[0018] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Please see Figure 1 and Figure 2 The gas-solid separation device system 100 of this utility model includes a gravity settling chamber 1, a cyclone collector 2, a high-precision dust collector 3, a drive device 4, and several connecting pipes 5. The gravity settling chamber 1, the cyclone collector 2, the high-precision dust collector 3, and the drive device 4 are connected sequentially through the connecting pipes 5 along the airflow direction. The drive device 4 is used to drive the dust-laden gas to pass sequentially through the gravity settling chamber 1, the cyclone collector 2, and the high-precision dust collector 3 and discharge clean gas. The interior of the gravity settling chamber 1 is provided with a turbulence structure 11 for gravity settling of coarse dust particles in the dust-laden gas to separate the coarse dust particles. The cyclone collector 2 is used to make the dust-laden gas entering it rotate at high speed to separate the medium-sized dust particles in the dust-laden gas using centrifugal force. The interior of the high-precision dust collector 3 is provided with a filter element structure 31 for filtering the dust-laden gas. The filter element structure 31 is a high-temperature ceramic membrane filter element or a titanium rod sintered filter element for filtering fine dust particles in the dust-laden gas.

[0020] The gas-solid separation system 100 of this invention uses a drive device 4 to drive dust-laden gas through a gravity settling chamber 1, a cyclone collector 2, and a high-precision dust collector 3. In the gravity settling chamber 1, a turbulence structure 11 separates coarse dust particles. In the cyclone collector 2, centrifugal force separates medium-sized dust particles. In the high-precision dust collector 3, a high-temperature ceramic membrane filter or a sintered titanium rod filter filters fine dust particles, achieving continuous and efficient graded separation of dust particles with a wide range of particle sizes in the gas. Simultaneously, the high-temperature ceramic membrane filter and the sintered titanium rod filter can withstand high-temperature environments and achieve a filtration accuracy of up to 1 micrometer, providing a final guarantee for the discharge of clean gas and meeting the needs of special operating conditions.

[0021] Please see Figure 1 In one embodiment, the gravity settling chamber 1 has a gravity settling space 12 inside, and a turbulence structure 11 is disposed within the gravity settling space 12. The bottom of the gravity settling chamber 1 has a settling chamber inlet 13 communicating with the gravity settling space 12, allowing dust-laden gas to enter the gravity settling space 12. The upper part of the gravity settling chamber 1 has a settling chamber outlet 14 communicating with the gravity settling space 12, and a connecting pipe 5 connects the settling chamber outlet 14 to the cyclone collector 2. The dust-laden gas enters from the bottom of the gravity settling chamber 1 and flows upwards, passing through the turbulence structure 11. Coarse dust particles settle and separate under the action of gravity and turbulence. Then, the gas exits from the upper settling chamber outlet 14 and enters the cyclone collector 2, improving the separation effect of coarse dust particles.

[0022] In one embodiment, the particle size of the coarse dust particles is greater than 50 micrometers. The gravity settling chamber 1 can separate dust particles larger than 50 micrometers in the dust-laden gas by settling, but is not limited to this.

[0023] Specifically, the turbulence structure 11 includes several turbulence plates 111, which are alternately arranged from bottom to top on opposite inner sidewalls of the gravity settling chamber 1. The turbulence plates 111 are arranged at an angle to form a tortuous turbulence channel 112 for the dust-laden gas to pass through within the gravity settling space 12. The several alternately inclined turbulence plates 111 form a tortuous turbulence channel 112. As the dust-laden gas flows within the tortuous turbulence channel 112, it continuously changes direction, increasing the residence time of the gas in the gravity settling chamber 1. At the same time, it makes it easier for coarse dust particles to collide with the turbulence plates 111 and settle under gravity, further improving the separation efficiency of coarse dust particles.

[0024] Furthermore, the baffle 111 is inclined downwards from its position connected to the inner wall of the gravity settling chamber 1 towards the center of the gravity settling space 12. This inclined arrangement of the baffle 111 can better guide coarse dust particles to settle towards the bottom of the gravity settling chamber 1, preventing dust particles from accumulating on the baffle 111 and ensuring the unobstructed flow of the tortuous baffle channel 112.

[0025] Please see Figure 1 In one embodiment, the gas-solid separation device system 100 further includes a coarse powder discharge valve device 6. The bottom of the gravity settling chamber 1 is provided with a coarse powder outlet 15, which communicates with the gravity settling space 12 and is located below the settling chamber inlet 13. The coarse powder outlet 15 is used to discharge coarse dust particles. The coarse powder discharge valve device 6 is located at the bottom of the gravity settling chamber 1 and is used to open or close the coarse powder outlet 15. By providing the coarse powder discharge valve device 6 and the coarse powder outlet 15, it is convenient to periodically discharge the coarse dust particles separated from the gravity settling chamber 1, facilitating dust recycling or treatment, while preventing dust accumulation from affecting the normal operation of the gravity settling chamber 1.

