Detailed Description
The following describes specific embodiments of the present application in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the application, are not intended to limit the application.
Referring to FIG. 1, a first exemplary embodiment of the application provides a heat exchange system for a stove, comprising:
A flue gas channel including a plurality of heat exchange tubes and a plurality of heat exchange guide structures, each heat exchange tube extending along a first direction, the plurality of heat exchange tubes being sequentially arranged at intervals along a second direction perpendicular to the first direction, the plurality of heat exchange guide structures being distributed at both ends of the plurality of heat exchange tubes to define a flue gas channel (which may refer to solid arrows in FIG. 1, represent flue gas flow direction) extending circuitously with the plurality of heat exchange tubes, and
The plurality of air guide baffles 5 are sequentially arranged at intervals along the first direction, at least a part of heat exchange tubes are penetrated and connected to each air guide baffle 5, and any two adjacent air guide baffles 5 are mutually staggered along the second direction, so that the plurality of air guide baffles 5 jointly define a roundabout extending clean air channel (the direction of hot air (namely clean air) can be indicated by dotted arrows in fig. 1).
In the heat exchange system of the hot blast stove, the time that the flue gas remains in the hot blast stove can be greatly prolonged by arranging the circuitous extending flue gas channel, and the circuitous extending and the air purifying channel which is arranged in a crossing way with the flue gas channel are limited by the plurality of air guiding clapboards 5, so that the heat exchange path of air (namely air purifying) can be greatly prolonged, the wind speed can be improved to improve the convection heat exchange coefficient, and the heat exchange efficiency can be effectively improved. Because the heat exchange efficiency is improved, simultaneously, a plurality of heat exchange pipes are closely arranged and the air guide baffle 5 and the heat exchange pipes are mutually perpendicular to be arranged, the circuitous extending flue gas channel and the clean air channel can be compactly arranged, and the purpose of heating air to the expected temperature by using a small number of heat exchange pipes is achieved, so that the overall size of the heat exchange system can be reduced, and the occupied space is saved. Furthermore, only a single clean air channel is arranged in the heat exchange system, and the air heating paths are consistent, so that the condition of uneven temperature of hot air can be effectively avoided.
In some embodiments, referring to fig. 1, each of the air guide partitions 5 is perforated with all heat exchange tubes. By the arrangement, the clean wind in the clean wind channel can be ensured to pass through all heat exchange tubes before flowing to the turning position of each channel, namely, the clean wind can exchange heat with all the heat exchange tubes for many times in the process of running the whole clean wind channel, so that the heat exchange effect can be further improved.
In some embodiments, each heat exchange tube extends vertically, and a plurality of heat exchange tubes are arranged at intervals in sequence in the transverse direction. At least two heat exchange tubes with different tube diameters are arranged in the flue gas channel, and the heat exchange tube with relatively large tube diameter is arranged at the upstream of the heat exchange tube with relatively small tube diameter along the upstream and downstream directions of the flue gas channel.
It should be noted that, the flue gas in the flue gas channel comes from the furnace, because the particle content in the flue gas just discharged from the furnace is higher, causes the granule to adhere to the intraductal wall of heat exchange tube easily, influences the heat transfer effect, has the risk of jam pipeline. Therefore, the heat exchange tube with relatively large tube diameter is adopted at the relatively upstream region in the flue gas channel, so that sedimentation of particles and cleaning of the pipeline can be facilitated, and the risk of blocking the pipeline due to adhesion of the particles is reduced. And the region of the flue gas channel, which is positioned at the relatively downstream position, can adopt heat exchange pipes with relatively smaller pipe diameters, and a larger number of small-pipe-diameter heat exchange pipes can be arranged in the same space, so that the heat exchange area of clean wind and the heat exchange pipes can be increased, and the heat exchange effect is improved.
