A kind of blowing system of biomass boiler
Technical field
The utility model relates to biomass boiler technical field, particularly a kind of blowing system of biomass boiler.
Background technology
Biomass boiler is a kind of biomass boiler, be exactly with biomass energy as the boiler of fuel biomass boiler, be divided into biomass steam boiler, biomass hot water boiler, biomass thermal wind furnace, biomass heat-conduction oil oven, vertical type biomass boiler, horizontal biomass boiler etc.
At present, the blowing system of biomass boiler is dry from bottom to top (path of namely for once drying), oxygen in air near the entrance of combustion chamber for biomass fuel combustion-supporting time almost exhaust, and biomass fuel can produce a large amount of flammable volatile matters after combustion chambers burn enters top, combustion chamber (burner hearth), at this moment the oxygen wretched insufficiency in burner hearth, make flammable volatile matter cannot Thorough combustion, cause energy waste on the one hand, cause emission gases to the pollution of air on the other hand.
Because burning develops gradually after coal powder ignition, burning institute liberated heat is greater than heat output, so flue-gas temperature constantly raises, thus forms a region that burning is rapid, temperature is higher.Heat is released at most in the region.This region of usual title is flame kernel (or combustion centre).The center of combustion centre often bias combustion room, can cause being heated of reservoir chamber uneven in a combustion chamber, and the uneven efficiency of combustion that can reduce combustion chamber of burning.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of blowing system of biomass boiler is provided, boiler furnace is carried out to the air distribution of angle adjustable, in combustion chamber, form whirlwind runner, realize homogenous combustion, thus improve efficiency of combustion.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of blowing system of biomass boiler, comprise boiler body, it is deslagging chamber bottom boiler body, above deslagging chamber is combustion chamber, above combustion chamber is reservoir chamber, and described combustion chamber is provided with the exhaust gases passes for being vented, and described reservoir chamber is provided with water inlet and delivery port; Be provided with blowing system in described combustion chamber, this blowing system comprises air distribution pipeline, deduster and blower fan; Be provided with the some heat energy detectors whole combustion chamber being carried out to heat energy monitoring in described combustion chamber, be provided with a processor and this heat energy detector and blower fan and be electrically connected; Described air distribution pipeline comprises the main pipeline arranged round Inner Wall of Combustion Chamber and the secondary pipeline be communicated with this main pipeline, and the end of this pipeline is communicated with air distribution mouth by angle demodulator, the adjustable angle of air distribution mouth.
In technique scheme, described air distribution pipeline is double-deck setting.
In technique scheme, the bottom of described deslagging chamber is provided with valve.
In technique scheme, described heat energy detector is distributed in the bottom of described combustion chamber.
The beneficial effects of the utility model are: overall structure is simple and compact, blowing system is the air distribution pipeline of adjustable angle and the real-time heat energy distribution detected in combustion chamber, thus by processor adjusting angle adjuster, enable air distribution mouth carry out air distribution adjustment with the burning of bias combustion room combustion centre in time, make to realize homogenous combustion in whole combustion chamber.Maximum temperature point in the combustion chamber detected with heat energy detector is combustion centre (be generally and differ great with average temperature distribution), with this combustion centre for forming the center of whirlwind runner, with the certain distance of this combustion centre for radius forms runner circle, the angle adjustment of air distribution mouth is tangent with this runner circle.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, 3, a kind of blowing system of biomass boiler, comprise boiler body 1, it is deslagging chamber 2 bottom boiler body 1, above deslagging chamber 2 is combustion chamber 3, above combustion chamber 3 is reservoir chamber 4, and described combustion chamber 3 is provided with the exhaust gases passes 5 for being vented, and described reservoir chamber 4 is provided with water inlet 6 and delivery port 7; Be provided with blowing system in described combustion chamber 3, this blowing system comprises air distribution pipeline 8, deduster 9 and blower fan 10; Be provided with the some heat energy detectors 12 whole combustion chamber 3 being carried out to heat energy monitoring in described combustion chamber 3, be provided with a processor and this heat energy detector 12 and blower fan 10 and be electrically connected; Described air distribution pipeline 8 comprises the main pipeline 81 arranged round combustion chamber 3 inwall and the secondary pipeline 82 be communicated with this main pipeline 81, and the end of this pipeline 82 is communicated with air distribution mouth 84 by angle demodulator 83, the adjustable angle of air distribution mouth 84.
Wherein, described air distribution pipeline 8 is double-deck setting.Height according to combustion chamber 3 is arranged.The whirlwind runner that multilayer is formed can more strengthen and stablize, and also more strengthens the raising of efficiency of combustion.
Wherein, the bottom of described deslagging chamber 2 is provided with valve 11.Open valve 11 just burning slag to be removed.
Wherein, described heat energy detector 12 is distributed in the bottom of described combustion chamber 3.Due to heat be rise, combustion centre can be confirmed more exactly so be arranged at bottom combustion chamber 3, and heat energy detector 12 can be avoided damage by high temperature.
Above embodiment is just to illustrate instead of restriction the utility model, therefore all equivalences done according to the method described in the utility model patent claim change or modify, and are included in the utility model patent claim.
