Embodiment Construction

[0013] The specific structure, working process and best implementation mode of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] The structure of the vertical flow automatic oil separation and sedimentation device provided by the invention is as follows: figure 1 As shown, the device mainly includes a pool body composed of a separation zone 11 and a mud bucket 12, a water inlet pipe 1, a central guide tube 2 arranged on the upper part of the separation zone 11, a conical reflector 3 at the bottom of the central guide tube, and an outlet pipe 1. Water pipe 7, oil outlet pipe 8, mud discharge pipe 9, deflector 4, oil outlet weir 5 and water outlet weir 6. The deflector 4 is set in the separation area 11 and arranged concentrically with the central deflector cylinder. The upper part of the deflector has the same shape as the separation area 11, and its lower part is bell-shaped; the oil outlet weir 5 is installed on the ...

Abstract

The present invention is automatic vertical-flow oil-separating precipitator and belongs to the field of oil-bearing waste water treating technology. The precipitator includes a pond comprising separating area and mud bin, water inlet pipe, central guide barrel, conic reflecting board, water outlet pipe and mud discharging pipe. Inside the separating area, there is a guide board with lower bell mouth and coaxial with the central guide barrel, an oil discharge weir connected to the oil outlet pipe in the upper inside part of the guide board, and a water draining weir connected to the water outlet pipe inside the pone wall. The water inlet pipe is connected to the upper part of the central guide barrel. The present invention can separate oil automatically without need of mechanical driving, and is suitable for treating oil-bearing waste water to eliminate oil and suspended matter.

Description

technical field [0001] The invention relates to an automatic oil separation and sedimentation device for treating oily wastewater, belonging to the technical field of oily wastewater treatment. Background technique [0002] Oily wastewater is a large category of organic wastewater, mainly including wastewater from oil fields, mechanical processing (such as chain and machine parts processing), electromechanical processing (such as refrigerator, washing machine manufacturing, etc.) and catering industries, with high organic content and high oil content. characteristics, while some oily wastewater also contains a large amount of surface active substances, complex components, high degree of emulsification, poor biodegradability, and belongs to difficult-to-treat wastewater. [0003] Generally, oil removal treatment is often required for the treatment of oily wastewater, and the commonly used methods include sedimentation, adsorption, filtration and air flotation. Compared with ...
