Description

Technical Field

[0001] The utility model belongs to the technical field of waste heat utilization, and in particular relates to a device for utilizing waste heat from waste gas of an incubator. Background Art

[0002] When incubating eggs, the incubator needs to maintain the ability to regulate internal temperature and humidity to ensure successful hatching. In order to maintain appropriate temperature and humidity, the incubator is usually equipped with heating equipment and humidity control devices. These devices will generate a certain amount of waste heat during operation. This part of the waste heat needs to be recycled to reduce energy waste. The waste heat recovery of the incubator requires corresponding waste heat utilization devices.

[0003] The patent specification with publication number CN203692174U discloses a device for utilizing waste heat from waste gas of an incubator. The gas heat exchange device is composed of a gas heat exchange outer tube sleeved on a gas heat exchange inner tube, the two ends of the gas heat exchange outer tube are closed, and openings are respectively provided on the right side of the upper tube wall of the gas heat exchange outer tube and the left side of the lower tube wall. The right side opening of the upper tube wall of the gas heat exchange outer tube and the right side of the gas heat exchange inner tube are respectively connected to gas filters, the left side of the gas heat exchange inner tube is connected to the exhaust port of the incubator, the left side opening of the lower tube wall of the gas heat exchange outer tube is connected to the right side of the supplementary heating device, the left side of the supplementary heating device is connected to the air inlet of the incubator, and an electric heating pipe is installed in the supplementary heating device.

[0004] The disadvantage of this technical solution is that since the factory incubates eggs in a centralized manner, there is a large amount of waste heat, so sufficient energy exchange space and time are required to recover the waste heat. This technical solution only performs heat exchange through a single-layer gas heat exchange inner tube. Since the exchange stroke is too short, the heat exchange time and space are insufficient, resulting in a low waste heat recovery rate.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 3 As shown, the device for utilizing waste heat from waste gas of an incubator comprises a bottom frame 1 and a bottom frame 2, a bottom exchange tank 3 is installed between the bottom surfaces of the bottom frame 1 and the bottom frame 2, a top exchange tank 4 is installed between the bottom exchange tank 3 and the upper part of the bottom frame 2, a hot air inlet pipe 5 is arranged at the bottom of one end of the bottom exchange tank 3, and a heat flow output pipe 6 is arranged at the bottom side of the other end, a cold air output pipe 7 is arranged at the top end of the top exchange tank 4 just above the hot air inlet pipe 5, and a cold flow input pipe 8 is arranged at the top end of the top exchange tank 4 just above the heat flow output pipe 6, the bottom exchange tank 3 and the top exchange tank 4 have the same structure, and are symmetrically connected with respect to adjacent surfaces.

[0022] like Figure 2 and Figure 3As shown, the bottom exchange tank 3 and the top exchange tank 4 have the same structure and are collectively referred to as tank bodies below. A plurality of gas baffles 9 are fixedly connected horizontally inside the tank body. The gas baffles 9 are evenly and staggeredly arranged along the bottom and top of the inner wall of the tank body, and the height of the gas baffles 9 is 65% of the inner diameter of the tank body; an inner baffle 10 is fixedly connected to one side of the tank body, a flow storage chamber 11 is arranged on the side of the inner baffle 10 away from the gas baffle 9, a flow baffle 12 is fixedly connected horizontally between the flow storage chamber 11 and the inner baffle 10 in the middle, a gas pipe 13 is fixedly connected to the side of the inner baffle 10 close to the gas baffle 9, and a flow pipe 14 is fixedly connected to the side of the inner baffle 10 close to the flow baffle 12, and the gas pipe 13 and the flow pipe 14 on the adjacent sides of the bottom exchange tank 3 and the top exchange tank 4 are fixedly connected accordingly;

[0023] A large number of U-shaped tubes 15 are evenly and fixedly connected between the inner partition 10 and the air partition 9 inside the tank body. The two end openings of each U-shaped tube 15 are connected to the flow storage chamber 11, and the two openings of each U-shaped tube 15 are arranged on both sides of the flow partition 12; at the same time, the staggered air partitions 9 with a height exceeding half of the inner diameter can force the airflow to pass through each U-shaped tube 15 in an "S"-shaped bending path, thereby increasing the heat exchange contact area.

[0024] The working principle of the utility model is that the incubator will discharge a large amount of hot air during the incubation process. In order to reuse the hot air, the hot air is injected into the Figure 2 The hot air at the bottom side of the middle bottom exchange tank 3 is connected to the hot air inlet pipe 5, and the cold fluid (usually cold water) is injected into the top exchange tank 4 from the cold flow inlet pipe 8 at the top side of the top exchange tank 4, and then the air flows upward and the cold flow flows downward; specifically, the hot air flow first enters the bottom exchange tank 3, and fills between the inner partition 10 and each air partition 9. Due to the increase in air pressure and the alternating obstruction of each air partition 9, the hot air flow passes through the bottom exchange tank 3 in an "S" shape to the maximum extent, and finally passes through the top of the bottom exchange tank 3. The gas pipe 13 at the bottom and the gas pipe 13 adjacent to the bottom of the top exchange tank 4 are injected into the top exchange tank 4. Due to the obstruction of the inner partition 10 of the bottom exchange tank 3 and the top exchange tank 4, the airflow cannot enter the storage chamber 11, so it continues to bend in the top exchange tank 4 and is finally discharged from the cold air output pipe 7 on the top exchange tank 4. The hot air flow bypasses through the continuous bending of the two connected tank bodies to achieve the heating of the cold fluid in the internal U-shaped tube 15. In the process of heat exchange, the hot air flow is also changed into cold air flow for discharge;

[0025] Corresponding to this process is the heating of the cold fluid. Specifically, after the cold fluid enters the storage chamber 11 of the top exchange tank 4, it is blocked at the top of the storage chamber 11 by the flow baffle 12, and then enters the upper half port of each U-shaped tube 15, and then enters the interior of the U-shaped tube 15, and heat exchange is achieved with the heating of the upward hot air flow. The fluid in the U-shaped tube 15 flows into the lower half of the interior of the top exchange tank 4, and then enters the lower half of the storage chamber 11 through the other end of the U-shaped tube 15, and then enters the bottom exchange tank 3 through the flow pipe 14 connected to the bottom exchange tank 3 and the top exchange tank 4, and then repeats the flow process of the top exchange tank 4, and finally from the bottom of the storage chamber 11 of the bottom exchange tank 3 The heat flow is discharged through the heat output pipe 6; in this process, since the cold flow descends from the top of the top exchange tank 4 to the bottom of the bottom exchange tank 3, its path is opposite to the upward path of the hot air, and heat exchange occurs with the external hot air flow when passing through the U-shaped tube 15, and finally the hot air flow generated by the incubator heats the cold flow, and the hot air flow completes the heat exchange and is discharged, and the heat flow is then used to increase the incubation environment temperature in the incubator, thereby realizing energy recycling; and in this process, since the cold and hot flows have a long passage path and a long residence time, the U-shaped tube 15 separates the cold flow to be heated, thereby increasing the contact area of ​​the heat exchange, thereby realizing efficient heat energy recycling, that is, greatly improving the heat energy recovery rate.

[0026] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
