AI Technical Summary

Technical Problem

Existing technologies lack early warning capabilities for microbial activity in industrial fluids, resulting in the inability to prevent microbial spoilage in a timely manner, causing economic losses and health threats. Furthermore, existing control methods suffer from problems such as long detection cycles, delays, and waste of chemical reagents.

Method used

An online control device based on an odor sensor is used to monitor the concentration of hydrogen sulfide in the fluid environment in real time through a high-sensitivity hydrogen sulfide sensor, so as to accurately capture SRB metabolic activity and trigger programmed sterilization or fluid parameter adjustment to form a closed-loop control system.

Benefits of technology

It enables real-time sensing and proactive prevention of industrial fluids, reducing the risk of corrosion, minimizing chemical waste, and protecting the safety of operators and the environment.

Abstract

This invention provides an online control device for industrial fluid microorganisms, characterized by comprising a bactericide dispensing unit and a gas detection unit. The bactericide dispensing unit dispenses a bactericide into a fluid tank. The gas detection unit comprises a gas detection chamber, a gas detection device, and a gas collection device. One end of the gas collection device is positioned in the air layer of the fluid tank, and the other end is connected to the gas detection chamber, inputting the gas from the fluid tank into the gas detection chamber. The gas detection device is installed in the gas detection chamber to detect the input gas. This invention features high detection sensitivity, as the sensor does not physically contact the working fluid, avoiding the drawbacks of contact sensors being susceptible to media contamination or corrosion. It also boasts high sensitivity, a compact structure, and a small size, making it more convenient to operate. It is suitable for intelligent liquid storage management scenarios in fields such as machining, pharmaceuticals, environmental protection, and energy.
