Petroleum production sewage treatment device convenient to clean

Abstract

The invention discloses a petroleum production sewage treatment device convenient to clean, and belongs to the field of petroleum sewage treatment.The petroleum production sewage treatment device convenient to clean comprises a shell, supporting legs are fixedly connected to the corners of the lower surface of the shell, and a treatment box is arranged at the upper end of the interior of the shell; an oil injection pipe is arranged in the treatment box, the upper end of the oil injection pipe penetrates through the treatment box and the shell at a time and extends to the outside, the outer surface of the oil injection pipe is in sliding connection with the treatment box, and the outer surface of the oil injection pipe is fixedly connected with the shell; when petroleum wastewater is injected into the treatment box, the sealing plate is opened by utilizing the buoyancy of the floating plate to automatically discharge water, then petroleum and floating impurities automatically enter the purification box, the petroleum and the floating impurities are treated by the purification pipe, and the petroleum and the impurities are automatically separated, so that the manual operation is simplified, and the treatment effect of the petroleum wastewater is improved; and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the field of petroleum sewage treatment, and more particularly, 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.

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
