A seawater desalination or sewage purification device

Abstract

A seawater desalination or sewage purification device. A plurality of water-holding pipes (11) are successively arranged at intervals in a condensing and preheating chamber (10) of the device; the top of each water-holding pipe (11) is designed to be open, and each water-holding pipe (11) is in communication with each of the other pipes at the bottom so as to form a communicating vessel, two ends of the communicating vessel being connected to a preheating water tank (30) and a heating chamber (20) through water pipes (I, II), respectively; the condensing and preheating chamber (10) is also connected with a condensed water discharging pipe (70), a part of which being placed within the preheating water tank (30), and connected with the heating chamber (20) through a steam pipeline (22); raw water is introduced into the preheating water tank (30) through a water-feeding pipe (31); a heat source device (21) is arranged in the heating chamber (20); and sewage draining exits (32, 23) are arranged in both the preheating water tank (30) and the heating chamber (20). The device has a low energy consumption during distillation and a good purifying effect, and can achieve the effect of immediately drinkable water.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a water treatment device using distillation technology. The water treatment device is especially suitable for seawater desalination and sewage purification. Background technique [0002] Existing seawater desalination and sewage purification treatment technologies cannot be widely used due to high processing costs, and the produced water is basically not directly drinkable. For example, by simple distillation, it takes about 100 kilocalories per kilogram of water to heat up from 0°C to 100°C, and about 600 kilocalories per kilogram of water at 100°C to convert it into steam at 100°C. One kilogram of water consumes about 700 kcal of energy, which is a large energy consumption, and the heat of vaporization of water cannot be recycled, and it is difficult to utilize solar energy. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invent...
