Problems solved by technology

[0003] However, the existing walnut shell filter has the following problems, such as the filter material cannot be cleaned, and the labor intensity of workers is high.
At the same time, after the walnut shell filter works for a long time, when the oil on the surface of the filter material reaches a certain thickness, the pressure inside the device will increase and the filtration capacity will decrease, which will cause damage to the walnut shell filter and affect the use effect of the walnut shell filter. The hardened and large oil stains cannot be broken during backwashing, resulting in blockage of the overflow port, and the oil stains during flushing cannot be removed

Abstract

The invention discloses a walnut shell filter, which comprises a walnut shell filter body, a three-cylinder pump and a stirring device. The upper end of the walnut shell filter body is provided with a pipe-type water distribution device. The pump communicates with the first annular pipe, the first annular pipe, the second annular pipe and the third annular pipe are all provided with spray holes, the lower end of the walnut shell filter body is provided with an integrated water collection device, the The upper end of the integrated water collecting device is provided with a water collecting plate, and the integrated water collecting device is provided with a walnut shell filter material layer. The present invention uses the pressure of the three-cylinder pump to achieve the effect of uniform water distribution under the cooperation of the water inlet pipe, the first annular pipe, the second annular pipe, the third annular pipe and the spray hole, and can also completely solve the problem of filter material hardening, oil Technical problems of backwashing such as staining.

Description

technical field [0001] The invention belongs to the technical field of oil recovery in oil fields, and in particular relates to a walnut shell filter. Background technique [0002] Hydraulic flooding is a commonly used method of oil recovery in oilfields. During water flooding in oilfields, the comprehensive water content of the reservoir continues to rise, and the amount of sewage treatment is increasing. In order to save water resources and prevent environmental pollution, it is necessary to treat oily sewage Among the common oily sewage treatment filters currently on the market, walnut shell filters occupy a large market share due to their large processing capacity, good treatment effect, and simple operation. [0003] However, the existing walnut shell filter has the following problems, such as the filter material cannot be cleaned, and the labor intensity of workers is high. At the same time, after the walnut shell filter works for a long time, when the oil on the surf...
