Cooling device for aluminum anode roasting furnace

Abstract

The invention aims to disclose an aluminum anode roasting furnace cooling device which comprises a main pipe, an annular pipe, a temperature measuring element and a controller, the annular pipe is arranged on a flue of a smoke exhaust frame in a sleeving mode, spray pipes are evenly arranged on the periphery of the annular pipe and extend into the flue of the smoke exhaust frame, and the temperature measuring element is arranged on the main pipe. One end of the main pipe is connected with the annular pipe, the other end of the main pipe is connected with a steam pipe through an electromagnetic valve, the temperature measuring element extends into a gas collecting cylinder of a main flue, and the controller is in communication connection with the electromagnetic valve and the temperature measuring element in a wired or wireless mode; compared with the prior art, the steam enters the flue through the electromagnetic valve, the annular pipe and the spraying pipe, the steam is sprayed to the flue, the flue is cooled, tar can be fully burnt, hazardous waste is reduced, natural gas is reduced, cost is saved, convenience and feasibility are achieved, implementation is easy under existing conditions, and the purpose of the invention is achieved.

Description

technical field [0001] The invention relates to a cooling device for a roasting furnace, in particular to a cooling device for an aluminum anode roasting furnace which is widely used for cooling the flue in the metallurgical industry. Background technique [0002] The green products pressed before firing are composed of calcined coke, residual poles and asphalt binder of different particle sizes. Asphalt binder is a thermoplastic substance, its composition is mostly organic matter, and its conductivity is poor. Therefore, although the raw product has a certain strength and shape at room temperature, it is easy to bend, deform and brittle, not resistant to impact, and almost non-conductive. Therefore, the pressed raw products do not have performance requirements such as strength, heat resistance, corrosion resistance, electrical conductivity, and thermal conductivity. Binder coking to achieve full volume shrinkage. [0003] When the anode raw block is burned, a large amount...
