Centrifugal separation and recycling device

Abstract

The invention discloses a centrifugal separation and recycling device. The centrifugal separation and recycling device comprises a shell, wherein a filtering cartridge is arranged in the shell; spiraltype flow guiding blades are distributed on the surface of an outer circumference of the filtering cartridge; an oil-gas inlet pipe is arranged on one side of the shell; an oil-gas separation umbrella is arranged on the top of the shell; oil dispersion plates are arranged on the inner surface of the filtering cartridge, are uniformly distributed on the inner surface of the filtering cartridge andextend downwards aslant along the center of the filtering screen; a gas outlet is formed in the top of the shell; an oil-liquid drainage pipe is arranged at the bottom of the shell; and the top end of the oil-liquid drainage pipe is positioned below the oil dispersion plates and can enable the oil liquid accommodated on the oil dispersion plates to flow into the oil-liquid drainage pipe. By adopting the structure, through skillful structural design, operation is carried out in a swirling flow centrifugation way, so that a separation effect is greatly improved; and additionally, through arrangement of the oil dispersion plates, an efficient treatment effect of gas-liquid separation is realized again, and the oil liquid can successfully flow into the oil-liquid drainage pipe, and thus, theproblems of wastewater, secondary pollution and the like are avoided, and the treatment cost is greatly reduced.

Description

Technical field

[0001] The invention relates to a separation and recovery device, in particular to a centrifugal separation and recovery device. Background technique

[0002] In the process of waste gas recovery and treatment in oil product loading and transportation occasions such as oil depots, refineries, and docks, it is necessary to recover the toxic and harmful waste gas emitted into liquid oil, which can avoid the discharge of a large number of pollutants and at the same time have a greater recovery economy benefit.

[0003] In the prior art, the waste gas generated in these occasions is basically untreated and directly discharged. In some cases, washing + adsorption method, low temperature plasma removal method, and oxidation incineration method are used. These treatment methods can achieve certain effects, but often there are problems in treatment. If it is in place, a large amount of waste water will be generated, secondary pollution will be formed, and the treatment cos...
