Problems solved by technology

But it at least has the following defects. When ice crystals are added to the ice crystal drain net for centrifugation, because the ice crystals are piled up in the ice crystal drain net, the phenomenon of ice crystal accumulation and bonding is prone to occur, resulting in the inability to effectively separate the salt content on the surface of the ice crystals and in the gaps between the ice crystals; in addition, its Fresh water is used to wash ice crystals. On the one hand, fresh water needs to be consumed in the process of seawater desalination. On the other hand, the melting of ice crystals will be accelerated in the process of fresh water spray washing. out reduction

Embodiment 1

[0054] In the traditional scheme, when the ice crystals are crushed to a certain size and then added to the inner drum 4 for centrifugation, if the amount of material added is too small, the efficiency will be too low; , resulting in a large amount of salt attached to the ice crystals and the salt in the gaps of the ice crystals cannot be effectively separated from the ice crystals under the action of centrifugation, which will significantly deteriorate the desalination effect. In this embodiment, by setting the ice crystal dispersing mechanism 6, the ice crystals added to the inner drum 4 can be effectively dispersed to reduce the accumulation of ice crystals and the phenomenon of mutual adhesion, and promote the separation of salt and ice crystals; further, by purging Mechanism 7 provides high-pressure gas to purge the ice crystals, so that the salt adhered to the ice crystals can be separated from the ice crystals smoothly, and the salt in the gap between the ice crystals ca...

Embodiment 2

[0076] refer to Figure 9-10 The locking assembly 8 includes a locking seat 80 affixed to the sealing cover 43, a sliding sleeve 81 affixed to the locking seat 80, a locking pin 82 movably inserted in the sliding sleeve 81, and a vertically connected On the locking pin 82 and out of the driving rod 83 of the sliding sleeve 81, the chute 84 provided on the sliding sleeve 81 in the axial direction for the sliding of the driving rod 83 and connected between the inner end of the driving rod 83 and the sliding sleeve 81 The compression spring 85;

[0077] A U-shaped bolt 30 is arranged on the outer drum 3 , and the outer end of the driving rod 83 can be inserted into the U-shaped bolt 30 so as to realize the locking between the sealing cover 43 and the outer drum 3 .

[0078]The working principle of the locking assembly 8 is: the compression spring 85 produces an outward thrust on the locking pin 82, so that the locking pin 82 will slide outwards to the limit position relative to ...

Embodiment 3

[0080] refer to Figure 11 The outer wall of the mounting post 60 is also provided with some second jet holes 68 communicating with the air passage 62, the second jet holes 68 are tapered, and the diameter of the gas outlet of the second jet holes 68 is smaller than the diameter of the air inlet. The setting of the second jet hole 68 can further improve the blowing effect on the ice crystals, which is beneficial to the separation of salt and ice crystals.

[0081] In one embodiment, the working process of the centrifugal device for seawater desalination is:

[0082] 1. Add ice crystals: the external pipeline for supplying compressed air is removed from the air inlet pipe 70, and the outer protective cover 20 is opened by rotating the handle 24, and the air inlet pipe 70 is removed from the rotary joint 71 (or not removed) , open the locking assembly 8, then rotate the sealing cover 43, so that the sealing cover 43 is separated from the mounting column 60 to open, and then the...

Abstract

The invention discloses centrifugal equipment for sea water desalination. The centrifugal equipment comprises a support, a shell arranged on the support, an outer rotary drum rotatably arranged in theshell, an inner rotary drum arranged in the outer rotary drum and capable of rotating along with the outer rotary drum, a driving mechanism used for driving the outer rotary drum to rotate, an ice crystal dispersing mechanism arranged in the inner rotary drum and a purging mechanism, wherein the ice crystal dispersing mechanism comprises a mounting column and a plurality of trays, the mounting column is connected with the bottom of the inner rotary drum and is internally provided with an air conveying channel, the trays sleeve the hollow mounting column at intervals along a vertical direction, and a plurality of first air spraying holes communicating with the air conveying channel are formed in the upper surfaces of the trays; and the purging mechanism is used for inputting compressed airinto the air conveying channel so as to purge the ice crystals in the inner rotary drum. According to the centrifugal equipment for seawater desalination, separated salt can be rapidly separated fromice crystals by utilizing the dual effects of centrifugal force and compressed air purging, and the salt in seawater is greatly reduced, so seawater desalination is realized.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a centrifugal device for seawater desalination. Background technique [0002] Fresh water is an important resource for life and production. With the changes in the world environment, the increase of population, the improvement of living standards and the rapid development of industry, the demand for water resources is getting higher and higher. In today's world, the shortage of fresh water resources has become a global issue. sex issue. Seawater desalination technology started in the 1950s. Seawater desalination technology has developed into a reliable industrial technology that can alleviate the shortage of fresh water resources. According to the separation process, seawater desalination methods mainly include distillation method, membrane method, crystallization method, ion exchange method, etc. Among them, the crystallization method mainly includes freezing me...
