Problems solved by technology

[0003] However, the steam in existing geothermal wells is used to heat low-temperature water, and then the steam is directly discharged into the air. The steam utilization rate is low, and it is rarely used for power generation, and the continuity of power generation is poor, resulting in a waste of energy.

Abstract

The invention provides an energy source gradient utilization system of a geothermal well. The energy source gradient utilization system of the geothermal well comprises a fixed pillar, a fixing mechanism, an air outlet and water outlet mechanism, a blowing mechanism and a power generation mechanism; the fixing mechanism is welded to the outer side wall of the fixed pillar; the air outlet and wateroutlet mechanism is installed on the inner part of the fixing mechanism; the bottom of the blowing mechanism communicates with the air outlet and water outlet mechanism located at the top of the fixed pillar, and the blowing mechanism comprises an air outlet pipe, an air collecting cover and an air gathering cover; and the power generation mechanism is installed at the top of the fixed pillar, and the power generation mechanism comprises fan blades, an electric generator and a supporting frame. According to the energy source gradient utilization system of the geothermal well, steam of the geothermal well can be used for generate electricity, the energy source can be utilized comprehensively, and the power generation persistence is high.

Description

technical field [0001] The invention relates to the technical field of geothermal well energy utilization, in particular to an energy cascade utilization system for geothermal wells. Background technique [0002] Geothermal wells refer to methods and devices for generating power from geothermal energy with a depth of about 3,500 meters or hot spring water with a water temperature greater than 30°C. Geothermal heat is divided into three categories: high temperature, medium temperature and low temperature. If it is higher than 150°C and exists in the form of steam, it belongs to high-temperature geothermal; if it exists in the form of a mixture of water and steam between 90°C and 150°C, it belongs to medium-temperature geothermal; if it is higher than 25°C and lower than 90°C, it belongs to warm water Existing in the form of hot water, hot water, etc., it belongs to low-temperature geothermal. [0003] However, the steam in existing geothermal wells is used to heat low-temper...
