Description

Technical Field

[0001] This utility model relates to the technical field of strong acid reaction equipment, and in particular to a continuous flow device for processing strong acid reaction systems. Background Technology

[0002] Currently, approximately 70% of the treatment of strongly acidic reaction solutions globally relies on traditional batch reactor processes. The core operating mode involves manually adding alkaline neutralizing agents (such as sodium hydroxide, limestone, and magnesium oxide) to the acidic medium in batches using experience or semi-automatic metering pumps (with a dosing accuracy of ±5%). Mechanical stirring (50-150 rpm) is used to achieve the acid-base mixing reaction, and manual sampling is required to periodically test the pH value (each test takes 15-30 minutes) until the system reaches neutral or weakly alkaline (pH 6.5-8.5). However, with the stringent requirements of Industry 4.0 for production efficiency (Overall Equipment Effectiveness (OEE) needs to be increased to over 85%), resource utilization (neutralizing agent utilization needs to reach over 95%), and intrinsic safety (accident response time needs to be shortened to within 1 second), the technological shortcomings of this type of process have gradually become a core contradiction restricting industrial upgrading.

[0003] Therefore, a continuous neutralization treatment device for a strongly acidic reaction system is proposed. Utility Model Content

[0024] Please see Figure 1 This utility model provides a technical solution: a continuous flow device for treating a strongly acidic reaction system, comprising:

[0025] The heating jacket heat exchange system 1, reaction chamber 2, metering pump 3, high pressure feed pump 4, intelligent feedback control system 7, and SK type stirred mixer 5 are used to control the heat exchange of the heating jacket on the SK type stirred mixer 5.

[0026] The discharge end of the reaction chamber 2 is connected to the feed end of the SK-type stirred mixer 5. The discharge ends of the metering pump 3 and the high-pressure feed pump 4 are both connected to the feed end of the SK-type stirred mixer 5. A pH detector 6 is fixedly installed on the SK-type stirred mixer 5. The intelligent feedback control system 7 is electrically connected to the pH detector 6 and the intelligent feedback control system 7 is electrically connected to the metering pump 3.

[0027] The feed end of metering pump 3 is used to transport alkaline solution 10, the feed end of high pressure feed pump 4 is used to transport strong acid reaction solution 9, the top of pH detector 6 is fixedly connected to discharge pipe 8, and SK type stirring mixer 5 is made of Hastelloy material.

[0028] Furthermore, when using this device, the high-precision metering pump 3 accurately delivers the neutralizing agent to the reaction system according to the preset addition ratio and reaction requirements. The addition accuracy of the metering pump 3 is controlled within a very small range. The continuous flow device is equipped with an SK-type stirred mixer 5, which makes the liquid form a complex flow state in the reactor, enhancing the contact area and mixing effect between acids and bases. The reaction time of the continuous flow device can be adjusted within the range of 1-30 minutes, and the operating temperature range is -20℃ to 200℃.

[0029] The continuous flow device is made of Hastelloy material, which has corrosion resistance, high pressure resistance and high temperature resistance, and can withstand the high corrosiveness of acidic reaction liquids and high temperature and high pressure environment.

[0030] The high-pressure feed pump 4 stably delivers the acidic reaction liquid to be neutralized to the subsequent reaction stage, and the conveying equipment can adapt to acidic reaction liquids of different viscosities and properties.

[0031] pH detector 6 can quickly and accurately acquire pH data in the reaction system and transmit the data to intelligent feedback control system 7.

[0032] The intelligent feedback control system 7 is linked with the pH detector 6 and the metering pump 3. When the real-time pH monitoring unit detects that the pH value of the reaction system deviates from the target range, the intelligent feedback control system 7 responds within a specified time and dynamically adjusts the dosing rate of the neutralizing agent to stabilize the pH value of the reaction system within the target range (pH value 6.5-8.5).

[0033] Through the design of multi-stage mixing reaction modules and continuous flow devices, efficient mixing and rapid neutralization of acidic reaction solutions and neutralizing agents are achieved, greatly shortening reaction time and improving processing efficiency. The combination of a real-time pH monitoring unit and an intelligent feedback control system enables real-time monitoring and precise adjustment of the pH value of the reaction system, ensuring that the reaction process is always in the optimal state and that the product quality is stable and reliable.

[0034] The fully enclosed reaction device avoids leakage and splashing of highly acidic liquids, effectively reducing the risk of operators coming into contact with corrosive substances and ensuring the occupational health and safety of operators. At the same time, the device's safety interlock module can respond to abnormal situations in a timely manner, further improving the safety of the device. Precise neutralizer metering and efficient mixing reaction ensure that the neutralizer is fully utilized, with the neutralizer utilization rate increasing to over 98%, reducing resource waste and lowering production costs.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
