Description

Technical Field

[0001] The invention relates to the technical field of oil and gas exploitation, and in particular to an oil and gas separator. Background Art

[0002] Oil and gas refers to the gas that comes out of oil wells along with petroleum, and its main components are methane, ethane, etc. It is used as fuel and chemical raw materials.

[0003] When using the above technology, it was found that the following technical problems exist in the prior art: when using an oil-gas separator to separate crude oil and associated natural gas, impurities mixed in the mixed oil and gas will adhere to the separation filter element in the oil-gas separator, causing the filter element to be easily blocked. Currently, most workers regularly remove the filter element for manual cleaning, which is inconvenient. For this reason, we designed an oil-gas separator to provide another technical solution to the above technical problems. Summary of the invention

[0004] Based on this, it is necessary to provide an oil-gas separator for the above technical problems. When the oil-gas separator is in use, the oil-gas mixture is poured into the interior of the separation box, and the oil-gas mixture is filtered and separated by the oil-gas separation filter element, so that the oil-gas mixture passes through the oil-gas separation filter element and is discharged from the exhaust pipe. Since the oil-gas mixture contains some particulate matter, the particulate matter will adhere to the outside of the oil-gas separation filter element and cause the oil-gas separation filter element to be blocked, thereby reducing the gas filtering effect in the oil-gas mixture and affecting the performance of the device. In order to solve the problem of clogging of the above-mentioned oil and gas separation filter element, water is injected into the inner side of the annular water pipe, and then the water is sprayed along the nozzle, so that the nozzle flushes the oil stains and particulate matter on the outside of the oil and gas separation filter element. At the same time, the lifting mechanism drives the T-shaped slider, nozzle and annular block to move up and down, so as to increase the cleaning effect of the nozzle and annular block on the oil and gas separation filter element, which is beneficial to improve the filtering and separation effect of the oil and gas separation filter element.
