    In venturi coolers for flue gas desulphurisation plants, in which water is sprayed in by means of water spray nozzles (3) through tubes (2) arranged transversely to the longitudinal direction (1) of the cooler, the effectiveness of the sprayed water depends on the velocity of the flue gases not falling below a limit. To increase the flow velocity at low flue gas rates arising, the cross-section has been reduced by means of internals, which are expensive to install, on the wall of the venturi cooler. A simple adjustment of the cross-section of the venturi cooler to the particular flue gas rates arising can be accomplished by means of baffles arranged on the tubes (2), which baffles reduce the flow cross-section of the venturi cooler and leave the outlet of the water spray nozzles (3) free. These baffles can be formed as rotatable cylinders (4), surrounding the tubes (2), with pivotable lugs (5) for rapid adjustment of the cross-section. …<IMAGE>…

    spraying water, the cylindrical elements 4 are mounted coaxially on the pipes 2 with the possibility of rotation and a rapid change in the cross section. Shin guards can be pairwise connected to form
    sharp or rounded edges and may have a width equal to the distance between the pipes 2. Elements 4 have an extension of length within the angle of rotation of the element 4. 4 Cp f-ly, 8 ill.
    The invention relates to a Venturi cooler for a flue gas desulfurization device with several tubes arranged across the longitudinal direction of the cooler with nozzles for spraying water. In a refrigerator of this type, it is important for the efficiency of the sprayed nozzle to maintain the speed of the smoke flux within a certain interval,
    Fig. 1 shows a venturi tube for installing flue gas desulfurization with cylinders surrounding the tube; a section; Figures 2 to 4 show various types of embodiments of a Venturi cooler, incision, with cylinders surrounding the pipes, and rotatable plates; figure 5 - venturi refrigerator. with swivel shields attached to pipes; Figures 6-8 are embodiments of tubes with cylinders and shields,
    The venturi scrubber for a flue gas desulfurization plant contains several longitudinally located across. the direction of the housing 1. pipe 2 with nozzles 3 for spraying water. The cross-section of the refrigerator is narrowed by partitions, which leave the nozzles 3 free to spray water. These barriers consist of cylindrical elements 4, surrounding pipes 2 and leaving nozzles 3 free to exit.
    The cylindrical elements 4 (Fig. 2) are connected to control partitions in the form of flaps 5, which extend in the direction of flow, which coincides with the longitudinal direction of the refrigerator 1. The rotatable flaps face with their wide part in the direction of flow, while the width is equal to the distance between the two pipes 2. Cylindrical elements 4 with pipes 2 are installed with the formation of the Venturi channels 6.
    The swivel plates 5 (FIG. 3) are connected on both sides with a rotating cylindrical element 4. The plates are made of ligated metal and have a connection in the lower end in the form of a sharp edge. They can be joined at the lower sharp edge by welding or flanged, but it is easier to make them in one piece and before
    the connection with the cylindrical element 4 to bend on the edge.
    4, the bottom connection of both flaps is rounded. The pipes 2 are rotatably mounted around their axis,
    Scrubber works as follows.
    Cylindrical elements, 4 (figure 1) in
    Depending on the degree of desired reduction of the cross section, they are mounted using one or several pipes 2, for which the pipes are removed and then re-installed in the Venturi scrubber.
    In accordance with figure 2, the cross section is reduced without dismantling and mounting by rotation of the cylindrical elements 4, thereby reducing the rotation of the flaps 5. The position of the flaps with the smallest transverse
    cross section is shown by strokes. In the same way, the transverse diameter of FIGS. 3 and 4 decreases, and, due to the connection of each two parts of the flaps 5, their high stability is ensured at the lower end.
    Referring to Fig. 5, the cross section is modified by rotation of the pipes 2, in which rotation and the flaps 5 are made.
    In order to fit
    a cross section to the relevant requirements; cylindrical elements are placed on the pipes 2. They reduce the cross section of the gas flow of the Venturi scrubber and open the outlet of the nozzles 3 that spray water. Since the pipes 2 for water-spray nozzles are easily accessible, easy and removable, the installed cylindrical elements 4 can open the openings 7 of the spray nozzles 3 and also easily reduce the flow cross-section. The holes 7 have an extension within the angle of rotation of the element 4. The pipes 2 serve herewith as supporting means for
    elements 4. Elements 4 can be made of glass fiber reinforced synthetic material (FGC), etc. Due to the fact that the pipes 2 are equipped with cylindrical elements 4, you can quickly and flexibly
    adapt to those WHI other production conditions. By maintaining a favorable range of the flue gas flow rate, it is possible to operate with a relatively small amount of sawn water and use a small pump for this water.
    The device can be performed as follows.
    Due to the fact that the partitions are the surrounding pipes 2, the cylindrical elements 4 with openings 7 in the area of the nozzles, they are easy to install by simply pushing them onto the pipes. The holes 7 may be in the form of individual holes of the nozzles or a through slit in the line of the side surface of the cylindrical element 4 of sheet material.
    The change in the flow cross-section during operation under the conditions of varying amounts of flue gases can be carried out using rotatable flaps 5, which extend in the longitudinal direction of flow, with which partitions are fitted (Fig. 2.6).
    Due to the fact that the swivel plates 5 are located with their wide part equal to the distance between the two pipes in the direction of flow, turning the plates 5 close to the adjacent pipe can almost completely block the free cross-section of the Venturi scrubber.
    The rotation of the flaps 5 can be facilitated by the fact that the flaps are fixed on the cylindrical elements surrounding the pipes, with the possibility of rotation on them, and the apertures 7 of the cylindrical elements are chosen such a size that they leave the nozzles open in any position.
    The good stability of the rotary flaps 5 with favorable flow of the flow is achieved by the fact that every two flaps on both sides of the axis of the rotating cylinder are fixed on it and the flaps 5 are connected at the lower edge. This connection can be made with the formation at the bottom of the sharp edge 8 (Fig.7). In addition, the connection may be rounded,
    so that both connected from two sides with the cylinder of the shield should run approximately parallel to each other (Fig. 8). The connection of the flaps 5 with a sharp edge 8 along the edge is advantageous in hydrotechnical relation because the flow from the sharp edge (with the dispersion of droplets) is disrupted. The connection of the flaps 5 with the rounded edge 9 also has some advantage.
