Detailed description of the invention
As shown in Figure 1, the utility model changes Installed to traditional bagasse boiler, is to reequip on the basis of the original configuration of boiler, add follow ring combustion burn Installed put and dry dust removal apparatus of discharging fume at least each a set of, overheavy firing and smoke abatement and dust control, accomplish safety, efficient, environment-protecting clean operation.
The utility model by burner hearth 1, superheater 2, drum 3, convection bank 4, economizer 5, air preheater 6, water dust scrubber 8, the compositions such as chimney 9 and bagasse boiler circulating combustion and smoke evacuation dry dust removal apparatus.
Bagasse boiler circulating combustion and smoke evacuation dry dust removal apparatus, comprise combustible soot separator, cigarette ash Flue Gas Forced Draft Fan and corresponding pipeline valve, the circulating combustion device of secondary air channel and spout composition, the air intake feed pipe of cigarette ash Flue Gas Forced Draft Fan 14 is connected with combustible soot separator 15 bottom drain, the efferent duct UNICOM of secondary air channel 16 and cigarette ash Flue Gas Forced Draft Fan 14, the air intake feed pipe of cigarette ash Flue Gas Forced Draft Fan 14 there are flue gas arm 12 and air arm 13, discharge flue gas was equipped with smoke evacuation dry dust removal apparatus 7 before water dust scrubber 8, the motor of air-introduced machine 11 is equipped with speed regulator 10.
The motor of cigarette ash Flue Gas Forced Draft Fan 14, is equipped with speed regulator or adjustable varying-speed motor.
Coke button scavenge unit is arranged at combustible soot separator 15 bottom drain bottom.
Flue gas arm 12 and air arm 13 are provided with adjustable gate.
Air arm 13 communicates with boiler primary air piping or the outer air of stove.
1 bar flue gas arm 12 and boiler air preheater 6 top or other position exhaust gases passes UNICOM at the most.
Bagasse boiler circulating combustion and smoke evacuation dry dust removal apparatus are at least respectively installed a set of.
When bagasse boiler runs, the bagasse that boiler tube 18 enters burner hearth 1 bottom is entered from fuel bagasse, under the high temperature secondary wind and combustible soot injection immixture of its lower secondary air channel 16 spout ejection, send forth at the rapid ignition of burner hearth 1 lower space, the fuel bagasse be scattered on a small quantity on fire grate 17 burns away under the effect of furnace bottom First air.The flue gas after the cigarette ash of burner hearth 1, superheater 2 that flies out isolates combustible soot through combustible soot separator 15, delivery pipe bottom combustible soot separator 15, cigarette ash Flue Gas Forced Draft Fan 14 is together entered with appropriate high-temperature flue gas, by regulating the rotating speed of cigarette ash Flue Gas Forced Draft Fan 14, the valve opening of flue gas arm 12 and air arm 13 is regulated to reach optimum cycle combustion conditions.Isolate the high-temperature flue gas after combustible soot and wash away convection bank 4, economizer 5 and air preheater 6, owing to not having smoke deposition Re Jiao Change efficiency to improve, and stopped on air preheater because of deposition a large amount of cigarette ashes burn suddenly, burn out the generation of the serious boiler breakdowns of air preheater.Thus make boiler safety, Effec-tive Function.
From air preheater 6 flue gas out and the trickle cigarette ash carried with flue gas, through smoke evacuation dry dust removal apparatus 7, most cigarette ash separated and collected is discharged, flue gas after dry dust removal enters water dust scrubber 8, flue gas up to standard again after udst separation, is transported to chimney 9 by air-introduced machine 11 suction and enters sky.Air-introduced machine 11, under speed regulator 10 regulable control, makes boiler operatiopn operating mode remain on optimal operational condition.
The utility model also has a kind of embodiment of single drum-type boiler, as shown in Figure 2, its structure is substantially identical with the structure of Fig. 1 embodiment, by the exhaust gases passes of combustible soot separator 15 and the rear corresponding exhaust gases passes UNICOM of boiler superheater 2 when being the different ， An Installed of layout of superheater 2.
