionation hydrogenation and removing alkynes, alkene etc. are low from there through the combined use of heat supply and heat release
The normal operation of warm strong exothermal reaction.
As described above, embodiments of the invention are explained, as long as but essentially without this hair of disengaging
There can be various deformation in bright spirit and scope, this will be readily apparent to persons skilled in the art.Therefore, so
Variation be also integrally incorporated within protection scope of the present invention.
