Description
Technical field
This utility model is related to boiler technology field, more particularly to boiler afterheat is recycled in the baking of high-moisture biomass
Dry systems.
Background technology
As the world constantly rises to the exploitation demand of new forms of energy, the boiler with biomass as fuel is growing.But it is big
The contained moisture of the biomass of part itself is higher, is unfavorable for carrying out burning utilization.
Utility model content
This utility model is directed to the problems referred to above of the prior art, there is provided high-moisture biomass fuel drying system, its knot
Structure is compact, easy for installation, and operating maintenance is simple, economical, safe and reliable.
The technical scheme adopted by this utility model is as follows：
High-moisture biomass fuel drying system, including drying tank, is provided with feeding device and air inducing at the top of drying tank
Pipe, induced duct are connected with air-introduced machine, and the air outlet of air-introduced machine is communicated with boiler by outlet conduit, and the bottom for drying tank is provided with
Drawing mechanism and air inlet pipe, air inlet pipe are communicated with the air distribution device being installed in drying tank；
Further technical scheme of the present utility model is as follows：
Further, the inwall for drying tank is provided with detection means；
Further, feeding device and drawing mechanism are Starlike valve；
Further, the outlet of air distribution device is cap-like structure.
The utility model has the advantage of：The part high-temperature flue gas drying moisture content that drying system is produced using boiler itself compared with
High biomass circulating is utilized, and the larger economic benefit that improve boiler, while the air outlet blast cap of air-intake device can be effective
Prevent fuel from blocking, it is ensured that the safe handling of equipment.
Description of the drawings
Fig. 1 is arrangement schematic diagram of the present utility model.
Fig. 2 is the enlarged drawing at I in Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings, illustrate specific embodiment of the present utility model.
As depicted in figs. 1 and 2, this utility model includes drying tank 3, and the top for drying tank 3 is provided with feeding device 4 and draws
Airduct 9, induced duct 9 are connected with air-introduced machine 7, and the air outlet of air-introduced machine 7 is communicated with boiler 10 by outlet conduit 8, dry tank 3
Bottom is provided with drawing mechanism 2 and air inlet pipe 1, and air inlet pipe 1 is communicated with the air distribution device 6 being installed in drying tank 3；Preferably,
The inwall of drying tank 3 is provided with detection means 5, and detection means 5 is used for detecting the position of the biomass fuel in drying tank 3, real
When control feeding device 4 charging rate；Preferably, feeding device 4 and drawing mechanism 2 adopt Starlike valve, can be relatively good
Control biomass fuel charging and discharging speed；Preferably, the outlet of air distribution device 6 is cap-like structure, as shown in Fig. 2
Enter fashionable in high-temperature flue gas from air inlet pipe 1, through the distribution of air distribution device 6, flue gas enters drying tank 3 to Gao Shui from multiple outlets
The biomass fuel for dividing is dried, and biomass fuel is also not easy to block the outlet of air distribution device 6, it is ensured that the peace of equipment
Row for the national games；
Operation principle of the present utility model is as follows：
The high-temperature flue gas Jing air inlet pipe 1 that boiler 10 is produced is introduced to dry in tank 3, and from bottom to up biomass fuel is heated
Drying, the biomass fuel of high-moisture are entered at the top of tank 3 by drying, and are then moved from top to bottom, biomass fuel moisture evaporation
Afterwards, discharge from bottom, realize the countercurrent flow of biomass fuel and flue gas, high-temperature flue gas form low temperature after countercurrent flow
Flue gas is discharged by air-introduced machine 7 by induced duct 9 and outlet conduit 8 as the secondary wind of boiler from top, strengthens hearth combustion, shape
Into the recycling of high temperature flue-gas from boiler.
It, to explanation of the present utility model, is not the restriction to utility model that above description is, what this utility model was limited
Scope can make any type of modification referring to claim within protection domain of the present utility model.
