Fig. 1 is structural representation of the present invention;
Fig. 2 is the wind turning schematic flow sheet.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
The wind turning security system, include master control set, air feed main pipe line I for blast furnace I air feed, the air feed main pipe line II of blast furnace II air feed, the air feed main pipe line III of blast furnace III air feed, it is the blower fan I of three blast furnace air feeds, blower fan II and blower fan III, be provided with the wind turning pipeline between any two air feed main pipe lines, be provided with a wind turning valve at the wind turning pipeline, air feed main pipe line I is by blower fan I air feed, air feed main pipe line II is by blower fan II air feed, air feed main pipe line III is by blower fan III air feed, in the blower fan I, the air outlet of blower fan II and blower fan III is provided with a vacuum breaker, in air feed main pipe line I, air feed main pipe line II and air feed main pipe line III are provided with the wind pressure monitoring device, the wind pressure monitoring device is sent to master control set with the data that collect, three typhoon machines, the condition monitoring end of wind turning valve and vacuum breaker is connected with master control set, and the instruction output end of master control set is connected with the wind turning valve with each vacuum breaker respectively.
Concrete control wind turning method is:
1) judge whether fan trouble, can't send wind, if, then turn to step 3), if not, then turn to step 2);
2) blast of three air feed main pipe lines of monitoring judges whether within preset range, if not, then turn to step 3), if then finish;
3) determine the air feed main pipe line at fault blower fan place or the unusual air feed main pipe line of blast be wind turning to picture, whether be judged as wind turning closed to the fan outlet vacuum breaker of picture air feed, if, then change step 4) over to, if not, then finish;
4) judge whether wind turning handles armed state to wind turning valve between picture and other air feed main pipe line, if there is more than one wind turning valve to be ready, then turns to step 5), if do not have, then finishes;
5) judge whether the air feed main pipe line that the wind turning valve be ready connects meets the wind turning condition, if meet, then opens a wind turning valve according to default wind turning sequencing, carries out the wind turning operation, if do not meet, then finishes.
The condition of wind turning described in the step 5) is: wind turning is lower than preset value a to the blast of picture, and whether other air feed main pipe line is higher than preset value a, and the air feed main pipe line that is higher than preset value a meets the wind turning condition.
Preset value a is 0.2Mpa.
The blast that default wind turning sequencing described in the step 5) is applicable to a plurality of wind turning main pipe lines is during greater than preset value a, and selecting one of them wind turning main pipe line sequentially is that wind turning is to the picture wind turning.
The air outlet of described blower fan I, blower fan II and blower fan III all is connected to air feed main pipe line I, air feed main pipe line II and air feed main pipe line III by three air supply ducts.Every typhoon machine all can increase the air feed handiness of system for any air feed main pipe line air feed at maintenance time.
Be provided with three wind pressure monitoring devices in air feed main pipe line I, air feed main pipe line II and air feed main pipe line III, the wind pressure monitoring device lays respectively at the interface position place of air supply duct and three air feed main pipe lines.In order accurately to judge whether the blast of air feed main pipe line is normal, a wind pressure monitoring device can be set in each air port.
Be provided with a switching valve at air supply duct.When blower fan need be safeguarded, cut off blower fan to the wind path of air feed main pipe line by closing switching valve.
Described system also includes the blower fan IV, and the blower fan IV is connected respectively to air feed main pipe line I, air feed main pipe line II and air feed main pipe line III by three air supply ducts.The blower fan IV is stand-by fan, when typhoon machine maintenance or fault, is the wind turning of air feed main pipe line by the wind turning valve temporarily, guarantees can not break wind, opens the blower fan IV again, makes the blast furnace works better.
Wind turning pipeline at each wind turning valve two ends is respectively arranged with a segregaion valve.By cut-offfing segregaion valve, can determine whether the wind turning valve devotes oneself to work.
Described vacuum breaker is provided with travel switch, and travel switch is connected with master control set by annular network of communication.Before wind turning, must guarantee blower fan and need the wind path between the air feed main pipe line of wind turning to disconnect, pour in down a chimney otherwise blast in wind turning, can occur.
