It should be noted that, the COAP system is a system for integrally removing multiple pollutants such as sulfur dioxide, nitrogen oxide, sulfur trioxide, mercury, hydrogen chloride, volatile organic compounds and the like in flue gas by adopting the COAP technology, wherein, as shown in fig. 2 and 4, the COAP system comprises a spray tower (not shown in the drawings), an adsorption tower 1, a plurality of adsorption modules 11 stacked in the adsorption tower 1 and the like, the adsorption modules 11 are internally provided with fillers, low-temperature flue gas enters from an inlet of the adsorption tower 1 and is discharged from an outlet of the adsorption tower 1 after passing through the adsorption modules 11 respectively, and the fillers in the adsorption modules 11 adsorb the pollutants in the low-temperature flue gas when the low-temperature flue gas passes through the adsorption modules 11, thereby removing the pollutants in the flue gas.
If the flue gas temperature in the adsorption tower 1 is too high, the low-temperature requirement in the COAP technology cannot be met, so that the adsorption tower 1 fails and cannot remove pollutants, meanwhile, the too high flue gas temperature in the adsorption tower 1 also easily causes spontaneous combustion of the filler, and the failure of the adsorption modules 11 is caused, so that the flue gas temperature in the adsorption tower 1 can be avoided, and the stable and continuous operation of the adsorption tower 1 is ensured by monitoring the inlet flue gas temperature of the adsorption tower 1, the filler temperature of each adsorption module 11 and the outlet flue gas temperature and performing corresponding alarm information sending and defect eliminating actions.

Meanwhile, when the inlet flue gas moisture is in the first moisture range, the inlet flue gas moisture of the adsorption tower 1 is in a normal state, therefore, when the inlet flue gas temperature is in the first temperature range, the filler temperature of the adsorption module 11 is higher than the second temperature range, and when the outlet flue gas temperature of the adsorption module 11 is higher than the third temperature range, the inside temperature of the adsorption module 11 can be judged to be too high, and the filler has spontaneous combustion problem, so that the operator can be timely prompted to perform accurate cooperation treatment action by sending out the second alarm information of the first degree, the timely defect of the filler overtemperature problem in the adsorption module 11 is ensured, and the stable and continuous operation of the adsorption tower 1 is further ensured.
When the inlet flue gas moisture is in the second moisture range, the inlet flue gas moisture of the adsorption tower 1 is in an abnormal rising state, therefore, when the inlet flue gas temperature is in the first temperature range, the filler temperature of the adsorption module 11 is higher than the second temperature range, and the outlet flue gas temperature of the adsorption module 11 is higher than the third temperature range, the inside of the adsorption module 11 can be judged to generate sulfuric acid and release heat, and the higher heat possibly causes the problem of spontaneous combustion of the filler, therefore, by sending out second alarm information of the second degree, operators can be timely prompted to perform accurate cooperation treatment actions, the timely elimination of the filler overtemperature problem in the adsorption module 11 is ensured, and the stable continuous operation of the adsorption tower 1 is further ensured.
When the temperature of the inlet flue gas is in the first temperature range and the moisture of the inlet flue gas is in the first moisture range, the temperature of the filler of the adsorption module 11 is higher than the second temperature range, and the temperature of the outlet flue gas of the adsorption module 11 is higher than the third temperature range, inert gas is introduced into the adsorption module 11, and the oxygen in the adsorption module 11 can be replaced by the inert gas, so that the filler burnt in the adsorption module 11 is extinguished.
When the temperature of the inlet flue gas is in the first temperature range and the moisture of the inlet flue gas is in the second moisture range, the temperature of the filler of the adsorption module 11 is higher than the second temperature range, and when the temperature of the outlet flue gas of the adsorption module 11 is higher than the third temperature range, inert gas is introduced into the adsorption module 11, so that oxygen and moisture in the adsorption module 11 can be replaced by the inert gas, the adsorption module 11 can be gradually cooled, and the filler possibly burnt in the adsorption module 11 is extinguished.

It can be understood that when the moisture of the inlet flue gas is higher than the first moisture content range, the excessive moisture of the inlet flue gas is indicated to be too large, and the excessive moisture of the inlet flue gas can influence the removal of pollutants from the adsorption tower 1, so that the operation efficiency of the adsorption tower 1 is reduced, and the operation quality is reduced, therefore, the inlet flue gas flow of the adsorption tower 1 is gradually reduced and finally reduced to zero, so that the stop operation of the adsorption tower 1 is realized, the exceeding of the pollutants in the outlet flue gas of the adsorption tower 1 is avoided, and meanwhile, the operation personnel can solve the problem of faults in time.
When the water content of the inlet flue gas is higher than the first water content range and is in the second water content range, a second alarm message of a second degree is sent out, inert gas is introduced into the adsorption module 11, and the inlet flue gas flow of the adsorption tower 1 is gradually reduced until the adsorption tower 1 stops running.
The low-temperature flue gas at the inlet of the adsorption tower 1 comes from cooling of the spray tower, and the flue gas is cooled by 20% calcium chloride solution at the rear section of the spray tower, so that the inlet flue gas of the adsorption tower 1 contains a large amount of calcium chloride, the calcium chloride is easy to adhere to the surface of the filler, the adsorption capacity of the filler is reduced, and the calcium chloride adsorbed on the surface of the filler cannot be removed through the rear-end regeneration tower, so that the filler is subjected to permanent negative influence, and therefore, when the water content of the inlet flue gas is higher than a first water content range, the inlet flue gas flow of the adsorption tower 1 is gradually reduced until the adsorption tower 1 stops running, and defects are eliminated in time, so that the higher adsorption capacity of the filler can be ensured, and the stable continuous running of the adsorption tower 1 is ensured.
The flue gas at the inlet has too much moisture, so that the demisting effect in the spray tower at the front end of the adsorption tower 1 is poor, and therefore, after the adsorption tower 1 stops running, operators can carry out overhauling such as dredging of a demister in the spray tower.
Through reducing the inlet flue gas flow of the adsorption tower 1 to zero, the first flow, the second flow and the third flow are sequentially passed through, so that the whole inlet flue gas moisture of different flow grades of the adsorption tower 1 can be monitored, misjudgment of the inlet flue gas moisture of the adsorption tower 1 is effectively reduced, accurate monitoring of the inlet flue gas moisture of the adsorption tower 1 is realized, and meanwhile, shutdown buffering of the adsorption tower 1 is realized through the arrangement of the first flow, the second flow and the third flow, thereby reducing the failure rate of the adsorption tower 1 and ensuring stable operation of the adsorption tower 1 after the defect elimination.
The specific values of the first flow, the second flow and the third flow can be set according to actual needs, which is not limited.
The collection mode of the inlet flue gas flow of the adsorption tower 1 can be set according to actual needs, which is not limited, and at least one flow sensor is arranged at the inlet of the adsorption tower 1 to collect the inlet flue gas flow of the adsorption tower 1 by using the flow sensor.
