Spinning oil fume purifying device

Abstract

The invention discloses a spinning oil fume purifying device, which belongs to the technical field of synthetic fiber. The spinning oil fume purifying device comprises a shell; multiple anode tubes are vertically arranged in the shell; a cathode line is vertically hung in the centre of each anode tube; the upper part of each anode tube is inserted into an upper card, and the lower part of each anode tube is inserted into a lower card; the upper and lower cards, the outer walls of the anode tubes and the inner wall of the shell surround a closed cavity; the upper part of the cavity is communicated with a heat tracing steam inlet on the side wall of the shell; and the lower part of the cavity is communicated with a heat tracing condensed water outlet on the side wall of the shell. When oil fume passes through the anode tube, the oil fume particles mixed in the fume are charged under the action of an electric field and then adsorbed on a cathode and an anode. Through the invention, the accumulated oil stains are heated to 70-120 DEG C by the steam heat tracing so that the fluidity of the waste oil stains is maintained and the oil stains can smoothly flow into an oil collector on the bottom of the device,thereby guaranteeing the operation stability of the equipment and laying a good foundation for the collection of waste oil. The purifying device of the invention has notably good purifying effect and ensures that 95% of the oil fume in the waste gas can be removed.

Description

technical field [0001] The invention belongs to the technical field of synthetic fibers, and in particular relates to a safe, high-efficiency, and long-term stable operation of spinning oil fume exhaust gas purification treatment device. Background technique [0002] In the production process of synthetic fiber (precursor silk), especially during drawing, in order to increase the cohesion of the tow, reduce static electricity, and improve spinnability, it is usually necessary to attach a special oil for spinning on the surface of the sliver. The high temperature and high speed of the drafting roller will cause part of the volatile components of the spinning oil to volatilize into mist oil fume, which will be discharged to the outside through the suction device arranged above the drafting roller. If the fumes and exhaust gas diffuse in the surrounding area, a pungent smell will be generated, which will cause serious pollution of the oil fume and exhaust gas to the surrounding...

AI Technical Summary

Problems solved by technology

However, the sources of spinning oil fumes are relatively scattered. When the spinning oil fumes are sucked together through the suction ports above different spinning positions and reach the collector through long air ducts, the temperature drop is very large. very prone to agglomeration

Therefore, simply applying existing electric traps cannot completely solve the problem of spinning oil fumes
