Description

Technical Field

[0001] The present invention relates to the technical field of animal husbandry waste treatment, and in particular to an animal husbandry waste treatment device and a use method thereof. Background Art

[0002] Livestock breeding waste refers to livestock and poultry manure, livestock and poultry house bedding, waste feed, scattered feathers and other wastes in breeding farms. Among them, the vast majority are livestock and poultry manure. At the same time, a large amount of clean water is used when cleaning livestock and poultry breeding sites. After flushing, a large amount of manure-water mixture with a high liquid-solid ratio is produced. Therefore, the main components of breeding waste are: protein, hemicellulose, cellulose, lignin and ash.

[0003] Free-range livestock farmers still account for a large proportion of my country's livestock industry, and these free-range farmers are usually not good at handling waste generated by livestock breeding. Some of them directly make compost in open spaces. However, the feces contain a large number of organic microbial colonies. In the process of decomposing organic matter, they will consume a large amount of oxygen in the water and emit a large amount of odor, affecting the quality of groundwater and the air environment. At the same time, the feces contain a lot of smelly water, which can easily attract mosquitoes and pose certain safety and hygiene risks.

[0004] Therefore, if the livestock and poultry waste is not treated properly, it will not only cause serious environmental pollution problems, but also cause waste of resources. In addition, due to the high moisture content of livestock and poultry manure (usually ≥80%), the traditional thermal treatment processes such as incineration, pyrolysis, and gasification inevitably require solid-liquid separation and drying pretreatment, which consumes a lot of energy and has low efficiency. Therefore, a livestock and poultry waste treatment device that can be promoted is needed.

[0005] Hydrothermal carbonization is a process in which appropriate proportions of raw materials and water react in a closed reactor at a relatively mild temperature and autogenous pressure for a certain period of time to produce a carbon-rich solid product (hydrothermal charcoal). Hydrothermal carbonization can convert biomass into biofuels and stable solid carbon materials, achieve high-value-added reuse of low-value waste biomass, and solve the carbon emission problem of waste biomass treatment. Summary of the invention

[0006] The purpose of the present invention is to provide a device capable of hydrothermal carbonization treatment of livestock and poultry waste, mainly livestock and poultry manure, to achieve high added value recycling of low-value waste biomass, and at the same time solve the serious environmental pollution problem caused by livestock and poultry waste.

[0094] A method for using a livestock breeding waste treatment device, the method comprising the following steps:

[0095] A: First, the solid-liquid mixture of animal husbandry waste is drained and fed into the second feed port 24, the first motor 23 is started to drive the auger 22 to break it up and enter the first cavity 11 through the feed port 13, the third motor 41 is started to drive the driving block 42 and the driving plate 43 to rotate, so that the driving plate 43 drives the fixed plate 44 in contact with it to rotate, and indirectly drives the entire filter assembly to rotate intermittently to prevent the feed position from being fixed and causing blockage.

After the feeding is completed, the second telescopic rod 82 is started to drive the horizontal plate 84 to move downward. When the horizontal plate 84 moves to below the feeding port 13, the shell 1 becomes a closed space. As the horizontal plate 84 moves downward, the pressure in the first cavity 11 increases, which can cause the residual water to flow downward into the second cavity through the filter cloth layer 351 and the activated carbon layer 352. Until the second telescopic rod 82 moves to the preset position, each of the weight sensors 91 measures and sends a signal to the controller to measure the weight of the solids.

When the liquid-to-solid ratio is greater than the preset value, the pump 62 on the liquid outlet pipe is started to pump the sewage in the second cavity 12 into the water storage tank 63 until the preset liquid-to-solid ratio is reached; when the liquid-to-solid ratio is less than the preset value, the second telescopic rod 82 is reset, and the pump 62 on the liquid inlet pipe is started again to replenish the water in the water storage tank 63. After replenishment, the second telescopic rod 82 is repeatedly operated to move downward until the preset liquid-to-solid ratio is reached;

[0097] The liquid-to-solid ratio is 4 to 1;

[0098] C: After the second telescopic rod 82 moves downward to form a closed space in the shell 1, each second motor 310 is started to drive the first connecting rod 36 to rotate forward 90 degrees, so that each arc plate 35 is changed from a flat state to a vertical state, so that the solid residue above the arc plate 35 falls into the second cavity 12, and the resistance wire 51 is started to heat up. At the same time, the second telescopic rod 82 is driven downward to increase the pressure in the shell 1, so that the temperature is raised to 260°C, and the hydrothermal carbonization reaction is stopped for 6 hours. After the reaction is completed, all sewage in the second cavity 12 is extracted, and the solid hydrothermal carbon produced by the reaction is heated and dried, and the second telescopic rod 82 is reset, and the first telescopic rod 71 is started to extend upward, driving one end of the support plate 72 to move upward until it contacts the limit plate 73, and the discharge port 14 is opened for collection;
