An experiment about 2-fluoroaniline

This experiment provides a feed nozzle for a rectifying tower for producing 2-fluoroaniline, which comprises a connecting pipe, a swivel head and oblique nozzles, wherein the feed nozzle is arranged at the top of the rectifying tower for producing 2-fluoroaniline(CAS NO:348-54-9), the bottom of the connecting pipe is provided with a connecting part, the swivel head is connected with the connecting part of the connecting pipe, the swivel head is provided with the oblique nozzles, and the oblique nozzles are circumferentially arranged around the swivel head. According to the utility model, through the improvement on a nozzle for a rectifying tower for producing m-fluoroaniline, the high-speed rotation of the nozzle is formed by using airflows, so that materials are uniformly dispersed in the rectifying tower.

Distillation is the production of o-fluoro-aniline is an important part, distillation is the chemical industry, petroleum industry, infrastructure, distillation has a feeding device, currently used by the refiner is a direct use of the material nozzle into the distillation column, so that transportation of materials is often not uniform, this will be the production of o-fluoro-aniline dramatic effect, therefore, it would improve the structure of the nozzle so that the material into more uniform, can greatly improve production efficiency and product quality.

To solve the above problems, the present utility model produced by the distillation nozzle adjacent Fluoroaniline improvements, the use of high-speed rotating airflow nozzle makes the material to form a uniform dispersion to distillation column, in order to achieve this goal, the utility model provides a seed production of Fluoroaniline distillation column with feed spout, including connecting pipes, swivel head and oblique spout, said feed nozzle installed in the production of the distillation column adjacent Fluoroaniline top bottom of the connection pipe connecting section , said rotary head and connecting pipe connecting portion connected to said rotary head with oblique spout, spout rotate about the first week of oblique setting.

As a further improvement of the utility model, the oblique spout with 4-6, the patent can be set according to the material flow corresponding number of oblique spout.

This utility model as a distillation of aniline production of o fluoride feed nozzle with the nozzle head has a plurality of helical rotary nozzle, the material into after falling from ramp nozzle to swivel head opposite force, After rotating the rotary head thrown distillation column material, in this way has been tested not only feed the feed evenly, and the feed speed, especially for the production of o-fluoro-aniline.

This utility model produced by the distillation nozzle adjacent Fluoroaniline improvements, the use of high-speed rotating airflow nozzle makes the material to form a uniform dispersion to distillation column.

This utility model as one particular embodiment, the present utility model structure provides a process for producing o-fluoro aniline distillation with feed spout, including connecting tube 1, 2, and oblique spout swivel head 3, the feed nozzle installed in the production of o-fluoroaniline top of distillation column, the bottom of the connection pipe connecting portion 1-1 I, said rotary head 2 and the connecting pipe connecting portion 1-1 is connected to I, the said rotating nozzle head 2 has three ramps, the ramp nozzle 3 with 4-6, the patent can be set according to the material flow corresponding number of oblique spout, spout 3 is rotated about said slant head 2 - week setting. 

This utility model as a distillation of aniline production of o fluoride feed nozzle with the nozzle head has a plurality of helical rotary nozzle, the material into after falling from ramp nozzle to swivel head opposite force, After rotating the rotary head thrown distillation column material, in this way has been tested not only feed the feed evenly, and the feed speed, especially for the production of o-fluoro-aniline.

Above, the utility model is only preferred embodiments, the utility model is not used for any other form of restriction, and the technical basis for the utility model made any substantive changes to modify or equivalent, still belong to the utility of the claimed ranges.
