Description

Technical Field

[0001] The present invention relates to the field of comprehensive utilization of agricultural waste and bio-fermentation technology, and in particular to a method and device for preparing carbon dioxide gas fertilizer based on low-temperature fermentation of agricultural waste. The invention aims to achieve efficient resource utilization of agricultural waste through the integration of process flow and device, and to improve the crop growth environment or directly apply it as gas fertilizer by collecting carbon dioxide gas during the fermentation process, thereby promoting the development of green and energy-saving agriculture. Background Art

[0002] Currently, agricultural waste (such as rice husks and wheat husks) is commonly used as a source of biomass energy or organic fertilizer. However, the fermentation process to produce carbon dioxide often requires complex pretreatment procedures, such as crushing and adjusting the carbon-nitrogen ratio (C / N). This not only increases costs but also reduces production efficiency. With the increasing demand for environmentally friendly agricultural practices in recent years, the efficient use of these wastes has become a research hotspot.

[0003] To overcome these challenges, the industry generally adopts high-temperature fermentation (>50°C). While this method can complete the fermentation process in a shorter time, its efficiency is significantly reduced in winter or in colder regions. Furthermore, traditional fixed reactors cannot effectively guarantee an oxygen supply, requiring regular turning of the pile or membrane rupture to increase oxygen, which makes operation inconvenient and energy-intensive.

[0004] Existing high-temperature fermentation technology and equipment have obvious limitations. Especially under low-temperature conditions, the fermentation speed is slow or even stagnant; and due to the frequent need for manual intervention, the entire process becomes time-consuming and laborious. Summary of the Invention

[0005] The present invention discloses a method and apparatus for preparing carbon dioxide gas fertilizer based on low-temperature fermentation of agricultural waste. Pre-dried agricultural waste, such as rice husks and wheat husks, is mechanically compressed into blocks of uniform geometric shape and mass range, which are then packaged using biodegradable or plastic sealed packaging materials. The packaging is provided with a pre-set liquid inlet for injecting clean water and a low-temperature-resistant composite bacterial solution, as well as a pre-set liquid outlet for discharging excess liquid and fermentation products. This simplifies raw material pretreatment and efficiently controls liquid injection and gas discharge. After packaging, the blocks are precisely injected with clean water and bacterial solution via a metering pump and piping system, ensuring that the overall moisture content of the blocks meets preset requirements and that the composite bacterial solution is evenly distributed. Subsequently, the treated blocks are placed in a low-temperature fermentation environment strictly controlled by an automated temperature, humidity, and ventilation system. Through real-time monitoring and closed-loop regulation, environmental parameters are maintained within a range suitable for microbial activity and carbon dioxide production, thereby achieving efficient and stable fermentation results at relatively low temperatures. The carbon dioxide gas generated during the fermentation process is efficiently collected through the optimized drainage interface and gas-liquid separation unit. Ultimately, the gas fertilizer can be directly used to improve the crop growth environment or applied as gas fertilizer, which fully solves the defects of existing technologies such as low fermentation efficiency, complex process flow and high energy consumption under low temperature conditions.

[0006] In one aspect, a method for preparing carbon dioxide gas fertilizer based on low-temperature fermentation of agricultural waste comprises the following steps:

[0009] c) injecting an appropriate amount of clean water into the encapsulated block to reach a predetermined total water content, and simultaneously metering and inoculating a low-temperature-resistant composite bacterial solution to ensure that the composite bacterial solution is evenly distributed within the block;

[0010] d) placing the treated block in a controlled low-temperature fermentation environment, wherein the environment is maintained within a temperature range suitable for microbial activity and carbon dioxide production through temperature control, insulation measures, and real-time monitoring;

[0011] e) After the fermentation process reaches a predetermined stage, the carbon dioxide gas produced by the fermentation is directly used to improve the crop growth environment through a pre-set drainage interface or is collected and applied as gas fertilizer.

[0012] As a preferred solution, the parameters of each step are controlled as follows:

[0039] Secondly, by adopting biodegradable or plastic sealed packaging and pre-setting multi-channel liquid inlet and discharge interfaces on the packaging, the present invention achieves precise control of liquid injection and gas discharge, so that during the injection of clean water and composite bacterial liquid, the moisture distribution inside the material and the bacterial liquid inoculation level can be evenly regulated, thereby providing a uniform and stable reaction matrix for fermentation, which helps to improve the efficiency of carbon dioxide production.

[0040] Third, the present invention builds a controllable low-temperature fermentation environment and uses an automated temperature, humidity and ventilation system to achieve real-time monitoring and closed-loop control, maintaining the ambient temperature, humidity and airflow rate within a range suitable for microbial activity and CO2 generation, thereby ensuring that the fermentation process still exhibits efficient and stable gas production under low-temperature conditions, overcoming the defect of low efficiency of traditional high-temperature fermentation in cold environments.

