Abstract
The utility model relates to a hot air strip steel drying device for a continuous type heat treatment unit, comprising an air injecting cooling section (1), a water spraying cooling section (2), a drying section (3), a ventilating duct (10) and a pressurizing fan (6), wherein one end of the ventilating duct (10) communicates with end part of the air injecting cooling section (1), while the other end connects with middle part of the drying section (3); the pressurizing fan (6) is arranged on the ventilating duct (10). With the hot air strip steel drying device of the utility model, hot air produced by the continuous type heat treatment unit can be reused, which, in the premise of technological demand satisfaction, optimizes the equipment, saves the investment and lowers the operation cost.
Description
Technical field
The utility model relates to a kind of continous way heat treatment unit, particularly a kind of continous way heat treatment unit band steel hot-air drying device.
Background technology
The hot blast of band steel hot-air drying device is from two steam/air heat exchangers in the conventional design.The high-temperature steam of coming from being situated between blasts heat transferred by heat exchanger from blower fan air, heated air form heated-air drying band steel.
Usually, the required hot air technique parameter of dry zone steel is: flow 7000Nm3/h, 110 ℃ of temperature, pressure 12000pa.Therefore the band steel hot-air drying device of conventional design under the situation of the steam pressure of coming of being situated between, temperature stabilization accordingly steam consumption quantity be 480kg/h.
List sees that with regard to the aspect that satisfies process conditions this scheme is no problem.But consider before the water spray cooling section air blown cooling section is arranged in conjunction with unit is whole, a large amount of air obtains more heat and discharges with the hot blast form behind the salband steel.The available hot blast parameter of air blown cooling section is 200 ℃ of temperature, flow 60000Nm/h, pressure 2000Pa, and its temperature, flow all can meet the demands.
The band steel hot-air drying device of conventional design does not utilize the hot blast of this section of unit self generation, will will set up the steam/air heat exchanger system when building, and has increased investment, and also will consume a large amount of steam when operation.
Summary of the invention
For addressing the above problem, the utility model provides a kind of band steel hot-air drying device, realizes that continous way heat treatment unit self produces the utilization again of hot blast.
For achieving the above object, band steel hot-air drying device of the present utility model, comprise air blown cooling section 1, water spray cooling section 2, dryer section 3, ventilation shaft 10 and booster fan 6, one end of described ventilation shaft 10 is communicated with the afterbody of air blown cooling section 1, the other end is communicated with the middle part of dryer section 3, and described booster fan 6 is arranged on the ventilation shaft 10.
Have cold wind suction inlet 8 on the described ventilation shaft 10, and on the cold wind intake line, control valve 9 is installed, before described cold wind suction inlet 8 is positioned at booster fan 6.
The two ends of described ventilation shaft 10 are respectively arranged with control valve 5,12 and thermocouple 4,11.
On the ventilation shaft 10 before described booster fan 6 filter 7 is installed.
By band steel hot-air drying device of the present utility model, realized the utilization again that continous way heat treatment unit self produces hot blast, satisfying under the prerequisite of technological requirement, optimize equipment, saved investment, reduced operating cost.
Description of drawings
Fig. 1 is band steel hot-air drying device schematic diagram.
The specific embodiment
Continous way heat treatment unit will be with the slow cooling of steel (cooling velocity＜10 ℃/s), cold (cooling velocity＞30 ℃/s) and drying process soon after band steel heat treatment is finished.High temperate zone steel more than 800 ℃ is from first entering the air blown cooling section, and air sprays at a high speed, and belt steel surface is blowed air and is cooled to below 600 ℃, produces a large amount of hot blast that uniform temperature is arranged.The cooling section of spraying water is subsequently undertaken cold soon by water spray, will be with steel to be cooled to enter dryer section subsequently below 80 ℃.
To be with steel from being cooled to more than 800 ℃ below 600 ℃ after air blown cooling section cold air spirt goes, air is produced the hot blast that is about 200 ℃ of temperature, flow 60000Nm3/h, pressure 2000Pa at this with the steel heating.And the dry hot blast parameter that needs of band steel is flow 7000Nm3/h, 110 ℃ of temperature, pressure 12000pa.
Fig. 1 is band steel hot-air drying device schematic diagram.As shown in the figure, band steel hot-air drying device, comprise air blown cooling section 1, water spray cooling section 2, dryer section 3, ventilation shaft 10 and booster fan 6, one end of described ventilation shaft 10 is communicated with the afterbody of air blown cooling section 1, the other end is communicated with the middle part of dryer section 3, and described booster fan 6 is arranged on the ventilation shaft 10.
At ventilation shaft 10 booster fan 6 is set, makes that spraying into hot-blast pressure in dryer section satisfies technological requirement.
The discharging hot blast temperature of air blown cooling section 1 is higher than dry required temperature, for guaranteeing the drying process temperature, can on ventilation shaft 10, open a cold wind suction inlet 8, a control valve 9 control soakages are installed simultaneously, before described cold wind suction inlet 8 is positioned at booster fan 6 on the cold wind intake line.
Because the variation of air blown cooling section 1 discharging hot blast temperature and the variation that cold wind suction inlet 8 is mixed cold blast rate, institute is for the hot air flow instability of dryer section 3, for guaranteeing that being stabilized in booster fan 6 outlets installs a flow control valve 5 adjustment flows.
End at the ventilation shaft 10 that is communicated with dryer section 3 is installed a thermocouple 4, mixes the signal of control valve 9 controls of cold wind with supply cold wind suction inlet 8.
A control valve 12 is installed on one end of the ventilation shaft 10 that is communicated with air blown cooling section 1 is discharged the hot blast soakage, and a thermocouple 11 is installed, be used to measure the hot blast temperature of air blown cooling section 1 to adjust.
Consider that the temperature of drawing hot blast must be higher than certain value, so collect hot blast at air blown section 1 afterbody.Hot blast is jetted and is discharged by two ends to dryer section 3 backs, is selected in dryer section 3 middle parts so hot blast sprays into the position.
Carry brown iron oxide secretly for the discharging hot blast that prevents air blown cooling section 1 and enter draught fan impeller, influence the dynamic balancing of blower fan, it is overanxious that filter 7 of installation carries out air on the pipeline before booster fan 6.
For reducing noise, muffler can be installed at blower fan import and export place.
