Abstract

The invention discloses a methanol evaporation and oxidation device for formaldehyde production by a silver method. According to the invention, a gas feeding pipe extends into a methanol evaporator to be fixedly connected with a cover body, the lower portion of the cover body is located in a gas circulation direction adjusting piece, and the gas circulation direction adjusting piece is fixed in the methanol evaporator through a fixing device; the methanol feeding pipe extends into the methanol evaporator and is fixedly connected with an annular storage pipe, the lower end of the storage pipe is fixedly provided with a plurality of methanol guide pipes, the lower ends of the methanol guide pipes are fixedly connected with atomization nozzles, and the atomization nozzles are located between the cover body and the gas circulation direction adjusting piece; and a soft water feeding pipe extends into the methanol evaporator to be fixedly connected with an annular water storage pipe, a plurality of water outlet pipes are fixedly arranged at the lower end of the water storage pipe, and atomization nozzles are fixedly connected to the lower ends of the water outlet pipes and located between the gas circulation direction adjusting piece and the inner side wall of the methanol evaporator. According to the invention, methanol, air, circulating tail gas and soft water can have a better mixing effect in the methanol evaporator.

Description

technical field [0001] The invention relates to the technical field of chemical production equipment, in particular to a methanol evaporation and oxidation device for silver-based formaldehyde production. Background technique [0002] Methanol evaporator is a kind of chemical equipment commonly used in the process of preparing formaldehyde by silver method. The methanol evaporator in the prior art usually has the problem of poor mixing effect when realizing the mixing of vaporized methanol, batching steam and tail gas. For this reason, the applicant has developed a methanol evaporation and oxidation device for the production of formaldehyde by silver method. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the invention provides a methanol evaporation and oxidation device for silver-based formaldehyde production. [0004] Technical scheme of the present invention is: [0005] A methanol evaporation and oxidation device for si...
