Technical field
It take living beings as the biomass combustion device of fuel that the utility model relates to a kind of, sprays in the burner hearth of boiler for docking with boiler furnace by the flame that biomass combustion produces, and belongs to combustion apparatus.
Background technology
At present, Chinese Enterprises adopts traditional coal-burning boiler mostly, and containing a large amount of harmful substance in coal combustion flue gas.Due to the purified treatment high cost of coal-fired flue-gas, still have the coal-burning boiler of a lot of medium-sized and small enterprises because of environmental protection facility imperfection at present, coal-fired flue-gas discharge index is difficult to up to standard, thus causes severe contamination to environment.On the other hand, produce a large amount of discarded living beings such as stem, leaf, grass, root because of difficulty and ward off Processes For Effective Conversion in agricultural production, the phenomenon of " burning the grass on waste land " of the farmland after annual results is seen everywhere.In recent years, succeeding in developing with discarded living beings granular form fuel, as replaced coal to be used for boiler oil living beings, the pollution of coal-fired flue-gas can be avoided, but the existing coal-burning boiler of enterprise changes and burns biomass fuel and remain in problems.
Summary of the invention
The purpose of this utility model is to provide the biomass combustion device that one take the living beings of shaping (granular pattern) as fuel, it can dock with traditional boiler, and the flame that biomass combustion produces is sprayed in the burner hearth of traditional boiler, make traditional coal-burning boiler be converted into biomass combustion furnace.
The utility model biomass combustion device, comprise combustion chamber and ventilating system, combustion chamber is provided with charge door, is provided with fire grate and grey thorax below combustion chamber, and described combustion chamber is provided with the spit tube that can be connected with external boiler; Described spit tube comprises inside and outside two-layer, and inside and outside two-layer between form annular chamber, spit tube internal layer is distributed with fumarole; Described ventilating system comprises the air blast, draught distributing box and the aid distributing pipe that are connected successively, and described aid distributing pipe comprises takes over combustion chamber, grey thorax and flame the many aid distributing pipes be connected respectively by draught distributing box.
The charge door of described combustion chamber is connected with an auger pipe, and auger pipe drives the charge door feeding to combustion chamber by motor.
Described auger pipe top is connected with hopper.
Aid distributing pipe is connected with between described auger pipe end and draught distributing box.
Be provided with lighting-up tuyere and door thereof above the fire grate of described combustion chamber, grey thorax is provided with cleaning door and door thereof.
Described air blast is connected with circuit with a controller with auger pipe motor, and the two is respectively by this controller adjusting rotary speed.
This biomass combustion device to dock with the burner hearth of traditional coal-burning boiler by flame adapter and uses.Biomass combustion device is by the reasonable wind distribution of many aid distributing pipes, biomass fuel is made to be able to Thorough combustion, reach the object of clean burning, the high-temperature flue gas (i.e. flame) produced is sprayed by spit tube and enters in the burner hearth of boiler (i.e. original coal-burning boiler), namely in original coal-burning boiler burner hearth without the need to adding coal or any fuel, and can normally produce water vapour and hot water by means of biomass combustion device, reach with this and substitute with living beings the object that coal is fuel, not only save coal resource, and avoid the discharge of a large amount of harmful components in fire coal, discharge index is made to reach environmental protection standard requirement.Adopt this biomass fuel burning device structure simple, low cost of manufacture and efficiency of combustion is high, respond well.By it and traditional coal-burning boiler with the use of, without the need to transforming this body structure of coal-burning boiler, thus solving a difficult problem for coal-fired boiler reform, reducing improvement cost, simultaneously for energy-saving and emission-reduction contribute.Be particularly suitable for the transformation of the existing middle and small burn coal boiler energy-saving and emission-reduction of unit such as enterprise, cause, bathing place.

Detailed description of the invention
Accompanying drawing is the example structure schematic diagram of the utility model biomass combustion device.The structure of the present embodiment biomass combustion device is described below in conjunction with accompanying drawing.
As Fig. 1, the bottom, combustion chamber 1 of this biomass combustion device is provided with fire grate 7 and grey thorax 8, and grey thorax 8 arranges cleaning door and door 9 thereof.Auger pipe 16 lower end (i.e. top) is connected with variable speed electric motors, particularly, and the charging aperture of combustion chamber 1 is inserted in auger pipe upper end (i.e. end), and auger pipe 16 is connected with hopper 17, auger pipe 16 variable speed electric motors, particularly 15 drive under, with spiral feeding manner to combustion chamber 1 feeding.Be provided with lighting-up tuyere 2 above the fire grate 7 of combustion chamber 1 and be provided with door, the right side of combustion chamber 1 is provided with spit tube, and it is made up of the outer 3-1 of spit tube internal layer 3-2 and spit tube, inside and outside two-layer between form annular chamber 5, spit tube internal layer 3-2 is distributed with fumarole 4.Air blast 14, draught distributing box 12 and each aid distributing pipe constitute ventilating system; Wherein be connected with combustion chamber aid distributing pipe 11 between draught distributing box 12 and combustion chamber 1, between draught distributing box 12 and grey thorax 8, be connected with grey thorax aid distributing pipe 10, be connected with auger aid distributing pipe 13 between the end of draught distributing box 12 and auger pipe 16, between the annular chamber 5 of draught distributing box 12 and spit tube, be connected with flame aid distributing pipe 6.Controller 18 is connected respectively by circuit with between variable speed electric motors, particularly 15 and air blast 14, can control operation or the stoppage in transit of variable speed electric motors, particularly 15 and air blast 14 according to ignition temperature change.Fig. 1 represents, this biomass combustion device is connected by the burner hearth wall of spit tube with external boiler (traditional coal-burning boiler) 19.
During the work of this biomass combustion device, first in hopper 17, add biomass molding fuel, in combustion chamber 1, add some fuel woods by lighting-up tuyere 2 simultaneously, then fuel wood is lighted; Close the door of lighting-up tuyere 2 and the door of cleaning door 9.Start-up connector 18 afterwards, regulates the rotating speed of variable speed electric motors, particularly 15; By auger pipe 16, biomass molding fuel is delivered in combustion chamber 1; Regulate air blast 14 rotating speed, air feed in draught distributing box 12.By combustion chamber aid distributing pipe 11, flame aid distributing pipe 6, grey thorax aid distributing pipe 10 and auger aid distributing pipe 13 respectively in combustion chamber 1, in spit tube (through annular chamber 5), in grey thorax 8 and auger pipe 16(end) in air feed.Along with constantly adding of each road air distribution and biomass fuel, in combustion chamber 1, firepower is strengthened gradually, and combustion position is good.Under the effect of fumarole 4 jet-stream wind, the high-temperature flue gas that biomass combustion generates is to the flowing of spit tube direction, and by spit tube to flame (see Fig. 1 direction of arrow) in the burner hearth of boiler 19, the fire box temperature commendable increase of boiler 19, starts working.According to the change of ignition temperature, controller 18 automatically controls the operation of variable speed electric motors, particularly 15 and air blast 14 or stops in good time, makes stove boiler 19 maintain normal duty, produces steam and hot water.The ash content produced in burning can open the door of cleaning door 9, is disposed by ash.
