Description

Technical Field

[0001] This application relates to microbial fermentation technology, and more particularly to an air handling device for a fermenter. Background Technology

[0002] During microbial fermentation, sterile air needs to be introduced into the fermenter to provide a sterile aerobic fermentation environment for microbial fermentation and to ensure dissolved oxygen levels.

[0003] Currently, the sterile air used in microbial fermentation is obtained by filtering and sterilizing compressed air supplied by an air compressor. After filtration, the compressed air is typically sterilized using ultraviolet (UV) lamps. However, UV lamps produce ozone during the sterilization process, and this ozone can enter the fermentation tank along with the sterilized air. If the ozone concentration inside the fermentation tank is too high, it will affect the microbial fermentation process. Utility Model Content

[0011] Optionally, each vertical section of the heating cavity is provided with multiple partitions distributed vertically, which divide the vertical section into a serpentine channel.

[0019] Compared with the prior art, the beneficial effects of this application are as follows:

[0020] The air handling unit for fermenters provided in this application comprises a heating chamber and a cooling chamber. The heating chamber has an air inlet and an exhaust outlet, and a heating device is installed inside the heating chamber. The upper end of the cooling chamber is connected to the air inlet, and a heat exchange tube connected to the exhaust outlet is installed inside the cooling chamber, extending out of the cooling chamber.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0028] like Figures 1-4 As shown:

[0029] An embodiment of this application provides an air treatment device for a fermenter, including a heating chamber 1 and a cooling chamber 2. The heating chamber 1 is provided with an air inlet 201 and an exhaust outlet 202, and a heating device 3 is provided inside the heating chamber 1.

[0030] The upper end of the cooling chamber 2 is connected to the air inlet 201.

[0031] The cooling chamber 2 is equipped with a heat exchange tube 4 connected to the exhaust port 202, and the heat exchange tube 4 extends out of the cooling chamber 2.

[0032] The lower end of the cooling chamber 2 is equipped with a filter structure 5 for filtering air.

[0033] In this embodiment, the extension end of the heat exchange tube 4 is connected to a sterile air storage tank for storing sterile air. The sterile air storage tank is connected to the air inlet 201 of the fermenter via a delivery pipeline. The filter structure 5 is connected to an air compressor via a gas delivery pipeline.

[0034] In use, the compressed air from the air compressor first enters the filter structure 5 for filtration, then enters the cooling chamber 2, and from the cooling chamber 2 into the heating chamber 1. The heating device 3 heats and sterilizes the air in the heating chamber 1 to form sterile air. Then, the heated sterile air enters the heat exchange tube 4 to exchange heat with the low-temperature air in the cooling chamber 2. The low-temperature air absorbs the heat from the sterile air, which preheats the low-temperature air and cools the sterile air. Finally, the cooled sterile air enters the sterile air storage tank from the heat exchange tube 4 for storage. The sterile air in the sterile air storage tank enters the fermenter through the delivery pipeline to provide sterile air for the fermenter.

[0035] The air handling unit for the fermenter provided in this embodiment includes a heating chamber 1 and a cooling chamber 2. The heating chamber 1 has an air inlet 201 and an exhaust outlet 202. A heating device 3 is installed inside the heating chamber 1. The upper end of the cooling chamber 2 is connected to the air inlet 201. A heat exchange pipe 4 connected to the exhaust outlet 202 is installed inside the cooling chamber 2 and extends out of the cooling chamber 2. A filter structure 5 for filtering air is installed at the lower end of the cooling chamber 2. This allows the air to be sterilized by heating it during use, ensuring the sterilization effect without producing ozone. This solves the problem of ozone entering the fermenter and affecting microbial fermentation. Furthermore, it can preheat the air to be sterilized, thereby reducing the energy consumption of the heating device 3 and achieving energy-saving effects.

[0036] In some embodiments of this application, the cooling cavity 2 is a ring structure, and the cooling cavity 2 is sleeved and fixed on the outside of the heating cavity 1, thereby achieving the effect of compact structure and small space occupation.

