Multilayer cylindrical spiral pipe solar storage tank

Abstract

The invention relates to a multilayer cylindrical spiral pipe solar storage tank. A tank body of the multilayer cylindrical spiral pipe solar storage tank is cylindrical, three cylindrical spiral heat transfer pipeline layers are arranged on the tank body from inside to outside, namely, an outer cylindrical spiral heat transfer pipeline layer, a middle cylindrical spiral heat transfer pipeline layer and an inner cylindrical spiral heat transfer pipeline layer, and each cylindrical spiral heat transfer pipeline layer penetrates in the tank body from top to bottom. A fluid inlet pipe is divided into three inlet branch pipes, each branch pipe is provided with an adjusting valve, and the three inlet branch pipes are connected with inlets of the cylindrical spiral heat transfer pipeline layers respectively and are in one-to-one correspondence with the inlets. Outlets of the three cylindrical spiral heat transfer pipeline layers are gathered to an outlet manifold at the bottom of the tank body, and the outlet manifold extends out of the tank body. A heat preservation layer is arranged on the outer wall of the tank body. By means of the multilayer spiral pipe distribution structure, the heat transfer efficiency of a system is improved, the heat transfer time of the system is shortened, and energy saving of the system is achieved.

Description

technical field [0001] The invention relates to the field of solar thermal power generation, in particular to a multilayer cylindrical spiral tube solar storage tank. Background technique [0002] Solar energy is an inexhaustible source of energy that is non-polluting and environmentally friendly. Therefore, efficient development and utilization of solar energy can achieve extremely high social and economic benefits. However, the energy flow density of solar energy is not uniform, and it will be affected by clouds, rain, wind and sand, etc., and the large-scale application of solar energy has certain technical bottlenecks. At present, solar energy has been well applied in construction, agriculture and civil use, but the efficiency is generally low, usually about 10%. [0003] In order to efficiently utilize solar energy, photothermal power conversion is considered to be a key technical means for industrial utilization of solar energy and to solve the problem of high energy ...
