HIGH-TEMPERATURE HIGH-PRESSURE BIOMASS SYNGAS COOLING AND PURIFICATION PROCESS AND DEVICE

摘要

A high-temperature high-pressure biomass syngas cooling and purification process comprises: 1) subsection cooling; 2) collecting and eliminating empyreumatic oil; 3) washing and purification; and 4) wet-type electrostatic precipitation processing. Also provided is a high-temperature high-pressure biomass syngas cooling and purification device, mainly comprising a shell-and-tube heat recovery boiler (2), a dry-gas filter (3), a vertical smoke-tube heat recovery boiler (4), a venture washing tower (5), and a wet-type electrostatic precipitator (6). The device of the present invention is simple, safe and stable; has low power consumption and high efficiency, and achieves good economic benefits.
