Spiral force can convey fuel by the spiral force, furthermore it is possible to by the stirring of of thin bar 214 itself, fuel be allowed to become
It obtains loosely, it is more uniform to be contacted with air, to make the mixing of fuel and air more uniform, and then fired in subsequent control
When burning, it is only necessary to control the feed speed of fuel, and burn and more stablize, control is more accurate.
As shown in figure 3, feed mechanism 23 includes Material disintegrator 231 and screw rod conveyor 232, fuel is passed through into Material disintegrator 231
It is smashed, is then delivered fuel in feed pipe 21 by screw rod conveyor 232.Baking to fuel for convenience, allows
Its internal moisture content is detached from, and the appearance of screw rod conveyor 232 is provided with casing layer 233, and a constant temperature is inputted in casing layer 233
It can be heated to the surface of screw rod conveyor 232, and then screw rod conveyor 232 can be allowed to convey for the air of degree
It is heated when fuel, and then the moisture content in fuel can be evaporated, to make fuel more dry.
Fuel conveying control machine is arranged in control to fuel for convenience between screw rod conveyor 232 and feed pipe 21
Structure 24, as shown in Figure 3 and Figure 4, the mechanism include for being connected to the casing 241 of screw rod conveyor 232 and feed pipe 21, being mounted on
Impeller 242 in casing 241 for broadcasting fuel and the actuator 243 for driving impeller 242 to rotate, wherein actuator
243 are constituted using driving motor, by controlling the rotating speed of driving motor, reach the rotating speed of control impeller 242, and then defeated in screw rod
In the case of sending the conveying of machine 232 more sufficient, make fuel conveying more stable, and control can be facilitated.In order to make screw rod defeated
Sending the fuel between machine 232 and fuel conveying and controlling mechanism 24 to supply can be into row buffering, and then storaging bucket is provided between
25, the fuel conveying and controlling mechanism 24 is arranged in the bottom of storaging bucket 25, and casing 241 is allowed to be connected to 25 inside of storaging bucket, to
It can carry out conveying fuel.The fuel of conveying is imported into storaging bucket 25 by screw rod conveyor 232.In storaging bucket 25 and casing
241 are arranged with shell 26 in appearance, and form space for gas to pass through, and interlayer pipe 211 is allowed to be connected to the space,
And then fuel can be allowed to keep more stable temperature during entire conveying.The top of storaging bucket 25 is provided with escape pipe
251, escape pipe 251 can will be exported in fuel by the steam at heating evaporation.
Referring to Fig.1 and Fig. 6, it is both provided with temperature sensor in feed pipe 21, interlayer pipe 211 and casing layer 233
271, for detecting internal temperature, temperature sensor 271 is installed in storaging bucket 25, the temperature for detecting temporary fuel
Degree.It is connected with cold air pipe 28 in steam line 22, is mixed with the hot-air in steam line 22 by cold air pipe 28,
And then the air of temperature required for it can be formed, wherein being respectively arranged on steam line 22 and on cold air pipe 28
First control valve 272 and the second control valve 273, and the first control valve 272 and the second control valve 273 are all made of solenoid valve composition,
By the way that the aperture of the first control valve 272 and the second control valve 273 to be adjusted, to adjust the ratio of cold air and hot-air
Example achievees the purpose that control temperature.First control valve 272 and the second control valve 273 are provided with the control of controller 274, controller
274 may be used CPU, PLC or processor composition, and controller 274 receives the above-mentioned temperature sensor 271 being arranged everywhere
Temperature signal（Subject to the main temperature using 21 fuel of feed pipe）, and control the aperture and the of the first control valve 272
The aperture of two control valves 273.
As shown in figure 5, being all made of bolt between interlayer pipe 211 and feed pipe 21 and between interlayer pipe 211 and shell 26
It is tightly connected, when air hole 212 blocks, interlayer pipe 211 can be unclamped, will be breathed freely by iron wire or other rod-like structures
Hole 212 is dredged.
After fuel is sent into boiler 1, by igniter 3 by ignited fuel, burns, filled finally by vent gas treatment
It sets the tail gas that 4 pairs of burnings generate to handle, since the exhaust temperature after burning is higher, on the one hand discharge can allow the temperature of environment
It increases, is on the other hand also the waste to the energy.Therefore, steam line 22 and exhaust gas processing device 4 are exchanged heat, to allow
The temperature of tail gas decreases.
As shown in Figure 1, exhaust gas processing device 4 includes the offgas duct 41 being connect with boiler 1, it can be by tail gas out of boiler 1
Export.Cyclone separator 42, heat exchanger 43, deduster 44 and treating column 45 are respectively arranged in offgas duct 41.Tail gas is first
It enters cyclone separator 42 out of offgas duct 41 to be removed the impurity in tail gas, and then the solid impurity in follow-up tail gas
It is less.It is further conveyed after cyclone separator 42 in tail gas, is exchanged heat at this time by heat exchanger 43, reduce tail gas
Temperature, and be dusted after heat exchange and other processing, allow tail gas that can reach discharge standard.
Wherein, as shown in Figure 1,42 bottom of cyclone separator is provided with ash ejector 46, cyclone separator 42 is separated
Dust be discharged, and due to inside many times cyclone separator 42 there are bigger pressure, in the mistake of ash discharge
