Step 2: Execute the deacidification processing module. In this step, the drive motor 8 drives the book clamping device 7 to perform the deacidification treatment of books. After the deacidification treatment of the books is completed, step 4 is executed.

Step 3: Start the emergency incident handling module:

The working process of the emergency accident module is as follows. First, close the cover of the deacidification tank 2 and close all the valves in the equipment. Next, open the first one-way air valve 81 and the second one-way air valve 82, and turn on the air pump 10; after the air pump 10 runs for 5 minutes, the first air pressure sensor 71 located in the liquid storage tank 1 starts to detect the liquid storage tank 1. In the air pressure, judge whether the air pressure value is between 0.05 and 0.15 MPa, and the value fluctuation range is less than 2 kPa, and can be stably maintained for more than 10 minutes in this state: a) If the liquid storage tank 1 cannot meet the above air pressure value requirements, then The system opens the eleventh valve 31 and the twelfth valve 32, and then the smart console prompts "equipment failure" on the display to wait for manual maintenance, and the alarm also alerts; b) If the liquid storage tank 1 meets the above-mentioned pressure value requirements , The second air pressure sensor 74 located in the deacidification treatment tank 2 starts to detect the air pressure in the deacidification treatment tank 2; judge whether the air pressure value is lower than 16kPa and can be maintained for more than 10 minutes: i) If yes, the system will shut down first All valves are then automatically shut down; ii) If not, the system opens the eleventh valve 31 and the twelfth valve 32, and then the smart console prompts "equipment failure" through the display and waits for manual maintenance, and the alarm also alerts .

Step 4. Start the running detection module. In this module, first, the second air pressure sensor 74 in the deacidification treatment tank 2 starts to detect the air pressure in the deacidification treatment tank 2, and determines whether the measured air pressure value is between 0.05 and 0.15 MPa, and the value fluctuation range is less than 2kPa, and can be stably maintained for more than 10 minutes in this state:

a) If the air pressure value in the deacidification treatment tank 2 does not meet the conditions, perform step 5;

b) If the air pressure value in the deacidification treatment tank 2 satisfies the conditions, the first air pressure sensor 71 in the liquid storage tank 1 starts to detect the air pressure in the liquid storage tank 1 and judges whether the measured pressure value is between 0.05 and 0.15 MPa If the value fluctuation range is less than 2kPa, and can be kept stable for more than 10 minutes in this state: i) If the air pressure value in the liquid storage tank 1 does not meet the conditions, perform step 5;

ii) If the air pressure value in the liquid storage tank 1 meets the conditions, finally judge whether the book deacidification process has been running for 1h; ①If the above process has lasted for 1h, then execute step 6 to end the running module; ②If the above process has not lasted for 1h , Jump to the beginning of this step to continue execution.

Step 5: Execute the accident handling module. In the accident handling module, first start the liquid circulation module; then start the liquid return module, run for 10 minutes, and then judge the detection by the second buoy liquid level sensor 75 in the deacidification treatment tank 2 The liquid level of the deacidified liquid: a) If the detected liquid level is at "low level", execute step 3 emergency accident module; b) if the liquid level is not "low level", then jump to the liquid in this step The reflow module continues to execute.

Step 6. Execute the end operation module, and the system enters the end operation module", first execute the liquid circulation module, then start the liquid return module, and then judge whether the liquid level detected by the second buoy liquid level sensor 75 in the deacidification treatment tank 2 At the "low level": a) If the level is not at the "low level", skip to the "liquid reflux module" in this step and continue to reflux until the deacidification treatment tank 2 is at the "low level"; b) If the liquid level is at the "low liquid level", the system first closes all valves; then opens the second one-way valve 82, starts the suction pump 10, and after the suction pump 10 runs for 10 minutes, the second air pressure sensor in the deacidification treatment tank 2 74 Start to detect the air pressure in the deacidification treatment tank 2 to determine whether the air pressure value is lower than 16kPa and can be maintained for more than 10 minutes:

i) If not, then the system opens the first valve (21) and the twelfth valve 32, and then the smart console prompts "equipment failure" through the display to wait for manual maintenance, and the alarm also alerts.

ii) If yes, the system closes the second one-way valve 82 and then opens the twelfth valve 32. After running for 10 minutes, the second air pressure sensor 74 in the deacidification treatment tank 2 starts to detect the air pressure in the deacidification treatment tank 2 , Determine whether the air pressure value is between 0.05 and 0.15 MPa, and the value fluctuation range is less than 2 kPa, and can be kept stable for more than 10 minutes in this state: ① If not, then the system opens the first valve (21) and the twelfth valve 32. Then the smart console prompts "equipment failure" on the display and waits for manual maintenance, and the alarm also alerts.

