Abstract
The invention belongs to the technical field of waste treatment, and relates to a treatment method for high-temperature high-humidity impact gas generated through hydrothermal degradation of waste. Malodorous gas sprayed out from a hydrothermal degradation tank is effectively treated through gas collecting and buffering, flow stabilizing under reduced pressure, temperature lowering, dewatering and drying and deodorizing. A gas collecting and buffering device can control sprayed gas flow and gas pressure impact, solve the problem of impact damage of the sprayed gas to equipment and control the gas flow to enable a treatment device to perform stabilized treatment. According to the treatment method, temperature lowering, dewatering and drying can be performed on the high-temperature high-humidity gas, so that the gas can enter a deodorizing system in a dry and low-temperature state; odor is treated by adopting treatment modes such as incineration, biochemistry and physical chemistry, and the purposes of malodorous gas removal and standard emission are achieved.
