Embodiment 1

[0021] as attached figure 1 As shown, the apparatus includes an upper heat exchanger and a lower heat exchanger, and a downdraft insulated conduit and an updraft insulated conduit connecting the upper heat exchanger and the lower heat exchanger together. The cross-section of the downdraft adiabatic conduit is four times that of the updraft adiabatic conduit. The lower end of the downflow heat insulation pipe is slightly lower than the lower heat exchanger, and is connected with the lower heat exchanger through the reducer. The updraft insulated conduit is connected to the upper heat exchanger through a diffuser. A part of the lower end of the downflow heat insulation conduit is lower than the lower heat exchanger, which is beneficial to control the direction of the airflow. In the updraft insulated duct, a turbine power generation system is installed.

[0022] In this example, the gas in the device is a mixed gas of nitrogen and hydrogen, and the hydrogen gas fraction is 3....

Abstract

The invention belongs to the technical field of power generator, in particular to an atmospheric temperature difference circulation airflow generating device. The atmospheric temperature difference circulation airflow generating device comprises a higher heat exchanger, a lower heat exchanger, a descending airflow heat-insulated guiding pipe and an ascending airflow heat-insulated guiding pipe, wherein the descending airflow heat-insulated guiding pipe and the ascending airflow heat-insulated guiding pipe connect the higher heat exchanger with the lower heat exchanger; the section of the descending airflow heat-insulated guiding pipe is at least two times that of the ascending airflow heat-insulated guiding pipe; the lower end of the descending airflow heat-insulated guiding pipe is slightly lower than the lower heat exchanger and is connected with the lower heat exchanger through a reducing pipe; the ascending airflow heat-insulated guiding pipe is connected with the higher heat exchanger through a diffuser pipe; the lowered temperature value after internal gas per unit volume ascends in the ascending airflow heat-insulated guiding pipe by the unit height in a heat-insulated mode is smaller than the lowered temperature value of air per unit volume at the same altitude outside the ascending airflow heat-insulated guiding pipe ascends by the unit height in a heat-insulated mode; and the gas ascends to the higher heat exchanger along the ascending airflow heat-insulated guiding pipe, then is cooled and descends to the lower heat exchanger along the descending airflow heat-insulated guiding pipe, and circulation flowing airflow power generation is achieved.

Description

technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to an atmospheric temperature difference circulating air flow generating device. Background technique [0002] In the troposphere, heated air rises to create air currents that can be used to drive turbines to generate electricity. Power generation technology based on heat engine theory occupies a relatively high proportion in modern power systems. Therefore, it is of great significance to improve its operating efficiency. According to the Carnot cycle theory, reducing the temperature of the low temperature source can increase the efficiency of the heat engine power generation system. [0003] According to the law of turbine power generation, the higher the airflow velocity, the higher the power generation and the lower the unit power cost. In this way, the use of high-speed airflow to generate electricity can reduce the cost of the turbine power generation sy...
