Analysis and treatment instrument in sludge drying equipment

Most of the sludge used in industrial production or regional construction must be dried. The preventive maintenance and measurement identification of drying detection system is an indispensable part of sludge automatic drying equipment.

According to Emerson Process Management, the in situ oxygen detector produced by Rosemount analytical was installed in the dalowie sludge treatment plant near Glasgow City. In order to monitor and transmit the monitored data and the working data of the equipment, the digital PlanWeb process equipment management software is adopted. This is an integral part of their whole new technology strategy, "Scottish water"; its purpose is to recover sludge economically and efficiently and make full use of reclaimed water resources after sewage treatment. This is also in line with the relevant provisions and requirements of EU regulations to reduce the discharge of sludge into lake water and river water as much as possible.

There is an important safety regulation in the working process of sludge equipment: in order to prevent explosion hazard, the dust content in the working environment and air of the equipment shall not exceed a certain limit value. In order to meet the strict detection requirements, the advanced world class 3000 oxygen meter produced by Rosemount analytical is adopted. This high-precision detector is used to ensure the safety and normal operation of sludge equipment.

The daldwie sludge drying plant is responsible for the drying of all sludge in the Glasgow area. More than one million people live in the area, and the daldwie sludge treatment plant can produce about 65000 tons of combustible energy per year from the sludge. This granular, sludge based artificial fuel has a calorific value equivalent to lignite; it can be used by local thermal power plants to generate electricity. The world class 3000 oxygen meter is a series of products, which has a variety of adaptability. It can be selected according to the structure and power. The instrument has high self-protection ability, and can work in the environment with heavy dirt, dust and humidity. Some specifications and varieties also have certain moisture resistance, which can be used in the water containing sludge of drying equipment.

Most oxygen measuring instruments are used to detect the optimization of combustion gas. In this case, the range of oxygen detector used in this case is 0-21% (volume) O2, and it has three alarms. It can send out alarm signal in time according to the preset oxygen concentration level.

PlanWeb technology is a measurement monitoring and testing power data display technology. The data analyzer produced by Rosemount analytical can transmit data information between detectors through common hardware devices. The current detection and monitoring data can be evaluated by AMS suite. The intelligent instrument management can carry out preventive equipment and instrument maintenance in advance, and can measure and identify the instrument and equipment of the detection system.
