Problems solved by technology
The general defect of this process is that the requirements for the semi-permeable membrane used are relatively high, which leads to high cost. In addition, the performance of the semi-permeable membrane is limited, and the processing capacity of membrane separation is generally small.
[0009] Therefore, how to use the existing cyclone separator with reliable performance and large processing capacity to process and separate the miscible substances is a technical problem faced by this field.

Embodiment 1
[0034] use figure 2 As shown in the cyclone separator of the present invention, its raw materials and operating conditions are the same as those of the comparative example. After a period of stable operation, it is tested that, typically, the salt content of seawater obtained from outlet b is 43.4‰, and the salt content of liquid obtained from outlet a is 1.5‰.
[0035] Comparing the examples of the present invention with the comparative examples, it can be seen that the cyclone separator of the present invention realizes the separation of miscible substances, while the cyclone separator of the prior art cannot separate miscible substances. Unfavorable technical effect.

The invention discloses a cyclone and a cyclone separation method for realizing concentration separation of intersoluble substances by the utilization of cavitation. The cyclone mainly comprises an inlet, a disengagement chamber and two outlets. The two outlets maintain at low pressure (vacuum environment), wherein equipment for realizing low pressure environment for the outlet far from the inlet is preferably a water pump or other suction equipment, and equipment for realizing low pressure environment for the outlet close to the inlet is preferably a low pressure pipeline, a vacuum pump or a water pump. According to the invention, through improvement of a present cyclone, its internal liquid undergoes cavitation, and a large number of generated cavitation bubbles are utilized to realize concentration separation of intersoluble substances.
Description
technical field [0001] The present invention relates to a cyclone separator and a cyclone separation method, in particular to a cyclone separator for realizing solution cavitation and concentration separation and a cyclone separation method for solution cavitation separation, more specifically to a seawater A cyclone separator and separation method for generating dilute brine and concentrated brine through cavitation separation. Background technique [0002] Cyclone separator, also called liquid cyclone separator, has been widely used in many fields due to its small size, simple structure and large processing capacity. Such as figure 1 as shown, figure 1 The cyclone separator 1 shown is the most typical one in the prior art, which mainly includes an inlet 2, a column-cone separation chamber composed of a cylinder 5 and a cone 6, and two outlets 3, 4. There can be one or more entrances 2, but single entrance and double entrance are the most commonly used, and the entrance ...
