Then pass through third trip valve 71, the main effect is automatic chain protection action when too high or too low of pressure, self-closing, guarantee safety, pass through third blowoff valve 72, the main effect is also when exhaust pressure is too high, can in time open automatically and release pressure guarantee safety, also have interlocking relation with pressure simultaneously, when the exhaust pressure in the front of the furnace is too high or too low, this valve can open automatically, play the safety protection effect, pass through fourth trip valve 73 again, the main effect is automatic chain protection action when too high or too low of pressure with preceding third trip valve 71, self-closing, guarantee safety, it is the chain connection relation with third trip valve 71, chemical industry waste gas gets into circulating fluidized bed boiler's furnace 10 through boiler's combustor 11 and burns at last.
There is a branch pipe on the first exhaust gas pipe 21 before the furnace, i.e. the second exhaust gas pipe 22, before chemical waste gas gets into circulating fluidized bed boiler burning, in order to guarantee chemical waste gas safe burning, so design this branch, when chemical waste gas gets into before the furnace, close the fifth blowoff valve 75, the fifth trip valve 74 and the sixth trip valve 76 are opened, go deep into circulating fluidized bed boiler's furnace 10 with burning torch 12, and strike sparks, send chemical waste gas into circulating fluidized bed boiler, when burning torch 12 is lighting on waste gas, flame safety interlock protection device 30 can detect out the flame signal, for the success of igniting this moment, waste gas has burnt. If there is no flame signal, the ignition fails, and the flame safety interlock protection device 30 will simultaneously close the fifth and sixth shut-off valves 74, 76, shut off the gas supply, and open the fifth exhaust valve 75. And re-igniting according to the steps until the re-ignition is successful.
The pipe diameter of the second waste gas pipeline 22 is smaller than that of the first waste gas pipeline 21, the smaller the pipe diameter is, the higher the safety is during ignition, so when air supply and ignition are performed, the second waste gas pipeline 22, namely the ignition gun 12 on the branch is used for ignition, after chemical waste gas is confirmed to be combusted, the first waste gas pipeline 21, namely the main path, is put into operation, the flow is increased as required, and meanwhile, the ignition supply of the branch can be quitted.
The chemical waste gas of suitable pressure after the pressure regulation main valve 61 through waste gas conveying main 23 adjusts is through open first trip valve 63 and second trip valve 65, at this moment the burning torch 12 gets into in the furnace 10, and ignite by the high energy lighter, then fifth trip valve 74 and sixth trip valve 76 open simultaneously, third trip valve 71 and fourth trip valve 73 close, if flame signal appears, then the waste gas burning is successful, it is normal when observing the waste gas burning, can open third trip valve 71 and fourth trip valve 73 when waste gas pressure is normal, close third blowoff valve 72, flame signal is normal then the waste gas is put into operation the burning and is successful. If the commissioning is abnormal and the flame signal is absent, the commissioning is resumed according to the starting step until the commissioning combustion is successful.
Through a plurality of tests, the waste gas generated by the chemical ammonia synthesis device described in the background technology is adopted, under the condition that a circulating fluidized bed boiler absorbs 1200 square chemical waste gas per hour, 1.59 tons of standard coal can be saved per hour, and after the combusted gas reacts with sulfur dioxide and ammonia water generated by coal combustion in the hearth 10, the combusted gas is mixed with fly ash and bottom slag generated by coal combustion and then reaches the standard to be discharged, thereby meeting the environmental protection requirement of national requirements. When the chemical waste gas meets open fire in the circulating fluidized bed boiler, the bed temperature in the hearth is more safe when burning at more than 800 ℃, and the chemical waste gas can be fully mixed with materials in the boiler and can be completely burnt.
