Urban geothermal energy street lamp

Abstract

The invention discloses an urban geothermal energy street lamp which comprises a street lamp body, a generator, a turbine motor and a heat collector. The street lamp body is composed of a lamp column arranged at the middle position of the street lamp body, a lamp cap arranged at the top of the lamp column, a lamp bulb arranged in the lamp cap and a lamp holder arranged at the bottom of the lamp column. The lamp bulb is embedded in the lamp cap, and meanwhile the lamp cap and the lamp holder are arranged perpendicularly to the lamp column. Power supply equipment is arranged on one side of the street lamp body. According to the urban geothermal energy street lamp, an automatic cleaning device is arranged, and therefore corrosion prevention and scale prevention can be achieved, cleanliness can be kept, and the service life of geothermal energy conversion equipment can be prolonged; meanwhile, a tail water treater is arranged, and therefore geothermal tail water can be treated, the national emission standard can be completely met, the ecological environment is prevented from being polluted, and extracted mineral substances can also be used for medical treatment or chemical engineering; and a thermal accumulator is arranged, the geothermal energy storage time is long enough, use is quite convenient, and wide application prospects are achieved in the field of future geothermal energy utilization.

Description

technical field [0001] The invention relates to the technical field of geothermal energy utilization, in particular to a geothermal energy street lamp for urban use. Background technique [0002] The so-called utilization of geothermal energy, of course, refers to the utilization of underground thermal energy to serve human beings after the development of underground thermal energy. Comprehensive utilization, double-cycle power generation, heating, cooling, greenhouse, bathing, industrial drying, industrial thermal processing, recovery of salt, canned food, domestic hot water, aquaculture, dehydration processing, soil heating, raising livestock, etc., and now many In order to improve the utilization rate of geothermal energy, the country adopts the method of cascade development and comprehensive utilization, such as cogeneration of heat and power, triple generation of heat, electricity and cooling, first heating and then breeding, etc., which not only saves resources, but also...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing geothermal energy street lamps do not have anti-corrosion and anti-scaling equipment, so they cannot be kept clean, which shortens the service life of geothermal energy conversion equipment. Causes pollution, and the storage time of geothermal energy is not long enough, so it is very inconvenient to use geothermal energy
