Description

Technical Field

[0001] This application relates to the technical field of composting equipment, and particularly relates to an upgrading method for a tank (bin) type fermentation composting system. Background Art

[0002] The aerobic fermentation technology refers to the process in which aerobic microorganisms such as bacteria, fungi, and actinomycetes utilize oxygen through their own life metabolism activities under suitable artificial control conditions, oxidize, absorb, and decompose easily degradable organic substances to form humus and release energy. The heat released is used to remove moisture and kill pathogens to achieve the reduction and harmless treatment of organic waste. After development, various processes such as tank type fermentation, windrow type fermentation, tower type fermentation, and integrated fermentation equipment have emerged. Among them, the tank (bin) type fermentation is the most common disposal process due to its high treatment capacity and low basic investment. However, a high treatment capacity means a large compost pile, which has problems such as slow temperature rise, high oxygen demand and heat release per batch. Usually, it is necessary to install a turning machine to increase the turning frequency or lay aeration pipes to increase the aeration volume to maintain the optimal fermentation conditions. However, excessive turning times and aeration volumes will significantly increase the operating cost, and are also prone to problems such as uneven fermentation, excessive moisture loss from the compost pile, and heat dissipation, resulting in poor fermentation effect.

[0038] The following refers to Figure 1 Describe an upgrading method for a trough (bin) type fermentation composting system in an embodiment of the present application.

[0039] An upgrading method for a trough (bin) type fermentation composting system in an embodiment of the present application includes the following steps:

[0040] Step S1: Divide a trough (bin) type fermentation composting system into multiple fermentation troughs 100, and arrange the multiple fermentation troughs 100 side by side.

[0041] Step S2: A fermentation area 110 for accommodating a miniaturized compost heap is formed in each fermentation trough 100.

[0042] Step S3: Start feeding the material from the discharge end of the fermentation trough 100 into the fermentation area 110.

[0043] Step S4: The initial feeding is located in the middle front part of the fermentation trough 100, and the material is fed into the fermentation area 110 in sequence at time intervals.

[0044] A method for upgrading and transforming a trough (warehouse) type fermentation and composting system in an embodiment of the present application is provided, by dividing the trough (warehouse) type fermentation and composting system into a plurality of fermentation tanks 100, the fermentation tanks 100 are divided into a plurality of fermentation areas 110, and the fermentation areas 110 are provided with materials at time intervals, and the fermentation areas 110 accommodate the miniaturized piles, which can reduce the volume of a single pile building; through the mode of continuous pile building at time intervals, the heat generated by fermentation can be fully utilized to achieve rapid heating of the subsequent piles, and at the same time, the subsequent piles can enter the high temperature period to dry the previous piles in the cooling period, quickly remove moisture, shorten the fermentation and composting cycle, save energy consumption, and reduce operating costs. It should be noted that the moisture content of the material of the miniaturized pile is reduced to about 40% on the 12th day of fermentation, while conventional composting requires until the 21st day for the moisture content of the pile to be reduced to about 40%. In the aerobic composting process, a moisture content of about 40% is usually regarded as a sign of the end of a fermentation, and the material undergoes an aging stage. Therefore, by reducing the volume of a single pile construction in the present application and continuously building the pile at time intervals, moisture can be quickly removed, the fermentation and composting cycle can be shortened, energy consumption can be saved, and operating costs can be reduced.

[0045] It should be noted that, in some embodiments, a retaining wall is provided between the multiple fermentation tanks 100 of the trough (warehouse) type fermentation composting system, and the retaining wall is used to divide the system. In some other embodiments, the multiple fermentation tanks 100 of the trough (warehouse) type fermentation composting system are connected, and retaining walls are not provided between the multiple fermentation tanks 100. The trough (warehouse) type fermentation composting system can also be divided into multiple fermentation tanks 100 for distribution.

[0046] Specifically, in some embodiments, the materials are fed into the fermentation area 110 sequentially at time intervals, and the time intervals are one to three days.

[0047] According to some embodiments of the present application, after materials are distributed into the fermentation area 110 in sequence at time intervals, the fermentation area 110 is aerated through a modular aeration pipe network.

