Spiral flow diversion and hydrocyclone separation settling device

Abstract

The invention discloses a spiral flow diversion and hydrocyclone separation settling device. The spiral flow diversion and hydrocyclone separation settling device comprises a tank body, an overflow opening, a flow diversion cone, a flow diversion cap, an oil discharging opening, a slag discharging opening, a water collection opening, a water draining pipe, a water outlet, an upper filter plate, padding, a lower filter plate, a man hole, a spiral flow diversion tank, a water inlet, supporting legs and a sewage draining opening. According to the spiral flow diversion and hydrocyclone separation settling device disclosed by the invention, a spiral flow diversion and separation device is adopted, and the hydrocyclone separation effect is increased; the water outlet can be formed in the middle part of the tank body, so that stability of water quality of effluent water is realized, and dross is prevented from entering subsequent pipelines and equipment along with the effluent water; through arrangement of a padding layer, suspended matters can be effectively intercepted, and the suspended matters sink and fall into the spiral flow diversion tank when the gravity generated by gathering and accumulation of the suspended matters is greater than the buoyancy force of a treatment medium, so that the separation effect is achieved; double functions of hydrocyclone separation and gravity separation are utilized, so that the sedimentation rate is increased, standing time is not needed, and continuous settling separation can be realized.

Description

technical field [0001] The invention belongs to the environmental protection industries such as petrochemical and water treatment and the technical field of solid-liquid separation, and relates to a spiral diversion high-efficiency cyclone separation device. Background technique [0002] The invention and application of the cyclone separator was originally used for solid-liquid separation and liquid-liquid separation in the mineral processing process. separation, etc. With the development of cyclone separation technology, water treatment industry and increasingly stringent environmental requirements, various cyclone separators have emerged. Among them, hydrocyclone, as a new type of oil field produced water treatment equipment, stands out in the field of petroleum industry due to its compact structure, light weight, high efficiency, high space utilization, simple process and low cost. Years of scientific research experience, engineering practice and field application resul...
