Organic recycling with a pipe-cross or tubular reactor |
摘要 |
The invention is directed to a process for enhancing the plant nutrient value of relatively low analysis organic waste material (e.g. sewage sludge) involves treating the waste material with an acid and base in a pipe-cross reactor or tubular to form a melt; spraying the melt onto a recycling bed of fines in a granulator and flashing off the water contained in the melt as steam; rolling the melt onto recycled fine particles in a granulator to form granulated particles; and drying these granulated particles to form an enhanced plant nutrient value composition (e.g. a fertilizer or soil conditioner having a greater NPK value than the original relatively low analysis organic waste material). The process further includes drawing off the fumes from the granulator, passing them through a dryer with the granulated particles, and subsequently oxidizing the fumes to eliminate volatile organic compounds and/or gaseous hydrocarbon pollutants be converting such into carbon dioxide and water vapor.
