[0037] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present disclosure, and cannot be understood as a limitation of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0038] As Figure 1 and Figure 2 shown, the present disclosure proposes an adsorption tower monitoring method of a COAP (Cold Oxidation Absorption Process) system, comprising:

[0039] S1: collect the inlet flue gas temperature of the adsorption tower 1;

[0040] S2: collect the packing temperature and the outlet flue gas temperature of each adsorption module 11;

[0041] S3: compare the inlet flue gas temperature with the first temperature range, the packing temperature with the second temperature range, and the outlet flue gas temperature with the third temperature range;

[0042] S4: issue corresponding alarm information according to the comparison result, and perform corresponding defect elimination action.

[0043] It can be understood that by collecting the inlet flue gas temperature of the adsorption tower 1 and comparing the inlet flue gas temperature with the first temperature range, the monitoring of the inlet flue gas temperature of the adsorption tower 1 can be realized, by collecting the packing temperature of each adsorption module 11 and comparing the packing temperature with the second temperature range, the monitoring of the packing temperature of the adsorption module 11 in the adsorption tower 1 can be realized, by collecting the outlet flue gas temperature of each adsorption module 11 and comparing the outlet flue gas temperature with the third temperature range, the monitoring of the outlet flue gas temperature of the adsorption module 11 in the adsorption tower 1 can be realized, and at the same time, according to the comparison result of the inlet flue gas temperature with the first temperature range, the packing temperature with the second temperature range, and the outlet flue gas temperature with the third temperature range, corresponding alarm information is issued and corresponding defect elimination action is performed, which can timely solve the fault problem of the adsorption tower 1, ensure the continuous operation of the adsorption tower 1, avoid the problem that the removal of pollutants cannot meet the standard, and thus improve the operation efficiency of the adsorption tower 1 and ensure the stable operation of the COAP system.

[0044] It should be noted that the COAP system is a system that uses COAP technology to integrally remove multiple pollutants such as sulfur dioxide, nitrogen oxides, sulfur trioxide, mercury, hydrogen chloride, and volatile organic compounds in flue gas. Figure 2 and Figure 4 As shown in FIGS. 1 and 2, the COAP system includes a spray tower (not shown in the figure), the adsorption tower 1, a plurality of adsorption modules 11 stacked in the adsorption tower 1, etc. The adsorption module 11 is provided with packing, low-temperature flue gas enters from the inlet of the adsorption tower 1 and is discharged from the outlet of the adsorption tower 1 after passing through the plurality of adsorption modules 11, and when the low-temperature flue gas passes through the adsorption module 11, the packing in the adsorption module 11 adsorbs the pollutants in the low-temperature flue gas, thereby realizing the removal of pollutants in the flue gas.

[0045] If the flue gas temperature in the adsorption tower 1 is too high, the low temperature requirement in the COAP technology cannot be met, the adsorption tower 1 fails and cannot remove the pollutants, and at the same time, the high flue gas temperature in the adsorption tower 1 is easy to cause the self-ignition of the filler, causing the failure of the adsorption module 11. Therefore, by monitoring the inlet flue gas temperature of the adsorption tower 1, the filler temperature and the outlet flue gas temperature of each adsorption module 11, and issuing corresponding alarm information and performing defect elimination actions, the abnormal flue gas temperature in the adsorption tower 1 can be avoided, and the stable and continuous operation of the adsorption tower 1 is ensured.

[0046] At the same time, oxygen, water and sulfur dioxide in the flue gas are easy to react to generate sulfuric acid and release a large amount of heat, which is also easy to cause the self-ignition of the activated carbon.

[0047] The type of the filler in the adsorption module 11 can be set according to actual needs, and is not limited, for example, the filler can be activated carbon.

[0048] The collection method of the inlet flue gas temperature of the adsorption tower 1 can be set according to actual needs, and is not limited, for example, at least one first temperature sensor is arranged at the inlet of the adsorption tower 1 to collect the inlet flue gas temperature of the adsorption tower 1 by using the first temperature sensor.

[0049] The collection method of the filler temperature of the adsorption module 11 can be set according to actual needs, and is not limited, for example, at least one second temperature sensor is arranged in the adsorption module 11 to collect the filler temperature of the adsorption module 11 by using the second temperature sensor.

[0050] The collection method of the outlet flue gas temperature of the adsorption module 11 can be set according to actual needs, and is not limited, for example, at least one third temperature sensor is arranged at the outlet of the adsorption module 11 to collect the outlet flue gas temperature of the adsorption module 11 by using the third temperature sensor.

[0051] Each adsorption module 11 is provided with at least one second temperature sensor and at least one third temperature sensor, for example, when the adsorption module 11 is sixteen, at least sixteen second temperature sensors and third temperature sensors are provided.

