Description
Technical field
The utility model is related to polyamide fibre production field, a kind of changing for slicing treatment in Pa-6 Polymerization produces is referred in particular to
Hot energy saver.
Background technology
Pa-6 Polymerization production main flow includes prepolymerization workshop section, final polymerization workshop section, pelletizing workshop section, extraction workshop section, drying
Workshop section, cooling workshop section and packing department.
It is sliced the moisture content in drying section needs the nitrogen of unsaturated humidity to take away slice, nitrogen, which becomes unsaturated humidity, to be needed
A large amount of steam are wanted to heat, a large amount of steam expend a large amount of electric energy and thermal energy.
Slice needs dry and cold nitrogen heat exchange to take away slice heat in cooling feed bin, and the hot nitrogen come out from cooling feed bin needs
Heat exchanger heat exchange becomes dry and cold nitrogen and forms nitrogen circulation；For heat exchanger using cooling water cooling, water cooling expends a large amount of electric energy, and
And largely carrying out cooling using cooling water can cause heat exchanger to corrode because of impurities in water, and heat exchanger service life is caused to subtract
It is short.
Invention content
The technical problems to be solved in the utility model, be to provide Pa-6 Polymerization slice production drying section and
A kind of heat exchange energy saver of slicing treatment of cooling workshop section.
The utility model is realized in this way：
A kind of heat exchange energy saver of slicing treatment, including drying tower, oxygen-removing tower, heater, cooling tower, heat exchanger and
Pre-heater, the drying tower connect the oxygen-removing tower and the heater, and the oxygen-removing tower connects the heater；It is described
Cooling tower connects the heat exchanger；The drying tower connects the cooling tower；The pre-heater connects the oxygen-removing tower, described
Heater, the cooling tower and the heat exchanger.
Preferably, further include supplemental heater, the supplemental heater connects the drying tower and oxygen-removing tower.
Preferably, further include control valve, the control valve controls the working condition of the pre-heater.
Preferably, further include wind turbine, the wind turbine accelerates flow velocity of the gas between each equipment.
The utility model has the advantage of：
1, it carries out thermal energy by the way that pre-heater connection drying section and cooling workshop section is arranged and shares, save in Liang Ge workshop sections
The thermal energy that the middle electric energy used and drying section use.
2, supplemental heater is set between drying tower and oxygen-removing tower, supplemental heater not only effectively shares adding for heater
Heat burden and the efficiency of heating surface for improving drying section nitrogen.
3, the working condition of pre-heater, drying section and cooling when pre-heater deactivates are controlled by the way that control valve is arranged
Workshop section also can normal operation, allow system to be more flexible.
4, reduce the use of cooling water because adding pre-heater, the cooling water into heat exchanger is reduced, to reduce
The corrosion that heat exchanger is subject to because of cooling water.
Description of the drawings
The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a kind of connection diagram of the heat exchange energy saver of slicing treatment of the utility model.
Symbol description is as follows：
Drying tower 1；Wind turbine 2；Supplemental heater 3；Oxygen-removing tower 4；Pre-heater 5；Heater 6；Cooling tower 7；Control valve 8；
Heat exchanger 9.
Specific implementation mode
Refering to Figure 1, a kind of heat exchange energy saver of slicing treatment, including drying tower 1, oxygen-removing tower 4, heater 6,
Cooling tower 7, heat exchanger 9 and pre-heater 5, the drying tower 1 connects the oxygen-removing tower 4 and the heater 6, described to remove
Oxygen column 4 connects the heater 6；The cooling tower 7 connects the heat exchanger 9；The drying tower 1 connects the cooling tower 7；Institute
It states pre-heater 5 and connects the oxygen-removing tower 4, the heater 6, the cooling tower 7 and the heat exchanger 9.
A kind of heat exchange energy saver of slicing treatment further includes supplemental heater 3, control valve 8 and wind turbine 2, the benefit
It fills heater 3 and connects the drying tower 1 and oxygen-removing tower 4, the control valve 8 controls the working condition of the pre-heater 5, institute
It states wind turbine 2 and accelerates flow velocity of the gas between each equipment.
A kind of specific implementation situation of the heat exchange energy saver of slicing treatment is as follows：
Slice drying in drying tower 1 requires heat to 125 DEG C or so, and temperature drops in cooling required in cooling tower 7
As low as 40 DEG C or so, pre-heater 5 connects the dry heat stage and cools the stage, the heat energy in the stage of cooling
In the dry heat stage.
Elder generation's closing control valve 8, first passes through in the heating period when a kind of heat exchange energy saver of slicing treatment uses pre-heater 5
Oxygen-removing tower 4, about 55 DEG C of nitrogen temperature at this time, after pre-heater 5 temperature about at 85 DEG C, finally again heated device 6 temperature
It is heated to 125 DEG C or so.Supplemental heater 3 is arranged in burden in order to reduce heater 6, and supplemental heater 3 improves nitrogen temperature.
A kind of heat exchange energy saver of slicing treatment comes out about 120 DEG C of temperature in cooling stage, nitrogen by cooling tower 7,
Temperature cools down about at 70 DEG C, then by heat exchanger 9 after temperature being shared to through pre-heater 5 again heating workshop section, eventually enters into
7 temperature of cooling tower is at 40 DEG C or so.
Although the foregoing describe specific embodiment of the present utility model, those familiar with the art answers
Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model
Fixed, those skilled in the art modification and variation equivalent made by the spirit according to the utility model all should
Cover in the scope of the claimed protection of the utility model.
