[0119] Figure 8 A top cross-sectional view of a liquid evaporating device along the axis of rotation is shown according to another embodiment of the present invention.

[0120] relative to binding figure 1 describe the liquid evaporation device, Figure 8 The liquid evaporation device shown is further optimized on the rotor and disk.

[0121] Specifically, the rotating shaft (201) is optimized as a hollow shaft, which is divided into two parts, the water / gas pipeline and the water / gas pipeline under the action of the isolation belt (2013), at both ends of the rotating shaft (201) (not limited to the shaft end) The total heat source inlet (2011) and the heat source total outlet (2012) are respectively set up, and the disk heat source inlet (2021) and the disk heat source outlet (2022) are arranged at the connection part with the disk;

[0122] The disk (202) is also designed as a hollow structure, with a diversion groove (2023) inside, and a disk heat source inlet (2021) and...

Abstract

The invention provides a liquid evaporation device and a liquid evaporation process. The liquid evaporation device comprises a shell and a rotor. The shell is used for accommodating to-be-evaporated liquid. The rotor is mounted in the shell. A liquid inlet and a liquid outlet are arranged on the shell. The rotor comprises a hollow rotating shaft and hollow plates. The outer surfaces of the platescan be wetted by solvents of the to-be-evaporated liquid, and the to-be-evaporated liquid is enabled to form liquid films on the outer surfaces of the plates. The rotating shaft comprises a water / gasinlet pipeline and a water / gas outlet pipeline. A main heat source inlet and a main heat source outlet are arranged on the rotating shaft. Plate heat source inlets and plate heat source outlets are arranged on portions, connected with the plates, of the rotating shaft, and are arranged on portions, connected with the rotating shaft, of the plates. The plates of the evaporation device provide enough specific area for liquid evaporation, and also provide heat transfer area for internal heat sources to have a heat transfer function. By the liquid evaporation device, high efficiency in evaporationcan be realized when liquid is in a non-boiling state.

Description

technical field [0001] The invention generally relates to a liquid evaporation technology, in particular to a liquid evaporation device and process without boiling the liquid, and is mainly used in the fields of chemical industry and water treatment. Background technique [0002] The so-called evaporation refers to heating the mixed liquid to be separated (or taking decompression measures at the same time) to boiling, drawing out the generated steam and condensing to obtain a condensate, and the remaining liquid is a concentrated liquid different from the original mixed liquid. Evaporation to the end achieves the separation of the liquid and the solid matter dissolved in the liquid. The main points of the evaporation process: one is to maintain the temperature and pressure of the material within a certain range, usually to make the material boil continuously or intermittently; the other is to discharge the steam from the evaporator in time so that the vapor pressure in the e...
