Following examples are implemented under premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model are not limited to following embodiment.In following embodiment, method therefor is ordinary method if no special instructions.
[embodiment 1]
As shown in Figure 1, in the present embodiment, comprise G1 ~ G6 totally 6 gas blowers 1, respectively by S1 ~ S4 totally 4 female pipes 2 of air-supply be connected with 4 blast furnaces, gas blower 1 exports and is connected on branch road is respectively equipped with electronic trip valve with female pipe 2 of blowing.
Main air dispensation system 3 and air dispensation system 4 for subsequent use adopt the female pipe 5 of three wind turnings to be communicated with S1 ~ S4, be directly be communicated with between wherein S1 and S3 ~ S4, the female pipe 5 of wind turning of its linkage section is provided with a pneumatic quick-opening valve 6 and an electronic trip valve 7, and is indirect communication between S2 and S3, between S2 and S4 and between S3 and S4.In the air feed system only having an air dispensation system, in order to ensure the female pipe 5 of each road wind turning with blow being communicated with between female pipe 2, the female pipe 5 of each road wind turning and blow between female pipe 2 and can only adopt direct-passing mode.But after adopting the air dispensation system of redundant configuration, wind turning female pipe 5 in each road also can adopt indirect connections to be communicated with blowing between female pipe 2, the advantage of this mode of communicating facilitates gas blower 1 to arrange, and pipeline connecting mode is simple, use valve quantity few, gas blower 1 can realize increase and decrease as required easily, and need not redesign the wiring position of air dispensation system.
In the present embodiment, main air dispensation system 3 connects the blow female pipe 5 of wind turning of female pipe 2 of S1 and S2 and is provided with pneumatic quick-opening valve 6 (Q3), electronic trip valve 7 (D3); Connect S1 and S3 blow female pipe 2 wind turning mother pipe 5 be provided with pneumatic quick-opening valve 6 (Q2), electronic trip valve 7 (D2); Connect S1 and S4 blow female pipe 2 wind turning mother pipe 5 be provided with pneumatic quick-opening valve 6 (Q1), electronic trip valve 7 (D1); And need between S2 and S3 by be provided with Q2, D2 and Q3, D3 female pipe 5 indirect communication of two sections of wind turnings, need between S2 and S4 by be provided with Q2, D2 and Q1, D1 female pipe 5 indirect communication of two sections of wind turnings, need between S2 and S4 by be provided with Q3, D3 and Q1, D1 female pipe 5 indirect communication of two sections of wind turnings.
Air dispensation system 4 for subsequent use connects the blow female pipe 5 of wind turning of female pipe 2 of S1 and S2 and is provided with pneumatic quick-opening valve 6 (Q) 4, electronic trip valve 7 (D4); Connect S1 and S3 blow female pipe 2 wind turning mother pipe 5 be provided with pneumatic quick-opening valve 6 (Q5), electronic trip valve 7 (D5); Connect S1 and S4 blow female pipe 2 wind turning mother pipe 5 be provided with pneumatic quick-opening valve 6 (Q6), electronic trip valve 7 (D6); Its blow connected relation between female pipe 2 and main air dispensation system 3 are principle of uniformity, do not add repeat at this.
The Controlling System of the present embodiment as shown in Figure 2, background monitoring device comprises an engineer station 11 and two active stations 10 in parallel, each active station 10 is connected with the CPU of main PLC or PL8C for subsequent use by host change or backup switch 9 with engineer station 11, is connected between main PLC with PLC8 for subsequent use by communication module.In Controlling System, corresponding network and power supply also adopt redundant configuration.
The principle of work of air dispensation system is existing in other documents published to be introduced in detail, is described in this feature for a kind of redundancy air dispensation system of the utility model:
For air dispensation system shown in Fig. 1, G1 ~ G4 gas blower can be selected to be working fan, G1 ~ G4 gas blower is standby blower fan, and stand-by fan can realize wind turning function, also can replace other main blower work when overhauling.When blast furnace air supply system all normal time, gas blower 1G1 ~ G4 blows respectively to 1 ~ 4# blast furnace of correspondence, now, G5 ~ G6 gas blower 1, main air dispensation system 3 and air dispensation system for subsequent use 4 do not work, electronic trip valve 7 on the female pipe 5 of main air dispensation system 3 and air dispensation system for subsequent use 4 wind turning is normally open valve, and pneumatic quick-opening valve 6 processes off state.When certain main blower 1 that Controlling System detects in air feed system automatically break down can not meet blast furnace air feed needs time, the air-supply total valve of the automatic disengagement failure main blower 1 of Controlling System, the main air dispensation system 3 of emergency start simultaneously, the pneumatic quick-opening valve 6 of the female pipe 5 of now main air dispensation system 3 wind turning is opened rapidly, main air dispensation system 3 automatic fanning.Pneumatic quick-opening valve 6 as main air dispensation system 3 is not opened in setting-up time (as 3S), then air dispensation system 4 for subsequent use starts automatically, opens corresponding pneumatic quick-opening valve 6 and realizes automatic fanning.In like manner, when master operating station 10, host change 9 or main PLC8 break down, corresponding standby operation station 10, backup switch 9 and PLC8 for subsequent use can start work automatically, guarantee under any circumstance, and system all can realize two-way wind turning function.
Except in Control Room by except active station 10 remote monitoring; Gas blower 1, main air dispensation system 3 and air dispensation system for subsequent use 4 all can off-line operations on the other operation box of machine, even if under network failure or Controlling System situation all out of service, and still can by manually carry out operation of equipment on the other operation box of machine.
