Device for preparing biochar from wet crop straw and rotten vegetable leaves

Abstract

The invention discloses a device for preparing biochar from wet crop straws and rotten vegetable leaves, and belongs to the field of biochar preparation, the device comprises a drying chamber, a squeezing chamber is arranged at the upper part of one end of the drying chamber, a feeding chamber is arranged at the upper part of the squeezing chamber, a crushing chamber is arranged at the lower part of the other end of the drying chamber, and a high-temperature chamber is arranged at the lower part of the crushing chamber; a discharging pipe is arranged on one side of the bottom of the high-temperature chamber; a squeezing mechanism and a heating mechanism are arranged in the squeezing chamber; a conveying mechanism is arranged in the drying chamber, an air heater and a drying pipe are arranged on the upper side of the drying chamber, the drying pipe is connected with the interior of the drying chamber, and a water outlet pipe is arranged on the lower side of the drying chamber; according to the device, wet crop straw and rotten vegetable materials can be squeezed and dried, moisture in the materials can be fully removed, then the materials are crushed and then subjected to high-temperature decomposition treatment, and the materials are uniformly distributed in the high-temperature chamber, so that the materials are uniformly and fully heated, and the quality and the production efficiency of prepared biochar are improved.

Description

technical field [0001] The invention relates to the technical field of biochar preparation, in particular to a device for preparing biochar by utilizing wet crop straw and coriander. Background technique [0002] Biochar is a type of charcoal that acts as a soil conditioner to aid plant growth and can be used for agricultural purposes as well as for carbon capture and storage, as opposed to conventional charcoal that is generally used for fuel. The traditional preparation method of biochar is to burn wood, straw or crop waste in an oxygen-deficient environment to obtain biochar. [0003] After searching, Chinese Patent No. CN 206692596 U discloses a device for preparing biochar by using wet crop straw and coriander; it includes a casing, a feeding port arranged on the top of the casing, and a feeding port arranged inside the casing and communicating with the feeding port. a material drying chamber, a material pulverizing chamber arranged inside the shell and communicated wi...

AI Technical Summary

Problems solved by technology

[0004] The devices in the prior art still have the following disadvantages when using wet crop stalks and tail vegetables to prepare biochar: the moisture in the wet crop stalks is large, and the drying efficiency of the commonly used drying methods is low; at the same time, the materials are distributed in the carbonization chamber. Uneven, resulting in uneven carbonization of materials, increasing carbonization time, and the quality of the prepared biochar is poor, so the present invention proposes a device for preparing biochar by using wet crop straw and tail vegetables
