Abstract
The utility model provides a fluidized bed furnace waste heat utilization system, include: install first flashboard or draught fan on fluidized bed furnace tail heat extraction tobacco pipe is said, hot cigarette that will arrange the outward backflow pipeline before the fluidized bed furnace air -blower that flows back, backflow pipeline with flashboard or draught fan link to each other, and install the second flashboard on backflow pipeline, controlling means, the input links to each other with the oxygen assay appearance of installing on the air -blower bellows, the output with the second flashboard links to each other, receives oxygen content in the air -blower bellows of oxygen assay appearance survey is controlled according to the oxygen content the second flashboard, the control phegmal reflux. Before flowing back the fluidized bed furnace air -blower with fluidized bed furnace tail heat extraction cigarette via backflow pipeline to after flowing back hot -blast and cold air mixing, improve the blast temperature and can reach the required oxygen and the amount of wind of fluidized bed furnace burning, reduced the heat loss, practiced thrift the coal consumption.
Description
Technical field
The utility model belongs to plasterboard factory accessory system, particularly relates to a kind of fluidized bed furnace bootstrap system.
Background technology
Fluidized bed furnace is the important technological equipment of gypsum board production line heat supply, fluidized bed furnace in gypsum board production line is in running, and about tail smoke discharging temperature reaches 110-150 degree, these flue gases only have fraction backflow to utilize, major part is directly discharged after desulfurization, causes thermal waste.
So the hot temperature smoke backflow how to be arranged by fluidized bed furnace utilizes, reach the object of consumption reduction of economizing on coal outward, become the problem that technical staff needs to consider.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of fluidized bed furnace bootstrap system, and the hot temperature smoke backflow arranged outward by fluidized bed furnace utilizes, and reaches the object of consumption reduction of economizing on coal.
In order to solve the problems of the technologies described above, the utility model provides a kind of fluidized bed furnace bootstrap system, comprising:
Be arranged on the first flashboard on fluidized bed furnace tail heat extraction smoke pipeline or air-introduced machine;
The hot cigarette of outer row is back to the reflux line before fluidized bed furnace air blast, and described reflux line is connected with described flashboard or air-introduced machine;
And the second flashboard be arranged on reflux line;
Control device, input is connected with the determination of oxygen content instrument be arranged on air blast bellows, and output is connected with described second flashboard, receive described determination of oxygen content instrument measure air blast bellows in oxygen content, the second flashboard according to Control for Oxygen Content, controls capacity of returns.
Preferably, described control device is programmable logic controller (PLC).
The fluidized bed furnace bootstrap system that the utility model provides, before fluidized bed furnace tail heat extraction cigarette is back to fluidized bed furnace air blast via reflux line, thus after reflux hot blast and cold air mixing, improve blast temperature and the oxygen that can reach needed for boiling furnace combustion and air quantity, reduce heat loss, save coal consumption.Hot temperature smoke backflow fluidized bed furnace can arranged outward utilizes, thus realizes Waste Heat Reuse, economize energy.
