Embodiment Construction

[0028] In one of the specific embodiments of the present invention, a heat storage block is provided, which is prepared by compression molding of a heat storage material, and the overall appearance is spherical or quasi-spherical, wherein the heat storage material is at least made of industrial slag and solidified binder , The specific heat enhancer and the heat storage enhancer are uniformly mixed and then prepared; among them, the heat storage enhancer is a phase change material.

[0029] Among them, the quasi-spherical shape refers to a shape similar to a sphere, such as an ellipsoid shape, an egg-like shape, or a lentil-like shape, including but not limited to a regular or irregular shape with a spherical surface on the body.

[0030] Among them, industrial slag includes boiler coal slag from power plants or thermal power companies, and smelting slag. Its main composition is mainly oxides (silica, alumina, calcium oxide, magnesium oxide), and often contains sulfides and contains...

Abstract

The invention provides a heat storage block, a preparation method thereof and a heat storage greenhouse, which belong to the technical field of agricultural facilities and equipment. The heat storageblock is mixed by industrial slag, solidified binder, specific heat enhancer and heat storage enhancer, and then molded into a spherical or sphericity-like block. On the one hand, a large amount of industrial slag is recycled, which effectively reduces the cost of heat storage and the cost of solid waste disposal. On the other hand, the heat storage block is used as a heat storage material, and israndomly filled in the heat storage wall and / or frame of the greenhouse; the adjacent heat storage blocks are difficult to completely fit together, so that a large number of irregularly distributed channels are formed, which greatly increases the heat exchange area; when the temperature in the greenhouse increases, the heat storage block quickly absorbs the heat in the greenhouse and uses the heat storage principle of a phase change material to store the heat in the heat storage block; and when the temperature in the greenhouse decreases, the heat stored in the heat storage block is releasedto regulate the temperature in the greenhouse.

Description

Technical field [0001] The invention belongs to the technical field of agricultural facilities and equipment, and specifically relates to a heat storage block, a preparation method thereof and a heat storage greenhouse. Background technique [0002] With the development of my country's economy and the adjustment of rural planting industry structure, greenhouse cultivation has developed rapidly. The use of greenhouses for the cultivation of vegetables and other crops improves the economic benefits of vegetable farmers, while the social benefits are also very significant. The solar greenhouse is a unique type of greenhouse in northern my country. In the cold winter, when the sun is full during the day, the heat storage north wall absorbs excess indoor heat, and when the temperature drops at night, the heat storage north wall releases the absorbed heat to maintain The indoor temperature is at a certain value to meet the needs of crop growth in the greenhouse. [0003] Generally, the ...
