Abstract

A biomass material jet-burning device belongs to the technical field of combustion equipment manufacture. The device adopts a bin, a pusher, a hopper, a material feeding pipe and a fan. The pusher is arranged at the bottom of the bin, the hopper is arranged below the pusher, the bottom of the hopper is communicated with the material feeding pipe, and the tail end of the material feeding pipe is connected with the fan. When being installed, the front end of the material feeding pipe is inserted in a boiler furnace. When the device is operated, the inferior coals are burned in the boiler, the crushed powder biomass materials are thrown into the bin through a material feeding hole of the bin, and the pusher pushes the materials in the bin to the inside of the hopper, the pushed material enters the material feeding pipe, and the fan blows the materials in the material feeding pipe to the boiler furnace through the material feeding pipe. The materials entering the furnace can conduct suspension combustion when meets with open fire due to the wind action, generate instant high calorie, promote the adequate combustion, and enable the calories generated in the boiler to reach the regulated caloric value.

Description

The biomass material air-cone

Technical field:

The utility model belongs to combustion apparatus manufacturing technology field, is a kind of device to the boiler transfer the fuel.

Background technology:

Fuel such as current coal are in short supply, high-quality coal price height, and buy difficulty, the boiler combustion colm does not then reach the heat standard.There are some research institutions to be devoted to develop biomass fuel at present and replace coal, method is to be pressed into particle after biomass material is pulverized, some in addition again particle is made charcoal, though be convenient to transportation and burning like this, but process complexity, and need to consume a large amount of electric energy, production cost is higher than the coal sales price.

Summary of the invention:

The technical problems to be solved in the utility model is to disclose a kind ofly to provide the biomass material air-cone of heat energy to coal-burning boiler, to reach the purpose of utilizing colm to supply with boiler combustion.

The scheme of the utility model technical solution problem is to adopt feed bin, pusher, hopper, feed pipe and blower fan to constitute the biomass material air-cone, charging aperture is arranged at feed bin top, pusher is installed in the feed bin bottom, hopper is below pusher, the bottom of hopper is communicated with feed pipe, and the rear end of feed pipe connects blower fan.During installation the feed pipe front end is inserted in the burner hearth of boiler, can insert by the loud and clear Wang Kou of boiler.Wherein pusher can be spiral pusher, also can be board-like pusher.Colm in the work time point combusting boiler, with the powdery biomass material after pulverizing, as saw the coccoids such as the thin foam of shell of foam, the thin foam of crops leaf bar, nut, and in the charging aperture input feed bin of multiple powdery biomass material mixed material by feed bin, pusher is pushed into the material in the feed bin in the hopper, enter feed pipe then, blower fan is blown into the material in the feed pipe in the burner hearth of boiler by feed pipe.The material that enters burner hearth can produce high heat because the naked light suspension combustion is met in wind action in burner hearth moment, promotes colm to fill a part burning, and the heat that boiler is produced reaches the calorie value of regulation.

Because the caloric value difference of the varying in size of boiler, colm, the calorie value difference that requires boiler to produce, unit interval need provide the amount of material also inequality to burner hearth, in order to control unit interval feeding amount, between hopper and feed pipe, doser is housed, doser is made of housing, rotating shaft and cutting plate, rotating shaft and cutting plate are in housing, and cutting plate is axially fixed in the rotating shaft, evenly distribute radially.By adjusting the speed of rotating shaft, can control the inventory that falls into feed pipe.

Because biomass material is a puffy, may cause the material skewness that enters in the feed bin, agitator is housed in feed bin, the material in the storehouse is evenly distributed, can play mixing purpose more uniformly for multiple powdery biomass material mixed material.

On the feed bin top dust settling pocket is housed, can discharges too much air in the feed bin, prevent that simultaneously the material fine powder from overflowing.

Be with the intensification sleeve pipe outside feed pipe, the intensification sleeve pipe connects the smoke exhaust pipe of boiler, and hot flue gas is through sleeve pipe, can be with the air heat in the feed pipe, thereby making the gas that enters boiler is hot-air, increases combustion heat value, necessary more for the Winter heat supply boiler.

The utility model the biomass fuel carried to boiler fire box temperature is improved rapidly, the soft coal that burning-point is higher, calorific value is lower is fully burnt, after-flame, combustion are thoroughly, the sulfide and the nitride that generate in the biomass fuel combustion process are less, meet the national environmental protection industrial policy, and greatly reduced sulfur corrosion to boiler body equipment, improved the service life of equipment, energy-saving effect is remarkable, and the thermal efficiency improves more than 10%, and the burning cost is lower than common bituminous coal, simple in structure, compact, floor space is little, and is stable, and cost is low.

Fig. 2 is board-like pusher schematic diagram.

The specific embodiment:

Example 1, the utility model is by feed bin 1, pusher 2, hopper 3, feed pipe 4 and blower fan 5 constitute, charging aperture 12 is arranged at feed bin 1 top, pusher 2 is installed in feed bin 1 bottom, hopper 3 is below pusher 2, between hopper 3 and the feed pipe 4 doser 6 is housed, doser 6 is by housing 7, rotating shaft 8 and cutting plate 9 constitute, rotating shaft 8 and cutting plate 9 are in housing 7, cutting plate 9 is axially fixed in the rotating shaft 8, evenly distributes radially, and the bottom of housing 7 is communicated with feed pipe 4, the rear end of feed pipe 4 connects blower fan 5, agitator 10 is housed in feed bin 1, on feed bin 1 top dust settling pocket 11 is housed, wherein pusher 2 is spiral pushers.

Example 2, other content are with example 1, and pusher 2 is board-like pushers, are made of driving shaft 13, driven shaft 14, driving-belt 15 and push pedal 16, and driving-belt 15 is centered around driving shaft 13 and driven shaft 14 places, and push pedal 16 is vertically fixed on the driving-belt 15, and evenly distribute.
