Abstract
The utility model provides a boiler of burning furfural residual, belonging to the water-tube boiler. The utility model is characterized in that tail gas of the boiler is utilized to carry out baking for the furfural residual, and then the flue gas and the furfural residual are sent to a cyclone separator to carry out separation; after the furfural residual is baked, the furfural residual falls into a burning chamber through an agitator in timing and in fixed quantity; the furfural residual burns when falling; the furfural residual which is not burnt out falls on a fire grate and continues to burn; a slag-blocking wall is arranged in the burning chamber in order to prevent the furfural residual from falling into a counter-flow pipe bundle of the boiler; a first-wind, a rotary-wind and a second-wind feeding devices are arranged in the utility model in order to make the burning of the furfural residual even more thorough. The utility model has the advantages of energy saving, low power consumption, low cost, improvement of work environment and air pollution reduction.
Description
The utility model is a kind of steel stove of the furfural dregs that burns, and belongs to water-tube boiler.
At present, existing hand bakes the steel stove of deciding fire grate burning furfural dregs and generally adopts single drum.The hand-fired boiler of fixed grate.This boiler adopts the mode of coal and furfural dregs mixed combustion.It is a lot of that this boiler improves the furfural production cost, and fireman's labour intensity is big.Because boiler is an operation under positive pressure, fireman's operating environment is quite abominable.General furfural dregs water content reaches about 40%, makes boiler be difficult for normal combustion.The dust-exhausting quantity of boiler and dust exhausting concentration are considerably beyond national Specification.Cause very big harm for ecological environment and people's lives.The thermal efficiency of boiler is lower, generally below 40%.
The purpose of this utility model provides a kind of boiler tail flue gas waste heat that utilizes, and the furfural dregs that generally contains 40% left and right sides moisture content is dried and preheating, makes the furfural dregs can clean-burning boiler.
The utility model is realized with following technical scheme: oven dry flue 1 bottom is communicated with boiler exhaust gas discharging flue 13, and oven dry flue 1 top is communicated with cyclone separator 2.Cyclone separator 2 is equipped with poking device 3, and the outlet of poking device 3 communicates with combustion chamber 4.Top in combustion chamber 4 is provided with slag blocking wall 11.In the burner hearth back burning chamber 12 is set.Fire grate 5 is equipped with in 4 bottoms, combustion chamber, and fire grate 5 belows are equipped with wind blower fan 6 one time, and rotation wind airduct 7 is housed on the furnace wall of combustion chamber 4, is connected with secondary wind air channel 8 in the exit of poking device 3, at the boiler furnace rear steel nest of boiler tube 9 is housed.Flue 10 links to each other with air-introduced machine, and waste gas and flue gas are discharged by chimney.
The utility model compared with prior art has energy-saving and cost-reducing, reduces the furfural production cost, reduces labour intensity, improves working environment, reduces atmosphere pollution, improves the thermal efficiency, and aerogenesis is fast, safe and reliable remarkable advantage.
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is a specific embodiment of the utility model.Oven dry flue 1 top is communicated with cyclone separator 2.Cyclone separator 2 is equipped with poking device 3, and the outlet of poking device 3 communicates with combustion chamber 4.Top in combustion chamber 4 is provided with slag blocking wall 11.In the burner hearth back burning chamber 12 is set.Fire grate 5 is equipped with in 4 bottoms, combustion chamber, and fire grate 5 belows are equipped with wind blower fan 6 one time, and rotation wind airduct 7 is housed on the furnace wall of combustion chamber 4, is connected with secondary wind air channel 8 in the exit of poking device 3, and the steel nest of boiler tube 9 is housed in the boiler furnace cavity.Tail gas flue 10 links to each other with air-introduced machine.
The utility model course of work is general furfural dregs to be inserted the oven dry flue 1 of boiler tail, utilizes hot blast power to be transported to while drying to carry out in the cyclone separator 2 separating of cigarette and furfural dregs.Furfural dregs after the oven dry falls in the combustion chamber 4 at regular time and quantity by poking device 3.Furfural dregs burns while falling, and unburnt furfural dregs drops on the fire grate 5 and burns away.More abundant for the burning that makes furfural dregs, be provided with air-supply arrangements such as wind, rotation wind, secondary wind.One time wind is mainly supplied with the required air capacity of furfural dregs; the configuration of rotation wind mainly makes furfural dregs form an air-flow of rotation at a high speed in the combustion chamber; air is mixed fully with furfural dregs; secondary wind dispose two purposes: the one, making furfural dregs fall into burner hearth can burn rapidly, the 2nd, the protection poking device is unlikely by high temperature gas flow and burns out.The slag blocking wall that is provided with in the combustion chamber prevents that effectively flue gas from bringing furfural dregs in the boiler convection bank into.Be provided with burning chamber in the burner hearth back, make flue gas a depositing dust process be arranged, thereby guarantee that the boiler smoke discharging reaches state-set standard at this.
