Abstract
Description
Technical Field
[0001] This application relates to the field of chemical engineering technology, and particularly to a continuous automatic detection device and an ammonium salt synthesis system. Background Art
[0002] In the field of industrial production technology, the monitoring of parameters during the reaction process, such as temperature, pressure, pH, etc., is often involved. Different detection or monitoring devices are required for different monitoring items. The use of the detection device is also related to the state of the reactants and the changes during the reaction process. For example: in some reactions, the state of the reactants is a solid-liquid two-phase state. When detecting pH (acidity and alkalinity) or other parameters in this state, some solids will adhere to the detection device. If this part of the adhered material is not cleaned, it will affect the next detection. However, the existing detection devices all require manual removal of the detection device from the environment to be detected after the first detection, separate cleaning, and then putting it back into the detection environment for the next detection. For a reaction environment that needs to be sealed, multiple plugging and unplugging of the detection device will affect the sealing performance of the reaction device, bringing adverse effects to the reaction. Moreover, this detection method has low efficiency and high risk. Therefore, when detecting parameters in a closed intermittent reaction device, how to automatically clean the detector and make the cleaning liquid circulate in the system is the key to improving the detection quality and practicality of the reaction environment parameters of the closed intermittent reaction device.

Additionally, the phrase "in one embodiment" or "in an embodiment" that appears throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in one or more embodiments in any suitable manner.
[0020] It should also be noted that in this article, relative terms such as first and second are only used to distinguish one entity from another entity, and do not necessarily require or imply any actual relationship or order between these entities. Moreover, the terms "comprising", "including", or any other variant thereof are intended to cover non-exclusive inclusion, such that an article or terminal device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such an article or terminal device.

[0021] In the prior art, when detecting the parameters of the material to be detected, in order not to affect the results of the next detection, common detection devices all require manual removal of the detection device from the detection environment after the first detection, separate cleaning, and then putting it back into the detection environment for the next detection. For a reaction environment that needs to be sealed, multiple insertions and removals of the detection device will affect the sealing performance of the reaction device, bringing adverse effects to the reaction. Moreover, this detection method has low efficiency and high risk. Therefore, how to achieve automatic cleaning of the detector and make the cleaning liquid circulate in the system is the key to improving the detection quality and practicality of the reaction environment parameters of a closed intermittent reaction device.
[0022] In the present utility model, as Figures 1 to 3 shown, a continuous automatic detection device and an ammonium salt synthesis system are respectively provided.
[0023] In the first aspect, the utility model provides a continuous automatic detection device, including a sampling component, a detection component, and a cleaning component. The sampling component includes a sampler, a first tube valve, and a diaphragm pump. The sampling end of the sampler penetrates into the reactor and contacts the material to be detected. The other end of the sampler is connected to the first tube valve, and the other end of the first tube valve is connected to the diaphragm pump through a sampling pipeline. The other end of the diaphragm pump is connected to the detector of the detection component; wherein, the detection component also includes a central controller and a display, the display is electrically connected to the central controller, the central controller controls the first tube valve to extract the material to be detected, and the display displays the detection parameters of the real-time sampling; after the detector completes the detection, it is connected to the reactor through a softened water pipeline; the cleaning component is arranged in the softened water pipeline, including a dropper, and the cleaning liquid dripped by the dropper is connected to the reactor through a softened water pipeline.
[0024] like Figure 1 and Figure 3 As shown, in the continuous automatic detection device provided by the present invention, a closed-loop system is formed between the sampling component, the detection component and the cleaning component and the reactor. The sampling component automatically takes out the material to be detected in the reactor and transports it to the detector for detection, and the material after detection is returned to the reactor. In order to avoid the solid-liquid two-phase material to be detected from adhering to the detection mechanism of the detector and affecting the subsequent detection results, a cleaning component is provided. The cleaning component cleans the attachments at the detector end by dripping cleaning liquid into an independent softened water pipe, and returns to the reactor again through the pipeline circulation. This automatic detection device can not only detect the monitoring parameters of the material to be detected multiple times continuously, but also has a high accuracy of multiple detections. At the same time, the cyclic monitoring system keeps the sealing of the reactor from being destroyed, thereby improving the quality of the closed intermittent reaction device in detecting the reaction environment parameters and the practicality of the detection.
[0025] The "sealed intermittent reaction device" mentioned above refers to a chemical reaction device for intermittent reaction, and the reaction needs to be carried out in a sealed or closed environment.
