Description
Technical field
The present invention relates to fine chemistry industry equipment technical field, a kind of crystallization apparatus refined for chlorophenol.
Background technology
Relating to the issues of purification of chlorophenol in chlorophenol production process, the purification for chlorophenol is typically all
In high tower, carry out high vacuum rectification, but chlorophenol is during rectification, need to bear the high temperature close to 200 DEG C, but
It is that chlorophenol is at high temperature susceptible to autohemagglutination, produces this highly toxic substance of two English；Not only make chlorophenol productivity, yield
Decline, and produce a large amount of distillation tail gas and residue, pollute environment.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, yield height, the crystallization refined for chlorophenol of environmental protection
Device.
The technical solution realizing the object of the invention is:
A kind of crystallization apparatus refined for chlorophenol, it is characterised in that include cylinder, the first end socket, the second end socket, fin

Improve the purity of chlorophenol, save the energy, also solve the problem polluting environment.
Below in conjunction with the accompanying drawings the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the crystallization apparatus that the present invention refines for chlorophenol.
Detailed description of the invention
Embodiment 1:
As it is shown in figure 1, a kind of crystallization apparatus refined for chlorophenol, including cylinder the 1, first end socket the 2, second end socket 3, wing
Sheet pipe 4 and fixed plate 5；One end of described cylinder 1 is provided with the first end socket 2, and the other end of cylinder 1 is provided with the second end socket 3, cylinder
Body 1 inner homogeneous be provided with some row's finned tubes 4, the two ends of finned tube 4 are provided with fixed plate 5；Described cylinder 1 uses sleeping
Formula cylinder, the top of cylinder 1 is disposed with charging aperture 6, thermometer socket 7, observation panel 8, drain 9, vacuum interface 10, true
Empty table socket 11, the bottom of cylinder 1 is provided with discharging opening 12；Described first end socket 2 be disposed with from top to bottom outlet 13,
First manhole 14, water inlet 15, the second end socket 3 is disposed with first service ports the 16, second manhole 17, second from top to bottom and ties up
Repair mouth 18；Described outlet 13 is connected with one end of finned tube 4, and water inlet 15 is connected with the other end of finned tube 4；Its
In, one end of described cylinder 1 is by bolt, screw thread or is welded to connect and is fixed with the first end socket 2, and the other end of cylinder 1 passes through spiral shell
Bolt, screw thread or be welded to connect and be fixed with the second end socket 3；The two ends of described finned tube 4 are separately fixed in the fixed plate 5 of correspondence,
Fixed plate 5 is fixedly connected with cylinder 1；Described cylinder 1 uses circular horizontal cylinder, and described first end socket 2 and the second end socket 3 are equal
Use ellipsoidal head；The bottom of described cylinder 1 is provided with bearing 19.
The operation principle of the crystallization apparatus that the present invention refines for chlorophenol:
Under vacuum, chlorophenol flows into cylinder 1 by charging aperture 6, opens cooling water pipe, makes cooling water pass through water inlet
15 flow in finned tube 4, and cooling water is flowed out by outlet 13, and cooling water makes chlorophenol be cooled to solid；Then close cold
But water, opens hot-water line, makes hot water pass through water inlet 15 and flows in finned tube 4, and hot water is flowed out by outlet 13；Hot water is with one
