Solution concentrator unit

Abstract

The invention relates to a solution concentrator unit, especially to a solution concentrator unit for producing high concentration solutions or suspensions. The solution concentrator unit comprises a housing, a tube still heater disposed inside the housing, an inlet pipe connected at the top of the tube still heater and an evaporator connected with the bottom of the tube still heater through a concentrate outlet hopper, and is characterized in that a transmission shaft is disposed inside the tube still heater; the transmission shaft is connected with a transmission device which is positioned on the upper portion of the housing; a distributing device and a plurality of scraper plates are disposed inside the tube still heater; the distributing device is arranged at the top of the tube still heater; and the scraper plates are connected to the transmission shaft which is positioned inside the tube still heater. According to the invention, the distributing device and the scraper plates are disposed inside the tube still heater so as to realize uniform blanking; in addition, the tube still heater can tolerate high viscosity materials, materials which are easy to generate crystals and materials which are easy to foul so as to realize stable low temperature evaporation and condensation of solutions.

Description

technical field [0001] The invention relates to a solution concentration unit, in particular to a solution concentration unit for producing high-concentration solution or suspension. Background technique [0002] Evaporation and concentration is a production method commonly used in pharmaceutical and chemical production to obtain high-concentration solutions or suspensions. Commonly used processes are concentration at atmospheric pressure, concentration under reduced pressure or concentration under pressure. Commonly used evaporation and concentration equipment are: kettle-type evaporation concentrator, external heating circulation concentrator, forced external circulation concentrator, single-effect falling film device or rising film evaporation concentrator, double-effect or multi-effect falling film or rising film evaporation Concentrator, wiped film evaporation concentrator. Due to the reasons of equipment or medium, these evaporative concentrators cannot have low-temp...

AI Technical Summary

Problems solved by technology

Due to the reasons of equipment or medium, these evaporative concentrators cannot have low-temperature evaporation and concentration at the same time, are resistant to high-viscosity materials, are resistant to materials that are prone to crystal formation, are resistant to materials that are prone to scaling, and save steam and occupy a small area, etc. features

In the secondary steam of these evaporative concentrators, the mist of the material liquid brought out by the airflow is often brought into the condensed water, so that the condensed water of the secondary steam is polluted by the material, which makes it difficult to reuse the condensed water.
