Description

Technical Field

[0001] The utility model relates to the technical field of natural gas filtration, and particularly relates to a gas filtration and treatment device. Background Art

[0002] In the process of natural gas production, the produced natural gas generally accompanies water vapor and particulate impurities, and certain filtration treatment is required. At present, there are many technical solutions for setting up multiple-stage filter meshes on the gas production pipeline for filtration. However, the filtration efficiency of the existing multiple-stage filter meshes gradually decreases with the accumulation of the device usage time, and regular impurity cleaning is required, which affects the normal production and transportation of natural gas and the filtration effect is not good. Therefore, how to further improve the filtration effect of the filtration device has become the goal constantly pursued by those skilled in the art. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the technical problems in the prior art that the filtration effect of the multiple-stage filter mesh is not good and regular impurity cleaning is required, and to provide a gas filtration and treatment device.

[0004] The utility model provides a gas filtration and treatment device, including:

[0005] A cavity, the cavity includes an inlet and an outlet arranged oppositely;

[0006] A first filter plate, a second filter plate and a bottom plate, the bottom plate divides the space between the second filter plate and the inlet into a top chamber and a bottom chamber, and the first filter plate divides the top chamber into a first-stage chamber and a second-stage chamber that are horizontally communicated;

[0007] The bottom plate includes a first partition plate and a second partition plate. The side of the first partition plate close to the inlet is lower than the side connected to the first filter plate. The first partition plate is arranged opposite to the inlet. The side of the second partition plate connected to the first filter plate is lower than the side connected to the second filter plate;

[0008] A first communication port is arranged on the side of the first partition plate close to the inlet, and a second communication port is arranged on the side of the second partition plate close to the first filter plate.

[0009] A gas filtration and treatment device of the present utility model, one side of the first partition is connected to the side of the cavity near the inlet, the other side opposite to the first partition is connected to the first filter plate, the second partition is connected to the first filter plate and the second filter plate, and the side of the first partition near the inlet is lower than the side connected to the first filter plate, and the side of the second partition connected to the first filter plate is lower than the side connected to the second filter plate, that is, the first partition is inclined and the second filter plate is inclined, so that the cross-sectional areas of the primary chamber and the secondary chamber gradually decrease in the air flow direction. After the air flow accompanied by water vapor and impurity particles input from the inlet enters the primary chamber and / or the secondary chamber, the air flow velocity is changed, and the air flow climbs along the first partition and / or the second partition, and the water vapor and impurity particles therein slide down along the first partition and / or the second partition and enter the bottom chamber from the first communication port and / or the second communication port. At the same time, since the first partition is disposed opposite to the inlet, after part of the air flow impacts the first partition, the water vapor and impurity particles therein are blocked and slide down along the first partition under the action of gravity and enter the bottom chamber from the first communication port. At the same time, through the filtering function of the first filter plate, the air flow is further filtered and then enters the secondary chamber for further filtering. The impurities blocked in the secondary chamber enter the bottom chamber from the second communication port for collection. In addition, a small amount of the air flow entering the bottom chamber from the first communication port and the second communication port can push the impurities entering the bottom chamber to converge, and the air flow therein is then output from the part of the second filter plate located in the bottom chamber to improve the treatment effect; the filtering device with the multi-stage chamber structure divides, converges and filters the air flow on the basis of the structures of the primary chamber, the secondary chamber and the bottom chamber, and it is easy to form a turbulent flow, and the water vapor and impurity particles can partially settle before reaching the corresponding filter plate, which can reduce the filtering burden on the filter plate and improve the filtering effect.

[0010] Preferably, the first communication port is arranged lower than the inlet. That is, the connection position of the first partition on the side close to the inlet in the cavity is below the inlet, so that in the transverse direction of the air flow, the height of the first communication port is lower than that of the inlet, which can prevent the water vapor or impurity particles in the chamber from flowing back into the inlet.

[0011] Preferably, the second partition includes a conduction plate and a blocking plate, the conduction plate is horizontally arranged, the blocking plate is inclined, and the second communication port is arranged on the conduction plate. It is convenient for the arrangement of the second partition, and enables the impurities in the secondary chamber to enter the lower chamber from the second communication port and not easily impact the first filter plate again.

[0012] Preferably, a first aggregate tank is provided at the bottom of the bottom chamber, the first aggregate tank is provided with a first discharge port, and the first discharge port is externally connected to a pipeline and is provided with a first valve. So that the water vapor and impurities in the bottom chamber are output from the first discharge port to reduce the total amount of impurities in the filtering device.

[0013] Preferably, a first deflector plate and a second deflector plate are provided at the bottom of the bottom chamber. The first deflector plate and the second deflector plate are respectively inclined to form the first aggregate trough with a larger upper part and a smaller lower part. The first discharge port is arranged between the first deflector plate and the second deflector plate. This enables water vapor and impurities to gather at the bottom of the first aggregate trough, making it easy to collect and output them.

[0014] Preferably, a third filter plate is provided on one side of the second filter plate close to the outlet. A third-stage chamber is formed between the third filter plate and the second filter plate, and the third filter plate and the second filter plate are arranged in parallel. This is to further improve the filtering effect of the filtering device.

[0015] Preferably, a third partition plate is provided in the third-stage chamber. The third partition plate divides the third-stage chamber into an upper chamber and a lower chamber. The third partition plate is provided with a third communication port. The upper chamber is arranged opposite to the second-stage chamber, and the lower chamber is arranged opposite to the bottom chamber. That is, the connection heights of the third partition plate and the blocking plate on both sides of the second filter plate are the same. The air flow in the second-stage chamber enters the upper chamber after passing through the second filter plate, and the air flow in the bottom chamber enters the lower chamber after passing through the second filter plate. This is to further perform shunt and confluence processing on the air flow and improve the filtering effect.

