Abstract
The invention provides a gas-liquid separating tank for a gas exhauster. When the adopted gas exhauster works, a gas inlet of the gas-liquid separating tank generates a suction force, the exhausted gas is sucked into the gas-liquid separating tank for separation from the gas inlet, and the separated liquid is discharged. Two chambers, i.e., an upper chamber and a lower chamber, are arranged in the gas-liquid separating tank; the upper end of the upper chamber is provided with a mesh mist eliminator for eliminating the moisture in the exhausted gas; and the side face at the lower end of the upper chamber is provided with a high-level liquid level switch. The bottom of the lower chamber of the gas-liquid separating tank is provided with a pneumatic discharge valve, and the side face of the lower chamber of the gas-liquid separating tank is provided with a liquid level control switch. The high-level liquid level switch is connected with the control circuit of the gas exhauster; when the water level of the gas-liquid separating tank reaches to the mounting position of the liquid level switch, the gas exhauster is controlled to stop working so as to protect the equipment.
