Abstract

The invention discloses a coagulation separation device and relates to the technical field of oil water separation. The coagulation separation device provided by the invention comprises a frame and aplurality of coagulation nets fixed in the frame; each coagulation net comprises a plurality of unit filtering nets; each unit filtering net is a hollow reverse rectangular pyramid which is formed byweaving polyvinyl chloride silk transversely in one direction, has the bottom surface facing upwards and is opened; the filtering nets with upward openings are mutually connected to form the coagulation net; the distance between the adjacent two pieces of polyvinyl chloride silk is 0.3 mm to 0.5 mm; the polyvinyl chloride silk is cuboidal; when the coagulation net with the upward opening is horizontally placed, the side surface of the reverse rectangular pyramid and the horizontal direction form an included angle of 10 to 30 degrees; and oil-containing sewage enters from the opening ends of the coagulation nets, oil drops are intercepted at the gap position between the polyvinyl chloride silk, water passes through the gap position and oil water separation is realized. The coagulation separation device provided by the invention can separate the oil drops with the grain size of 20 microns to 40 microns, and has good separation effect.

Description

technical field [0001] The invention relates to the technical field of oil-water separation, in particular to a coagulation and separation device. 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 th...
