Abstract
The present invention relates to a polymerization hot water recycling system before polyamide slicing. The polymerization hot water recycling system comprises a fore-polymerization pipe (1), a melting kettle (3), a material preparing tank (4) and a storage tank (5), and is characterized in that a hot water outlet of the fore-polymerization pipe (1) is connected with an inlet of a heat exchanger (2), and an outlet of the heat exchanger (2) is respectively connected with jacket inlets of the melting kettle (3), the material preparing tank (4) and the storage tank (5). According to the present invention, fore-polymerization hot water is subjected to temperature adjustment through the heat exchanger so as to be used for thermal insulation of the melting kettle, the material preparing tank and the storage tank, the temperature is controllable, and steam consumption is reduced; and the system has characteristics of no environment pollution, comprehensive energy source utilization, and cost saving.
Description
Technical field
The present invention relates to a kind of polyamine section pre-polymerization Recovery of the hot water and utilize system, belong to chemical production equipment technical field.
Background technology
Polymeric amide section, is commonly called as polyamide fibre section, nylon chips.Because containing amido linkage (one C-NH mono-) in macromole, therefore be called polymeric amide.The polyamide fibre section cylindrical particle shape that is conventionally white in color, fusing point is 210-220 ℃, decomposition temperature is 300 ℃ of left and right.Dissolve in phenol and the hot vitriol oil, electrical insulation capability is superior, alkaline-resisting, good corrosion resistance.Polyamide fibre is the best fiber of wear resisting property in synthon.Because it has good wear resistance and corrosion resistance nature, become the main raw material of tire dipped type cord fabric, it is raw material that polyamide fibre adopts hexanolactam solid while producing, by melting, batching, pre-polymerization, polymerization, casting section, extraction, dry making.
In existing production technique, in melting, blending process, the insulation of its molten-bath, material-compound tank, hold tank is all the mode that adopts steam direct heating, and its energy consumption is larger, and the difficult control of temperature stability in insulating process; Hot water in pre-polymerization process directly discharges in addition, and because its temperature is higher, directly discharge meeting has a negative impact to environment, and energy consumption is larger.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide the polyamine section pre-polymerization Recovery of the hot water of a kind of comprehensive utilization of energy and environmental protection to utilize system.
The object of the present invention is achieved like this: a kind of polyamine section pre-polymerization Recovery of the hot water utilizes system, and it comprises pre-polymerization pipe, molten-bath, material-compound tank and hold tank; The hot water outlet of described pre-polymerization pipe is connected with the import of interchanger, and the outlet of described interchanger is connected with the chuck import of molten-bath, material-compound tank and hold tank respectively.
Compared with prior art, the invention has the beneficial effects as follows:
Polyamine section pre-polymerization Recovery of the hot water of the present invention utilizes system, by the hot water of pre-polymerization, by interchanger, regulates after temperature, and for the insulation of molten-bath, material-compound tank, hold tank, temperature is controlled, reduces the consumption of steam; This system neither can be to environment, and has reached the comprehensive utilization of the energy, has saved cost.
Accompanying drawing explanation
Fig. 1 is the structural representation that polyamine section pre-polymerization Recovery of the hot water of the present invention utilizes system.
Wherein:
1-pre-polymerization pipe;
2-interchanger;
3-molten-bath;
4-material-compound tank;
5-hold tank.
Embodiment
Referring to Fig. 1, a kind of polyamine section pre-polymerization Recovery of the hot water the present invention relates to utilizes system, and it comprises pre-polymerization pipe 1, interchanger 2, molten-bath 3, material-compound tank 4 and hold tank 5; The hot water outlet of pre-polymerization pipe 1 is connected with the import of interchanger 2, and the outlet of described interchanger 2 is connected with the chuck import of molten-bath 3, material-compound tank 4 and hold tank 5 respectively.
In the past polymerizing pipe 1 hot water out, after temperature is adjusted in interchanger heat exchange, enters respectively in the chuck of molten-bath 3, material-compound tank 4 and hold tank 5, and molten-bath 3, material-compound tank 4 and hold tank 5 are incubated, and its temperature stability is good, and easy to control.
Claims (1)
1. polyamine section pre-polymerization Recovery of the hot water utilizes a system, and it comprises pre-polymerization pipe (1), molten-bath (3), material-compound tank (4) and hold tank (5); It is characterized in that: the hot water outlet of described pre-polymerization pipe (1) is connected with the import of interchanger (2), the outlet of described interchanger (2) is connected with molten-bath (3), material-compound tank (4) and the chuck import of hold tank (5) respectively.
