Embodiment 1

[0034] Salting out and drying treatment of pyridine aqueous solution with potassium hydroxide: prepare potassium hydroxide particles in the solid feed bin 7, open the solid feeding valve 8, and fill the drying section 5 with potassium hydroxide B, which has a water content of 42%. Pyridine aqueous solution A is pumped in with the feed pump 1, and the liquid level rises slowly. When the liquid touches the solid particles at the lower end of the drying section 5, the solution begins to dissolve potassium hydroxide. At this time, the solid feeding valve 8 is opened to stabilize the drying section 5. After the potassium hydroxide dissolved in the solution reaches a certain concentration, the feed liquid is layered, and the discharge of the waste water discharge pump 9 is adjusted through the oil-water interface meter to control the oil-water two-phase interface in the middle of the interface control section 4, and the pyridine aqueous solution A passes through the inlet The materia...

Embodiment 2

[0036] Triethylamine acetate aqueous solution is salted out with sodium hydroxide, drying treatment: the operation in embodiment 1 is basically the same, solid particles and aqueous solution are changed into sodium hydroxide and triethylamine acetate aqueous solution, and In the salting-out section, there is a chemical reaction and heat is released. It is necessary to add a jacket to the lower part of the tower and pass cooling water to cool down; the others are the same. The triethylamine acetate aqueous solution with a water content of 60% is subjected to alkali analysis and drying to obtain triethylamine with a water content of less than 0.1%, with a yield of 97%.

Abstract

The invention discloses a continuous salting-out and drying device and a use method thereof. The device comprises a solid stock bin, a solid discharging valve, a salting-out and drying tower, a feeding pump and a waste water discharging pump, wherein the salting-out and drying tower comprises five parts sequentially including the followings from top to bottom: an oil phase standing section, a drying section, an interface control section, a salting-out section and a waste water standing section; an outlet of the solid stock bin is connected with the upper part of a drying layer of the drying section of the salting-out and drying tower and the lower end of the oil phase standing section; the drying section of the salting-out and drying tower is filled with solid material particles; a sieve plate for supporting and intercepting the solid material particles is arranged at the lower end of the drying section; the solid discharging valve is arranged at the bottom of the solid stock bin; an outlet of the feeding pump is connected with the bottom end of the salting-out section of the salting-out and drying tower and the upper part of the waste water standing section; the waste water discharging pump is arranged at the bottom of the waste water standing section of the salting-out and drying tower. The device can realize continuous water removing operation and improves production efficiency and equipment utilization rate.

Description

technical field [0001] The invention relates to a salting-out drying device. Background technique [0002] Salting-out generally refers to the process of adding inorganic salts to the solution to reduce the solubility of a certain substance and precipitate it. The existing process is to put the solution into the reactor, put in the inorganic salt, stir, stand, and layer; drying generally has There are two types, one is to spread the desiccant on the filter, and then put the supernatant into the filter to filter, and the other is to add the desiccant to the reaction kettle, stir and let stand, and dry. [0003] In the prior art, the two operations of salting-out and drying are operated separately in the tank reactor, usually manually, with complex process, long process flow, large equipment, many supporting equipment, large amount of operation, and complicated operation , The working environment is poor. Contents of the invention [0004] The purpose of the present invent...
