Description

Technical Field

[0001] The present invention relates to the field of intelligent application technology, and in particular to a quicklime digestion system, method, device and electronic equipment. Background Art

[0002] A quicklime digester is a device used to mix quicklime raw materials with water to produce slaked lime products. The component in the quicklime raw materials that reacts with water is mainly calcium oxide. Therefore, in the quicklime digestion process, the amount of water used is closely related to the content of calcium oxide in the quicklime raw materials. The method of converting quicklime into slaked lime products in the prior art is usually: for the same batch of quicklime raw materials, a chemical test is performed to detect the content of calcium oxide in the batch of quicklime raw materials; the content of calcium oxide in the batch of quicklime raw materials is obtained, and the amount of water to be added is determined according to the content of calcium oxide; the batch of quicklime raw materials is introduced into the quicklime digester through a conveyor belt, and water is injected into the quicklime digester according to the determined amount of water to be added, so that the quicklime and water are mixed to produce slaked lime products.

[0003] However, the inventors found that the quicklime raw materials of the same batch but imported at different time periods have certain differences in average purity, the amount of introduction caused by particle size, etc., so the content of calcium oxide also has certain differences, so the amount of water required should also be different. However, in the prior art, the amount of water added is determined, so the amount of water injected in each time period is fixed, which leads to differences in the quality of the slaked lime products generated at different time periods. In some time periods, due to the high content of calcium oxide in the quicklime raw material, the amount of water injected is insufficient, resulting in the incomplete chemical reaction and the mixed unreacted quicklime raw material in the slaked lime product; in some time periods, due to the low content of calcium oxide in the quicklime raw material, the amount of water injected is too much, resulting in a high water content in the generated slaked lime product, high product viscosity, and the risk of equipment blockage. In other words, there is a problem in the prior art that the amount of water injected cannot be automatically adjusted according to the calcium oxide content of the quicklime raw material in the quicklime digester in real time.

[0023] In a specific embodiment, three temperature sensors are evenly distributed in the first chamber, the second chamber, and the third chamber respectively; The control module is also specifically used for: Real-time monitoring of temperature value changes of each temperature sensor in the first chamber, the second chamber and the third chamber; When the temperature values ​​of the temperature sensors in the first chamber, the second chamber and the third chamber reach a stable state, it is determined whether the temperature value of the rightmost temperature sensor in the third chamber is within the target temperature range, or whether the moisture content fed back by the moisture detector is less than the target moisture content; When the temperature value fed back by the temperature sensor on the far right of the third chamber is greater than the upper threshold of the target temperature range, it is determined that the water injection amount needs to be increased, and the target water injection amount is increased and adjusted according to the preset adjustment granularity to obtain a new target water injection amount; When the temperature value fed back by the temperature sensor on the far right of the third chamber is less than the lower limit threshold of the target temperature range, or the moisture content fed back by the moisture detector is not less than the target moisture content, it is determined that the water injection amount needs to be reduced, and the target water injection amount is reduced and adjusted according to the preset adjustment granularity to obtain a new target water injection amount; The new target water injection volume is fed back to the variable water pump, and the step of real-time monitoring of the temperature value changes of each temperature sensor in the first chamber, the second chamber and the third chamber is continued.

[0024] The digestion reaction in the present invention refers to the digestion reaction of quicklime, which generally refers to the process in which calcium oxide (CaO) in quicklime reacts chemically with water (H2O) to generate calcium hydroxide (Ca(OH)2). The chemical equation is: CaO + H2O = Ca(OH)2. The digestion reaction of quicklime is an exothermic reaction that releases a large amount of heat. In practical applications, the digestion of quicklime is often used in the preparation of building materials, for example, lime slurry, lime paste, etc.

[0025] Since the weighing screw conveyor has the advantage of high measuring accuracy, in practical applications, in order to accurately measure the mass of quicklime raw materials, a weighing screw conveyor can be used as a conveyor in the quicklime digestion system.

[0026] Similarly, since the variable frequency motor driven screw pump has the advantage of being able to accurately control the amount of water added, in actual applications, in order to accurately control the amount of water added, a variable frequency motor driven screw pump can be used as a variable water pump in the quicklime digestion system.

