Abstract

The utility model provides a multifunctional fixed bed reactor, which can improve the stability of reactor and comprises a cylinder; the upper end and the lower end of the cylinder are provided with an end enclosure; a tube plate is arranged between the cylinder and the end enclosure; a heat exchange tube is arranged on the tube plate; the lower part of the cylinder is provided with a heat carrierinlet; the upper part of the cylinder is provided with a heat carrier outlet. The Multifunctional fixed bed reactor is characterized in that the cylinder is provided with an expansion joint.

Description

Multi-functional fixed bed reactors
(1) technical field
The utility model relates to a kind of fixed bed reactors, is specially multi-functional fixed bed reactors.
(2) background technology
Calandria type fixed bed reactor generally is applicable to the reaction that fuel factor is bigger, it comprises cylindrical shell, inner barrel is provided with the heat exchanger tube that axially is parallel to each other, the cylindrical shell bottom is provided with the thermophore import, cylindrical shell top is provided with the thermophore outlet, and wherein heat exchanger tube is to be welded on the tube sheet, because the temperature difference is big in the reactor, the heat exchanger tube inequality of being heated, its expand with heat and contract with cold cause easily the mouth of pipe automatically weldering come off; In addition, the thermophore import generally all is vertically to be installed on the barrel wall, because the heat carrier temperature is very high, heat exchanger tube will bear very big pressure, influences whole reactor stability.
(3) summary of the invention
At the problems referred to above, the utility model provides multi-functional fixed bed reactors, and it can improve the stability of reactor.
Its technical scheme is such: it comprises cylindrical shell, described cylindrical shell upper/lower terminal is provided with end socket, be provided with tube sheet between described cylindrical shell and the end socket, on the described tube sheet heat exchanger tube is installed, the cylindrical shell bottom is provided with the thermophore import, cylindrical shell top is provided with the thermophore outlet, and it is characterized in that: described cylindrical shell is provided with expansion joint.
It is further characterized in that: described thermophore importer enters to the tangential direction along barrel wall; Also be provided with distributor on the end socket of described top.
Calandria type fixed bed reactor of the present utility model, its cylindrical shell is provided with expansion joint, increased the scope that heat exchanger tube expands with heat and contract with cold greatly because of the temperature difference, make performance stability be improved, in addition, the thermophore import adopts tangential direction to enter in the cylindrical shell, has reduced the thermal shock of exchange heat pipe, has further improved performance stability; And the distributor that is provided with on the end socket of top can make reaction material be evenly distributed on the one hand, has further improved the stability of reactor on the other hand.
(4) description of drawings
The structural representation that Fig. 1 looks for the utility model master.
(5) specific embodiment
See Fig. 1, the utility model comprises cylindrical shell 1, cylindrical shell 1 upper/lower terminal is provided with end socket 2 and 3, be provided with tube sheet 4 between cylindrical shell 1 and the end socket 2,3, heat exchanger tube 5 is installed on the tube sheet 4, cylindrical shell 1 bottom is provided with thermophore import 6, and cylindrical shell 1 top is provided with thermophore outlet 7, and cylindrical shell 1 is provided with expansion joint 8.Thermophore import 6 directions enter along the tangential direction of barrel wall; Also be provided with distributor 9 on 2 end sockets of top.Among Fig. 1,10 is combi inlet port, and 11 is mixed gas outlet, and 12 is the ear seat, and 13 is deflection plate, and 14 is distance sink tube.
