The utility model relates to the technical field of autoclaved
fly ash green
brick drying, and discloses an autoclaved
fly ash green
brick drying device which comprises a
drying box and a cooling box, a filter
cartridge is fixedly arranged at one end, close to the cooling box, of an
exhaust pipe, a
filter element is embedded in the filter
cartridge, a spiral
copper pipe is installed in the cooling box, and the spiral
copper pipe is fixedly connected with the drying box. According to the
waste gas cooling device, impurities contained in
waste gas are filtered and intercepted through the
filter element firstly, then the
waste gas enters the spiral
copper pipe in the cooling box, cooling water is driven by the
circulating pump to surround the spiral copper pipe, the cooling water is cooled through the cooling water, and the waste gas is cooled through the cooling water. The heated cooling water can flow into the cooler to be cooled, then flows back into the cooling box to be recycled and is conveyed and distributed into the multiple sets of U-shaped hot air pipes through the air distribution pipes, hot air flow is jetted out in multiple directions, it is guaranteed that all the surfaces of each
brick can make contact with hot air in cooperation with the multiple
layers of trays, drying dead corners are avoided, and the drying efficiency is improved.
