Description

Technical Field

[0001] The utility model relates to the technical field of oily wastewater treatment, in particular to oil and gas field oily wastewater treatment equipment. Background Art

[0002] Oil and gas fields refer to the sum of oil reservoirs, gas reservoirs, and oil and gas reservoirs within the same area controlled by a single local structural unit. If there are only oil reservoirs within this local structural range, it is called an oil field; if there are only gas reservoirs, it is called a gas field. The oily wastewater produced by the oil and gas field needs to be treated to remove the emulsified oil and suspended matter it contains;

[0003] The existing oil and gas field oily wastewater treatment equipment has a simple overall structure and has no pre-filtration structure. It only relies on various filters for filtering, which increases the workload of the filter, thereby reducing the filtering efficiency and service life of the filter. Therefore, an oil and gas field oily wastewater treatment equipment is proposed. The oily wastewater can be pre-filtered by setting a filter block, and a cleaning component is set to clean the filter block to maintain its filtering efficiency. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides an oil and gas field oily wastewater treatment device, which can pre-filter the oily wastewater by setting a filter block, and set a cleaning component to clean the filter block to maintain its filtering efficiency.

[0005] The utility model solves the technical problem by adopting a technical solution of oil and gas field oily wastewater treatment equipment, comprising a circular shell, a filter block is fixed inside the circular shell by bolts, a cleaning assembly is arranged on one side of the circular shell, the cleaning assembly comprises a protection box fixed to one side of the circular shell by a flange, a driving motor is installed inside the protection box by a mounting frame, the output shaft of the driving motor located inside the circular shell is connected to a connecting rod by a connecting sleeve, a side plate is fixed to one end of the connecting rod by a flange, and a cleaning brush is fixed to one side of the side plate close to the filter block by bolts;

[0006] A booster pump is arranged at one end of the circular shell, and a filter assembly is arranged at one end of the booster pump away from the circular shell. The filter assembly includes a first organic ceramic membrane, a second organic ceramic membrane and a third organic ceramic membrane which are arranged in sequence on one side of the booster pump.

[0007] By adopting the above technical solution, the filter block in the circular shell pre-filters the oily wastewater, and the driving motor can drive the cleaning brush to rotate to clean one side of the filter block, so that the filter block maintains the filtering efficiency. The pre-filtered oily wastewater is then filtered through the first organic ceramic membrane, the second organic ceramic membrane and the third organic ceramic membrane.

[0008] Specifically, a first connecting pipe is fixed between the circular shell and the water inlet end of the booster pump via a flange, and a second connecting pipe is fixed between the water delivery end of the booster pump and the water inlet end of the first organic ceramic membrane via a flange.

[0009] Specifically, a third connecting pipe is fixed between the first organic ceramic membrane and the second organic ceramic membrane, and between the second organic ceramic membrane and the third organic ceramic membrane via a flange.

[0010] Specifically, the water outlet end of the third organic ceramic membrane is connected to a drain pipe via a flange.

[0011] Specifically, the bottom of the circular shell is connected to a drain pipe through a pipe, and one end of the circular shell located on the top of the protection box is connected to a water inlet valve through a pipe.

[0012] Specifically, the filter block is made of ceramic particle material.

[0013] Beneficial effects of the utility model:

[0014] (1) In the oil and gas field oily wastewater treatment equipment described in the utility model, the oily wastewater entering the circular shell is filtered by the filter block. The driving motor is turned on to drive the side plate to rotate through the connecting rod.

The filter assembly 3 includes a first organic ceramic membrane 301 , a second organic ceramic membrane 302 and a third organic ceramic membrane 303 which are sequentially disposed on one side of the booster pump 2 .

[0024] When in use, the filter block 8 in the circular shell 1 pre-filters the oily wastewater, and the driving motor 402 can drive the cleaning brush 404 to rotate and clean one side of the filter block 8, so that the filter block 8 maintains the filtering efficiency. The pre-filtered oily wastewater is then filtered through the first organic ceramic membrane 301, the second organic ceramic membrane 302 and the third organic ceramic membrane 303.

[0025] For example, Figure 1 As shown, the utility model also includes a first connecting pipe 5 fixed between the circular shell 1 and the water inlet end of the booster pump 2 through a flange, and a second connecting pipe 6 fixed between the water delivery end of the booster pump 2 and the water inlet end of the first organic ceramic membrane 301 through a flange.

[0026] When in use, the oily wastewater filtered in the circular shell 1 flows into the booster pump 2 through the first connecting pipe 5 , and is pressurized by the booster pump 2 and then transported to the first organic ceramic membrane 301 through the second connecting pipe 6 .
