Abstract
The invention discloses a method for recovering a condensed fluid of a glyphosate synthesis solution. Glyphosate technical wet powder enters into a main drying tower for drying through a feeding device and enters into a cyclone drying tower for drying to obtain qualified glyphosate technical. The method is characterized in that the material from the cyclone drying tower enters into a cyclone separator, the powder separated by the cyclone separator reenters into the main drying tower under the action of a fan to be mixed with the glyphosate technical wet powder in the main drying tower, and the mixture is dried. According to the method, the low-content powder with high premium grade rate is returned into the main drying tower to be mixed with the wet powder and the mixture is dried by adopting the high-pressure fan and a stainless steel air pipe, so that the powder is uniformly dispersed in the glyphosate technical for packaging. Therefore, the premium grade rate of the glyphosate technical is increased by 2%, the recovery rate of the technical is more than 99.9%, the powder is greatly reduced, the production environment is optimized, and the loss of steam and the like is reduced by 20% year on year.
Description
Technical field
The present invention relates to the glyphosate production technical field, be specifically related to that powder is returned to the method that is mixed into qualified glyphosate technicals in the production system in a kind of glyphosate technicals dry run.
Background technology
The drying means of present glyphosate technicals, the technique that generally adopts is the vapor heat exchanger heat exchange air, through air blast hot-air is blasted in the main drying tower again, the glyphosate wet-milling is kicked up by hot whirlwind in main drying tower and is blown in the cyclone drying tower, blowing namely gets qualified glyphosate technicals at the bottom of the cyclone drying Tata, and the hot whirlwind of cat head is drawn in the cyclone separator with the powder of low content, high high-grade-goods rate.Blowing namely gets the glyphosate powder at the bottom of the cyclone separator tower, and the hot whirlwind of cat head is brought into the glyphosate dust of minute quantity and carries out filtered and recycled in the sack cleaner, then enters emptying after the washing in the foam dust collector.In this production process, the powder that reclaims at the bottom of the cyclone separator tower, can not sell as qualified glyphosate technicals owing to its glyphosate contains quantity not sufficient though high-grade-goods rate is higher, can only undersell or be made into the gyphosate solution of income microcosmic and sell, these have all caused glyphosate technicals drying process energy consumption height, wastage of material, production capacity is low, yield is low.
Summary of the invention
For the deficiencies in the prior art, purpose of the present invention is exactly that the energy consumption that reduces the glyphosate technicals drying with a kind of will be provided, and improves the method for the dry returning charge recovery of glyphosate technicals of raw material availability and production capacity.
The object of the present invention is achieved like this: the method that the dry returning charge of a kind of glyphosate technicals is reclaimed, the glyphosate technicals wet-milling enters to enter after the main drying tower drying through feed appliance again and revolves the trip drying tower, after cyclone drying tower drying, obtain qualified glyphosate technicals, it is characterized in that: the material that goes out the cyclone drying tower enters cyclone separator, and is dry after reentering main drying tower and glyphosate technicals wet-milling in the main drying tower mixes under the effect of blower fan by the isolated powder of cyclone separator.The pressure of cyclone separator is controlled at-2.5 ~-1.5KPa.
The method that the dry returning charge of glyphosate technicals provided by the invention is reclaimed, adopt high pressure positive blower and stainless steel airduct with the powder of low content, high high-grade-goods rate, be returned in the main drying tower and carry out combination drying with wet-milling, it is dispersed in the glyphosate technicals packs, the high-grade-goods rate of having realized glyphosate technicals improves 2%, and the former medicine rate of recovery reaches more than 99.9%, has greatly reduced the generation of powder, optimize production environment, the steam equal loss falls 20% on a year-on-year basis.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is process chart of the present invention.
The specific embodiment
Embodiment 1:
The heat of main drying tower from vapor heat exchanger, blast in the main drying tower by air blast, the glyphosate wet-milling of being sent into by feed appliance is carried out drying, the glyphosate wet-milling is kicked up by hot whirlwind in main drying tower and is blown in the cyclone drying tower, blowing namely gets qualified glyphosate technicals at the bottom of the cyclone drying Tata, and the hot whirlwind of cat head is drawn in the cyclone separator with the glyphosate powder of low content, high high-grade-goods rate.Glyphosate powder in the cyclone separator is sent in the main drying tower by blower fan, again carries out combination drying with the glyphosate wet-milling, and reciprocation cycle reclaims, to improve the former medicine rate of recovery.The pressure of cyclone separator is controlled at-2.5 ~-1.5KPa, blowing namely gets the glyphosate powder at the bottom of the cyclone separator tower, the hot whirlwind of cat head is brought into the glyphosate dust of minute quantity and carries out filtered and recycled in the sack cleaner, then enters emptying after the washing in the foam dust collector.
Claims (2)
1. the method that reclaims of the dry returning charge of a glyphosate technicals, the glyphosate technicals wet-milling enters the cyclone drying tower after entering main drying tower drying through feed appliance again, after cyclone drying tower drying, obtain qualified glyphosate technicals, it is characterized in that: the material that goes out the cyclone drying tower enters cyclone separator, and is dry after reentering main drying tower and glyphosate technicals wet-milling in the main drying tower mixes under the effect of blower fan by the isolated powder of cyclone separator.
2. the method that reclaims of the dry returning charge of glyphosate technicals according to claim 1 is characterized in that: the pressure of cyclone separator is controlled at-2.5 ~-1.5KPa.
