The invention discloses a derivative fuel reverse-flow air cold dryer, comprising a shell arranged with a feeding hopper and a collecting hopper, a negative pressure air outlet at the upper part of the shell, and an air inlet at the lower part of the shell; an unloading impeller is arranged in the feeding hopper, and linked with a reducing motor; the unloading impeller is provided with multiple radial plates; a poly-square conical distributor is arranged in the shell beneath the feeding hopper, and multiple triangular distributing ventilating hole plates are arranged in the shell beneath the distributor at intervals; point parts of the distributor and the triangular distributing ventilating hole plates are arranged upwards, and the triangular distributing ventilating hole plates are provided with multiple venting holes; the air inlet is located beneath the triangular distributing ventilating hole plate. The reverse-flow air cold dryer specific to the derivative granular fuel can realize the closed air type unloading, prevent air leakage, reduce drying energy consumption and cost; meanwhile, the drying efficiency is high, the air cold dryer is not easy to block, and can guarantee normal work of the device.
Description
technical field [0001] The invention relates to an air-cooled dryer, especially a counter-current air-cooled dryer for derived fuels. Background technique [0002] The preparation of derived fuels from biomass or domestic waste is an increasingly used waste utilization treatment method; due to the high water content of the raw materials, the prepared derived fuels need to be dried to reduce moisture; the existing dryers cannot Realizing closed-air unloading will cause air leakage, which will increase energy consumption and cost; at the same time, the mixing and contact between materials and drying air will be uneven and insufficient, the drying efficiency will be low, and blockage will easily occur, making it impossible to guarantee normal operation. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned deficiencies in the prior art, and provide a countercurrent air-cooled dryer for derivative fuel, which can realize clos...
