Environment-friendly nitration reactor

Abstract

The invention relates to the technical field of nitration reaction, and discloses an environment-friendly nitration reactor, which comprises a reaction kettle, a driving motor, a heat exchange jacket, a water inlet pipe, a water outlet pipe, a feeding port and a discharging port, wherein the driving motor is fixed to the top of the reaction kettle through a mounting frame, the reaction kettle is fixedly sleeved with the heat exchange jacket, the side wall of the bottom end of the heat exchange jacket is communicated with the water inlet pipe, the side wall of the top end of the heat exchange jacket is communicated with the water outlet pipe, the side wall of the reaction kettle is communicated with the feeding port, the bottom of the reaction kettle is communicated with the discharging port, and the interior of the reaction kettle is divided into a waste gas treatment cavity and a nitration reaction cavity from top to bottom through a partition plate. According to the environment-friendly nitration reactor, materials in the reaction kettle can be conveniently stirred in all directions, so that stirring dead angles are avoided, the nitration reaction effect is improved, nitrogen oxide waste gas generated in the nitration reaction process can be conveniently absorbed and treated, environment pollution is avoided, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of nitration reaction, in particular to an environment-friendly nitration reactor. Background technique [0002] The nitration reaction of aromatic hydrocarbons is one of the earliest and most common chemical reactions in industry. The mononitro compounds produced are the most important chemical intermediates in modern organic chemical industry, and are widely used in the fields of medicine, dyes, pesticides and spices. [0003] During the process of catalytic nitration inside the reactor, it is necessary to use the stirring blades to fully mix the internal materials. In the prior art, the stirring blades inside the reactor are all fixed positions, and the materials in the reactor cannot be adjusted during the stirring process. Omni-directional stirring will easily affect the nitrification reaction effect, and the nitrogen oxide waste gas generated during the nitrification reaction will easily pollute the en...
