Description
Technical field
The utility model belongs to a kind of papermaking wastewater treatment device.
Background technology
At present, the slurrying during paper waste is mainly produced from paper industry and copy two production processes of paper.Slurrying is the fiber separation in plant material out, makes slurry, then through bleaching, this process can produce a large amount of paper wastes; Copy paper and be slurry dilute, moulding, squeezing, oven dry, make paper, this process also easily produces paper waste.Paper waste is processed and should be focused on the cycling use of water rate that improves, and reduces water consumption and wastewater discharge, also should try to explore various reliable, economical and can take full advantage of the method for wastewater treatment of useful resources in waste water simultaneously.Fibering solid matter in the recyclable plain boiled water of flotation waste water facture, but primary water reuse; Sodium hydroxid in burning waste water treatment process recyclable Heisui River, sodium sulphite, sodium sulfate and with other sodium salts of organism combination.In and waste water treatment process regulate waste water ph; Coagulating sedimentation or flotation process can be removed suspended solids in waste water; Chemical precipitation method can be decoloured; Biological treatment can be removed BOD, and is more effective to kraft paper waste water; It is comparatively successful that wet oxidation process is processed the sulfite paper pulp waste water.In addition, the paper waste treatment processs such as the reverse osmosis of employing, ultra-filtration, electrodialysis are also arranged both at home and abroad.Paper waste is the larger trade effluent of a kind of intractability, generally by physico-chemical process+biochemistry, pollution substance is wherein degraded.Because the contained pollutent of waste water itself is very complicated, after treatment, though water outlet can reach emission standard substantially, but with the require apart from each other of waste water recycling to water quality, adopt the treatment process such as traditional sand filtration, activated carbon filtration, multi-medium filtering to realize the waste water recycling processing, just to a certain degree reduce the water outlet concentration of suspension, solubility pollutent such as COD, ammonia nitrogen and salt in sewage are graded and can't further remove, if reuse can directly have influence on the paper effect.The general reuse water of paper industry often is only limited to the production technique not high to water quality requirement such as the slagging-off, pulp washing, rinsing of production process, and these workshop section's waters have certain requirement to indexs such as COD, turbidity, iron, existing filtering technique can not satisfy the water quality requirement of these workshop sections, and traditional cascade filtration technique has the shortcomings such as long flow path, floor space is large, product water water quality is unstable.Must adopt advanced middle water reuse treatment process, on the basis of original sewage qualified discharge, further reduce iron in water, COD concentration, can directly as reuse water, be used for the workshop sections not high to water quality requirement such as slagging-off, pulp washing, rinsing on the one hand; Middle water after processing on the other hand can be directly by reverse osmosis or ion-exchange desalination, exempt that in reverse osmosis process, multistage security personnel filter and ultrafiltration technology, has reduced the pre-treatment expense, prolongation RO film work-ing life.At present, the paper waste processing there is and takies the place greatly, length consuming time, the low deficiency that waits of work efficiency.
Through Chinese publication retrieval, find 142 of relevant patents of invention, 44 of utility model patents are not found the scheme identical with present patent application.
Summary of the invention
The utility model purpose is, for the deficiencies in the prior art, proposes a kind of waste-water vortex treatment unit.
Waste-water vortex treatment unit of the present utility model, the right cylinder that comprises the hollow in top, the tank body (6) that the vertebral body that one of bottom communicates with right cylinder consists of is main body, tank body (6) upper end is provided with water inlet pipe (2), rising pipe (4), the lower end is provided with underflow opening (7), it is characterized in that: be provided with the cone basket sieve (5) that is connected with drive unit (3) in tank body (6).On described cone basket sieve (5), filtering net (12) is installed; The outlet (9) of the tank inner segment of preferred water inlet pipe (2) is by the lower semisection that is located in tank body (6) right cylinder, and preferably the direction of the outlet (9) of the tank inner segment of its water inlet pipe (2) is set to along tank body (6) inwall tangent to periphery direction; The outlet (9) of the tank inner segment of preferred its water inlet pipe (2) is connected with nozzle (10).
Waste-water vortex treatment unit of the present utility model, principle of work: waste water is by water inlet pipe (2), with along tank body (6) inwall tangent to periphery direction, enter in tank body (6), rotatablely move along tank body (6) inwall circumference under its waste water mobilization, cone basket sieve (5) is driven and the rotation of waste-water vortex equidirectional by drive unit (3), and waste-water vortex is accelerated, and forms current vortex phenomenon.It is due to the restriction that is subject to wall of the outer-rotor, forces liquid to do top-down rotatablely moving, and usually this motion is called outer eddy flow or decline swirling motion.Solid particulate in outer eddy flow is subject to centrifugal action, if density is greater than the density (this is most applications) of surrounding liquid, its suffered centrifugal force is just larger, in case this power is greater than the liquid resistance that produces because of motion, solid particulate will overcome this resistance and move to the wall direction, separates with suspension, arrives near the particle of wall and is subject to continuous liquid-driving, move downward along wall, arriving to assemble near underflow opening (7) becomes multiviscosisty greatly
Suspension, discharge from underflow opening.Liquid after isolation of purified (certainly wherein also have some tiny particles) rotation continues motion downwards, and after entering conical section, because the internal diameter of wet cyclone dwindles gradually, liquid in rotation speed is accelerated.When producing vortex motion due to liquid, radially pressure distribution is uneven, and is more less near the axis place and level off to zero when arriving axis, becomes low pressure area and even is to cause liquid to trend towards axis direction and move in the vacuum zone.Simultaneously, because wet cyclone underflow opening (7) dwindles greatly, liquid can't be discharged from underflow opening (7) rapidly, and after eddy flow process filter screen (12), enter rising pipe (4), owing to being in low pressure area, a part of liquid is moved to it, thereby form rotatablely moving of making progress, also discharge from rising pipe (4) through filter screen (12).When the foreign material that part fiber or density are less rise together with water, owing to filtering net (12) being installed with its interception on cone basket sieve (5), again brought in swirling motion by eddy flow, finally also discharge from underflow opening (7).
The present invention's beneficial effect compared with prior art: be that a machine has simultaneously the water cyclonic separation and mutually promotes with filtration and play and improve the dual-use function separate and to filter, and simple structure; Materials consumption is few, and cost is low, and the throughput of unit volume is larger, accounts for area little; Consuming time few, the work efficiency advantages of higher, the waste water reclamation cyclic utilization rate can reach more than 95%.
