Description

A kind of novel biomass counter-burning type hot-water boiler

Technical field

The present invention relates to a kind of biomass thermal homogeneous solution-type reactor, particularly novel biomass counter-burning type hot-water boiler.

Background technology

The boiler that utilizes the biomass moulding briquetting to make fuel is not at present popularized in market as yet; And the combustion technology of existing boiler is more backward; Be that combustion air just gets into from the grate of burner hearth bottom surface; Fuel on the grate, ash cover on the grate face, and the grate improper ventilation is not enough to the fuel combustion oxygen supply.The thermal efficiency of this boiler is low, dust is serious, fume emission is more.Therefore, the structure of design novel biomass boiler, it is imperative to develop new combustion technology.

The counter-burning type hot-water boiler is a kind of hot-water boiler at present commonly used, and counter-burning type boiler and biomass fuel combine have the higher thermal efficiency, smoke discharge amount is still less.It comprises two burner hearths up and down that separate through fire grate, in upper furnace, does not have the fuel of completing combustion to fall into lower hearth through fire grate and burns away, thereby make burning more complete, and fuel availability is improved, and has reduced the discharging of harmful smoke simultaneously.

Existing anti-burn stove because structure inadequately rationally service life shorter, complex operation is complicated and then influenced the normal use of hot-water boiler.On the other hand, the boiler chimney discharged flue gas carries great amount of heat energy, directly is discharged into and not only causes energy waste in the atmosphere, and destroy the earth atmosphere environment.The patent application of Chinese patent specification 200910015495.4 discloses a kind of vertical counter-burning coal-fired hot water boiler, and this boiler design has unique heat exchange water-cooled wall, complex structure; Cost of manufacture is higher, and dust is serious on the water-cooling wall, the deashing difficulty; Service life is shorter, the boiler attendance difficulty.The patent application of Chinese patent specification 200820174280.8 discloses a kind of novel counter-burning type hot-water boiler; The anti-burning furnace wall of this boiler design is made up of two arcs; To compare the furnace volume proportion less with whole boiler, need during boiler operatiopn frequent reinforced, complex operation.

Summary of the invention

To above deficiency; The object of the present invention is to provide a kind of novel biomass counter-burning type hot-water boiler; Be that biomass block fuel is directly joined in the upper furnace from the roof of the furnace charge door, fuel is realized autofeed under the effect of gravity and air-introduced machine, and flue gas passes through boiled water tank and reservoir inner chamber successively; Carry out getting into flue gas cleaner behind the multi-stage heat exchanger, enter the atmosphere from chimney at last.It has the advantage of sufficient combustion, thermal efficiency height and energy-conserving and environment-protective.

Technical scheme of the present invention realizes in the following manner: a kind of novel biomass counter-burning type hot-water boiler; Comprise boiler body; Be provided with the boiler water interlayer at the boiler body inner chamber, be divided into upper furnace and lower hearth; Separate with upper fire-grating, the lower hearth below is provided with dust collection chamber, between lower hearth and dust collection chamber, is provided with lower fire grating; The positive basifacial of body of heater is provided with air door and ash hole; It is characterized in that: the sidewall of described lower hearth is provided with smokejack and is communicated with the boiled water tank inner chamber, and the inner chamber of boiled water tank is connected as flue with the inner chamber of reservoir through connecting pipeline, boiled water tank smokejack, and the exhaust opening that is provided with of reservoir upper end is connected to chimney through pipeline and air-introduced machine.

Described upper furnace passes straight through to the boiler body top and communicates with the external world, and air inlet is all charging aperture.

Described boiled water tank inner chamber is provided with many horizontal rows to heat exchange water pipe group; Laterally heat exchange water pipe group two ends are communicated with the boiled water tank water interlayer respectively.

Described reservoir inner chamber is provided with a smoke baffle plate, vertically inner chamber is separated into two spaces.

Described reservoir inner chamber also is provided with horizontal heat exchange water pipe group and crosses smoke baffle plate, and two ends are communicated with the reservoir water interlayer respectively.

Described reservoir epicoele exhaust opening place is provided with flue gas cleaner and built-in high efficiency filter material, and its flue gas cleaner lower end and reservoir exhaust opening place are equipped with separation net.

Novel biomass counter-burning type hot-water boiler of the present invention, charging aperture joins in the upper furnace biomass block fuel from top.Hot fuel during boiler operatiopn on the upper fire-grating and unburnt particulate under air-introduced machine and gravity effect, drop downwards while burn, and drop on the lower fire grating, and imperfect combustion fuel particle burns away, and the soot particle of after-flame falls into dust collection chamber from lower fire grating.Flue gas gets into the boiled water tank inner chamber by the lower hearth smokejack, passes from heat exchange water pipe group internal clearance, gets into reservoir by the boiled water tank smokejack again; Flue gas passes the inner gap of heat exchange water pipe group and gets into flue gas cleaner under the guiding of reservoir inner chamber smoke baffle plate, handle the back through evolving and discharge from the exhaust opening of reservoir, gets into chimney through air-introduced machine.

Novel biomass counter-burning type hot-water boiler provided by the invention compared with prior art has following advantage: one, adopted the technical scheme of second-time burning according to the burning feature of biomass molding fuel, therefore had the characteristics of sufficient combustion, good environmental protection; Two, the boiler furnace design is unique, in limited space, designs bigger burner hearth area, and efficiency of combustion is higher.Boiler design is last feed type, and air inlet and charging aperture unite two into one, and directly charge door joins in the upper furnace biomass block fuel from top, and fuel is realized autofeed under the effect of gravity and air-introduced machine, and once reinforced can the operation for more time saved manpower.Three, the flue gas of boiler emission passes through boiled water tank and reservoir inner chamber successively; Enter the atmosphere from chimney at last; And the heat that the horizontal heat exchange water pipe group of boiled water tank and reservoir inner chamber is collected adds in the boiler heat exchange aqueous system through hot water; Make full use of boiler afterheat, improved the thermal efficiency of boiler.Four, boiler exhaust gas mouth place is provided with flue gas cleaner, but tar in the effective elimination flue gas and ash content, and pollutant emission is well below national standard.