[0041] Fourth, by integrating multi-channel fluid management and gas-liquid separation design, the present invention optimizes the separation and collection process of fermentation products, so that the liquid and carbon dioxide gas produced during the fermentation process can be quickly and effectively separated, thereby improving the purity and efficiency of carbon dioxide collection, while reducing the waste of resources and subsequent processing difficulties caused by residual liquid affecting gas collection.

[0042] Finally, the overall design of the invention adopts a modular and automated production process, which not only reduces dependence on manual operation and improves the stability and controllability of the system operation, but also is applicable to a variety of agricultural waste raw materials, has strong adaptability and promotion, and can provide economical and efficient gas fertilizer products for green agriculture, improve the crop growth environment, and achieve the dual benefits of energy saving and consumption reduction and resource recycling. DETAILED DESCRIPTION

[0043] The following examples are only used to illustrate the technical solution of the present invention more clearly, and are not intended to limit the scope of protection of the present invention.

[0044] According to one embodiment of the present invention, a method for preparing carbon dioxide gas fertilizer based on low-temperature fermentation of agricultural waste is provided. In this embodiment, rice husks and corn stalks are used as main raw materials, and agricultural waste is subjected to low-temperature fermentation to prepare carbon dioxide gas fertilizer.

[0045] First, rice husks and corn stalks collected from farmland are pre-processed and dried using electric heating or natural air drying to reduce the moisture content to 10% to 15%. The dried agricultural waste is then mechanically compressed into standard blocks using a compressor and forming molds on the production line. The blocks weigh between 3 and 8 kilograms and exhibit a uniform geometric shape (such as a cylinder or rectangular parallelepiped). This step is automatically transported to the next process using an auxiliary conveyor device, ensuring consistent block specifications and providing a stable substrate for subsequent processing.

[0046] Next, in the packaging process, the block is sealed and packaged with a biodegradable plastic film. The packaging material is made of a biodegradable film with a thickness of 0.05 to 0.1 mm, excellent tensile strength and puncture resistance, which not only meets the physical isolation requirements but also meets the environmental protection requirements. During the packaging process, a liquid inlet interface (about 2 to 5 mm in diameter) with an automatic sealing valve and a liquid discharge interface (about 3 to 8 mm in diameter) with an anti-backflow design are preset on the film. Among them, the positioning of each interface adopts a multi-channel layout design to ensure good fluid balance during liquid injection and gas discharge, and to prevent external contamination while achieving rapid exchange. The packaging unit can be operated by a drum-type automatic packaging machine, or a semi-automatic control method can be adopted according to the production scale.

[0047] During the injection step, a metering pump and piping system are used to inject clean water and low-temperature-resistant composite bacterial solution into the encapsulated block. The amount of clean water injected is strictly controlled so that the overall moisture content of the block is stably adjusted to 65% to 70%. At the same time, the metering equipment injects the pre-configured composite bacterial solution (wherein the composite bacterial solution contains 40% Candida, 30% Streptomyces, 20% lactic acid bacteria and 10% humus carrier by mass ratio) evenly into the block according to the principle of injecting 50 to 100 ml of composite bacterial solution per kilogram of dry matter. During injection, a segmented injection or circulating homogenization process can be adopted to ensure that the bacterial solution is evenly distributed throughout the matrix, thereby providing stable microbial activity. It is worth noting that in different regions or raw material conditions, the ratio and injection amount of the bacterial solution can be adjusted and optimized accordingly according to the actual process requirements.

[0048] Subsequently, the processed encapsulated blocks are transported to a controllable low-temperature fermentation environment. This environment is usually set up in a greenhouse or shed, and the ambient temperature, relative humidity and air flow rate are monitored and adjusted in real time through an integrated automated temperature, humidity and ventilation control system. In the control system, temperature sensors, humidity sensors and flow rate sensors form a sensor network to ensure that the daytime temperature is maintained between 20°C and 25°C, the nighttime temperature is not lower than 8°C, and the relative humidity is maintained in the range of 60% to 80%. At the same time, the ventilation equipment adjusts the air circulation according to the preset plan. During the fermentation process, through the closed-loop feedback of the control system, a small amount of low-temperature-resistant composite bacterial solution or clean water can be added in time according to the real-time monitoring data to ensure that the entire fermentation process remains in the optimal state of microbial activity and promotes the continuous and stable production of carbon dioxide.

