    In a process of removing liquid from a particulate solid material the material is passed through a row of upwardly open, elongated interconnected cells and superheated steam is introduced into said cells at their lower ends in a manner so as to impart to the particles a whirling movement, during which dried particles are lifted out of the cells and into a common transfer zone and from said zone down into a discharge cell with no steam supply. The dried material thus introduced into the discharge cell is discharged together with material which has passed the row of cells. …<??>The invention eliminates the need for effecting a preceding disintegration of the solid particulate material.

    专利说明:

    The invention relates to drying and can be used in the chemical and other industries to remove liquid from solid bulk material.
    The aim of the invention is to increase the efficiency of liquid removal from a solid material.
    FIG. 1 is a schematic of an installation incorporating a device for removing liquid from solid bulk material: FIG. 2 shows a device for removing liquid from solid bulk material, vertical section; in fig. 3 is a section A-A in FIG. 2; in fig. 4 - device with a heat exchanger placed in the core, vertical section; in fig. 5 section bb FIG. four.
    The device contains a cylindrical 8l. Vertical-1 case 1, an upper loading device made in the form of a screw conveyor 2 (auger) installed in pipe 3, which is connected to the feed hopper 4 through a sluice gate 5, a lower discharge device made in the form of a pipe 6c installed on it a screw conveyor 7, Pipe 6 is connected to a sluice gate 8. The upper part of Koh 5usa 1 is connected by pipeline 9 to a cyclone 10. At the bottom of the cyclone 10 a sluice gate 11 is provided, and the top of the cyclone 10 is connected through a pipeline 12 with an outlet 13 with a heat exchanger 14. The heat exchanger 14 has devices for supplying superheated steam (not shown) and devices (not shown) for removing condensate from it. The lower end of the heat exchanger 14 is connected to the lower end of the cylindrical vertical body 1 through a pipe 15 in which a fan 16 is installed.
    The cylindrical vertical housing includes a lower cylindrical section 17, an upper cylindrical section 18 of diameter than the lower section 17, a conical upper section 19. The upper part of the lower cylindrical section 17, as well as a conical section 19 of housing 1, are divided into vertical compartments 20 by radial partitions 21. The upper loading a device with a screw conveyor 2 is connected to the first in the course of bulk material compartment 20, and the lower discharge device with a screw conveyor 7 is connected to the last along the material from section 20. The compartments 20 (except for the latter) have bottoms 22, made in the form of gas distribution grids. The bottom 22 of the latter in the course of the material of the compartment 20 is made solid. In the lower part of the radial partitions 21 there are holes 23 with the exception of the radial partition 21 between the first and last compartment 20. In the lower part of each compartment 20 there is an inclined slope 24. In the area of the conical upper portion 19 in each compartment
    20 installed package inclined plates 25,
    placed in such a way that they serve both to distribute steam flows,
    passing through compartments 20 above the top
    0 a cylindrical section 18 with a large diameter and for collecting the particles contained in these steam streams and for directing these particles back towards the bottoms of the 22 compartments 20.
    5 At the upper parts of the inclined plates 25, there are two packages of inclined plates 26, also serving to collect particles contained in the steam streams, before these particles reach the exhaust chamber.
    0 27, and the crown of the twisting blades 28 installed on the outside of the stationary core 29 located in the center of the housing 1. The twisting vanes 28 form gaps 30 with the walls of the housing 1
    5 between the outermost ends of the twisting vanes 28 and the wall of the housing 1. The outlet nozzle 31 is connected to the pipeline 15.
    Bottom cylindrical portion 17
    0 is equipped with a steam jacket 32. In the gaps 30, rotatable blades 33 and a shutter 34 can be placed. Inside the core 29. In the form of a pipe, a heat exchanger 35 can be installed, in the bottom
    5, a blower 36 with a shaft mounted in bearings 37 is placed in the cylindrical section 17. A sloping ramp 24 having an inclination from the center of the housing 1 to the periphery is provided with a guide rod 38, spaced at an angle to the radial partition 21. In some compartments 20 there are additional directions rods 39 installed at the bottoms 22 and extending outwardly from
    The 5 ends of the guide rods 38 on the inclined slopes 24. The guide rods 38 and the additional guide rods 3Q are installed so that the material is sliding along the inclined slopes
    Q 24 and searching for 22 in the direction of the wall of housing 1, is directed towards the openings of the 23 8 radial Lereborok 21 from the previous compartment 20 to the next,
    5 The device operates as follows.
    The solid lump material introduced into the first compartment 20 through pipe 3 is forced to move up and down inside said compartment 20 in the direction indicated by the boom
    kami. This is due to the introduction of superheated steam through the bottoms 22, made in the form of gas distribution grids, due to the wedge-shaped form of the compartments 20 and due to the inclined slopes 24. During this vortex motion, the heavier part of the particles moves into the next compartment 20, and the lighter dried particles pass upward into the conical section 19 of the housing 1. If the particles are not caught by the inclined plates 25 or the inclined plates 26 arranged above them, they reach the vapor chamber 27. The dried particles are also introduced into the gas the KafMepy 27 from the compartments 20, having the bottoms 22 in the form of gas distribution grids, and during the period of movement in the internal exhaust chamber 27 these particles will pass faster or slower over the last compartment 20. As in the last compartment 20 there is no upward flow of steam fall down the compartment 20 in the direction of its bottom 22. The material is transported from the housing 1 by means of a screw conveyor 7.
    Par leaving the vapor chamber 27, enters the upper part of the housing 1 and further into the pipeline 9. During this movement, the steam passes through the crown of the twisting blades 28, which create a cyclone field, causing the particles entrained by the steam flow to move outward to the wall of the housing 1 Attaining this wall, the particles move down through the gap 30.
    The guides, rods 38, additional guiding rods 39 and inclined slopes 24 direct the particles from the previous compartment 20 to the subsequent compartment 20 through the holes 23 in the radial partitions 21.
    In this way, an increase in the residence time of the particles in each compartment 20 is achieved,
    Par coming out of the housing 1, comes through the pipeline 9 into the cyclone 10, in which additional separation of solid particles and steam is carried out. The separated vortex particles are discharged from the bottom of the cyclone 10 by means of a lock gate 11.
    Steam leaving the top of cyclone 10 passes through pipe 12 to heat exchanger 14, and excess steam is removed through outlet 13. After heating in heat exchanger 14, superheated steam is recirculated through pipe 15 and is fed through fan 16 to the zone under bottom 22 of housing 1 and further in compartments 20.
    The steam jacket 32 of the lower cylindrical section 17 of the housing 1 serves to maintain the steam in a superheated state. The device may also be provided with means for heating the partition walls. Additional heating surfaces may be installed inside the compartments 20.
    The device shown in FIG. 4 and 5, operates in the same way as the device shown in FIG. 2 and 3.
    Par leaving the vapor chamber 27, passes through a narrow gap 30 formed by the twisting blades 28 and the walls of the housing 1. The twisting blades 28 create a strong cyclone field, which rejects essentially all solid particles towards the wall of the housing 1 and causes them to collect in the annular gap 30 The particle accumulated there is transported to the shutter 34 by blades 33, and from the shutter 34 they enter the discharge compartment 20. After the exhaust of steam through the pipe 9 in the cover of the housing 1, the blower 36 will cause Shiys steam to pass through the heat exchanger 35 from its upper end through the lower end of the heat exchanger 35 and further into the area under the bottoms 22 and into the compartments 20.
