Modular solar heat collection and sea water desalination driving system and operation method

Abstract

The invention discloses a solar heat collecting device, which comprises: a heat absorbing pipe sleeved with a focus positioning ring; a top reflecting surface arranged above the heat absorbing pipe; aparabolic reflecting surface arranged below the heat absorbing pipe; and a connecting bracket, wherein the focus positioning ring, the top reflecting surface and the parabola reflecting surface are connected together through the connecting bracket, and the straight line where the focus of the parabola reflecting surface is located is consistent with the center line of the heat absorbing pipe. Theinvention further discloses a modular solar heat collection device, a modular solar heat collection and seawater desalination driving system and an operation method of the modular solar heat collection and seawater desalination driving system. According to the modular solar heat collection device, modularization of the solar heat collection device is achieved, the number and the arrangement modeof the solar heat collecting device can be flexibly arranged according to the power requirement and the actual site situation, large-area collection of solar energy is achieved, and the seawater desalination yield is increased.

Description

technical field [0001] The invention relates to a solar seawater desalination system, in particular to a solar heat collection device, a modularized solar heat collection device, a system and an operation method for modularized solar heat collection and driving seawater desalination. Background technique [0002] Seawater desalination technology is the technology of obtaining freshwater by separating the freshwater components in seawater and concentrating seawater. With the development of international trade, the economy of coastal areas around the world has developed rapidly, and large cities with high population density have emerged continuously, accompanied by a huge demand for fresh water resources. Due to the huge demand, most coastal cities cannot meet their long-term and stable demand for fresh water resources through remote water transfer or groundwater pumping. Therefore, obtaining fresh water resources from rivers and seawater has become a truly feasible solution. ...

AI Technical Summary

Problems solved by technology

[0004] However, the current solar desalination technology has the following shortcomings: 1. The output is small and cannot meet the fresh water needs of a large population; 2. The structure is complex, and the initial investment cost corresponding to the output of fresh water per ton is high, which cannot meet the economic requirements, so it is not available. Conditions for large-scale application; 3. The reliability of the equipment is poor, and it is difficult to ensure long-term stable operation
