Description
（One）Technical field
The present invention relates to chloropropene production equipment field, more particularly to a kind of anticorrosion tubular heat exchanger.
（Two）Background technology
Shell-and-tube heat exchanger is a kind of heat exchanger of traditional structure, and market maintenance is very big.Built in commercially available shell-and-tube heat exchanger
Heat exchanger tube 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 exchanger tube
Tube side is long, and 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 is conducive to
The advantages of stress release, so U-shaped pipe heat exchanger is particularly suitable for the manufacture such as the big food of the working media temperature difference, heating and petrochemical industry
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 is produced, due to containing in chloropropene
There is a small amount of hydrochloric acid serious to equipment corrosion so that equipment loss is aggravated, parking checking number of times is high；Accordingly, it would be desirable to which a kind of improve is changed
The thermal efficiency, and corrosion resistant heat exchanger.
（Three）The content of the invention
There is provided a kind of anticorrosion tubular heat exchanger in order to make up the deficiencies in the prior art by the present invention.
The present invention is achieved through the following technical solutions：
A kind of anticorrosion tubular heat exchanger, including cylindrical shell, it is characterised in that：The shell one end is provided with the first end socket, separately
One end is 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；It is described to be somebody's turn to do
Feed liquor end pipe is welded to connect with the catch tray in the first end socket；The catch tray is connected by screw with heat exchange pipe mechanism；It is described
Heat exchange pipe mechanism includes being connected with some heat exchanger tubes between the tube sheet at two ends, tube sheet；Baffling gear is connected between the heat exchanger tube
Plate；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 pipe；
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 invention are as follows：The present invention avoids reactant from blocking heat exchanger in system knot carbon, improves heat exchange efficiency；
And prevent corrosion of the reactant to equipment；Heat exchange efficiency of the present invention is high, easy to use, installs simple.
（Four）Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the invention；
In figure, 1 housing, 2 first end sockets, 3 second end sockets, 4 feed liquor end pipes, 5 catch trays, 6 tube sheets, 7 heat exchanger tubes, 8 hydraulic barriers,
9 shell side inlet tubes, 10 shell-side outlet pipes, 11 first looped pipelines, 12 second looped pipelines, 13 air pumps, 14 outlet end pipes.
（Five）Embodiment
Accompanying drawing is a kind of specific embodiment of the invention.The embodiment includes cylindrical shell 1, and described one end of housing 1 is provided with first
End socket 2, the other end is provided with the second end socket 3；First seal head end 1 is provided with feed liquor end pipe 4, and the end of the second end socket 3 is provided with out
Liquid end pipe 14；The described feed liquor end pipe 4 is welded to connect with the catch tray 5 in the first end socket 2；The catch tray 5 by screw with
Heat exchange pipe mechanism is connected；The heat exchange pipe mechanism includes being connected with some heat exchanger tubes 7 between the tube sheet 6 at two ends, tube sheet 6；It is described
Hydraulic barrier 8 is connected between heat exchanger tube 7；The bottom of housing 1 is provided with shell side inlet tube 9, the top of housing 1 and shell side inlet tube
The 9 relative other ends are provided with shell-side outlet pipe 10；The top of housing 1 is provided with the first looped pipeline 11, the bottom of housing 1 and the first looped pipeline
The 11 relative other ends are provided with the second looped pipeline 12.The catch tray 5 is connected by screw with tube sheet 6；The catch tray 5 and tube sheet
