Ecological oil condensing tower and preparation system thereof

The invention discloses an ecological oil condensing tower and a preparation system thereof. The condensing tower is composed of a tower body and a tower bottom, wherein the lower end of the tower body is provided with an air inlet and is connected with a gas-solid separator, and the upper end of the tower body is provided with an air outlet and is connected with an oil-gas separator; a plurality of spray pipes which are provided with spray heads and are horizontally arranged are penetrated in the wall body of the tower body; a pipeline is connected between the spray pipes of the tower body and the tower bottom. The condensing tower in the preparation system is integrated by the tower body and the tower bottom, and an oil storage tank and pipeline parts are omitted, so that the system is simpler and more reasonable in structure; the condensing tower does not depend on external circulation because of having a circulation cooling function, so that the production efficiency of ecological oil is increased.
