Description

Technical Field

[0001] The utility model relates to the technical field of cyclone separators, in particular to a cyclone separator for gas processing. Background Art

[0002] The working principle of the cyclone separator is based on the action of centrifugal force. The centrifugal force generated by the rotation of the cyclone is used to separate the high-speed flowing material into different components. When the fluid passes through the cyclone, it enters along the direction of the cyclone pipe and rotates at high speed in the pipe to form a vortex. When the vortex flows, the solid particles in the fluid tend to settle outward due to their inertia and form a solid particle layer in the separation chamber, while the liquid flows in the inner layer and is discharged through the liquid outlet. In the process of active catalyst production, it is necessary to use it to separate the catalyst from the gas. When the existing cyclone separator is in use, after the airflow containing catalyst particles is discharged from the bottom of the cyclone separator, the airflow needs to be filtered to intercept and separate the catalyst particles in the airflow. The existing interception method is mainly to install a filter at the outlet. After the catalyst intercepted by the filter meets the requirements, the filter needs to be replaced in time. When replacing the filter, the cyclone separator needs to be stopped to avoid waste of catalyst during the replacement process, which is inefficient. Utility Model Content

[0003] The utility model aims to solve the shortcomings of the prior art that the cyclone separator needs to be stopped to avoid waste of catalyst during replacement and low efficiency, and proposes a cyclone separator for gas treatment.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1: Reference Figure 1-7 A cyclone separator for gas processing includes a separator body 1, a filter barrel 2 is provided below the separator body 1, the filter barrel 2 is cylindrical, a partition plate 5 is coaxially mounted in the filter barrel 2, the partition plate 5 is arc-shaped, and two baffle plates 3 are provided on the outer surface of the partition plate 5 along the circumference thereof, which fit the filter barrel 2. The baffle plates 3 are arc-shaped and symmetrically arranged. The baffle plates 3 are fixedly connected to the inner wall of the filter barrel 2. The outer surfaces of the two baffle plates 3 are fixedly connected to the inner wall of the filter barrel 2 via a fixing plate 4. A group of air outlet pipes 11 are respectively provided through the bottom of the filter barrel 2 on both sides of the fixing plate 4. An air inlet pipe 10 is provided on the top of the filter barrel 2 corresponding to the partition plate 5, and the air inlet pipe 10 is connected to the bottom outlet of the separator body 1. The air inlet pipe 10 is conical, and the conical air inlet pipe 10 can reduce the air flow velocity while expanding its coverage.

[0022] A conical guide body 7 is coaxially fixed in the partition plate 5. The conical guide body 7 can guide the incoming gas to all sides to avoid the gas directly impacting the bottom surface and being bounced back.

[0023] A drive shaft 8 is coaxially mounted on the bottom of the filter barrel 2 , the drive shaft 8 is fixedly connected to the partition plate 5 , and the drive shaft 8 is transmission-connected to a driver 9 .

[0024] A plurality of vertical sealing strips 6 are circumferentially fixed to the outer surface of the partition plate 5. The vertical sealing strips 6 have an arcuate cross-section and are provided to improve the sealing between the partition plate 5 and the baffle plate 3. The arcuate cross-section also significantly reduces friction between the vertical sealing strips 6 and the baffle plate 3, ensuring smooth rotation of the partition plate 5 while maintaining a tight seal.

[0025] Example 2: Reference Figure 1-5Another preferred embodiment of the present invention differs from Example 1 in that two collection boxes 12 are provided at the bottom of the filter barrel 2. These two collection boxes 12 correspond to the two sets of outlet pipes 11, and the corresponding outlet pipes 11 extend into their respective collection boxes 12. Each collection box 12 is equipped with a hatch 14 and an exhaust pipe 13, which is connected to a gas purification device. By providing two collection boxes 12, if the gas contains harmful components, the harmful gases passing through the filter bags on the outlet pipes 11 can be collected and directed to the gas purification device through the exhaust pipe 13, thereby achieving treatment of the harmful gases. The collection boxes 12 can also be equipped with a circulation pipe, which is connected to the gas purification device outlet. This allows the harmful gases in the collection boxes 12 to be purified into harmless gases by the gas purification device and then returned to the device, achieving rapid purification of the gas in the collection boxes 12. The hatch 14 is equipped with a glass window. The glass window can be used to see the collection conditions of the filter bags on the outlet pipes 11.

[0026] When the present invention is in use, a filter bag is put on the end of the air outlet pipe 11 and tied and fixed. In this way, after the gas containing the catalyst enters the filter barrel 2 through the air inlet pipe 10, the partition plate 5, the blocking plate 3, and the fixing plate 4 in the filter barrel 2 divide the inner cavity of the filter barrel 2 into two parts, so that the gas can only be discharged through a separate set of air outlet pipes 11 at the bottom of the filter barrel 2. At this time, the filter bag will intercept the catalyst in the gas. When the catalyst intercepted by the filter bag on this set of air outlet pipes 11 meets the requirement, the operator starts the driver 9, so that the driver 9 drives the drive shaft 8 to rotate, and the drive shaft 8 drives the partition plate 5 to rotate until the partition plate 5 rotates to the other side. In this way, the gas can only be discharged through the other set of air outlet pipes 11. In this way, the operator can replace the filter bag on the previous set of air outlet pipes 11 without stopping the cyclone separator, and the operation is more efficient.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
