The invention relates to instrumentation of the process of oleum and multiple hydrate absorption of sulfur trioxide.

The purpose of the invention is to reduce the corrosive wear of equipment and reduce toxic gas emissions into the environment by eliminating fogging in the apparatus.

FIG. I shows the apparatus, a general view; in fig. 2 - a variant of the arrangement, where it interacts with the gas flow G, and then falls on the bottom plate 2 of the apparatus and is outputted through the clamp 9.

The gas flow G enters the housing 1 through the connector 8, successively passes the contact devices 4 and 3 and exits the device through the connector 6 located in the upper bottom 2.

It is advisable in the apparatus (Fig. 4) of the device 4, located below the perforation to drain the acid on the perforated plate 10, to perform a nozzle, bath plate, top view; in fig. 3 — for example, in the form of ceramic rings, Savant version of a perforated plate with channels for draining acid; in fig. 4 shows an embodiment of the apparatus, general view. The device consists of a body 1 with the bottom 15

shiga. This will reduce the corrosive wear of the apparatus in the zone of high acid temperature. Contact devices 3, located above the perm 2. At the height of the case 1, there are arranged a perforated plate 10, it is possible to make contact devices 3 and 4, which are dispensed with a thread-type, having more

Hell 5 acid, shtutsera 6, 7, 8 and 9 high compared with the nozzle effekdl gas output, acid supply, supply of active. In the apparatus of the proposed konsts, output acid, respectively. Between the temperature of the acid located

contact devices 3 and 4 set-20 above the perforated plate 10, allows

installation at the top made of

Lena perforated plate 10 with channels 11 and 12 for draining acid, and channels 12 are connected to a collector for supplying fluid 13. The lower ends of the channels 11 are located at the bottom of the bottom 2. The lower ends of the channels 12 are located at the surface of the contact device 4.

Based on the need to uniformly distribute the acid over the cross section of the housing 1, it is advisable to make the number of channels 11 and 12 equal.

The device works as follows.

The flow of acid L is fed into the housing 1 through the brush 7 of the acid distributor 5, flows to the contact devices 3, where

Invention Formula {. A device for carrying out the absorption of sulfur trioxide by sulfuric acid, comprising a housing with contact devices located at its height, an upper and a lower bottom, a clamp for introducing and withdrawing acid and gas, an acid distributor installed above the contact devices, characterized in that wear equipment interacts with the gas flow G, collects -, and reduces toxic gas emissions from the perforated plate 10, where the discharge into the environment due to the reduction of flow L flows into the channels 11, Yeni fogging in the unit, he provided with a collector between the contact devices for supplying the liquid part to the channels 12. A part of the acid stream, draining c into the channels 11 is transported along them to the bottom bottom 2. A part of the acid stream, draining the channels 40, to drain the acid, while the channels 12 are displaced with the liquid flow L, the fishing is connected to the collector and their ends are supplied through the collector 13. Through the number located at the bottom of the apparatus, the lecturer 13 can supply water or acid to the channels 12 with a concentration different from the concentration of the acid stream L. Due to pa after the acid is added, it is heated to 100-120 ° C, i.e. conditions are realized that ensure minimal formation of mist in the apparatus. Next, the flow of acid from the channels 12 flows to the surface of the contact device 4, the bones and the perforated plate from the channel are the ends of another part of the channels — near the surface of the underlying contact device. 2. An apparatus according to claim 1, characterized in that the contact devices located above the perforated plate are made cup-shaped, and those below are nozzle-shaped. where it interacts with the gas flow G, and then enters the bottom plate 2 of the apparatus and is discharged through the spider 9. The gas flow G enters the housing 1 through the connector 8, successively passes the contact devices 4 and 3 and exits the device through the connector 6 located in the upper bottom 2. It is expedient in the apparatus (Fig. 4) of the device 4, located below the perforated plate 10, to be packaged, for example, in the form of ceramic rings of the Ravannah plate 10, to be made packing, for example, in the form of ceramic rings Pa shiga.
