Background technique
Biomass boiler refers to the boiler with biomass energy as fuel.There is environmental protection compared with coal-burning boiler, completely
Etc. advantages, biomass boiler system generally include feeding system, combustion system, soot blower system, air and gas system and robot control system(RCS).Its
Middle air and gas system includes supply air system and dust pelletizing system, air inducing dust pelletizing system: under air-introduced machine effect, is generated after the completion of burning
High-temperature flue gas enters deduster purification by the heat convection in smoke pipe, is most discharged afterwards through air-introduced machine by chimney.
Dust pelletizing system in the prior art generally includes cyclone dust collector and bag filter.In the reality of biomass boiler
In use, during due to biomass combustion, flue gas is easy to take out of the fuel particle also in burning on border, these particles enter cloth bag
Deduster is possible to that cloth bag kindling is caused to cause the accident, therefore flue gas will first pass through cyclone dust removal before entering bag filter
Device or Multi-tube cyclone duster are dusted sedimentation filtration big particle.But since cyclone dust collector is difficult to be burning
Fuel particle all capture, the fuel particle being burning leaked through, which enters bag filter and may light cloth bag, to be caused to fire
It burns.For this reason, bag filter accident on fire, which happens occasionally, causes the cloth bag of manufacturing enterprise to burn out, and needs more within 1 year
The cloth bag for changing many numbers causes to waste.

It may achieve the effect that extinguish part with the particle of Mars in road.
(2) flame-retardant device is installed additional in the intake stack lower end of U-shaped pipe, conveying resistance during biomass boiler burns furnace
Agent flue is fired, under the action of the forces of the wind, fire retardant is homogeneously mixing together with flue dust, and the tiny Mars in part is put out at this time
It goes out, plays the role of pre- fire extinguishing.Fire retardant is entered in bag filter by pipeline to be adsorbed on cloth bag, is formed in cloth bag surface
Flame-retardant layer realizes that Mars can not cause cloth bag to burn, is adsorbed on Mars in cloth bag surface, due to that can not cause to burn, and reaches
To the effect gone out is burnt and sucked certainly, prevent burning bag accident from occurring.The dust pelletizing system of biomass boiler of the present invention has easy to operate and hinders
Fire the features such as agent is reusable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the dust pelletizing system of biomass boiler according to the present invention.
Specific embodiment