②If it is, the system opens the deacidification treatment tank 2, and then starts the eleventh valve 31. After waiting for 20 minutes of operation, the system closes all valves, and then the system automatically shuts down.

Further, the specific workflow of step 1 "pre-check module" is as follows: check whether all valves in the system equipment are in a closed state: c) if not, the system will close all valves; d) if yes, then liquid storage tank 1 The first buoy liquid level sensor 72 in the first buoy starts to detect the liquid level in the liquid storage tank 1, and determines whether the detected liquid level is not lower than the "low liquid level": i) If it is lower than the "low liquid level", the system Open the thirteenth valve 33, and then replenish the deacidified liquid to the liquid storage tank 1 through the liquid supplement pipe 99 until the liquid level is not lower than the "low liquid level"; ii) If it is not lower than the "low liquid level", then the liquid is stored The concentration sensor 73 in the tank 1 starts to detect the concentration in the liquid storage tank 1, and determines whether the sensor 73 detects that the concentration is not less than 1.5g/L: ①If it is less than 1.5g/L, then the automatic feeder 9 is turned on, and Add alkaline particles to the deacidified liquid in the storage tank 1 until the concentration is not less than 1.5g/L; ②If the concentration is not less than 1.5g/L, the first air pressure sensor in the storage tank 1 71. Start to detect the air pressure in the liquid storage tank 1, and determine whether the detected air pressure value is between 0.05 and 0.15 MPa, and the value fluctuation range is less than 2 kPa, and can be stably maintained for more than 10 minutes in this state:

α) If yes, the system enters the "deacidification module";

β) If the above air pressure value requirements cannot be achieved, the system enters the "emergency accident module".

Further, the specific work flow of the second deacidification treatment module is as follows: First, the system detects the height of the book through the first height sensor 76 and the second height sensor 77 to confirm whether the deacidification treatment tank 2 has been placed in the waiting process Books: a) If neither the first height sensor 76 nor the second height sensor 77 detects a book, the smart console will prompt "No book is inserted" through the display and the alarm will also give an alarm reminder;

b) If the first height sensor 76 detects a book, but the second height sensor 77 does not detect a book, the required deacidification liquid level in the deacidification treatment tank 2 is the "medium level"; if the first height The sensor 76 and the second height sensor 77 both detect the book, and the required liquid level of the deacidification liquid in the deacidification treatment tank 2 is the "high level";

Then, the system closes the deacidification treatment tank 2, and then starts the "liquid transmission module". After the "liquid transmission module" runs for 5 minutes, it determines the deacidification detected by the second buoy liquid level sensor 75 in the deacidification treatment tank 2. Whether the liquid level in the treatment tank 2 reaches the required liquid level: i) If it does not reach the required height, continue to execute the "liquid transfer module" until the required height is reached;

ii) If the liquid level of the required height is reached, the liquid circulation module is started, and then the driving motor 8 is started to make the book holding device 7 rotate and pull back and forth, and the running detection module is started synchronously.

Further, the working process of the liquid transfer module is as follows: the system first opens the first valve (21), then opens the second valve (22), then opens the first delivery device 3, and then opens the third valve (27).

Further, the working process of the liquid circulation module is as follows: the system first closes the second valve 22, then closes the third valve 27, and then sequentially opens the fourth valve 24, the second conveying device 4, the eighth valve 28, and the ninth valve 29, The fifth valve 25 and the tenth valve 30.

Further, the working process of the liquid return module is as follows: the system first closes the fourth valve 24, the eighth valve 28, the ninth valve 29, the fifth valve 25, and the tenth valve 30 in sequence, closes the second conveying device 4, and then opens in sequence The seventh valve 23, the first conveying device 3, and the sixth valve 26.

Further, the "low liquid level" means that the liquid level is about 5 mm higher than the bottom of the tank.

Further, the "high liquid level" is about 10 cm away from the top of the deacidification tank

Further, the "medium liquid level" means that the liquid level is about 60 cm higher than the bottom of the tank.

