Abstract

The invention discloses pressure type rotational-flow air floatation separation equipment for treating oily wastewater. The pressure type rotational-flow air floatation separation equipment comprisesa separation tank, wherein a collecting tank is arranged on one side of the separation tank, rotating shafts are arranged on the two sides of the upper end of the separation tank, the outer sides of the rotating shafts are sleeved with a conveying belt, scraper blades are arranged on the two sides of the conveying belt, a second motor is arranged on one side of the upper end of the separation tank, a driving wheel is arranged at the front end of the second motor, an aeration area is arranged on one side of the separation tank, an aerator is arranged at the bottom end of the separation tank andlocated in the aeration area, a first motor is arranged at the upper end of the separation tank and located over the aeration area, a shaft rod is arranged at the bottom end of the first motor, and aturbine is arranged at the bottom end of the shaft rod. In the separation process, the first motor can drive the shaft rod to rotate, the shaft rod can drive a turbine to stir liquid in the aerationarea in the rotation process, power in the aeration area is increased, and bubble attachment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment equipment, in particular to a pressure-type cyclone air flotation separation equipment for oily wastewater treatment. Background technique [0002] Oil-water separation technology is very popular in the petroleum and petrochemical industry. The commonly used separation methods are gravity sedimentation method, air flotation method, filtration method, centrifugal separation method and so on. Each method has its advantages and disadvantages and its scope of application. The air flotation method has mature technology, low cost, and large processing capacity, and has been widely used. The disadvantage is that the residence time is long, generally about 30 minutes, and it occupies a large area. Due to the short residence time of the cyclone, only a few seconds, and high separation efficiency, it has been widely used in my country. However, since the cyclone is separated by the centrifugal ...
