Incineration treatment and heat energy recovery method and system for pyroligneous liquor containing organic acid

The invention provides a method and a system for incineration treatment and heat energy recovery of organic acid-containing wood vinegar. The method comprises the following steps that (1) the vertical incinerator is started for incineration; (2) the combustion temperature range of the vertical incinerator is kept to be 700-1000 DEG C; 3) introducing the pyroligneous liquor containing organic acid generated in the biomass gasification system into a heat exchanger arranged on a smoke tube of the vertical incinerator; flue gas generated in the combustion process of the vertical incinerator can exchange heat with wood vinegar in the heat exchanger when passing through the smoke pipe, so that the wood vinegar in the heat exchanger forms high-temperature steam. And (4) the high-temperature steam is guided into a vertical incinerator to be incinerated, so that the organic acid contained in the high-temperature steam is completely incinerated, and harmless treatment of the wood vinegar containing the organic acid is
