Description

Technical Field

[0001] The present invention relates to the technical field of heat exchangers, and specifically to a structure of a swirl heat exchanger. Background Art

[0002] A heat exchanger, also known as a heat exchanger, is a device that transfers part of the heat of a hot fluid to a cold fluid. The working principle of the heat exchanger is based on the principle of heat balance, that is, the heat of a high-temperature object always transfers to a low-temperature object. In the heat exchanger, the hot fluid and the cold fluid exchange heat through different methods (such as direct contact, shell-and-tube type, etc.) to achieve heat transfer. Heat exchangers include plate heat exchangers, shell-and-tube heat exchangers, and coil heat exchangers, etc.

[0003] The heat exchanger usually consists of multiple groups of heat exchange fins. When exchanging heat with hot fluids such as flue gas, since there are more impurities in the flue gas, after the heat exchanger is used for a period of time, it needs to be maintained and cleaned. The disassembly of the heat exchanger is rather troublesome and the operation is rather laborious. It is rather difficult to clean the impurities attached to the inner wall of the heat exchanger. During the heat transfer process, the energy inside the flue gas cannot be reused, resulting in a low heat conduction efficiency. Summary of the Invention

The guide vanes are of a spiral structure and are sleeved outside the inner cylinder. Multiple sliding grooves are provided on the heat transfer cylinders, so that the contact area between the hot fluid and the heat exchange water in the water storage tank is larger, ensuring the heat exchange efficiency. The inner cylinder and the guide vanes can be rotated out of the shell, making subsequent disassembly and maintenance more convenient. The flue gas contacts the inner wall of the inner cylinder and the heat transfer cylinders, and can heat the heat exchange water inside the water storage tank, absorbing the energy in the hot fluid. The flue gas can push the scraper to move. The scraper passes through the fixed cylinder along the square groove and contacts the outer surface of the guide vane, and can scrape off the dust and impurities on the guide vane, making the cleaning of the heat exchanger faster and facilitating maintenance, and is easy to use.
