Continuous fiber agglomeration coarse-grain oil eliminator

Abstract

The long-fiber agglomeration coarse-grained degreaser enables oil droplets to float along the filter layer in time under the lift of air bubbles through a reasonable filter layer structure, achieving the dual goals of coarse-grained and filtered oil removal. The oil remover includes oil removal reactor column (1), water inlet and overflow device (2), modified fiber bundle assembly (3), water outlet and backwash device (4), oil removal column connector ( 5), sampling port (6); the deoiling reactor column (1) is divided into upper and lower parts, which are connected into one by the deoiling column connector (5), and the deoiling reactor column (1) A modified fiber bundle assembly (3) is installed inside, a sampling port (6) is provided on the side of the deoiling reactor cylinder (1), and a water inlet and overflow are provided on the upper part of the deoiling reactor cylinder (1). The flow device (2) is equipped with a water outlet and backwashing device (4) at the lower part of the oil removal reactor column (1); the upper part of the device is fed with water, and the lower part is aerated to realize the agglomeration of oil droplets in the oily wastewater, the coarse to achieve oil-water separation.

Description

technical field [0001] The long-fiber agglomeration and coarse-grain degreaser of the present invention is an oil-water separation device for oily waste water, and belongs to the technical field of water treatment. Background technique [0002] Most of the existing oily wastewater treatment in my country is based on the old three sets of processes of "oil separation-air flotation-secondary biochemical", and supplemented by other treatment methods as needed. This process technology is mature, adaptable, and widely used, but it occupies a large area. The energy consumption and material consumption of the air flotation section of the core process are high, and the investment and operation costs are high, which is difficult for small and medium-sized enterprises to accept. Therefore, finding a technology that is efficient, stable, low in investment and operation costs, and reusable for oil removal has become an urgent problem to be solved. [0003] Studies in recent years have ...

Problems solved by technology

But at the same time, due to the poor hydrophilicity of the fiber itself, it sticks quickly after being stained with oil, making it difficult to wash off and regenerate.

In addition, due to structural defects (dead knot in the center of the fiber ball) of the currently developed fiber ball oil remover, it is difficult to elute and regenerate after oil absorption, and it is difficult to put it into use
