The utility model discloses a special oil washing cooker for coal gas production, which comprises a spraying chamber, a cooling chamber, a coal gas collection chamber and a coal gas outlet. A coal gas inlet and a phenol water inlet are arranged in the spraying chamber; the coal gas outlet and a phenol water discharge outlet are arranged in the coal gas collection chamber; the spraying chamber is arranged at the upper end of the cooling chamber; the coal gas collection chamber is arranged at the lower end of the cooling chamber; a plurality of cooling tube bundles are placed inside the cooling chamber; the cooling chamber is provided with a circulation water inlet and a circulation water outlet; the cooling tube bundles are communicated with the spraying chamber and the coal gas collection chamber; a washing hole is arranged on the wall of the cooling chamber; and high-pressure water washes the outer walls of the cooling tube bundles through the washing hole. By adopting the technical scheme, a method that the high-pressure water directly sprays, scrubs and washes the outer walls of the cooling tube bundles replaces an original method of washing the outer walls of the cooling tube bundles by chemical detergent, and the special oil washing cooker avoids problems of corrosion and pollution, and can ensure scrubbing quality.