[0052] The inlet flue gas temperature of the adsorption tower 1 needs to be in the first temperature range, and the specific value of the first temperature range can be set according to actual needs, and is not limited, for example, the first temperature range can be-15 degrees to-10 degrees.

[0053] The filler temperature of the adsorption module 11 needs to be in the second temperature range, and the specific value of the second temperature range can be set according to actual needs, and is not limited, for example, the second temperature range can be-10 degrees to-5 degrees.

[0054] The outlet flue gas temperature of the adsorption module 11 needs to be in a third temperature range, and the specific value of the third temperature range can be set according to actual needs, and the third temperature range is not limited, for example, the third temperature range can be -5 degrees to 0 degrees.

[0055] In some embodiments, corresponding alarm information is issued according to the result of the comparison, and corresponding defect elimination actions are performed, including:

[0056] 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, a first alarm information is issued, and inert gas is introduced into the adsorption module 11 to eliminate the filler over-temperature in the adsorption module 11.

[0057] It can be understood that when the inlet flue gas temperature is in the first temperature range, it indicates that the inlet flue gas temperature of the adsorption tower 1 is in a normal state, when 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, it indicates that the filler temperature and the outlet flue gas temperature of the adsorption module 11 are in an abnormal high state, at this time, it can be judged that the internal temperature of the adsorption module 11 is too high, and the filler may have a self-ignition problem, therefore, by issuing the first alarm information, the operating personnel can be prompted in time to perform corresponding cooperation processing, and at the same time, by introducing inert gas into the adsorption module 11, the oxygen, moisture and the like in the adsorption module 11 can be replaced to cool down the inside of the adsorption module 11 and extinguish the possible burning filler. Thus, the filler over-temperature problem in the adsorption module 11 is eliminated in time, and the stable and continuous operation of the adsorption tower 1 is ensured.

[0058] It should be noted that the first alarm information is used to prompt the operating personnel, and the issuing mode of the first alarm information can be set according to actual needs, and the first alarm information is not limited, for example, the first alarm information can be sound information, light information, sound and light information, etc., and the first alarm information can be issued through a sound alarm, a light alarm, a sound and light alarm, etc.

[0059] The mode of introducing inert gas into the adsorption module 11 can be set according to actual needs, and the mode of introducing inert gas into the adsorption module 11 is not limited, for example, the adsorption tower 1 includes a gas storage tank, the gas storage tank stores compressed inert gas, the gas outlet end of the gas storage tank is connected with the gas inlet end of each adsorption module 11, and each adsorption module 11 is provided with a switch valve. 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 switch valve is opened, and the inert gas in the gas storage tank enters the adsorption module 11 to cool down the adsorption module 11 and extinguish the possible burning filler in the adsorption module 11.

[0060] The specific type of inert gas can be set according to actual needs, and is not limited, for example, the inert gas can be nitrogen.

[0061] In some embodiments, the adsorption tower monitoring method further comprises:

[0062] Collecting the inlet flue gas moisture of the adsorption tower 1;

[0063] Comparing the inlet flue gas moisture with the first moisture range and comparing the inlet flue gas moisture with the second moisture range, wherein the first moisture range is lower than the second moisture range.

[0064] When the inlet flue gas moisture is within the first moisture range, a first degree of second alarm information is issued;

[0065] When the inlet flue gas moisture is within the second moisture range, a second degree of second alarm information is issued.

[0066] It can be understood that by collecting the inlet flue gas moisture of the adsorption tower 1 and comparing the inlet flue gas moisture with the first moisture range and the inlet flue gas moisture with the second moisture range, the inlet flue gas moisture of the adsorption tower 1 can be monitored, and further combined with the monitoring of the inlet flue gas temperature of the adsorption tower 1 and the packing temperature and outlet flue gas temperature of the adsorption module 11, the cause of the failure in the adsorption module 11 can be accurately determined, and the operating personnel can more accurately and systematically monitor the adsorption tower 1.

[0067] At the same time, when the inlet flue gas moisture is within the first moisture range, it indicates that the inlet flue gas moisture of the adsorption tower 1 is in a normal state, and thus, when the inlet flue gas temperature is within the first temperature range, and the packing 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, it can be determined that the internal temperature of the adsorption module 11 is too high, and the packing has a self-ignition problem. Therefore, by issuing the first degree of second alarm information, the operating personnel can be prompted in time to take precise cooperative handling actions, ensuring that the packing over-temperature problem in the adsorption module 11 is promptly eliminated, and thus ensuring the stable and continuous operation of the adsorption tower 1.

