For the treatment of the system of paper-making pulping waste water
The utility model relates to a kind of system for the treatment of paper-making pulping waste water.
Paper industry (mainly slurrying) wastewater discharge is large, seriously polluted, and ecological impact is large, is puzzlement countries in the world paper industry and the hot issue of environmental protection organization and the emphasis of research for many years always.For reducing paper-making industrial waste water to the harm of environment, paper industry must set up corresponding Waste Water Treatment.
But, the existing Waste Water Treatment being applied to paper-making pulping aspect, all there is complex structure, defect that floor space is large, particularly its reactor, most employing be the structure of fixing stirring rake, laterally can only stir, can not longitudinally stir, thus the stirring efficiency of waste water and chemical feedstocks is lower, have impact on the treatment effect of system to waste water.
Utility model content
The purpose of this utility model is to provide a kind of system for the treatment of paper-making pulping waste water, mainly solves papermaking wastewater treatment system and there is complex structure, floor space is large, water treatment effect is not good problem.
To achieve these goals, the technical solution adopted in the utility model is as follows:
For the treatment of the system of paper-making pulping waste water, comprise pond, the water pump that water-in is communicated with this pond by pipeline, the hydraulic ejector be communicated with this pump outlet, by the reactor tank body that air suction pipe is connected with this hydraulic ejector, by the header tank that return water pipe is connected with hydraulic ejector bottom, be fixed on the power set on reactor tank body, be connected with this power set and extend into the stir shaft of reactor tank interior, the longitudinal stirring rake be threaded with this stir shaft, one end is fixed on reactor tank body upper inside wall, the other end runs through longitudinal stirring rake and end is provided with the fixed link of block, be connected to stir shaft end, for preventing the fixing block piece of longitudinal stirring rake landing, and the horizontal stirring rake be arranged on this fixing block piece, described reactor tank body is respectively equipped with water inlet pipe, discharge nozzle.
Further, described water pump is vacuum pump.
Again further, described power set is drive-motor.
Further, described reactor tank base is provided with bracing frame.
Compared with prior art, the utility model has following beneficial effect:
The utility model structure is simple, floor space is little, it is by arranging hydraulic ejector, longitudinal stirring rake, horizontal stirring rake, when hydraulic ejector makes current converge in same focus, because jet water course speed is higher, and longitudinal stirring rake longitudinally stirs up and down, horizontal stirring rake laterally stirs, reactor tank interior is fully reacted, and form negative pressure, produce vacuum, then waste water just can be made to accelerate evaporation concentration dehydration, enriched material is discharged, the water of evaporation then enters return water pipe by hydraulic ejector bottom, and flow to header tank, then get back to workshop to continue to recycle.And, the utility model is by the improvement to stirring rake structure, make it while can laterally stirring, also can carry out longitudinal stirring, thus not only significantly improve efficiency and the effect of stirring, and the treatment effect to paper-making pulping waste water can be improved with the combination of hydraulic ejector, and decrease the power consumption of whole system, significantly reduce cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, the component name that Reference numeral is corresponding is called:
1-pond, 2-water pump, 3-hydraulic ejector, 4-air suction pipe, 5-reactor tank body, 6-water inlet pipe, 7-discharge nozzle, 8-power set, 9-stir shaft, the longitudinal stirring rake of 10-, 11-fixed link, 12-block, 13-fixes block piece, the horizontal stirring rake of 14-, 15-header tank, 16-bracing frame.
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
As shown in Figure 1, the utility model is mainly for the treatment of the waste water produced during paper-making pulping, it comprises pond 1, the water pump 2 that water-in is communicated with this pond 1 by pipeline, the hydraulic ejector 3 be communicated with this pump outlet, by the reactor tank body 5 that air suction pipe 4 is connected with this hydraulic ejector 3, by the header tank 15 that return water pipe is connected with hydraulic ejector 3 bottom, be fixed on the power set 8 on reactor tank body, be connected with this power set and extend into the stir shaft 9 of reactor tank body 5 inside, the longitudinal stirring rake 10 be threaded with this stir shaft 9, one end is fixed on reactor tank body 5 upper inside wall, the other end runs through longitudinal stirring rake and end is provided with the fixed link 11 of block 12, be connected to stir shaft 9 end, for preventing the fixing block piece 13 of longitudinal stirring rake landing, and the horizontal stirring rake 14 be arranged on this fixing block piece 13, described reactor tank body 5 is respectively equipped with water inlet pipe 6, discharge nozzle 7.In the present embodiment, described water pump 2 is preferably vacuum pump, and described power set 8 is drive-motor.
In addition, bracing frame 16 is also provided with bottom described reactor tank body 5.
When the utility model uses, paper-making pulping waste water and chemical feedstocks are added in reactor tank body 5 simultaneously, start drive-motor, stir shaft 9 is made to drive longitudinal stirring rake 10 and horizontal stirring rake 14 to stir waste water respectively, at this wherein, because longitudinal stirring rake 10 is threaded with stir shaft 9, and the spacing of fixed link 11 is had, therefore, longitudinal stirring rake 10 can move up and down along with the rotation of stir shaft 9; Horizontal stirring rake 14 then rotates along with the rotation of stir shaft 9 under the drive of fixing block piece 13, thus makes waste water and chemical feedstocks fully react.Then, open water pump 2, it is made to be pumped in hydraulic ejector 3 by the water in pond 1, hydraulic ejector 3 is utilized to make current converge in same focus, because jet water course speed is higher, add moving up and down of longitudinal stirring rake 10, and the rotation of horizontal stirring rake 14, thus the water sprayed into can form negative pressure in reactor tank body 5 inside, make in reactor tank body 5 and produce high vacuum, the waste water in it is made to accelerate dehydration by evaporation, and the enriched material after dehydration just can be discharged by discharge nozzle 7, and as required it is recycled, and the vaporize water taken away by hydraulic ejector flow to header tank by the diffuser tube of hydraulic ejector bottom through pipe fitting gets back to workshop and continue to recycle.So namely complete the wastewater treatment to paper-making pulping.
