Solid Hazardous Waste
Solid hazardous waste recycling and processing equipment refers to specialized machinery designed to treat, detoxify, and recycle solid hazardous waste (e.g., chemical sludge, waste batteries, chromium salt slag, medical waste). Its core goal is to minimize environmental risks from toxic, corrosive, or reactive waste while recovering reusable resources (such as metals, energy, or raw materials), aligning with the principles of "waste reduction, recycling, and harmless treatment."
Core Equipment Types
The equipment system covers multiple processing stages, with four typical categories:
- Crushing & Sorting Equipment: Includes hazardous waste crushers (with anti-corrosion linings) and intelligent sorting machines (using AI + sensors). It crushes bulky waste into uniform particles and separates recyclable components (e.g., metals in waste electronics) from hazardous residues.
- Thermal Treatment Equipment: Mainly consists of incinerators, pyrolysis furnaces, and roasting kilns. It uses high temperatures (800–1200°C) to decompose toxic organic waste (e.g., medical plastic waste) into harmless gases (after purification) or recover energy (e.g., heat for power generation).
- Chemical Stabilization Equipment: Such as neutralization reactors and solidification mixers. It adds chemical agents (e.g., lime, chelating agents) to neutralize acidic/alkaline waste or fix heavy metals (e.g., lead, mercury), preventing their leakage into soil or water.
- Resource Recovery Equipment: Includes metal extraction devices (e.g., leaching tanks for waste batteries) and organic solvent recovery systems. It extracts valuable materials (e.g., lithium, cobalt from waste lithium-ion batteries) or reclaims reusable solvents (e.g., ethanol from chemical waste), turning waste into resources.
Key Functional Characteristics
- Safety & Environmental Protection: Equipped with anti-leakage structures (e.g., corrosion-resistant tanks) and exhaust gas/dust purification systems (e.g., activated carbon adsorption + bag filters) to avoid secondary pollution.
- Versatility: Designed to handle diverse hazardous waste types—for example, multi-purpose crushers can process both rigid waste (e.g., waste catalysts) and flexible waste (e.g., contaminated textiles).
- Intelligence: Integrated with IoT monitoring systems to track parameters like temperature, pressure, and pollutant emissions in real time, ensuring stable and compliant operation.
Typical Application Scenarios
- Industrial Sectors: Treats waste from chemical plants (e.g., resin waste), smelters (e.g., heavy metal sludge), and electronic factories (e.g., waste circuit boards).
- Municipal & Medical Fields: Processes medical waste (e.g., used syringes via incineration) and municipal hazardous waste (e.g., waste paint buckets via crushing + solidification).
- Battery Recycling Industry: Recovers lithium, cobalt, and nickel from waste power batteries through crushing, sorting, and chemical leaching.
