Valve 1091 for prevent cooler 203 break down when, flue gas blowback condenses to form tar after pollute hot air apparatus 106, and
Temperature is relatively high at work for hot air apparatus 106, and the tar that is easy to ignite causes fire.Pneumatic stopping valve 1092 is used in each branch
Controller can control when the temperature that the temperature sensor in the exit of reactor 102 is shown exceeds predetermined threshold closes gas in time
Dynamic shut-off valve 1092, so that the first pipeline 110 and 112 inside of second pipe and air exclusion, avoid the generation of fire.It cuts manually
Only valve 1093 is used to occur in pipeline that each shut-off valve to be turned off manually when fire, further such that pipeline inside and air exclusion.
It is off state when fire-fighting 1094 normal condition of water filling port, when pneumatic stopping valve 1092 is closed, controller is according to second temperature
Temperature in the second pipe 112 of sensor measurement opens the valve of fire-fighting water filling port 1094, the valve of fire-fighting water filling port 1094
After door is opened, fire water is injected into second pipe 112 and is put out a fire.
In aluminium anode assembly room during producing anode, aluminium anode assembly room bitumen flue gas processing system
100 operating procedure is as follows:
When aluminium anode assembly room produces, before the starting of kneading machine 202, pre-cooling deduster 1051, air-introduced machine
1052 and according to air quantity open it is each receive hood outlet semi-open type valve (in addition to the receipts on feed hopper 206 and molding machine 205
The semi-open type valve of petticoat pipe is in off state, because feed hopper 206 and molding machine 205 are in work original state without material).?
After kneading machine 202 starts, carbon dust delivery section 107 and hot air apparatus 106 are worked normally, and controller is according to each branch reactor
The exhaust gas volumn of smoke detectors measurement and the humid control carbon dust delivery section 107 of humidity sensor measurement of 102 inlet are every
A branch reactor 102 provides the carbon dust of corrresponding quality, the air flow sensor control on bye-pass where each receipts petticoat pipe
Make the aperture of the corresponding semi-open type valve for receiving petticoat pipe of each equipment.In the present embodiment, by useless paste belt 207, feed hopper 206
Molding machine region is used as with molding machine 205.Before initial production, thickener is more from the material come out in cooler 203, vibration
Initial thickener is conveyed to useless paste belt 207 by feed hopper 204, and the exhaust gas volumn main source in molding machine region is useless paste belt
At 207.Therefore, the semi-open type valve on the useless paste belt 207 in controller control molding machine region is opened, and controls molding machine region
Feed hopper 206 and molding machine 205 on receipts petticoat pipe semi-open type valve close；During normal production, it is come out from cooler 203
Material be normal material, material is conveyed to feed hopper 206 by vibratory feed unit 204, and feed hopper 206 is respectively each molding machine
205 feedings, therefore, during normal production, controller controls the semi-open type valve of the receipts petticoat pipe on the feed hopper 206 in molding machine region
It opens, and is the sequence of each 205 feeding of molding machine according to feed hopper 206, opening on the molding machine 205 being fed is
The semi-open type valve for receiving petticoat pipe greatly increases air-introduced machine 1052 to largely reduce the air quantity in molding machine region
Negative pressure utilization rate.And for each equipment, all setting receipts petticoat pipe carries out receipts cigarette to the utility model, also solves molding machine area
Domain flue gas is difficult to the problem of collecting.
During production, controller is according to the first temperature sensor 108 of the inlet that dust-extraction unit 105 is arranged in
The hot wind input quantity of hot air apparatus 106 is controlled with the temperature of the temperature sensor measurement in the exit of each branch reactor 102,
When the smoke temperature value of each temperature sensor measurement is less than given threshold, controller control hot air apparatus 106 provides more hot winds,
To improve the smoke temperature in pipeline, so that the vapor and flue gas in pipeline are always gaseous state.Controller is reacted according to each branch
The exhaust gas volumn of the corresponding smoke detectors measurement of device and the humid control carbon dust delivery section 107 of humidity sensor measurement are each
Road reactor conveys the carbon dust of predetermined quality, adsorbs flue gas and vapor in pipeline in advance.
Above embodiment is the preferred case of the utility model, is not intended to limit the protection scope of the utility model.
