[0003] Low separation efficiency: Traditional equipment is difficult to separate solid, liquid and gas mixtures simultaneously and efficiently, and often requires multi-stage processing;

[0004] The equipment is complex: existing three-phase separation devices have complex structures and are difficult to maintain;

[0005] Poor adaptability: Insufficient adaptability to materials under different working conditions (such as different particle sizes, concentrations, and viscosities);

[0006] High energy consumption: The separation process consumes a lot of energy, resulting in high operating costs;

[0007] Large footprint: Multi-stage separation systems require a large installation space;

[0008] Especially in fields such as produced fluid treatment in oil extraction, reaction product separation in chemical production, crystallization separation in pharmaceutical manufacturing, coal mine drainage treatment, and biomass pyrolysis gasification fuel tar purification, there is an urgent need for a high-efficiency, compact, and highly adaptable three-phase separation device.

[0009] Therefore, we propose a low-calorific-value gas cyclone three-phase separation and filtration device. Utility Model Content

[0010] The purpose of this invention is to provide a low-calorific-value gas cyclone three-phase separation and filtration device to solve the problem mentioned in the background art that existing three-phase separation and filtration devices are difficult to separate solid, liquid and gas mixtures simultaneously and efficiently, and often require multi-stage processing.

[0011] To achieve the above objectives, this utility model provides the following technical solution: a low-calorific-value gas cyclone.

[0012] A three-phase separation and filtration device includes an outer barrel with a tangential air inlet flange on its side wall, an outlet flange on the other side of the outer barrel, a top cover cap on the top of the outer barrel, a conical barrel at the bottom of the outer barrel, a support leg fixedly connected to one end of the outer barrel, a differential pressure sensor fixedly connected to the outer barrel, a level gauge fixedly connected to the bottom of the outer barrel, a liquid sensor fixedly connected to the side wall of the outer barrel, a partition baffle inside the outer barrel, a precision filter element inside the partition baffle, and a top cover plate fixedly connected to the precision filter element.

[0013] Preferably, the inlet flange is fixedly connected to the liquid sensor, the outlet end of the inlet flange is lower than the partition baffle, and the bottom surface of the inlet flange is provided with an inlet connection hole for connecting the differential pressure sensor air pipe.

[0014] Preferably, an outlet pressure sensor is fixedly connected to the top of the outlet flange, and an outlet connection hole for connecting the differential pressure sensor gas pipe is opened on the bottom surface of the outlet flange, with the inlet end of the outlet flange higher than the partition baffle.

[0015] Preferably, an automatic drain valve is fixedly connected to the outlet end of the cone barrel, and a level gauge is fixedly connected to the outlet end of the cone barrel.

[0016] Preferably, one end of the support leg is fixedly connected to the outer wall of the outer barrel, and the other end of the support leg is fixedly connected to the fixed base plate.

[0017] Preferably, the upper cover plate is fixedly connected to a screw rod, and both ends of the screw rod are provided with locking nuts.

[0018] Preferably, the liquid sensor is a liquid level sensor or an oil-water interface sensor, used to monitor the total liquid level or oil-water interface height in the cone.

[0019] Preferably, the upper cover plate has holes on its side wall, an air vent on its top, the air vent being connected to an outlet flange, and the bottom surface of the upper cover plate being a closed opening.

[0020] Preferably, the differential pressure sensor is fixedly connected to two air tubes, one end of which is connected to an inlet connection hole, and the other end of which is fixedly connected to an outlet connection hole.

[0021] Preferably, industrial waste gas containing dust, liquid, and possibly oil enters tangentially between the outer barrel and the partition baffle at high speed through the inlet flange, forming a downward external vortex;

[0022] Under the centrifugal force of the external vortex, solid particles and most of the liquid droplets are thrown toward the outer wall of the barrel, and then fall to the bottom of the cone to accumulate and stratify under the action of the vortex gravity.

[0023] After initial separation, the gas turns into an upward internal vortex at the bottom of the cone and rises in the annular channel between the separator baffle, the precision filter element, the top cover plate, and the cone.

[0029] Based on a preset program or sensor signal, the automatic drain valve opens to discharge the solid sludge deposited at the bottom of the cone.

[0030] Compared with the prior art, the beneficial effects of this utility model are:

[0031] 1. This utility model uses a vertical outer barrel to fix a partition baffle, which is fixedly connected to an upper cover plate. The upper cover plate is fixedly connected to a precision filter element, which is fixedly connected to the surface of the upper cover plate by a screw and a locking nut. The bottom surface of the upper cover plate is designed to be isolated, which ensures that the filter element can operate stably for a long time in liquid and oil-containing gases, greatly extending its service life. At the same time, it efficiently removes dust (including fine particles), water mist, and oil mist, providing high-quality gas for subsequent processes. A single device can achieve three-phase separation, with a small footprint and a simplified system.

[0032] 2. This utility model features an overflow port with a level gauge on the outer barrel, a liquid sensor on the outer barrel, and an automatic drain valve at the bottom of the cone, thereby achieving a high degree of automation (overflow + automatic slag discharge), long maintenance intervals (long filter life), and low energy consumption.

[0033] 3. This utility model uses a differential pressure sensor fixedly connected to the outer barrel body, and the differential pressure sensor is fixedly connected to 2...

[0034] Each tube has one end connected to the inlet connection hole and the other end fixedly connected to the outlet connection hole. This allows for effective determination of whether the precision filter element needs to be replaced based on the pressure difference, thereby improving the service life of the precision filter element and reducing the replacement cost.

