Ring type roasting furnace

Abstract

The invention discloses a ring type roasting furnace, and relates to the field of roasting furnaces. The ring type roasting furnace comprises a furnace shell; flame paths and furnace chambers communicating with the flame paths are formed in the furnace shell; material boxes are further embedded in the furnace shell; one material box is arranged between every two flame paths; the furnace chambers are formed in the positions, located below the flame paths, inside the furnace shell and communicate with the flame paths; the furnace chambers are partitioned through partition plates; an ignition device is arranged in each furnace chamber; a guide pipe is arranged on each partition plate in a penetrating mode; a fuel cavity is formed in the position, surrounding the furnace chambers, inside the furnace shell in a ring shape; and a fuel gas inlet pipe communicating with the fuel cavity is arranged on one side of the furnace shell in a penetrating mode. The ring type roasting furnace has the advantages that a flue gas filtering device is arranged, exhausted hot gas can be filtered by the flue gas filtering device, so that the hot gas and waste gas in a furnace body can be sufficiently filtered in the emission process so as to filter out particulate impurities in flue gas and toxic and harmful gas in the flue gas, and therefore the flue gas can accord with the emission standard, and thering type roasting furnace can be more environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of roasting furnaces, in particular to a ring-type roasting furnace. Background technique [0002] The roaster is the most critical large-scale thermal furnace equipment for the production of carbon products. For a prebaked anode production plant, the infrastructure investment of the ring roaster accounts for 50% to 60% of the total investment of the entire carbon plant, and the roasting The advancement of furnace design and technology has a great impact on product quality, unit investment, production capacity, energy consumption and comprehensive energy utilization, furnace life, and product production costs. The design of the roasting furnace flue wall structure, material selection and construction Process is the most critical technology in designing a roaster. [0003] However, the current roasting furnace has problems such as high energy consumption, high air leakage rate of the system, uneven temperatu...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a ring-type roasting furnace, which has the advantages of environmental protection and energy saving, and solves the problems of high energy consumption, high air leakage rate of the system, uneven temperature difference in the fire path, and heat loss in the current roasting furnace mentioned in the background technology. Too many, the side wall is deformed and the side fire channel is squeezed, the size of the material box is unreasonable, and the filling rate is low, etc.