[0068] When the inlet flue gas moisture is in the second moisture range, it indicates that the inlet flue gas moisture of the adsorption tower 1 is in an abnormally high state. Therefore, when the inlet flue gas temperature is in the first temperature range, the packing 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, it can be judged that sulfuric acid is generated inside the adsorption module 11 and heat is released, and the higher heat can cause the problem of self-ignition of the packing. Therefore, by issuing the second alarm information of the second degree, the working personnel can be prompted in time to perform accurate cooperation processing actions, so as to ensure that the packing over-temperature problem in the adsorption module 11 is timely eliminated, and the stable and continuous operation of the adsorption tower 1 is ensured.

[0069] It should be noted that when the inlet flue gas temperature is in the first temperature range, the inlet flue gas moisture is in the first moisture range, the packing 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 inert gas is introduced into the adsorption module 11, which can replace the oxygen in the adsorption module 11 with the inert gas, thereby extinguishing the burning packing in the adsorption module 11.

[0070] When the inlet flue gas temperature is in the first temperature range, the inlet flue gas moisture is in the second moisture range, the packing 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 inert gas is introduced into the adsorption module 11, which can replace the oxygen and moisture in the adsorption module 11 with the inert gas, gradually cool the adsorption module 11, and extinguish the possible burning packing in the adsorption module 11.

[0071] The inlet flue gas moisture of the adsorption tower 1 needs to be in the first moisture range. The specific value of the first moisture range can be set according to actual needs, and no limitation is made thereto. For example, the first moisture range can be less than 70 mg / Nm 3 .

[0072] The collection method of the inlet flue gas moisture of the adsorption tower 1 can be set according to actual needs, and no limitation is made thereto. For example, at least one flue gas moisture instrument is arranged at the inlet of the adsorption tower 1 to collect the inlet flue gas moisture of the adsorption tower 1 by using the flue gas moisture instrument.

[0073] The specific value of the second moisture range can be set according to actual needs, and no limitation is made thereto. For example, the second moisture range can be 70 mg / Nm 3 to 200 mg / Nm 3 .

[0074] The second alarm information is used to prompt the operating personnel. The sending mode of the second alarm information can be set according to actual needs, and no limitation is made in this regard. For example, the second alarm information can be sound information, light information, sound and light information, etc. The sending of the second alarm information can be through a sound alarm, a light alarm, a sound and light alarm, etc. Among them, the second alarm information of the first degree is different from the second alarm information of the second degree. The alarm information of different degrees can be sound of different sizes, light of different brightnesses or different frequencies, etc. No limitation is made in this regard.

[0075] In some embodiments, the adsorption tower monitoring method further comprises:

[0076] When the inlet flue gas moisture is higher than the first moisture content range, the inlet flue gas flow of the adsorption tower 1 is sequentially reduced to a first flow rate, a second flow rate and a third flow rate, until the inlet flue gas flow of the adsorption tower 1 is zero, wherein the first flow rate is greater than the second flow rate, the second flow rate is greater than the third flow rate, and the third flow rate is greater than zero.

[0077] It can be understood that when the inlet flue gas moisture is higher than the first moisture content range, it means that the inlet flue gas moisture is too large. The excessive inlet flue gas moisture will affect the removal of pollutants by the adsorption tower 1, resulting in a decrease in the operating efficiency and quality of the adsorption tower 1. Therefore, by gradually reducing the inlet flue gas flow of the adsorption tower 1 and finally reducing it to zero, the operation of the adsorption tower 1 is stopped, avoiding the exceeding of pollutants in the outlet flue gas of the adsorption tower 1, and facilitating the timely solution of fault problems by the operating personnel.

[0078] It should be noted that when the inlet flue gas moisture is higher than the first moisture content range and within the second moisture content range, the second alarm information of the second degree is sent and the inert gas is introduced into the adsorption module 11, and at the same time, the inlet flue gas flow of the adsorption tower 1 is gradually reduced until the adsorption tower 1 stops operating.

[0079] The low-temperature flue gas at the inlet of the adsorption tower 1 comes from the cooling of the spray tower. The rear section of the spray tower uses 20% calcium chloride solution to cool the flue gas, so that the inlet flue gas of the adsorption tower 1 contains a large amount of calcium chloride. Calcium chloride is easy to adhere to the surface of the filler, causing the adsorption capacity of the filler to decrease. Moreover, the calcium chloride adsorbed on the surface of the filler cannot be removed by the rear-end regeneration tower, which has a permanent negative impact on the filler. Therefore, when the inlet flue gas moisture is higher than the first moisture content range, the inlet flue gas flow of the adsorption tower 1 is gradually reduced until the adsorption tower 1 stops operating, and timely defect elimination is performed, which can ensure a high adsorption capacity of the filler and further ensure stable and continuous operation of the adsorption tower 1.

