Abstract

The invention discloses a composite dryer capable of recycling flue waste heat. The composite dryer capable of recycling the flue waste heat comprises a drying channel section, a heat source section and a circulating fan section, the heat source section and the circulating fan section are arranged at two ends of the drying channel section, and hot air generated by the heat source section passes through a hot-air air channel and flows into the drying channel section by means of drafting of the circulating fan section. The heat source section comprises a suction and draft fan, a combustion furnace and a heat-exchange cavity plate, the heat-exchange cavity plate is formed by connecting a plurality of serially-connected or parallelly-connected cavity plates and sleeved at a flue gas outlet of the combustion furnace, a furnace ash settler is further arranged at the bottom of the heat-exchange cavity plate and integrally formed with the same, a flue waste-heat heat exchanger is further arranged on the top of the drying channel section, a flue gas pipeline is arranged on the sidewall of the flue waste-heat heat exchanger, a tube pass of the heat exchanger is communicated with the heat-exchange cavity plate of the heat-source section via the flue gas pipeline, and fresh air is communicated with the heat source section after entering a shell pass. The composite dryer capable of recycling the flue waste heat has the advantages that circulating hot air and flue waste heat are recycled efficiently, use ratio of fire coal is increased greatly, drying cost of agricultural products is reduced, and environmental protection is benefited.

Description

[0001] technical field

[0002] The invention mainly relates to a composite dryer for efficient utilization of heat energy. Background technique

[0003] At present, all the traditional earth method brick drying tunnels and coal-fired furnaces used in the drying equipment are used in rural areas. The baking process is mastered by the experience of the baking master. The continuous control of fuel, temperature, and humidity is unstable, resulting in unstable product quality, high energy consumption, heavy smoke ash layer pollution, and high overall cost of baking. Due to the limitations of the structure, it is difficult to repair the equipment and take a long time, especially the fresh goods are not easy to stand for more than 24 hours and spoil, resulting in waste of raw materials. And the utilization of heat energy is very low, and the combustion heat energy of the fuel cannot be recycled, resulting in an increase in cost. Contents of the invention
