Along with the environmental protection development of science and technology, various flue gas cool-down equipment have all obtained using widely and developing.Present cooling high-temperature flue gas mainly can be divided into dual mode: air-cooled and water-cooled.
The utility model technology belongs to the spraying air cooling way of original creation, through spraying and the air-cooled method that combines, has remedied the less and little deficiency of cooling extent of traditional wind cooling temperature lowering coefficient.The utility model occupation area of equipment is little, and operation is simple.
The utility model content
The utility model technology is to utilize the cold wind of band fog to contact the heat exchange principle that carries out with flue gas through tube wall, and a kind of scientific and reasonable, heat sink that using value is high is provided.This device has the characteristics of safety, efficient, good cooling effect.
The technical scheme of the utility model is following.
Complete equipment mainly comprises: comprise smoke inlet (1), upper box (2), upper face plate (3), heat-exchanging chamber (4), flue gas tube bank (5), lower face plate (6), lower box (7), ash bucket (8), unloading valve (9), cold water pipe (10), rotational flow atomized spray injector (11), blower fan (12), dividing plate (13), exhanst gas outlet (14); Exhanst gas outlet (14) pipeline connects the blower fan exhausting; Make and form negative pressure in the heat-exchanging chamber (4); High-temperature flue gas gets into upper box (2) by smoke inlet (1), gets into the flue gas tube bank (5) in the heat-exchanging chamber (4) through upper face plate (3), high-temperature flue gas through in the process of flue gas tube bank (5) with tube wall in addition the cold air of fog produce the temperature difference; The heat of high-temperature flue gas is with the fog cold air to take away; After carrying out heat exchange, high-temperature flue gas passes lower face plate (6) and gets in the lower box (7), and the particle under the gravity effect in the flue gas is collected in the ash bucket (8); Enter into heat-exchanging chamber (4) through lower face plate (6) once more; After the heat exchange of flue gas tube bank (5) process secondary, pass upper face plate (3), get into upper box (2) and discharge from exhanst gas outlet (10), the particle that is collected in the ash bucket (8) is discharged by unloading valve (9).
On the basis of technique scheme, through dividing plate (13) smoke inlet (1) and exhanst gas outlet (14) are separated in the upper box (2), smoke inlet (1) is vertical each other with exhanst gas outlet (14) direction.
On the basis of technique scheme, heat-exchanging chamber (4) carries out heat exchange under blower fan (12) and rotational flow atomized spray injector (11) acting in conjunction, and high-temperature flue gas is walked two-tube-pass along flue gas tube bank (5) at heat-exchanging chamber (4).
On the basis of technique scheme, the spray direction of rotational flow atomized spray injector (11) is parallel with flue gas tube bank (5), and blower fan (12) air blast direction and flue gas tube bank (5) are perpendicular.Make the fog more even distribution of rotational flow atomized spray injector (11) ejection, cold wind flows to the flue gas flow direction forward and intersects, and has utilized heat exchange area to greatest extent, has also improved the heat exchanger effectiveness of system simultaneously.
The characteristics of the utility model:
1. adopt atomizing cold water to combine and increased heat exchanger effectiveness greatly with cold air;
2. replace single-pass with two-tube-pass, when reducing device height, improved heat exchange area to greatest extent;
