GRADIENT-FREE REACTOR Russian patent published in 2007 - IPC B01J19/18 

FIELD: chemical industry; other industries; apparatuses for realization of continuous processes.

SUBSTANCE: the invention is pertaining to the apparatuses for realization of the continuous processes, for example, for the processes of nitration treatment of urotropin with the nitric acid in the vinegar-anhydride medium, and may find application in the field of production of the blasting explosives, chemical and other industries. The gradient-free reactor contains: the body, inside of which there are the heat-exchanger-diffuser and the stirring device; the cover, the bottom and the fitting pipes for the raw and the coolant feeding in and withdrawal of the reaction products and the coolant. For the purpose of raising the productivity due to the increase of the operational life of the reactor the heat-exchanger-diffuser is supplied with the arranged in the upper part and connected to the fitting pipes of the coolant feeding in and withdrawal the damper chamber, along the axis of which the stirring device is arranged. The technical result of the invention is the increase of the operational life of the reactor at the continuous realization of regeneration of the surface of the heat exchanger.

EFFECT: the invention ensures the increase of the operational life of the reactor at the continuous realization of regeneration of the surface of the heat exchanger.
