Description

A kind of continuous flocculator

Technical field

The present invention relates to a kind of continuous flocculator equipment that is used for flocculating and purifying fermentation liquor or sewage.

Background technology

The flocculation separation technology thereby is widely used in the purified treatment of zymotic fluid in the fermentation industries such as pharmacy, food because but its energy consumes separate impurities such as thalline and albumen in the low forced fermentation liquid, simplifies the zymotic fluid post-processing operation, improves removal of impurity.But because zymotic fluid is the complex system that contains plurality of impurities, make that flocculation separation technology clean-up effect aborning is unsatisfactory, cause the subsequent extracted of tunning and the low or poor product quality of yield of purifying.In today that the fermentation technique level improves constantly, tunning isolation technics level relatively lags behind, and isolation technics has become the bottleneck of fermentation industry productivity effect.Therefore, how removing impurity as much as possible to alleviate the burden of subsequent separation process on source (zymotic fluid), is the important topic that fermentation industry faces.

Container experiment method (jar testing, be the flocculation separation method of operating at intermittence that container adds agitator) be general flocculation separation method in the at present domestic and international flocculation field, it can provide the otherwise effective technique operating parameter for the zymotic fluid flocculating setting separation process of intermittently operated; Yet when the container experiment method was used for the flocculation separation continuous flow procedure of fermentation industry, the zymotic fluid solid-liquid separation effect is variation obviously.Its reason is: in continuous flow procedure, it is broken that floccule body particle in the flocculation after fermentation liquid easily is transferred process institute, and the flocculation time of each floccule body particle is different in size, cause floccule body particulate filtration or sedimentation difficulty to increase, thus the obvious variation of solid-liquid separation effect of feasible flocculation after fermentation liquid.At present the invention of relevant flocculator concentrates on sewage flocculation purified treatment aspect mostly, mainly be solve flocculant and sewage fast, abundant mixed problem, and it is considerably less to be used for the invention of flocculator of flocculating and purifying processing of zymotic fluid of component complexity.

Summary of the invention

At present zymotic fluid flocculation technique present situation, the present invention proposes a kind of flocculator of novel structure, make granularity, size distribution and the flocculation time of zymotic fluid floccule body particle in the flocculation process all controlled, with the deficiency that overcomes said vesse experimental method flocculation apparatus, significantly improve the zymotic fluid solid-liquid separation efficiency.

Structural representation of the present invention is seen Fig. 1, Fig. 2, Fig. 3, Fig. 4 and the Fig. 5 in the accompanying drawing.Flocculator (Fig. 1) is made up of container (1) and built-in group on-gauge plate (2), and container (1) is made up of cylindrical shell (3) and upper end cover (4) and bottom end cover (5).Group on-gauge plate (2) becomes many passages (7) with the spatial division in the shell (3), the axis of many passages (7) is parallel with the axis of container (1), the ratio of the catercorner length (a) of the cross section of every passage (Fig. 2) and the axial length (b) of this passage (Fig. 1) is between 0.001～0.25, group on-gauge plate (2) is placed on the feet (6) of shell (3) bottom, feet (6) has four, evenly distributes to be fixed in the bottom of shell (3).Fig. 4 and Fig. 5 are two typical composing plates in group on-gauge plate (2) structure.

This novel flocculator is vertically installed, the zymotic fluid top from flocculator after fully mixing that is added with flocculant feeds continuously, flow in formed each the bar passage of built-in group on-gauge plate, flow out from the flocculator bottom continuous-flow flocculation back, and inflow filter or sedimentator carry out Separation of Solid and Liquid again.The formed continuous flocculation passage of group on-gauge plate in the flocculator is owing to be column, so can make the material back-mixing degree that wherein flows less, thereby make each mobile floccule body particle that the consistent time of staying be arranged, thereby zymotic fluid floccule body particle easy to control makes it have narrower size distribution; The length of flocculation passage can be controlled the length of the floccule body particle time of staying continuously, makes it have bigger granularity thereby can control the floccule body particle, and the floccule body particle is difficult for broken in the flocculation process that flows slowly.When the floccule body particle has narrower size distribution and bigger granularity, help improving the isolated by filtration and the sedimentation separation efficient of zymotic fluid floccule body.

Group on-gauge plate in the novel flocculator is a stand-alone assembly, puts it in the container, is supported on four feets of shell bottom and get final product, does not need to fix in addition.Therefore the installation of flocculator, dismounting and cleaning all make things convenient for.

If replace this novel flocculator with conventional fixed tube-sheet exchanger, with the tube bank in the fixed tube sheet as the continuous-flow passage that flocculates, then the fixed tube sheet type flocculator is compared with this novel flocculator, not only complex structure, difficulty of processing are big for the former, and because the space outerpace of the tube bank between two tube sheets is not the flocculation passage, make that the equipment volume utilization rate of fixed tube sheet type flocculator is lower than the equipment volume utilization rate of novel flocculator, thereby make the manufacturing of fixed tube sheet type flocculator and use cost all be higher than novel flocculator.Simultaneously because the group on-gauge plate of novel flocculator inside does not bear the pressure reduction inside and outside the container in flocculation process, and the tube bank in the fixed tube sheet type flocculator need be born inside and outside differential pressure in flocculation process, therefore organize on-gauge plate and can adopt the lower material of intensity (even plastic or other material) manufacturing, can further reduce manufacturing cost, and the tube bank in the fixed tube sheet type flocculator need be adopted the higher relatively material manufacturing of intensity, makes its manufacturing cost further improve.

Be placed on the group on-gauge plate that replaces in the shell in the novel flocculator if adopt many single tubes vertically to arrange (tube and tube be parallel to each other contact), do the equipment volume utilization rate that also can improve flocculator outwardly like this, and the requirement of strength to the single tube material is not high yet, but because of the small space between the tube and tube is easily stopped up by the floccule body particle, make the flocculation of can't flowing of space between the tube and tube, so in fact can cause the equipment volume utilization rate of this flocculator to reduce.

In sum, the present invention is because structurally different with other flocculator, thereby make novel flocculator not only can control the solid-liquid separation efficiency that the granularity of zymotic fluid floccule body particle, size distribution and flocculation time improve zymotic fluid, and can make that novel flocculator is simple in structure, easy to maintenance, manufacturing and use cost be low, compare with other zymotic fluid flocculator to have obvious superiority.

The research of this novel flocculator obtains grant of national natural science foundation (subsidizing bullets 20676063).
