When the utility model reactor used, catalyst was seated in space between heat exchanger tube, was that saturation boiling water is as heat transferring medium absorption reaction warm in the heat exchanger tube.Reaction gas gets into the reactor internal reaction from the air inlet on housing top; The reaction back goes out reactor from the gas outlet, bottom; Saturation boiling water gets into the import chuck and is distributed in each heat exchanger tube from the heat transferring medium import, and the reaction gas countercurrent flow that flows between pipe, is pooled to the outlet chuck after the heat exchange again; And export out reactor from heat transferring medium, remove the drum separate vapour.When being provided with the center set of heat exchange tubes in the housing; Most of saturation boiling water gets into each heat exchanger tube from the heat transferring medium import; With the reaction gas countercurrent flow; Fraction saturation boiling water gets into the center set of heat exchange tubes from the center set of heat exchange tubes water inlet of lower housing portion, lower tube box, countercurrent flow after upper tube box, center set of heat exchange tubes delivery port go out reactor and remove drum.
When the utility model reactor is used, can external drum and circulating pump, the heat transferring medium that goes out reactor is sent to the drum separate vapour, again Natural Circulation or get into reactor to the heat transferring medium import through the circulating pump forced circulation.
The utility model device has the following advantages:
1. adopt the stringing mode of special compactness, can arrange more heat exchanger tube, strengthen the heat energy power of moving.
2. the heat exchanger tube bending two ends is welded on the housing; Can solve the flexible problem of heat exchanger tube that thermal stress causes, its structural reliability is increased, be convenient to simultaneously make and maintenance; Only need open external jacket during maintenance gets final product; The center set of heat exchange tubes also can be extracted maintenance separately out, extracts out in the post-reactor and can advance the people, and bigger operating space is arranged.
3. cancel large tubesheet and big flange, reduced investment.
4. be applicable to the newly-built and transformation project of reactor, flexible.
