High-temperature and high-humidity organic waste gas thermal incineration equipment and method

The high-temperature and high-humidity organic waste gas thermal incineration equipment comprises an outer shell, an inner shell is arranged in the outer shell, a heat preservation layer is arranged between the outer shell and the inner shell, and an inner part is installed in the inner shell; the invention further discloses a thermal incineration method for the high-temperature and high-humidity organic waste gas, and the thermal incineration method comprises the following steps that S1, the induced draft fan is started, and air enters the lower heat exchanger from the air inlet pipe under the action of the induced draft fan and is heated through the lower heat exchanger. Mixed gas of air and waste gas is heated to 650-800 DEG C through electricity or other fuel, organic matter and malodorous matter in the mixed gas are oxidized into water, carbon dioxide or other oxides through oxygen in the air to be purified, high-temperature gas firstly enters the upper heat exchanger from an annular gap between the comb
