[0018] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure.

[0019] In the description of the present disclosure, it should be understood that the terms "up", "down", "left", "right", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the disclosed product is conventionally placed when in use, or are the orientations or positional relationships conventionally understood by those skilled in the art. These are merely for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present disclosure.

[0020] A waste heat cooling system for a live duck slaughter shed, such as Figure 1 Shown, including:

[0021] Slaughter shed 1 is located outdoors and is used for centralized raising of live ducks;

[0022] Slaughterhouse 2, which has built-in air conditioning and is used by staff to handle live ducks;

[0023] The heat exchange device includes a heat exchanger 3 and a surface cooler 4 connected in sequence to form a loop. The water inlet of the heat exchanger 3 is connected to the underground water pool 6 through the underground water supply pump 5. After the heat exchange, the working medium I with residual heat and the low-temperature working medium II circulate inside. The low-temperature working medium II flows to the surface cooler 4. After the air passes through the surface cooler 4 and exchanges heat energy with the low-temperature working medium II, it generates cold air and is transported to the slaughter shed 1 through the centrifugal fan;

[0024] Among them, the working medium I produced by the heat exchanger 3 can be transported to the slaughterhouse 2 for use.

[0025] It should be noted that, in this embodiment, the heat exchanger 3 is a plate-type heat exchanger 3 , and the surface cooler 4 is a tube-type surface cooler 4 .

[0026] In one specific embodiment, Figure 1 As shown, a circulating water pump 10 is connected between the heat exchanger 3 and the surface cooler 4. The water inlet of the circulating water pump 10 is connected to the water outlet of the heat exchanger 3 through a pipeline, the water outlet of the circulating water pump 10 is connected to the water inlet of the surface cooler 4 through a pipeline, and the water outlet of the surface cooler 4 is connected to the heat exchanger 3 through a pipeline.

[0027] On the basis of the above embodiment, the water inlet of the heat exchanger 3 is connected to the pure water supply pump 7 through the water supply pipeline, and the water inlet of the pure water supply pump 7 is connected to the pure water pool 8 through the pipeline. The pure water provided by the pure water supply pump 7 can not only play a pre-cooling role and improve the heat exchange efficiency of the heat exchanger 3, but also can replenish water to the circulation system, that is, the pure water coming out of the surface cooler 4 will be mixed with the replenishment water from the pure water supply pump 7 to form a circulation.

[0028] It should be noted that, in this embodiment, the water inlet into the cooler 4 mainly depends on the pure water supply pump 7 , which can avoid scaling inside the cooler 4 and is beneficial to improving the service life and heat exchange efficiency of the cooler 4 .

[0029] In one specific embodiment, an electric valve 9 is provided on the pipeline between the groundwater supply pump 5 and the groundwater tank 6 to ensure the groundwater supply.

[0030] The working process and beneficial effects of the present invention are as follows: when it is necessary to lower the temperature in the slaughter shed, the temperature difference between the ambient temperature and the groundwater can be utilized, and the working medium I with waste heat and the low-temperature working medium II are replaced through the heat exchanger 3. The low-temperature working medium flows to the surface cooler 4. The air exchanges heat energy with the low-temperature working medium II through the surface cooler 4 to generate cold air, which is transported to the slaughter shed 1 through the centrifugal fan to reduce the temperature in the slaughter shed 1, and the working medium I with waste heat can be transported to the slaughter workshop 2 for use, thereby alleviating the phenomenon of workers' hands getting icy due to long-term use of water in a low-temperature environment.

[0031] Among them, using groundwater as a refrigerant will not damage the atmospheric ozone layer and is environmentally friendly. There is no compressor and only a pump is used for circulation, which saves more energy.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