[0041] Example

[0042] Please see Figures 1-4 The diagram illustrates a low-calorific-value gas cyclone three-phase separation and filtration device, comprising an outer barrel 3 with a tangential inlet flange 2 on its side wall, an outlet flange 8 on the other side of the outer barrel 3, a top cover 1 on the top of the outer barrel 3, a cone 5 below the outer barrel 3, a differential pressure sensor 14 fixedly connected to the outer barrel 3, one end of a support leg 12 fixedly connected to the outer barrel 3, a level gauge 13 fixedly connected to the bottom of the outer barrel 3, a liquid sensor 10 fixedly connected to the side wall of the outer barrel 3, a partition baffle 16 inside the outer barrel 3, a precision filter element 4 inside the partition baffle 16, and a top cover 17 fixedly connected to the precision filter element 4. The vertical outer barrel is fixedly connected to a partition baffle, which is in turn fixedly connected to a top cover plate. The top cover plate is then fixedly connected to a precision filter element. The precision filter element is secured to the surface of the top cover plate via screws and locking nuts. The bottom surface of the top cover plate is designed to isolate the filter element, ensuring its long-term stable operation in liquid and oil-containing gases, significantly extending its lifespan. Simultaneously, it efficiently removes dust (including fine particles), water mist, and oil mist, providing high-quality gas for subsequent processes. A single device achieves three-phase separation, occupies a small area, and simplifies the system. The circular tube baffle inside the outer barrel protects the user's rights regardless of its shape; it can be present even without the baffle, forming a protective mechanism.

[0043] Furthermore, the inlet flange 2 is fixedly connected to the liquid sensor 10, the outlet end of the inlet flange 2 is lower than the partition baffle 16, and the bottom surface of the inlet flange 2 is provided with an inlet connection hole for connecting the air pipe of the differential pressure sensor 14.

[0044] Furthermore, the outlet flange 8 is fixedly connected to the top of the outlet pressure sensor 7, and the bottom surface of the outlet flange 8 is provided with an outlet connection hole for connecting the gas pipe of the differential pressure sensor 14. The inlet end of the outlet flange 8 is higher than the partition baffle 16.

[0045] Furthermore, an automatic drain valve 6 is fixedly connected to the outlet end of the cone barrel 5, and a level gauge 13 is fixedly connected to one end of the outlet end of the cone barrel 5.

[0047] Furthermore, the differential pressure sensor 14 is fixedly connected to two air tubes 18. One end of one air tube 18 is connected to the inlet connection hole, and the other end of the air tube 18 is fixedly connected to the outlet connection hole. The two air tubes are connected through the differential pressure sensor. The two air tubes collect the airflow between the inlet flange and the outlet flange and enter the differential pressure sensor. The differential pressure can be used to determine whether the precision filter element needs to be replaced.

[0048] Furthermore, the upper cover plate 17 is fixedly connected to the screw rod 9, and both ends of the screw rod 9 are provided with locking nuts 11.

[0050] Furthermore, the upper cover plate 17 has holes on its side wall and an air vent on its top, which is connected to the outlet flange 8. The bottom surface of the upper cover plate 17 is a closed opening.

[0051] Furthermore, industrial waste gas containing dust, liquid, and possibly oil enters tangentially between the outer barrel 3 and the partition baffle 16 at high speed through the inlet flange 2, forming a downward external vortex.

[0052] Under the centrifugal force of the external vortex, solid particles and most of the liquid droplets are thrown toward the wall of the outer barrel 3, and slide down to the bottom of the cone barrel 5 to accumulate and stratify under the action of vortex gravity.

[0053] After initial separation, the gas turns into an upward internal vortex at the bottom of the cone 5 and rises in the annular channel between the separating baffle 16, the precision filter element 4, the upper cover plate 17, and the cone 5.

[0054] The rising gas reaches the bottom surface of the upper cover plate 17 and diffuses into the precision filter element 4;

[0055] The gas passes radially through the stainless steel pleated filter element 4 for fine filtration, removing residual fine particles and droplets;

[0056] Clean gas enters the central channel of the inner barrel 3 from the filter element 4;

[0057] The central passage is connected to the outlet flange 8;

[0058] When the total liquid level in cone 5 reaches the height of level gauge 13, the upper layer of liquid automatically overflows.

[0059] According to a preset program or sensor signal, the automatic drain valve 6 opens to discharge the solid sludge deposited at the bottom of the cone 5.

[0060] In this scheme, the workflow is as follows: when industrial waste gas containing dust, liquid, and possibly oil enters at high speed through the inlet flange 2 between the outer barrel 3 and the partition baffle 16, a downward external vortex is formed.

[0061] Under the centrifugal force of the external vortex, solid particles and most of the liquid droplets are thrown toward the wall of the outer barrel 3 and slide to the bottom of the cone barrel 5 to accumulate and stratify.

[0062] After initial separation, the gas turns into an upward internal vortex at the bottom of the cone 5 and rises in the annular channel between the separating baffle 16, the precision filter element 4, the upper cover plate 17, and the cone 5.

[0063] The rising gas reaches the bottom surface of the upper cover plate 17 and diffuses into the precision filter element 4;

[0064] The gas passes radially through the stainless steel pleated filter element 4 for fine filtration, removing residual fine particles and droplets;

[0065] Clean gas enters the central channel of the inner barrel 3 from the filter element 4;

[0066] The central passage is connected to the outlet flange 8;

[0067] When the total liquid level in cone 5 reaches the height of level gauge 13, the upper layer of liquid automatically overflows.

[0068] According to a preset program or sensor signal, the automatic drain valve 6 opens to discharge the solid sludge deposited at the bottom of the cone 5.
