Description

Изобретение относитс к пищевой промьоиленности, а именно к конструктивному вьшолнению тарелки дл эпюрационных колонн. 5The invention relates to the food industry, in particular to the constructive implementation of a tray for epillary columns. five

Известна тарелка дл эпюрационных, колонн, снабженна трубчатой переливной системой и СОСТОЯЩИЙ из отдельных коаксиально расположенных и последовательно соединенных конусооб- |0, разных перфорированных секций, перфораци которых представл ет собой отверсти с отогнутыми кромками pQ,.The famous plate for epuration, columns, equipped with a tubular overflow system and a CONSTANT from separate coaxially arranged and series-connected cone-| 0, different perforated sections, the perforations of which are holes with bent edges pQ ,.

Недостаток указанной тарелки заключаетс в том, что она не обеспечивает j необходимого увеличени поверхности контакта фаз и уменьшени уноса.The disadvantage of this plate is that it does not provide j with the necessary increase in the contact surface of the phases and decrease in entrainment.

Целью изобретени вл етс увеличение поверхности контакта фаз и уменьшение уноса.20The aim of the invention is to increase the contact surface of the phases and reduce entrainment.

Цель достигаетс тем, что в предлагаемой тарелке кажда секци выполнена в виде усеченной шаровой поверхности так, что верхн наружна кромка предыдущей секции, счи- 25 та от центра тарелки, перекрьшает нижнюю внутреннюю кромку последующей секции и соединена с ней усеченным конусом, причем над казкдой секцией по наружному диaмeтpV расположены j0The goal is achieved by the fact that, in the proposed plate, each section is made in the form of a truncated spherical surface so that the upper outer edge of the previous section, viewed from the center of the plate, intersects the lower inner edge of the subsequent section and is connected to it by a truncated cone, and above this section on the outer diametrV located j0

Кроме того, йаправл кхцие пластины установлены в наклоном, противопО ложшм направлению отогиутых кромок , а под плоскостью усеченной шаровой поверхйорти у Кс1 пого отверсти перфорации с противоположной стороны отогнутс ) кромки установлена дополнительна пластина.In addition, the yxplate plates are installed in an inclination, opposite to the direction of the cut edges, and an additional plate is bent under the plane of the truncated spherical surface at X1 of the perforation hole on the opposite side.

Claims

Plate for Esho | The columns are placed in the housing 1, provided with a tubular overflow system 2 and consists of separate "oaxially arranged and series-connected cones of perforated sections 3, whose perforations are openings with bent edges 4. Each section 3 is made in the form of a truncated spherical surface, moreover, the upper edge of the previous section is connected to the lower edge of the subsequent section by a truncated cone 5 and overlaps it. Above each section 3, horizontal rings 6 and vertical annular partitions 7 are installed, made in the form of cylinders 8 and truncated cones 9. Vertical annular partitions 7 are provided with guide plates 10, fixed with an inclination, in the OPPOSITE direction of the bent edges 4. Under the plane truncated An additional plate 11 is mounted on the ball surface of section 3 at each perforation hole on the opposite side of the bent edge 4. The operation of the epraying column tray is as follows. The steam flow is fed from below into housing 1 and rises upwards. Passing through the holes with the bent bristles 4, it acquires the direction of the screw movement. The liquid flows from the overlying plate to the center below through the tubular overflow system 2. The fluid being captured by the steam is rotated on the sections of the 3 plates and centrifugal forces are thrown to the periphery. In sections 3, a rotating gas-liquid layer arises, having a radial direction of movement. The truncated spherical surface of sections 3 ensures uniform distribution of liquid across the section and eliminates gas phase overshoot. and a truncated cone 9 of the annular partition 7. In the subsequent section, the movement of the gas-liquid layer and the interaction of the phases is repeated. Having reached the overflow pocket 13, the liquid cpekaet into the underlying plate through the tubular overflow :; system 2. Const;: the trays for the epitaptation columns allow the possibility of increasing the surface of the contact of the phases and reducing the cut. Claim 1. A plate for epuration columns, provided with a tubular overflow system and consisting of separate coaxially arranged and successively connected cone-shaped perforated sections, the perforations of which are slots with angles; in order to increase the contact surface of the phases and reduce entrainment, each section is made in the form of a truncated spherical surface so that the upper outer edge of the previous section, starting from the center of the plate, overlaps the lower inner the morning edge of the subsequent section is connected to it by a truncated cone, with horizontal rings above the outer diameter section and horizontal vertical annular partitions aligned with the latter with guide plates, forming an annular passage with the truncated cone.

2. A plate according to claim 1, wherein the guide plates are installed with an inclination opposite to the direction of the bent edges, and an additional plate is installed under the plane of the truncated tsarter surface at each hole of the perforation on the opposite side of the bent edge. .
