AI Technical Summary

Technical Problem

The existing technology is difficult to effectively deal with and utilize straw resources, resulting in environmental pollution and land occupation problems. At the same time, heavy metals in the soil are difficult to degrade, which poses health risks.

Method used

The intelligent straw resource environmentally friendly carbon production pretreatment and processing technology is adopted, including cleaning, chopping, drying, and carbonization. The straw is converted into biochar by carbonization, and the biochar is used as an adsorbent to remove heavy metals in the soil or water.

Benefits of technology

It solves the environmental pollution and land occupation problems caused by straw combustion, and at the same time significantly reduces the migration and biotoxicity of heavy metals in the soil, improves the soil environmental quality, and provides a clean and efficient adsorbent.

Abstract

The present invention discloses an intelligent straw resource environmentally friendly charcoal making pretreatment process, which belongs to the field of environmentally friendly charcoal making technology. An intelligent straw resource environmentally friendly charcoal making pretreatment process, raw material preparation: before straw carbonization, the straw raw material is cleaned, chopped and dried to ensure the quality and uniformity of the raw material; raw material feeding: the treated straw raw material is transported to the carbonization furnace, and the feeding is uniform to ensure that the exhaust passage inside the carbonization furnace is unobstructed, and to ensure that there is enough oxygen supply during the carbonization process. In order to solve the problem that heavy metals in the existing soil are difficult to degrade, mobile and toxic, and can enter the body of animals and plants through the food chain after long-term accumulation in the soil, posing health risks to humans, the straw resource treatment not only solves the environmental pollution caused by straw burning and the land occupation problem covered on the land, but also can be used as a clean and efficient adsorbent to remove heavy metals in soil or water.
