A new type of full countercurrent rotating non-mixing heat exchanger

Abstract

The invention discloses a novel total-reverse-flow rotary non-mixing heat exchanger. The novel total-reverse-flow rotary non-mixing heat exchanger is characterized in that portions, except for a heat exchanger base, of the heat exchanger can rotate in service procedures, and the heat exchanger comprises a heat exchanger barrel, flow channel converters, inner seal heads of the heat exchanger, outer seal heads of the heat exchanger and the heat exchanger base; total-reverse-flow non-mixing rotary heat exchange effects can be realized for two channels of fluids, and the purpose of improving the heat exchange effects can be achieved. The heat exchanger barrel is a cylindrical barrel with two or an even number of internal barriers, the even number is larger than 2, the barrel is uniformly divided into an even number of equal portions by the barriers, a fan-shaped flow channel is formed by each left barrier, the corresponding right barrier and a cylindrical barrel portion sandwiched by the left barrier and the right barrier, and the flow channel converters are used as flow channel conversion devices. The novel total-reverse-flow rotary non-mixing heat exchanger has the advantages that the heat exchanger is used in fluid heat exchange places and is high in heat exchange efficiency, average heat exchange temperature difference and outlet temperature uniformity and free of mixing among the heat exchange fluids; the novel total-reverse-flow rotary non-mixing heat exchanger is wide in application and can be applied to heat transfer enhancement or temperature homogenization among different fluids in industrial application, and the like.

Description

technical field [0001] The invention relates to a novel full countercurrent rotating non-mixing heat exchanger, which belongs to the technical category of fluid heat exchange equipment. Background technique [0002] The heat transfer process is very common in industrial processes and daily life, and is one of the basic physical processes in nature. It is widely used in departments such as power, chemical industry, metallurgy, aerospace, air conditioning, refrigeration, machinery, textile, construction and so on. The heat transfer process is closely related to the cooling of microelectronic devices as large as a turbogenerator with a single unit power of 1.3 million kilowatts. Heat exchanger is a general-purpose equipment widely used in the heat transfer process. In oil refining enterprises, the equipment investment of heat exchanger accounts for about 25% of the total investment, and the weight of heat exchanger accounts for 20% of the total weight of equipment. Taking a p...

Problems solved by technology

At present, there are relatively few studies on dynamic heat exchangers. CN103175420A discloses a core rotary heat exchanger, which mainly increases the turbulence of the shell-side fluid of the tube-and-tube heat exchanger by rotating the heat exchange core. To achieve the purpose of enhancing the heat transfer effect
