Description
Technical field
The invention belongs to environmental protection science and engineering, mechanical engineering and building engineering field, be a kind of water treating equipment, especially a kind of automatic feeding apparatus preparing pool for powdered activated charcoal.
Background technology
Development along with modern industry, agricultural and other industries, the drinking water source that the mankind depend on for existence pollutes serious day by day, the kind of contained pollutent and quantity are on the increase in the water, pollutant component also becomes increasingly complex, adopt conventional water treatment method can not meet the demands, must carry out advanced treatment.
At present, developed country and areas such as the U.S., Europe, Japan, the advanced treatment process in the water feeding system is comparatively ripe.Wherein, with gac as high-efficiency adsorbent, not only to dissolved organism in the water, has stronger adsorptive power as benzene-like compounds, phenolic compound, oil and petroleum products etc., and organism to being difficult to remove with biological process and other methods, as the organic compound of surfactant, weedicide, agricultural chemicals, synthetic detergent, synthetic dyestuff, aminated compounds and many synthetic, and colourity, foreign odor, peculiar smell all have removal effect preferably.In China, gac role in the drinking water deep treatment process comes into one's own just gradually and approves, to water treatment field wide application prospect is arranged in China based on the advanced treatment system of gac.
Under the current situation that can't reach drinking water source ground standard at source quality, the waterworks advanced treatment process that add Powdered Activated Carbon that adopt more.General 200～300 purpose Powdered Activated Carbons that adopt of this class technology are dropped into Powdered Activated Carbon in the water in proportion by specific equipment, stir the furnishing pulpous state, add through metering, adding equipment then.Usually be advisable at the middle part of flocculation basin in the position that adds of Powdered Activated Carbon, both avoided the absorption competition between charcoal slurry and the flco, guaranteed adsorption time again, and charcoal is attached to the flco surface, and the charcoal water sepn is effective.Dosage is decided on processing water quality, is generally 10～15mg/L.
But present domestic waterworks technology is comparatively outmoded, equipment is simple, traditional dosing method of Powdered Activated Carbon mostly is manually and adds (manual weighing's medicament) or simple and mechanical adding, slurrying promptly drops in the water because Powdered Activated Carbon is only through simple agitation, and there is very big defective in this technology when using:
1, be difficult to control dosage, add the operation out of true, it is low to add efficient.
2, simple agitation, slurrying is inhomogeneous, and can cause powdered carbon in place, dead angle deposition, and waste is serious.
3, stirring is abundant inadequately, and the medicament dispersiveness is bad, and easily conglomeration adds weak effect.
4, measure, add with pulping equipment simple and crude, poor sealing performance, dust from flying, work under bad environment.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of automatic feeding apparatus preparing pool for powdered activated charcoal, can carry out degree of depth mixing to Powdered Activated Carbon.
The present invention solves the problems of the technologies described above the technical scheme of being taked: a kind of automatic feeding apparatus preparing pool for powdered activated charcoal, preparing pool is located at the throwing device front end, be provided with whipping appts in the preparing pool, Powdered Activated Carbon stirs in drawing-in device is sent into preparing pool, make the charcoal slurry, delivering to coagulation basin by throwing device again adds, wherein, described preparing pool is the two-section type preparing pool, comprise first preparing pool and second preparing pool, the spout of drawing-in device is connected with first preparing pool, be provided with in first preparing pool and fall streaming impeller whipping appts, be provided with dividing plate and the water end (W.E.) face of the crossing UNICOM bottom dividing plate between first preparing pool and second preparing pool, be provided with paddle board formula whipping appts in second preparing pool, the discharge port of second preparing pool is connected with throwing device.
Two-section type preparing pool of the present invention more approaches plug flow reactor than traditional hybrid preparing pool of single lattice, and the residence time of all powder gac in the pond more helps forming even charcoal slurry near identical.Stirrer all is installed in first and second preparing pools to be stirred mixed solution, quicken mixing, wherein, first preparing pool adopts and falls streaming impeller whipping appts, be used for preliminary stirring, and the water-carrying section of mixed solution bottom dividing plate enters second preparing pool in the promotion pond, second preparing pool adopts paddle board formula whipping appts, increase stirring intensity, be used for degree of depth mixing.
On the basis of such scheme, the spout of described drawing-in device and first preparing pool are for being tightly connected, and the discharge port of second preparing pool and throwing device are for being tightly connected.Whole plant delivers into preparing pool from automatic feeding device, exports throwing device to charcoal slurry again and is and is tightly connected, and therefore allocates and add in the process can not produce dust, effectively improves Working environment.
On the basis of such scheme, the pool wall of described preparing pool is provided with turbulent baffle, turbulent baffle be arranged so that the Reynolds number of mixed solution increases greatly in the whipping process, under turbulent state, gac dry powder can mix more fully with water.
On the basis of such scheme, described first preparing pool and second preparing pool are square, and the inboard of four Chi Jiao is formed with and is 135 ° pond angle plane with the both sides pool wall.The pond angle plane can adopt and grout flat mode as cement sand and make, and so design has reduced the short stream district of preparing pool, avoids solid matter to deposit at Chi Jiaochu, increases operation rate.
On the basis of such scheme, the ratio of the length and width height of described first preparing pool and second preparing pool all is about 3:3:2.
On the basis of such scheme, above first preparing pool, ultrasonic level gage is installed, the liquidometer outside is provided with sleeve, and sleeve gos deep into preparing pool 0.45～0.55m downwards from the top.Ultrasonic level gage is installed in first preparing pool top can monitor liquid level automatically, control and coherent system operation, and the sheathed sleeve in the liquidometer outside is fully stirring under the violent situation of water fluctuation in addition, and the telescopic protection can guarantee that observed value is more accurate, steadily.
On the basis of such scheme, described second preparing pool top is equipped with the dedusting tube, is provided with the micropore filter cloth in the dedusting tube.Second preparing pool top is equipped with the dedusting tube, can prevent flying upward of material in the whipping process, avoids secondary pollution.
The invention has the beneficial effects as follows:
1, the present invention adopts the two-section type preparing pool, more help forming even charcoal slurry with respect to traditional hybrid preparing pool of single lattice, in the two-section type preparing pool,, improve the mixture homogeneity of Powdered Activated Carbon and water, reach degree of depth mixing earlier through tentatively stirring again through violent stirring;
2, the present invention is provided with turbulent baffle, and at the thorough mixing of turbulent state assurance gac and water, preparing pool pond dihedral becomes the plane, avoids deposition, increases operation rate;
3, drawing-in device to preparing pool, again to throwing device all by being tightly connected, guarantee that powder can not produce dust in the process of adding, effectively improve Working environment.
