SU613185A1 - Drying drum for evaporation of solutions - Google Patents

Description

the sections and separation of the residue from the nozzle is carried out without transporting it.

FIG. 1 shows a sushnlny drum, longitudinal section; on nat. 2 - te, cross-section.

Drying drum for you: the parzann of the solutions contains a rotating case / with Drive 2, camera 3 for inlet and ka.: Enu4 for discharging heating, discharge chute 5 for discharging solids, pipe}: juvsa 6 .dl for supplying pacrBOipoB, gas supply for example, perforated, outer lgregoro,: 1ku 7 and -output wall 5, spaced coaxially / and fixed on the front end wall.kex 9, central) 3G1m. hole 10 on diam. l) e 1.:1 of the morning septum S and back ) her t;) segpoi //, performed by erfo:) ireza.gno: 1 in the area between the outer area of 7 d drug zhnoy wall of the housing /.

Depending on the magnitude of the lag of 12 and the properties of the sludge being processed, it is necessary to fill the ring volume of the pass; 1y: oh is 60-95%. In the case of an error, - ;; 1; partitions 7 and 8 konu.soob) aznyh corpus ;; / Essentially, the drum is installed with the slope so that the forming taper of the partitions 7 and S must be parallel to the short circuit.

The dry drum works in the following way.

The initial solution is fed into the rotating housing / through the pipeline 6, which irrigates a part of the surface of the inner non-housing 8 along its entire length. The gaseous coolant enters the chamber o, passes the partition 6 wetted with a solution, the nozzle layer J2 and the partition 7, heats up and, together with the moisture vapor, is discharged through the perforations in the wall // into the chamber 4, where it is removed. During one turn of the body around the axis, the solution dries out on the surface of the nozzle 2, separates the residue from its surface, shreds and removes the flow of coolant through the gas-expanding Ieregorodka 7 and the chamber to the discharge chute 5.

Due to the presence of a transversely bedable layer of the nozzle 12, formed by placing it between two perforated shafts 7 and 8, it is possible to reduce the heating operation of the nozzle.
