An easy-to-clean sewage treatment device for petroleum production

Abstract

The invention discloses a sewage treatment device for petroleum production that is easy to clean, and belongs to the field of oil sewage treatment. A sewage treatment device for oil production that is easy to clean comprises a shell, and the corners of the lower surface of the shell are fixedly connected with Support legs, the inner upper end of the casing is provided with a processing box, the interior of the processing box is provided with an oil injection pipe, the upper end of the oil injection pipe penetrates the processing box and the casing at one time and extends to the outside, and the outer part of the oil injection pipe The surface and the treatment box are slidingly connected, and the outer surface of the oil injection pipe is fixedly connected with the shell; when the oil waste water is injected into the treatment box, the buoyancy of the floating plate is used to open the sealing plate to automatically discharge the water, and then the oil and floating impurities can be discharged. It automatically enters the purification box, and the oil and floating impurities are processed by the purification tube, and the oil and impurities are automatically separated, which simplifies the manual operation, improves the treatment effect of petroleum wastewater, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the field of petroleum sewage treatment, in particular to a sewage treatment device for petroleum production that is easy to clean. Background technique [0002] With the rapid development of modern science and technology, the gradual popularization of automation equipment, and the continuous improvement of people's living standards, our demand for oil is also increasing. The improvement of oil production and purity has led to the increase of the amount of petroleum wastewater, and people have paid great attention to petroleum wastewater, especially in the treatment of petroleum wastewater. [0003] Petroleum wastewater generally contains precipitated oil sludge, water, floating impurities, and petroleum; in the prior art to treat petroleum wastewater, the petroleum wastewater is generally injected into a sedimentation tank for precipitation, and the precipitated oil sludge will settle into the sedimentation tank. At the botto...

Problems solved by technology

[0003] Petroleum wastewater generally contains precipitated oil sludge, water, floating impurities, and petroleum; in the prior art to treat petroleum wastewater, the petroleum wastewater is generally injected into the sedimentation tank for sedimentation, and the precipitated oil sludge will settle into the sedimentation tank. At the bottom, the main components of oily sludge are sand and a small amount of mud. When there is a lot of oily sludge, the oily sludge in the sedimentation tank is usually extracted by a sludge pump. The step of extracting oily sludge requires personnel to operate and extract oily sludge. The sedimentation tank cannot be used at the end of the mud, and the treatment time of petroleum wastewater will be greatly delayed when the treatment volume of petroleum wastewater is large.

[0004] The oil and floating impurities floating on the water surface are generally pumped away by the oil pump, and then filtered through the filter screen; oil is also absorbed by oil-absorbing cotton, and then squeezed to obtain oil. The oil-absorbing cotton only absorbs oil but not water, and the remaining The water under the water and the floating impurities pass through the filter screen for solid-liquid separation, resulting in cumbersome treatment steps for petroleum wastewater and low treatment efficiency