[0027] In practical applications, nine temperature sensors can be arranged in the quicklime digester to measure the temperature at nine different locations, wherein three temperature sensors are evenly distributed in the first chamber, the second chamber, and the third chamber. Usually, the digester outlet is located at the lower right corner of the quicklime digester, and the temperature sensor on the far right of the third chamber is close to the digester outlet. The temperature of this temperature sensor is usually regarded as the temperature of the generated product. Usually, one or more moisture detectors are set at the outlet of the digester, that is, the outlet of the generated product, to detect the moisture content of the product. This allows the control module to determine whether the water injection volume needs to be adjusted based on the temperature and moisture content of the product. For example, whether the product is qualified is determined based on the measurement values ​​of the temperature sensor and moisture detector at the outlet of the digester, and the target temperature and moisture content of the product; if qualified, there is no need to adjust the water injection amount; if unqualified, determine whether to increase or decrease the water injection amount based on the measurement values ​​of the temperature sensor and moisture detector at the outlet of the digester, and gradually adjust the water injection amount according to the preset adjustment granularity (which can also be understood as the step size). During the adjustment process, it is necessary to monitor the temperature value changes of each temperature sensor in real time to determine whether the stable reaction stage has been reached. After reaching the stable reaction stage, determine again whether the temperature and moisture content of the product are qualified. If qualified, stop adjusting and inject water according to the current water injection amount; if unqualified, continue to adjust the water injection amount according to the preset adjustment granularity until the temperature and moisture content of the product are qualified.

[0028] In the quicklime digestion system provided in the embodiment of the present invention, since the quicklime digester is divided into three layers, each layer is a chamber, and the digester inlet is used as the feed port of the first chamber, the discharge port of the first chamber is located at the right end of the first chamber, and is used as the feed port of the second chamber; the discharge port of the second chamber is located at the left end of the second chamber, and is used as the feed port of the third chamber; the discharge port of the third chamber is the digester outlet, so, in the quicklime digestion system provided in the embodiment of the present invention, the quicklime moves in a zigzag shape from left to right in the digester. In the present invention, the time taken for the quicklime to move throughout the entire process in the digester is approximately 10 minutes, and the average time taken for each layer to move is approximately 2 to 3 minutes.

[0029] In summary, the system provided by the embodiment of the present invention can determine whether to adjust the water injection amount according to the measured values ​​of the temperature sensor and the moisture detector at the outlet of the digester, and during the adjustment process, the temperature value changes of each temperature sensor in the quicklime digester, and the temperature and moisture content of the product are combined to determine when the water injection amount adjustment is completed, thereby realizing automatic adjustment of the water injection amount, solving the problem in the prior art that the water injection amount cannot be automatically adjusted according to the calcium oxide content of the quicklime raw material in the quicklime digester in real time. It also avoids the problem of equipment blockage caused by high moisture content in the generated product.

[0030] The embodiment of the present invention also provides a quicklime digestion method, which is applied to the control module in the quicklime digestion system. Figure 2 , the method comprises the following steps: S201: Obtaining the weight value of the quicklime raw material fed back by the weighing sensor on the conveyor; S202: Determine the target water injection amount according to the weight value of the quicklime raw material; Specifically, the target water injection amount may be determined based on the weight value of the quicklime raw material and the preset ratio between the weight value of the quicklime raw material and the water injection amount.

[0031] According to empirical values, the amount of water required for each ton of quicklime raw material is about 350 to 400 liters. Therefore, in a specific embodiment, the ratio between the weight value of the quicklime raw material and the water injection amount can be preset to be: 1:350. In this way, if the weight value of the quicklime raw material is 10 tons, then the target water injection amount can be determined to be 3500 liters.

[0032] S203: Feeding back the target water injection volume to the variable water pump, so that the variable water pump injects water into the quicklime slaker according to the target water injection volume; When the variable water pump is injecting water into the quicklime slaker, it will also feed back the amount of water injected to the control module in real time, so that the control module can determine whether the amount of water injected has reached the target injection amount.

[0033] S204: Acquire the temperature values ​​fed back by the temperature sensors in the first chamber, the second chamber, and the third chamber, and the moisture content fed back by the moisture detector; S205: judging whether the water injection amount needs to be adjusted according to the temperature value fed back by the temperature sensor and the water content fed back by the moisture detector; if the water injection amount needs to be adjusted, executing step S206; Specifically, the step of judging whether the water injection amount needs to be adjusted according to the temperature value fed back by the temperature sensor and the water content fed back by the moisture detector may include: Real-time monitoring of temperature value changes of each temperature sensor in the first chamber, the second chamber and the third chamber; When the temperature values ​​of the temperature sensors in the first chamber, the second chamber and the third chamber reach a stable state, it is determined whether the temperature value of the rightmost temperature sensor in the third chamber is within the target temperature range, or whether the moisture content fed back by the moisture detector is less than the target moisture content; wherein, the step of determining whether the temperature value of each temperature sensor has reached a stable state is, for each temperature sensor, comparing the temperature value of the temperature sensor with the previous temperature value to determine whether the difference between them is less than a preset fluctuation range; if so, it is confirmed that the temperature value of the temperature sensor has reached a stable state.

