Description

Technical Field

[0001] The utility model relates to the technical field of production water treatment in marine petrochemical industry, in particular to a cyclone head split type cyclone tube disassembly device. Background Art

[0002] A hydrocyclone is a gravity coalescer that uses centrifugal force to separate two-phase or multi-phase mixtures. It is a key device in the production waterway of offshore oil drilling platforms. The mixture in the hydrocyclone flows radially through hundreds of cyclone tubes inside the device, and the oil and water are separated under the action of centrifugal force. The cyclone tube is the core component of the hydrocyclone to complete the oil-water separation work.

[0003] In the water treatment process of offshore oil drilling platforms, the raw liquid entering the hydrocyclone contains a lot of suspended matter, sludge, grease and other pollutants. After a long period of production, the inside of the cyclone tube will form different degrees of scale, causing blockage of the flow channel in the tube. In this case, the fluid flow is restricted and the flow rate decreases, which in turn affects the centrifugal force and water pressure, hindering the oil-water separation process. When the water pressure is too low, a large number of flow stagnation areas will be generated in the hydrocyclone, causing the equipment to be unable to work effectively.

[0004] In order to ensure the daily production of the platform, offshore operators will regularly clean the cyclone tube inside the equipment. The cyclone tube currently used on the offshore platform is a cyclone head split cyclone tube. The cleaning process is as follows:

[0005] Step 1: Isolate the inlet and outlet valves of the hydrocyclone and confirm that the isolation is intact;

[0006] Step 2: Open the drain valve at the bottom of the hydrocyclone to depressurize and drain the equipment;

[0007] Step 3: Open the hydrocyclone cover, take out the cyclone tubes inside the equipment one by one, and use a high-pressure water gun to rinse the outer wall of the cyclone tube;

[0008] Step 4: Remove the swirl head of the swirl tube and use a high-pressure water gun to rinse the swirl head and the inner wall of the swirl tube;

[0009] Step 5: Reinstall the cleaned cyclone head onto the cyclone tube, and then reinstall them into the hydrocyclone in sequence until all cyclone tubes are reinstalled and the equipment is restored to operation.

[0010] In the fourth step of the above cleaning process, in order to clean the inside of the cyclone tube, the cyclone head needs to be disassembled, but this operation step has the following defects:

[0011] First, the disassembly of the swirl head is done by the operating staff with their bare hands. After a certain period of operation, scale and sludge will gradually accumulate in the flow channel groove connecting the swirl head and the inner tube wall in the swirl tube, which greatly increases the friction for disassembly of the swirl head. In addition, the outer wall of the swirl tube is slippery after flushing, making it difficult for the staff involved in the cleaning to disassemble it with their bare hands, and the work intensity is high.

[0012] Second, after workers have been working with their bare hands for a long time, the efficiency of disassembling a single cyclone tube will gradually decrease, causing the overall cleaning work to be delayed. The equipment will stop operating for an increased period of time, affecting the normal production of the platform. Utility Model Content
