Problems solved by technology

Literature and patent searches show that although the existing technologies or patents are feasible in principle, most of them are very inefficient. In order to improve the overall efficiency of the device, a large number of equipment have to be used, which makes the system too complicated
This is also an important reason why solar desalination devices are difficult to commercialize

Abstract

The invention relates to an integrated solar sea water desalinating device which is provided with a water heating tank and a vacuum pipe, wherein an air collector header is arranged at the internal upper part of the water heating tank; a fresh water tank fixed to a support is arranged under the water heating tank; a side part of the water heating tank is connected to a water replenishing tank; the water heating tank is communicated with the water replenishing tank; and a part of the vacuum pipe is inserted into the water heating tank to heat sea water, while the other part of the vacuum pipe is inserted into the air collector header to heat air. The device is further provided with a fan, wherein the air outlet pipe of the fan is connected to an aerator pipe which is located within the water heating tank; a high-temperature wet air delivery pipe connected with a condensing coil is connected to the water heating tank; the condensing coil is connected to a condenser; and a cold sea waterinput pipeline, a sea water output pipe, an exhaust pipeline and a fresh water discharge pipeline are connected to the condenser. The integrated solar sea water desalinating device is simple and compact in structure, high in efficiency and convenient for commercialization; and the device can be used not only for islands, fishing boats and the like to desalinate sea water, but also for families inwater-deficient areas to treat brackish water and domestic sewage.

Description

technical field [0001] The invention relates to a seawater desalination device, in particular to an integrated solar seawater desalination device which uses solar energy as a heat source and utilizes the principle of air humidification and dehumidification. Background technique [0002] With the depletion of fresh water resources, the shortage of water resources has become a major problem facing mankind in the 21st century. As one of the 13 water-scarce countries in the world, the situation of desalination resources in my country is not optimistic. The development of seawater desalination industry is an important strategic way to solve the shortage of fresh water resources in our country. At present, seawater desalination technologies include freezing method, multi-stage flash evaporation, reverse osmosis technology, etc. Among them, the most widely used multi-stage flash evaporation and reverse osmosis technology. However, the above technologies need to be at the cost of...