[0080] Among them, the excessive inlet flue gas moisture means that the demisting effect in the spray tower at the front end of the adsorption tower 1 is poor. Therefore, after the adsorption tower 1 stops operating, the operating personnel can perform maintenance such as dredging of the demister in the spray tower.

[0081] By sequentially passing through the first flow rate, the second flow rate and the third flow rate before reducing the inlet flue gas flow rate of the adsorption tower 1 to zero, the overall can monitor the inlet flue gas moisture of the adsorption tower 1 at different flow rates, thereby effectively reducing the misjudgment of the inlet flue gas moisture of the adsorption tower 1, realizing accurate monitoring of the inlet flue gas moisture of the adsorption tower 1, and at the same time, through the setting of the first flow rate, the second flow rate and the third flow rate, realizing the shutdown buffer of the adsorption tower 1, thereby reducing the failure rate of the adsorption tower 1 and ensuring the stable operation of the adsorption tower 1 after defect elimination.

[0082] The specific values of the first flow rate, the second flow rate and the third flow rate can be set according to actual needs, and no limitation is made thereto.

[0083] The collection method of the inlet flue gas flow rate of the adsorption tower 1 can be set according to actual needs, and no limitation is made thereto. For example, at least one flow rate sensor is arranged at the inlet of the adsorption tower 1 to collect the inlet flue gas flow rate of the adsorption tower 1 by using the flow rate sensor.

[0084] In some embodiments, corresponding alarm information is issued according to the comparison result, and corresponding defect elimination actions are performed, including:

[0085] When the inlet flue gas temperature is higher than the first temperature range, a third alarm information is issued, and the inlet flue gas flow rate of the adsorption tower 1 is sequentially reduced to a fourth flow rate, a fifth flow rate and a sixth flow rate until the inlet flue gas flow rate of the adsorption tower 1 is zero, wherein the fourth flow rate is greater than the fifth flow rate, the fifth flow rate is greater than the sixth flow rate, and the sixth flow rate is greater than zero.

[0086] It can be understood that when the inlet flue gas temperature is higher than the first temperature range, it means that the inlet flue gas temperature of the adsorption tower 1 is too high. Therefore, by gradually reducing the inlet flue gas flow rate of the adsorption tower 1 and finally reducing it to zero, the operation of the adsorption tower 1 is stopped, avoiding the over-standard of pollutants in the outlet flue gas of the adsorption tower 1. At the same time, through the issuance of the third alarm information, the operating personnel can be prompted to take accurate handling actions in time, ensuring that the fault problem is eliminated in time, and thereby ensuring the stable and continuous operation of the adsorption tower 1.

[0087] It should be noted that the low-temperature flue gas at the inlet of the adsorption tower 1 comes from the cooling of the spray tower. When the inlet flue gas temperature is too high, it means that the cooling efficiency of the spray tower has decreased. Therefore, after the adsorption tower 1 stops running, the operating personnel can perform maintenance on the spray system in the spray tower.

[0088] The third alarm information is used to prompt the operating personnel. The issuance method of the third alarm information can be set according to actual needs, and no limitation is made thereto. For example, the third alarm information can be sound information, light information, sound and light information, etc. The issuance of the third alarm information can be through a sound alarm, a light alarm, a sound and light alarm, etc.

[0089] By sequentially passing through the fourth flow rate, the fifth flow rate and the sixth flow rate before reducing the inlet flue gas flow rate of the adsorption tower 1 to zero, the overall can monitor the inlet flue gas temperature of the adsorption tower 1 at different flow rates, thereby effectively reducing the misjudgment of the inlet flue gas temperature of the adsorption tower 1, achieving accurate monitoring of the inlet flue gas temperature of the adsorption tower 1. At the same time, through the setting of the fourth flow rate, the fifth flow rate and the sixth flow rate, the shutdown buffer of the adsorption tower 1 is realized, thereby reducing the failure rate at the adsorption tower 1 and ensuring the stable operation of the adsorption tower 1 after defect elimination.

[0090] The specific values of the fourth flow rate, the fifth flow rate and the sixth flow rate can be set according to actual needs, and no limitation is made thereto.

[0091] In some embodiments, the adsorption tower monitoring method further comprises:

[0092] Collecting the outlet flue gas pollutant concentration of the adsorption tower 1;

[0093] Comparing the outlet flue gas pollutant concentration with the concentration range.

[0094] When the inlet flue gas temperature is within the first temperature range, the filler temperature of the adsorption module 11 is lower than the second temperature range, the outlet flue gas temperature of the adsorption module 11 is lower than the third temperature range, and the outlet flue gas pollutant concentration is higher than the concentration range, a fourth alarm information is issued, and a filler dredging action of the adsorption module 11 is performed to eliminate the filler blockage of the adsorption module 11.

