Abstract
The utility model relates to a blast furnace preheater field, in particular to preheater air feed device, a serial communication port, including communicating pipe, communicating pipe one end links to each other with preheater air manifold, and the communicating pipe other end links to each other with hot-blast furnace air manifold, is equipped with the governing valve on communicating pipe. The regulating valve is a butterfly electric valve. Compared with the prior art, the beneficial effects of the utility model are that: the surplus air quantity of the combustion-supporting fan of the hot blast stove is skillfully utilized, so that the normal operation of the preheating furnace can be met, a large amount of power consumption and maintenance cost of the combustion-supporting fan of the preheating furnace can be saved, and great benefits are brought to the energy conservation and emission reduction of iron works.
Description
Technical field
The utility model relates to blast furnace preheating oven field, particularly a kind of preheating oven air supply device.
Background technology
The hotblast stove of blast furnace and the air feed system of preheating oven are respectively by separate hotblast stove burner blower and preheating oven burner blower air feed at present; Air quantity and blast wherein in order to guarantee hotblast stove; Hotblast stove burner blower parameter is generally all got the lower limit of nominal air delivery, makes fan capacity that certain having more than needed arranged; And the burner blower of preheating oven is just kept normal burning stove, so preheating oven burner blower type selecting is less, two burner blowers are worked simultaneously in the production, and consumes power is very big, and maintenance cost is also very high.
Summary of the invention
The purpose of the utility model provides a kind of preheating oven air supply device, utilizes the air quantity more than needed of hotblast stove burner blower, satisfies the normal operation of preheating oven, practices thrift the power consumption and the maintenance cost of the burner blower of preheating oven.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of preheating oven air supply device comprises pipe, said pipe one end link to each other with the preheating oven air main, pipe the other end link to each other with the hotblast stove air main, pipe is provided with variable valve.
Said variable valve is the butterfly electrically operated valve.
Compared with prior art; The beneficial effect of the utility model is: the air quantity more than needed that utilizes the hotblast stove burner blower dexterously; Can satisfy the normal operation of preheating oven; Can practice thrift a large amount of power consumptions and the maintenance cost of the burner blower of preheating oven again, for the energy-saving and emission-reduction of iron work bring very large benefit.

Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
See Fig. 1; It is a kind of preheating oven air supply device of the utility model example structure synoptic diagram; Comprise preheating oven burner blower 1, hotblast stove burner blower 2, preheating oven air main 3, hotblast stove air main 4, blower fan outlet valve 1, blower fan outlet valve 26 and pipe 7; Pipe 7 one, end linked to each other with preheating oven air main 3, pipe 7 the other end link to each other with hotblast stove air main 4, pipe 7 is provided with variable valve 8.Variable valve 8 is the butterfly electrically operated valve.
Wherein the fan parameter of hotblast stove burner blower 2 is: electric moter voltage is 10,000 volts, and frequency is 50 hertz, blast volume 225396Nm
3, blast 15000Pa, rotating speed 1480r/min, power of motor 1400kW, required combustion-supporting air quantity peak is 160000m during the hotblast stove trouble-free burning
3/ h, so hotblast stove burner blower 2 65396 m more than needed
3The air quantity of/h.
And required combustion-supporting air quantity peak is 30000 m during the preheating oven trouble-free burning
3/ h, the fan parameter of preheating oven burner blower 1 is: blast volume 43452Nm
3, blast 11000Pa, rotating speed 1480r/min; Power of motor 220kW, electric moter voltage is 10,000 volts, sees from fan parameter; Hotblast stove burner blower 2 is under the situation that satisfies the Combustion of Hot Air Furnace required air quantity; The required air capacity of normal burning stove of preheating oven can be guaranteed fully, after the transformation, the power consumption and the maintenance cost of preheating oven burner blower 1 can be saved.
After pipe 7 connection, when preheating oven point stove burns, variable valve 8 is opened, make hotblast stove burner blower 2 air quantity get into preheating oven air main 3, supply preheating oven burning use.Adjustment blower fan outlet valve 26 makes the air quantity output of hotblast stove burner blower 2 satisfy the hotblast stove demand, adjusts air-fuel ratio, makes the hotblast stove reasonable burning, adjusts variable valve 8 again and makes the preheating oven reasonable burning.Blower fan outlet valve 1 cuts out, and preheating oven burner blower 1 is in stand-by state.
Claims (2)
1. a preheating oven air supply device is characterized in that, comprises pipe, said pipe one end link to each other with the preheating oven air main, pipe the other end link to each other with the hotblast stove air main, pipe is provided with variable valve.
2. a kind of preheating oven air supply device according to claim 1 is characterized in that said variable valve is the butterfly electrically operated valve.
