Abstract

The invention discloses a graded utilization efficient energy-saving waste heat recovery system. The system comprises an installation frame, a filter box and a steam oven which are fixedly mounted onthe ground, a chimney, a first connecting pipe, a second connecting pipe and a third connecting pipe are sequentially installed on the installation frame from left to right, and the first connecting pipe, the second connecting pipe and the third connecting pipe are sequentially connected in a sealed manner. An air inlet pipe is installed at the upper end of the chimney, and an ash discharge pipe is installed at the lower end of the chimney. Through graded utilization of high temperature, medium temperature and low temperature of flue gas, the utilization efficiency of the system on flue gas waste heat is improved, through dust removal backflow of the filter box, heat loss is reduced, the combustion efficiency is improved, the utilization efficiency of the system on the flue gas waste heatis further improved, and smoke dust emission pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of waste heat utilization, in particular to a high-efficiency and energy-saving waste heat recovery system for graded utilization. Background technique [0002] During the use of the boiler, high-temperature flue gas will be produced. The direct emission of flue gas will not only increase the particulate matter in the air, but also increase the air temperature, resulting in greater air pollution. Therefore, it is necessary to cool down the flue gas and discharge it after dust removal. , and the cooling utilization of flue gas temperature helps the factory to save energy. [0003] Existing waste heat recovery systems usually only use waste heat boilers to heat water for heating or evaporate water into steam for power generation, which cannot effectively utilize the temperature in the flue gas through only one utilization, so that the exhausted flue gas still has relatively high High temperature and contains ...
