Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for filter screen production, in particular to a drying device for oil-gas separator filter screen production. Background Art

[0002] An oil-gas separator is a device that separates crude oil and associated natural gas produced from an oil well. During this process, centripetal force typically causes the crude oil to form droplets of varying diameters. Therefore, a filter is required within the oil-gas separator to filter droplets smaller than 0.1 μm in diameter. Existing filters installed in oil-gas separators typically have pores for water vapor to escape during drying. However, this water vapor carries a significant amount of heat, resulting in energy loss and a waste of resources.

[0003] A search revealed, for example, (Authorization Announcement No. CN220892822U) a drying device for producing oil-gas separator filters, comprising a drying barrel with a base fixedly mounted at the lower end, a vent opening on the outside of the barrel, and a control box fixedly mounted on the outside of the barrel. This drying device for producing oil-gas separator filters uses a second motor and a driving gear to drive a sleeve and a placement rack at the upper end of a driven wheel to rotate, causing the driven gear and the oil-gas separator filter on the placement rack to rotate along with the sleeve, evenly distributing heat across the four filters, ensuring that each part is dried to the same degree. This device addresses the problem of existing equipment being unable to remove water vapor, thereby improving drying efficiency. However, the device cannot recycle the heat contained in the water vapor, resulting in significant overall energy loss and reduced economic efficiency. Utility Model Content

[0030] Example

[0031] like Figures 1 to 4 As shown,

[0032] This embodiment includes:

[0033] A drying barrel 4 is installed in the oil-gas separator to dry the filter screen. An annular heating ring 2 is fixed to the side wall of the drying barrel 4. An electric heating wire is provided inside the heating ring 2. The air inside the hollow heating ring 2 is heated by the electric heating wire. When the filter screen is dried inside the drying barrel 4, the air overflowing from the drying barrel 4 carries a large amount of heat and moisture. At this time, the heating ring 2 can not only further separate the moisture carried, but also heat the air carrying heat, which is convenient for the circulation of air.

[0034] The filter ring 5 is used for dehydration and deodorization. The middle of the filter ring 5 is hollowed out and filled with activated carbon. Because the activated carbon has a large specific surface area, it is not only suitable for removing water vapor in the air, but also can absorb the odor carried by the filter mesh used in the oil and gas separator, avoiding the odor carried by the filter mesh caused by drying the filter mesh to pollute the surrounding air. You can also choose a suitable medium according to actual conditions to clean the odor carried in the recycled air. In order to ensure the practicality of the activated carbon, the filling medium inside the filter ring 5 is regularly dried, cleaned and replaced to ensure the actual effect of the filter ring 5.

[0035] Two staggered connecting tubes 14 are provided on the top of the filter ring 5. The side walls of the two connecting tubes 14 are slidably connected to the sockets. The bottom of the heating ring 2 is also provided with a socket for easy connection. By pulling the connecting tubes 14 and the sockets, the heating ring 2 and the filter ring 5 can be connected, which not only heats the air inside the drying barrel 4, but also dehumidifies and removes odors simultaneously, making it easy to use.

[0036] Multiple fixing ears 15 are provided for easy connection. The side walls of the fixing ears 15 are welded to the side walls of the filter ring 5. The fixing ears 15 are also connected and fixed by provided bolts 16. The inner wall of the filter ring 5 abuts the side wall of the drying barrel 4 because the side walls of the fixing ears 15 are welded to the side walls of the filter ring 5. A mounting hole for easy connection is provided on one side of the fixing ear 15, and a threaded hole is provided on the other side of the fixing ear 15. The two fixing ears 15 are connected and fixed by the provided bolts 16 passing through the threaded holes inside the mounting holes, so that the two semicircular filter rings 5 ​​are connected to the drying barrel 4. The provided connecting pipes and pipelines are used to connect the filter ring 5 to the drying barrel 4, which is convenient for the circulation of hot air.

[0037] A bottom plate 3 is connected to the bottom of the drying barrel 4, and a support leg is welded to the bottom of the bottom plate 3 for support. A cover plate 1 is hingedly connected to the top of the drying barrel 4 by a hinge 6. A lock is provided on the other side of the cover plate 1 for fixing to the drying barrel 4. A circulation pump 8 is welded to the top of the cover plate 1. The working pipe of the circulation pump 8 passes through the cover plate 1 and extends into the interior of the drying barrel 4. Two bellows 7 are connected to the output end of the circulation pump 8 to facilitate the movement when the cover plate 1 is folded. The other end of the bellows 7 is connected to the heating ring 2.

[0038] A column 9 is fixed on the inner wall of the drying barrel 4. The column 9 is hollow, and a heating column 13 is provided in the middle of the column 9. A number of evenly spaced through holes 11 are provided on the circumference of the column 9. A fan is embedded in the bottom of the drying barrel 4, and the output end of the fan is connected to the groove 12. The groove 12 is provided on the inner bottom wall of the column 9, so that under the action of the fan and the through hole 11, the hot air is blown out evenly. Four symmetrical fixing rods 10 connected to the inner bottom wall of the drying barrel 4 are also provided on the circumference of the column 9. A heating structure similar to a heating resistance wire is provided inside the fixing rod 10. Through the joint action of the fixing rod 10 and the heating column 13, the oil and gas separator filter inside the drying barrel 4 is dried, which is convenient for use.

[0039] The heating ring 2, fan, circulation pump 8 and heating column 13 are all conventional instruments. Their working principles, sizes and models are irrelevant to the functions of this application, so they will not be described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0040] How it works

[0041] When using this drying device for producing oil-gas separator filters, the cover 1 is opened by means of a lock and hinge 6, the filter to be processed is placed inside the drying barrel 4, and the heating device inside the heating column 13 and the fixing rod 10 is started, causing the temperature inside the drying barrel 4 to rise rapidly. At this time, the circulation pump 8 is controlled to rotate, and the air inside the drying barrel 4 is extracted and input into the heating ring 2 through the connected bellows 7. The heating ring 2 heats the air containing water vapor and the residual temperature, and then passes through the connected jack and connecting pipe 14 through the filter ring 5 fixed to the side wall of the drying barrel 4 to complete the dehumidification and deodorization of the air.

[0042] Then, the air inside the drying barrel 4 is circulated through the channel connecting the filter ring 5 and the drying barrel 4, thereby completing the drying of the filter screen.
