Embodiment Construction

[0023] In order to describe the technical content of the present invention more clearly, the detailed working process of the device from feed water to distilled water is given below. The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] The invention provides a solar distillation device with interface heating, the working process of the device is:

[0025] The water pump extracts raw material water after rough treatment, and the raw material water is stored in the overflow water storage tank 4) through the water inlet pipe 1) and the water inlet 2). During this process, the electric energy required for the water pump to work is provided by the photovoltaic panel 8 . The area of ​​the photovoltaic panel 8 is obtained by calculation, and it is required to have a solar radiation intensity of 1000W / m 2 The generated power under the pump should be greater than the rated power of the pump.

Abstract

The invention discloses a solar distillation device with an interface heating function. The solar distillation device comprises an overflow water storage tank, a double-layer glass cover plate, a photovoltaic panel, a water collecting tank, a solar absorbing material, a thermal insulation material, a hydrophilic material, an evaporation tank body and a pipeline part. The device can achieve the function that water is heated and evaporated on an interface; the heat loss of heat energy converted from solar energy to the environment can be reduced in virtue of a thermal insulation design; latent heat released by water vapor condensation and waste heat generated by photovoltaic power generation can be recycled at the same time through cooling of the glass plate; and the fresh water yield per unit area and the solar energy utilization rate of the device are greatly improved compared with a traditional passive solar distiller.

Description

technical field [0001] The invention belongs to the technical field of solar seawater desalination, and more specifically relates to a solar distillation device with interface heating. Background technique [0002] Conventional seawater desalination methods mainly fall into the following categories: distillation, reverse osmosis, dialysis, multi-effect distillation, and multi-stage flash evaporation, etc., but these methods require conventional energy to drive the system to generate fresh water. Compared with conventional energy sources, solar energy resources have the advantages of being inexhaustible, clean and safe. A solar still is a device that uses solar energy to distill seawater or brackish water to obtain fresh water. The traditional solar still has a very simple structure, mainly consisting of a pool filled with raw water with a blackened bottom and a glass cover covering it. The lower part of the glass cover plate is provided with a water collecting tank, which ...
