Abstract
The utility model discloses a glyphosate deacidification device. The device comprises a dealcholization reactor which is communicated with a chloromethane header pipe through a first fan and a second fan which are connected in parallel, wherein the chloromethane header pipe is communicated with a condenser; the condenser is communicated with a gas-liquid separator; and a third fan is arranged on the outlet pipeline of the gas-liquid separator. Negative pressure is formed in the chloromethane header pipe and the dealcholization reactor and is minus 30-0mm water column. The glyphosate deacidification device provided by the utility model adopts an aerodynamic principle and is additionally provided with two fans; the deacidification terminal temperature is controlled through a micro negative pressure production mode which is formed by the chloromethane header pipe and the dealcholization reactor; and the graphite condenser is additionally arranged on the chloromethane header pipe, and the gas-liquid separator is installed behind the condenser, so that methylal carried by methane gas is further reduced, the recovery rate of the methylal is increased, and moreover, the consumption of the concentrated sulphuric acid is decreased.
Description
Technical field
The utility model belongs to the glyphosate production technical field, is specifically related to a kind of glyphosate deacidifying device.
Background technology
For the production of glyphosate technicals, present manufacturer overflows gases such as the interior methyl chloride of dealcoholysis still, methyl alcohol, methylal for the most pressure-fired modes of production that adopt of the total pipe pressure of glyphosate methyl chloride naturally.But along with the aggravation of deacidification in the still, the still internal pressure rises, and causes thermometric inaccurate, causes material depickling terminal temperature out of control, and depickling is not thorough, influences the glyphosate yield.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is that a kind of utilization aerodynamic principle will be provided, and makes glyphosate material depickling in the dealcoholysis still thorough, improves the glyphosate yield, improve the rate of recovery of methylal, reduce the glyphosate deacidifying device of the consumption of the vitriol oil simultaneously.
The purpose of this utility model is achieved in that a kind of glyphosate deacidifying device, comprise the dealcoholysis still, the dealcoholysis still communicates with the methyl chloride house steward by first blower fan and second blower fan of two parallel connections, the methyl chloride house steward is communicated with condenser, condenser is communicated with gas-liquid separator, is provided with the 3rd blower fan at the gas-liquid separator export pipeline.Be negative pressure in methyl chloride house steward and the dealcoholysis still, pressure is-30～0mm water column.
The glyphosate deacidifying device that the utility model provides, adopt aerodynamic principle, increase by 2 typhoon machines, little negative pressure mode of production control depickling terminal temperature that methyl chloride house steward and dealcoholysis still are formed, increase a graphite condenser the methyl chloride house steward, a gas-liquid separator is installed behind the condenser, further reduce the methylal of carrying secretly in the methyl chloride gas, increase the methylal rate of recovery, reduce the consumption of the vitriol oil simultaneously.
The utility model can make the glyphosate technicals yield improve more than 0.2%, improves the methylal rate of recovery and reaches more than the 20kg/t, and the consumption that reduces the methyl chloride recovery vitriol oil reaches more than the 50kg/t.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the layout of equipment of the present utility model.
Embodiment
Structure of the present utility model is as shown in Figure 1: a kind of glyphosate deacidifying device, comprise dealcoholysis still 1, dealcoholysis still 1 communicates with methyl chloride house steward 4 by first blower fan 2 and second blower fan 3 of two parallel connections, methyl chloride house steward 4 is communicated with condenser 5, condenser 5 is communicated with gas-liquid separator 6, is provided with the 3rd blower fan 7 at the gas-liquid separator export pipeline.
Principle of work of the present utility model is as follows: first blower fan 2, second blower fan 3 and the 3rd blower fan 7 are opened, and make to be negative pressure in methyl chloride house steward 4 and the dealcoholysis still 1, and pressure is-30～0mm water column.The methyl chloride that depickling is come out in the dealcoholysis still 1, methyl alcohol, methylal mixed gas after methyl alcohol, the methylal liquefaction, are collected into dilute methanol storage tank 8 through condenser 5 condensations, go methanol rectification to reclaim; Methyl chloride gas is evacuated to methyl chloride through blower fan and reclaims.
