Multi-stage freezing automatic water purifier and multi-stage freezing water purification method using same

Abstract

The invention provides a multi-stage freezing automatic water purifier and a multi-stage freezing water purification method using the same. The multi-stage freezing automatic water purifier comprises a freezing module and a melting module, wherein the freezing module comprises a plurality of freezing pools which are sequentially arranged in a stacked mode from top to bottom; the melting module comprises a plurality of melting pools which are arranged in one-to-one correspondence with the freezing pools; an ultrasonic vibrator is arranged in each melting pool, and an ultrasonic probe is connected to the ultrasonic vibrator; the freezing module and the melting module conduct heat exchange through a refrigerating unit; the freezing module, the melting module, the ultrasonic vibrators, the ultrasonic probes and the refrigerating unit are all connected with a controller and controlled by the controller; and wastewater to be treated is subjected to multi-stage freezing and melting between the freezing module and the melting module. The invention aims to provide the multi-stage freezing automatic water purifier which is simple to operate, wide in application range, small in occupied area, low in energy consumption and capable of carrying out indifference purification treatment on wastewater with different water qualities and the multi-stage freezing water purification method using the multi-stage freezing automatic water purifier.

Description

technical field [0001] The invention relates to multi-stage treatment of water, waste water or sewage, in particular to a multi-stage freezing automatic water purifier and a multi-stage freezing water purifying method using the same. Background technique [0002] With the development of the economy, people's living standards have gradually improved. On the one hand, with the continuous advancement of industrialization, the problem of environmental pollution is becoming more and more serious, especially the water environment is still deteriorating; on the other hand, with the upgrading of consumption and the improvement of the quality of life, people pay more and more attention to health and health. Water quality requirements are getting higher and higher, so water purifiers have become an indispensable household appliance for many families, and the demand for water purifiers market has also increased. [0003] Existing household terminal water purification appliances includ...

AI Technical Summary

Problems solved by technology

[0003] Existing household terminal water purification appliances include activated carbon, multi-functional membrane filtration, disinfection and other products, but their improper use may cause secondary pollution of water quality and a large amount of water waste. In addition, the actual functions and functions of these terminal water purification appliances often Exaggerated or misunderstood, disguised as exacerbating concerns about the safety of drinking water in cities and towns

[0004] Now common water treatment devices mainly adopt membrane treatment method and ion exchange method. These methods have some defects. The defects of ultrafiltration membrane treatment method are that they cannot remove heavy metals, the quality of membrane is uneven, there are problems such as concentrated water discharge and environmental protection. , and the treated water lacks minerals and trace elements, which is not beneficial to human health

In addition, the common water purification device has a complex structure and high cost, which is not conducive to large-scale promotion for ordinary families. Drying, which leads to a sharp drop in water production and cannot be recovered. With the extension of the use time of the water purification product filter element, impurities in the water will block the filter element, and the activated carbon filter element will be adsorbed and saturated. It needs to be replaced regularly, which is inconvenient and expensive to use. If it is not replaced for a long time, it is easy to breed bacteria, which will have an adverse effect on the disinfection and purification effect.
