Skid-mounted water purifying device of oil producing wastewater

Abstract

The invention discloses a skid-mounted water purifying device of oil producing wastewater, comprising a skid bottom plate, a water purifier and a self-washing filter, wherein the water purifier and the self-washing filter are arranged on the skid bottom plate; the water purifier comprises a water purifier shell and a top plate; the water purifier shell is internally provided with a central water distributing pipe, an inclined pipe solid-liquid separation device and a water feeding pipe; the top plate is connected with an oil scraper and a mud discharging mechanism is arranged at the bottom of the central water distributing pipe and a water inlet pipe of the water purifier is connected with the lower part of the central water distributing pipe; the top of the central water distributing pipe is connected with an oil-water separation partition plate; the oil-water separation partition plate is connected with a plurality of flow guide pipes; the lower parts of the flow guide pipes are connected with trumpet-opening-shaped water distributing pipes; the bottom of the oil scraper is connected with an oil collecting pipe and the water purifier shell is connected with an oil discharging pipe; and the water inlet pipe of the water purifier, which is connected with the self-washing filter, is connected with a water outlet pipe of the water purifier. The skid-mounted water purifying device of the oil producing wastewater disclosed by the invention has the advantages of compact structure, novel and reasonable design, strong configuration flexibility, simplicity and convenience for operation, safe, stable and reliable operation, good treatment effect on the oil producing wastewater, strong practical applicability, and high popularization and application values.

Description

technical field [0001] The invention relates to the technical field of oil production wastewater treatment, in particular to a skid-mounted water purification device for oil production wastewater. Background technique [0002] In the process of crude oil extraction, the effective treatment of oil extraction wastewater is not only related to environmental safety, but also a key link in the increase of production and sustainable development of oil extraction enterprises; and the reinjection of oil extraction wastewater after treatment has become a key to reduce environmental pollution and improve economic benefits of oil fields. important way. [0003] Suspended solids SS and oil in oil production wastewater are two important factors that lead to plugging of injection wells and oil layers in oil production wastewater reinjection. At present, domestic oil production wastewater treatment can be roughly divided into gravity oil collection, sedimentation, and filtration process a...

Problems solved by technology

The one-time construction investment cost of the existing treatment process facilities is high, the facilities are complete, the area is large, and the construction period is long (3 to 6 months). All the facilities and equipment in the station construction equipment are fixed and cannot be reused, and the equipment configuration is flexible. Insufficient; on site, the operator determines the dosage of chemicals according to the water quality, and determines the backwashing, sludge discharge and standby working conditions of the filter equipment. In the case of large changes in the quality of wastewater, the design capacity of the equipment is insufficient, and the impact load capacity Poor problems will be exposed, and the quality of effluent water cannot be reliably guaranteed
