Description

The formula and preparation technology of a kind of heat accumulation concrete
Technical field
The present invention relates to the solid heat-storage technology field in a kind of photo-thermal power generation, more particularly to a kind of heat accumulation concrete Formula and preparation technology.
Background technology
Solar light-heat power-generation refers to collect solar thermal energy using large scale array parabolic or dish-shaped minute surface, filled by exchanging heat Offer steam is put, with reference to the technique of traditional steam turbine generator, so as to reach the purpose of generating.Using solar light-heat power-generation skill Art, it is to avoid expensive silicon wafer opto-electronic conversion technique, can substantially reduce the cost of solar power generation.The master of photo-thermal power generation technology It is that the regulation of external electric power output is realized by heat reservoir to want technical advantage, realizes steady electricity supply.
Using inorganic salts as the heat accumulation material in heat reservoir more than current industrialized solar light-heat power-generation unit Material, but inorganic salts have the shortcomings that supercooling and phase separation in phase transition process, have impact on heat storage capacity, and its setting temperature mistake Height, causes night to ensure that it is larger that it does not solidify the exterior line soak cycles heat loss that carries out, once system solidifies Dispose difficult after point, there is potential safety hazard;The pump, the valve that are used in inorganic salts system pipeline are expensive and service life also compares It is short, and inorganic salts have certain toxicity, and easily fire occurs for leakage, leakage can also cause environmental pollution.
The content of the invention
Again can be big it is an object of the invention to provide the thermal storage performance required by a kind of can meet in photo-thermal power generation unit Width reduces the concrete formulation and its manufacture craft of cost.
According to an aspect of the invention, there is provided a kind of formula of heat accumulation concrete, includes the group of following parts by weight Into composition:Cement 10.8~13.6;Silicon powder 0~1.2;Flyash 2.56~2.88;Miberal powder 2.56~2.88;Andalusite powder 0 ~1.2;The stone 32.4~38.8 of 5~10mm size gradings;The middle sand 33.2~39.6 of 0~3mm particle diameters;Water reducer 0.34~ 0.6;Polypropylene fibre 0.072~0.1;Steel wool silk 1.8~2.2;Water 7.2~8.4.
It is preferred that the, the stone of 5~10mm size gradings is one in basalt stone, crushed granite or cobblestone Kind.
Preferably, the middle sand of 0~3mm size gradings is basalt Machine-made Sand, crushed granite Machine-made Sand or goose ovum One kind in stone Machine-made Sand.
Wherein, the apparent density of the heat accumulation concrete when in use is 1900~2300Kg/m3, thermal conductivity factor is 0.9 ~1.5W/ (m*K), specific heat capacity is 0.85~1.10KJ/ (Kg* DEG C).
According to another aspect of the present invention, a kind of preparation technology for making above-mentioned heat accumulation concrete is additionally provided, is wrapped Include following steps:
(1) under normal temperature, by cement, silicon powder, flyash, miberal powder, andalusite powder, the stone of 5~10mm size gradings, 0 Middle sand and the steel wool silk of~3mm particle diameters, which are put into mixer machine, to be stirred 1~3 minute;
(2) polypropylene fibre is broken up, the polypropylene fibre broken up, water reducer is mixed with water;By polypropylene fibre, subtract The mixture of aqua and water, which is put into mixer, to be continued to stir, and stirring can be used after 2~4 minutes.
Heat accumulation concrete in the coefficient correlation of the concrete obtained from above technical scheme, the present invention can expire Requirement of the sufficient photo-thermal power generation unit heat reservoir for thermal storage performance.Because the concrete formulation in the present invention need not add graphite The materials such as powder, metal ore material or steel fibre, therefore cost can be greatly reduced in its formula.The preparation process letter of concrete simultaneously It is single, it is easy to construction, and verified through actual fabrication process, it is rapid that concrete prepares middle and later periods steaming water process safety.
Embodiment
