Abstract
The utility model relates to a steam recycling device, in particular to a high-pressure steam recycling device of a PET (polyethylene terephthalate) crystallization system. The utility model is characterized in that the high-pressure steam recycling device further comprises a flash pot (6), a low-pressure steam pipeline (7) and a hot water pipeline (8); a steam trap (5) is connected with a water inlet of the flash pot (6) through a low-pressure steam pipeline (4); the low-pressure steam pipeline (7) is arranged at the top part of the flash pot (6); and the hot water pipeline (8) is arranged at the bottom of the flash pot (6). As the flash pot is additionally arranged in the high-pressure steam recycling device of the PET crystallization system, a low-pressure water-steam mixture is separated into low-pressure steam and hot water, therefore, the water resources are saved, and the production cost is reduced.
Description
(1) technical field
The utility model relates to a kind of steam reclamation set, relates in particular to a kind of high steam reclamation set of PET crystal system.
(2) background technology
Need to use the high steam of 22kg in the PET crystal system; yet in the use of high steam; can not directly be used by the superheated vapor mixture that produces behind heat exchanger and the steam trap, thereby usually these superheated vapor mixtures directly can be discharged.So not only waste water resource, also improved production cost.
(3) summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of conserve water resource, has reduced the high steam reclamation set of the PET crystal system of production cost.
The purpose of this utility model is achieved in that
A kind of high steam reclamation set of PET crystal system, comprise the high steam pipeline, pressure-reducing valve, heat exchanger, low-pressure water steam pipe road and steam trap, described high steam pipeline is provided with pressure-reducing valve, described high steam pipeline links to each other with the water inlet of heat exchanger, described low-pressure water steam pipe road links to each other with the delivery port of heat exchanger, described low-pressure water steam pipe road is provided with steam trap, it is characterized in that: it also comprises flash tank, low-pressure steam pipeline and hot water pipeline, described steam trap links to each other with the water inlet of flash tank by low-pressure water steam pipe road, described flash drum overhead is provided with the low-pressure steam pipeline, and described flash tank bottom is provided with hot water pipeline.
The beneficial effect that the utlity model has is:
The high steam reclamation set of this PET crystal system is by adding flash tank, the low pressure gas-vapor mix is separated into low-pressure steam and hot water, low-pressure steam can be transported to steam pipe system and recycle once more, hot water then can collect once more and utilize, so not only save water resource, also reduced production cost.
(4) description of drawings
Fig. 1 is the structural representation of the high steam reclamation set of the utility model PET crystal system.
Wherein: high steam pipeline 1, pressure-reducing valve 2, heat exchanger 3, low-pressure water steam pipe road 4, steam trap 5, flash tank 6, low-pressure steam pipeline 7, hot water pipeline 8.
(5) specific embodiment
As Fig. 1, the utility model relates to a kind of high steam reclamation set of PET crystal system, comprise high steam pipeline 1, pressure-reducing valve 2, heat exchanger 3, low-pressure water steam pipe road 4, steam trap 5, flash tank 6, low-pressure steam pipeline 7 and hot water pipeline 8, described high steam pipeline 1 is provided with pressure-reducing valve 2, described high steam pipeline 1 links to each other with the water inlet of heat exchanger 3, the delivery port of described heat exchanger 3 links to each other with steam trap 5 by low-pressure water steam pipe road 4, described steam trap 5 links to each other with the water inlet of flash tank by low-pressure water steam pipe road 4, described flash tank 6 tops are provided with low-pressure steam pipeline 7, be used for low-pressure steam is transported to steam pipe system, described flash tank 6 bottoms are provided with hot water pipeline 8, hot water is collected once more utilize.
This high steam reclamation set is transported to pressure-reducing valve 2 with high steam by high steam pipeline 1, make high steam reach the pressure of required 22kg by regulating pressure-reducing valve 2, be transported to subsequently in the heat exchanger 3 and lower the temperature, the low pressure steam that the cooling back forms is transported to 6 li of flash tanks by low-pressure water steam pipe road 4, flash tank 6 is separated into low-pressure steam and hot water with low pressure steam, low-pressure steam leads to recycling once more in the steam pipe system by the low-pressure steam pipeline 7 at flash tank 6 tops, and hot water then collects utilization once more by the hot water pipeline 8 of flash tank 6 bottoms.
Claims (1)
1. the high steam reclamation set of a PET crystal system, comprise high steam pipeline (1), pressure-reducing valve (2), heat exchanger (3), low-pressure water steam pipe road (4) and steam trap (5), described high steam pipeline (1) is provided with pressure-reducing valve (2), described high steam pipeline (1) links to each other with the water inlet of heat exchanger (3), described low-pressure water steam pipe road (4) links to each other with the delivery port of heat exchanger (3), described low-pressure water steam pipe road (4) is provided with steam trap (5), it is characterized in that: it also comprises flash tank (6), low-pressure steam pipeline (7) and hot water pipeline (8), described steam trap (5) links to each other with the water inlet of flash tank (6) by low-pressure water steam pipe road (4), described flash tank (6) top is provided with low-pressure steam pipeline (7), and described flash tank (6) bottom is provided with hot water pipeline (8).
