Description

Technical Field

[0001] This utility model relates to the field of boiler flue gas recovery technology, specifically to a boiler flue waste heat recovery guide plate. Background Technology

[0002] In the field of boiler flue gas recovery technology, flue gas recovery devices are one of the key pieces of equipment for improving energy utilization efficiency. Traditional boiler flue gas recovery devices mainly achieve flue gas recovery and heat utilization through a direct connection between the flue and the recovery device. However, this simple connection method has many technical shortcomings.

[0003] In traditional flue gas recovery processes, the flow characteristics of flue gas within the flue often lead to uneven contact between the flue gas and the recovery device. This uneven contact not only reduces heat transfer efficiency but also prevents some areas of the recovery device from being fully utilized, thus affecting the overall flue gas recovery rate. Secondly, moisture carried in the flue gas condenses into condensate during the cooling process. Traditional recovery devices often fail to effectively address the collection and discharge of condensate, causing it to accumulate inside the device. This not only affects heat transfer but may also cause corrosion and damage to the device. Utility Model Content

[0004] The present invention aims to provide a solution to the problem that existing boiler flue gas recovery devices are directly connected to the boiler, resulting in uneven contact between the flue gas and the recovery device and thus low flue gas recovery and utilization rate.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a boiler flue waste heat recovery guide plate, including a guide plate and a plurality of air guide holes disposed on the guide plate, wherein the air guide holes include raised air guide holes and recessed water leakage holes.

[0006] The working principle of this utility model is as follows: The guide plate is connected between the boiler flue and the recovery device. The guide plate can be placed horizontally or at an angle. At this time, the flue gas in the boiler flue passes through the guide plate through the air guide hole and enters the recovery device. The condensate generated by absorbing the heat of the flue gas drips into the baffle of the guide plate. The condensate is blocked by the raised air guide hole and cannot drip down. The condensate flows on the top of the baffle until it drips from the concave water leakage hole to the designated position.

[0007] The beneficial effects of this utility model are as follows: 1. The design of the guide plate allows the flue gas to be more evenly distributed inside the recovery device when it enters through the air guide hole. This even distribution not only improves the heat transfer efficiency but also enhances the overall utilization rate of the recovery device, thereby significantly improving the flue gas recovery and utilization rate. 2. The air guide hole includes a raised air guide hole and a recessed drainage hole. This design allows condensate to be blocked by the raised air guide hole when it drips onto the guide plate, flowing at the top of the baffle until it drips from the recessed drainage hole to the designated position. This flow method not only avoids the accumulation of condensate inside the device but also effectively solves the problem of condensate collection and discharge. 3. The guide plate design of this utility model has a simple structure and does not use complex internal components. This simple structure not only reduces manufacturing costs but also makes the maintenance of the device more convenient. At the same time, because the design of the guide plate allows the flue gas to flow evenly through the air guide hole, the contact between the flue gas and the recovery device is more uniform, thus reducing device damage and maintenance costs caused by uneven contact.

[0008] Furthermore, the top edges of the guide plate are connected to baffles that do not obstruct the raised air vents and the recessed drain holes. By using these baffles, when excessive water accumulates on the guide plate, it is prevented from flowing into the recessed drain holes, thus avoiding water from flowing down through the gaps around the guide plate.

[0009] Furthermore, the spacing between the multiple raised air guide holes and recessed water leakage holes is the same. This equal spacing between the raised air guide holes and recessed water leakage holes ensures that the flue gas can enter the boiler flue gas recovery device evenly.

[0010] Furthermore, the diameters of the multiple raised air guide holes and recessed water leakage holes are the same. The equal spacing between the raised air guide holes and recessed water leakage holes further enhances the uniformity of flue gas flow.

[0011] Furthermore, the diameter of the multiple raised air guide holes is smaller than the diameter of the recessed water leakage holes. By setting the diameter of the raised air guide holes to be smaller than the diameter of the recessed water leakage holes, condensate can flow out from the recessed water leakage holes in a timely manner, preventing condensate overflow.

[0017] The reference numerals in the accompanying drawings include: guide plate 1, baffle 2, air guide hole 3, recessed water leakage hole 301, and raised air guide hole 302.

[0018] Implementation 1: Basic as attached Figure 1 -Appendix Figure 3 As shown: A boiler flue waste heat recovery guide plate 1 includes a guide plate 1 and baffles 2 arranged around the guide plate 1. Each baffle 2 has an air guide hole 3 at its bottom, which is not obstructed by the baffles 2. The air guide hole 3 includes a raised air guide hole 302 and a recessed water drain hole 301. The distance between the raised air guide hole 302 and the recessed water drain hole 301 is the same, and their diameters are the same. The raised air guide hole 302 is located at the center of the baffle 2, and the recessed water drain hole 301 is located at the outer edge of the baffle 2.

[0019] Example 2: The diameter of the raised air guide hole 302 is smaller than the diameter of the recessed water leakage hole 301.

[0020] The specific implementation process is as follows: The guide plate 1 is connected between the boiler flue and the recovery device. The guide plate 1 can be placed horizontally or at an angle. At this time, the flue gas in the boiler flue passes through the guide hole 3 and enters the recovery device through the guide plate 1. The condensate generated by absorbing the heat of the flue gas drips into the baffle 2 of the guide plate 1. The condensate is blocked by the raised guide hole 302 and cannot drip down. The condensate flows on the top of the baffle 2 until it drips from the recessed drain hole 301 to the designated position.
