Detailed description of the type drainage oil arrester:
1. Product introduction The type drainage oil arrester is a new patented product jointly developed by our company at the Nanchong Refinery Design Institute. This product replaces the water sealer in the oil tank area and has a compact structure. , small size, easy installation, high technical content, good automatic operation performance and low cost, it is currently the most ideal equipment for drainage and oil blocking in oil tank areas. Effectively prevent accidents caused by oil leakage, oil leakage, and oil leakage when the oil tank ruptures.
2. Working principle The drainage oil arrester is based on the principle of water density and buoyancy, and uses a flat floating body with a density between oil and water to open and close the circular hole to control the opening and closing of the drainage channel and the tank wall.
The operating status is as follows:
When the medium in the pipeline is all water or contains a very small amount of floating oil, the floating body is raised and the channel is open to discharge water.
. When the medium in the pipeline is all oil, the oil presses the water out of the buffer chamber downward. As the water in the buffer chamber decreases and the oil increases, the buoyancy force on the floating body becomes less and less. When the force on the floating body is less than When the floating body sinks due to the gravity of the floating body, the round hole will be blocked (i.e. closed) and the oil cannot flow out.
When the oil and water in the pipeline are mixed, the water inlet channel buffer chamber and the water channel form a water seal. Water is discharged from the bottom of the buffer chamber and the oil flows back from the upper part of the buffer chamber.
When there is no medium in the pipeline, since a certain water level is maintained in the device, the floating body in the device is in a constant floating state, so that the water in the oil tank area can be discharged normally at any time. Maintaining a certain water level in the buffer chamber is on the one hand to maintain the normal opening of the channel; on the other hand, it forms a water seal so that the front and rear valves of the drainage channel are separated by water to ensure regional safety.
3. Scope of application This product is suitable for drainage pipes in oil density/region. It can specifically meet the automatic discharge of rainwater and sewage in oil production equipment areas and oil storage tank areas. It does not require manual intervention and can automatically prevent tanks from abnormal conditions. Serious consequences caused by oil dispersion outside the area. Oil product name density Oil product name density Liquefied petroleum gas. Light diesel, medium fuel oil, civil fuel oil, crude oil. Gasoline, aviation gasoline. Heavy diesel, heavy fuel oil, normal pressure heavy oil, lubricating oil. Aviation kerosene. Less Pressure residue oil, residual fuel oil, kerosene.
4. Installation and maintenance
When the product is installed, it should be basically kept at the same level as the drainage pipe.
After installation, first use a flushing pipe to inject a certain amount of water into the valve to suspend the floating body before the valve can operate normally.
Regularly clean the sediment in the sedimentation well to ensure the normal operation of the valve.
Regularly use a flushing pipe to remove silt or sediment in the valve.
Regularly clean and inspect the floating body in the valve. Product specifications include: D, D, D, a total of three design pressures. The main material is carbon steel and the floating body is stainless steel. The flange standard is - The user can also specify the main body material or flange standard.