[0095] It can be understood that by collecting the outlet flue gas pollutant concentration of the adsorption tower 1 and comparing the outlet flue gas pollutant concentration with the concentration range, the outlet flue gas pollutant concentration of the adsorption tower 1 can be monitored, and the over-standard of pollutants in the outlet flue gas of the adsorption tower 1 can be avoided.

[0096] When the inlet flue gas temperature is in the first temperature range, it indicates that the inlet flue gas temperature of the adsorption tower 1 is in a normal state, when the packing temperature of the adsorption module 11 is lower than the second temperature range, and the outlet flue gas temperature of the adsorption module 11 is lower than the third temperature range, it indicates that the packing temperature and the outlet flue gas temperature of the adsorption module 11 are in an abnormally low state, and when the outlet flue gas pollutant concentration of the adsorption tower 1 is higher than the concentration range, it indicates that the outlet flue gas pollutant concentration of the adsorption tower 1 is in an abnormally high state. Therefore, by combining the inlet flue gas temperature of the adsorption tower 1, the packing temperature and the outlet flue gas temperature of the adsorption module 11, and the outlet flue gas pollutant concentration of the adsorption tower 1, it can be determined that the packing of the adsorption module 11 is blocked, causing the flue gas to flow poorly. Therefore, by issuing the fourth alarm information, the working personnel can be prompted to take precise cooperative actions in a timely manner, and by performing the packing unblocking action of the adsorption module 11, the packing blockage problem of the adsorption module 11 can be solved in a timely manner, thereby ensuring the smooth flow of flue gas. Therefore, the timely solution of the adsorption module 11 failure is ensured, and the stable and continuous operation of the adsorption tower 1 is ensured.

[0097] It should be noted that the collection method of the outlet flue gas pollutant concentration of the adsorption tower 1 can be set according to actual needs, and is not limited, for example, a plurality of pollutant concentration sensors are arranged at the outlet of the adsorption tower 1, and the plurality of pollutant concentration sensors can detect the concentrations of nitrogen oxides, sulfur dioxide, and smoke dust, etc.

[0098] The outlet flue gas pollutant concentration of the adsorption tower 1 needs to be within the concentration range, and the specific value of the concentration range can be set according to actual needs, and is not limited, for example, when the monitored pollutant is nitrogen oxides, the concentration range of nitrogen oxides is not more than 50 mg / Nm 3 , when the monitored pollutant is sulfur dioxide, the concentration range of sulfur dioxide is not more than 35 mg / Nm 3 , and when the monitored pollutant is smoke dust, the concentration range of smoke dust is not more than 5 mg / Nm 3 .

[0099] When all the outlet flue gas pollutant concentrations of the adsorption tower 1 exceed 1 mg / Nm 3 , the fourth alarm information of the first degree can be issued, and when the outlet flue gas pollutant concentration of the adsorption tower 1 exceeds the corresponding concentration range, the fourth alarm information of the second degree can be issued.

[0100] The fourth alarm information is used to prompt the working personnel, and the issuing method of the fourth alarm information can be set according to actual needs, and is not limited, for example, the fourth alarm information can be sound information, light information, sound and light information, etc., and the fourth alarm information can be issued by a sound alarm, a light alarm, a sound and light alarm, etc.

[0101] The specific type of the filling material unblocking action of the adsorption module 11 can be set according to actual needs, and is not limited, for example, the filling material unblocking of the adsorption module 11 can be completed by using the air cannon arranged on the adsorption module 11.

[0102] When the filling material unblocking action of the adsorption module 11 still cannot unblock the filling material, the operator can directly use the manual method to unblock.

[0103] In some embodiments, the adsorption tower monitoring method further comprises:

[0104] Collecting the first inlet flue gas pressure and the outlet flue gas pressure of each adsorption module 11;

[0105] Comparing the first inlet flue gas pressure with the pressure range and the outlet flue gas pressure with the pressure range;

[0106] When the first inlet flue gas pressure is higher than the pressure range and the outlet flue gas pressure is lower than the pressure range, a fifth alarm information is issued, and a filling material unblocking action of the adsorption module 11 is performed to eliminate the filling material blockage of the adsorption module 11.

[0107] It can be understood that by collecting the first inlet flue gas pressure and the outlet flue gas pressure of each adsorption module 11, and comparing the first inlet flue gas pressure with the pressure range and the outlet flue gas pressure with the pressure range, the monitoring of the inlet flue gas pressure and the outlet flue gas pressure of the adsorption module 11 in the adsorption tower 1 can be realized.