[0016] Preferably, a second aggregate trough is provided at the bottom of the lower chamber. The second aggregate trough is provided with a second discharge port, and the second discharge port is externally connected to a pipeline and is provided with a second valve. This is to further collect and discharge water vapor and impurities.

[0017] Preferably, the part of the second filter plate below the second deflector plate is set as the first solid part, and the third filter plate is provided with a second solid part opposite to the first solid part. The height of the second solid part is greater than the height of the first solid part. This is to block the passage of impurities. Under the action of gravity, the impurities are stratified from the air flow and are not easily output through the third filter plate, further improving the filtering effect.

[0018] Preferably, the horizontal distance between the inlet and the first filter plate is greater than the horizontal distance between the first filter plate and the second filter plate; the horizontal distance between the first filter plate and the second filter plate is greater than the horizontal distance between the second filter plate and the third filter plate. This enables the air flow in a state with more water vapor and impurities to be better processed in the first-stage chamber, reduces the working pressure of the second filter plate and the third filter plate, and further improves the service life of each filter plate.

The airflow passing through is shunted, confluent and filtered and blocked by the first filter plate 2, the second filter plate 3 and the bottom plate arranged inside, so as to remove water vapor and impurities.

[0041] In an optional implementation manner, the cavity 1 can be cylindrical, cubic, etc., and can be set according to the actual situation.

[0042] In an optional implementation manner, the inlet 11 and the outlet 12 are located on opposite sides of the cavity 1, and the shapes of the inlet 11 and the outlet 12 are set according to the actual use situation.

[0044] The bottom plate divides the space between the second filter plate 3 and the inlet 11 into a top chamber 5 and a bottom chamber 6. The first filter plate 2 divides the top chamber 5 into a first-stage chamber 51 and a second-stage chamber 52 that are horizontally connected. The bottom plate includes a first partition plate 41 and a second partition plate 42. The side of the first partition plate 41 close to the inlet 11 is lower than the side connected to the first filter plate 2. The first partition plate 41 is disposed opposite to the inlet 11. The side of the second partition plate 42 connected to the first filter plate 2 is lower than the side connected to the second filter plate 3. A first communication port 43 is provided on the side of the first partition plate 41 close to the inlet 11, and a second communication port 44 is provided on the side of the second partition plate 42 close to the first filter plate 2.

[0045] In an optional embodiment, both the first filter plate 2 and the second filter plate 3 are mesh structural members, which can filter water vapor and impurities in the passing air flow. The first filter plate 2 is connected to the top of the bottom. In order to realize the connection with the second partition plate 42, the second filter plate 3 is provided with ribs at the middle position. Combining with the settings of the first communication port 43 and the second communication port 44, the diversion, confluence and filtration of the air flow in the top chamber 5 and the bottom chamber 6 are realized.

[0046] In an optional embodiment, the first communication port 43 is set lower than the inlet 11 and the distance between the first communication port 43 and the bottom of the inlet 11 exceeds 10 cm, which can effectively prevent water vapor or impurity particles from flowing back into the inlet 11.

[0047] In an optional embodiment, the second partition plate 42 includes a conduction plate 421 and a blocking plate 422. The conduction plate 421 is horizontally arranged, the blocking plate 422 is obliquely arranged, and the second communication port 44 is arranged on the conduction plate 421. This facilitates the setting of the second partition plate 42 and enables the impurities in the second-stage chamber 52 to enter the lower-stage chamber from the second communication port 44, and it is not easy to impact the first filter plate 2 again.

[0048] In an optional embodiment, the first communication port 43 and the second communication port 44 can be through-hole structures with any shape or arrangement state such as round holes and square holes.

A first discharge port 62 is provided at the position between the first guide plate 64 and the second guide plate 65 at the bottom of the first aggregate trough 61. The first discharge port 62 is externally connected to a pipeline and is provided with a first valve 63.

Then, the air flow is output from the secondary chamber 52 and the bottom chamber 6.

[0051] For a gas filtration and treatment device of this embodiment, during use, the air flow entering from the inlet 11 enters the primary chamber 51. Since the first partition 41 is inclined, the cross-sectional area of the primary chamber 51 gradually decreases in the air flow direction, changing the air flow velocity. The air flow climbs along the first partition 41, and the water vapor and impurity particles therein slide down along the first partition 41 and enter the bottom chamber 6 through the first communication port 43. At the same time, since the first partition 41 is disposed opposite to the inlet 11, after part of the air flow impacts the first partition 41, the water vapor and impurity particles therein are blocked and slide down along the first partition 41 under the action of gravity and enter the bottom chamber 6 through the first communication port 43. At the same time, through the filtering function of the first filter plate 2, the air flow is further filtered and then enters the secondary chamber 52 for further filtering. The impurities blocked in the secondary chamber 52 enter the bottom chamber 6 through the second communication port 44 for collection. In addition, a small amount of the air flow entering the bottom chamber 6 from the first communication port 43 and the second communication port 44 can push the impurities entering the bottom chamber 6 to gather, and the air flow therein is then output from the part of the second filter plate 3 located in the bottom chamber 6 to improve the treatment effect; for the filtration device with a multi-stage chamber structure, the air flow is shunted, converged, and filtered based on the structures of the primary chamber 51, the secondary chamber 52, and the bottom chamber 6, and it is easy to form a turbulent flow. The water vapor and impurity particles can partially settle before reaching the corresponding filter plates, which can reduce the filtering burden on the filter plates and improve the filtering effect.
