Organic solid waste forming and low-temperature pyrolysis biochar preparation integrated device

Abstract

The invention discloses an organic solid waste forming and low-temperature pyrolysis biochar preparation integrated device and belongs to the field of low-temperature pyrolysis extrusion forming. Specifically, a driving motor is connected with a speed reducer, a driving shaft extends out of the left end of the speed reducer and is connected with an equal-diameter rotating shaft through a coupler, the left end of the equal-diameter rotating shaft is connected with a variable-diameter rotating shaft, the equal-diameter rotating shaft and the variable-diameter rotating shaft are integrated, and different spiral blades are distributed on the surfaces of the equal-diameter rotating shaft and the variable-diameter rotating shaft correspondingly; a feeding port and a water vapor outlet are formed in the top of a metal barrel, and a pyrolysis product outlet is formed in the bottom; a temperature-adjustable heating element wraps the exterior of the metal barrel, and a heat preservation box body is arranged outside the temperature-adjustable heating element; and a flange is installed at the left end of the metal barrel. According to the device, high-calorific-value biochar is prepared through the processes of low-temperature pyrolysis, extrusion forming and the like, the heating temperature of the heating element can be adjusted according to different types of organic waste, the application scene is wide, and the device is not affected by the types of the organic waste. The prepared biochar fuel has the characteristics of high calorific value, good ignition performance and stable combustion.

Description

technical field [0001] The invention belongs to the field of low-temperature pyrolysis extrusion molding, and in particular relates to an integrated device for organic solid waste molding and low-temperature pyrolysis biochar preparation. Background technique [0002] Organic waste such as straw can be dried and extruded to effectively solve the problem of its low bulk density, which restricts its large-scale utilization; in addition, due to the loose structure of organic waste such as straw, the high volatile content is easy to precipitate, making its combustion The process is extremely unstable. After crushing, drying and extrusion molding, this problem has also been well solved. [0003] However, the common organic matter forming devices currently on the market directly compress and form organic waste, and there are many types of organic matter and complex components. In order to make them extruded, complex pretreatment is often required, which greatly improves the organi...

Problems solved by technology

[0003] However, the common organic matter forming devices currently on the market directly compress and form organic waste, and there are many types of organic matter and complex components. In order to make them extruded, complex pretreatment is often required, which greatly improves the organic waste. In addition, direct extrusion molding cannot realize the selective utilization of components in organic waste, which greatly reduces the utilization efficiency of organic waste, and also makes the final solid fuel unable to adapt to some low-pollution combustion scenarios
