AI Technical Summary

Technical Problem

In the existing biomass pyrolysis carbonization test, the sampling device cannot meet the oxygen-free cooling requirements of the carbon layer, and can only sample a single carbon layer, which limits the comprehensive analysis of the carbon layer.

Method used

A cooling layered sampling device including a carbonization furnace, a cooling cylinder and a separation assembly was designed. The cooling cylinder was driven to rotate at high speed by a servo motor, and the separation cutting knife was used to push the separation cutter to perform layered cutting sampling of the carbonized substances, and the thermally-solved rack was placed on the and maintain a closed environment during cooling to avoid contact with oxygen.

Benefits of technology

It realizes efficient cooling and layered cutting sampling of carbon compounds, ensures the integrity and anaerobic conditions of the carbon layer, facilitates detection and analysis of different carbon layers, and avoids the adverse effects of external gases on the pyrolysis and cooling process.

Abstract

The present invention relates to the field of pyrolysis and carbonization, and in particular to a cooling and layered sampling device for biomass pyrolysis and carbonization experiments, comprising a stand, a carbonization furnace fixedly arranged at the center of the upper end of the stand, an upper end cover fixedly arranged at the top of the carbonization furnace, a push cylinder fixedly arranged on the upper end cover, a fixed sleeve fixedly arranged at the center of the bottom of the stand, a cooling cylinder rotatably installed on the outer side of the fixed sleeve, a through hole penetrating the stand to connect the carbonization furnace with the cooling cylinder, a placement frame for placing carbonized materials is arranged between the carbonization furnace and the inner cavity of the cooling cylinder, and the output end of the push cylinder passes through the upper end cover and is fixedly connected to the placement frame. In the present invention, the cooling cylinder rotates at a high speed, which can greatly increase the air flow speed on the surface of the heat dissipation fins, thereby effectively and quickly cooling the cooling cylinder, and at the same time, the separation cutters at different heights will simultaneously perform rotational cutting and separation on the carbonized materials, thereby realizing layered cutting sampling of the carbonized materials.
