Description
Technical field
This utility model relates to metallurgical ironmaking technology field, and specifically a kind of blast furnace pulls out wind system.
Background technology
Blast furnace blower is to be collected by a part of air, and has certain by pressurization raising air pressure formation
Pressure and the blast furnace air of flow, further according to conditions of blast furnace need carry out blast, air quantity regulation after be transported to blast furnace
A kind of dynamic power machine.Blast furnace air supply system has the air blast of certain pressure and high flow velocities by high pressure blower output, through cold
The conveying of the blowing devices such as wind pipeline, air stove and hot air duct, air blast is sent into certain pressure and higher flow velocity the most at last
Blast furnace.At weather in rainy season, time particularly with thunder and lightning, easily be there is tripping operation power-off by effects of lightning in traditional Blast Furnace Blower System
Accident, causes blast furnace blowing-out, and air port, elbow even bustle pipe fills slag, needs to arrange for special personnel and goes maintenance, processes, increases
Add labor intensity, reduced production efficiency, too increase production cost simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of blast furnace to pull out wind system, with asking of solving to propose in above-mentioned background technology
Topic.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of blast furnace pulls out wind system, including the first blower fan, the second blower fan, the first blast furnace and the second blast furnace；Described first wind
Machine is connected with pipeline, and pipeline is provided with non-return valve, and non-return valve lower channel branches into A pipeline and right side pipeline, right side pipeline
It is connected with the first blast furnace；Described second blower fan is connected with pipeline, and pipeline is provided with non-return valve, and non-return valve upper end pipeline branches into
B pipeline and right pipeline, right pipeline and the second blast furnace connect；It is provided with on described A pipeline and B pipeline and pulls out air-valve B, A pipeline and B
Pipeline is connected by C pipeline, C pipeline is provided with and pulls out air-valve A.
As further program of the utility model: described non-return valve uses stainless steel.
Compared with prior art, the beneficial effects of the utility model are:
This blast furnace air dispensation system is reasonable in design, it is possible to be prevented effectively from the slag tuyere because causing without plan blower fan tripping operation damping down
Major accident, thus reduce a large amount of manpower loss and equipment loss；And the air blast in blast furnace is only produced checking and in short-term
Between stop wind action, on produce impact less；It addition, this Blast Furnace Blower System also has, safety is high, production efficiency is high
Advantage.
Accompanying drawing explanation

Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Referring to Fig. 1, a kind of blast furnace pulls out wind system, high including first blower fan the 1, second blower fan the 2, first blast furnace 3 and second
Stove 4；Described first blower fan 1 is connected with pipeline, and pipeline is provided with non-return valve 7, and non-return valve 7 lower channel branches into A pipeline 8 He
Right side pipeline, right side pipeline and the first blast furnace 3 connect；Described second blower fan 2 is connected with pipeline, and pipeline is provided with non-return valve 7,
Non-return valve 7 upper end pipeline branches into B pipeline 9 and right pipeline, right pipeline and the second blast furnace 4 and connects；Described A pipeline 8 and B pipeline 9
On be provided with and pull out air-valve B6, pulling out air-valve B6 is normally open, and A pipeline 8 and B pipeline 9 is connected, on C pipeline 10 by C pipeline 10
Being provided with and pull out air-valve A5, pulling out air-valve A5 is closed mode when blast furnace normally works, when single seat blast furnace generation blower fan trips, abnormal
During accident air draft, opening wind turning valve A5, a certain amount of air blast is sent in abnormal blast furnace by normal blast furnace.As preferably, described inverse
Only valve 7 uses stainless steel.
Operation principle of the present utility model is: connected by two blast furnace air supply systems, increases wind turning dress at serial pipe
Putting, when single seat blast furnace generation blower fan trips, during abnormal accident air draft, open wind turning valve A5, a certain amount of air blast is sent by normal blast furnace
Enter in abnormal blast furnace, it is possible to avoid the generation of the serious accident of supply air system blowpipe, elbow or even bustle pipe filling slag.
This blast furnace air dispensation system is reasonable in design, it is possible to be prevented effectively from the slag tuyere because causing without plan blower fan tripping operation damping down
Major accident, thus reduce a large amount of manpower loss and equipment loss；And the air blast in blast furnace is only produced checking and in short-term
Between stop wind action, on produce impact less；It addition, this Blast Furnace Blower System also has, safety is high, production efficiency is high
Advantage.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
