The utility model discloses can make the reaction gas evenly distributed who gets into reactor react in getting into the catalyst layer, in addition because being equipped with circulating cooling water pipe in the catalyst layer, can preventing that the catalyst layer is overheated, the recirculated cooling water groove is placed in to the tubulation cooler, can make reaction gas autocatalysis agent layer come out to cool off the 100 -130 degree and control, but can not reach higher temperature, has prevented that formaldehyde from taking place side reactions such as deep oxidation under high temperature.
Description
Technical field
The utility model belongs to silver-colored formaldehyde production technical field, is specifically related to a kind of oxidation reactor used for formaldehyde production.
Background technology
In the production process of silver legal system formaldehyde, air capacity, reaction effect between water vapour amount and methyl alcohol evaporation capacity have impact on efficiency and the quality of formaldehyde processed greatly, it directly affects the reaction temperature of oxidator, product quality, output, the consumption of raw material, the problem such as catalyst life and production safety, so just there is strict requirement to oxidator, the catalysis of silver method is due to variations in temperature, easily poly-reaction, cause occurring crack, affect production and the making of formaldehyde, wherein in oxidation reaction, the position of catalyst and oxidizing temperature change are sport technique segments particularly important in oxidation reaction, reaction temperature rises too fast, reaction speed is accelerated, but the too high meeting of reaction temperature causes side reaction to increase, impurity is too many, be unfavorable for that the life-span of catalyst is unfavorable, reaction temperature is too low, reaction speed is slower, do not reach productive target, so the control of oxidator also seems particularly important.
Utility model content
The purpose of this utility model is solve above-mentioned technical problem and provide one can prevent formaldehyde from the side reactions such as deep oxidation oxidation reactor used for formaldehyde production at high temperature occurring.
For achieving the above object, the utility model adopts following technical scheme:
A kind of oxidation reactor used for formaldehyde production, comprise reactor body, described reactor body has reacting gas inlet, reaction gas outlet, there is in described reactor body catalyst reaction section and be located at the quench zone of described catalytic reaction pars infrasegmentalis, described catalyst reaction section comprises catalyst layer, described quench zone comprises tubulation cooler, circulating cooling water pipe is provided with in described catalyst layer, described tubulation cooler is placed in circulating cooling tank, the top of described catalyst reaction section is provided with even gas distribution device, described even gas distribution device is cone-shaped structure, surface is provided with multiple airflow hole.
Described circulating cooling tank connects cooling water inlet and the coolant outlet of recirculated cooling water.
