Description

Technical Field

[0001] The invention relates to the technical field of waste liquid treatment, and more specifically to a highly efficient purification device for NMP waste liquid. Background Art

[0002] In the process of manufacturing lithium batteries and other materials, a large amount of NMP waste liquid will be generated. In order to save production costs and maintain the concept of recycling, the NMP solution generated by the production needs to be purified. The purification of the NMP solution requires the use of an NMP waste liquid efficient purification device. The NMP waste liquid efficient purification device is a device that purifies the NMP solution by distillation and condensation. The NMP waste liquid efficient purification device is mainly composed of a shell component, a connecting component, a distillation component and a condensation component. The NMP waste liquid efficient purification device has the advantages of fast purification speed and good purification effect.

[0003] The common NMP waste liquid high-efficiency purification device generally has the following defects during use:

[0004] First, in the process of using the common NMP waste liquid high-efficiency purification device, before purification, the NMP solution to be purified needs to be injected into the purification device. After the solution is injected, it needs to be opened manually. The whole process needs to be controlled manually, and the operation process is relatively complicated, which takes a lot of time and reduces the efficiency of purification.

[0005] Second, in the process of using the common NMP waste liquid high-efficiency purification device, it is impossible to accurately judge whether the gas generated by distillation is inside the condenser during the distillation process. In order to ensure the condensation, cold water is generally injected around the condenser, resulting in a waste of resources.

[0006] Thirdly, in the process of using the common NMP waste liquid high-efficiency purification device, since NMP needs to be easily distilled and condensed, a high temperature will be generated during the distillation of the NMP solution. Other personnel will be burned by the high temperature due to their ignorance and failure to stay away in time, which is dangerous.

[0007] In summary: the common NMP waste liquid high-efficiency purification device has the following defects during use: after the solution injection is completed, it needs to be opened manually, the whole process needs to be controlled manually, the operation procedure is relatively complicated, and it takes a lot of time, which reduces the efficiency of purification. In order to ensure the condensation, cold water is generally injected around the condenser tube, resulting in a waste of resources.

When the air pressure measuring device on the lower surface of the baffle detects that the pressure inside the processing tank reaches the standard, it will send a signal to the water injection pipe. After receiving the signal, the water injection pipe will inject cold water into the condensation tank through the water injection pipe and the water inlet pipe. At the same time, the steam inside the processing tank will pass through the connecting pipe and the filter plate to be filtered, and enter the condensation pipe through the gas pipe. Under the action of cold water, the distilled gas is condensed. The gas generated by the condensation will be collected by the collector at the outlet end of the condensation pipe. When no steam is generated, the air pressure measuring device on the lower surface of the baffle detects that the pressure inside the processing tank does not reach the standard, and the water injector will not work, thereby saving the use of resources.

When the lifting block contacts the sensor at the bottom of the lifting slot, the sensor receives a signal, and the sensor sends a signal to the alarm.

[0033] The present embodiment needs to be particularly explained that: when the NMP waste liquid needs to be purified, the NMP waste liquid to be purified is injected into the processing tank 301 through the feed port 405. As the NMP waste liquid is continuously injected into the processing tank 301, the processing shell 3 will descend. The descending of the processing shell 3 will drive the lifting plate 408 and the telescopic plate 411 to descend together through the lifting block 407.

As the NMP waste liquid is continuously injected into the processing tank 301, the processing shell 3 will descend. The descent of the processing shell 3 will drive the lifting plate 408 and the telescopic plate 411 to descend together through the lifting block 407. As the processing shell 3 continues to descend, when the feed port 405 is blocked by the support ring 404, the injection of the NMP waste liquid is stopped.

The sensor will receive a signal, and the telescopic plate 411 will move out from the inside of the telescopic slot 410, thereby realizing the connection between the telescopic slot 410 and the heat conducting slot 413.

[0046] The working principle of the present invention is as follows: when the NMP waste liquid needs to be purified, the NMP waste liquid to be purified is injected into the processing tank 301 through the feed port 405. As the NMP waste liquid is continuously injected into the processing tank 301, the processing shell 3 will descend.

[0047] After the NMP waste liquid in the processing tank 301 is distilled, the gas generated by the distillation will rise. When the barometer on the lower surface of the baffle 501 detects that the pressure inside the processing tank 301 reaches the standard, it will send a signal to the water injection pipe 507. After receiving the signal, the water injection pipe 507 will inject cold water into the condensation tank 510 through the water injection pipe 507 and the water inlet pipe 508. At the same time, the steam inside the processing tank 301 will pass through the connecting pipe 502 and the filter plate 503 for filtration, and enter the condensation pipe 511 through the gas pipe 504.
