Background
The rectification is to gasify light components with lower boiling points or higher saturated vapor pressure by utilizing different boiling points or saturated vapor pressures of all components of a liquid mixture under certain pressure, and gradually increase the concentrations of the light components in a gas phase and heavy components in a liquid phase by utilizing reflux to gasify part of the liquid phase and condense part of the gas phase for many times, thereby achieving the purposes of separation and purification.
The main equipment for rectification comprises: a rectifying tower, a reboiler, a condenser, reflux conveying equipment and the like. After the liquid mixture feed liquid enters the rectifying tower, the light components are gradually concentrated towards the tower top, and are condensed in a condenser after leaving the tower top, one part of the light components are used as light component finished products, and the other part of the light components are sent into the rectifying tower to be used as reflux liquid, so that the continuous and stable operation of the rectification is ensured. The heavy components are gradually concentrated towards the bottom of the tower, one part of the heavy components are used as finished products of the heavy components, and the other part of the heavy components are heated and evaporated by a reboiler and are sent back to the rectifying tower, so that enough continuously rising steam flow is provided for the rectifying operation. Typical rectifying towers include a plate tower, a packed tower and the like, have mature theories and equipment, and are widely used in the industries of petroleum, chemical engineering, light industry, food, metallurgy and the like. However, the distillation process implemented by the distillation column in the prior art needs to consume a large amount of energy during evaporation and reflux, and has the defect of high cost.
The rectifying head is an important component in rectifying equipment, the quality of rectification directly influences the whole rectifying process, one of the two existing glass rectifying heads with the automatic control reflux ratio is in a rotary type, and an O-shaped ring at a sealing part is easily corroded by a solvent or a corrosive material to cause leakage; one is swing type, the reflux ratio is controlled by the swing position of the triangular funnel with the magnet, the coil is electrified to generate magnetic force, the triangular funnel with the magnet can knock the outer layer glass when being sucked, and the glass is easy to break; the reflux amount of the two glass rectification heads cannot be too large, and the triangular funnel cannot be too large due to limited magnetic force, so that the reflux amount is influenced, and the rectification device with the volume of more than 50L cannot be met.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to solve the defects of the prior art, the utility model provides a glass rectification head with an automatic control reflux ratio.
