Straw-fiber directional dismantling equipment

The utility model discloses straw-fiber directional dismantling equipment. The straw-fiber directional dismantling equipment comprises a dismantling tank, an air compressor, a fiber expansion bin, a pressure removing and discharging valve, a charging valve, an overheating steam generator and a control system. The dismantling tank is connected with the air compressor, and the air compressor pressurizes straw in the dismantling tank; the overheating steam generator is connected with the dismantling tank and conveys 350 DEG C high-temperature steam to the interior of the dismantling tank; the charging valve is arranged in the position of a material inlet at the upper end of the dismantling tank; the pressure removing and discharging valve is arranged in the position of a material outlet at the lower end of the dismantling tank and can be started within 1ms; the fiber expansion bin is connected with the outlet of the pressure removing and discharging valve. Compared with the prior art, the straw-fiber directional dismantling equipment can ensure that all kinds of straw and bamboo are within a steam explosion pulse time range and can being used for effectively carrying out dismantling to form high-valued biomass fiber at the convenience of the straw-fiber directional dismantling equipment along the natural growing trend of pipe wall of straw fiber at minimum critical dismantling force.
