Gas sampling device for rotary cement kiln analysis
The patent US12066361B2 describes a sophisticated sampling device designed for the analysis of gas samples from a rotary cement kiln. The device features two gas sampling probes, each capable of moving between a retracted position and a sampling position, controlled by a dedicated control unit. This control unit orchestrates the operation of the probes, allowing one probe to withdraw and analyze gas samples while the other remains retracted and purged. The process is cyclical, ensuring continuous sampling and analysis by alternating the roles of the probes, thereby enhancing efficiency and accuracy in gas sampling.
Additionally, the device incorporates a purge system to maintain the integrity of the gas sampling probes when they are not in use. This system utilizes a blowing mechanism to eject a jet of compressed air, effectively cleaning the probes and preventing contamination. The probes are designed for longitudinal movement and can be powered by either pneumatic or electric drives. Each probe is equipped with a sampling tube specifically for extracting gas samples from the kiln, ensuring that the device is well-equipped for the rigorous demands of gas analysis in cement production environments.
