A separator

Abstract

This utility model relates to the field of separator technology and provides a separator with a shell. A conical settling hopper is detachably installed at the bottom of the shell. An inner cylinder is fixedly connected to the bottom of the inner cavity of the shell via a bracket. Support meshes are fixedly connected to the upper part and top of the inner cylinder's inner cavity, forming a primary filtration chamber between the two support meshes. Ceramic balls are embedded and filled within the primary filtration chamber. This separator, through its double-layer design, allows gas to flow upwards through the inner cavity of the inner cylinder, while separated liquid impurities flow downwards through the inner wall of the shell, facilitating the collection of liquid impurities. The downward-facing exhaust hopper on the inlet pipe aids in gas distribution and prevents filtered solid impurities from clogging the inlet pipe. The ceramic balls filling the primary filtration chamber prevent gas adsorption, thus avoiding interference with the raw material gas composition, and also help ensure uniform gas distribution. When solid impurities clog the gaps, several purge nozzles are used for purging.

Description

Technical Field

[0001] This utility model belongs to the field of separator technology, and in particular relates to a separator. Background Technology

[0002] During the oil and gas extraction and gathering process in oil fields, a large amount of hydrogen sulfide gas is generated in associated gas, natural gas and oil storage tanks. Hydrogen sulfide not only causes corrosion of equipment and pipelines and catalyst poisoning, affecting production safety, but also the escaped hydrogen sulfide gas poses a threat to human health and causes environmental pollution. Therefore, oil fields must remove hydrogen sulfide from associated gas.

[0003] In existing technologies, associated gas desulfurization technology in oilfields is mainly divided into two categories: wet desulfurization and dry desulfurization. Wet desulfurization is more widely used, but it has high requirements for the quality of the incoming gas and requires pretreatment of the gas to be treated. Impurities can easily affect the wet desulfurization agents, reduce their activity, and affect the quality of the desulfurization products. Impurities can also easily cause physical blockage in the desulfurization system. Therefore, in the wet desulfurization process, if the quality of the raw gas is poor, it is difficult to guarantee the activity of the desulfurization agents and reduce the desulfurization efficiency. Utility Model Content

[0004] This invention provides a separator designed to address the problem that poor quality of raw gas during wet desulfurization makes it difficult to ensure the activity of desulfurization agents and reduces desulfurization efficiency.

[0005] This utility model is implemented as follows: a separator includes a shell, a conical settling bucket is detachably provided at the bottom of the shell, an inner cylinder is fixedly connected to the bottom of the inner cavity of the shell by a bracket, and a support net is fixedly connected to the upper part and top of the inner cavity of the inner cylinder, forming a primary filtration chamber between the two support nets, and ceramic balls are embedded and filled in the primary filtration chamber.

[0006] An air inlet pipe is provided at the bottom of the side wall of the outer shell. The bottom end of the air inlet pipe extends to the bottom of the inner cavity of the inner cylinder and is connected to an exhaust hopper. A primary mist eliminator is fixedly connected to the upper part of the inner cavity of the outer shell, and a secondary mist eliminator is fixedly connected to the top of the inner cavity of the outer shell. An exhaust pipe is connected to the top of the outer shell. A spray structure for cleaning the surface of the ceramic ball is provided in the inner cavity of the outer shell.

[0007] Preferably, the bottom of the conical settling hopper is vertically connected to a drain pipe, a valve is installed on the drain pipe, and a level gauge is installed at the bottom of the side wall of the outer shell.

[0008] Preferably, the spray structure includes a purge disc and a purge pipe. The purge disc is disposed in the inner cavity of the outer shell and located above the inner cylinder. The purge pipe is disposed on the side wall of the outer shell and one end is connected to the purge disc. The lower surface of the purge disc is connected to a plurality of flexible hoses located above the inner cylinder, and the bottom end of the flexible hoses is connected to a purge nozzle.

[0009] Preferably, a manhole is provided on the upper part of the side wall of the outer shell, and a plurality of ladders are fixedly connected to the inner wall surface of the outer shell, and the plurality of ladders are evenly spaced along the height direction of the outer shell.

[0010] Preferably, a plurality of connecting seats are provided at the bottom of the side wall of the outer shell, and the plurality of connecting seats are evenly spaced in a ring along the surface of the outer shell. A threaded rod is rotatably connected inside the connecting seat, and a threaded sleeve is threadedly connected to the surface of the threaded rod. The side wall of the threaded sleeve is provided with a slot that matches the outer protruding edge of the side wall of the conical settling bucket, and a torsion handle is fixedly connected to the bottom end of the threaded sleeve.

