Distillation type water purification device and water purification method

Abstract

The invention relates to the technical field of distillation type water purifying devices, particularly to a distillation type water purifying device and a water purifying method. The distillation type water purifying device comprises a heating box, a distillation box and a water collecting box, wherein a plurality of heating rods are evenly installed in the heating box, the distillation box is located in the heating box, the bottom side of the right end of the heating box is connected with a mud discharging pipe communicated with the interior of the distillation box, a mud suction pump is installed on the mud discharging pipe, the right end of the distillation box is located above the heating box and connected with a water adding pipe, and the right side of the interior of the distillation box is fixedly connected with a first liquid level sensor and a second liquid level sensor. According to the invention, steam after sewage distillation can be cooled twice, so that the cooling effect is improved, the sewage distillation and purification efficiency is improved, heat can be reutilized, the time of heating sewage in the distillation box by heating rods is reduced, the distillationrate is improved, the distillation and purification efficiency is improved, energy is saved, energy is fully utilized, and the use practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of distillation water purification devices, in particular to a distillation type water purification device and a water purification method. Background technique [0002] With the shortage of potable water resources, seawater desalination and sewage purification technology are increasingly valued by countries all over the world. At present, seawater desalination and sewage purification technology has become a key technology for countries to solve the problem of shortage of potable water resources. Seawater desalination is the process of separating the salt and water in seawater to obtain fresh water and concentrated brine. Sewage purification is the process of separating sediment, waste residues and heavy metals or radioactive substances harmful to health (such as the radiation polluted seawater produced by the Fukushima nuclear power plant in Japan due to the tsunami) from water and finally obtaining purifie...

AI Technical Summary

Problems solved by technology

[0004] The following defects still exist in the above-mentioned prior art scheme: it can collect more sunlight through the Fresnel lens group, and the water is heated and distilled. Normally, the clean water storage steel pot and the ceramic tray are set in the same space, the internal temperature is high, and the effect of cooling the water vapor after sewage distillation is poor, which reduces the efficiency of purifying sewage and reduces the practicality of its use. sex
