Ceramic solar heating heat-storing system for greenhouse

Abstract

The invention provides a ceramic solar heating heat-storing system for a greenhouse, and relates to the heating heat-storing system for the greenhouse and a ceramic solar heat-collecting system. Grooves are arranged along the surrounding edges in the ground in the greenhouse, and each groove is filled with a thermal-insulation board to reduce heat loss of soil in the greenhouse; and grooves are arranged in the ground in the greenhouse, and deep-layer and shallow-layer soil heating pipelines are buried. According to the system provided by the invention, a building is newly built or a part of greenhouses are transformed into the building with a one-side slope ceramic solar roof, the building is used for planting mushrooms and the like, hot water produced by the ceramic solar roof in spring,summer and autumn heats soil with a thickness of a plurality of meters to form heat storage, so that the greenhouse can maintain higher ground temperature throughout the year; hot water produced in winter heats surface-layer soil and air of the greenhouse; and the ceramic solar heating heat-storing system for the greenhouse has low construction costs, energy comes from the sun, so that the systemhas no environmental pollution, power of a water pump is very small, running costs are very low, and the greenhouse ground temperature, room temperature, crop yield and quality in spring, summer, autumn and winter are greatly improved.

Description

technical field [0001] The invention relates to a greenhouse heating heat storage system and a ceramic solar heat collection system, in particular to an organic combination of the greenhouse heating heat storage system and the ceramic solar heat collection system. Background technique [0002] Greenhouses are used for the production of vegetables and crops. my country’s greenhouses cover millions of acres, accounting for about 50% of the world. Usually dozens to thousands of greenhouses are planted and operated in patches. Greenhouses mainly use the greenhouse effect of winter sunlight to promote crop growth. Growth, in cloudy days and at night, mainly rely on coal-fired heat preservation to maintain crop life. Due to environmental protection, it is required to cancel coal-burning, while natural gas, electricity, and traditional solar devices are expensive, and traditional solar devices have short service life and frequent maintenance. [0003] Traditional solar collectors ar...

[0002] Greenhouses are used for the production of vegetables and crops. my country’s greenhouses cover millions of acres, accounting for about 50% of the world. Usually dozens to thousands of greenhouses are planted and operated in patches. Greenhouses mainly use the greenhouse effect of winter sunlight to promote crop growth. Growth, in cloudy days and at night, mainly rely on coal-fired heat preservation to maintain crop life. Due to environmental protection, it is required to cancel coal-burning, while natural gas, electricity, and traditional solar installations are expensive, and traditional solar installations have short service life and frequent maintenance.

[0003] Traditional solar collectors are vacuum glass tube solar collectors and metal flat solar collectors. The solar absorbing film is formed by the aggregation of sunlight absorbing material particles at room temperature. The bonding force between particles and between particles and the matrix is ​​at best It is a combination of molecular bonds, low bonding energy, low binding force, easy attenuation of sunlight absorption ratio, frequent maintenance, low theoretical life, short actual service life, and higher cost than conventional energy
