Problems solved by technology

The traditional exhaust gas discharge chimney originally adopts a cylindrical structure. The exhaust gas is directly discharged through the chimney, and the acid mist in the discharged exhaust gas condenses and settles around the chimney, causing the surrounding equipment to be corroded and the environment polluted; the condensed acid liquid flows along the outer wall of the chimney to Bolts are corroded at the flange, which creates a large potential safety hazard for equipment

Abstract

The invention discloses an acid mist sedimentation apparatus, which comprises a dual tapered cylindrical casing, wherein the dual tapered cylindrical casing comprises an upper tapered cylindrical casing and a lower tapered cylindrical casing, the upper end of the upper tapered cylindrical casing is provided with a gas discharge port, the lower end of the lower tapered cylindrical casing is provided with a connection port, and the connection port position is provided with a connection flange. The acid mist sedimentation apparatus is characterized in that an annular baffle is arranged inside the lower tapered cylindrical casing, the bottom of the annular baffle and the inner wall of the lower tapered cylindrical casing form a fixed connection to form an annular collection groove, the bottom of the annular collection groove is further provided with a diversion pipe, and the diversion pipe and an annular diversion groove are communicated. With the invention, the problem that peripheral equipment is corroded due to sedimentation of a large amount of acid mist in waste gas is effectively solved, important significances are provided for environmental pollution reduction and plant and surrounding environment improvement, and the collected acid liquid can be used for new acid regeneration so as to reduce a production cost and save resources.

Description

technical field [0001] The invention relates to a cold rolling acid regeneration equipment, in particular to an acid mist settling device. Background technique [0002] At present, the waste gas produced in the cold-rolled acid regeneration process contains a large amount of acid mist, and the waste gas is finally discharged into the surrounding atmosphere through the waste gas fan and chimney. The traditional exhaust gas discharge chimney originally adopts a cylindrical structure, and the exhaust gas is directly discharged through the chimney, and the acid mist in the discharged exhaust gas condenses and settles around the chimney, causing the surrounding equipment to be corroded and the environment polluted; the condensed acid liquid flows along the outer wall of the chimney to Bolts are corroded at the flange, which poses a large equipment safety hazard. Contents of the invention [0003] The technical problem solved by the present invention is to provide an acid mist ...
