The invention discloses a non-shrink concrete, and belongs to the technical field of building concrete. The non-shrink concrete is prepared from sulphate aluminum cement, medium sand, flyash, methylcellulose, aluminum nitride powder and an expanding agent. The non-shrink concrete has the beneficial effects that sodium gluconate and sodium citrate are added to the expanding agent, so that concrete condensation can be slowly retarded; methylcellulose is added to the concrete, so that water can be slowly released, the hydration reaction rate is reduced and the heat generation speed is reduced; the aluminum nitride powder or quartz powder is added to the concrete, so that heat release can be accelerated; the methylcellulose and aluminum nitride are cooled and heated synergistically, the expanding rate is improved and shrinkage is automatically reduced to achieve the non-shrink target.

The invention discloses an automatic steam flow adjusting device for geothermal energy power generation. The device comprises a heat preservation steam cover, a communicating port is formed in the upper end of the heat preservation steam cover, a steam circulating pipe is connected to the communicating port in a sealed mode, an inverted-T-shaped block is connected to the inner wall of the upper end of the heat preservation steam cover through two lifting mechanisms, a buoyancy ball is fixedly connected to the side wall of the upper end of the inverted-T-shaped block, a conical cover is fixedlyconnected to the inner wall of the upper end of the heat preservation steam cover, and a plurality of fixing rods are fixedly connected to the inner wall of the conical cover. According to the device, a gap between the buoyancy ball and the conical cover can be automatically adjusted according to the water temperature and the steam amount, and then the steam flow is adjusted; the structure is simple, the flow adjusting effect is remarkably improved, the economic cost is low, and the installation is convenient; then the power stability of a steam generator during power generation is guaranteed, and therefore the safety of parts of the steam generator is protected, and the service life of the steam generator is long; and meanwhile, the energy consumption is guaranteed, and the utilization rate of geothermal energy is increased.

The present invention discloses a compound feed for growing and fattening pigs for reducing ammonia gas emission and a preparation method thereof. The feed comprises 55-75 parts by weight of corn, 5-15 parts by weight of fermented soybean meal, 8-15 parts by weight of rice bran meal, 0-3 parts by weight of soybean oil, 0-8 parts by weight of flour, 3-10 parts by weight of corn distillers dried grains with soluble (DDGS), 0.5-1.5 parts by weight of stone powder, 0.5-1.5 parts by weight of bentonite, 0.3-0.8 part by weight of calcium hydrogen phosphate, 2.0-2.5 parts by weight of a premix for finishing pig growing and fattening pigs and 0.06 part by weight of a plant composition premix agent. The plant composition premix agent comprises a lauraceae plant extract, a yucca plant extract and tea leaf residues. On a basis of studying production source of ammonia gas in growing and fattening pig houses, the compound feed fully satisfies the growth and nutrition needs of the growing and fattening pigs. A low-protein daily diet preparation technology is used; and the plant extract premix agent is added, thereby effectively reducing the ammonia gas emission, improving the environment of thehouses, and reducing breeding losses.
