Automatic steam flow adjusting device for geothermal energy power generation

Abstract

The invention discloses an automatic steam flow adjusting device for geothermal energy power generation. The device comprises a heat preservation steam cover, a communicating port is formed in the upper end of the heat preservation steam cover, a steam circulating pipe is connected to the communicating port in a sealed mode, an inverted-T-shaped block is connected to the inner wall of the upper end of the heat preservation steam cover through two lifting mechanisms, a buoyancy ball is fixedly connected to the side wall of the upper end of the inverted-T-shaped block, a conical cover is fixedlyconnected to the inner wall of the upper end of the heat preservation steam cover, and a plurality of fixing rods are fixedly connected to the inner wall of the conical cover. According to the device, a gap between the buoyancy ball and the conical cover can be automatically adjusted according to the water temperature and the steam amount, and then the steam flow is adjusted; the structure is simple, the flow adjusting effect is remarkably improved, the economic cost is low, and the installation is convenient; then the power stability of a steam generator during power generation is guaranteed, and therefore the safety of parts of the steam generator is protected, and the service life of the steam generator is long; and meanwhile, the energy consumption is guaranteed, and the utilization rate of geothermal energy is increased.

Description

technical field [0001] The invention relates to the technical field of geothermal energy, in particular to an automatic steam flow regulating device for geothermal energy power generation. Background technique [0002] Geothermal energy is natural thermal energy extracted from the earth's crust. This energy comes from lava inside the earth and exists in the form of heat. It is the energy that causes volcanic eruptions and earthquakes. Geothermal power generation is a new type of power source that uses underground hot water and steam. power generation technology. Its basic principle is similar to that of thermal power generation. It is also based on the principle of energy conversion. First, the geothermal energy is converted into mechanical energy, and then the mechanical energy is converted into electrical energy. There are two types of geothermal steam power generation: primary steam method and secondary steam method. Among them, the primary steam method directly Use unde...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the actual power of the steam generator in the prior art changes too much compared with the rated power, which will cause the components of the unit to fail, increase the burden of maintenance, and the energy consumption will also increase, reducing the power consumption of the generator. The efficiency of the problem, and proposed a geothermal energy steam flow automatic adjustment device
