Abstract
The utility model provides a built-in type spiral fin jacket reaction vessel which comprises a shell pass, an inner jacket is arranged in the shell pass, a spiral fin which is contacted with the shell pass is helically wound on the inner jacket correspondingly to the position of the shell pass, and a heat transfer medium outlet opening and a heat transfer medium inlet opening are arranged at the upper part and the lower part of the shell pass. The utility model has the advantages that the reaction vessel is favorable for the heat exchange of the medium, the intensity is good, and the operation is safe.
Description
Technical field:
The utility model relates to a kind of reactor, particularly be a kind of built-in helical fin jacket reactor.
Background technology:
In Chemical Manufacture technology, tank reactor is the most general equipment, wherein needs the tank reactor of heat exchange, and forms such as chuck heat exchange, inner coil pipe heat exchange, semicanal heat exchange are arranged, and the chuck heat exchange is the most general.The jacket structured external chuck of being used always at present as shown in Figure 2, be splendid attire reaction medium a in the still, pass through hot medium medium b in the chuck, to reach heat exchange to medium a in the still, medium a is when carrying out chemical reaction in the still, need certain pressure, reaction conditions such as temperature, therefore when design and manufacturing jacket type heat exchange reactor, all according to the pressure of still internal reaction medium a, temperature, parameter conditions such as corrosion allowance design and make, its basic principle is: the pressure that is removed to bear reaction medium a by the shell side of still, temperature and corrosion, chuck removes to bear the pressure of hot medium medium b, temperature and corrosion, if the pressure of reaction medium a is during greater than the pressure of hot medium medium b (ordinary circumstance is all like this), the shell side Intensity Design of still is just greater than the Intensity Design of chuck, as adopts same material to make, so the thickness H of still shell journey
1Should be greater than the thickness H of chuck
2, the increase of thickness has just increased thermal resistance, and such structure is unfavorable for heat exchange very much, and overall heat-transfer coefficient generally all is less than or equal to 500kcol/M
2HC °.
The utility model content:
The purpose of this utility model is in order to overcome above deficiency, a kind of built-in helical fin jacket reactor that is beneficial to heat exchange to be provided.
The purpose of this utility model is achieved like this:
The built-in helical fin jacket reactor of the utility model comprises shell side, it is characterized in that being equipped with in the shell side interior chuck, on the interior chuck with the shell side opposite position on helically coiling the helical fin that is connected with shell side is arranged, hot medium media outlet, import are arranged in the shell side upper and lower part.
Referring to Fig. 1, hot medium medium b from the hot medium import of shell side bottom enter the chuck layer and along helical fin rise with chuck in reaction medium a carry out heat exchange, flow out from hot medium outlet at last.At the pressure of reaction medium a during greater than the pressure of hot medium medium b, the intensity of interior chuck is to design according to parameters such as the pressure of still internal reaction medium a, temperature, pressure in the still, temperature are born partly and outward by interior chuck, can also pass to shell side by the helical fin between shell side and the interior chuck gets on, the pressure that interior chuck bears is corresponding to be reduced, the thickness H of interior chuck
1Can be less than the thickness H of shell side
2, the thickness H between medium a and the hot medium medium b in the still like this
1Reduced with regard to corresponding, thermal resistance is also corresponding have been reduced, and helps heat exchange, overall heat-transfer coefficient can 〉=1000kcol/M
2HC °.On Intensity Design, reach same purpose of safety.
The utility model helps the medium heat exchange, and intensity is good, safety.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is existing external jacket reactor structural representation.
The specific embodiment:
Referring to Fig. 1, the bottom of shell side 1 and top are respectively equipped with hot medium medium import 2, outlet 3.Interior chuck 4 is positioned at shell side, twines at shell side and interior chuck inner spiral fin 5 spirals to have reached 0 gap with chuck on the chuck 4 and with the shell side comprehensive engagement in being welded on.Hot medium medium b from the import of hot medium medium enter along helical fin rise and with still in medium a carry out flowing out from outlet after the heat exchange.Stirring vane 6 in still is contained on the shaft 7, and motor 8 passes to power to make it on the shaft to rotate by transmission mechanism 9 and reaches the needed flowing velocity of medium a in the still.
Fig. 2 is existing external jacket reactor structural representation.
