The heat exchanger tube put mainly has straight tube and U-shaped two kinds of structural shapes, on the premise of same size, because U heat exchange is than straight heat exchange
The tube side length of pipe, built-in medium heat exchange is more abundant, and heat exchange efficiency is higher, is on the other hand that the U-shaped bending structure of heat exchanger tube has
The advantages that beneficial to stress release, so U-shaped pipe heat exchanger is particularly suitable for the big food of the working media temperature difference, heating and petrochemical industry etc.
Manufacturing industry heat-exchange system is supporting.But U-shaped pipe heat exchanger easily forms shape
Into the stifled phenomenon of stream, it is necessary to frequently parking maintenance；And the heat exchanger when chloropropene produces, due to chloropropene
In it is serious to equipment corrosion containing a small amount of hydrochloric acid so that equipment loss aggravates, and parking checking number is high；Therefore, it is necessary to which one kind carries
High heat exchange efficiency, and corrosion resistant heat exchanger.
（Three）Utility model content
The utility model is in order to make up the deficiencies in the prior art, there is provided a kind of anticorrosion tubular heat exchanger.
The utility model is achieved by the following technical solution：
A kind of anticorrosion tubular heat exchanger, including cylindrical shell, it is characterised in that：The shell one end is provided with the first envelope
Head, the other end are provided with the second end socket；The first end socket end is provided with feed liquor end pipe, and the second end socket end is provided with outlet end pipe；
The described feed liquor end pipe is welded to connect with the catch tray in the first end socket；The catch tray is connected by screw and heat exchange pipe mechanism
Connect；The heat exchange pipe mechanism includes the tube sheet at both ends, and some heat exchanger tubes are connected between tube sheet；It is connected between the heat exchanger tube
Hydraulic barrier；The lower housing portion is provided with shell side inlet tube, and the housing upper other end relative with shell side inlet tube is provided with shell side
Outlet；The housing upper is provided with the first looped pipeline, and the lower housing portion other end relative with the first looped pipeline is provided with the second looped pipeline.
The catch tray is connected by screw with tube sheet；Sealing gasket is provided between the catch tray and tube sheet.
The hydraulic barrier includes upper hydraulic barrier and lower hydraulic barrier；The upper hydraulic barrier connects with top heat exchanger tube
Connect；The lower hydraulic barrier is connected with bottom heat exchanger tube；The upper hydraulic barrier and lower hydraulic barrier are staggered.
First looped pipeline connects air pump by pipeline.The heat exchanger tube is polypropylene material.
Mixed with graphite in the heat exchanger tube, graphite accounts for polyacrylic 15%-20%.
The beneficial effects of the utility model are：The utility model avoids reactant from blocking heat exchanger in system knot carbon, improves
Heat exchange efficiency；And prevent corrosion of the reactant to equipment；The utility model heat exchange efficiency is high, easy to use, and installation is simple.
