Method and device for capturing complex flue gas on smelting pot surface

Abstract

The invention relates to a method and a device for capturing complex smoke on the surface of a smelting pot. The method comprises the following steps: arranging a cover on an edge opening of the smelting pot to cover the edge opening, and forming an opening for a stirring shaft to enter and exit in the center of the cover top; the cover top is provided with a plurality of flap plates and a flue gas pipeline connected with a dust collecting system, and the movable cover plate can be opened and closed, so that the requirements of feeding, slag salvaging and observation of the smelting pot are met, and meanwhile, the flue gas is prevented from leaking; an automatic reset feeding flap plate is arranged at the connecting position of the rear end of the cover cap and the feeding device, the flap plate is pushed open during feeding, automatic reset closing is achieved after feeding, and it is guaranteed that smoke does not leak out. The cover top of the device is divided into a feeding melting area, a stirring operation area, a flue gas collecting area and a feeding and slag salvaging operation area which are respectively provided with a feeding loose blade, a sealing loose blade, a flue connected with a dust collecting system and a slag salvaging loose blade. The method and the device provided by the invention are easy to manufacture and install, simple and convenient to operate, and capable of fully capturing flue gas to ensure normal operation of a dust collection system without influencing normal implementation of various operations of a pot surface platform.

Description

Technical field [0001] The present invention relates to the field of metal smelting environmental protection auxiliary equipment, specifically to a smelting pot surface complex flue gas capture method and apparatus. Background [0002] In the process of metal smelting and pyrogenic refining and impurity removal, in order to obtain a loose entrainment of less slag or targeted removal of a certain impurity metal, it is often necessary to add chaff, rosin, sulfur, caustic soda and other materials in the refining and impurity removal process to reduce the proportion of scum to promote the separation and settlement of molten liquid metals. At the same time, the electrolytic cathode precipitate or residual electrode returns to the smelting of the acidic electrolyte, etc. in the high temperature melting process to form a large number of low temperature acid and alkali containing alkali and dust containing water complex flue gas, worsening the operating environment of the pot surface pla...
