Heat exchanger system for generating and strengthening negative pressure

Abstract

The invention discloses a heat exchanger system for generating and strengthening negative pressure. The heat exchanger system comprises a waste gas flow equalizing pipe, connection branch pipes, guideblade fixing plates, waste gas channels and nozzles; the multiple guide blade fixing plates are installed around the same center of a circle in the circumferential direction and internally comprise the waste gas channels, industrial waste gas is guided into the waste gas flow equalizing pipe, thus, the waste gas uniformly flows into the waste gas channels in the guide blade fixing plates throughthe uniformly-distributed connection branch pipes at the same flow speed, the waste gas exchanges heat with external hot gas flow in the process of circulating in the waste gas channels, and finally,the waste gas is injected out through the waste gas nozzles in the tangential direction of waste gas outlets. The guide blade fixing plates of the heat exchanger system have the function of flow guiding and the function of a heat exchanger, the large heat exchange area and the long heat exchange time are ensured to the greatest extent through the waste gas channels in the guide blade fixing plates, by heating the external gas flowing through the system, the larger and stable temperature difference is provided, and higher negative pressure and the stable negative pressure zone are formed.

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...

[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
