This invention provides a device and continuous preparation method for wet chicken manure dispersed granules. It employs a granulation mechanism combining wet core extrusion with dry powder gravity-free coating, rapidly forming a dry shell structure on the surface of the high-moisture wet core within a twin-shaft gravity-free mixer. Through closed-loop powder return control, the undersize fine powder is simultaneously used as coating material and granulation seed powder, significantly reducing the drying load and achieving material recycling. Multi-stage through-flow low-temperature drying with bed permeability as an online control index maintains a high porosity in the dispersed granule bed, enabling rapid dehydration at 40-70℃. Compared to traditional drum drying, energy consumption is reduced by 20%-30%, ammonia volatilization loss is reduced by more than 40%, and the finished granules are uniform, with a moisture content ≤30% and no agglomeration, meeting the requirements of NY / T 525-2021 standard. This achieves continuous, low-carbon, and high-quality granulation production of high-moisture wet chicken manure.

This invention discloses a sludge drying and carbonization treatment equipment and process. The equipment includes a storage and conveying system, an integrated drying and carbonization system, a drying carrier gas treatment system, a flue gas purification system, and several pipelines. This invention simplifies the process of conventional carbonization, which uses separate drying and carbonization equipment (drying machine and carbonization furnace), by integrating drying and carbonization into one device, thus saving space. Furthermore, it adopts a multi-segment spiral tube configuration with a vertical arrangement. The multi-segment vertical arrangement saves space, and the multi-segment spiral tube configuration solves the problem of large air leakage in conventional drum drying and rotary kiln carbonization, thereby addressing heat loss and pyrolysis efficiency issues. It reduces heat loss due to air leakage in the drying and carbonization section, maintains an anaerobic environment, and improves pyrolysis efficiency. Moreover, the multi-stage spiral splicing configuration allows for adjustments in the number of spiral segments based on the sludge quality, providing greater design flexibility.
