Abstract
The utility model relates to a sludge chemical conditioning device and discloses a powdery conditioning agent emulsion preparation and addition device. The powdery conditioning emulsion preparation and addition device comprises a preparation tank, wherein a stirrer is arranged in the preparation tank, and a stirring motor, a speed reducer and a powdery conditioning agent inlet are arranged on the stirrer; the upper half part of the side wall of the preparation tank is provided with a water inlet pipeline and an emulsion discharge pipeline, and the upper end surface of the preparation tank is also provided with a powdery conditioning agent inlet and a dust removal outlet pipeline; and the powdery conditioning agent inlet is connected with one end of a powdery conditioning agent conveying pipeline, while the other end of the powdery conditioning agent conveying pipeline is connected with a powder conditioning agent bin. In an emulsion preparation process of the powdery conditioning agent, the powdery conditioning agent and the sludge can be uniformly stirred in the preparation tank, and double processes of emulsion preparation and sludge coagulation are finished in the same device; and the sludge and the powdery conditioning agent are directly prepared into the emulsion, and a large quantity of tap water or reclaimed water consumption in an emulsion preparation process is not needed, so that the load and the consumption of the sludge treatment quantity are not extra increased to subsequent filter pressing and dewatering equipment.
Description
Technical field
The utility model relates to a kind of Sludge Chemical Conditioning device, relates in particular to a kind of powdery amendment emulsion preparation and throwing device.
Background technology
The at present domestic van-type plate and frame diaphragm filter press that more generally adopts carries out the sludge dewatering treatment technology generation for traditional sludge solid-liquid separation techniques such as original centrifugal dewatering of sludge, vacuum suction filter dehydration, belt filter press dehydrations, makes moisture percentage in sewage sludge reach the emission request of national regulation.
Solids in the mud mainly is made up of the electronegative colloidal solid of wetting ability, because PM for particulate matter is tiny and inhomogeneous, sludge water and sewage sludge solid particulate bonding force are very strong, and be bigger than resistance, so dewatering is relatively poor.In order to improve the performance of sludge dewatering, improve the effect of mechanical dehydration, need change the physico-chemical property of mud through conditioning, reduce the avidity of colloidal solid and water, for solid-liquid separation creates conditions.Sludge conditioning mainly comprises chemical conditioning, the temperature difference is modified and the mikrobe flocculation is modified.
Chemical conditioning is to use maximum mud hardening and tempering methods at present.Its ultimate principle is the amendment that can play electrical neutralization or adsorption bridging effect through in mud, adding; Like coagulating agent, flocculation agent, coagulant aids etc.; Destroy the stability of mud colloidal solid, make to assemble each other between the dispersive small-particle to be split into macrobead, thereby improve the dehydration property of mud.
The amendment that adds in the chemical conditioning process can be divided into pressed powder, liquid on form; Amount by a certain percentage is through directly adding or process the emulsion dosing method; Be transported in the conditioner that whipping appts is installed quantitatively mud and mix to reach and change the mud structure; Strengthen flco intensity, destroy colloidal stability, thereby improve the purpose of the dehydration property of mud.
Generally adopt in the present domestic sludge press filtration dewatering process: amendment directly adds with amendment emulsion and adds two kinds of addition methods.
Cause dust from flying to pollute production environment easily owing to directly add the powdery amendment, increase conditioner whipping appts structure and power, cause incomplete mixing to influence conditioning effect easily.Emulsion add be with the powdery amendment through with the emulsion addition method that is mixed and made into certain proportion concentration of liquid; Existing domestic and international mud generally adopts tap water or middle pigment powder amendment to be mixed with emulsion to carry out addition method with pump delivery again; Device structure is complicated and huge; Investment, place, working cost increase; The extra increase water yield causes follow-up filter-press dehydration technique operation hours to prolong, and the solid-liquid separation load strengthens, and the heat that the former water chemistry reaction of powdery amendment and mud is produced in the preparation emulsion process is to the modifying function forfeiture of enzyme in the mud.It is to improve the sludge conditioning effect that amendment mixes with mud full and uniformly, reduces the loss of amendment, accelerates follow-up mechanical dehydration speed, reduces the determinative of working cost.
In the powdery amendment system breast process, need evenly stir, therefore, invent a kind of simple in structure, economical and practical powdery amendment emulsion preparation and throwing device, seem particularly urgent with the mud in the sludge conditioning pond.
Summary of the invention
The utility model is directed against the deficiency that exists in the prior art, and a kind of simple in structure, economical and practical powdery amendment emulsion preparation and throwing device are provided.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
Preparation of powdery amendment emulsion and throwing device; Comprise the preparation jar, be provided with whisking appliance in the preparation jar, whisking appliance is provided with agitator motor and speed reduction unit and powdery amendment opening for feed; First position of said preparation pot sidewall is provided with inlet channel and emulsion discharge pipe; The upper surface of preparation jar also is provided with powdery amendment opening for feed and dedusting outlet conduit, and powdery amendment opening for feed place is connected with powdery amendment transfer line, and the other end of powdery amendment transfer line is connected with powdery amendment feed bin.
As preferably, said inlet channel is provided with pump.
As preferably, emulsion discharge pipe one end that connects on the said preparation pot sidewall is the rectangle outlet.Emulsion becomes rectangular-shaped fluid over-flow, and a preparation jar interior band dirt air communication is crossed the vertical hydraulic dust-removing effect that reaches spaced apart with rectangular-shaped emulsion spillwag chute of dedusting outlet conduit.
As preferably, said powdery amendment transfer line two ends are tightly connected with flexible materials with powdery amendment opening for feed and powdery amendment feed bin respectively.
The beneficial effect of the utility model is: in powdery amendment system breast process with the sludge conditioning pond in mud can evenly stir; Mud directly is mixed with emulsion; Not making needs water consumption in a large amount of tap water in the newborn process, follow-up filter-press dehydration equipment is not had the load and the consumption of extra increase mud handling capacity; The generation heat is utilized effectively to the modifying function of enzyme in the mud in the amendment preparation of powder process.A preparation jar certain altitude position, side is connected with inlet channel and emulsion discharge pipe; Inlet channel links to each other with the preparation pot sidewall through pump, pipeline; Guarantee that preparation jar interior mud is in certain liquid level; Make the powdery amendment mix with mud fully, the emulsion preparation is accomplished in same device with the dual process of coacervation of mixing of amendment and mud, thereby strengthens the sludge conditioning effect.The device top is provided with fly-ash separator, is used for collecting the dust that the powder process of adding is flown upward.It is spaced apart with the rectangle liquid level of rectangle discharge port formation that band dirt air communication is crossed the dedusting outlet conduit, and the amendment emulsion current that vertically liquidate reach dust removing effects.
