Background technology
Biomass boiler refers to the boiler as fuel with biomass energy.There is environmental protection compared with coal-burning boiler, totally
Etc. advantage, biomass boiler system generally includes 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, produced after the completion of burning
High-temperature flue gas is purified by the heat convection in smoke pipe into deduster, is most discharged afterwards through air-introduced machine by chimney.
Dust pelletizing system of the prior art generally includes cyclone dust collector and sack cleaner.In the reality of biomass boiler
Border is in use, during due to biomass combustion, flue gas easily takes the fuel particle also in burning out of, and these particles enter cloth bag
Deduster, which is possible to cause cloth bag to catch fire, to cause the accident, therefore flue gas will first pass through cyclone dust removal before sack cleaner is entered
Device or Multi-tube cyclone duster carry out the particle of big of dedusting sedimentation filtration.But because cyclone dust collector is difficult to be burning
Fuel particle all catch, the fuel particle being burning leaked through, which enters sack cleaner, may light cloth bag and cause combustion
Burn.For this reason, sack cleaner 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 of many number of times is changed, causes to waste.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
When the prior art for being considered as recognizing or implying the information structure in any form well known to persons skilled in the art.

It is secondary to catch the particle for entering pipeline and protect cloth bag with cooling function.The main purpose for forming U-shaped flue is separator tube
The effect for extinguishing part may be reached in road with the particle of Mars.
(2) install a flame-retardant device additional in the intake stack lower end in U-tube road, resistance is conveyed during biomass boiler burns stove
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 has now been put out
Go out, play a part of pre- fire extinguishing.Fire retardant is entered by pipeline to be adsorbed onto on cloth bag in sack cleaner, is formed in cloth bag surface
Flame-retardant layer, realizes that Mars can not cause cloth bag to burn, and makes Mars absorption in cloth bag surface, due to that can not cause burning, 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 simple to operate and resistance
Fire the features such as agent is reusable.
