Problems solved by technology

The traditional coalescer uses the special fiber of the filter element to absorb and coalesce the moisture contained in the organic solvent to remove free and emulsified water in the organic solvent, but in practical applications, the filter element is easily blocked by solid impurities in the organic solvent , and the filter medium material of the filter element is not in full contact with the feed liquid, the utilization is not sufficient, the service life of the filter element is short and the price is high, and the cost is relatively high in practical applications
Pervaporation membrane technology is a new separation technology that can effectively remove trace moisture in organic solvents with low energy consumption. However, the key to the practical application of pervaporation membrane modules is to prepare composite membranes with excellent performance suitable for specific systems. The cost is high, and this component does not have the function of filtering solid impurities in organic solvents. In practical applications, preset filters are required, which increases the processing cost

Abstract

It relates to the micro quantity moisture filter of an organic solvent in the field of chemical equipment. It is made of the feeding pipe, outgoing pipe, shell, liquid and solid separating zone, oil water separating zone, and depositing separation zone, with the liquid and solid separation zone at one side of the opening inside the shell made by several blocks of barricades offset in equal distance, solid slag bucket under the multi blocks of barricade and slag exhaust pipe, oil water separation zone made of through hole fixing plate, through hole barricade, filter element pipe, fixing plate, with the through hole fixing plate and fixing plate along the line perpendicular to the axle of the shaft, both ends of filter elements connecting with through hole fixing plates and fixing plates, depositing separation zone made of liquid lever control at one side of the shell, water outlet pipe, water reserving tank at the bottom of the shell and connecting with water outlet pipes. Through the above structure, it can extend the life of the filter element pipe, improving dewaters effect, realizing time control of the oil water partition line with automatic exhaust of water.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and in particular relates to a filter for removing trace moisture in organic solvents. Background technique [0002] Organic solvents such as alcohols, esters, ethers, ketones, aromatic compounds, chlorinated hydrocarbons, oils, etc. inevitably introduce or generate water in the production and application process, which brings great difficulties to the separation, purification and recovery of solvents. It's an inconvenience. [0003] Existing equipment for removing trace moisture in organic solvents includes coalescers and pervaporation membrane filter components based on the new membrane separation technology steam permeation method. The traditional coalescer uses the special fiber of the filter element to absorb and coalesce the moisture contained in the organic solvent to remove free and emulsified water in the organic solvent, but in practical applications, the filter element is e...
