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

Abstract

The pile driver drills holes in the accumulated soil layer to build ceramic solar hot water 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 into the steel pipe piles Or high-pressure mud to reduce the friction force of the punching pile and protect the hole wall. The drilling depth is 30 meters. When the rock layer is encountered halfway, the drilling work stops. Insert polyethylene into the hole in the accumulation layer with a depth of 5 meters to 30 meters. The tube-tank combiner forms a heating energy storage system in the accumulation layer through horizontal connecting pipes. The water capacity of the ceramic solar roof and the ceramic solar hot water system insulation water tank is the number of square meters of ceramic solar panels × 30 liters, using local water in spring, summer and autumn The hot water produced at 60°C-100°C is circulated in the heat preservation water tank and the heating energy storage system in the soil layer, so that the solar energy obtained in spring, summer and autumn is converted into energy storage in the soil layer, and the energy storage in the soil layer is used in winter Heated hot water can be used to heat buildings, greenhouses, and biogas digesters.

Description

[0001] (1) Technical field [0002] This application relates to an energy storage device, in particular to a device that uses a pile driver to drill holes in the soil layer, and uses a ceramic solar roof or a ceramic solar hot water system to heat local water and inject it into the soil layer for inter-seasonal low-temperature energy storage. [0003] (2) Background technology [0004] Conventional energy has a certain equivalence relationship with currency, and can be purchased with currency at any time. Generally, inter-seasonal low-temperature energy storage is not required. [0005] In winter, the sun angle is low, and the intensity of sunlight radiation is weak. In some areas, there is smog, and the intensity of sunlight radiation further decreases. Low-temperature energy is rarely needed, and a large amount of low-temperature energy is needed in winter. It is of practical significance to store solar energy at low temperature across seasons. [0006] However, the core iss...

[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 thermal water tank and the heated soil. It is used to take out the thermal energy in the thermal water tank and the soil at night or on a sunny day to heat the greenhouse. The pipes in the tank are buried at a depth of 1-3 meters, generally The validity period of energy storage is within 15 days, and inter-seasonal energy storage cannot be realized. If the tank depth continues to increase, the construction cost is very high, and it is difficult to realize economical energy storage and energy use
