Abstract

The invention discloses a pre-processing system for straws. The pre-processing system comprises a straw crusher, a straw fine crusher and a straw tempering machine which are connected through two belt conveyers, wherein an additive inlet pipe is arranged at a feeding hole of the straw fine crusher; the straw tempering machine comprises a machine seat, a shell, a top cover, a main shaft, a motor and a transmission device, wherein the main shaft is arranged in the shell through a bearing; a feeding hole is formed in the top cover; a support plate connected with the shell is arranged outside the main shaft; an annular sieve cylinder is arranged on the support plate; a blanking hole is formed in the support plate outside the annular sieve cylinder; a discharging hole is formed below the support plate, and a receiving plate is arranged below support plate; at least two pressure rolls are arranged on the main shaft in the annular sieve cylinder through upper and lower linkage plates; at least one pressure wheel is arranged on each pressure roll through the bearing; at least two layers of longitudinal sieve holes are formed in the annular sieve cylinder; and a plurality of sieve holes are formed in each layer. The invention further discloses a pre-processing method for the straws. The system and the method have the beneficial effects that the treatment efficiency is high, the bulk specific weight and energy density of a product are substantially increased, the use is convenient, and the resource utilization rate is increased; and the system and the method can be applied to thermal cracking gasification.

Description

technical field

[0001] The invention relates to a pretreatment system and method for preparing biomass particle fuel from straw. Background technique

[0002] Biomass resources similar to straw are widely used in the preparation of pellet fuels due to their abundant sources and environmental friendliness; at present, when using straw to prepare pellet fuel, it is often difficult to shape during granulation; The operability of granulation is poor, just like extruding cotton, not only the processing efficiency is low, but also the bulk specific gravity and energy density of the pellet fuel are small, which is not convenient to use, but also reduces the utilization rate of resources; More efficient use of biomass pellet fuels, thermal cracking and gasification is becoming more and more mainstream, but this must be based on a higher specific gravity and energy density, and the existing treatment methods are all Unable to achieve, so that the use of pellet fuel is limited. Con...
