Method for constructing ceramic solar hot water energy storage device by drilling holes into bedrock in alluvial soil layer

Abstract

The pile driver drills holes into the bedrock to build ceramic solar energy storage devices, involving solar hot water energy storage devices. The pile driver uses steel pipe piles to drill holes in the accumulated soil layer, and injects high-pressure water or high-pressure mud into the steel pipe piles Reduce the friction force of pile drilling and protect the hole wall. When the drilling depth reaches the bedrock or rock formation, the drilling work stops. Insert a polyethylene pipe and tank combiner into the hole in the accumulation layer with a hole depth of more than 5 meters, and pass through the horizontal, The vertical communication pipe forms the heating energy storage system in the soil accumulation layer, and uses local water in spring, summer and autumn to produce 60℃-100℃ hot water to circulate between the heat preservation water tank and the heating energy storage system in the accumulation soil layer, so that spring, summer and autumn can be obtained The solar energy is converted into energy storage in the soil layer, and the hot water heated by the energy storage in the soil layer is used to heat buildings, greenhouses, and biogas digesters in winter.

Description

[0001] (1) Technical field [0002] This application relates to an energy storage device, in particular to using a pile driver to drill holes in the soil layer until the bedrock, heating the local water with a ceramic solar roof or a ceramic solar water heating system and injecting it into the storage pipeline of the soil layer for inter-season low-temperature energy storage installation. [0003] (2) Background technology [0004] Conventional energy has a certain equal relationship with currency, which can be purchased with currency at any time, and generally does not require inter-season low-temperature energy storage. [0005] In winter, the sun angle is low, the solar radiation intensity is weak, and there are haze in some areas, and the solar radiation intensity is further reduced. Low-temperature energy is rarely needed, and a large amount of low-temperature energy is needed in winter. It is of practical significance to carry out low-temperature energy storage for solar...

[0008] 1. Obtaining solar energy: Traditional solar water heating systems are various vacuum glass tube solar water heating systems and metal plate solar water heating systems, in which the solar absorbing film is a chemical substance coated on the surface of glass and metal at room temperature, and these chemical substances are not formed Stable mineral composition and unstable performance. Under sunlight, the sunlight absorption ratio will gradually decay. The higher the water temperature, the faster the decay. When the water temperature reaches 80°C-100°C, the decay speed of the solar absorbing film is obviously accelerated, and the traditional solar water heating system average The actual service life is less than 10 years; the main materials of traditional solar water heating systems are borosilicate glass and metals such as copper, aluminum, and iron. The melting temperature of borosilicate glass is about 1600°C, and the energy consumption It is also equivalent to or higher than 1600 ℃ smelting energy consumption, high energy consumption in manufacturing, and high production cost in general; due to the fast attenuation speed of traditional solar absorbing films, glass tubes are easy to break, and metal welds are easy to corrode. The use and maintenance of traditional solar water heating systems relatively high cost

The applicant applied for the patent of "Greenhouse Ceramic Solar Heating Heat Storage System" on February 22, 2018. It made horizontal grooves on the ground in the greenhouse with a depth of 1-3 meters and buried them in horizontal pipes. The hot water heated by the heat collection system is stored in the heat preservation water tank and the heating soil, which is used to take out the heat energy in the heat preservation water tank and the soil to heat the greenhouse at night or on a sunny day, which is limited by the existing small trenchers on the market. The pipes in the tank are buried at a depth of 1-3 meters, and the general energy storage period is within 15 days. Interseasonal energy storage cannot be realized. If the tank depth continues to increase, the construction cost is high, and it is difficult to realize economical energy storage and energy use.
