Novel sewage treatment purification and drying unit

Abstract

The invention relates to a novel sewage treatment purification and drying unit. The specific structure is as follows: a chemical measuring pump is connected to a prize rack through a bolt; a connecting circular tube and a vortex high-energy mixer are welded into an integral body and integrally fixed to a floatation tank through bolts; the floatation tank is fixed to the prize rack through a bottom connecting seat; a slag scraper is fixed to the floatation tank through a bearing carrier; a motor single bond is connected to a slag scraper shaft; a solid residue collecting box is welded onto the floatation tank; a funnel is fixed to a laminating machine through a bracket; the laminating machine, a discharge pump and a sewage suction pump are respectively fixed to the prize rack by bolts through the bracket; and a gas storage tank is fixed to the floatation tank through bolts. The purification and drying unit has high sewage treatment capacity, reduces the scum yield, reduces the integral occupied area, and enhances the water treatment effect.

Description

technical field [0001] The invention relates to a sewage purification and drying device in an oilfield water treatment system, which can be used for solid-gas-liquid three-phase mixers of air flotation systems in various oilfield sewage stations and sewage purification sites and for drying solid residues. It is related to the environmental protection field of oil and gas field exploitation. Background technique [0002] As the country pays more and more attention to environmental protection, higher requirements are put forward for the environmental protection of oil and gas field exploitation, and oilfield sewage treatment is an important influencing factor; the main way of oilfield sewage treatment in the market at present is: firstly pass the sewage through Air flotation treatment is carried out after the blue filter, rotary desander and inclined plate degreaser, and then pumped back to the bottom of the well. This treatment method can only purify the liquid in the sewage...

AI Technical Summary

Problems solved by technology

This treatment method can only purify the liquid in the sewage and discharge it, and cannot directly treat the solid residue. New equipment is required to reprocess the residue

This aspect directly increases the cost of sewage treatment, and the traditional air flotation device has too large a diameter of the microbubbles generated by the mixer, which leads to a decrease in its adsorption effect on suspended solids in sewage, and the sewage treatment cannot achieve the ideal degreasing effect ; On the other hand, the maneuverable space of the well site is greatly compressed, resulting in a waste of resources
