Production apparatus for nitromethane

Abstract

The invention relates to the field of chemical engineering and especially discloses a production apparatus for nitromethane. The production apparatus comprises a synthesis reaction tower, a separating tower, a dehydrating tower and a rectifying tower. A synthesis reaction tower material inlet at the central part of the synthesis reaction tower is communicated with a material source through a pipeline, and a synthesis reaction tower material outlet at the bottom of the synthesis reaction tower is communicated with a separating tower first feed inlet at the central part of the separating tower via a material pump through pipelines, and a separating tower top discharge outlet at the top of the separating tower is communicated with a first intermediate tank feed inlet at the top of a first intermediate tank via a third condenser through pipelines. The production apparatus for nitromethane has the following beneficial effects: continuous production of a whole production line is realized, the level of automatic control is substantially increased, labor intensity is mitigated, production is safer, more efficient and environment-friendlier, a synthesis reaction is more complete, more uniform and more thorough, energy consumption is reduced, and product quality is improved.

Description

(1) Technical field [0001] The invention relates to the field of chemical industry, in particular to a device for producing nitromethane. (2) Background technology [0002] Nitromethane is an old chemical product, and its production process has not been greatly improved and innovated since the mass production of the product. Up to now, domestic and foreign nitromethane production processes all use reactors for batch and intermittent operations. Batch and intermittent production has low production capacity, poor quality, high labor intensity, high energy consumption, and low safety and environmental protection coefficient. And other shortcomings, the entire production line cannot be fully automated, continuous operation and continuous production, the original production process has been far from meeting the production and development needs of modern enterprises, seriously restricting the large-scale and scientific development of the industry. (3) Contents of the invention ...
