Description of the drawings
Fig. 1 is the structural representation of the biomass material drying system that tail gas of the present invention is reclaimed entirely.
Specific embodiment
Present pre-ferred embodiments are given below in conjunction with the accompanying drawings, to describe technical scheme in detail.
The biomass material drying system that the tail gas of the present invention is reclaimed entirely is by waste-heat feed bin 101, waste-heat feeding
The tubulation heated drums main frame 104, gas-solid separator of machine 102, the feed screw 103, container-type with closed structure
107th, the circulating fan 106 of high-seal, secondary heater 105, spiral discharging machine 108, the height of afterheat steam pipe 109, main frame
Warm tubulation 110 and hot water pipeline 111 are constituted, and waste-heat feed bin 101 is by waste-heat feeder 102 and carries closed structure
Feed screw 103 connect, hot water pipeline 111 be located at waste-heat feed bin 101 below, the tubulation heated drums of container-type
Main frame 104 is located at the lower section of secondary heater 105, the tubulation heated drums main frame of the high temperature tubulation 110 of main frame in container-type
104 sides, secondary heater 105 are located at the top outside 110 container of high temperature tubulation of main frame, the circulating fan of high-seal
106 sides for being located at the outer secondary heater 105 of container, spiral discharging machine 108 are used to connect gas-solid separator 107 and packaging
Case, one end of afterheat steam pipe 109 are connected with gas-solid separator 107, the other end and the waste-heat feeding of afterheat steam pipe 109
Machine 102 connects.
The thermal source that the machine is adopted can be biomass fuel, it is also possible to natural gas, superheated steam, oil, electricity etc..
What biomass material drying system was discharged is liquid condensation water, due to without heat of evaporation（Evaporating moisture needs
Heat of evaporation）, the heat only required for material temperature rise, thus energy consumption relatively at present routine drying system energy-conservation 2/3rds with
