Efficient sedimentation tank
Efficient sedimentation tank is collection coagulation, chemical method except hardness, sludge circulation, inclined plate (inclined tube) separation and sludge condensation etc.
It is a variety of theoretical in one, the mud-water separation developed by rational waterpower and structure design and sludge condensation functions it is heavy
Shallow lake technique.The special reaction zone of efficient sedimentation tank and settling section design make it be to substitute traditional coagulative precipitation tank, machinery clarification
The novel depositing technology in pond etc..Its operation principle is based on the following aspects:
The flocculation tank of integration in protonotion;
Pulling flow type reaction tank is to the transmission at a slow speed between sedimentation basin;
The external recirculation system of sludge;
Tube settling mechanism.
Efficient sedimentation tank technological principle is specific as follows:
High-rate sedimentation pool process completes body refuse, medicament, raw water in hybrid reaction area by the promotion immixture of blender
Quick aggregation, then through impeller be promoted to plug-flow reaction zone carry out flocculation reaction at a slow speed, to form larger floccule body.
Entire reaction zone (mixing and plug-flow reaction zone) can get a large amount of high density homogeneous alumen ustum, and this highdensity alumen ustum allows to sink
The settling velocity in shallow lake area is larger, without influencing effluent quality.
1) coagulation area
Lime, soda ash and coagulant dosage in raw water, under the action of flash mixer with raw water in suspended matter it is quick
Mixing, the negative electrical charge by neutralizing particle surface make particle " de- steady ", form small flco subsequently into flocculation basin.
2) flocculation zone
Flocculant promotes small flco by the flco of absorption, electrically neutralization and mutual bridging action formation bigger, slowly
The effect of fast blender had not only enable medicament and flco be sufficiently mixed but also will not destroy established big flocculating body.
3) tube settling district
Water outlet flows upward to upper-part centralized pool after entering settling zone after flocculation, and particle and flco are deposited on the surface of inclined tube
And it glides under the effect of gravity.60 ° of higher upflow velocity and inclined tube, which tilt, can form a continuous process scraped certainly, make wadding
Body will not be accumulated on inclined tube.
The sludge of precipitation slips down to bottom of pond along inclined tube, and sludge is concentrated in bottom of pond.Grizzly bar on mud scraper can improve
Sludge condensation effect, the mud scraper rotated at a slow speed continuously blow into sludge center collection mud pit.Thickened sludge is set according to certain
Determine program or controlled by mud level meter to reach the sludge concentration of an optimization, is then discontinuously discharged to Treatment of Sludge system
System.
Efficient sedimentation tank has the characteristics that:
A. highly dense and uniform alumen ustum;
B. the flocculation reaction optimized;
C. high settling rate, is precipitated using efficient inclined plate (inclined tube), and raw water is divided evenly in entire pond body;
D. the structure of highly compact, special flocculation reactor design, plug-flow transition is used from flocculation zone to settling zone;
E. perfect reflux control, settling zone to flocculation zone is by the way of controllable external sludge backflow and adds high score
Sub- flocculant, make flocculation formed even floccule and it is intensive, have very high sinking speed, therefore efficient sedimentation tank have processing
Construction investment and floor space is greatly saved in advantage efficient, unit area water yield is big;
F. sludge dewatering is not necessarily to pre-concentration, and sedimentation basin lower part is arranged larger enrichment region, makes the solid content of discharge sludge more
Height, without other sludge condensation facilities, is conducive to follow-up Treatment of Sludge up to 3%~5%;
G. remarkable effluent quality;
H. stable, load resistance and changes in flow rate impact.
Sludge treating system includes:Sludge-tank, sludge-tank blender, chamber-type press filter, sewage sludge feed pump, flush water pump etc.
It constitutes.The sludge that efficient sedimentation tank generates makes the water in sludge be discharged by filter cloth, to reach sludge by the extruding of sheet frame
The purpose of dehydration.Spoil disposal initially enters in sludge-tank, and being lifted into filter press through sewage sludge feed pump carries out press dewatering, sludge-tank
Inside it is provided with machine mixer.By the stirring action of impeller, the effects that reaching mixing, plug-flow, prevent sludge settling.
The filtrate of filter press is expelled to regulating reservoir, after dehydration mud cake by transported on trucks to factory outside.Plate and frame filter press operation one
The section time need to be rinsed filter cloth, and one to biweekly filter cloth is rinsed using high-pressure plunger pump, is removed and is blocked up on filter cloth
The sludge of plug.
Crystal system, main heat exchanger containing forced circulation, flash tank, dewaterer, the several units of condenser.By taking TVR as an example,
Crystallizer uses the steam drive of 0.4MPa (g), can adjust crystallization by adjusting the mode of crystallizer heat exchanger shell pass pressure
The evaporation efficiency of device, therefore this operating method provides larger adjusting elasticity.
In view of hardness is higher in raw water, salinity is complicated in water, therefore crystallizer uses forced circulation form.The pressure
Circulation crystallization device can be run under conditions of a variety of not syncrystallizations generate.And falling liquid film system can be in the condition for having crystal of calcium sulfate
Lower operation (since crystal of calcium sulfate kinetic reaction rate is relatively slow), but if there is other crystalline deposits, then system is very
It is fragile.
The design of forced circulation is very reliable, needs less cleaning than falling liquid film design.Forced circulation design for viscosity
The related problem such as increasing to suspended matter has good resistance, as water distribution unevenness, heat exchanger tube cannot be soaked fully and low be changed
Heating rate etc..
Applied to extra hydrochloric acid and by-product acid is removed during synthesizing polyvinyl chloride, the hydrogen chloride in hydrochloric acid is carried out most
Bigization desorption, and spent acid is not generated, hydrochloric acid depth desorption effect is good.The hydrochloric acid of concentration about 30%, with acid pump pressurization after with chlorination
After the one jet mixer mixing of the calcium chloride solution of calcium circulating pump conveying, into desorption tower, mixed solution is from stripping tower top
Portion enters, by the way that efficient mass transfer process occurs when filler and internals during flowing downward under gravity.Meanwhile it is molten
Liquid is constantly heated by thermal siphon Natural Circulation reboiler, and in this way, steam, which is distilled, isolates and flow up in this behaviour
During work, hydrogen chloride gas is stripped from hydrochloric acid and calcium chloride mixed solution and is discharged from tower top.Calcium chloride solution is conduct
Azeotropic breaks object, and the partial pressure of water vapour is inhibited for the partial pressure of hydrogen chloride gas.
The hydrogen chloride saturated acid vapour being stripped off obtains dry hydrogen chloride and send after B-grade condensation and demisting remove the acid mist of deentrainment
VCM is synthesized.And bottom of tower obtains dilute calcium chloride solution containing micro HCL, into calcium chloride flash concentration part.It is introduced into chlorine
Change calcium concentration tower, which is connected with thermal siphon natural-circulation evaporator.In this stage, excessive water is flashed
It is evaporated, it is collected into wastewater trough after water vapour fully condense by evaporated vapor condenser, returns to water scrubber, made
It is used for supplement absorbent (clear water).Calcium chloride solution after concentration recycles pumped back desorption tower with calcium chloride and recycles.