[0108] When the first inlet flue gas pressure is higher than the pressure range, it indicates that the inlet flue gas pressure of the adsorption module 11 is in an abnormally high state, and when the outlet flue gas pressure is lower than the pressure range, it indicates that the outlet flue gas pressure of the adsorption module 11 is in an abnormally low state. Therefore, by combining the first inlet flue gas pressure and the outlet flue gas pressure of the adsorption module 11, it can be determined that the filling material blockage problem occurs in the adsorption module 11, which causes the flue gas to flow poorly. Therefore, by issuing the fifth alarm information, the operator can be prompted to perform accurate cooperation processing action in time, and by performing the filling material unblocking action of the adsorption module 11, the filling material blockage problem in the adsorption module 11 can be eliminated in time, thereby ensuring the smooth flow of flue gas. Therefore, the timely solution of the adsorption module 11 failure is ensured, and the stable and continuous operation of the adsorption tower 1 is ensured.

[0109] It should be noted that the collection method of the first inlet flue gas pressure and the outlet flue gas pressure of the adsorption module 11 can be set according to actual needs, and the example is that at least one first pressure sensor is arranged at the inlet of the adsorption module 11 to collect the first inlet flue gas pressure of the adsorption module 11 by using the first pressure sensor, and at least one second pressure sensor is arranged at the outlet of the adsorption module 11 to collect the outlet flue gas pressure of the adsorption module 11 by using the second pressure sensor.

[0110] Both the first inlet flue gas pressure and the outlet flue gas pressure of the adsorption module 11 need to be within the pressure range, and the specific value of the pressure range can be set according to actual needs, and the example is that the pressure range can be 1.1-1.2 times of the standard atmospheric pressure.

[0111] The fifth alarm information is used to prompt the operating personnel, and the sending method of the fifth alarm information can be set according to actual needs, and the example is that the fifth alarm information can be sound information, light information, sound and light information, etc., and the sending of the fifth alarm information can be through a sound alarm, a light alarm, a sound and light alarm, etc.

[0112] Among them, according to the judgment of the inlet flue gas temperature and the outlet flue gas pollutant concentration of the adsorption tower 1 and the packing temperature and the outlet flue gas temperature of the adsorption module 11, the packing dredging action of the adsorption module 11 can be performed, and according to the judgment of the first inlet flue gas pressure and the outlet flue gas pressure of the adsorption module 11, the packing dredging action of the adsorption module 11 can also be performed, and at the same time, the execution of the packing dredging action can also be according to the combination of the two, and the limitation is not made.

[0113] In some embodiments, the adsorption tower monitoring method further comprises:

[0114] Collecting the second inlet flue gas pressure of the adsorption tower 1;

[0115] Comparing the second inlet flue gas pressure with the pressure range;

[0116] Among them, when the first inlet flue gas pressure is higher than the pressure range, and the second inlet flue gas pressure is higher than the pressure range, and the outlet flue gas pressure is lower than the pressure range, the fifth alarm information is sent, and the packing dredging action of the adsorption module 11 is performed.

[0117] It can be understood that by collecting the second inlet flue gas pressure of the adsorption tower 1, and comparing the second inlet flue gas pressure with the pressure range, the monitoring of the inlet flue gas pressure of the adsorption tower 1 can be realized, and at the same time, the packing dredging action of the adsorption module 11 is performed according to the combination of the first inlet flue gas pressure, the second inlet flue gas pressure and the outlet flue gas pressure, so that the overall solution to the failure of the adsorption module 11 is more accurate and efficient.

[0118] It should be noted that the collection method of the flue gas pressure at the second inlet of the adsorption tower 1 can be set according to actual needs, and the example is that at least one third pressure sensor is arranged at the inlet of the adsorption tower 1 to collect the flue gas pressure at the second inlet of the adsorption tower 1 by using the third pressure sensor.

[0119] As shown in Figure 3 The embodiment of the present disclosure also provides an adsorption tower monitoring system of a COAP system, which comprises a collection module 2, a comparison module 3 and an execution module 4. The collection module 2 is used to collect the inlet flue gas temperature of the adsorption tower 1 and the packing temperature and the outlet flue gas temperature of each adsorption module 11. The comparison module 3 is used to compare the inlet flue gas temperature with the first temperature range, the packing temperature with the second temperature range and the outlet flue gas temperature with the third temperature range. The execution module 4 is used to issue corresponding alarm information according to the comparison result and to perform corresponding defect elimination action.