For example, referring to fig. 1, the plurality of heat exchange tubes includes a plurality of primary heat exchange tubes 12 and a plurality of secondary heat exchange tubes 4, the tube diameters of the primary heat exchange tubes 12 are the same, and the tube diameters of the secondary heat exchange tubes 4 are the same, and the tube diameters of the primary heat exchange tubes 12 are larger than the tube diameters of the secondary heat exchange tubes 4. In combination with the foregoing, the plurality of primary heat exchange tubes 12 should be arranged upstream of the plurality of secondary heat exchange tubes 4 at this time.
When the flue gas passes through the plurality of primary heat exchange pipes 12, particles in the flue gas are convenient to settle due to the large pipe diameter of the primary heat exchange pipes 12, and a large number of particles are prevented from entering the secondary heat exchange pipes 4. The two-stage heat exchange tubes 4 are smaller in tube diameter and more in number, so that the heat exchange area of the clean wind and the heat exchange tube group can be effectively increased, and the heat exchange effect is improved.
Further, if the actual application conditions are combined, the pipe diameter of the primary heat exchange pipe 12 can be set to be not smaller than 100mm, and/or the pipe diameter of the secondary heat exchange pipe 4 can be set to be not larger than 60mm.
In some embodiments, each heat exchange tube extends vertically, and a plurality of heat exchange tubes are arranged at intervals in sequence in the transverse direction. At this time, referring to fig. 1, the plurality of air exchanging and guiding structures include a plurality of first air guiding boxes 8 and a plurality of second air guiding boxes 7, the plurality of first air guiding boxes 8 are located above the plurality of heat exchanging pipes and are sequentially arranged along the second direction, and the plurality of second air guiding boxes 7 are located below the plurality of heat exchanging pipes and are sequentially arranged along the second direction. Wherein, the upper end of each heat exchange tube all communicates one of them first air guide box 8 and the lower extreme all communicates one of them second air guide box 7. In the upstream-downstream direction of the flue gas channel, the channel inlet of the flue gas channel is formed in the most upstream first air guide box 8 and the channel outlet (i.e., the flue gas channel outlet 3) is formed in the most downstream first air guide box 8.
Referring to fig. 1, solid arrows indicate the flow direction of the flue gas, after the flue gas is discharged from the furnace, the flue gas enters the flue gas channel from the flue gas channel inlet in the first air guide box 8at the most upstream, then enters one second air guide box 7 at the most upstream through the heat exchange tube, particle sedimentation and turning of the flue gas are realized in the second air guide box 7, and the flue gas after turning enters the next first air guide box 8 through the heat exchange tube. And so on until the flue gas enters the first air guide box 8at the most downstream, the flue gas can be discharged out of the heat exchange system from the flue gas channel outlet 3 of the first air guide box 8.
In the process, the second air guide box 7 has the functions of guiding the flue gas to turn and collecting the settled flue gas particles, and is simple and reliable in structure.
It should be noted that the reversing air guiding structure is not limited to adopting the form of air guiding box, for example, the reversing air guiding structure can also adopt an elbow, and two adjacent heat exchange pipes can be connected through the elbow, so that the flue gas can be guided to turn.

In some embodiments, the outer wall of the furnace 11 is provided with outwardly radiating fins 10, which fins 10 are arranged close to the channel inlet of the clean air channel. Therefore, not only can the heat dissipation of the hearth 11 be enhanced, but also the heat dissipation heat can be utilized to preheat the air before flowing into the heat exchange system, so that the heat dissipation efficiency of the hearth and the heat exchange efficiency of the air are improved.

At the same time, the air inducing mechanism 9 operates to introduce air outside the hot blast stove into the detour air purifying passage, so that the air exchanges heat with the plurality of heat exchange tubes to generate hot air. And then hot air flows into the heat preservation room through the furnace body clean air outlet 6 for drying and utilization, and air (comprising preheated waste hot air) in the heat preservation room can enter the hot blast stove through the furnace body clean air inlet 2, so that the cyclic utilization of clean air is realized, the energy utilization rate can be improved, and the cost is saved.
