Background technology
Existing current biomass material is dried, and all adopts Hot-blast Heating material or is dried by conduction oil, steam indirect material, the water vapour that material drying produces, by discharging after exhaust gas cleaner purification.
Producing a large amount of water vapour owing to drying, is taken out of by gas, can with dust, and some materials also have various bad air and discharge, and when purifier is not in place, impact to environment.
Current biomass material drying system, all can have large tail water steam to discharge, and when being cold outside, having a large amount of white mist and produces.Although be a large amount of water vapours and a small amount of dust, but people around can be caused to misread, often can produce contradiction and dispute.
In addition, current biomass material drying system, because of containing a large amount of oxygen, living beings in the case of a high temperature, very easily produce the risk of catching fire, exploding.
Moreover current biomass material drying system, drying moisture needs a large amount of heat of evaporation, and energy consumption is high, makes oven dry less economical.
Summary of the invention

The present invention solves above-mentioned technical problem by following technical proposals: the biomass material drying system that a kind of tail gas reclaims entirely, it is characterized in that, it is made up of the high temperature tubulation of the circulating fan of waste-heat feed bin, waste-heat feeder, tubulation heated drums main frame with the feed screw of closed structure, container-type, gas-solid separator, high-seal, secondary heater, spiral discharging machine, afterheat steam pipe, main frame and hot water pipeline, waste-heat feed bin is connected with the feed screw with closed structure by waste-heat feeder, hot water pipeline is positioned at below waste-heat feed bin, the tubulation heated drums main frame of container-type is positioned at the below of secondary heater, the high temperature tubulation of main frame is in the tubulation heated drums main frame side of container-type, secondary heater is positioned at the top outside the high temperature tubulation container of main frame, the circulating fan of high-seal is positioned at the side of the outer secondary heater of container, spiral discharging machine is for connecting gas-solid separator and container, one end of afterheat steam pipe is connected with gas-solid separator, the other end of afterheat steam pipe is connected with waste-heat feeder.
Preferably, the biomass material drying system that described tail gas reclaims entirely adopts the full recovery technology of tail gas.
Preferably, what the biomass material drying system that described tail gas reclaims entirely was discharged is liquid condensation water.
Preferably, the biomass material drying system that described tail gas reclaims entirely adopts the tubulation heated drums main frame of container-type.
Preferably, the biomass material drying system that described tail gas reclaims entirely heats in the rotating cylinder inside of container-type.
Preferably, the biomass material drying system that described tail gas reclaims entirely adopts container-type, modularized design.
Positive progressive effect of the present invention is: the present invention does not have toxic emission completely, energy-conservation, and heat loss is few.
Accompanying drawing explanation
Fig. 1 is the structural representation of the biomass material drying system that tail gas of the present invention reclaims entirely.
Detailed description of the invention
Present pre-ferred embodiments is provided, to describe technical scheme of the present invention in detail below in conjunction with accompanying drawing.
The biomass material drying system that tail gas of the present invention reclaims entirely is by waste-heat feed bin 101, waste-heat feeder 102, with the feed screw 103 of closed structure, the tubulation heated drums main frame 104 of container-type, gas-solid separator 107, the circulating fan 106 of high-seal, secondary heater 105, spiral discharging machine 108, afterheat steam pipe 109, high temperature tubulation 110 and the hot water pipeline 111 of main frame form, waste-heat feed bin 101 is connected with the feed screw 103 with closed structure by waste-heat feeder 102, hot water pipeline 111 is positioned at below waste-heat feed bin 101, the tubulation heated drums main frame 104 of container-type is positioned at the below of secondary heater 105, the high temperature tubulation 110 of main frame is in tubulation heated drums main frame 104 side of container-type, secondary heater 105 is positioned at the top outside high temperature tubulation 110 container of main frame, the circulating fan 106 of high-seal is positioned at the side of the outer secondary heater 105 of container, spiral discharging machine 108 is for connecting gas-solid separator 107 and container, one end of afterheat steam pipe 109 is connected with gas-solid separator 107, the other end of afterheat steam pipe 109 is connected with waste-heat feeder 102.
The thermal source that the machine adopts can be biomass fuel, also can natural gas, superheated steam, oil, electricity etc.
What biomass material drying system was discharged is liquid condensation water, due to without heat of evaporation (i.e. transpiring moisture need heat of evaporation), only has the heat required for material temperature rise, therefore the more current conventional drying system energy-conservation more than 2/3rds of energy consumption, especially high moisture material, energy-saving effect is especially obvious.
As shown in Figure 1, the feed screw 103 of drying main frame delivered to by wet stock by the feeder 102 under feed bin 101, deliver in the tubulation heated drums main frame 104 of container-type by feed screw 103, heated by high temperature tubulation 110 pairs of materials of main frame, and simultaneously to the steam heating that material produces, material after oven dry is in the rear portion discharging of rotating cylinder, and through spiral discharging machine 108 discharging, some thin materials are via gas-solid separator 107 discharging below; The water vapour (tail gas) that material drying produces is delivered to secondary heater 105 by blower fan 106 and is heated, after heating, become high-temperature steam entered by rotating cylinder feed end, wet stock is heated, and to the heating tubulation 110 in rotating cylinder together with material, then heat.The excess steam that drying materials produces carries out preheating by afterheat steam pipeline 109 to the feeder at gas-solid separator top to wet stock, and the hot water produced after steam-condensation to be heated preheating to wet stock stockyard by hot water pipeline 111 again.
The above specific embodiment; the technical problem of solution of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