[0120] It can be understood that the inlet flue gas temperature of the adsorption tower 1 can be monitored by collecting the inlet flue gas temperature of the adsorption tower 1 and comparing the inlet flue gas temperature with the first temperature range. The packing temperature of the adsorption module 11 in the adsorption tower 1 can be monitored by collecting the packing temperature of each adsorption module 11 and comparing the packing temperature with the second temperature range. The outlet flue gas temperature of the adsorption module 11 in the adsorption tower 1 can be monitored by collecting the outlet flue gas temperature of each adsorption module 11 and comparing the outlet flue gas temperature with the third temperature range. At the same time, the corresponding alarm information can be issued according to the comparison result of the inlet flue gas temperature with the first temperature range, the packing temperature with the second temperature range and the outlet flue gas temperature with the third temperature range, and the corresponding defect elimination action can be performed. Thus, the fault problem of the adsorption tower 1 can be solved in time, the continuous operation of the adsorption tower 1 can be ensured, the problem that the pollutant removal cannot meet the standard can be avoided, the operation efficiency of the adsorption tower 1 is improved, and the stable operation of the COAP system is ensured.

[0121] It should be noted that the above explanation of the embodiment of the adsorption tower monitoring method of the COAP system also applies to each module in the adsorption tower monitoring system of the COAP system of the embodiment, and will not be repeated here.

[0122] As shown in Figure 5As shown, in some embodiments, the adsorption module 11 includes a tower barrel 111, a distributor 112, a discharger 113, and a discharge hopper 114, the distributor 112 and the discharger 113 are sequentially arranged in the tower barrel 111 from top to bottom, an adsorption zone is formed between the distributor 112 and the discharger 113, the discharge hopper 114 is arranged below the discharger 113, above the distributor 112 for receiving the filler, the distributor 112 is used to uniformly arrange the filler in the adsorption zone, and the discharger 113 is used to uniformly discharge the filler at the bottom of the adsorption zone into the discharge hopper 114; wherein the collection module is used to collect the filler temperature in the adsorption zone and collect the outlet flue gas temperature of the adsorption zone.

[0123] It can be understood that the upper part of the distributor 112 receives the filler and forms a transition layer, the distributor 112 uniformly distributes the filler in the transition layer to the adsorption zone and sequentially stacks to form an adsorption layer, and the low-temperature flue gas enters the tower barrel 111 and contacts the adsorption layer in the adsorption zone, so that the flue gas is adsorbed and purified by the filler to become clean flue gas, and the clean flue gas is discharged from the tower barrel 111, thereby completing the adsorption of the flue gas.

[0124] Wherein, the adsorption saturated filler in the adsorption layer falls into the corresponding discharge hopper 114 through the discharger 113, and the filler discharged through the discharge hopper 114 can be sent to the subsequent regeneration equipment for regeneration, thereby realizing cyclic use.

[0125] Thus, the adsorption saturated filler at the bottom of the adsorption layer is discharged, and the new filler is arranged on the top of the adsorption layer through the distributor 112, so that the adsorption layer maintains a certain adsorption capacity, and the filler in the adsorption layer gradually loses the ability of adsorption and purification as the adsorption time is prolonged.

[0126] It should be noted that the adsorption tower 1 provided in the embodiment has a plurality of stacked adsorption modules 11, and an adsorption layer can be arranged in each adsorption module 11, so that each adsorption module 11 can independently perform a flue gas treatment process, thereby greatly improving the flue gas treatment amount of the adsorption tower 1 per unit time.

[0127] The stacking mode of the plurality of adsorption modules 11 can be set according to actual needs, and no limitation is made thereto. For example, the plurality of adsorption modules 11 are stacked in alignment with each other in the vertical direction, specifically, the top ends and the bottom ends of the tower barrels 111 of the plurality of adsorption modules 11 are sequentially abutted and connected, thereby forming a tower body which can be considered as an integrated structure in appearance, so as to stabilize the structure of the adsorption tower 1. The outer wall of the adsorption tower 1 can be provided with a plurality of inlets and a plurality of outlets corresponding to the plurality of adsorption modules 11.

[0128] Wherein, the tower barrel 111 of the adsorption module 11 can be divided into a plurality of tower barrel 111 segments, and the tower barrel 111 segments are spliced to form the tower barrel 111, thereby reducing the requirements for hoisting and transportation.

[0129] For example,Figure 5 As shown, in some embodiments, the distributor 112 includes a plurality of distributing cones 1121 arranged in parallel. The lower end of the distributing cones 1121 is provided with a distributing pipe 1122. Adjacent distributing cones 1121 are sealed together to prevent flue gas from passing upward through the distributor 112 and entering the transition layer. The flue gas outlet of the adsorption zone is arranged in the horizontal direction opposite to the lower end of the distributing cones 1121 and / or the distributing pipe 1122, so that the clean flue gas discharged from the top of the adsorption layer can be discharged from the flue gas outlet of the adsorption zone.

