Ceramic solar hot water energy storage device built by punching in deposit soil layer through pile driving and drawing machine

Abstract

The invention discloses a ceramic solar hot water energy storage device built by punching in a deposit soil layer through a pile driving and drawing machine, and relates to a solar hot water energy storage device. The pile driving and drawing machine is used for punching in the deposit soil layer through a steel pipe pile, high-pressure water or high-pressure mud is injected into the steel pipe pile to reduce the friction force of pile driving and drawing and protect a hole wall, the punching depth is 30 meters, when a rock layer is encountered in the middle, the punching work is stopped, anda polyethylene tube tank combiner is inserted into the deposit soil layer hole with the hole depth of 5-30 meters. A heating energy storage system in the deposit soil layer is formed through horizontal communicating pipes, the water volume of a thermal insulation water tank of a ceramic solar roof and a ceramic solar water heating system is equal to the value of the square meter of a ceramic solarpanel multiplied by 30 L, in spring, summer and autumn, local water is used to produce hot water at 60 DEG C to 100 DEG C, and the hot water is circulated in the heating energy storage system in thethermal insulation water tank and the deposit soil layer, so that the solar energy obtained in spring, summer and autumn is converted into stored energy in the deposit soil layer, and hot water heatedby the stored energy in the deposit soil layer is used for heating a building, a greenhouse and a biogas digester in winter.

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...

Problems solved by technology

[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.