[0011] Preferably, the top of the conical settling hopper is fixedly connected to an annular seal, and the bottom of the outer shell is provided with a sealing groove that matches the annular seal.

[0012] Preferably, both the primary fog eliminator and the secondary fog eliminator are inclined downwards along the inner cavity of the outer shell from one side to the other.

[0013] Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This separator, through its double-layer design, allows gas to flow upwards through the inner cavity of the inner cylinder, while the separated liquid impurities flow downwards through the inner wall of the outer shell, facilitating the collection of liquid impurities. Furthermore, the downward-facing exhaust hopper on the inlet pipe aids gas distribution and prevents filtered solid impurities from clogging the inlet pipe. Combined with a level gauge, it prevents untimely discharge when impurities in the incoming gas suddenly increase and accumulate excessively. The ceramic balls filling the primary filtration chamber do not adsorb gas, thus not affecting the composition of the raw gas, and also help to distribute the gas evenly. When solid impurities clog the gaps, several purge nozzles are used for purging. The nozzles are connected to the surface of the purging disc via flexible hoses. When purging begins, the nozzles rotate or sway irregularly. The clean water or gas distributed through several nozzles can be purged in more directions, increasing the purging area and improving purging efficiency. At the same time, the downward-facing nozzles can prevent clogging of the purging pipe. Both the primary and secondary mist eliminators are designed with an incline, which helps the deposited impurities to collect at the lower part and flow from the inner wall of the outer shell into the inner cavity of the conical settling hopper, preventing secondary pollution of the raw gas and achieving gas-liquid-solid three-phase separation. Impurities in the gas to be treated can be separated and removed at the front end, reducing the risk of reagent contamination and ensuring the activity or service life of the desulfurization reagent, thus protecting the desulfurization equipment.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a separator, including a shell 1, a conical settling hopper 2 detachably installed at the bottom of the shell 1, an inner cylinder 4 fixedly connected to the bottom of the inner cavity of the shell 1 by a bracket 3, a support net 5 fixedly connected to the upper part and top of the inner cavity of the inner cylinder 4, a primary filtration chamber 6 formed between the two support nets 5, and ceramic balls 7 embedded and filled in the primary filtration chamber 6.

[0023] An air inlet pipe 9 is provided at the bottom of the side wall of the outer shell 1. The bottom end of the air inlet pipe 9 extends to the bottom of the inner cavity of the inner cylinder 4 and is connected to the exhaust hopper 10. A primary mist eliminator 15 is fixedly connected to the upper part of the inner cavity of the outer shell 1. A secondary mist eliminator 16 is fixedly connected to the top of the inner cavity of the outer shell 1. An exhaust pipe 17 is connected to the top of the outer shell 1. A spray structure for cleaning the surface of the ceramic ball 7 is provided in the inner cavity of the outer shell 1. Both the primary mist eliminator 15 and the secondary mist eliminator 16 are inclined downwards from one side to the other side of the inner cavity of the outer shell 1.

[0024] The double-layer design allows gas to flow upward through the inner cavity of the inner cylinder 4, while the separated liquid impurities flow downward through the inner wall of the outer shell 1, which helps in the collection of liquid impurities. Furthermore, the gas flows downward through the exhaust hopper 10 on the intake pipe 9, which not only helps in gas distribution but also prevents the filtered solid impurities from clogging the intake pipe.

[0025] The primary filter chamber 6 is filled with ceramic balls 7, which will not adsorb gas and affect the composition of the raw material gas, and can also help the gas to be evenly distributed. When solid impurities clog the gaps, they are purged using several purge nozzles 14. The purging can be done with air or water depending on the actual situation. When the raw material gas contains combustible gas, inert gases such as nitrogen are used.

[0026] Both the primary mist eliminator 15 and the secondary mist eliminator 16 adopt an inclined design, which can help the deposited impurity phase to collect at the lower part and flow from the inner wall of the outer shell 1 into the inner cavity of the conical settling hopper 2, preventing secondary pollution of the raw gas and realizing gas-liquid-solid three-phase separation. Impurities in the gas to be treated can be separated and removed in the front section, reducing the risk of reagent pollution, ensuring the activity or service life of the desulfurization reagent, and protecting the desulfurization equipment.

[0027] Furthermore, the bottom of the conical settling hopper 2 is vertically connected to a drain pipe 20, and a valve 21 is installed on the drain pipe 20. A level gauge 18 is installed at the bottom of the side wall of the outer casing 1.

