Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically to a device for purifying and reusing saccharification condensate. Background Technology

[0002] Currently, most of the secondary steam heat from the boiling kettles in the saccharification workshop of beer production companies has been recovered and stored in thermal energy storage tanks for use in the sterilization machines or bottle washing machines in the packaging workshop. However, the condensate produced by the secondary steam contains impurities and cannot be directly recycled. After cooling, the condensate is discharged to a wastewater treatment plant through sewage pipes. But this condensate remains at a very high temperature (50-70℃), and direct discharge to the wastewater treatment plant not only increases the burden on wastewater treatment but also fails to effectively utilize its heat content.

[0003] In addition, the condensate from the secondary steam generated by the boiling pot contains impurities such as sugar, which can easily produce an odor and cannot be directly recycled. Utility Model Content

[0004] This invention provides a device for purifying and reusing condensate from saccharification processes. By adding a biochemical treatment device, the device decomposes the sugar and organic matter in the condenser, while simultaneously solving the problem of continuous sterilization.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for purifying and reusing saccharification condensate, comprising a plate heat exchanger, a biochemical treatment device, an activated carbon filter tank, a sterilization tank, and a feed water storage tank; the plate heat exchanger is provided with a usage-side inlet, a usage-side outlet, a condensate inlet, and a condensate outlet; the usage-side inlet and outlet are respectively connected to the feed water storage tank via pipelines; the condensate inlet is equipped with a first circulation pump, the inlet of which is connected to the secondary steam condensate from the boiling pot via a pipeline; the secondary steam condensate heats the usage-side water in the plate heat exchanger and is then discharged from the condensate outlet; the inlet of the biochemical treatment device is connected to the condensate outlet, the inlet of the activated carbon filter tank is connected to the outlet of the biochemical treatment device, and the inlet of the sterilization tank is connected to the outlet of the activated carbon filter tank.

[0006] Furthermore, the water inlet on the user side is connected to the bottom of the feeding water storage tank via a pipeline, the water outlet on the user side is connected to the top of the feeding water storage tank via a pipeline, and a second circulation pump is installed on the pipeline between the water inlet on the user side and the feeding water storage tank.

[0007] Furthermore, an ultraviolet germicidal lamp is installed inside the sterilization tank.

[0008] Furthermore, it also includes a cleaning mechanism, which includes a drive motor, a transmission screw, and a scraper. The drive motor is mounted on the outside of the sterilization tank via a motor mount. The output shaft of the drive motor extends into the sterilization tank and is coaxially fixed with the transmission screw. The output shaft of the drive motor is rotatably connected to the sterilization tank in a sealed manner. The end of the transmission screw away from the drive motor is rotatably connected to an assembly seat inside the sterilization tank. The scraper is provided with a through hole adapted to the ultraviolet sterilization lamp and a threaded hole for threaded transmission with the transmission screw. A brush is provided in the through hole.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] The device for purifying and reusing saccharification condensate disclosed in this application first uses a plate heat exchanger to exchange heat between the condensate and the feed water that needs to be heated. The cooled condensate then sequentially enters a biochemical treatment device, an activated carbon filter tank, and a sterilization tank. The biochemical treatment device is used to decompose sugars and other organic matter and reduce the COD in the condensate. The activated carbon in the activated carbon filter tank removes the odor from the condensate. The sterilization tank solves the problem of continuous sterilization. The treated condensate can be used for initial washing.

[0011] As can be seen from the above, the technical solution disclosed in this application not only saves the amount of steam used for heating the feed water, but also allows the condensate to be recycled and reused, thereby reducing the water consumption in beer production.

[0020] Please see Figure 1-5 This utility model provides a device for purifying and reusing saccharification condensate, including a plate heat exchanger 10, a biochemical treatment device 20, an activated carbon filter tank 30, a sterilization tank 40, a cleaning mechanism, and a feed water storage tank 60.

[0021] The plate heat exchanger 10 is equipped with a user-side water inlet, a user-side drain, a condensate inlet, and a condensate drain. The user-side water inlet and drain are connected to the feed water storage tank 60 via pipelines. Specifically, the user-side water inlet is connected to the bottom of the feed water storage tank 60 via a pipeline, and the user-side drain is connected to the top of the feed water storage tank 60 via a pipeline. A second circulation pump 11 is installed on the pipeline between the user-side water inlet and the feed water storage tank 60. A first circulation pump 12 is installed at the condensate inlet. The inlet of the first circulation pump 12 is connected to the secondary steam condensate from the boiling pot via a pipeline. The secondary steam condensate heats the user-side water within the plate heat exchanger 10 before being discharged from the condensate drain.

[0022] The inlet of the biochemical treatment equipment 20 is connected to the condensate drain outlet.

[0023] The inlet of the activated carbon filter tank 30 is connected to the outlet of the biochemical treatment equipment 20.

[0024] The water inlet of the sterilization tank 40 is connected to the drain of the activated carbon filter tank 30. An ultraviolet sterilization lamp 41 is installed inside the sterilization tank 40. In this embodiment, there are two ultraviolet sterilization lamps 41. An assembly base 42 is installed inside the sterilization tank 40.

[0025] The cleaning mechanism includes a drive motor 51, a transmission screw 52, ​​and a scraper 53. The drive motor 51 is mounted on the outside of the sterilization tank 40 via a motor base 54. The output shaft of the drive motor 51 extends into the sterilization tank 40 and is coaxially fixed with the transmission screw 52. The output shaft of the drive motor 51 is rotatably connected to the sterilization tank 40 in a sealed manner. The end of the transmission screw 52 away from the drive motor 51 is rotatably connected to the mounting base 42. The scraper 53 is provided with a through hole adapted to the ultraviolet sterilization lamp 41 and a screw hole 55 for threaded transmission with the transmission screw. A brush 56 is provided in the through hole.

[0026] The working principle of this utility model is as follows:

[0027] The secondary steam condensate from the boiling pot enters the condensate inlet via the first circulation pump 12. After heating the water on the user side in the plate heat exchanger 10, it is discharged from the condensate drain. The discharged condensate is then purified by passing through the biochemical treatment equipment 20, the activated carbon filter tank 30, and the sterilization tank 40 in sequence.

[0028] During prolonged use, dust may accumulate on the outside of the UV germicidal lamp 41, affecting the sterilization effect. Regularly activate the cleaning mechanism, and the drive motor 51 will move the scraper 53 through the transmission screw 52, ​​while the brush 56 will scrape away the dirt on the outside of the UV germicidal lamp 41.
