Device for measuring optical spectrum of flowing liquid

A device for measuring an optical spectrum of a flowing liquid, comprising:

• a flowing liquid mechanism, wherein the flowing liquid mechanism comprises:
• a valve body, wherein a cylindrical valve cavity is formed in the valve body, an outer wall of the valve body is further provided with a valve-cavity through opening communicated with the valve cavity, so that a liquid enters the valve cavity through the valve-cavity through opening to rotate, a gas/liquid port communicated with the valve cavity is formed in a center of an end face on one side of the valve body, the flowing liquid rotates along the valve cavity, and gas and/or liquid is discharged along the gas/liquid port;
• and
• a detection mechanism, wherein the detection mechanism comprises:
• a transmitting assembly wherein the transmitting assembly is located on one side of the valve body and configured to transmit detection light, and the detection light irradiates along an axial direction of the valve cavity without passing through a central area of the valve cavity, so that the detection light penetrates through the liquid flowing in the valve cavity;
• a receiving assembly, wherein the receiving assembly is configured to receive the detection light penetrating through the flowing liquid and generate a detection signal;
• and
• a processing module, wherein the processing module is configured to receive and process the detection signal.
