System for heating batch by utilizing secondary waste heat of float glass furnace

Abstract

The invention relates to the technical field of waste heat utilization of a float glass furnace, aiming at solving the technical problems which are present during the operation of waste heat generation systems of the traditional float glass furnaces, such as low recovery rate of waste heat, severe environmental pollution caused by emission of smoke containing a large amount of dust, unstable system operation and the like. A smoke outlet of the float glass furnace of the invention is communicated with a smoke inlet of a waste heat boiler; a smoke outlet of the waste heat boiler is communicated with an inlet of a waste heat draft fan; an outlet of the waste heat draft fan is communicated with an inlet of a rotary dryer through a flue, a charging hole is arranged above the inlet of the rotary dryer, an outlet of the rotary dryer is provided with a downward material outlet end and an upward flue respectively; the upward flue is communicated with a helical conveyor above which a dust collector is arranged; a discharge hole of the helical conveyor and a material outlet end of the rotary dryer are connected with a kiln head feeding bin, and a smoke outlet of the helical conveyor is communicated with a system draft fan and a chimney. The invention is suitable for the waste heat utilization of the float glass furnace.

Description

technical field [0001] The invention relates to the technical field of utilization of waste heat of a glass melting furnace, in particular to a batch material heating system utilizing the waste heat of a float glass melting furnace boiler waste gas. Background technique [0002] The energy consumption of industrial processes is dominated by fuel and electricity. Usually, the utilization rate of fuel is between 30% and 40%, and a large amount of residual energy will be generated, and most of the residual energy exists in the form of exhaust heat. If the exhaust gas waste heat resources are not recycled, it will not only waste energy, but also pollute the environment. Utilize the waste heat resources of industrial processes to build waste heat power plants, and on this basis to realize the reuse of waste heat power generation and exhaust flue gas. Comprehensive utilization of technological transformation projects, its economic benefits, environmental benefits and social benef...
