Embodiment
The utility model is described in detail below in conjunction with accompanying drawing.As shown in Figure 1 and Figure 2.
Embodiment：A kind of fire safety control system for exhaust gas apparatus, including：
The branch pipe(tube) 1 of working region is arranged on, several branch detectors 3 are provided with branch pipe(tube) 1；
For the main pipeline 2 for connecting branch pipe(tube) 1, several main detectors 4 are provided with main pipeline 2；
Main exhaust 10, for waste gas to be discharged, main exhaust 10 is connected with blower fan 11；
Frpipe 6, for main exhaust 10 to be connected with main pipeline 2；And before being provided between Frpipe 6 and main pipeline 2 certainly
Dynamic closing valve 8；
Control device 12, it is connected respectively with main detector 4, branch detector 3, blower fan 11 and the signal of preceding self closing valve 8.
When main detector 4 or branch detector 3 are detected with flame or temperature is higher or when situation is abnormal, control device 12 is controlled
Self closing valve 8, blower fan 11 are closed before system.
The technical program can be applied in plant gas equipment, and in the presence of blower fan 11, branch pipe(tube) 1 is by working region
Gas suction, and enter main pipeline 2；Main pipeline 2 and branch pipe(tube) 1 are generally located on the inside of floor, and main exhaust 10 passes through
Whole floor is worn, positioned at the outside of working region, the wall 5 of Frpipe 6 through floor is connected with main exhaust 10；Main exhaust
10 are connected by Frpipe 6 with main pipeline 2, and gas is entered in main exhaust 10 by Frpipe 6, and passes through main exhaust 10
Discharge, waste gas can be discharged into processing pond or combustion chamber etc.；It can also collect.Main exhaust 10 passes through Frpipe 6 and every layer of supervisor
Road 2 connects.After operation interval or the indoor generation condition of a fire, after main detector 4 or branch detector 3 detect, control is sent information to
Device 12 processed.Main detector 4, branch detector 3 can be temperature inductor, gas detector or smoke detector or thermistor
Deng；Control device 12 can be PLC control system, single-chip microcomputer, can also be central processing unit etc.；Control device 12 judges there is fire
After calamity occurs, self closing valve 8 sends control signal forward immediately, and preceding self closing valve 8 is closed and blower fan 11 is closed.Due to
Preceding self closing valve 8 is closed, and passage is obstructed, and flame can not extend, and at most burns branch pipe(tube) 1, main pipeline 2.It is and preceding automatic
