Novel oil removal process for coal chemical industry wastewater

Abstract

The invention discloses a novel oil removal process for coal chemical industry wastewater, and belongs to the technical field of coal chemical industry, the novel oil removal process comprises the following steps: performing preliminary separation through an oil-water separator, injecting into an oil removal tank, uniformly putting oil removal balls, and continuously absorbing residual oil drops in the wastewater in the sinking process of the oil removal balls, meanwhile, the buoyancy change brings the breathing action of the oil removal ball, surrounding wastewater can be intermittently attracted to approach the oil removal ball, so that the dynamic adsorption effect is utilized to expand the oil absorption range and improve the oil absorption effect, and the oil removal ball is in matched contact with the magnetic ball at the bottom of the tank after sinking, so that the expansion action of the oil removal ball is completely triggered, When the oil removal ball works, the buoyancy action on the oil removal ball is increased, then the oil removal ball gradually floats upwards, meanwhile, the oil removal ball synchronously triggers the local closing action under the unfolding action, closing protection is conducted on an oil absorption area, oil contamination is prevented from flowing back into wastewater to cause secondary pollution, and the oil removal effect on the coal chemical industry wastewater can be effectively achieved.

Description

technical field [0001] The invention relates to the technical field of coal chemical industry, and more specifically, relates to a novel degreasing process for coal chemical wastewater. Background technique [0002] Coal chemical industry refers to the process of using coal as raw material and converting coal into gas, liquid and solid fuels and chemicals through chemical processing. It mainly includes coal gasification, liquefaction, dry distillation, tar processing and calcium carbide acetylene chemical industry. Coal Chemical Processing Process. The chemical structure of organic matter in coal is a macromolecular structure with aromatic-based condensed rings as the unit core, interconnected by bridges, and various functional groups. Through thermal processing and catalytic processing, coal can be converted into various fuels and chemicals. [0003] As an important component of my country's energy structure, coal energy plays a vital role in ensuring the security of my ...

Problems solved by technology

[0004] There will be a large amount of wastewater in the existing coal chemical production, and the wastewater contains oil. Traditionally, oil-water separators are used for separation. However, in the actual separation process, there are many tiny oil droplets in the wastewater that are difficult to separate in a stable form, resulting in The oil-water separation effect of wastewater is not good