[0028] In this embodiment, the level gauge 18 prevents the gas from accumulating too much impurity suddenly and not being discharged in time. After opening the valve 21, the gas can be discharged through the drain pipe 20.

[0029] Furthermore, the spray structure includes a purge disc 12 and a purge pipe 11. The purge disc 12 is disposed in the inner cavity of the outer shell 1 and is located above the inner cylinder 4. The purge pipe 11 is disposed on the side wall of the outer shell 1 and one end is connected to the purge disc 12. The lower surface of the purge disc 12 is connected to several hoses 13 located above the inner cylinder 4. The bottom end of the hoses 13 is connected to a purge nozzle 14.

[0030] In this embodiment, several blowing nozzles 14 are connected to the surface of the blowing disk 12 via hoses 13. When blowing begins, the blowing nozzles 14 will rotate or shake irregularly. The clean water or gas distributed by the several blowing nozzles 14 can be blown in more directions, increasing the blowing area and improving the blowing efficiency. At the same time, the downward blowing nozzles 14 can also prevent the blowing pipe 11 from being blocked.

[0031] Furthermore, a manhole 19 is provided on the upper part of the side wall of the outer shell 1, and several ladders 8 are fixedly connected to the inner wall surface of the outer shell 1. The multiple ladders 8 are evenly spaced and distributed along the height direction of the outer shell 1.

[0032] In this embodiment, the manhole 19 facilitates access to the interior of the outer casing 1 for maintenance. The number of manholes 19 can be set according to the height of the separator. When the separator is high, multiple manholes 19 can be provided for convenient operation. The ladder 8 can also be provided on both the inner wall and the outer surface of the outer casing 1.

[0033] Furthermore, a number of connecting seats 22 are provided at the bottom of the side wall of the outer shell 1. The multiple connecting seats 22 are evenly distributed in a ring along the surface of the outer shell 1. A threaded rod 23 is rotatably connected inside the connecting seat 22. A threaded sleeve 24 is threadedly connected to the surface of the threaded rod 23. The side wall of the threaded sleeve 24 is provided with a bayonet 25 that matches the outer protruding edge of the side wall of the conical settling bucket 2. A torsion handle 26 is fixedly connected to the bottom end of the threaded sleeve 24.

[0034] In this embodiment, turning the handle 26 moves the threaded rod 23, which then engages with the outer protruding edge of the conical settling hopper 2 through the latch 25, thereby locking and fixing the outer shell 1 and the conical settling hopper 2.

[0035] Furthermore, the top of the conical settling hopper 2 is fixedly connected with an annular seal, and the bottom of the outer shell 1 is provided with a sealing groove that matches the annular seal.

[0036] In this embodiment, after the outer shell 1 and the conical settling hopper 2 are connected and fixed, the annular seal is embedded in the sealing groove to seal the space between the outer shell 1 and the conical settling hopper 2.

[0037] The working principle and usage process of this utility model are as follows: After installation, the raw material gas containing impurities enters the separator inner cylinder 4 through the inlet pipe 9 and the exhaust hopper 10. When the gas passes through the primary filter chamber 6 containing ceramic balls 7, most of the solid particles are filtered out by the ceramic balls 7. Some oil and water droplets condense when the raw material gas cools down, thus achieving preliminary filtration of the original gas. Impurities flow along the inner wall of the inner cylinder 4 into the conical settling hopper 2. Some impurities remaining in the ceramic balls 7 can be periodically cleaned by blowing through the blow-off nozzle 14. The raw material gas after preliminary filtration continues to rise, and the liquid droplets carried by the gas encounter the inclined first-stage mist eliminator 15 and the second-stage mist eliminator 16. Most of the liquid droplets collect in the first stage. After passing through the primary mist eliminator 15 and the secondary mist eliminator 16, which are designed with an incline, most droplets will flow to the lower part and then deposit downwards along the inner wall of the outer shell 1, eventually settling in the conical settling hopper 2. Regular discharge is performed daily, or via the level gauge 18. When the level gauge 18 shows a reading, it indicates that a certain amount of impurities have settled at the bottom, which can be discharged by opening the valve 21 and using the drain pipe 20. After three stages of filtration, most solid impurities and condensable liquid impurities have been separated, and the gas continues to rise to the next process. When maintenance or repair is needed inside the equipment, the interior of the outer shell 1 can be accessed through the ladder 8 and manhole 19.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
