Description

Technical Field

[0001] This utility model relates to the field of gas-solid separation technology, and more specifically, to a cyclone separator used for gas-solid separation in petroleum production. Background Technology

[0002] In oil production, cyclone separators are a crucial and widely used gas-solid separation device. Especially in fluidized catalytic cracking units, cyclone separators are indispensable key equipment. They utilize the principle of centrifugal force to efficiently and reliably separate solid particles such as catalyst powder, sand, coke powder, and salt crystals. Their core advantages are simple structure, no moving parts, convenient maintenance, large processing capacity, relatively low cost, and stable operation under harsh conditions such as high temperature and high pressure.

[0003] However, when using a cyclone separator for gas-solid separation, the solid particles will rub against the inner cavity of the cyclone separator under the action of centrifugal force. When the cyclone separator discharges the solid particles in a compressed state, the friction of the solid particles will cause the lower part of the cone of the cyclone separator to be worn.

A limiting plate 18 is installed at the bottom of the outer side of the cleaning plate 15.

[0035] Specifically, the working process or principle of the cyclone separator used for gas-solid separation in oil production is as follows: During use, the limiting ring 8 is placed on the support mechanism and moved upward to the separator housing 2. Then, the wear-resistant plates 6 are placed in the separator housing 2 in sequence, and the insertion blocks 7 on the wear-resistant plates 6 are inserted into the insertion slots 5 to install the wear-resistant plates 6. By moving the limiting ring 8 upward, the limiting ring 8 supports the wear-resistant plates 6, thereby tightening the support mechanism so that the support mechanism supports the wear-resistant plates 6 through the limiting ring 8. The wear-resistant plates 6 can improve the wear resistance of the easily worn areas inside the separator housing 2. After gas-solid separation, the cleaning plate 15 is inserted into the separator housing 2, and by pressing, the snap-fit ​​plate 13 is snapped onto the surface of the limiting ball 12. Then, by pushing the cleaning plate 15, the cleaning plate 15 rotates around the inner surface of the wear-resistant plates 6, thereby cleaning the solid particles on the inner surface of the wear-resistant plates 6.
