Ground temperature-adjusting snow-melting device and temperature-adjusting ground structure using natural geothermal heat

Abstract

The invention relates to a ground temperature-regulating snow-melting device utilizing natural geothermal energy and its application, belonging to a geothermal utilization system, in particular to a snow-melting device for snow and ice removal. It includes a heat collection part and a heat dissipation part. The heat collection part is connected with the heat dissipation part through the output pipe and the return pipe to form a closed circuit. The characteristic is that the circuit is equipped with a low boiling point working fluid. The cooling tube is connected with the collecting tube through the return part, the collecting tube is located under the cooling tube, the two ends of the cooling tube are respectively connected with the output tube and the return part, and the two ends of the collecting tube are respectively connected with the return part and the return part. The upper ends of the pipes are connected, and the collecting pipe is continuously inclined downward from the return part to the return pipe, and the inclination is less than 1:10. The invention utilizes the heat medium with a low boiling point in the heat collector to absorb underground heat energy, and the heat medium after absorbing heat and gasification directly transmits heat to the radiator installed under the ground or road surface, so as to prevent frost and snow from remaining on the ground or road surface Or the effect of melting frost and snow, it does not consume extra energy, is environmentally friendly and economical, and can ensure the smooth flow of roads.

Description

technical field [0001] The invention belongs to a geothermal utilization system, in particular to a ground temperature-adjusting and snow-melting device that utilizes natural underground thermal energy to remove snow and ice. Background technique [0002] In recent years, with the rapid development of China's economy, the country's investment in infrastructure construction has continued to increase, and many expressways, expressways and airports have been built and used one after another, providing great convenience for people's production, life and travel. However, in the winter and spring seasons in some northern regions, due to frequent snowfall and large temperature difference between day and night, it is easy to form snow or freeze on the road surface, seriously affecting the driving safety of vehicles or aircraft, and causing great safety hazards. In the past, for the snow on the road surface, it was mainly to use manual or snow removal vehicles to clear snow or spread...

Problems solved by technology

However, since this technical solution uses antifreeze as a heat exchange medium, once the antifreeze denatures and freezes and solidifies, the pipeline will be blocked, making the system unable to achieve normal heat circulation. Therefore, the antifreeze must be replaced regularly, and the cost is relatively high. high

Moreover, this technical solution also uses heat exchange devices to perform a heat exchange in the middle, which inevitably produces heat loss and reduces the utilization rate of geothermal energy.

In addition, installing a circulating pump in the pipeline increases energy consumption on the one hand and brings new pollution on the other hand

Therefore, this technical solution has some obvious deficiencies no matter from an economic point of view or from an environmental point of view.

[0003] In addition, when the temperature of vegetable greenhouses is low in winter, it is necessary to use soil heating to burn coal to raise the ground temperature and greenhouse temperature, which wastes energy and increases emissions
