High-fluorine organic matter treatment process

Abstract

The invention discloses a high-fluorine organic matter treatment process which comprises the following steps: P1, adding a high-fluorine organic matter emulsion into a closed stirrer to obtain floccules; P2, conducting filtering and separating by using a filter screen to obtain floccules and separated wastewater; P3, adding the floccules into a centrifugal machine to obtain centrifugal floccules and centrifugal wastewater; P4, adding the centrifugal floccules into a drying box, conducting drying for 1-2 hours under the condition of 150-160 DEG C, and collecting drying steam to obtain dried floccules; P5, obtaining high-fluorine wastewater and conducting post-treatment; P6, placing the dried floccules in a closed container, heating the dried floccules to 350-380 DEG C by irradiation of radioactive rays, and then cooling the dried floccules to obtain treated floccules and treated tail gas; and P7, carrying out heat treatment to obtain a powdery substance, thereby completing the treatment of the high-fluorine organic matters. The generation and emission of pollutants are greatly reduced, the treatment quality and efficiency are ensured, and the process is beneficial to popularization and application.

Description

technical field [0001] The invention relates to the technical field of high-fluorine organic substances, in particular to a treatment process for high-fluorine organic substances. Background technique [0002] In the current industrial production, organic substances with various components are used, among which high-fluorine organic substances are common ones, such as polytetrafluoroethylene, which can be widely used in the production of coatings, paints, etc., and in order to ensure Masses of added high fluorine organics, which need to be disposed of, form fine powders. [0003] However, when the existing polytetrafluoroethylene high-fluorine organic substances are disposed of, most of them are crushed through polytetrafluoroethylene finished materials, which not only causes poor fineness of the powder, but also relatively rough powder particles, which affects the quality of additives. During powder treatment, more high-fluorine wastewater and tail gas are likely to be pro...

Problems solved by technology

[0003] However, when the existing polytetrafluoroethylene high-fluorine organic substances are disposed of, most of them are crushed through polytetrafluoroethylene finished materials, which not only causes poor fineness of the powder, but also relatively rough powder particles, which affects the quality of additives. During powder treatment, it is easy to produce more high-fluorine wastewater and tail gas, which is not conducive to separate treatment. Direct discharge is likely to cause pollution and poor safety. A new disposal process method needs to be proposed
