Abstract

The invention discloses an adjusting device and method applied to Stirling engine heating pipe overtemperature. The adjusting device applied to the Stirling engine heating pipe overtemperature comprises a pipeline and a heat collection cavity; the pipeline is arranged on the inner wall of the heat collection cavity; and the pipeline communicates with a cooling water source. When the pipe wall temperature of a heating pipe exceeds a preset threshold, a controller controls to open a solenoid valve used for controlling water on-off in the pipeline to make water in the pipeline flow, the inner wall temperature of the heat collection cavity drops rapidly, radiation heat exchange amount of the inner wall of the heat collection cavity and the heating pipe is increased due to the inner wall temperature drop of the heat collection cavity, and then the temperature of the heating pipe is reduced. Light spots do not need to be cut and operation of a power generation device does not need to be paused, when the pipe wall temperature of the heating pipe is overtemperature, the operation is even more stable, electricity generation can not be broken off, and the stability of power output is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of Stirling engines, and in particular relates to an over-temperature regulating device and method suitable for heating tubes of Stirling engines. Background technique [0002] When the dish-type Stirling power generation device is operating in the field, when the light intensity exceeds the design value, the pressure may have reached the upper limit at this time, which may cause the heating pipe or heat-absorbing parts to overheat. The measures taken can only ensure the safety and reliability of the power generation device by removing the light spot. However, the removal of the light spot will not only reduce the power generation of the power generation device instantaneously, causing fluctuations to the power grid, but also make the solar energy during the time of cutting the light spot unusable, resulting in a decrease in efficiency. Contents of the invention [0003] In order to solve the technical pr...
