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

Deformed example 2

[0081] As shown in Figure 19, on the high-temperature section temperature conduction area II313a, there are three circles of high-temperature section flow guide holes II313a-1 distributed radially from outside to inside, and each circle contains a plurality of circular holes II313a-1 arranged around the center, from The diameters of the circular holes from the outer ring to the inner ring decrease successively. The diameters of the circular holes II313a-1 in the same circle are different, and in the third circle (the innermost circle), only half of the circular holes II313a-1 are provided, and the other half are not provided with holes.

[0082] The structure of the temperature conduction area II313a in the high-temperature section in Modification 2 can use the difference in aperture size to form turbulent flow in both the radial and axial areas of the guide vane, thereby achieving better cooling effect and tar collection efficiency.

Deformed example 3

[0084] In the temperature conducting area 513a' of the low temperature section, the outer ends of some of the temperature conducting fins 513a-1' of the low temperature section are connected to the outer edge of the temperature conducting area 513a' of the low temperature section, and the outer ends of some of the temperature conducting fins 513a-1' of the low temperature section There is a certain distance between the end and the outer edge of the temperature conduction area 513a' of the low temperature section.

[0085] The structure of the low-temperature section temperature conduction area 513a' in Modification 3 makes the turbulent heat exchange efficiency between the end of the low-temperature section heat conduction fin and the outer edge of the temperature conduction area separated by a certain distance from the outer edge of the temperature conduction area more efficient. Higher, more conducive to refrigeration and collection.

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...