[0026] It should be noted that the detection sensor of the aforementioned detector can be any one or more of a pH meter, a temperature sensor, a pressure sensor, a liquid level sensor, and a damping sensor. In actual use, the appropriate detection sensor type can be adaptively selected according to needs, and this embodiment does not make specific limitations on this.
[0027] In some embodiments, the aforementioned continuous automatic detection device further includes a dehydration component, which is connected to the bottom of the reactor. The reaction liquid in the bottom of the reactor flows through the dehydration component and then returns to the bottom of the reactor.
[0028] like Figure 2The diagram shows a reaction equation within a reactor during a chemical reaction. During this reaction, water is produced within the reactor. The dehydration component can process the water at the bottom of the reactor to prevent it from affecting the reaction process. The specific dehydration method can be distillation or other dehydration methods, which are not specifically limited in this embodiment.
[0029] In some embodiments, the cleaning assembly may further include a cleaning chamber, with a dropper disposed above the cleaning chamber, which is connected to a softened water pipe. The cleaning chamber temporarily stores the cleaned liquid, providing a buffering effect for sedimentation, thereby allowing the liquid in the softened water pipe to flow back into the reactor at a uniform rate.
[0030] In some embodiments, a second valve may be included, one end of which is connected to the first valve, and the other end of which is connected to the diaphragm pump via a sampling line. By providing two consecutive valves, namely the first valve and the second valve between the diaphragm pump and the sampler, it is possible to effectively prevent sampling backflow and the backflow of cleaning fluid into the reactor, thereby increasing system safety.
[0031] In other embodiments, a mobile working platform may be further included, on which the diaphragm pump, detector, and softened water pipeline are arranged. The mobile platform can increase the flexibility and ease of use of the detection assembly and the cleaning assembly.
[0032] In the second aspect, the utility model also provides an ammonium salt synthesis system, including any of the aforementioned continuous automatic detection devices, the reactor includes one or more, and the detector cyclically detects the detection parameters of the material to be detected; the reactor also includes an external cooling circulation system and an exhaust gas treatment system, the external cooling circulation system is configured to be connected to the reaction liquid in the reactor, and the exhaust gas treatment system is configured to absorb the waste gas volatilized in the reactor.
[0033] Among them, the detection end of the detector is an enameled tube, and the enameled tube is set to penetrate into the reactor.
[0034] In this embodiment, a small external loop can be established by using a sampling pipe valve and a 1 / 2 diaphragm pump to transport the sample to the detection system through the sampler, and the detected sample is returned to the kettle; during the process of adding ammonia water to synthesize ammonium salt, the addition is not interrupted and is carried out continuously. During the addition process, the pH in the reactor is controlled and the reaction end point is determined by the pH.
[0035] The detection component performs a pH test on the removed material. During the addition process, the external circulation continues, and the detector continuously monitors the pH value of the circulating material. This data is transmitted back to the DCS system, where the central control operator controls the amount of ammonia added based on the pH value. Furthermore, the pH meter does not need to be cleaned during the batch reaction; it is cleaned only when the pH is acceptable and the addition is complete.
[0036] The cleaning component is on the sampling pipeline, that is, a softened water pipeline with a DN15 is introduced at the inlet of the diaphragm pump. After the cost is completed, the softened water is opened for cleaning for 2 minutes. The cleaning liquid enters the reaction. Since water is generated by the reaction in the synthesis kettle and dehydration operation is to be carried out in the subsequent process, the cleaning liquid entering the kettle has no impact on the product quality; the detection probe of the pH meter is detachable and calibrated regularly.
[0037] Finally, the continuous automatic detection device and ammonium salt synthesis system provided by the present utility model. The detection device includes a sampling component, a detection component, and a cleaning component. The sampling component includes a sampler, a first pipe valve, and a diaphragm pump. The sampling end of the sampler extends deep into the reaction kettle to contact the material to be detected. The other end of the sampler is connected to the first pipe valve. The other end of the first pipe valve is connected to the diaphragm pump through a sampling pipeline. The other end of the diaphragm pump is connected to the detector of the detection component; wherein, after the detector of the detection component completes the detection, it is communicated with the reaction kettle through a softened water pipeline; the cleaning component is arranged in the softened water pipeline and includes a dropper. The cleaning liquid dropped by the dropper is communicated with the reaction kettle through the softened water pipeline. The present utility model can not only continuously detect the monitoring parameters of the material to be detected multiple times, but also has relatively high precision for multiple detections. At the same time, the set cyclic monitoring system maintains the tightness of the reaction kettle without being damaged, improving the quality of detecting the reaction environment parameters of the closed intermittent reaction device and the practicality of the detection.
