Abstract

The invention can be used in the chemical, metallurgical, mining industry in wastewater treatment technology, phase separation slurries. The purpose of the invention is to intensify the phase separation process. The device for separating the suspension comprises a housing with a perforated partition and a plate nozzle, which divide the cavity into a drain chamber, a separation compartment and a filtration compartment, which differentiate the suspension flow with simultaneous separation of the solid phase into size classes, sedimentation of the solid phase in thin layers and filtration through a vertically positioned filtering granular layer. 1 il.

Description

The invention relates to the separation of the phases of concentrated suspensions and can be used in the technology of wastewater treatment, waste and process solutions from granular and drip materials, for example, in the chemical, metallurgical, mining industries.

The purpose of the invention is to intensify the separation process.

withdrawal. The pipe 15 provides for removal of the light phase as it accumulates with a layer of under-lid 12.

Thanks to compartment 14, separation of impurities with a density lower than the density of the dispersed medium is achieved, and thereby, silting of the filtering layers during filtration is reduced. In addition, conditions are created for an abrupt change in the direction and speed of the flow of the suspension, which is shown in the drawing as proposed 10 contributes to the separation of the solid phase and its arrangement. The layers move along an inclined surface. The unidirectional movement comprises a housing 1 with an inclined wall 2 of the solid phase and a liquid in the compartments with a spout and a branch pipe 3 introducing the initial suspension. promotes the transition of the solid phase from the compartments 8 A perforated partition 4 is installed at the wall of the casing opposite to the inclined wall of the wall 2 with the formation of a drain chamber 5, in the lower part of which is located the branch pipe b of the clarified suspension. In case 1 parallel to the slope 10 and removed from the device. The vertical arrangement of the perforated partition provides filtration through a relatively thin renewable filter layer, which is formed either directly from the solid phase.

2, a package of inclined slurry 20 is placed, or by introducing into the flow the source plates 7 separating the cavities of the body on the suspension of the filtering granular mantle precipitating slit compartments 8. of the material, which in the separation process is a perforated partition 4 and lower portions almost completely stand out in the edges 9 of the plates 7 form, zone 10, zone 10.

filtration with an increasing cross section kTak, for example, when separating the suspension tube 11 of the solid phase. A cover of a sia containing 33 g / l of limestone slit 12 of housing 1 and the upper edges 13 are 3–1 mm (5%) flat particles, 1–0.5 mm of type 7 form less than 0 in the upper part of the hull (85%) , 5 mm (10%) and petroleum products, the proposed device provides for phase separation to the residual content of the separation section 14 of the light fraction removal.

The initial suspension is supplied to the upper part of the housing 1 through the inlet nozzle 3 and moves along the separation compartment 14 in the direction of the nozzle 15 for withdrawing the light phase. As you move above the perforated surface, while

of comparative size, the cleaning effect is 30% of what has been achieved by the compartments 8, in which downward flows in the form of mono-suspensions move to the filtration zone 10, where it is filtered through the accumulated solid phase. Since slurry with the largest particles of the solid phase enters the top filtration zone 10, and slurry with all the smaller particles of the solid phase enters each subsequent compartment of the inclined plates 7, then

a multi-layer filtering layer is formed with a maximum porosity of approaching and, therefore, maximum filtering capacity, with its ability.

The pressure and hydrostatic pressure of the liquid on the filtering layer from the lower parts of the compartments 8 contribute to the transfer of the accumulated solid phase from the compartments 8 to the layer of zone 10 during the filtration process, while the clarified heavy liquid phase
