Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a heat-insulating anaerobic tower used for producing distiller's grains biological feed. Background Art

[0002] Distillers' grains are a significant byproduct of the winemaking process. They are produced and discarded in large quantities, making them highly susceptible to spoilage. Distillers' grains are rich in nutrients, particularly soluble organic matter such as polysaccharides, proteins, and amino acids, offering advantages for resource utilization. For example, they can be dehydrated and dried to convert into organic fertilizer or feed. Fresh distillers' grains have a high moisture content, and currently, most distillers' grain-based biofeed production processes utilize drying equipment such as drum dryers and fluidized beds, often powered by steam or natural gas. These devices generate large amounts of hot water during operation, with outlet temperatures reaching 100°C, requiring cooling for proper discharge.

[0003] The IC anaerobic reactor is a highly efficient anaerobic treatment equipment that achieves highly efficient microbial contact and substrate conversion through internal circulation. It has the characteristics of high load and low footprint, making it very suitable for treating high-concentration organic wastewater. Therefore, it is widely used in the comprehensive treatment of brewing wastewater. At present, the temperature control of IC anaerobic devices is not flexible enough. When the environment is low, its anaerobic reaction activity is significantly reduced, and the treatment efficiency also decreases significantly, resulting in unstable operation. Traditional insulation methods often have high energy consumption and unstable insulation effects. Therefore, it is necessary to develop an efficient and energy-saving insulation structure for IC anaerobic devices. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of this application, "plurality" means two or more, unless otherwise specifically specified.

[0025] In the description of this application, the term "for example" is used to mean "used as an example, illustration or explanation". Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. In order to enable any person skilled in the art to implement and use the present invention, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present invention can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0026] In order to solve the problem that the IC anaerobic device (i.e. the anaerobic reactor body 1 in the text) in the distiller's grains bio-feed production plant is not flexible in temperature control, which significantly reduces the anaerobic reaction activity inside it and significantly reduces the treatment effect, see Figure 1This embodiment provides an insulated anaerobic tower for distiller's grains bio-feed production. The principle is to control the anaerobic fermentation temperature range within the IC anaerobic unit through insulation measures, thereby reducing the impact of cold environments on anaerobic water treatment. Specifically, the tower comprises an anaerobic reactor body 1, an inlet pipe 2, an outlet pipe 3, and an insulation pipe 4. The bottom of the anaerobic reactor body 1 is provided with an inlet pipe 2 connected to the circulating hot water outlet of the plant area, and an outlet pipe 3 connected to the circulating hot water inlet of the plant area. The plant area referred to here is the distiller's grains bio-feed production plant area, and the circulating hot water within the plant area can be hot water generated by various equipment during the production process within the plant area, such as drum dryers, fluidized bed drying equipment, and other drying equipment. The water inlet pipe 2 and the water outlet pipe 3 are both arranged at the bottom outside the anaerobic reactor body 1; the insulation pipe 4 is closely arranged along the outer wall of the anaerobic reactor body 1, and the water outlet of the water inlet pipe 2 is connected with the water inlet of the insulation pipe 4. The hot water in the insulation pipe 4 provides a heat source to the anaerobic reactor body 1. That is, in this way, the treated water of the anaerobic reactor body 1 is accelerated under the condition of heating, thereby improving the reaction efficiency. The water inlet of the outlet pipe 3 is connected with the water outlet of the insulation pipe 4, so that the heat exchange hot water after the work is completed is discharged through the outlet pipe.

[0027] In order to increase the heat exchange area and improve the heat exchange efficiency, the insulation pipe 4 includes a plurality of rising pipes 41 and a plurality of down-going pipes 42, so that the rising pipes 41 and the down-going pipes 42 are connected end to end and arranged along the height direction of the anaerobic reactor body 1. In this process, heat exchange is performed through the flow effect of water in the rising pipes 41 and the down-going pipes 42.

[0028] In order to improve the insulation effect and control heat loss, the insulation anaerobic tower of this embodiment further includes an insulation shell 5 provided on the outer surface of the anaerobic reactor body 1 , so that the insulation pipe 4 is located between the insulation shell 5 and the anaerobic reactor body 1 .

[0029] More specifically, the water inlet pipe 2 is provided with a hot water pressure pump 21 and a hot water inlet valve 22 connected in series. The hot water pressure pump 21 pumps hot water from outside the anaerobic reactor body 1 into the reactor body, and the hot water inlet valve 22 controls the flow rate of the hot water entering. Correspondingly, a hot water outlet valve 31 is provided on the water outlet pipe 3 to control the flow rate of the outlet water. To meet the temperature requirements within the anaerobic reactor body 1, the water inlet pipe 2 and the water outlet pipe 3 are both provided with thermometers and pressure gauges to monitor the temperature of the hot water entering the anaerobic reactor body 1 and the pressures of the water inlet pipe 2 and the water outlet pipe 3 in real time, so as to timely adjust the hot water inlet and outlet according to the hot water temperature. In the specific implementation process, the thermometer and the pressure gauge can be electrically connected to the controller.

[0030] An anaerobic tower gas-liquid separator 11 is provided on the top of the anaerobic reactor body 1, so that the biogas generated during the reaction in the anaerobic reactor body 1 is separated and collected through the anaerobic tower gas-liquid separator 11; and the treated water generated in the anaerobic reactor body 1 is discharged through the anaerobic tower outlet 12 provided on the upper part thereof. Specifically, the anaerobic tower outlet 12 is provided above the insulation pipe 4.

[0031] This embodiment utilizes circulating hot water in the biological feed plant area to provide the temperature required for anaerobic fermentation, without the need for additional heating, thereby reducing energy consumption while also improving anaerobic efficiency. There is no need to add additional water inlet, heating and other facilities, saving floor space, having excellent effects, strong practicality and easy promotion.

[0032] In this utility model:

[0033] The circulating hot water within the distiller's grains bio-feed production plant is connected to the hot water recycling pipeline within the plant through the water inlet pipe 2. Both pipes require insulation measures. The water inlet pipe 2 is equipped with a thermometer and pressure gauge and is connected to a hot water pressure pump 21. The outlet of the hot water pressure pump 21 is equipped with a hot water inlet valve 22. The circulating hot water is delivered by the hot water pressure pump 21 to an insulated pipe 4 that is closely attached to the outer wall of the anaerobic reactor. The insulated pipe 4 consists of several hot water risers 41 and hot water downcomers 42. The pipes are connected in a U-shaped pattern to maximize the contact time between the hot water and the reactor outer wall, improving the insulation and heating effect. An insulating outer shell is installed on the outside of the anaerobic reactor body 1, so that the insulated pipe 4 is located between the two to reduce heat loss.

[0034] It should be noted that, in the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.
