The invention relates to the production of sulfur from gases.

A device for obtaining sulfur from gases, comprising a housing and a surface for condensation and crystallization of sulfur, made in the form of rotating around a horizontal axis of the two coaxial perforated cylinder with a nozzle between them, the device is equipped with radial partitions located between performi partitions, the width of which is made not less than the distance between the radial walls around the circumference of the corresponding cylinder [1] .

The device allows you to perform the process of obtaining sulfur continuous, however, the degree of extraction of sulfur when it is low.

The aim of the invention is to increase the degree of extraction of sulfur.

The goal is achieved in that the device includes a housing and rotating around the horizontal axis of the two coaxial perforated cylinder with a nozzle between them, and provided with radial partitions located between the perforated cylinder and positioned in the inner cylinder and between the housing and the outer cylinder of the longitudinal walls, the width of which is made not less than the distance between the radial walls around the circumference of the corresponding cylinder, the longitudinal walls of the inner cylinder equidistant offset in the direction of rotation of the ring of the drum relative to the partitions between the housing and the outer cylinder, and the size of their overlap is equal to the distance between the radial partitions on the circumference of the internal cylinder.

The proposed device is different from the OS is NTO shifted in the direction of rotation of the ring of the drum relative to the partitions, forming an external reservoir, and the amount of their overlap is equal to the distance between the radial partitions on the circumference of the internal cylinder.

Comparison of the proposed technical solution with other solutions, including adjacent areas of technology, showed that this distinctive feature as functionally independent can be found in known in the art solutions (as the principle of offset).

However, it was not possible to presuppose that the proposed change in the relative positions of the longitudinal partitions in the known device will allow to increase the degree of extraction of sulfur from gases. This property cannot be determined on the basis of the analysis of the new relative position of the walls and not associated with other signs of technical solutions and their interaction. That is, a causal relationship between the hallmark of the proposed technical solution and the new object property solution was not obvious. No laws on this account was not found.

On the basis of the alleged novelty of a causal connection between the distinctive characteristic of the proposed technical solution and projavlennyj, and the proposed solution meets the patentability criteria of "Substantial differences".

The drawing shows a cross section of the device with the desired location of the longitudinal partitions, which form six collectors I-VI (three external and three internal to the circular drum). The device comprises a coaxial perforated cylinders 1 and 2, forming rotating around the horizontal axis of the annular drum. The drum is provided with radial partitions 4, dividing it into sectors 3, and is located in the housing 5. The sectors are filled by the nozzle or the active catalyst. The longitudinal walls 6 form the internal and external collectors. Walls forming an internal reservoir, displaced circumferentially in the direction of rotation of the ring of the drum on opposite walls forming the outer reservoir so that their mutual overlap is equal to the distance between the radial partitions on the circumference of the internal cylinder. The collector 1 is designed to supply hot gas Stripping of elemental sulfur during regeneration of the catalyst, II - for the removal of sulfur gases, III - for the removal of cooling air, IV - for the supply of sulphur gases, the giving of air.

The device operates as follows.

Sulfur gases enter the manifold IV, pass through the sectors 3, filled with nozzle or a catalyst, which is the interaction of serosoderjaschei gases and/or condensation of elemental sulfur, and discharged from the reservoir II. During the rotation of the drum catalytic mass moving into the area of Ottawa. Hot gases of Ottawa served in the collector 1, pass through the catalyst, regenerate it and disposed of collector V. collector V gases containing elemental sulfur, passing the condenser, furnace deaf heating and again served in the collector I. Freed from sulfur catalyst as the rotation of the drum moves in the area of collectors III-VI (cooling). Here air coming from the collector VI, and exhaust from manifold III the catalyst is cooled to the adsorption-catalytic process temperature (80-130aboutC) and newly moved to the area collectors IV-II (communication and retrieval).

The device has three zones of flow of gas through the annular drum and three "dead zones", where the longitudinal partitions overlap the surface of the inner and outer cylinders. On these sites do not go there to continue. The mutual shift of the partitions may affect the nature of the processes by changing their duration and intensity. Redistribution zones of Ottawa, condensation and regeneration, therefore, may also influence the release of sulfur. The essence, perhaps, that when the claimed location of partitions (unbalanced, with a shift of) the inner surface of the perforated cylinder is covered later than the outside surface with respect to the same sector. This gives you the opportunity to "push" at least some "reversible" portion of gas in the collector and to prevent small amounts of gas in the adjacent collector (for example, hot gases of Ottawa sulfur in the reservoir of the cooling air, and so on).

This effect is particularly noticeable in cases where the device in addition to the processes of condensation of gaseous sulphur is the chemical reaction of the sulfur gases with the formation of elemental sulfur.

Apparatus FOR producing SULFUR FROM GASES, comprising a housing, a surface for condensation and crystallization of sulfur, made in the form of rotating around a horizontal axis of the two coaxial perforated cylinder with a nozzle between them, the device f is indoor cylinder and between the housing and the outer cylinder longitudinal septa, the width of which is made not less than the distance between the radial walls around the circumference of the corresponding cylinder, characterized in that the longitudinal walls forming an internal reservoir, equidistant offset walls forming external collectors, with mutual overlapping equal to the distance between the radial partitions on the circumference of the internal cylinder.
