Background
The esterification reaction kettle is a device for carrying out material esterification reaction, and the esterification reaction is a kind of organic chemical reaction, namely the reaction of alcohol and carboxylic acid or oxygen-containing inorganic acid to generate ester and water. The existing esterification reaction kettle usually uses concentrated sulfuric acid as a catalyst, and a stirring device is arranged to stir materials, so that the materials are uniformly mixed and the reaction is accelerated.
However, when the reaction is carried out on different materials, the stirring is still not uniform enough and the ester conversion is not high. Mineral acids can cause a series of corrosion problems in production. Therefore, a novel resin is provided as an esterification reaction kettle of the catalyst.
Therefore, the utility model is especially provided.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a resin catalyst esterification reaction cauldron realizes that the resin catalyst fully reacts in reation kettle, improves conversion efficiency.
In order to solve the above problem, an embodiment of the utility model provides a resin catalyst esterification reaction kettle, a serial communication port, include:
a kettle body;
a support grid; the support grid is horizontally arranged in the kettle body and divides the space in the kettle body into an upper part and a lower part; a resin catalyst is laid on the support grid;
the upper half part of the kettle body is provided with a resin loading port, and the lower half part of the kettle body is provided with a resin unloading port;
the latter half of the cauldron body is equipped with the feed inlet, and the top is equipped with the discharge gate.
Further, a water distributor is arranged at the bottom in the kettle body and is connected with the feed inlet.
Further, a resin trap is arranged at the top in the kettle body and connected with the discharge hole.
Further, the resin trap includes a fixed disk and a filter cartridge connected below the fixed disk.
Further, the width of the slits of the support grid is smaller than the particle diameter of the resin catalyst.
Compared with the prior art, the utility model discloses a following beneficial effect has: the resin catalyst arranged on the support grid in the kettle, when in esterification reaction, the feed liquid enters the kettle to slowly flow upwards and fully and uniformly contact the resin catalyst on the support grid, thereby improving the reaction conversion rate. The reaction kettle has the advantages of reasonable structure, low energy consumption, convenient operation and great production efficiency.

Detailed Description
The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments shown in the drawings. It should be understood that these embodiments are described only to enable those skilled in the art to better understand the invention and to implement the invention, and are not intended to limit the scope of the invention in any way.
Referring to fig. 1-2, an embodiment of the present invention provides a resin catalyst esterification reaction kettle, which includes a kettle body 9, wherein the top end of the kettle body 9 is an upper end enclosure, and the bottom end is a lower end enclosure. A horizontal supporting grid 3 is arranged in the kettle body 9, and the kettle body 9 is divided into an upper part and a lower part, namely an upper half part and a lower half part.
Feed inlet 1 sets up in the latter half of the cauldron body 9, specifically sets up at the low head. The discharge hole 7 is arranged at the upper half part of the kettle body 9, and is specifically arranged at the upper end enclosure.
The support grid 3 is laid with a resin catalyst 5 for contacting the feed liquid entering the feed inlet 1.
The water distributor 2 is arranged at the bottom in the kettle body 9, the water distributor 2 can be welded at a lower end socket and is connected with the feed inlet 1, so that feed liquid enters the kettle body 9 and is uniformly distributed, and the feed liquid can be more fully contacted with the resin catalyst 5 on the support grid 3.
In order to facilitate the maintenance and cleaning of each structure in the tank and the filling of resin, a resin filling port 6 is arranged at the upper half part of the kettle body 9. The lower half part of the kettle body 9 is provided with a resin discharging port 4. For example, the resin filling port 6 may be provided on the side of the upper half of the vessel body 9. Unload resin mouth 4 and set up the side in cauldron body 9 the latter half, and can be the slant and arrange, make things convenient for the resin of discharging.
In order to prevent the resin from flowing out of the discharge port 7, a resin catcher 8 is connected to one side of the discharge port 7 close to the inner part of the kettle body 9 and used for intercepting resin particles. In the present embodiment, the resin trap 8 includes a fixed disk 10 and a filter cartridge 11 attached below the fixed disk 10. The fixed disc 10 is used for connecting with the discharge port 7, and the filter cartridge 11 is used for enabling feed liquid after esterification to enter and intercepting resin particles.
The support grids 3 may be fixed inside the kettle body 9, and the width of the gaps of the support grids 3 is smaller than the particle diameter of the resin catalyst 5, preventing the particles of the resin catalyst 5 from falling.
When the resin catalyst esterification kettle provided by the invention is used, the resin filling port 6 is opened firstly, the resin filling port enters the kettle body 9 to install the support grid 3, then the resin catalyst is filled from the resin filling port 6, the resin filling port 6 is closed, reaction liquid enters from the feeding port 1, is distributed by the water distributor 2 and slowly rises to the support grid 3 to react in the resin catalyst 5, and a product flows out from the top discharging port 7.
Further, after the life of the resin catalyst 5 has expired, the resin in the pot is discharged from the resin discharge port 4.
The present invention has been described in detail with reference to specific embodiments, and the description of the embodiments is only for the purpose of helping understanding the core idea of the present invention. It should be understood that any obvious modifications, equivalents and other improvements made by those skilled in the art without departing from the spirit of the present invention are intended to be included within the scope of the present invention.
