Specifically, the rotation speed sensor 300 in each blast furnace blower 100 is configured to continuously acquire an actual rotation speed value of the blast furnace blower 100, and feed back the actual rotation speed value to the programmable logic controller 600 through the secondary meter 500.
Specifically, the radial displacement sensor 400 in each blast furnace blower 100 includes: an intake side radial displacement sensor 401 and an exhaust side radial displacement sensor 402. The intake side radial displacement sensor 401 is disposed on the intake side of the blast furnace blower 100, and is configured to continuously acquire actual vibration data of the intake side of the blast furnace blower 100, and feed back the actual vibration data of the intake side to the programmable logic controller 600 through the secondary meter 500.

Referring to fig. 2, the present invention provides a shutdown control method applied to a blast furnace blower 100, by way of example, the method includes the steps of:
step S201: based on the reference clock signal, actual operation data of the blast furnace blower are obtained, and whether the actual operation data meet the first shutdown condition is judged based on preset normal operation data.
Specifically, the reference clock signal includes any one of the IRIG-B signal, the NTP signal, and the SNTP signal described above, and may be sent to each blast furnace blower 100 by the time synchronization device 700, thereby providing a corresponding reference clock signal for each blast furnace blower 100.

Specifically, the normal operation data applied to the blast furnace blowers 100 may be preset according to the operation state, maintenance condition, operation time period, etc. of each blast furnace blower 100, and thus, the normal operation data between different blast furnace blowers 100 may be identical, or may not be identical, or may even be completely different.
In a specific implementation process, the normal operation data may include: a normal shaft displacement threshold and a normal rotational speed threshold. Wherein the normal shaft displacement threshold may comprise 0.81 mm to 0.99 mm and the normal rotational speed threshold may comprise 2700 rpm to 3300 rpm.
For example, the normal shaft displacement threshold may be preset to 0.85 mm or 0.9 mm. The normal rotation speed threshold may be preset to 2800 rpm or 3000 rpm.
Aiming at judging whether the actual operation data meets the first shutdown condition, specifically, if the actual shaft displacement is larger than the normal shaft displacement threshold value and the actual rotating speed is larger than the normal rotating speed threshold value, judging that the first shutdown condition is met; otherwise, the method is judged to be unsatisfied.
In a specific implementation, if the actual shaft displacement is 1 millimeter and the actual rotation speed is 3400 rotations per minute, the first shutdown condition is met by the characterization; if the actual shaft displacement is 0.8 mm and the actual rotational speed is 3400 revolutions per minute, the characterization does not satisfy the first shutdown condition; if the actual shaft displacement is 0.85 mm and the actual rotational speed is 2900 rpm, the first shutdown condition is not met by the characterization.
Step S202: if the first shutdown condition is met, acquiring actual vibration data of the blast furnace blower based on the reference clock signal, and judging whether the actual vibration data meets the second shutdown condition or not based on preset normal vibration data.
If it is determined that the actual operation data of a certain blast furnace blower satisfies the first shutdown condition, the actual vibration data may be acquired by the radial displacement sensor 400 of the blast furnace blower based on the reference clock signal. Specifically, the actual vibration data includes intake-side actual vibration data and exhaust-side actual vibration data.
In a specific implementation process, the intake side radial displacement sensor 401 may be used to obtain the intake side actual vibration data of the blast furnace blower, and the exhaust side radial displacement sensor 402 may be used to obtain the exhaust side actual vibration data of the blast furnace blower.
The intake-side actual vibration data further includes a first radial displacement and a second radial displacement, and the exhaust-side actual vibration data further includes a third radial displacement and a fourth radial displacement.
Specifically, the normal vibration data applied to the blast furnace blowers 100 may be preset according to the operation state, maintenance condition, operation time period, etc. of each blast furnace blower 100, and thus, the normal vibration data between different blast furnace blowers 100 may be identical, or may not be identical, or may even be completely different.
In a specific implementation, the normal vibration data may include: intake side vibration displacement threshold value and exhaust side vibration displacement threshold value. Wherein the intake side vibration displacement threshold may include 131 micrometers to 161 micrometers; the exhaust side vibration displacement threshold may include 146 micrometers to 161 micrometers.
For example, the intake side vibration displacement threshold may be preset to 145 micrometers or 146 micrometers. The exhaust side vibration displacement threshold may be preset to 140 micrometers or 146 micrometers.
For judging whether the actual vibration data meets the second shutdown condition, specifically, if any one of the following conditions is met, judging that the second shutdown condition is met:
the first radial displacement is greater than the intake side vibration displacement threshold.
The second radial displacement is greater than the intake side vibration displacement threshold.
The third radial displacement is greater than the exhaust side vibration displacement threshold.
The first radial displacement is greater than the exhaust side vibration displacement threshold.
Otherwise, the second stop condition is not satisfied.
It should be noted that, the first radial displacement may be: the radial displacement value of the air intake side shaft of the blast furnace blower 100 in the plumb direction may be: radial displacement value of the intake side shaft of the blast furnace blower 100 in the horizontal direction.
Similarly, the third radial displacement may be: the radial displacement value of the exhaust side shaft of the blast furnace blower 100 in the plumb direction may be: radial displacement value of the exhaust side shaft of the blast furnace blower 100 in the horizontal direction.
In a specific implementation, if the first radial displacement is 130 mm, the second radial displacement is 140 mm, the third radial displacement is 143 mm, and the fourth radial displacement is 145 mm, the second stopping condition is not satisfied; if the first radial displacement is 150 mm, the second radial displacement is 156 mm, the third radial displacement is 166 mm, and the fourth radial displacement is 160 mm, then the second shutdown condition is characterized as being satisfied.
Step S203: and if the second stopping condition is met, controlling the blast furnace blower to stop, and starting the standby air supply system.
Specifically, a backup air supply system (not shown) may be provided for the blast furnace 800, and may communicate with the blast furnace blower 100 through a compressed air pipe (not shown). And if the actual vibration data of a certain blast furnace blower meets the second shutdown condition, controlling the blast furnace blower to shutdown.
When there is at least one blast furnace blower shut down, the total amount of gas entering the blast furnace 800 is reduced, as the amount of total intake reduction is caused by the shut down of the blast furnace blower. Thus, the backup air supply system may be controlled to supply air to the blast furnace 800 to supplement the amount of intake air, which may be the amount of total intake air reduction.
If it is determined that the actual vibration data of a certain blast furnace blower does not meet the second stop condition, starting timing, and re-executing step S202 when the timing time is longer than the preset delay interval: and acquiring actual vibration data of the blast furnace blower based on the reference clock signal to judge whether the second shutdown condition is satisfied next time.
In a specific implementation process, the preset demonstration interval may be set according to the operating state, maintenance condition, operating time length and other factors of each blast furnace blower 100, and the preset delay interval may include 2-4 minutes, for example, 3 minutes, or 2.5 minutes.
