Claim 6:
7. The in-situ vapor injection thermal desorption device according to claim 2, wherein a number of each of the heat-transfer-oil inlets, the heat-transfer-oil outlets, the hot-water inlets, and the hot-water outlets is two;
wherein each intermediate connector (2) has two first heat-transfer-oil through holes (202), two second heat-transfer-oil through holes (203), two first hot-water through holes (204), and two second hot-water through holes (205); the first high-pressure-gas through hole (201) is disposed at a middle portion of the intermediate connector (2); and the first heat-transfer-oil through holes (202), the second heat-transfer-oil through holes (203), the first hot-water through holes (204) and the second hot-water through holes (205) are uniformly distributed around the first high-pressure-gas through hole (201);
each water-vapor coupling injection activation chip (3) has two third heat-transfer-oil through holes (302), two fourth heat-transfer-oil through holes (303), two third hot-water through holes (304), and two fourth hot-water through holes (305); the second high-pressure-gas through hole (301) is disposed at a middle portion of the water-vapor coupling injection activation chip (3); and the third heat-transfer-oil through holes (302), the fourth heat-transfer-oil through holes (303), the third hot-water through holes (304), and the fourth hot-water through holes (305) are uniformly distributed around the second high-pressure-gas through hole (301); and four gas-liquid spraying holes (306) are disposed on the water-vapor coupling injection activation chip (3).
