Flocculation is exactly to the charge neutrality of fine particle in suspension and colloid and adsorption bridging by organic polymer coargulator, destroy the stability of these particles, it is made to contact with each other and agglomerated together, and then form larger floc sedimentation fast, can rapid subsidence, or realize under the effect of mechanical dehydration and being separated of water, the wastewater treatment needed after favourable.At present in various waste water treatment process, the use of flocculation agent is absolutely necessary assist measure.Flocculation agent is solid phase powder shape, and only having fully is dissolved in the water could play its throwing out well, and flocculant solution is apt to deteriorate, so need matching while using, uses fresh solution.
Current, all to add flocculation agent by manual work, the flocculation agent pulvis of manually toppling over directly enters in reaction tank, but for multiple flocculant concentration point, workload is larger, and pulvis does not pass through good dissolving, flocculation agent also can be gathered at the bottom of pond and become block sometimes, and its flocculating effect receives very large impact.In addition, often need the adjustment carrying out corresponding chemical feeding quantity and administration timing of drug according to the change of water quality in wastewater treatment process, can there is great error in manual operation, affect treatment effect.The operation of existing sewage disposal device is comparatively complicated, and operation is short of hands, and often occurs feeding intake not in time, pulvis scatters uneven phenomenon in the process added.These problems finally all can have influence on the result of water quality above, so, need automatic configuration and the adding technique of research and development flocculation agent badly.
In the prior art, flocculant solution preparation and the principle adding technology control the input of pulvis automatically mainly through a series of element such as electric, measuring apparatus, transfer roller, liquidometer and sensor, or within a certain period of time flocculation agent and water are hybridly prepared into solution and add.Series of problems is there is in this kind of technology in concrete use, such as: flocculating agent feeding device directly utilizes transfer roller that pulvis is sent into wastewater disposal basin, flocculation agent pulvis is added by the control metering of valve, because flocculation agent has certain viscosity, easily lump after making moist, not soluble, and the time one is long, valve will be blocked or adhere on a conveyor, cause equipment failure, affect the metering of pulvis.
Existing apparatus dissolution time and mixing speed in flocculant solution preparation process do not mate, and flocculation agent is higher for the requirement of stirring velocity.Stirring velocity is too fast, and the time is too short, can destroy the backbone of flocculation agent, loses throwing out; Stirring velocity is excessively slow, overlong time, and pulvis not easily fully dissolves, and also can lump or rotten, blocks follow-uply to add pipeline, causes equipment failure, therefore needs to determine suitable stirring velocity and dissolution time according to the character of flocculation agent.In addition, due to the special property of flocculation agent, the concentration requirement for flocculant solution is higher, if excessive concentration, viscosity is larger, and the liquidometer of some preparation facilities is in use easily bonded, and pipeline easily blocks, thus have impact on the preparation precision of flocculant solution.

Further, described flocculation agent pulvis is polypropylene phthalein amine flocculation agent, wherein, and polypropylene phthalein amine weight >=95%, granularity≤0.2mm.
According to the actual condition at wastewater treatment scene, the toss area of flocculation agent is multiple, and comparatively disperse, if directly flocculation agent is added in handled waste water, because the viscosity of flocculation agent is large, velocity of diffusion is low, can not be dispersed in waste water well, partial flocculation agent can be made not have throwing out, cause the waste of flocculation agent.Flocculation agent is solid phase powder simultaneously, and preservation requires higher, is not suitable for multiple spot at the scene and deposits and long distance delivery, must be translated into certain density flocculant solution by suitable method, then by adding pump delivery to each toss area.
For above-mentioned technical problem, the present invention devises a kind of automatization preparation facilities and method of flocculant solution, flocculation agent pulvis is first stored in the airtight filler bin of a positive pressuring drying, by the metering of spiral powder supplying mechanism, is delivered in an airtight measuring chute; Be malleation in measuring chute, have the pressurized air of pressure to drive flocculation agent pulvis to enter in mixing tank and mix with the uniform fluid flow sprayed; Then enter in the first dissolving vessel to stir and swelling reaction occurs, then enter in the second dissolving vessel to stir solubilizing reaction occurs, finally form flocculant solution, finally by transport pipe and add pump and be added to each toss area.
In the design of preparation method of the present invention and device:
(1) flocculation agent stores and metering
Flocculation agent pulvis is first stored in the filler bin of an opposing seal drying, be the pressurized air of 0.2 ~ 0.3MPa, clean dried by pipeline uninterrupted transfer pressure in storehouse, make filler bin internal gas pressure be greater than external atmosphere pressure, prevent extraneous moisture from entering, cause flocculation agent and become damp and rotten.
