The utility model discloses a high-speed wire air cooling waste heat recovery device. The high-speed wire air cooling waste heat recovery device is characterized by comprising a waste heater boiler and an air collecting cover arranged above a high-speed wire conveying roller way. The air collecting cover is connected with the inlet of the waste heat boiler through a pipe, and the outlet of the waste heat boiler is connected with a fan at the bottom of the high-speed wire conveying roller way. Cold air heated by high-speed wires is collected by the air collecting cover, then enters the waste heat boiler for circulation and heat exchange and lastly returns to the inlet of the fan for circulating cooling. The high-speed wire air cooling waste heat recovery device can collect sensible heat of the high-speed wires within a temperature range between 850 DEG C and 300 DEG C, generate steam which can be supplied to downstream users and provide an effective approach to further achieving energy saving and emission reduction of iron and steel enterprises.
Description
Technical field
The utility model relates to a kind of waste-heat recovery device, relates in particular to the air-cooled waste-heat recovery device of a kind of high-speed rod.
Background technology
Be the important period that big to strong was accelerated restructuring, striven for to China's steel industry " 12 " period.More manifest in the face of Steel Industrial meagre profit feature, the problem such as homogeneity competition increasingly sharpens, and energy-saving and emission-reduction task is more arduous, cost efficiency, energy recovery have become the effective way of iron and steel enterprise's Improve Efficiency.In vast high line production line, it not only loses the energy Stanermo wind-cooling linear, and shopwork environment is caused to adverse effect.While producing common building with high line, Laying head outlet temperature is approximately 850 ℃, approximately 300 ℃ of collection volume temperature, every two about 200t/h of high line output, every air-cooled line metal flow flux is 100t/h, every air-cooled line zone leveling heat dissipation capacity is 44GJ/h, from the angle of UTILIZATION OF VESIDUAL HEAT IN, on-the-spot heat energy dissipation cannot be recycled rather unfortunate.
Utility model content
The purpose of this utility model is to provide a kind of high-speed rod air-cooled waste-heat recovery device, has the function of flue gas waste heat recovery, is conducive to steel plant's energy-saving and emission-reduction.
The purpose of this utility model is to realize like this, the air-cooled waste-heat recovery device of a kind of high-speed rod, it is characterized in that: described device comprises waste heat boiler and is arranged on the wind-collecting cover of the top of carrying high line roller-way, wind-collecting cover is connected with waste heat boiler import by pipeline, and heat boiler outlet is connected with carrying the blower fan of high trajectory bottom by pipeline.
The high-temperature flue gas that enters flue from wind-collecting cover top enters waste heat boiler cooling, from boiler tail, discharge, through back-end ductwork, enter and carry the cooling blower of high line roller-way bottom to reheat to circulate;
For the flow in flue detects and controls, described wind-collecting cover upper flue is all equipped with flowmeter and bypass regulator valve;
In order to improve smoke collecting efficiency, described wind-collecting cover is divided into high-temperature region and low-temperature space by the high line roller-way of conveying;
In order to reduce risk, on high temperature wind-collecting cover and low temperature wind-collecting cover, chimney is housed;
On described chimney, stop valve is housed, but has and open soon function;
Described waste heat boiler is double voltage type waste heat boiler;
The utility model can reclaim the sensible heat of high line from 850 ℃ to 300 ℃, and the steam of generation can supply downstream user, for further realizing iron and steel enterprise's energy-saving and emission-reduction, provides an effective way.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
Part 1 is waste heat boiler; Part 2 is for carrying high line roller-way; Part 3 is magnetic valve; Part 4 is that stop valve, part 5 are bypass regulator valve; Part 6 is flowmeter; Part 7 is chimney; Part 8 is high temperature wind-collecting cover; Part 9 is low temperature wind-collecting cover; Part 10 is cooling blower; Part 11 is high speed cooling blower.
The specific embodiment
As shown in Figure 1, the air-cooled waste-heat recovery device of high-speed rod, comprises waste heat boiler 1, carries high line roller-way 2, high temperature wind-collecting cover 8, low temperature wind-collecting cover 9, cooling blower 10, connects flue, by-pass flue, connection flue flowmeter 6, bypass regulator valve 5 and chimney 7.Above the high line roller-way of conveying, wind-collecting cover 8 is housed, wind-collecting cover 8 is connected with waste heat boiler 1 import by connecting flue, and heat boiler outlet is connected with carrying the blower fan of high trajectory bottom.
During work, Laying head outlet high temperature wire rod 2 temperature are 850 ℃ of left and right, enter after high temperature wire rod roller-way, and the cooling blower 10 of roller-way bottom is cooling to its air blast, and along the wire temperature of roller-way feed direction from high to low, roller-way outlet wire temperature is reduced to 300 ℃.By respectively the hot blast of high-temperature region and low-temperature space being collected with wind-collecting cover, the high Low Temperature Thermal wind of collection is sent into respectively in waste heat boiler 1 by pipeline, then from waste heat boiler afterbody, out gets back to the entrance of cooling blower.When starting wind-warm syndrome when very low, can wind-warm syndrome be improved by hydronic method, open boiler water cycle cooling system after reaching rational boiler inlet temperature, reach the stable operation of system.Wind-collecting cover is provided with chimney 7, and chimney 7 is provided with the stop valve 4 of opening soon, and when system pressure is too high, the stop valve of opening on chimney is emitted partial fume.High-temperature region chimney and boiler back end ductwork are provided with by-pass flue, when pressure increases, by the bypass regulator valve 5 on by-pass flue, part low-temperature flue gas are diffused.The rearmost end of roller-way is provided with a high speed cooling blower 11, when outlet wire rod excess Temperature, opens, and guarantees the final chilling temperature of wire rod.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