[0130] The upper dimension of the feeding cone 1121 is larger than its lower dimension, and its cross-sectional area gradually decreases downward in the vertical direction. After the adjacent feeding cones 1121 are sealed together, there is a certain gap between the lower ends of the adjacent feeding cones 1121. At the same time, the feeding pipe 1122 is connected to the lower outlet of the feeding cone 1121 in a matching manner, and there is also a certain gap between the adjacent feeding pipes 1122. The packing material in the transition layer passes downward through the feeding cones 1121 and the feeding pipes 1122 at the lower end of the feeding cones 1121 and enters the adsorption zone to form an adsorption layer. The top surface of the adsorption layer is flush with the bottom end of the feeding pipe 1122. Therefore, the gap space between the lower ends of the adjacent feeding cones 1121 and the gap space between the adjacent feeding pipes 1122 are located above the adsorption layer. This space is opposite to and connected to the flue gas outlet of the adsorption zone in the horizontal direction. Clean flue gas is discharged from the top of the adsorption layer and enters the space above the adsorption layer, and then is discharged from the flue gas outlet of the adsorption zone.

[0131] It should be noted that the width of the flue gas outlet in the adsorption zone can be the same as the width of the distributor 112, so that the clean flue gas can be discharged more smoothly from the tower 111 and the resistance at the flue gas outlet in the adsorption zone can be reduced.

[0132] like Figure 5 As shown, in some embodiments, the feeder 113 includes a plurality of feed cones 1131 arranged side by side and spaced apart. A feed pipe 1132 is provided at the lower end of each feed cone 1131. The flue gas inlet of the adsorption zone is horizontally positioned opposite the feed cones 1131 and / or the feed pipes 1132. The feed cones 1131 are spaced apart to allow low-temperature flue gas to pass upward through the feeder 113 and enter the adsorption layer. That is, the feed cones 1131 and the feed pipes 1132 connected to their lower ends are spaced apart, and the low-temperature flue gas enters from the flue gas inlet of the adsorption zone and disperses upward through the gaps between the feed cones 1131 to enter the adsorption layer.

[0133] The width of the flue gas inlet in the adsorption zone can be the same as the width of the feeder 113, thereby reducing the inlet resistance of the low-temperature flue gas and promoting the dispersed entry of the low-temperature flue gas into the tower 111, so as to make uniform contact with the packing between the adsorption layers.

[0134] The fillers at the bottom of the adsorption layer are directly dropped through the dropping tapers 1131 and the dropping pipes 1132 below the dropping tapers 1131. It should be noted that, in order to avoid the fillers in the adsorption layer from falling through the gaps between the dropping tapers 1131, the size of the gaps between the dropping tapers 1131 should be smaller than the size of the filler particles.

[0135] As shown in Figure 5 some embodiments, the dropping device 113 further comprises a plurality of discharge hoppers 1133 arranged side by side, the adjacent discharge hoppers 1133 are sealingly connected, the discharge hoppers 1133 are located above the dropping tapers 1131, and the lower end of at least one discharge hopper 1133 is oppositely arranged with the upper end of the dropping taper 1131. The fillers at the bottom of the adsorption layer first pass through the discharge hoppers 1133, and then fall into the corresponding dropping tapers 1131 from the discharge hoppers 1133. After the low-temperature flue gas passes through the gaps between the dropping tapers 1131, it enters the adsorption layer from the discharge hoppers 1133 upwards.

[0136] In some embodiments, the upper end of one dropping taper 1131 can be opposite to the lower end of four discharge hoppers 1133, and the lower end of the discharge hopper 1133 is generally flush with the upper end of the dropping taper 1131 in the horizontal direction.

[0137] As shown in Figure 5 and Figure 6 some embodiments, the adsorption module further comprises a discharging device 115, the discharging device 115 comprises a tray 1151, a dropping rake 1152 and a driving assembly 1153. The tray 1151 is arranged below the dropping device 113 and is spaced from the dropping port. The tray 1151 is used to receive the dropping of the dropping device 113. The dropping rake 1152 is arranged between the tray 1151 and the dropping device 113 and is slidingly arranged on the tray 1151 in a predetermined direction. The driving assembly 1153 is arranged on the tower drum 111, and the driving assembly 1153 is drivingly connected with the dropping rake 1152. The driving assembly 1153 is used to drive the dropping rake 1152 to reciprocally move in the predetermined direction and adjust the moving frequency of the dropping rake 1152, so as to rake the fillers on the tray 1151 into the discharging hopper 114 at a predetermined rate.

[0138] In some embodiments, the driving assembly 1153 drives the dropping rake 1152 to reciprocally move in the predetermined direction and adjusts the moving frequency of the dropping rake 1152, so as to stir the fillers on the tray 1151 with the dropping rake 1152, thereby adjusting the rate of the fillers falling from the tray 1151 to the discharging hopper 114.

[0139] In some embodiments, the specific type of the driving assembly 1153 can be set according to actual needs, and no limitation is made thereto. For example, the driving assembly 1153 can be a hydraulic cylinder.
