High heat waste gas energy source utilization system

Abstract

The invention provides a high heat waste gas energy source utilization system, which comprises a combustion furnace, an air supplementing heat exchanger, a waste gas preheating heat exchanger, a full fresh air preheating heat exchanger, a drying box and an air suction motor, wherein the full fresh air preheating heat exchanger is connected onto the air supplementing heat exchanger through the air supplementing heat exchanger and is connected with the waste gas preheating heat exchanger through a pipeline, a full fresh air inlet is also formed in the full fresh air preheating heat exchanger, a full fresh air preheating fan is arranged between the full fresh air preheating heat exchanger and the full fresh air inlet, the waste gas preheating heat exchanger is also connected with a water heat exchanger through the full fresh air heat exchanger, and a waste exhaust fan is arranged on the water heat exchanger and is connected with a waste discharge opening. The high heat waste gas energy source utilization system has the advantages that the original pipeline heat energy can be greatly utilized, the energy consumption waste is reduced, the energy source utilization rate is improved, the generation of scale accumulation phenomenon at fan blades and pipelines caused by sudden cold and heat confluence can be avoided, the temperature of externally exhausted smoke gas is reduced, the energy is saved, the environment is protected, and the production cost is reduced.

Description

technical field [0001] The invention relates to a waste gas energy utilization system, in particular to a high-heat waste gas energy utilization system. Background technique [0002] Global resource shortage has always been a major bottleneck restricting industrial development. How to rationally and effectively save natural resources, develop and utilize renewable resources, and better adapt to the current production situation is the focus of research by scientists. The reutilization of waste heat resources of coke ovens has always been a place that coking enterprises tend to ignore, so it is necessary to comprehensively utilize the waste heat of high-heat exhaust gas. [0003] Availability of high-heat exhaust gas In actual production, the temperature of flue gas is generally around 180-300°C. For a long time, the heat of flue gas has not been effectively utilized, and it has been discharged to the outside atmosphere through the chimney, wasting available energy. waste hea...
