Abstract

The invention discloses a gas-floatation rotational-flow coalescence composite type sewage oil-removing device. The gas-floatation rotational-flow coalescence composite type sewage oil-removing device mainly comprises a multifunctional separating tank, a two-stage gas-water mixing device and an adjusting and control box, wherein liquid inlets are formed in the middle-upper part of the multifunctional separating tank, an oil outlet is formed in the middle part of the multifunctional separating tank, a water-soluble gas circulation device, a sewage discharging port is formed in the bottom of the multifunctional separating tank, and an gas exhaust port is formed in and a communicating pipe is arranged at the top part of the multifunctional separating tank. The multifunctional separating tank is internally provided with an inner rotational-flow drum, and the bottom of the multifunctional separating tank is connected with an oil outlet pipe. A gas mist catcher is arranged above the inner rotational-flow drum; a water collector at the lower part of the multifunctional separating tank is respectively connected with a water outlet and a circulatign water outlet of the multifunctional separating tank; a gas exhaust port in the top part of the separating tank is connected with an inlet of the two-stage gas-water mixing device by a pipeline. The water outlet of the separating tank is connected with a water inlet of the adjusting and control box at the side, and the top part of the adjusting and control box is communicated with the top part of the separating tank. The gas-floatation rotational-flow coalescence composite type sewage oil-removing device disclosed by the invention has the advantage that the technical problems of low efficiency, poor intensiveness, unstable operation and the like in the rotational-flow gas-floatation integration combined oil-removing technical equipment can be solved.

Description

technical field [0001] The invention relates to a novel integrated cyclone air flotation and coalescence multifunctional oil removal equipment, which is suitable for sewage treatment in oil and gas fields, sewage treatment in petrochemical industry and the like. Background technique [0002] With the improvement of the degree of oilfield exploitation, the exploitation technology is becoming more and more advanced, and the difficulty of water treatment is gradually increasing. At the same time, the development of various marginal oilfields and deep-sea oilfields also puts forward new requirements for water treatment technology. The traditional treatment unit has been It cannot meet the water treatment requirements, and the new oilfield water treatment technology is also developing in the direction of integration, high efficiency and intensification. [0003] At present, the water treatment methods widely used in oil fields are mainly physical separation and chemical agent ass...
