Description
Technical Field
[0001] This utility model belongs to the field of settling tank water distribution technology, specifically relating to a non-metallic water distribution device for settling tanks used in oilfield produced water treatment. Background Technology
[0002] During crude oil extraction, water from the oil reservoir is extracted along with the crude oil. Settling tanks are specifically designed to treat this produced water. Inside the settling tank, the produced water settles. The settling tank contains a water collection and distribution system, which collects and distributes the produced water. This system is typically made of corrosion-resistant non-metallic materials, such as high-performance plastics. This material choice is to cope with the complex chemicals in the produced water and prevent corrosion of metallic materials. The produced water entering the settling tank is collected by the water collection and distribution system and evenly sprayed into the settling tank through nozzles, facilitating the subsequent settling process.
[0003] However, existing water collection and distribution devices still have certain shortcomings in actual use. The extracted water contains a certain amount of dirt or silt, which can easily clog the nozzles on the water collection and distribution device, affecting the spraying of extracted water. Since the water collection and distribution device is generally installed inside the settling tank, it is not convenient to clean the dirt and silt. Therefore, a new water collection and distribution device needs to be designed to solve this problem. Utility Model Content
[0004] The purpose of this utility model is to provide a non-metallic water collection and distribution device for oilfield produced water treatment settling tanks, so as to solve the problem mentioned in the background art that the produced water inside the water collection and distribution device is easily blocked by dirt and silt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] After prolonged use, the nozzles of the water collection and distribution system may become clogged with dirt or silt in the extracted water. Personnel can periodically unclog the nozzles by pushing the strainer plate down with the fixed connecting rod, allowing the needle to be inserted into the nozzle to push out the dirt and silt blocking the nozzle, thus clearing the blockage. Clogging does not require opening the tank lid, making the operation simple and quick, and providing convenience for users. Attached Figure Description
