The invention discloses a coal gas purification system adopting a rotational flow plate gas-liquid separator. The coal gas purification system comprises a cylinder body, a lower end guide pipe, the rotational flow plate, a rotational flow separation chamber and an exhaust port, the rotational flow separation chamber is installed in the center of the top of the cylinder body, and a rotational flowplate is arranged in the center of the bottom end of the rotational flow separation chamber; a lower end guide pipe is arranged at the end, away from the rotational flow separation chamber, of the rotational flow plate, a downcomer is fixed to the bottom end of the rotational flow separation chamber on one side of the lower end guide pipe, the exhaust port is formed in the center of the top end ofthe cylinder body, the bottom end of the exhaust port extends into the cylinder body and communicates with the top end of the rotational flow separation chamber, and a gas receiving port is formed inthe outer wall of one side of the cylinder body; and one end of the gas receiving port extends into the cylinder body, and an air injection pipe is installed at the end, away from the cylinder body,of thegas receiving port. According to the invention, the phenomenon of leakage during gas injection of the purification system is reduced, the convenience of the purification system during use is improved, and the integrity of the barrel during use of the purification system is ensured.

The invention discloses high-temperature printing and dyeing waste gas treatment equipment. The equipment comprises a multi-stage filtering device, a gas-gas heat exchange device, a rotational flow tower, a Venturi scrubbing tower and an active mud washing tower which are communicated in sequence; the Venturi scrubbing tower comprises a washing tower body, wherein the top of the Venturi scrubbing tower is provided with an opening, the side wall of the Venturi scrubbing tower is provided with an outlet, and the outlet is connected with an exhaust fan; the washing tower body is internally provided with cleaning liquid, and is provided with a Venturi tube, and an inlet of the Venturi tube is connected to the top opening and is used for introducing waste gas treated by the rotational flow tower; the pipework of the Venturi tube is connected with a conical oblique nozzle, and the tail end of the conical oblique nozzle is inserted under the liquid surface; the waste gas passes through the pipework of the Venturi tube to form a high-speed airflow, and tangentially enters the portion, under the liquid surface, in the tower body through the conical oblique nozzle to form a large number of microbubbles, and the microbubbles are in full contact with the cleaning liquid to remove soot and particulate matter in the waste gas. The high-temperature printing and dyeing waste gas treatment equipment can process the waste gas of the printing and dyeing process efficiently and stably at low cost.