[0049] The fermentation cycle is usually limited to 5 to 10 days. When the environmental control system detects that the carbon dioxide production reaches the predetermined agricultural application standard, the gas collection program is immediately started through the pre-set drainage interface and the built-in gas-liquid separation unit. The gas-liquid separation unit uses a diversion channel and a separator design to achieve rapid separation of liquid waste and the generated carbon dioxide gas. The liquid part is directed to the waste liquid recovery system, while the pure carbon dioxide gas is collected to the gas output device through a dedicated pipeline. The collected carbon dioxide gas can be directly used to increase the yield of greenhouse crops, improve the crop growth environment, or be applied as gas fertilizer to the field, thereby reducing the use of chemical fertilizers and promoting green agriculture. Of course, when the fermentation environment needs to be adjusted with gas fertilizer, the carbon dioxide gas can be directly released into the air through the drainage interface or a separately designed exhaust interface to improve the growth environment of crops grown in the greenhouse.

[0050] According to another embodiment of the present invention, a carbon dioxide gas fertilizer preparation device based on low-temperature fermentation of agricultural waste is provided, the structure of which includes a raw material processing unit, a packaging unit, a liquid injection unit, an environmental control unit and a gas collection unit.

[0051] In the raw material processing unit, a compressor, forming molds, and auxiliary conveying devices are used to compress the dried agricultural waste into blocks of uniform geometry and quality. The unit is equipped with automatic detection devices that monitor the weight and shape of the blocks online to ensure that product specifications meet process requirements.

[0052] The packaging unit, comprised of an automated packaging machine, seals the blocks with pre-applied biodegradable plastic film. During the packaging process, the machine simultaneously installs a liquid inlet port with an automatic sealing valve and a drain port with backflow prevention on the packaging material. The ports utilize a multi-channel design to optimize liquid injection and gas discharge. Internally positioned precision molds ensure that the angle and number of ports meet design requirements, while also guaranteeing the packaging material's stability and tensile strength throughout the fermentation cycle.

[0053] The injection unit injects clean water and a cryogenically resistant composite bacterial solution into the encapsulated blocks via a metering pump and precision piping system. This system incorporates an automated metering module that precisely measures the required volumes of clean water and bacterial solution, ensuring a uniform moisture content of 65% to 70% for each block. The bacterial solution inoculation rate is strictly adhered to at 50 to 100 ml per kilogram of dry matter. A homogenizing and mixing device ensures even distribution of the injected liquid throughout the block, enhancing the integration of the bacterial solution with the waste matrix.

[0054] The environmental control unit is equipped with an automatic temperature and humidity control system and ventilation control. A sensor network monitors various environmental parameters within the greenhouse or shed in real time, providing feedback to a central controller. Through closed-loop control, the unit automatically adjusts heating, insulation, and ventilation equipment to maintain a temperature of 20°C to 25°C during the day and no lower than 8°C at night, while maintaining humidity within the optimal range of 60% to 80%. To adapt to different time periods and fermentation stages, the unit also features segmented monitoring, enabling dynamic adjustment of the environmental conditions within certain encapsulated blocks to ensure overall fermentation uniformity and efficiency.

[0055] The gas collection unit consists of a gas-liquid separation device housed within the packaging unit, and an independent external gas collection pipeline and output device. The gas-liquid separation device utilizes a flow channel and separator, designed to effectively separate the liquid and carbon dioxide gas that emerge from the drain port. The liquid portion is transported through the flow channel to the waste liquid recovery system, while the carbon dioxide gas is quickly transported to the gas output device via a dedicated pipeline. After pressure regulation and purification, it can be directly used to increase greenhouse production or applied as gas fertilizer.

[0056] Furthermore, to enhance the overall automation level of the device, all functional units are integrated and linked through a central control module and data bus, enabling intelligent monitoring and closed-loop regulation throughout the entire process. Based on preset process parameters and real-time data, the control module automatically regulates liquid injection, environmental parameter adjustment, and gas collection through the central processor. Remote monitoring and data logging are also supported, ensuring stable operation under diverse environmental conditions. This fully automated, modular design for the production of CO2 fertilizer from low-temperature fermentation of agricultural waste is achieved.

[0057] In the above-mentioned embodiments, the parameters, equipment structure, and operating methods of each unit can be appropriately adjusted according to the specific application scenario and local conditions. For example, in terms of raw material selection, any one or a combination of rice husks, wheat husks, corn stalks, cottonseed hulls, or bean pods can be used; other environmentally friendly sealing materials can also be used for packaging materials; and in terms of environmental control strategies, the temperature and humidity control scheme can be optimized according to seasonal and climatic conditions. All alternative solutions are within the scope of protection of the technical solution of the present invention, which aims to provide comprehensive technical support for the production of efficient, stable, energy-saving, and environmentally friendly low-temperature fermentation carbon dioxide gas fertilizer.

[0058] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
