Detailed Embodiments

[0019] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model. Embodiment 1

[0020] This example discloses a device for heat energy transformation of wastewater from a cooking tank. Refer to Figures 1 to 3 ; It includes a cooking tank 1. One end of the cooking water pipeline 2 is connected to the cooking tank 1 through a flange. The other end of the cooking water pipeline 2 is connected to one end of the first fluid pipeline of the plate heat exchanger 3. The other end of the first fluid pipeline of the plate heat exchanger 3 is connected to the first fluid channel of the DC horizontal air-air heat exchanger. One end of the second fluid pipeline of the plate heat exchanger 3 is connected to the water separation tank, and the other end enters the cooking tank after heat exchange. After the first fluid heat exchange of the DC horizontal air-air heat exchanger is completed, it enters the water seal tank. One end of the second fluid channel is connected to the heated natural wind 4, and the other end is connected to the DC cooling and drying device 5.

[0021] The water in the water separation tank at 32 / 34 is connected to the cooking tank 1 through the P32 water pump 7. The water outlet end of the cooking tank is successively connected to the temporary storage tank 10, the P45 cooking tank pump 11, the 81C plate heat exchanger 15, and the DC horizontal air-air heat exchanger 6 along the water flow direction. As Figure 3 shown.

[0022] In the prior art, the original wastewater from the cooking tank is directly discharged to the water seal tank after the 81C plate heat exchanger at about 60 degrees, resulting in waste of hot water energy.

[0023] The implementation content of this application: After the wastewater heated by the cooking tank passes through the DC horizontal air-air heat exchanger, the temperature of the eleventh layer of cold air in the DC is increased, and the steam consumption in the DC is reduced.

[0024] Implementation plan: By adding a DN100 pipeline to connect to the DC air-air heat exchanger (the original air-air heat exchanger was heated by steam, that is, changing the steam to wastewater), the water temperature is reduced from 60 degrees to 50 degrees, and the air temperature is increased from 28 degrees to 45 degrees. It is estimated that the heat absorbed is equivalent to 1.01 kg of soybeans per ton. Calculated according to an annual processing of 750,000 tons of soybeans, it is equivalent to 227,200 yuan per year.

[0025] It also includes a cyclone Shakeron dust collector. The air inlet 12 of the cyclone Shakeron dust collector is connected to the DC cooling and drying device through a pipeline. The solid discharge port 13 is arranged at the bottom of the cyclone Shakeron dust collector, and the air flow discharge port 14 is arranged at the top.

[0026] Multiple layers of partition plates are arranged in the cooking tank 1 to divide into multiple cooking spaces. At least one cooking space is connected to one end of the cooking water pipeline 2 through a flange.

[0027] There are a total of 9 groups inside the DC horizontal air-air heat exchanger to increase the heat exchange area.

[0028] During operation, the wastewater generated by the water distribution tank 9 enters the plate heat exchanger 3 through the P32 water pump 7, is heated up and then enters the cooking tank 1. After being heated in the cooking tank 1, it enters the temporary storage tank 10, and the high-temperature wastewater is pumped into the plate heat exchanger 3 again through the P45 cooking tank pump 11 for heat exchange. The water after heat exchange enters the first fluid channel of the DC horizontal air-air heat exchanger 6. The preheated wastewater exchanges heat with natural air in the DC horizontal air-air heat exchanger 6, so that the heated natural air enters the DC cooling and drying device 5 for drying processes or other processes that require hot air. The gas processed by the DC cooling and drying device 5 enters the cyclone dust collector for dust removal. The solid particulate matter is discharged through the solid discharge port 13 at the bottom of the cyclone dust collector, and the purified gas is discharged through the gas discharge port 14 at the top.

Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of this application and their equivalent technologies, the present invention is also intended to include these modifications and variations.
