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

The invention belongs to the technical field of chemical equipment, and in particular relates to a filter for removing trace moisture in organic solvents. It consists of a feed pipe, a discharge pipe, a shell, a liquid-solid separation area, an oil-water separation area, and a sedimentation separation area. The solid waste hopper is composed of a waste slag hopper and a waste slag discharge pipe. The solid waste slag hopper structure is located under multiple vertical partitions; the oil-water separation area is composed of a perforated fixed plate, a perforated partition, a filter tube, and a fixed plate. The perforated fixed plate and the fixed plate are respectively The body axis is set in a direction perpendicular to the body axis, and the two ends of the filter tube are respectively connected to the perforated fixing plate and the fixing plate; the sedimentation separation area is composed of a control liquid level gauge, an outlet pipe, and a water storage tank. The tank is located at the bottom of the housing and is connected to the outlet pipe. The invention prolongs the service life of the filter tube, improves the water removal effect, realizes real-time monitoring of the oil-water separation interface and automatic drainage through the setting of pre-filtration, filter tube, separator and control liquid level gauge.

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...