After the smart console is turned on, the condensate collector 11 is started, and after the 5min warm-up time is over, after the equipment starts normally, the specific work flow of deacidification treatment is as follows, as shown in Figure 1 to Figure 10:

Step 1. First start the pre-check module to detect all the valves in the system equipment, the liquid level in the liquid storage tank 1, the concentration of the deacidification liquid in the deacidification treatment tank 2, and the air pressure in the liquid storage tank 1, a) If the detection result is normal, go to step 2; b) If the detection result is abnormal, go to step 3.

Specifically, the working process of the pre-check module is as follows: check whether all valves in the system equipment are in a closed state: c) If not, the system will close all valves;

d) If yes, the first buoy liquid level sensor 72 in the liquid storage tank 1 starts to detect the liquid level in the liquid storage tank 1, and determines whether the detected liquid level is not lower than the "low liquid level" (low liquid level) It means that the liquid level is about 5mm higher than the bottom of the tank): i) If it is lower than the "low liquid level", the system opens the thirteenth valve 33, and then through the replenishment pipeline 99, the liquid storage tank 1 is refilled with deacidified liquid until the liquid Level is not lower than the "low level"; ii) if it is not lower than the "low level", the concentration sensor 73 in the liquid storage tank 1 starts to detect the concentration in the liquid storage tank 1, and determines whether the sensor 73 detects the concentration Not less than 1.5g/L: ①If it is less than 1.5g/L, the automatic feeder 9 is turned on, and the alkaline substance particles are added to the deacidified liquid in the storage tank 1 until the concentration is not less than 1.5g/L L; ②If the concentration is not less than 1.5g/L, the first air pressure sensor 71 located in the liquid storage tank 1 starts to detect the air pressure in the liquid storage tank 1, and judges whether the detected air pressure value is between 0.05 and 0.15 MPa And the value fluctuation range is less than 2kPa, and it can be kept stable for more than 10min in this state:

α) If yes, the system enters the deacidification module;

β) If the above air pressure value requirements cannot be achieved, the system enters the emergency accident module.

Step 2: Execute the deacidification processing module. In this step, the drive motor 8 drives the book clamping device 7 to perform the deacidification processing of the books. After the book deacidification processing is completed, execute step 4 to start the running detection module.

Specifically, the work flow of the deacidification treatment module is as follows: First, the system detects the height of the book through the first height sensor 76 and the second height sensor 77 to confirm whether the book to be processed has been placed in the deacidification treatment tank 2 : A) If neither the first height sensor 76 nor the second height sensor 77 detects a book, the smart console will prompt "No book is inserted" through the display and the alarm will also give an alarm reminder;

b) If the first height sensor 76 detects a book, but the second height sensor 77 does not detect a book, the required deacidification liquid level in the deacidification treatment tank 2 is "medium level" (medium level refers to The liquid level is about 60cm higher than the bottom of the tank); if both the first height sensor 76 and the second height sensor 77 detect books, the required liquid level of the deacidification liquid in the deacidification treatment tank 2 is "high level" ( Refers to the liquid level is 10cm from the top of the deacidification tank).

ii) If the liquid level of the required height is reached, start the "liquid circulation module", then start the drive motor 8 to make the book holding device 7 rotate and pull back and forth, and start the "run detection module" synchronously.

Step 3: Start the emergency incident handling module.

Step 4. Start the running detection module. In this module, first, the second air pressure sensor 74 in the deacidification treatment tank 2 starts to detect the air pressure in the deacidification treatment tank 2, and determines whether the measured air pressure value is between 0.05 and 0.15 MPa, and the value fluctuation range is less than 2kPa, and can be kept stable for more than 10min in this state:

a) If the air pressure value in the deacidification treatment tank 2 does not meet the conditions, perform step 5 (accident handling module);

b) If the air pressure value in the deacidification treatment tank 2 satisfies the conditions, the first air pressure sensor 71 in the liquid storage tank 1 starts to detect the air pressure in the liquid storage tank 1 and judges whether the measured pressure value is between 0.05 and 0.15 MPa The value fluctuation range is less than 2kPa, and can be kept stable for more than 10min in this state: i) If the air pressure value in the liquid storage tank 1 does not meet the conditions, perform step 5 (accident handling module);
