Description

Energy and Resource System of Mushroom Waste Package

The present invention relates to an energy and resource system, in particular to the use of dry anaerobic ferment technology to process mushroom waste packages and agricultural organic solid waste and produce biogas, biogas residue and biogas liquid, so as to use the biogas treatment system, Biogas power generation equipment, biogas residue composting system, biogas slurry treatment system and biogas slurry mixing system are used to convert biogas, biogas residue and biogas slurry into usable electricity, organic fertilizer and liquid fertilizer.

By the way, with the rapid development of agricultural technology, the types of crops produced by artificial cultivation technology are increasing. Whether it is fungus, Antrodia camphorata, shiitake mushrooms and even Cordyceps can be cultivated artificially in large quantities. As far as the most common edible mushrooms are concerned, the current methods of artificial cultivation are mostly using mushroom packs (commonly known as space packs) or basswood cultivation, and basswood cultivation must cut the entire log section and require transportation and handling. Keep the bark intact and not fall off, so that the bacteria can be inoculated at a suitable temperature, and then after the fruiting and harvesting is completed, the mushrooms are allowed to grow and grow the bacteria to cultivate the fruiting again. The fungus bag is to add the crushed sawdust to rice bran, corn flour... and other organic matter, then fill it into the bag, and after sterilization and cooling, inoculate the bacteria in the bag mouth to grow the inoculated mushrooms. As the cultivation of basswood requires cutting down complete sections, and complicated procedures such as drilling holes, inoculating bacteria, sealing wax, etc., for mushroom cultivation, the use of mushroom packs only requires the use of wood chips of the appropriate tree species, and the cost is low, and the yield is large. Therefore, it is currently the first choice for mushroom cultivation.

According to statistics, the annual output value of domestic mushrooms exceeds 1.5 million tons, and most of the mushrooms are cultivated with mushroom bags. However, the harvested mushroom bags cannot be reused, so the wood chips can only be taken out and disposed of by composting. It takes 3 to 6 months to dispose of by composting. In terms of the domestic mushroom product cultivation and harvesting speed, most of the discarded bacterial bags cannot be composted in time, so it is easy to cause environmental pollution problems due to random disposal.

In order to improve the above-mentioned shortcomings, the Chinese Announcement No. CN208732942U patent discloses "a recycling system for waste bacteria bags", which includes a bag breaking mechanism, a crushing mechanism, a drying box, and an organic fertilizer mixing tank to use broken bags. The double-cutter of the bag mechanism breaks the waste fungus bag, and the waste fungus bag after the broken bag is separated from the plastic by the piercing tooth of the conveyor, so that the separated waste falls into the waste collection hopper, and then borrows them in order. The pulverizing mechanism and the drying box pulverize and sterilize the waste at high temperature, and then use the organic fertilizer mixing tank to mix the waste with other additives for use as fertilizer.

In addition, the Chinese Patent Announcement No. CN206744533U discloses "a device for producing fermented forage using bacterial bag waste." The film wrapping mechanism and the circumferential wrapping mechanism wrap a film on the outer surface of the columnar fermented forage, thereby improving the processing efficiency of the bacterial bag waste.

In view of the fact that the mushroom bags after the mushroom cultivation and harvesting cannot be reused, the wood chips in the waste mushroom bags can only be processed by composting. Therefore, it is easy to cause environmental pollution problems due to poor disposal efficiency.

Therefore, the purpose of the present invention is to mix the mushroom waste bag with agricultural organic solid waste and decompose the organic matter by dry anaerobic fermentation technology to produce biogas, biogas residue and biogas liquid, which are used for power generation and composting respectively. Organic fertilizer and liquid fertilizer improve the efficiency of recycling mushroom waste packages.

In order to achieve the foregoing objective, the present invention provides a mushroom waste package energy and resource utilization system, comprising: a dry anaerobic fermented fermentation system, the dry anaerobic fermented fermentation system includes at least one fermented fermentation tank, located in the fermentation tank content There are 51~100 weight ratio of mushroom waste bags and 0~49 weight ratio of agricultural organic solid waste.

Based on the above, by mixing the mushroom waste bag with agricultural organic solid waste and decomposing the organic matter through anaerobic fermentation technology, biogas, biogas residue and biogas liquid are produced, and the biogas is processed by the biogas treatment system to generate electricity through biogas power generation equipment. , And the biogas residue is turned into organic fertilizer through the biogas residue composting system. After the biogas slurry is processed by the biogas slurry treatment system, part of it is sprinkled into the fermentation tank, and the other part is poured into the biogas slurry mixing system to make liquid fertilizer, which is then used to upgrade the mushrooms. The efficiency of waste package disposal also produces usable electric energy and organic fertilizer, so that the mushroom waste package can achieve the effect of energy and resource utilization.
