Petrochemical industry environment-friendly sewage treatment device

Abstract

The invention discloses a petrochemical industry environment-friendly sewage treatment device, which relates to the technical field of sewage treatment, and comprises a box body, the upper end of thebox body is provided with a filling port, the upper end of the box body is provided with a motor, the output end of the motor is connected with a main shaft, and the other end of the main shaft is fixedly connected with a transmission block I; first stirring frames are arranged on the side faces of the two ends of the transmission shaft in a bilateral symmetry mode, and the ends, away from the transmission shaft, of the first stirring frames are fixedly connected to a cross shaft. Under the transmission of the main shaft, the transmission block, the transmission shaft, the cross shaft, a limiting rod and a limiting ball head column, a first stirring frame and a second stirring frame drive corresponding stirring supporting rods and stirring blades to stir and mix, the sufficient mixing reaction of sewage and a flocculation agent is greatly improved, the local reaction of agents is prevented, the flocculation effect is improved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an environment-friendly sewage treatment device in the petrochemical industry. Background technique [0002] The petrochemical industry is the pillar industry of our country. It mainly processes and sells crude oil and natural gas. The production process includes oil and gas exploration, oil and gas field development, drilling engineering, oil production engineering, oil and gas gathering and transportation, crude oil storage and transportation, petroleum refining, chemical production, oil product sales, etc., to produce gasoline, kerosene, diesel oil, lubricating oil, and chemical raw materials needed by the society There are more than 3,000 kinds of petroleum and chemical products, such as synthetic resin, synthetic rubber, synthetic fiber, and chemical fertilizer, which are closely related to people's clothing, food, housing, and transportation. The petrochemical in...
