Description

technical field [0001] The invention belongs to the field of tar cooling and collecting, and in particular relates to a tar cooling and collecting device based on an asymmetric temperature-conducting flow channel. Background technique [0002] The partition wall heat exchanger is the most widely used type of industrial heat exchanger, and the shell-and-tube (also called shell-and-tube) heat exchanger is the most typical type, which has a long history in industrial applications. , still occupies a dominant position in the heat exchanger, and its core component is the setting of the baffle, which can prevent the short circuit of the fluid and increase the fluid velocity on the one hand, and on the other hand, force the fluid to cross-flow through the tube bundle multiple times according to the prescribed path. greatly increase the degree of turbulence. [0003] However, the shell-and-tube heat exchanger has a large size and complex piping, and it is necessary to fully conside...

Problems solved by technology

[0003] However, the shell-and-tube heat exchanger has a large size and complex piping, and it is necessary to fully consider the temperature difference inside the heat exchanger to eliminate thermal stress

[0004] In the tar collection device based on refrigeration fins, the uniform and symmetrical arrangement of the guide components can easily lead to gas short circuit, which makes the heat exchange and tar collection effect worse; at the same time, in the pipeline, the gas flow near the wall and the center of the pipeline There is a large difference in the gas fluidity at the location, and it is difficult to efficiently collect the tar in the gas with a uniform and symmetrical arrangement of the flow guide components
