Description

(54) MULTIGIDROCYCLONE

one

The invention relates to a device for separating suspensions under the action of potent forces and can be used in chemical, microbiological and other industries.

Known battery hydrocyclone, including chegfe hydrocyclone placed on the perimegro circle, the common supply, the collector communicated with the input nozzles of single hydrocyclones. A drain chamber for collecting the clarified liquid of single hydrocyclones adjoins the collector coaxially on the top, and a slurry chamber for collecting the condensed solid product C 1 is also located below.

The closest in technical essence and the achieved result is a multi-hydrocyclone containing single separating elements with tangential inlet, drain and Sand pipes, common supply, drain and sand chambers connected to the corresponding branch pipes of separating elements located in the central part of the multi-speed cyclone drain pipe, through which The drain chamber is connected to a sand chamber f 2 J.

During the treatment of low concentrated suspensions in this multihydrocyclone, the solid fraction is condensed in single separating elements and discharged into the sand chamber, in the bottom part of which its accumulation and compaction takes place, and the liquid phase, freed from solid particles, is displaced upward through the smallest suspension, and is displaced upward through the sediment through the smallest suspension, upwards through the sediment, up to the bottom through the sediment, is removed. feed chamber into the cavity of the drain chamber. Control valve

15, regulation of the discharge of the settled liquid phase into the clarified chamber is provided.

A disadvantage of the known device is that, when achieved in this

20, an apparatus with a high degree of condensation of low-centered suspensions exits a fine fraction from the sand chamber through an axial tube into the drain chamber. This is due to the high production of the hydroclone and the slow time of the sludge. The purpose of the invention is to increase the efficiency of separation of low concentrated suspensions by eliminating the removal of small fractions from the sand fraction into the slurry. The goal is achieved by the fact that a multihydrocyclone, contained single separating elements with tangential inlet, drain and sand-bushing branch pipes, common supply, drain and sand chamber connected to the corresponding branch pipes of separating elements, located in the central part of multihydrocyclone drain pipe through which the drain the chamber is connected to a sand chamber; it sleeps with a hollow cylindroconic, with a swirling element and with a bell that adjoins its cylindrical part, while The chute is located inside the sand tube, the open end of the drain pipe is located inside the conical part of the element, and the swirler is installed at the junction of the cylindrical part of the element with the socket. Due to such a constructive implementation, the upper sludge of the sand chamber is processed into an oprociprocological housing with the output of the clarified liquid phase through an axial tube, recessed into the cavity of the cone, into the common drain chamber and with a discharge of the selected fine fraction through the gap between the apex of the cone and the axial tube And further through an additional pipe from the apparatus. FIG. 1 shows a general view of a multi-hydro cyclone in section; FIG. 2, section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 1. The multi-cyclone cyclone comprises a housing 1. Around the housing 1 in a circle are mounted the separating elements 2. The housing 1 is divided by height into partitions into three chambers: the upper-discharge chamber 3 for collecting the clarified liquid, the medium-feeding chamber 4 suspensions in separating the elements 2 and the lower-sand chamber 5 for collecting the solid fraction previously condensed in the separation elements 2. In the upper part of the sand chamber 5, there is an overturned cylindro-conical element 6, in the lead-in part of which there is a conical socket 7 immersed in the cavity of the sand chamber 5. The cylindro-conical element 6 at the junction with the conical socket 7 is equipped with a lead-in screw device (swirler) 8. The conical socket 7 delimits the descent and rise of stream flows of the sand chamber sealing zone 5. The cone of element 6 is adjacent to the supply chamber 4 with a gap. The axial tube 9 is recessed into the cavity of the cone and communicates the drain cavity 3 amers zone refining element 6. Verschina cone element 6 abuts with clearance to the axial pipe 9. The lower part of the housing 1, the female cone element with a gap 6 is provided with a pipe 10 for discharging a concentrated solids fine inclusions. The shank of the drain chamber 3 has an axial pin 11 with a valve 12 adjoining the axial tube 9. A valve 14 is installed on the discharge port 13 of the sand chamber 5, the Multihydraulic cyclone works as follows. The initial suspension under pressure through the feed chamber 4 is distributed into single separating elements 2, where the suspension is divided into condensed and clarified streams. The condensed slurry stream is discharged into the sand chamber 5, and the clarified liquid is discharged into the drain chamber 3 and further to its intended purpose. In the sand chamber 5 preliminarily condensed in single separating elements 2, the solid phase falls into the zone located under the conical socket. 7, where it is closed when the discharge port 13 is closed, accumulated, sealed. The liquid phase with a part of the fine solid fraction, displaced upward, is guided through the socket 7 to the lead-in screw device (swirler) 8 of the overturned tapering rod 6 and is intensively twisted in its cavity. At the same time - hard. the fraction due to the centrifugal effect moves to the walls of element 6 and from the cone tip through the annular gap enters the cavity formed by the lower part of body 1 and the cone of element 6 and then passes through the nozzle 1O from the apparatus. The liquid clarified in element 6 is discharged through an axial tube 9 into a drain chamber 3, where it is combined with a common clarified flow. The compacted sludge is periodically discharged by the valve 14. When the multi-hydro cyclone is operated, the sand chamber 5, with the valve 14 closed, operates under pressure, but the output of the dried product through the nozzle

10 of element 6 is free, so a normal differential is created for its operation.

Thus (the proposed design of a two-hydro-cyclone, due to the introduction of new structural elements, ensures a high quality liquid clarification with a high degree of thickening of the solid phase.

Use of multi-hydraulics

With a capacity of 12O m / h on the st-adnn separation of the yeast suspension before feeding it to the separation in the microbiological industry will provide significant savings.

The service life of COS separators in this process is about 5 years. The proposed multihydrocyclone design will provide almost complete separation of abrasive impurities before separation, and this will significantly extend the service life of the separators. A single bale, a 12O thihydrocyclone, serves five separators. At increase in service life of separators twice

The economic effect of using multi-cyclone will be 120 thousand rubles.
