Problems solved by technology

Determined by the evaporation principle of the thin-film evaporator, the liquid level height of the heating tube entering the evaporation interlayer of the thin-film evaporator is limited, otherwise it cannot be effectively heated in the evaporation interlayer of the thin-film evaporator The liquid film is formed on the tube wall, which easily destroys the controllability of the water in the liquid film and destroys the stability of the entire evaporation system. Moreover, so far, there is no reliable automatic flow control The device technology can achieve the purpose of stably controlling the flow of liquid medicine under complex and changeable conditions
Moreover, the deflector on the main body is fixed and difficult to clean

Abstract

The invention relates to a film type evaporator with film climbing, film falling and separating functions, which is characterized by comprising a barrel-shaped evaporator main body with an interlayer on the lateral wall, a steam suction tube which is connected with a vacuum suction device and penetrates into the inner cavity of the barrel-shaped evaporator main body, a heating tube with an upper port communicated with the inner cavity of the barrel-shaped evaporator main body and a lower port communicated with a liquor inlet positioned in the interlayer, a liquor delivery device communicated with the liquor inlet, and a liquid level control device positioned on the delivery tube of the liquor delivery device; the interlayer is communicated with a high-temperature steam delivery port; a condensed water discharge device is arranged at the lower end of the interlayer; a concentrated liquor outlet is arranged at the lower end of the inner cavity of the barrel-shaped evaporator main body; the liquor delivery device comprises a liquor barrel, a liquor supply pump and the delivery tube; and the liquor outlet under the liquor barrel is communicated with the liquor inlet through the liquorsupply pump and the delivery tube. Compared with the prior art, the invention has the advantages that a stable and controllable evaporating system is ensured, and the heat energy can be utilized fully.

Description

Technical field: [0001] The invention relates to a thin film evaporator. Background technique: [0002] An existing thin-film evaporator, as disclosed in patent 99245615.0, the flow rate of the liquid medicine entering the thin-film evaporator is controlled by an automatic flow control device, and the pressure of the steam is used to switch and activate the flow rate to control the liquid medicine flow rate. When the steam pressure is high, the flow rate of the liquid medicine is large, and when the steam pharmacology provided is small, the flow rate of the liquid medicine is small. Determined by the evaporation principle of the thin-film evaporator, the liquid level height of the heating tube entering the evaporation interlayer of the thin-film evaporator is limited, otherwise it cannot be effectively heated in the evaporation interlayer of the thin-film evaporator The liquid film is formed on the tube wall, which easily destroys the controllability of the water in the liq...
