Description

Technical Field

[0001] The invention relates to the technical field of electrolytic cell equipment for producing heptafluorobutyryl fluoride, and in particular to a heptafluorobutyryl fluoride electrolytic cell which is convenient for material collection. Background Art

[0002] Heptafluorobutyryl fluoride is a colorless to pale yellow liquid with low flammability. It is relatively stable at room temperature, but should be avoided from contact with strong oxidants or strong bases. Heptafluorobutyryl fluoride is an important chemical intermediate, mainly used in organic synthesis reactions, and can also be used as a surfactant in electronic materials to improve coating and adhesion properties.

[0003] The existing technology for preparing heptafluorobutyryl fluoride adopts a direct electrolytic fluorination method, where n-butyryl chloride and hydrogen fluoride are fed into a low-voltage direct current in an electrolyzer, generating free fluorine atoms to directly replace the hydrogen atoms and chlorine atoms in n-butyryl chloride, and then the heptafluorobutyryl fluoride product is obtained through a simple purification process. During operation, the heptafluorobutyryl fluoride electrolyzer is used to facilitate its local overhaul process, and other units can also perform electrolytic operations. The existing electrolyzer body is generally separated into several independent electrolytic regions by corresponding partitions, and in order to facilitate unified product collection, the bottom of each electrolytic region is connected again. The connection arrangement between the bottoms of each electrolytic region, although it realizes the unified collection of products, also causes the electrolytic processes between each electrolytic region to affect each other, thereby causing adverse effects on production.

[0004] Therefore, the research purpose of the present invention is to design a heptafluorobutyryl fluoride electrolytic cell that can effectively form a closed isolation for each electrolysis area to prevent excessive mutual influence between the electrolysis processes of each electrolysis area, and can uniformly harvest the products produced by each electrolysis area as usual, so as to facilitate the collection of materials.

The air inlet end of the inflation pipe is connected to an external nitrogen source, and the inflation pipe is connected to a pressure relief pipe equipped with a pressure relief valve.

[0011] The plug body comprises a bottom cover, and the bottom cover is upwardly sealed and connected with a corresponding upper cover.

[0012] The bottom cover is upwardly sealed and connected to the upper cover via corresponding elastic members.

[0013] A pressure sensor with a detection end abutting against the bottom side of the upper cover is fixedly mounted on the bottom cover.

[0014] When the pressure value detected by the pressure sensor is greater than F1, the external nitrogen source is pumped into the bellows through the inflation pipe to lift the plug upward; then, the pressure relief valve is opened to release the pressure, and the plug is reset downward; the inflation and pressure relief are repeated to discharge the products deposited and collected in the aggregate plate; when the pressure value detected by the pressure sensor is less than F2, the pressure relief valve is opened to release the pressure, and no more inflation is performed.

[0015] The bottom of the electrolytic cell body is arranged obliquely, and a discharge pipe with a discharge valve installed is fixedly connected to the bottom end of the electrolytic cell body.

[0019] Advantages of the present invention:

[0020] 1) The present invention can further form a closed isolation for each electrolysis area at the bottom side of each electrolysis area through the setting of the unloading mechanism, so as to prevent the electrolysis processes between different electrolysis areas from excessively affecting each other; when unloading, the external nitrogen source is pumped into the bellows through the inflation pipe to lift the plug upward; then, the pressure relief valve is opened to release the pressure, so that the plug can be reset downward; by repeating the inflation and pressure relief, the products deposited and collected in the collecting plate can be discharged smoothly, which is very convenient, so that the products produced by each electrolysis area can be uniformly harvested as usual.

[0021] 2) The present invention further configures the plug body to be a bottom cover and an upper cover elastically connected by an elastic member, and then a pressure sensor with a detection end abutting against the bottom side of the upper cover is fixedly installed on the bottom cover.

[0030] A material discharge mechanism 6, wherein corresponding isolation plates 7 are fixedly connected to the electrolytic cell body 1 between two adjacent electrode cover plates 3, and the bottom of the isolation plates 7 is spaced apart from the bottom of the electrolytic cell body 1. The material discharge mechanism 6 comprises a material collecting plate 601 fixedly connected to the bottom of the space formed by the isolation plates 7 and the electrolytic cell body 1, and corresponding material discharge holes are respectively arranged in the middle of the material collecting plate 601, and corresponding plug bodies 602 are respectively installed at the material discharge holes in a lifting manner;

[0031] The driving mechanism 8 is used to drive the plug body 602 to rise and fall. The driving mechanism 8 includes a bellows 801 that is sealed and connected to the bottom of the electrolytic cell body 1. The end of the bellows 801 that is not connected to the electrolytic cell body 1 is fixedly connected to the corresponding plug body 602.

The inflation pipe is connected to a pressure relief pipe 803 equipped with a pressure relief valve 9.

[0032] The present invention can further form a closed isolation for each electrolysis area at the bottom side of each electrolysis area by setting the unloading mechanism 6, so as to prevent the electrolysis processes between different electrolysis areas from excessively affecting each other; when unloading, the external nitrogen source is pumped into the bellows 801 through the inflation pipe 802 to lift the plug body 602 upward; then, the pressure relief valve 9 is opened to release the pressure, so that the plug body 602 can be reset downward; by repeating the inflation and pressure relief, the products deposited and collected in the collecting plate can be discharged smoothly, which is very convenient, so that the products produced by each electrolysis area can be uniformly harvested as usual.

When the pressure value detected by the pressure sensor 10 is greater than F1, an external nitrogen source is pumped into the bellows 801 through the inflation pipe 802 to lift the plug body 602 upward; then, the pressure relief valve 9 is opened to release pressure, and the plug body 602 is reset downward; the inflation and pressure relief are repeated to discharge the products deposited and collected in the collecting plate 601; when the pressure value detected by the pressure sensor 10 is less than F2, the pressure relief valve 9 is opened to release pressure, and no more inflation is performed.

[0034] The present invention further configures the plug body 602 to be a bottom cover 6021 and an upper cover 6022 elastically connected by an elastic member 6023, and then a pressure sensor 10 with a detection end abutting against the bottom side of the upper cover 6022 is fixedly installed on the bottom cover 6021. When the pressure value detected by the pressure sensor 10 is greater than F1, it can be determined that the amount of products deposited and collected in the collection plate 601 has reached the design value, and at this time, the discharge operation can be performed; when the pressure value detected by the pressure sensor 10 during the discharge is less than F2, it can be determined that the products deposited and collected in the collection plate 601 have been basically discharged, and at this time, the discharge operation can be stopped. In this way, the discharge cycle can be effectively and accurately controlled to improve the use effect of the present invention.

[0035] The bottom of the electrolytic cell body 1 is tilted, and a discharge pipe 12 with a discharge valve 11 is fixedly connected to the bottom of the electrolytic cell body 1 to facilitate the unified collection of products produced from multiple electrolysis areas.
