Description

Technical Field

[0001] This utility model relates to the field of microbial fermentation technology, and in particular to an exhaust device for a microbial fermenter. Background Technology

[0002] Microbial fermentation refers to the process by which microorganisms, under suitable conditions, transform raw materials into products needed by humans through specific metabolic pathways. Microbial fermentation tanks are common storage containers for microbial fermentation. There are many types of microbial fermentation tanks on the market, and most of them are equipped with exhaust devices to facilitate the discharge of gases produced during microbial fermentation.

[0003] Currently, exhaust gas treatment technology for microbial fermenters mainly involves collecting, filtering, and treating the waste gas emitted from the fermenter's exhaust port to meet environmental emission requirements. The exhaust gas treatment process of microbial fermenters generates a large amount of heat, but current technologies do not utilize this heat; instead, it is directly released into the atmosphere, resulting in energy waste. Furthermore, in the waste gas filtration process, existing technologies typically only use two filter layers, leading to poor solid-gas separation and a tendency for pipe blockage.

The inlet is located at the top of the fermenter body, the outlet is located at the bottom of the fermenter body, and the support is fixedly connected to the bottom of the surface of the fermenter body.

One end of the primary filter layer, the secondary filter layer and the tertiary filter layer are fixed on the guide column, and the other end is fixed on the inner wall of the cylinder. A turbulent channel is formed between adjacent filter layers.

[0007] As a further description of this utility model, the integrated thermoelectric module includes a cold end and a hot end. The hot end is in contact with the liquid storage tank through a heat-conducting plate, and the cold end is connected to a temperature difference generating circuit. The temperature difference between the cold and hot ends forms an electric current, which converts thermal energy into electrical energy.

A detailed view of the filter component 2 is shown below. Figure 2 As shown;

[0028] The exhaust component 3 includes a first side plate 31, a second side plate 32, a third side plate 33, and a fourth side plate 34. The fourth side plate 34 is connected to the exhaust pipe b 28. A liquid storage tank 35 is provided on the upper part of the first side plate 31, and the liquid storage tank 35 is fixedly connected to the first side plate 31. An integrated thermoelectric module is fixed between the first side plate 31 and the third side plate 33. The integrated thermoelectric module includes a ceramic plate 36, a semiconductor 37, a heat-conducting sheet 38, and an energy storage battery 39. The ceramic plate 36 is divided into upper and lower layers. The lower ceramic plate is located slightly above the middle of the exhaust component 3. The heat-conducting sheet 38 and the semiconductor 37 are arranged sequentially from the lower ceramic plate to the upper ceramic plate. The energy storage battery 39 is fixed on the fourth side plate 34, located above the ceramic plate 36. A fan 310 is fixed on the second side plate 32, located between the liquid storage tank 35 and the ceramic plate 36. The air outlet of the fan 310 is connected to an air outlet pipe 311. A detailed view of the exhaust component 3 is shown below. Figure 1 As shown.

[0029] In this embodiment, the integrated thermoelectric module includes a hot end and a cold end. The hot end is in contact with the liquid storage tank 35 through a heat-conducting plate 38, and the cold end is connected to a temperature difference generating circuit. The temperature difference between the hot and cold ends forms a current, which converts thermal energy into electrical energy.

[0030] In this embodiment, the output terminal of the integrated thermoelectric module circuit is connected to the energy storage battery 39, which can store the recovered electrical energy for the self-powering of the device system.

[0031] In this embodiment, a plurality of filter holes 27 are uniformly provided on the filter layer. The filter holes 27 on different filter layers have different pore diameters. The gradually decreasing filter holes 27 can effectively separate microorganisms and impurities in the exhaust gas and prevent pipe blockage.

[0032] In this embodiment, the liquid storage tank 35 is made of a high-temperature resistant and corrosion-resistant alloy, which improves the durability of the liquid storage tank.

[0033] In this embodiment, a catalytic coating is provided on the inner wall of the liquid storage tank 35. The catalytic coating can accelerate the chemical reaction between the waste gas and the solution in the liquid storage tank 35 and improve the treatment efficiency.

[0036] In this embodiment, the primary filter layer 23, the secondary filter layer 24, and the tertiary filter layer 25 are all made of corrosion-resistant materials. The use of corrosion-resistant materials extends the service life of the filter layers and reduces maintenance costs.

[0037] The working principle of this utility model is as follows: During use, the material is introduced into the fermentation tank 1 through the feed inlet 11, and then the feed inlet 11 is closed for fermentation. Gas is generated during fermentation, leading to increased pressure within the fermentation tank 1. When the pressure reaches a certain value, the gas enters the filter element 2 through the exhaust pipe a 21. The gas passes sequentially through the third-stage filter layer 25, the second-stage filter layer 24, and the first-stage filter layer 23. The pore size of the multi-layer spiral filter layer decreases progressively, ensuring thorough filtration and separation of the gas. The filtered gas then passes through the exhaust pipe b. 28 enters the exhaust component 3 and then reacts chemically with the solution in the storage tank 35, generating a large amount of heat. This heat and the heat generated during fermentation in the fermentation tank 1 are integrated through the heat-conducting plate 38, forming a temperature difference with the cold end of the integrated thermoelectric module. When the temperature difference reaches a certain value, a current will be generated in the temperature difference circuit, converting the heat energy generated by the waste heat into electrical energy and storing it in the storage battery 39. The controller 312 of the device selects the electrical energy in the storage battery 39 for operation according to the internal algorithm. The waste gas after the reaction in the storage tank 35 is discharged from the device along the exhaust pipe 311, so that the pressure in the fermentation tank 1 returns to normal.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
