Cryogenic organic waste gas recovery device

The utility model discloses a cryogenic organic waste gas recovery device which comprises a cryogenic tank, a hot melting tank and a rotary plate capable of rotating, the cryogenic tank and the hot melting tank are arranged side by side, one side of the rotary plate is located inside the cryogenic tank, the other side of the rotary plate is located inside the hot melting tank, and the rotary plate is arranged in the cryogenic tank. And low-temperature nitrogen coil pipes are mounted on the two sides of the upper portion of the rotating plate correspondingly. According to the utility model, the cryogenic tank and the hot melting tank are arranged, so that the low-temperature solidification process and the high-temperature melting process of organic matters can be carried out in different tanks, the situation that the service life of the tank is shortened due to repeated alternation of high temperature and low temperature in the same tank is avoided, and the service life of the tank is prolonged; the rotating p
