The steel wire fired heater is a kind of equipment that steel wire is heat-treated, and is provided with preheating section, heating zone and soaking zone in burner hearth, and temperature of each section and air-fuel ratio are all inequality, and the traffic direction of steel wire is opposite with the traffic direction of flue gas.In order to recycle the waste heat of the flue gas that fired heater discharges, in smoke-uptake, be provided with preheater.This preheater utilizes the waste heat of flue gas to come preheating to lead to the combustion air of each section in the fired heater burner hearth.
Traditional preheater is provided with a cold-air duct and a hot-blast main, and the hot-blast main is divided into several roads hot blast manifold again and leads to each interior section of fired heater burner hearth.For the air-fuel ratio side reaction coefficient of regulating each section (being air and the ratio of fuel), each hot blast manifold is provided with a whole set of computer automatic controlled system of automatic control side reaction coefficient, and the topworks of this system is electronic hot blast valve.This hot blast valve is owing to expanded by heating, and hot blast valve is stuck easily, malfunctioning, solves stuck problem by the gap of amplifying hot blast valve in the actual production.The hot blast valve low precision in big gap leaks out easily, and particularly when fired heater was in abortion amount production status, the air capacity of soaking zone exceeded standard, and caused the oxide skin of steel wire serious, influenced the quality of steel wire.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of Steel Wire Heat Treatment fired heater that has apportion combined type preheating device is provided, this fired heater can accurately be adjusted the air capacity towards each section, and the wire quality of production is good.
According to technical scheme of the present invention: a kind of Steel Wire Heat Treatment fired heater that has apportion combined type preheating device, in smoke-uptake, be provided with preheater, described preheater comprises by connecting hot bellows and the packaged air conditioner that vent-pipe is communicated with, described hot bellows and described packaged air conditioner are separated into a plurality of chambers by dividing plate respectively, each chamber of described hot bellows is communicated with by the described vent-pipe that is connected respectively with each chamber of corresponding described packaged air conditioner, be respectively arranged with a heating duct on each chamber of described hot bellows, each root heating duct leads to each section of described fired heater respectively, be respectively arranged with a cold-air duct on each chamber of described packaged air conditioner, each root cold-air duct all is communicated to the cold wind house steward, and every described cold-air duct is provided with cold blast valve.
Described cold blast valve links to each other with the robot control system(RCS) of described fired heater.
Described cold wind house steward is connected with blower fan.
Described cold blast valve adopts electric butterfly valve.
Described cold blast valve adopts electronic ratio adjusting valve.
Technique effect of the present invention is: the present invention changes system into hyperchannel apportion combined type preheating device with preheater, the air capacity that enters each cold-air duct of preheater by adjustment is controlled towards the air capacity of each working zone of fired heater, cold blast valve work at normal temperatures, easily realize control automatically, and automatic control precision height; Heat energy utilization rate height of the present invention, the Heat stability is good of stove, the wire quality of production is good.
Description of drawings

Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A-A sectional view among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Among Fig. 1 ~ Fig. 3, comprise fired heater 1, smoke-uptake 2, preheater 3, heating duct 4, dividing plate 5, cold-air duct 6, cold blast valve 7, cold wind house steward 8, hot bellows 9, packaged air conditioner 10, connect vent-pipe 11, chimney 12, exhanst gas outlet 13, smoke inlet 14 etc.
As Fig. 1 ~ shown in Figure 3, the present invention is a kind of Steel Wire Heat Treatment fired heater that has apportion combined type preheating device.In the smoke-uptake 2 of fired heater 1, be provided with preheater 3.
This preheater 3 is the march-past preheater, comprises by connecting hot bellows 9 and the packaged air conditioner 10 that vent-pipe 11 is communicated with.Hot bellows 9 and packaged air conditioner 10 are separated into a plurality of chambers by dividing plate 5 respectively.Each chamber of hot bellows 9 is communicated with by being connected vent-pipe 11 respectively with each chamber of corresponding packaged air conditioner 10.Be respectively arranged with a heating duct 4 on each chamber of hot bellows 9, each root heating duct 4 leads to each section of fired heater 1 respectively.Be respectively arranged with a cold-air duct 6 on each chamber of packaged air conditioner 10, each root cold-air duct 6 all is communicated to cold wind house steward 8, and every cold-air duct 6 is provided with cold blast valve 7, and cold wind house steward 8 is connected with blower fan.
When the present invention worked, high-temperature flue gas entered preheater 3 from smoke inlet 14, added hot tie-in vent-pipe 11, connected to discharge from heating duct 4 after vent-pipe 11 interior freezing airs are heated into hot blast step by step.The heat energy of high-temperature flue gas becomes low-temperature flue gas and discharges from chimney 12 through exhanst gas outlet 13, thereby form a complete heat exchanging process after being connected absorption of air in the vent-pipe 11.
