Description

The pure water filtration recovery system of one way of life paper using
Technical field
The utility model relates to mthod of white water from paper making recovery technology field, particularly relates to the pure water filtration recovery system of one way of life paper using.
Background technology
In recent years, country gets up tighter to environmental requirement, sewage drainage standard is more and more higher, and paper industry is the use of China
Water rich and influential family, and due to paper mill discharge waste water be difficult to recycling, serious impact is caused on environment, in order to meet wastewater discharge standard, enterprise only has and constantly improves production technology, the wastewater processing technology that transformation falls behind, reduce water consumption ability, by industrial water recycle after treatment.
In existing paper making process, what screen cloth water under high pressure, PEO dilution water etc. used is clear water, and cause workshop water consumption higher, plain boiled water discharge capacity is comparatively large, waste resource; On the other hand, plain boiled water adopts the frame sieve that shakes to carry out filtration treatment, and its white water consistency is still higher, cannot recycle.
Summary of the invention
The purpose of this utility model is to avoid weak point of the prior art and provides that a kind of white water recovery rate is high, the pure water filtration recovery system of the paper for daily use of energy-conserving and environment-protective.
The purpose of this utility model is achieved through the following technical solutions:
The pure water filtration recovery system of one way of life paper using is provided, comprise many disk filters, also comprise turbid back flow water pump, pure tank, plain boiled water sieves and super pure pond, the water inlet of described plain boiled water sieves is communicated with described pure tank, the delivery port of described plain boiled water sieves is communicated with described super pure pond, and the super pure water that described super pure pond is collected is recycled to paper machine room by low-pressure pump;
Described many disk filters comprise the first filtrate (liquid and the second filtrate (liquid, and described first filtrate (liquid is communicated with described turbid back flow water pump, and described second filtrate (liquid is communicated with described pure tank.
Preferably, described turbid back flow water pump is connected with described pure tank.
Preferably, described turbid back flow water pump and described pure tank be connected by same face wall and the height of described same face wall lower than the height of other metopes.
Preferably, described plain boiled water sieves is pressurized screen.
Preferably, described many disk filters comprise spray equipment, and the delivery port in described super pure pond is communicated with by the sparge pipe of supply-water pump with described spray equipment.
Preferably, the pipeline between described super pure pond and described low-pressure pump is provided with flow control valve.
the beneficial effects of the utility model:
The pure water filtration recovery system of one way of life paper using of the present utility model, compared with prior art, filtered and recycled process is carried out when the plain boiled water produced from paper machine room wet end is delivered to many disk filters, the filtrate of filtered and recycled is delivered to respectively turbid back flow water pump and pure tank, then the pipeline between pure tank and super pure pond increases plain boiled water sieves, again filtered and recycled process is carried out to the pure water in pure tank, its white water consistency is made to be reduced to below 10ppm, super pure Water Sproading after filtration is to paper machine room, can be used for screen cloth spray, the places such as PEO dilution, thus greatly reduce the rinse dosage in workshop, make production more clean, environmental protection, achieve the recycled for multiple times of plain boiled water.
