It falls in water and is removed, lesser dust particles are truly realized smokeless ashless effect by helping flow fan to be discharged through sewage draining exit 43
Fruit reaches dedusting and environmentally friendly purpose.In addition, flow fan is helped flue gas flow rate can be made to accelerate, quickly flows out in deduster 4 and carry out
Filtering, so that it is guaranteed that burner hearth 2 burns sufficiently, there is no a large amount of flue gases to hinder fuel combustion.Water in deduster 4 then passes through
Sewage pipe 44 is discharged, opening and end by 45 control of sewage disposal pipe 44 of blowdown valve.
The feed inlet of fire box 11 is connected with feed screw 5, and feed screw 5 includes feeding screw 51, is set to feeding spiral shell
It revolves the sprocket wheel 52 of 51 ends and the fuel hopper 53 set on 51 upside of feeding screw, feeding screw 51 connects the charging of fire box 11
Mouthful；The inside of fire box 11 is equipped with fireguard 111, and feeding screw 51 is connected at fireguard 111.Wherein, fuel hopper 53 is for containing
Biomass fuel or other fuel are filled, feeding screw 51, the middle part of feeding screw 51 are delivered fuel to by rotating sprocket 52
Equipped with helical axis, for driving feeding screw 51 to rotate, and then fuel is rotated to the feed inlet for being pushed out to fire box 11, and along fire box
11 fall in burner hearth 2.Since the delivery end of feeding screw 51 is located at fireguard 111, so that fuel is in combustion not
It can be tempered in fuel hopper 53, to improve the service life of feed screw 5, reduce economic loss.
Feeding screw 51 is sheathed in spiral duct 6, and the feed inlet of one end connection fire box 11 of spiral duct 6, spiral is led
One end of the downside connection spiral cooling duct 61 of pipe 6, the other end of spiral cooling duct 61 connect combustion fan, combustion fan
The lower section side of burner hearth 2 is connected through combustion fan connector 7.In the present embodiment, the air outlet of combustion fan is through spiral cooling wind
Pipe 61 connects fire box 11, influences burner hearth 2 by the high temperature of fire box 11, it is ensured that burner hearth 2 does not damage permanently, improves
On the other hand the service life of burner hearth 2 improves the temperature of fire box 11, and then transmit heat from level to level, improve the thermal efficiency.
Burner hearth 2 is tapered, and the conical section of burner hearth 2 includes a long side and a short side, and the angle of long side and horizontal plane is
30 °, the angle of short side and horizontal plane is 40 °.The pyramidal structure can quickly be recovered to the heat of bottom in fire box 11, save
Recovery time, heat recovery rate is up to 80%, when coal-fired or combustion bavin, may make Coal-fired capacity to save 30%, combustion bavin amount saves 40%.Furnace
The outer wall of thorax 2 is sieve-board type structure, and the structure is identical as the sieve-plate structure of sieve-board type heat exchanger plates 13, and conical screen plank frame can make
Burner hearth 2 heats not cutoff fastly, thoroughly solve coal, bavin cutoff, cooling, the problems such as need to manually roasting in charging.Burner hearth 2
Lower part connect grate 21, the lower end of grate 21 is equipped with heat recovery hole 211, and the waste heat for generating 2 surrounding of burner hearth recycles
To burner hearth 2, so that the fire quickly flowing in burner hearth 2, fuel combustion is more abundant, and furnace temperature is quickly enhanced about more than once, and saves
The energy and fuel.The top of grate 21 is equipped with fire hole 22, for lighting fuel.
The two sides of sieve-board type heat exchanger plates 13 are symmetrically arranged with the hot-blast outlet 7 of connection 11 outer wall of fire box,；It is with 11 bottom of fire box
Circumference is placed with cold wind import 8 on 15 bottom surface of furnace shell on boundary.The outside of burner hearth 2 is furnace shell 15, and the lower part side of furnace shell 15 is equipped with
Ash hole 9, for the slag generated after fuel combustion ash to be discharged.In the present embodiment, furnace shell 15 is with the junction of fire box 11 and burner hearth 2
It is divided into upper furnace shell 151 and lower furnace shell 152 for boundary, the width of upper furnace shell 151 is greater than lower furnace shell 152, circle on the bottom surface of upper furnace shell 151
It is placed with cold wind import 8 week, when furnace body 1 is stopped using, 8 fast cooling of cold wind import can be passed through；Two hot-blast outlets 7 can add
It is fast cooling.
The working process of this embodiment is as follows: fuel is placed in fuel hopper 62, is delivered to fire box 11 through feed screw 6
It is interior, fuel is lighted by fire hole 22, so that full combustion of fuel, flare is spread at fire box 2, and fire box 2 is by heat through sieve plate
The sieve pore of formula heat exchanger plates 13 transfers heat to heat-conducting plate 14, the heat of generation through heat-conducting plate 14 be transferred to heat-conducting plate 14 and furnace shell 15 it
Between, then pass through heat air inlet 31 and concentrated on around fire box 11 again through sieve-board type air intake plate 32, so that temperature equalization；Fuel
The flue gas generated that burns enters in eight flue connecting tubes 12 from different location, then is delivered to flue gas by flue outlet pipe 121
In deduster 4, so that contained biggish dust particles fall in water and are removed in flue gas, lesser dust particles are by helping stream wind
Machine is handled through the discharge of sewage draining exit 43；In combustion, the waste heat that 2 surrounding of burner hearth generates can be recycled in real time in burner hearth 2,
So that quickly flowing, fuel combustion are more abundant for the fire in burner hearth 2；In addition, combustion fan intermittent can pass through spiral cooling wind
Pipe 61 cools down fire box 11, so that burner hearth 2 is not influenced by the high temperature of fire box 11, it is ensured that burner hearth 2 does not damage permanently, goes forward side by side
One step improves the thermal efficiency.The heat recovery rate of the present embodiment is up to 80%, if coal-fired, Chai Shi, so that Coal-fired capacity saves 30%, fires bavin amount
The features such as saving 40%, thoroughly realizing without dead angle, noncoking, few ashes.
The present embodiment work when, 20 DEG C or so can be heated per minute, maximum temperature up to 250 DEG C, and temperature-controlled precision be ±
0.2 DEG C, it is suitable for drying tealeaves, medicinal material, food, paddy etc., and regardless of selecting the fuel such as biomass or coal, diesel oil, all
High-efficiency environment friendly can be reached, the advantages that low-carbon low consumption is low in cost, long service life.