[0037] In this embodiment, the inner wall of the cooling cavity 2 coincides with the outer wall of the heating cavity 1, and the upper end of the cooling cavity 2 is connected to the air inlet 201.

[0038] In some embodiments of this application, the heating device 3 employs an electric heating plate, which is fixed inside the heating chamber 1 and divides the heating chamber 1 into a U-shaped cavity structure. This allows air to flow along the U-shaped cavity structure after entering the heating chamber 1, thereby prolonging the air's flow time within the heating chamber 1 and improving the heating effect. An air inlet 201 is located at one end of a vertical section of the heating chamber 1, and an exhaust port 202 is located at the other end of a vertical section of the heating chamber 1.

[0039] In some embodiments of this application, each vertical section of the heating chamber 1 is provided with a plurality of vertically distributed baffles 6, which divide the vertical section into a serpentine channel to further increase the air flow time in the heating chamber 1.

[0040] In some embodiments of this application, the heat exchange tube 4 has an inverted conical spiral structure.

[0041] In this embodiment, the heat exchange tube 4 with its inverted conical spiral structure can not only prolong the flow time of sterile air in the cooling chamber 2, but also improve the contact effect between the heat exchange tube 4 and the low-temperature air, thereby improving the cooling effect of the sterile air.

[0042] In some embodiments of this application, the inner wall of the heating chamber 1 is provided with a heat insulation layer (not shown in the figure) to prevent the heat in the heating chamber 1 from affecting the cooling effect of the sterile air in the cooling chamber 2. The inner wall of the cooling chamber 2 is provided with a heat insulation layer (not shown in the figure) to prevent heat loss.

[0043] In some embodiments of this application, the filter structure 5 includes a filter cavity 501, an air filter layer 502 is provided inside the filter cavity 501, and an air inlet pipe 503 located below the air filter layer 502 is connected to the filter cavity 501. The air inlet pipe 503 is connected to an air compressor through an air supply pipeline.

[0044] The filter chamber 501 is connected to the lower end of the cooling chamber 2 and is sealed and fixedly connected.

[0045] In this embodiment, the air filter layer 502 is existing technology and will not be described in detail.

[0046] During use, the air supplied by the air compressor first enters the filter chamber 501 through the air inlet pipe 503, and then the air filter layer 502 filters the air. The filtered air then enters the heating chamber 1 through the cooling chamber 2 for sterilization.

[0047] In some embodiments of this application, a sealing cover 504 is detachably fixed to the lower end of the filter chamber 501, and a mounting base 505 is fixed to the upper end of the sealing cover 504. The air filter layer 502 is detachably fixed to the mounting base 505.

[0048] Specifically, the sealing cover 504 is detachably connected to the lower end of the filter chamber 501 via a flange structure. The mounting base 505 includes a support rod 506 and a support plate 507. The lower end of the support rod 506 is fixedly connected to the sealing cover 504. A support mesh is sleeved and fixed on the upper part of the support rod 506. A pressure plate 508 is threadedly connected to the upper end of the support rod 506. Both the support plate 507 and the pressure plate 508 are mesh structures. The air filter layer 502 can be sleeved on the support rod 506, and the air filter mesh can be tightly pressed between the support plate 507 and the pressure plate 508.

[0049] Furthermore, the outer diameters of the support plate 507 and the pressure plate 508 are both smaller than the outer diameter of the air filter layer 502, and the outer diameter of the air filter layer 502 can tightly press against the inner wall of the filter cavity 501.

[0050] When in use, after removing the sealing cover 504 from the filter chamber 501, pull down the sealing cover 504 to remove the air filter layer 502 from the filter chamber 501. Then remove the pressure plate 508 to replace the air filter layer 502, which facilitates the subsequent disassembly and replacement of the air filter layer 502.

[0051] In some embodiments of this application, the sealing cap 504 is a groove structure with an open top, so that impurities intercepted by the air filter layer 502 can settle in the groove of the sealing cap 504, thereby facilitating the collection of these impurities.

[0052] In some embodiments of this application, a bracket 7 is fixedly connected to the outer wall of the heating cavity 1 to support the cooling cavity 2.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
