Tribolelectric and dynamic sensors in innovative monitoring systems for process integrated environmental control

Objective

Objectives
The technical, economic and social objectives of the project proposed are
* Development of cost-effective, low-maintenance monitors based on simpler technology than the existing ones,
* Verifying their reliability and suitability for end user,
* Reducing dust emissions and saving energy,
* Improving occupational conditions (e.g. workplace),
* To bring about ecological and economic benefits by integrating environmental protection with production.
State of progress
* First project meeting in February 1999
* Contacts are continued to Derix and LATE to know process and installation conditions.
* Start of laboratory tests at TÜV Rheinland.
* Planning of tests are running for PCME and Födisch-sensors.
* On site installation is planned in detail for Derix.
Background
In Europe there is an estimated number of more than 10.000 plants existing, especially in SMEs that are sources of dust emissions to the environment. To improve this situation the innovative way of production-integrated environmental control measures is considered as the best approach. This can only benefit the SMEs if concrete technical and financial advantages can be achieved at low costs.
Workprogramme
In the first step different triboelectric sensors are investigated in laboratory and wind-tunnel tests in order to determine
* principal performance characteristics
* effects of velocity range (5 - 25 m/s),
* variety of dust concentrations (0 - 50 mg/m³, 50 - 150 mg/m³ and 0 - 10 mg/m³),
* effects of different particle sizes and dust materials like quartz, micro-calcilin and plaster.
In the next step the instruments are installed at two plants and used under normal operating conditions. During the field tests the following work items are foreseen
* regular checks of the basic functions,
* periodic manual measurements on site using reference methods,
* calibration of the monitor,
* data collection to describe the monitor's characteristics,
* data evaluation for comparison purposes and determination of statistic parameters.
