Description

Technical Field

[0001] The invention relates to the technical field of biomass drying, in particular to a centrifugal disturbance type biomass waste drying processor. Background Art

[0002] Biomass waste refers to various organic wastes generated in the process of agricultural production, forestry, animal husbandry, food processing, urban life, etc., such as crop straw, livestock and poultry manure, and the organic part of urban domestic garbage. These wastes have the characteristics of wide sources, high organic content, and easy to rot and deteriorate. If not handled properly, they can easily become breeding grounds for pathogens and mosquitoes and flies, causing pollution to the environment; Through drying treatment, the moisture content of biomass waste can be reduced, its calorific value and combustion efficiency can be improved, thereby increasing its utilization value as biomass energy or biomass fuel.

[0003] Prior art 1 (Chinese patent with publication number: CN114152033B) A biomass drying device comprises: a tower body, a coil heater, a power plant cooling water circulation pipeline and a sunlight introduction system. The tower body has a drying chamber. The coil heater is located in the drying chamber, and the coil heater is connected to the water source heat pump. The power plant cooling water circulation pipeline is connected to the water source heat pump. The sunlight introduction system is arranged on the tower body, and the sunlight introduction system is used to introduce the light irradiated on the surface of the tower body into the drying chamber. The biomass drying equipment realizes the drying of biomass in the form of coupling the waste heat of the circulating cooling water of the biomass power plant and solar energy, making full use of the resources within the power plant area and improving the comprehensive utilization efficiency of energy.

[0004] There is also prior art 2 (Chinese patent with publication number: CN104296519A), a biomass fuel drying device, in which a plurality of vertically arranged heat sinks are arranged inside the tank body, each heat sink is provided with a cavity, and the two ends of the cavity are connected to a heat carrier inlet pipe and a heat carrier outlet pipe. The heat carrier can flow through the cavity of each heat sink via the heat carrier inlet pipe, and after heat exchange with the biomass fuel between the heat sinks, it flows out from the heat carrier outlet pipe. The drying device uses a high-temperature heat carrier to enter the heat sink in the tank body to heat and dry the biomass fuel. It has a large heat exchange area, sufficient heat exchange, and high thermal energy utilization. At the same time, the heat carrier can be selected from high-temperature oil, with a large temperature difference during heat exchange and high thermal efficiency. Moreover, the heating medium and the heated substance are separated by the heat sink, which can also avoid the occurrence of dust explosions and improve safety.