[0026] Please see Figure 1 In one embodiment, the cyclone collector 2 has a cyclone collection space 21 inside. The side wall of the cyclone collector 2 is provided with a cyclone collection inlet 22 for allowing dust-laden gas to enter the cyclone collection space 21 tangentially. The top of the cyclone collector 2 is provided with a cyclone collection outlet 23 for discharging the dust-laden gas. The gravity settling chamber 1 is connected to the cyclone collection inlet 22, and the cyclone collection outlet 23 is connected to the high-precision dust collector 3 through connecting pipes 5. Specifically, the settling chamber outlet 14 of the gravity settling chamber 1 is connected to the cyclone collection inlet 22 through the connecting pipe 5.

[0027] Dust-laden gas enters tangentially from the side wall of the cyclone collector 2, forming a high-speed rotating airflow within the cyclone collection space 21. Under the action of centrifugal force, medium-sized dust particles are thrown against the inner wall of the cyclone collector 2 and settle. Then, the gas is discharged from the top cyclone collection outlet 23, improving the separation effect of medium-sized dust particles.

[0028] In one embodiment, the particle size of medium-sized dust particles is in the range of 10 micrometers to 50 micrometers. The cyclone collector 2 can separate dust particles in the range of 10 micrometers to 50 micrometers in the dust-laden gas, but is not limited to this.

[0029] Please see Figure 1In one embodiment, the gas-solid separation device system 100 further includes a medium-powder discharge valve device 7. The bottom of the cyclone collector 2 is provided with a medium-powder outlet 24 communicating with the cyclone collection space 21. The medium-powder outlet 24 is used to discharge medium-sized dust particles. The medium-powder discharge valve device 7 is located at the bottom of the cyclone collector 2 and is used to open or close the medium-powder outlet 24. By providing the medium-powder discharge valve device 7 and the medium-powder outlet 24, it is convenient to periodically discharge the medium-sized dust particles separated from the cyclone collector 2, facilitating their processing or recycling and ensuring the continuous and stable operation of the cyclone collector 2.

[0030] Furthermore, the bottom of the cyclone collector 2 is provided with a cyclone collection storage chamber 25 for temporarily storing dust particles, and the medium powder outlet 24 is formed at the bottom of the cyclone collection storage chamber 25, but is not limited thereto.

[0031] Please see Figure 1 and Figure 2 In one embodiment, the high-precision dust collector 3 has a high-precision dust collection space 32 inside. A high-precision dust collection inlet 33 communicating with the high-precision dust collection space 32 is provided on the middle side wall of the high-precision dust collector 3. A high-precision dust collection outlet 34 communicating with the high-precision dust collection space 32 is provided at the top of the high-precision dust collector 3. The cyclone collector 2 is connected to the high-precision dust collection inlet 33, and the high-precision dust collection outlet 34 is connected to the drive device 4 via connecting pipes 5. A filter element structure 31 is disposed within the high-precision dust collection space 32, located above the high-precision dust collection inlet 33 and below the high-precision dust collection outlet 34. Dust-laden gas entering the high-precision dust collection space 32 from the high-precision dust collection inlet 33 is filtered by the filter element structure 31 and discharged from the high-precision dust collection outlet 34. Specifically, the cyclone collection outlet 23 of the cyclone collector 2 is connected to the high-precision dust collection inlet 33 via connecting pipes 5.

[0032] Dust-laden gas enters from the middle of the high-precision dust collector 3, flows upward through the filter element structure 31, and fine dust particles are trapped by the filter element structure 31. Clean gas is discharged from the upper outlet. This structural design helps to improve filtration efficiency and ensure filtration effect.

[0033] In one embodiment, the particle size of the fine dust particles ranges from 1 micrometer to 10 micrometers. Since the filter element structure 31 adopts a high-temperature ceramic membrane filter element or a titanium rod sintered filter element, dust particles in the dust-laden gas range of 1 micrometer to 10 micrometers can be separated, but this is not a limitation. For example, the filtration accuracy of the high-temperature ceramic membrane filter element can reach 0.1µm or even lower.

