[0002] In the product production process of the canned food industry, there is a very important and key production process is thermal sterilization. Usually, a large amount of steam at a certain pressure is passed into the sterilizer for sterilization to ensure product quality and safety. The incoming cooling water takes away the heat in the pot to cool down. During the high-temperature sterilization process, a large amount of steam will be discharged from the sterilizing pot from the exhaust stage to before cooling, which not only causes the temperature of the surrounding environment to rise, but also generates a lot of noise, which is harmful to production On the other hand, the direct discharge of a large amount of steam makes the heat of the steam not fully utilized, resulting in a large amount of energy waste

Embodiment
[0021] like figure 1 As shown, the present invention includes a sterilizing pot 1, a sterilizing pot exhaust connecting pipe 12, a tubular heat exchanger 2, a condensed water collecting tank 3, a hot water buffer tank 4 and a plate heat exchanger 5, which are connected in sequence through pipes. The inlet and outlet of the heat exchanger 5 are respectively connected with the softening and deoxidizing equipment of the boiler room 6 to exchange heat with the treated water in the boiler room.
[0022] like figure 2 As shown in the schematic diagram of the system, there are a total of 6 sterilizers 1 arranged in parallel in the present invention, and each sterilizer 1 is provided with a plurality of steam vent holes 11 at the top, and each steam vent hole is respectively connected to a vertical steam vent pipe. The other end of the steam exhaust pipe is connected to the pipe wall of the sterilization pot exhaust connecting pipe 12, and the sterilizing pot exhaust connecting pipe...

The invention discloses a sterilizing pot exhaust heat energy recovering system in the can industry. The sterilizing pot exhaust heat energy recovering system comprises a sterilizing pot, a tubular heat exchanger, a condensate water collecting tank, a hot water buffering tank and a plate heat exchanger, wherein the sterilizing pot, the tubular heat exchanger, the condensate water collecting tank, the hot water buffering tank and the plate heat exchanger are sequentially connected through a pipeline. The sterilizing pot exhaust heat energy recovering system further comprises a sterilizing pot exhaust connecting tube arranged above the top of the sterilizing pot, and the sterilizing pot is connected to the sterilizing pot exhaust connecting tube through a plurality of steam releasing holes formed in the top of the sterilizing pot and is connected with the tubular heat exchanger through the sterilizing pot exhaust connecting tube. The sterilizing pot exhaust heat energy recovering system is used for recovering steam exhausted by the sterilizing pot, energy resources are saved, steam consumption in a factory is reduced, and besides noise is lowered.
Description
technical field [0001] The invention belongs to the field of production equipment in the canned product industry, in particular to a heat recovery system for a sterilizer. Background technique [0002] In the production process of the canned food industry, a very important and key production process is thermal sterilization. Usually, a large amount of steam with a certain pressure is passed into the sterilization pot for sterilization to ensure product quality and safety. The incoming cooling water takes away the heat in the pot for cooling and cooling. During the high-temperature sterilization process, a large amount of steam will be discharged from the sterilizer from the exhaust stage to the cooling, which not only causes the surrounding temperature to rise, but also generates a lot of noise, which is harmful to production. On the other hand, the direct discharge of a large amount of steam makes the heat of the steam not fully utilized, resulting in a large amount of ener...
