Detailed Description

The invention will be further described with reference to the accompanying drawings:

as shown in figures 1-2, pentachloropropane graphite reboiler, including upper cover 8, barrel 5 and apron 1 down, set up graphite heat transfer piece 4 in the barrel 5, the distribution has the material passageway 14 of vertical setting in the graphite heat transfer piece 4, and the horizontal vapor passageway 13 that sets up, the vertical water conservancy diversion passageway 15 that sets up in graphite heat transfer piece 4 middle part, graphite heat transfer piece 4 is run through at both ends about the water conservancy diversion passageway 15, the periphery of water conservancy diversion passageway 15 sets up annular channel 16, the inner of vapor passageway 13 communicates annular channel 16 respectively. The graphite heat exchange block 4 is arranged to be a cylinder corresponding to the cylinder 5, the material channels 14 are uniformly arranged in the radial direction of the graphite heat exchange block 4, and the water vapor channels 13 are uniformly arranged in the axial direction of the graphite heat exchange block 4. The upper end enclosure 8 is connected with the barrel 5 through a compression bolt 7, the compression bolt 7 is uniformly distributed along the circumference of the upper end enclosure 8, a spring compression device 9 is arranged on the compression bolt 7, and the spring compression device 9 is positioned on the upper portion of the compression bolt 7. The pressing flange 2 is arranged between the lower cover plate 1 and the cylinder body 5, and the lower cover plate 1, the pressing flange 2 and the cylinder body 5 are connected through the pressing bolt 7. The lateral part of the cylinder 5 is respectively provided with a steam inlet 10, a drain opening 6, an ear seat 11, a condensed water outlet 12 and a drain opening 3, the steam inlet 10 and the condensed water outlet 12 are respectively connected with a steam channel 13 at the top and a steam channel 13 at the bottom, the drain opening 6 is positioned at the upper part of the cylinder 5, and the drain opening 3 is positioned at the lower part of the cylinder 5.

In fig. 1, the up-down arrow indicates the direction of material inlet and outlet, corrosive chemical materials enter the graphite heat exchange block 4 from the material inlet of the equipment, and the water vapor inlet 10 conveys water vapor to enter the graphite heat exchange block 4 through a transverse pore passage for heat transfer, so as to form a heat exchange body; after the materials are heated and boiled, the materials flow through the longitudinal hole of the graphite heat exchange block 4 and are discharged from the material outlet. The water vapor flows through the transverse channels and finally is discharged from the condensed water outlet 12 of the flow channel. The pentachloropropane is easy to generate coking phenomenon in the rectification reboiling process, and the small aperture is easy to generate blocking phenomenon, so that the equipment can not be used due to blocking.