[0034] When the temperature value fed back by the temperature sensor on the far right of the third chamber is greater than the upper threshold of the target temperature range, it is determined that the water injection amount needs to be increased; When the temperature value fed back by the rightmost temperature sensor of the third chamber is less than the lower limit threshold of the target temperature range, or the moisture content fed back by the moisture detector is not less than the target moisture content, it is determined that the water injection amount needs to be reduced.

[0035] In the quicklime digestion reaction, at the beginning of the reaction, the temperature of the first chamber is the highest, and the temperature of the third chamber is the lowest. In the process of reaching a stable reaction, the temperature of each temperature sensor in the first chamber gradually increases from left to right, and the temperature of each temperature sensor in the second chamber gradually decreases from right to left. Among them, the temperature of the rightmost temperature sensor in the second chamber is the highest, and the temperature of each temperature sensor in the third chamber gradually decreases from left to right.

[0036] In the present invention, the time taken for quicklime to move throughout the entire process in the slurry is approximately 10 minutes, and the average time taken for each layer to move is approximately 2 to 3 minutes. In this way, after each adjustment of the water injection volume, the quicklime in the first chamber reacts with the adjusted water volume; and the quicklime before adjustment has reached the second chamber, and the temperature of each temperature sensor in the current second chamber is recorded (the quicklime before adjustment). After 2 minutes, the quicklime in the first chamber reaches the second chamber, and the quicklime in the second chamber reaches the third chamber (the quicklime before adjustment). At this time, the temperature of each temperature sensor in the current second chamber (the quicklime after adjustment) can be compared with the temperature of each temperature sensor in the original second chamber (the quicklime before adjustment) and the standard temperature to determine whether the temperature of each temperature sensor in the current second chamber is closer to the standard temperature than the temperature of each temperature sensor in the original second chamber (the quicklime before adjustment). If so, it can be determined that this adjustment operation is correct; and continue to observe for about 10 minutes. When the temperature of each temperature sensor of the quicklime in the digester reaches a stable state, determine whether the temperature and moisture content of the product are qualified. If qualified, end the adjustment of the water injection volume; if qualified, continue to adjust the water injection volume. Among them, the standard value is an empirical value set based on the temperature of each temperature sensor observed when the product is qualified in previous practice. Each temperature sensor corresponds to a standard value.

[0037] S206: Adjust the target water injection volume according to the preset adjustment granularity to obtain a new target water injection volume, and feed the new target water injection volume back to the variable water pump, so that the variable water pump injects water into the quicklime slaker according to the new target water injection volume, and return to step S204 to continue execution.

[0038] Specifically, the step of adjusting the target water injection volume according to the preset adjustment granularity to obtain a new target water injection volume may include: When the water injection volume needs to be increased, the target water injection volume is increased and adjusted according to the preset adjustment granularity to obtain a new target water injection volume; When the water injection volume needs to be reduced, the target water injection volume is reduced and adjusted according to the preset adjustment granularity to obtain a new target water injection volume.

[0039] The adjustment granularity can be set based on the minimum water output of the variable water pump and the empirical value. In practical applications, the setting range of the adjustment granularity can be 1 to 3 liters of water. For example, if the adjustment granularity is set to 1, then the water injection volume increases or decreases by 1 liter each time it is adjusted.

[0040] The following is a practical example to further illustrate in detail the method of the control module applied to the quicklime digestion system provided by the embodiment of the present invention.

[0041] In this embodiment, the conveyor adopts a weighing screw conveyor, and the variable water pump adopts a variable frequency motor driven screw pump. Nine temperature sensors are arranged in the quicklime digester, among which three temperature sensors are evenly distributed in the first chamber, the second chamber and the third chamber respectively. The conveyor conveys 10 tons of quicklime raw materials per hour, and the ratio between the weight value of the quicklime raw materials and the water injection volume is: 1:350. The target temperature range of the product is [100,120] degrees, and the target moisture content of the product is: moisture content <2%, and the particle size is adjusted to 1 liter of water.
