Abstract
The utility model relates to a production line for the chemical fiber industry, in particular to a water-saving PET (Polyethylene Terephthalate) material-washing production line. The PET material-washing production line sequentially comprises a rinsing tank (1), a primary dehydrator (6), a washing tank (10), a secondary dehydrator (11), a primary clean water tank (2), a secondary clean water tank (9) and a sewage tank (7); the primary clean water tank (2) collects the wastewater of the rinsing tank (1) and the primary dehydrator (6) via a ditch (5), a return water pump (3) pumps the collected wastewater back into the rinsing tank (1), and a sewage pump (4) then pumps sewage into the sewage tank (7); the secondary clean water tank (9) collects the wastewater of the washing tank (10) and the secondary dehydrator (11) via the ditch (5), and a water pump (8) then pumps the collected wastewater back into the rinsing tank (1). Since the circulating water-saving system is added, clean water can be recycled, and thereby the production cost is reduced.
Description
Technical field
The utility model relates to a kind of assembly line equipment of chemical fibre industry, relates in particular to a kind of PET raw material washing flow line of water saving.
Background technology
The required PET raw material of terylene short-term industry production all is outsourcing, and is impure more with PVC, can't carry out direct production, and we must clean the raw material secondary processing of purchase for this reason, so that reach the requirement of production technique.At present raw material is handled mainly based on washing, needs a large amount of clear water, and clear water just once cleans and just drain later, consumes very greatly, and this not only makes the corresponding raising with unit cost of raw material processing, more is unfavorable for environmental protection and energy saving.
Therefore, how in the customer service PET raw material cleaning process flood tide consumption of clear water become a technical barrier.
The utility model content
The utility model provides a kind of PET raw material washing flow line of water saving, and it can make the clear water recycle, reduces clear water consumption, reduces production costs.In order to realize the foregoing invention purpose, the utility model has adopted following technique means:
A kind of PET raw material washing flow line of water saving comprises rinse tank, primary dewatering machine, rinse bath and second dehydration machine successively; Also comprise one-level clean water basin, secondary clean water basin and sewage lagoon; Described one-level clean water basin are drawn back rinse tank by the backwater water pump with the waste water of collecting by the waste water of irrigation canals and ditches collection rinse tank and primary dewatering machine, by the sewage water pump sewage are evacuated to sewage lagoon again; Described secondary clean water basin are drawn back the waste water of collecting to rinse tank by water pump by the waste water of irrigation canals and ditches collection rinse bath and second dehydration machine again.
Described one-level clean water basin are near the rinse tank setting; Described secondary clean water basin are near the rinse bath setting.
The beneficial effects of the utility model are: add a circulating water-saving system, the clear water circulation is recycled, reach default muddy degree and drain, made full use of water resources, the high production cost of avoiding unnecessary waste to cause.
Description of drawings
Fig. 1 is the structural representation of the PET raw material washing flow line of a kind of water saving of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the preferred implementation of the PET raw material washing flow line of a kind of water saving of the utility model is made detailed description:
As shown in Figure 1, existing P ET raw material washing flow line is earlier in rinse tank 1 rinsing, through sending into 6 dehydrations of primary dewatering machine after the two groove rinsings, after finishing, dehydration enters the intermediate treatment link, comprise steps such as boiling material, dealkalize water, send into rinse bath 10 again and clean, clean to finish through three-flute and send into 11 dehydrations of second dehydration machine, finish whole cleaning process.
The utility model has added a circulating water-saving system on the basis of original washing flow line, in position one-level clean water basin 2 are set near rinse tank 1 and primary dewatering machine 6, in position secondary clean water basin 9 are set near rinse bath 10 and second dehydration machine 11, two clean water basin all are circumscribed with irrigation canals and ditches 5, in order to collect waste water, one-level clean water basin 2 are collected the waste water of rinse tank 1 and primary dewatering machine 6, and secondary clean water basin 9 are collected the waste water of rinse bath 10 and second dehydration machine 11; Secondary clean water basin 9 are provided with water pump 8, in order to the waste water of collecting is drawn back to rinse tank 1, one-level clean water basin 2 are provided with backwater water pump 3 and sewage water pump 4, backwater water pump 3 is drawn back to rinse tank 1 in order to the waste water that continues to utilize that will collect, and sewage water pump 4 is evacuated to sewage lagoon 7 with unavailable waste water.
In the time of the work of this streamline, mainly reach the purpose of water saving by the circulation of two aspects: the first is drawn back the rinse tank 1 of one-level clean water basin 2 collections and the waste water of primary dewatering machine 6 to rinse tank 1 by backwater water pump 3 again, recycle, after the cycle index of setting, utilize sewage water pump 4 that sewage is evacuated to sewage lagoon 7, the sewage that sewage lagoon 7 is collected is delivered to the waste water treatment plant again; It two is that the rinse bath 10 secondary clean water basin 9 collected by water pump 8 and the waste water of second dehydration machine 11 are drawn back to rinse tank 1 again, because it is very clean by the intermediate treatment link to deliver to the raw material of rinse bath 10, so the backwater clean level of rinse bath 10 and second dehydration machine 11 is quite high, can directly draw back to rinse tank 1 recycling.Water circulation use by this two aspect has made full use of water resources, has reduced production cost when having avoided the wasting of resources.
Claims (2)
1. the PET raw material washing flow line of a water saving comprises rinse tank (1), primary dewatering machine (6), rinse bath (10) and second dehydration machine (11) successively; It is characterized in that: also comprise one-level clean water basin (2), secondary clean water basin (9) and sewage lagoon (7); Described one-level clean water basin (2) are drawn back rinse tank (1) by backwater water pump (3) with the waste water of collecting by the waste water of irrigation canals and ditches (5) collection rinse tank (1) and primary dewatering machine (6), by sewage water pump (4) sewage are evacuated to sewage lagoon (7) again; Described secondary clean water basin (9) are drawn back the waste water of collecting to rinse tank (1) by water pump (8) by the waste water of irrigation canals and ditches (5) collection rinse bath (10) and second dehydration machine (11) again.