In spiral powder supplying mechanism, due to the gravity of flocculation agent pulvis and the frictional force effect with spiral powder supplying mechanism inwall, the flocculation agent pulvis being deposited in bottom does not rotate with spirochete, and only move forward under screw-blade promotes, arrive the suitable for reading of measuring chute, then because action of gravity is fallen in measuring chute.Whole course of conveying is a totally enclosed state, and operational throughput relies on spiral to control for the rotation time of powder equipment, so be very applicable to the conveying of flocculation agent.
Be the pressurized air of the clean dried of 0.2 ~ 0.3MPa by input pressure in measuring chute, pressurized air is not normal open, and its break-make is by the first solenoid control.After passing into pressurized air in measuring chute, storehouse internal pressure raises, and higher than barometric point.Due to differential pressure action, in measuring chute, pressurized gas enters in mixing tank with flocculation agent pulvis along pipeline, plays conveying effect.
(2) pre-mixing of flocculation agent and water
Polypropylene phthalein amine pulvis selected by flocculation agent pulvis of the present invention, when polypropylene phthalein amine and water dissolution, surrounded at once when each particle enters in water by water.Because it is swelling at once that polypropylene phthalein amine meets water, get together as several particle and fall into the water, the swelling rear particle in top layer not easily separates again, is unfavorable for follow-up dissolving.If directly thrown by pulvis and be added to the water stirring, pulvis energy uniform dissolution can not be guaranteed, so the present invention first carries out before dissolving dissolving after pre-mixing evenly in mixing tank, avoid pulvis and the caking phenomenon of water in dissolution process again.
Hydraulic pressure is that the water of 0.12 ~ 0.2MPa enters annular recesses by mixing tank water-in and flows into the tapered gaps that the very little and centripetal angle in cross section is 30 ~ 60 ° again, due to the sudden contraction of sectional area in this process, the flow velocity of current is by accelerating slowly, form a closed conical high-speed water jet in siphon district, jet-core region can produce certain entrainments flowing.Entered mixing tank by the flocculation agent pulvis that compressed air delivery is come, in siphon, stirring is entrainmented by water jet in district, then flows in mixing tank body, because sectional area becomes large, flow rate of water flow slows down, and spreads to surrounding, recover pipeline stream, powder particles is wrapped up by uniform fluid flow, enters the first dissolving vessel.
(3) flocculation agent dissolves
The preparation of flocculant solution need through two stages: swelling and dissolve.Because the size of flocculating agent molecule is more much bigger than the size of water molecules, both velocity of diffusion differ greatly.Water molecules is little and velocity of diffusion is very fast, and flocculating agent molecule chain is very long, intermolecular mutual entanglement, and reactive force is very large, not easily spreads.So flocculating agent molecule contacts the initial stage with water, as the pre-mixing phase, flocculation agent can not spread in water.But flocculating agent molecule chain has flexibility, molecular chain can produce hole due to thermal motion, and as being subject to the stirring etc. of external force, these holes are occupied by the molecule diffused out from water soon, and flocculating agent molecule volumetric expansion is swelling period.Along with swelling proceeds, water molecules constantly spreads to flocculation agent internal layer, the distance of flocculating agent molecule interchain is increased gradually, the interaction force of interchain reduces gradually, cause increasing chain to connect to loosen, flocculating agent molecule just can be diffused in water gradually, finally completes the process of dissolving.
Therefore, two stages that flocculation agent dissolves in water need different agitation conditions.At swelling period, need higher stirring intensity, make flocculating agent molecule rapid movement produce hole, allow water molecules occupy hole expand, reduce the reaction times, so, it is 300 ~ 400r/m that the present invention sets the first stirrer rotating speed in the first dissolving vessel, and churning time is 15 ~ 30min.
The present invention in order to prevent the backbone destroying flocculation agent in dissolution phase, makes flocculant solution lose throwing out, needs lower stirring intensity, allows the flocculating agent molecule of division be diffused into uniformly gradually in water, forms solution.Therefore, the rotating speed that the present invention sets the second stirrer in the second dissolving vessel is 100 ~ 150r/m, and churning time is 15 ~ 30min.
Preferably, the present invention's Vertical Uniform on the second dissolving vessel sidewall arranges 1 ~ 4 piece of flow-stopping plate, and effect is in whipping process, avoid eddy current to strengthen mixing effect, hinders flocculating agent molecule to be evenly diffused in water.
The present invention second dissolving vessel obtains flocculant solution of the present invention, then adds by adding transport pipe and adding pump after stirring and terminating.Within the scope of certain capacity, can multiple stage be set according to demand and adds pump, different process point be added simultaneously.
Beneficial effect of the present invention
