[0003] However, the height of the chimney in this type of solar chimney power station structure is often as high as hundreds of meters or even thousands of meters, which is too difficult to construct and has certain operational risks
In addition, the incident angle of light is different at different times, and the partial projection of the chimney on the heat collection shed will lead to low local temperature, which will affect the air flow balance in the system and reduce the maximum temperature rise of the hot air flow, which will affect the overall temperature of the seawater desalination system. even more

The invention discloses a heat exchanger system for generating and intensifying negative pressure, which comprises exhaust gas uniform flow pipes, connecting branch pipes, guide vane fixing plates, exhaust gas passages and nozzles; Installation, the inside of the guide vane fixed plate includes an exhaust gas channel, which introduces industrial exhaust gas into the exhaust gas equalizing pipe, so that the exhaust gas flows into the exhaust gas channel inside each fixed guide vane plate at the same flow rate through the uniformly distributed connecting branch pipes, and the exhaust gas flows through the exhaust gas channel. During the heat exchange with the external hot air flow, the exhaust gas is finally ejected from the exhaust gas nozzle along the tangential direction of the exhaust gas outlet. The guide vane fixing plate of the present invention has the functions of flow guide and heat exchanger at the same time. The exhaust gas channel inside the guide vane fixing plate ensures the heat exchange area and heat exchange time as large as possible. By heating the gas flowing through the outside, it provides more A large and stable temperature difference forms a stronger negative pressure and a stable negative pressure zone.
Description
technical field [0001] The invention belongs to the technical field of heat exchange, and in particular relates to a heat exchanger system for generating and strengthening negative pressure. Background technique [0002] Using solar energy for power generation and seawater desalination can make full use of solar radiation energy. Existing solar power generation and seawater desalination devices, such as the existing patent 200810021605.3 discloses a chimney power generation and seawater desalination device using solar energy, the solar chimney power generation and solar seawater desalination devices are combined, and the solar energy conversion efficiency is greatly improved , while being able to add fresh water output. [0003] However, the height of the chimneys in this type of solar chimney power station structure is often as high as hundreds of meters or even thousands of meters, which is too difficult to construct and has certain operational risks. In addition, the in...
