A cooling treatment system for iron oxide powder in acid regeneration station

Abstract

The invention relates to an acid regeneration station ferric oxide powder cooling treatment system. According to the acid regeneration station ferric oxide powder cooling treatment system, a block breaker and a roasting furnace rotating valve are mounted at the bottom discharge hole of a roasting furnace; the bottom discharge hole is further connected with a ferric oxide powder conveying pipeline; the ferric oxide powder conveying pipeline is connected with a ferric oxide powder bin through a plastic plate dust separator; a conveying fan is mounted on the ferric oxide powder conveying pipeline; a ferric oxide powder bin board plug valve and a ferric oxide powder bin rotating valve are mounted at the discharge hole of the ferric oxide powder bin; the discharge hole is further connected with a ferric oxide powder bagging machine; a section of air inlet pipeline is connected with the ferric oxide powder conveying pipeline which is connected with the lower part of the rotating furnace rotating valve at the discharge hole of the roasting furnace; an air inlet is formed in the wall of the air inlet pipeline; the air inlet pipeline is provided with a horizontal extension end; an air supplementing hole is formed in the axial end part of the horizontal extension end; a baffle is mounted on the air supplementing hole. The acid regeneration station ferric oxide powder cooling treatment system is reasonable in structural design and simple and convenient to operate, the cooling effect of ferric oxide powder can be improved, the high temperature resistance requirements of dust collection equipment can be effectively reduced, and the service life of equipment can be prolonged.

Description

technical field [0001] The invention relates to acid regeneration technology, in particular to a cooling treatment system for iron oxide powder in an acid regeneration station. Background technique [0002] As the main component of hazardous waste, industrial waste acid has great potential for resource utilization. Promoting the resource utilization of industrial waste acid can not only avoid environmental pollution and reduce the use of primary resources, but also give birth to new energy-saving and environmental protection industries and form new economic growth points. At present, the spray roasting waste acid regeneration process is mainly used to treat the waste acid liquid produced by cold-rolled pickling strip. This technology has been applied and popularized in domestic large and medium-sized iron and steel enterprises. [0003] The main body of hydrochloric acid regeneration process includes heat treatment system, heat exchange system, flue gas absorption system, ...

AI Technical Summary

Problems solved by technology

There is an air inlet on the air intake pipe, but there are problems such as small air intake, poor cooling effect, high iron powder temperature, and high requirements for subsequent dust separation equipment. The dust separation equipment has a short service life and increases production costs.
