The invention relates to the processing of oil and gas and, in particular, to obtain granulated sulphur and can be used in several other industries to obtain dispersed materials.

Known installation to sing pipes, located on the swivel boom bucket wheel excavator for the development of the solidified sulfur, crusher, conveyors for feeding into the turret storage (silos).

The main significant disadvantages of the known technical solutions are: cycle time of obtaining sulphur (28 days); the impossibility of obtaining sulfur granules; significant investment and significant energy consumption.

The closest technical solution to the claimed is a device for obtaining granulated sulphur, for example, on Tarnobrzeska sulfur plant, consisting of two pipes, welded one to another in the form of an inverted letter T. In the installation of vertical pipe is constantly filled with grey 1 m, which creates the necessary hydrostatic pressure [1]

This technical solution chosen by the applicant as a prototype. It has some significant drawbacks, as the sprayed cooling liquid sulfur by supplying air from below the counter inside the silos, which leads to a significant increase in cost; the complexity of the operation due to the complicated regulatory process.

The aim of the invention is the implementation of the device in the form of a nozzle of cylindrical shape, inside there are three compartments separated by two walls and is equipped with nozzles: lower steam, medium to supply air to the air nozzle, the top output pair. The cameras are rigidly mounted spray sulfur and air nozzle and steam pipes for heating the sulfur sprays that are made in the form of tubes with blades fixed on the inner diameter of the nozzle at an angle of 45aboutto the axis of the tube, the outlet of which amounts to 0.8-0.9 of their internal diameter and the spray nozzle for sulfur attached to the top lid, and below its bottom, an air nozzle attached to the top wall of the lower chamber, down towards the bottom part of the device, and in the middle the camera mounted steam pipes for heating the sulfur sprays.

In addition, the objective is also achieved by the arrangement of the blades of the nozzles relative to each other at an angle of 90aboutand supply the upper housing flange for fastening to seropreva draught of the crane or for mounting in a silo.

From the patent and technical literature and experience of plant operations for sulfur is not aware of any similar tavsanoglu object is to run the body with sulfur spray and air nozzles and steam pipes for heating nozzles sulfur and ensuring injectors, made in the form of tubes, inside with blades fixed on the inner diameter of the tubes at 45aboutto its axis with the outlets of the tubes is equal to 0,8-0,9 their internal diameter, as well as in the original mount of all nozzles in the device. The above essential features collectively solve the purpose of the invention increase the reliability of the device if the quality of the obtained granulated sulphur. The device differs from all preceding low intensity. Thus, the legitimate conclusion about a causal connection between the new essential characteristics and effect that can be achieved from their implementation, and hence that the proposed solution meets the criterion of inventive step.

In Fig. 1 shows a device, a longitudinal section (a perspective view), and Fig. 2 shows the arrangement of the blades in the tubes of the nozzles in the context of Fig.3 blades injectors, turned 90aboutlocal incision around the axis of the tube.

The device consists of a casing 1 of cylindrical shape, the upper part of which is welded to the flange 2 for attachment of the device to the flange seropreva, on the other hand there is) to the bottom part of the device 5. The device is divided into 3 chambers.

The first lower chamber consists of a base bottom part of the device 5 and the partition 6, the middle chamber contains a partition wall 6 and the partition 7.

The third upper chamber is also divided by a partition 7 and the cover 8 devices. The lower chamber includes a spray nozzle for air 3 and 4 sulfur fixed to the bottom part of the device 5, the inlet air spray nozzles 3 are mounted rigidly in the partition 6, which is fixed and the inlet of the steam pipe 9 serving to heat the sulphur nozzles passing through the secondary chamber. The average camera includes partitions 6 and 7. The partition 6 are attached to the air inlet of the spray nozzle 3 and the input ends of the steam pipes 9 serving to heat the sulfur spray nozzle 4. The partition 7 are attached to the output ends of the steam pipes 9. The third upper chamber includes a partition wall 7 and the lid 8. The partition 7 are attached to the output ends of the steam pipes 9, and to the top cover 8 output ends of the sulfur spray nozzle 4 is pumped through the sulfur and which, passing secondary camera inside steam pipes are attached to the bottom part 5. Air and with hernych injectors for clarity in Fig.1 are shaded. Each camera has its own socket that is used to feed and output pair, designed for heating sulfur spray nozzle, and a pipe for air supply.

The nozzle 10 is designed to supply steam into the lower chamber 1, which is heated sulfuric nozzle 4, is fed to the inlet of the steam pipe 9 and heats the inside of the secondary chamber P. Passing steam pipes, steam enters the third upper chamber, where it is also heated sulfuric nozzle 4, exits through the outlet of the second upper chamber. The second secondary camera also has a socket 12 that is required to supply air to the inlet air spray nozzle 3.

In Fig. 2 shows the spray nozzle, which is identical for both the sulfur and air, with the only difference in length. Inside the spray tubes rigidly fixed blade 13, angled 45aboutto the axis of the tube and the 90aboutin relation to each other. The diameter of the outlet openings of the nozzles is 0.8-0.9 internal diameter of the tubes. Due to this creates a slight pressure behind the blades and the jet is smooth and has a cone shape, inside which creates a void due to the rotation of the stream.

The unit of work is the measure serves for heating the sulphur nozzles, and then, passing inside the steam pipe 9 enters the upper chamber, which also heats the sulfur jets leaving the nozzle 11 of the third upper chamber. After heating device to a temperature much more than the melting point of sulfur air is supplied to the second secondary chamber through the nozzle 12, where, passing air nozzle 3, the exit stream having a conical shape created by the blades of the nozzle. Then sulfur is fed through the flange 2 on sulfur spray tube 4, which passes them out of the jet device having the form of a cone generated by the blades of the nozzle. When this air pressure must be greater than 0.1-0.2 kg/cm2than the pressure of sulfur necessary to break up the stream of brimstone, where the formation of granules and their cooling stream of air at the same time. And when it exits it no longer pours and pours. After the operation, the device is turned off in the reverse order.

First off sulfur, then the air and only after you merge the remaining sulfur from the pipe and the device turns off steam. This is done in order to avoid solidification of the remaining sulfur spray to trusit increasing the number of tubes and the diameter of the device. This height can not be increased, increasing the number of nozzles for the supply of steam and air, with their diametrically around the device. Spray sulfur instead of air in this case can be used inert nitrogen gas to prevent explosions, fires and other accidents. In this case, the production of granulated sulphur and shipment can go at the same time, independently from each other in a continuous loop in silos.

Technical appraisal and economic benefits of the proposed device in comparison with the known are to a significant reduction in cost and simplification of manual labor required to produce the same amount of sulfur, the reduction of metal installations for the production of sulphur, as well as the time required for solidification of sulfur.
