Problems solved by technology

[0004] However, most of these air equalizers are mesh-shaped or vertical ventilation holes are set on the air equalizers. The structure is relatively complicated, and it is not suitable for the smoker economizer, which will greatly reduce the exhaust volume of the smoker. , has a limited effect on improving the heat transfer efficiency

Embodiment

[0020] Such as Figure 1-2 As shown, a deflector used for a smoker economizer, four hollow round tubes 2 are welded on a spherical base 1; the guide vane is installed at the fresh air inlet 5 of the smoker economizer 3 as a whole Between the entrance and the round tube inside the smoker economizer, actually it is the front baffle of the round tube inside the smoker economizer). The center of the top of the spherical base is the center of the airflow, and the spherical center of the spherical base, the center of the airflow, and the section center of the fresh air inlet are three points and one line. Fresh air enters the smoker economizer 3 from the fresh air inlet, and part of the air flow directly enters the middle four round tubes of the smoker economizer 3 through the four hollow round tubes welded on the deflector for heat exchange; the other part hits the spherical surface After the airflow center of the base, it is distributed along the spherical surface to twelve round...

Abstract

The invention discloses a flow guiding piece for an energy-saving device of a smoking furnace. The flow guiding piece comprises a spherical surface base, wherein a group of hollow round tubes are arranged on the spherical surface base, and the hollow round tubes form flow guiding channels on the spherical surface base; and the adjacent hollow round tubes are arranged in parallel to form a flow guiding gap in the spherical surface base. The flow guiding piece has the beneficial effects that the flow guiding piece is simple in overall structure, good in airflow dispersion effect and capable of effectively improving the heat exchange efficiency of the energy-saving device of the smoking furnace, does not affect the exhaust quantity, has a remarkable effect on improving the heat exchange efficiency of the energy-saving device, and can be better applied to the energy-saving device of the smoking furnace.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a deflector used for an economizer of a smoke furnace. Background technique [0002] Energy saver is an important equipment for energy saving and emission reduction, improving resource utilization and reducing environmental pollution. Economizers generally use baffles to guide fluid flow and extend flow channels, but rarely use deflectors. The deflector is installed at the fresh air inlet of the economizer, which plays the role of dispersing the air flow, making the heat exchange more uniform, and improving the heat exchange efficiency of the heat exchanger. At present, there is no guide vane specially used for smoker economizer, but there are many designs of air equalizers in similar fields. [0003] The Chinese patent number is: 201510912783.5 provides an air uniform plate, including a plate body and a plurality of through-hole arrays with the same hole pattern arranged...
