A high-toughness gangue brick sintering equipment with waste heat recovery function

Abstract

The invention discloses a high-toughness coal gangue brick sintering equipment with waste heat recovery function, which includes a heating furnace, a firing furnace, a chimney, a slag discharge pipe, a grid frame, a bracket and a gas supply mechanism. There is a firing furnace, the top surface of the firing furnace is inlaid with a chimney, the bottom of the heating furnace is installed with a slag discharge pipe, the inner cavity of the heating furnace is equipped with a grid frame, and the inner cavity of the firing furnace is installed with a bracket A water supply mechanism is installed on the bottom surface of the outer wall of the heating furnace, and an air supply mechanism is installed on one side of the top surface of the firing furnace. The present invention communicates with the first coil through the water supply mechanism and the gas supply mechanism and the second coil With the cooperation, the waste heat inside the heating furnace and firing furnace can be used multiple times, which reduces the waste of energy and saves the economic expenditure of the enterprise.

Description

technical field [0001] The invention relates to the technical field of sintering equipment, in particular to a high-toughness gangue brick sintering equipment with waste heat recovery function. Background technique [0002] The main component of coal gangue bricks is coal gangue. Coal gangue is solid waste discharged during the coal mining process and coal washing process. Its main components are Al2O3 and SiO2, and it also contains varying amounts of Fe2O3, CaO, MgO, Na2O, K2O, P2O5, SO3 and trace rare elements (gallium, vanadium, titanium, cobalt). [0003] The production cost of coal gangue bricks is lower than that of ordinary clay bricks. Using coal gangue to make bricks not only saves land, but also consumes mine waste. It is a low-carbon building material that is conducive to environmental protection. [0004] However, the existing sintering equipment for high-toughness coal gangue bricks has the following disadvantages: [0005] 1. The existing high toughness coal...

Problems solved by technology

[0006] The purpose of the present invention is to provide a high-toughness coal gangue brick sintering equipment with waste heat recovery function to solve the problem that the existing high-toughness coal gangue brick sintering equipment in the above-mentioned background technology does not have the waste heat recovery function when in use, so that high The direct discharge of heat after sintering of ductile gangue bricks not only increases the pollution to the environment, but also greatly wastes energy, which is not conducive to the economic development of enterprises.
