Description

Technical Field

[0001] The invention relates to the technical field of heat exchange, and in particular to a guide plate used for an economizer of a fumigation furnace. Background Art

[0002] The economizer is an important device for energy saving and emission reduction, improving resource utilization and reducing environmental pollution. Economizers generally use baffles to guide fluid flow and extend the flow channel, but rarely use guide vanes. The guide vanes are installed at the fresh air inlet of the economizer to disperse the air flow, making the heat exchange more uniform, so as to improve the heat exchange efficiency of the heat exchanger. At present, there is no guide vane specifically used for economizers for smoke furnaces, but there are many designs of air distribution plates in similar fields.

[0003] Chinese patent number: 201510912783.5 provides a wind balancing plate, including a plate body and a plurality of through-hole arrays with the same hole shape arranged on the plate body, wherein each through-hole array corresponds to an anode cylinder in the electrostatic dust removal unit to achieve a better uniform air intake effect, thereby improving the dust removal efficiency. Chinese patent number: 201621200875.7 discloses a wind balancing plate structure for preventing oil fume adhesion for electrostatic oil fume removal equipment, including an electric field module and a wind balancing plate, the electric field module is fixed with a square tube bracket on its front side with an insulator as a fulcrum, the wind balancing plate is welded on the square tube bracket, the wind balancing plate is a punched screen with dense holes punched at the position corresponding to the electric field, the wind balancing plate structure can effectively solve the problem of oil stains adhering to insulators, and has the characteristics of strong anti-adhesion ability. The Chinese patent number is: 201920653091.7, which discloses an easily adjustable air equalizer, the air equalizer includes an air equalizer plate, a clamping portion arranged on the air equalizer plate, and a plurality of air regulating plates clamped on the clamping portion on the upper and lower sides, and a gap is left between adjacent air regulating plates for the air regulating plates to slide; the air equalizer plate is evenly distributed with ventilation holes, and the air regulating plate is evenly distributed with adjustment holes arranged corresponding to the ventilation holes, and the size of the adjustment holes is the same as the size of the ventilation holes. The air equalizer is improved in structure, and the size of the ventilation holes can be adjusted by sliding the air regulating plate, thereby achieving a better uniform air intake effect. In addition, the air equalizer divides the ventilation plate into several areas to realize the control of the ventilation volume in each area, so that the smoke can be evenly distributed in various areas of the purifier, ensuring that the wind speed of each part of the purification equipment is consistent, thereby improving the overall purification efficiency.

[0004] However, most of these air distribution plates are in mesh shape or have vertical ventilation holes on the air distribution plates, and have a relatively complex structure. They are not very suitable for smoke furnace energy savers, and will greatly reduce the exhaust volume of the smoke furnace, with limited effect on improving the heat exchange efficiency. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a guide plate with a reasonable structural design for a fumigation furnace economizer.

[0014] Figure 2 It is a schematic diagram of the installation structure of the present invention;

[0015] In the figure: 1-spherical base, 2-hollow round tube, 3-smoker energy saver, 4-round tube, 5-fresh air inlet, 6-fresh air outlet, 7-waste gas outlet, 8-waste gas inlet. DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-2As shown, a guide plate for a smoker economizer includes a spherical base 1, a hollow circular tube 2, a smoker economizer 3, a circular tube 4, a fresh air inlet 5, a fresh air outlet 6, an exhaust gas outlet 7 and an exhaust gas inlet 8.

[0018] In the present invention, a guide plate for a smoker economizer is mainly composed of a spherical base and a plurality of hollow circular tubes welded on the spherical surface; the guide plate is installed at the fresh air inlet of the smoker economizer to disperse the airflow. The center of the top surface of the spherical base is the center of the airflow. After the guide plate is installed on the smoker economizer, the center of the spherical base, the center of the airflow and the center of the fresh air inlet are in a straight line. During installation, the hollow circular tube on the guide plate is aligned with the circular tube inside the smoker economizer, and the size of the hollow circular tube is consistent with the size of the circular tube inside the smoker economizer. In the present invention, a thin shell structure is used to improve the rigidity and strength of the guide plate, which not only enables the airflow center to withstand a larger impact, but also reduces the thickness of the guide plate, saving the material of the guide plate.

[0019] Example:

[0020] like Figure 1-2 As shown, a guide plate for a smoke furnace economizer, four hollow round tubes 2 are welded on a spherical base 1; the guide plate is installed as a whole at the fresh air inlet 5 of the smoke furnace economizer 3 (between the fresh air inlet and the round tube inside the smoke furnace economizer, actually on the front baffle of the round tube inside the smoke furnace economizer). The top center of the spherical base is the airflow center, and the spherical center of the spherical base, the airflow center and the cross-sectional center of the fresh air inlet are in a straight line. Fresh air enters the smoke furnace economizer 3 from the fresh air inlet, and part of the airflow directly passes through the four hollow round tubes welded on the guide plate and enters the four middle round tubes of the smoke furnace economizer 3 for heat exchange; the other part hits the airflow center of the spherical base and is dispersed along the sphere to the twelve round tubes around the smoke furnace economizer (there are a total of sixteen round tubes in the economizer) for heat exchange. After the fresh air completes the heat exchange, it converges at the fresh air outlet and flows out of the smoke furnace economizer. The exhaust gas enters the smoker economizer 3 from the exhaust gas inlet 8, heats the outer wall of the sixteen circular tubes (flow channels) in the economizer, and then converges at the exhaust gas outlet 7 to flow out of the economizer. The guide vane has a simple structure and novel design. Through simulation research on economizers with and without guide vanes, it is found that the fresh air of the economizer without guide vanes mainly flows through the four middle pipes, resulting in low heat exchange efficiency, while the economizer with guide vanes has a good airflow dispersion effect, and the airflow is more dispersed to the twelve circular tubes around. Relatively speaking, the fresh air flows more evenly through the heat exchange pipes of the economizer, the heat exchange efficiency is effectively improved, and the exhaust volume is not affected.

[0021] If the internal heat exchange pipes of the economizer of the smoke furnace are arranged in concentric circles, then the several round tubes welded on the guide plate are also arranged in a circle and aligned with the internal heat exchange round tubes of the economizer, with the same size, and so on.

[0022] It is understandable that those skilled in the art can make equivalent substitutions and changes based on the technical solution and inventive concept of the present invention, and all these changes and substitutions should fall within the protection scope of the present invention.
