Modified fiber ball filter and its automatic cleaning control system for oil field

Abstract

The invention discloses a modified fiber ball filter for an oil field, which comprises a housing, a main shaft and a lifting device. The upper sides of the housing are provided with filtrate inlets, and one side of the middle part of the housing is provided with filter packing inlets and outlets. An observation hole is provided on the other side of the middle part, filtrate outlets are provided on both sides of the lower part of the housing, a lifting device controller is provided in the middle of the upper part of the housing, a stirrer is provided in the middle of the lower end, and a The baffle, the filtrate inlet and the filtrate outlet are respectively provided with an electronic valve, the filtrate inlet is respectively provided with a cleaning water inlet, the cleaning water inlet is also provided with an electronic valve, and is externally connected to a cleaning water pump. The cleaning device and the filter are integrated to reduce the handling and setting of the corresponding device. At the same time, it also provides an automatic cleaning control system for the modified fiber ball filter used in the oil field, which makes the filter automatic, and the automatic cleaning effect is remarkable. Save Time and labor saving, so that the filter can adapt to the production needs, and improve the working efficiency of the filter.

Description

technical field [0001] The invention relates to the technical field of purification filters, in particular to a modified fiber ball filter for oil fields and an automatic cleaning control system thereof. Background technique [0002] At present, domestic oil field filters mainly include quartz sand filters, walnut shell filters, fiber ball filters and a small amount of fiber bundle filters. Among them, the quartz sand filter is a filter using quartz sand as a filler. Although it has the advantages of small filtration resistance, large specific surface area, strong acid and alkali resistance, and good pollution resistance, it has low precision for sewage treatment. It is difficult to meet the water quality index requirements of low-permeability oil field injection; the walnut shell filter uses walnut shell as the filter medium, because the walnut shell used as the filter medium has been specially treated, so it has a large surface area, strong adsorption capacity, and high re...

Problems solved by technology

[0003] However, there are several defects in the existing fiber ball filter. First, in the process of filter filtration, since the filter plate arranged under the filter filler has a structure of holes and grooves, it is inevitable that some parts will not be filtered or completely filtered. The sewage directly flows out of the device through the filter plate, resulting in the poor quality of the oilfield water injection, which makes the water injection more and more unable to meet the needs

Among the fiber ball filter fillers used today, although the filter effect is very good, the existing filters do not have an automatic cleaning function, and all need manual cleaning, with a low degree of automation
