Embodiment 1

[0024] A crushing process of biomass fuel, the crushing process includes pretreatment, pre-crushing, secondary treatment, and then crushing, the specific steps are as follows:

[0025] 1) Pretreatment: Select the collected soft corn stalks and cut the stalks into 7-8cm straw sections, then place the straw sections in a clear water soaking tank, and ultrasonically soak them at a power of 700w and a frequency of 55Hz 25 minutes, the mechanical action of ultrasound is beneficial to the absorption of the soaking liquid by the straw, and at the same time, the cavitation of the ultrasound will physically destroy the lignin and cellulose of the straw, improve the subsequent crushing efficiency, reduce the bulkiness of the swollen straw, and remove it for soaking The finished stalks are placed on the hot press bed, the temperature of the rolling rollers is set to 110°C, the pressure is set to 15Mpa, and the speed is set to 4m / min. The soaked straw section is hot rolled for 3 times. Pr...

Embodiment 2

[0030] This embodiment is the same as Embodiment 1, except that the power of ultrasonic soaking in this embodiment is 500w, the frequency is 60Hz, the temperature of the rolling roller of hot rolling is 100°C, the pressure is 10Mpa, and the speed is 3m / min. The grinding pressure is 10Mpa.

Embodiment 3

[0032] This embodiment is the same as Embodiment 1, except that the power of ultrasonic soaking in this embodiment is 800w, the frequency is 40Hz, the temperature of the rolling roller of hot rolling is 120°C, the pressure is 20Mpa, and the speed is 5m / min. The grinding pressure is 15Mpa.

Abstract

The invention discloses a smashing process of a biomass fuel, and belongs to the field of processing of biomass fuels. In the preparation method, straws are treated in different physical and chemicalaspects by ultrasonic soaking and hot rolling pretreatment, grinding pre-crushing, half anerobic roasting secondary treatment and ultrafine secondary crushing, the compactness of the straws is improved favorably, filling operation of crushing is facilitated, meanwhile, the crushing efficiency is improved, finally, ultra-fine crushing is centrifugal knife type crushing, air flow is generated in a crushing process, particles in small fineness are separated from particles in large fineness under the centrifugal effect, meanwhile, the particles in large fineness can be secondarily crushed, doubleeffects of separating and crushing are achieved, the crushed particles are uniform, and in the whole crushing process, an effect of increasing heat of combustion and energy density of the prepared biomass fuel is achieved.

Description

technical field [0001] The invention belongs to the technical field of biomass fuel processing, and in particular relates to a crushing process of biomass fuel. Background technique [0002] Biomass resources are extremely rich clean and renewable resources. They are favored by people for their important characteristics such as renewability, sustainability, diversity, environmental friendliness and affinity to humans. Biomass raw materials are being developed Crushing processing is required in the early stage of utilization, and crushing processing technology is the key and decisive factor for the conversion and utilization of biomass energy. After crushing biomass raw materials, the particles change from large to small, the surface area per unit mass of the material increases, and the reduction of particle size can increase the total energy consumption. The size of the surface area and the size of the bonding between particles during the compression process can improve the ...