[0048] According to some embodiments of the present application, a plurality of modular aeration pipe networks are provided, and each modular aeration pipe network performs aeration treatment according to the feeding time of each miniaturized pile. According to the feeding time of the miniaturized pile, the fermentation stage of the miniaturized pile can be determined, and the ventilation rate is adjusted specifically according to the fermentation stage of the miniaturized pile, thereby avoiding the problems of slow heating, high energy consumption, high operating cost, etc. of the large pile, thereby achieving energy saving.

[0049] According to some embodiments of the present application, when the core temperature of the miniaturized stack is greater than or equal to 65°C, the ventilation rate of the modular aeration network is set to 0.1-0.2m3 / (min.m3); when the core temperature of the miniaturized stack is less than or equal to 60°C, the ventilation rate of the modular aeration network is set to 0.05-0.1m3 / (min.m3); when the core temperature of the miniaturized stack is less than or equal to 45°C, the modular aeration network stops ventilation. Specifically, the modular aeration pipe network is connected to a blower device, and the blower device 200 includes a blower and a blower control module. After the miniaturized pile is placed in the fermentation area 110, a temperature sensor is arranged in the middle of the miniaturized pile, and the depth of the temperature sensor in the miniaturized pile is greater than 1m. The temperature sensor is electrically connected to the blower control module. When the temperature sensor senses that the temperature of the miniaturized pile reaches 65°C or above, the temperature sensor sends a signal to the blower control module, and the blower control module controls the ventilation rate of the blower to 0.1-0.2m3 / (min.m3). When the temperature sensor senses that the temperature of the miniaturized pile drops to 60°C or below, the temperature sensor sends a signal to the blower control module, and the blower control module controls the ventilation rate of the blower to 0.05-0.1m3 / (min.m3). When the temperature sensor senses that the temperature of the miniaturized pile drops to 45°C or below, the temperature sensor sends a signal to the blower control module, and the blower control module controls the blower to stop ventilation. The temperature of the miniaturized pile is sensed by a temperature sensor, and the ventilation rate is adjusted according to the fermentation stage of the miniaturized pile, thus avoiding the problems of slow heating, high energy consumption, and high operating costs of large piles, thereby saving energy.

[0050] According to some embodiments of the present application, the length of a single cloth is between 10% and 20% of the length of the fermentation tank. A plurality of fermentation areas 110 are formed in the fermentation tank, and the length of a single cloth is between 10% and 20% of the length of the fermentation tank 100, that is, the length of a single cloth is one-fifth to one-tenth of the length of the fermentation tank 100. In some embodiments, five fermentation areas 110 are provided, and the length of the fermentation area 110 is one-fifth of the length of the fermentation tank 100. In some other embodiments, ten fermentation areas 110 are provided, and the length of the fermentation area 110 is one-tenth of the length of the fermentation tank 100.

[0051] According to some embodiments of the present application, the width of a single cloth feeding is at least the same as the width of one fermentation tank 100. A tank (bin) type fermentation composting system is divided into multiple fermentation tanks 100. The setting of multiple fermentation tanks 100 can reduce the volume of a single compost pile and accommodate a small-sized compost pile. It should be noted that the width of a single cloth feeding is at least the same as the width of one fermentation tank 100, which can reduce the volume of a single compost pile and make full use of the space in the fermentation tank 100. It can be understood that in some embodiments, a tank (bin) type fermentation composting system is divided into four fermentation tanks 100, and the width of a single cloth feeding is the same as the width of the four fermentation tanks 100, which can cloth feed the four fermentation tanks 100 simultaneously, reduce the volume of a single compost pile, and improve the cloth feeding efficiency.

[0052] According to some embodiments of the present application, there are multiple modular aeration pipe networks. Each modular aeration pipe network includes a main pipe 310 and multiple branch pipes 210. One end of the main pipe 310 is connected to a blower device. The other end of the main pipe 310 extends into the fermentation bin along the first direction and passes through multiple fermentation tanks 100. Multiple branch pipes 320 are spaced apart on the main pipe 310, and multiple branch pipes 320 are oppositely arranged in the second direction. There are multiple blower devices 200. The blower devices 200 are arranged on one side of the fermentation bin, and multiple blower devices 200 are arranged side by side in the second direction. There are multiple corresponding modular aeration pipe networks. Each modular aeration pipe network includes a main pipe 310 and multiple branch pipes 320. One end of the main pipe 310 is communicated with the blower device 200. The other end of the main pipe 310 extends into the fermentation bin along the first direction and passes through multiple fermentation tanks 100. The fermentation areas 110, blower devices 200, and modular aeration pipe networks correspond one by one. By performing stepped aeration on each fermentation area 110 in the second direction through multiple blower devices 200 and modular aeration pipe networks, heat dissipation can be carried out separately according to the cloth feeding time of each small-sized compost pile, saving energy consumption while ensuring the heat dissipation effect. Multiple branch pipes 320 are spaced apart on the main pipe 310, and multiple branch pipes 320 are oppositely arranged in the second direction. The branch pipes 320 are arranged towards the second direction, which can ensure the heat dissipation effect of the modular aeration pipe network on the fermentation area 110 and achieve sufficient heat dissipation.

