Moisture waste heat recycling composite drier

Abstract

The invention discloses a moisture waste heat recycling composite drier which comprises a drying tunnel 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 tunnel section respectively. Hot air generated by the heat source section passes through a hot air duct and flows to the drying tunnel section through dragging of the circulating fan section. A moisture removing waste heat exchanging module is further arranged at the top of the drying tunnel section and comprises two board-type heat exchangers, a mesh drainage board, a water collecting trough and a moisture removing fan. The mesh drainage board is arranged between the two board-type heat exchangers. The moisture removing fan and the water collecting trough are arranged above and below the mesh drainage board respectively. Moisture removing air ducts communicated with the tail end of the drying tunnel section are arranged at two sides of the drying tunnel section. The two board-type heat exchangers are communicated with the moisture removing air ducts and moisture is collected in the mesh drainage board from the two sides. Circulated hot air moisture waste heat is effectively recovered, so that the use rate of fire coal is greatly reduced, the cost for drying agricultural products is reduced and the moisture waste heat recycling composite drier is beneficial to environment protection.

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 [0004] Purpose of ...