[0034] Furthermore, the gas-solid separation device system 100 also includes an inert gas backflushing device 35. The inert gas backflushing device 35 is mounted on the high-precision dust collector 3 and inserted into the high-precision dust collection space 32, positioned above the filter element structure 31. The inert gas backflushing device 35 blows inert gas onto the filter element structure 31 to sweep away dust within the filter element structure 31 and suppress the oxygen content in the high-precision dust collection space 32. The inert gas backflushing device 35 can periodically backflush the filter element structure 31, removing dust trapped on the filter element, including filtered dust particles, preventing clogging of the filter element structure 31, and extending its service life. Simultaneously, the introduction of inert gas suppresses the oxygen content within the high-precision dust collection space 32, preventing safety accidents under easily oxidizing conditions.

[0035] Please see Figure 2 In one embodiment, the gas-solid separation device system 100 further includes a fine powder discharge valve device 8. The bottom of the high-precision dust collector 3 is provided with a fine powder outlet 36 communicating with the high-precision dust collection space 32. The fine powder outlet 36 is used to discharge fine dust particles. The fine powder discharge valve device 8 is located at the bottom of the high-precision dust collector 3 and is used to open or close the fine powder outlet 36. By setting the fine powder discharge valve device 8 and the fine powder outlet 36, it is convenient to periodically discharge the fine dust particles filtered out of the high-precision dust collector 3, which is convenient for processing or recycling and ensures the normal operation of the high-precision dust collector 3.

[0036] Please see Figure 1 In one embodiment, the driving device 4 is a high-temperature fan, and the driving device 4 is respectively provided with a driving port 41 and an outlet 42. The connecting pipe 5 connects the high-precision dust collector 3 and the driving port 41, and the outlet 42 is used to discharge clean gas. However, this is not a limitation. Specifically, the connecting pipe 5 connects the high-precision dust collection outlet 34 and the driving port 41.

[0037] Combination Figure 1 and Figure 2 The specific working principle of the gas-solid separation device system 100 of this utility model is as follows:

[0038] Driven by the drive device 4, the high-temperature dust-laden gas sequentially enters the gravity settling chamber 1, the cyclone collector 2, and the high-precision dust collector 3. The gas enters from the bottom of the gravity settling chamber 1 and flows upwards, passing through the turbulence structure 11. Coarse dust particles settle and separate under the influence of gravity and turbulence. The gas then exits from the upper settling chamber outlet 14 and enters the cyclone collection inlet 22 of the cyclone collector 2. From there, it tangentially enters the cyclone collection space 21 through the cyclone collection inlet 22 from the side wall of the cyclone collector 2. Within the cyclone collection space 21, a high-speed rotating airflow is formed. Under the action of centrifugal force, medium-sized dust particles are thrown against the inner wall of the cyclone collector 2 and settle. The gas is then discharged from the top cyclone collection outlet 23. Subsequently, the gas enters the high-precision dust collection space 32 through the high-precision dust collection inlet 33 of the high-precision dust collector 3, and then flows upward through the filter element structure 31. Fine-sized dust particles are trapped by the filter element structure 31, and the clean gas is discharged from the upper outlet, and finally discharged from the exhaust outlet 42 of the drive device 4. The discharged gas can be returned to the system or preheated for reuse. Specifically, the coarse powder outlet 15 can be opened by the coarse powder discharge valve device 6 to discharge the coarse dust particles separated in the gravity settling chamber 1, facilitating dust recycling or treatment; the medium powder outlet 24 can be opened by the medium powder discharge valve device 7 to discharge the medium dust particles separated in the cyclone collector 2, facilitating their treatment or recycling; and the fine powder outlet 36 can be opened by the fine powder discharge valve device 8 to discharge the fine dust particles filtered out in the high-precision dust collector 3, facilitating their treatment or recycling.

[0039] In summary, this utility model, by setting up a gravity settling chamber 1, a cyclone collector 2, and a high-precision dust collector 3, sequentially separates coarse, medium, and fine dust particles. It combines multiple separation methods, including gravity settling, centrifugal separation, and filter cartridge filtration, to efficiently handle dust-laden gas with high-temperature, wide-range particle size distribution, improving gas-solid separation efficiency and thus increasing the yield of finished products in new energy production. Specifically, the turbulence structure 11 in the gravity settling chamber 1 prolongs the residence time of the dust-laden gas within it, allowing coarse dust particles to settle more fully and improving the separation effect. The cyclone collector 2 utilizes centrifugal force to separate medium-sized dust particles, offering high separation efficiency, a simple structure, and stable operation. The filter cartridge structure 31 of the high-precision dust collector 3 uses a high-temperature ceramic membrane filter or a sintered titanium rod filter, effectively filtering fine dust particles and exhibiting good high-temperature resistance, making it suitable for long-term use in the high-temperature environment of new energy production.

[0040] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