[0053] According to some embodiments of the present application, the fermentation bin is provided with a groove, and the modular aeration pipe network is arranged in the groove. The modular aeration pipe network includes a main pipe 310 and multiple branch pipes 320. One end of the main pipe 310 is communicated with the blower device 200. The other end of the main pipe 310 extends into the fermentation bin along the first direction and passes through multiple fermentation tanks 100. The fermentation bin is provided with a groove adapted to the main pipe 310 and the branch pipes 320, and the groove accommodates the main pipe 310 and the branch pipes 320 of the modular aeration pipe network to facilitate the layout of the modular aeration pipe network.

[0054] According to some embodiments of the present application, the air-blowing device includes a blower and a blower control module. The blower control module is provided with a temperature sensor, and the temperature sensor is arranged in the fermentation bin. The air-blowing device 200 includes a blower and a blower control module. The blower control module is provided with a temperature sensor, and the temperature sensor is arranged in the fermentation bin. After the compost is distributed in the fermentation area 110, the temperature sensor is arranged in the middle of the compost heap. The depth of the temperature sensor in the compost heap is greater than 1 m. The temperature sensor is electrically connected to the blower control module. When the temperature sensor senses that the temperature of the compost heap reaches 65 °C or above, the temperature sensor sends a signal to the blower control module, and the blower control module controls the ventilation rate of the blower to be 0.1 - 0.2 m3 / (min·m3). When the temperature sensor senses that the temperature of the compost heap drops to 60 °C or below, the temperature sensor sends a signal to the blower control module, and the blower control module controls the ventilation rate of the blower to be 0.05 - 0.1 m3 / (min·m3). When the temperature sensor senses that the temperature of the compost heap drops to 45 °C or below, the temperature sensor sends a signal to the blower control module, and the blower control module controls the blower to stop ventilation. In some embodiments, the blower is set as a centrifugal fan. In some other embodiments, the blower can also be set as a Roots blower or an air pump, which can also achieve ventilation and heat dissipation of the fermentation area 110.

[0055] The following refers to Figure 2 Describe a composting system formed after the upgrade and transformation of a tank (bin) type composting system according to an embodiment of the present application.

A composting system includes a fermentation bin, an air-blowing device 200, and a modular aeration pipe network. The fermentation bin includes a plurality of fermentation tanks 100. The plurality of fermentation tanks 100 are arranged side by side in the first direction. Each fermentation tank 100 forms a plurality of fermentation areas 110 in the second direction. The arrangement of the plurality of fermentation areas 110 can realize the miniaturized distribution of the compost heap, so that the compost heaps in different fermentation areas 110 are in different fermentation times, and the heat generated by the decomposition of the compost heap is utilized to solve the problem of difficult heat generation. It can be understood that by arranging the fermentation areas 110 in the second direction and distributing the compost in the fermentation areas 110 in sequence, the compost heap that is distributed first will ferment and generate heat first, and the compost heap that is distributed later can utilize the heat energy generated by the decomposition of the previous compost heap, shortening the composting cycle, and at the same time avoiding the problem of difficult temperature rise of the compost heap and reducing the management difficulty of the composting process.

[0057] According to some embodiments of the present application, a plurality of aeration holes are provided on the branch pipe 320, and the plurality of aeration holes are evenly distributed on the branch pipe 320.

The fermentation tanks 100 form a plurality of fermentation zones 110 in the second direction. The setting of the plurality of fermentation zones 110 can realize the miniaturized feeding of the stack. The stacks in different fermentation zones 110 are in different fermentation times.
