Description

Existing designs of desulfurization boxes with horizontal shelves or tower-type are very bulky, heavy, and require costly accessories (cats, bridge and gantry cranes, etc.) for their maintenance.

In view of the inconvenience of servicing, the caravans usually count on a long time of exploitation without changing the desulphurization mass, which means that they are even larger, more difficult and more difficult to maintain.

The proposed design of chamber desulfurization differs from the existing ones in that the loading and unloading takes place almost without the cost of labor for the worker.

Loading and unloading operations can be carried out every day, according to which the size of the desulfurization chamber is much smaller than with the tower and tower installations of the same capacity. In addition, the small size of the boxes makes it possible to increase the cleaning ratio, which ensures the completeness of gas cleaning from impurities.

Due to the above advantages, chamber desulfurization provides significant savings in both capital and operational costs with better gas cleaning.

In addition, the economy of the occupied territory will also play a role in reducing the cost of installation.

The chamber desulfurization box shown in three projections on the attached drawing, in FIG. 1 is a vertical longitudinal section; FIG. 2 in horizontal and in FIG. 3- in a transverse vertical section, consists of an iron welded box /, loading hatches with covers 2, discharge hatches with covers 3, entrance 4 and output 5 branch pipes.

The box is broken inside by the iron walls into the gas distribution 6 and the gas collection chamber 7. Iron frames with mesh partitions Y are installed vertically between the inner walls. Absorption mass is poured into the chambers formed by the nets through loading hatches // - bog ore with sawdust or waste of alumina slimes. The interstitial spaces form the inlet 8 and outlet 9 gas channels. The channels formed by the grids are alternately closed at one or the other end by partitions 12 for forcing the gas through the chambers.

Absorption mass for loading may be supplied by a bunker on an overhead road or by a belt conveyor with a mobile breakwater. For the convenience of unloading and transporting the spent mass, the desulfurization box is raised above the ground and mounted on a welded frame.

The waste mass is poured from the chamber into the trolleys and is taken away. Trolley can be replaced by a belt conveyor.

The principle of chamber desulfurization is similar to that in the casement and tower desulfurization. Gas passage through the layer. desulfurization mass is cleaned from harmful impurities. As sulfur is deposited, the absorbing mass may solidify and will not fall out of the chamber during unloading. To eliminate the solidification of the mass, the absorption process is carried out in parallel with the recovery process with the addition of live steam, which does not allow the mass to solidify. For better loss of mass, the frame with grids can be installed not strictly vertically, but slightly inclined;

at loading hatches the section will be less, than at unloading hatches.

Caking will not take place, as the mass is in operation for a short time, and also blowing with steam helps to preserve the original state.

The subject matter of the invention.
