Abstract

The invention discloses an oily sewage separator. There is at least an inlet on the shell at one end of the separator, and at least an outlet on the other end of the shell; a pretreatment device is arranged in sequence from the inlet to the outlet, which is used to settle and store the sludge in the oily sewage; the inclined plate separation device, its top and bottom The ends are closely connected with the top and bottom of the separator for primary oil-water separation; the top and bottom of the coagulation separation device are tightly connected with the top and bottom of the separator for secondary oil-water separation; the sewage conveying device, It is used to accommodate and transport the sewage to be discharged; the top of the sloping plate separation device and the coagulation separation device is provided with an oil tank for receiving and containing the separated oil; the outlet is connected with a delivery pump for pumping the sewage out of the separator. The separator can separate oil droplets with a particle size of more than 20 microns, and the oil removal rate is 99%. The separated sewage meets the national A1 oilfield water injection standard, and the cost is reduced by half, low energy consumption, small size, and a service life of 5-8 years.

Description

technical field [0001] The invention relates to the technical field of oil-water separation, in particular to an oily sewage separator. Background technique [0002] With the continuous extraction of oil, the purity of oil will decrease, so it is particularly important to improve the utilization rate of oil, which involves the efficient separation of oil. [0003] The main factor affecting liquid-liquid separation is the diameter of the separated droplets. The larger the particle size of the liquid, the easier it is to separate, and the smaller it is, the harder it is to separate. The separation process is a process in which the light phase gathers above the mixed liquid and the heavy phase gathers below the mixed liquid. [0004] In order to separate water and oil in crude oil, the commonly used chemical separation method is to add chemical reagents, such as demulsifiers or flocculants. Due to the addition of chemical reagents, the environment is polluted and the separatio...
