Definitions

  • the method according to the invention uses the number of drying goods entering the drying device for the regulation.
  • the control signal required for this can be taken from the existing system directly at the inlet lock in ordinary systems.
  • the control of the volume flow of the thermal treatment device supplied exhaust air flow and the The thermal treatment device itself takes place via a predetermined dynamic model that takes into account the thermal behavior and the concentration of organic substances within the drying device.
  • the model creates a prediction of the future process behavior on the basis of the number of incoming drying goods and thus enables a predictive control concept, which avoids the inertial effects known from the prior art.
  • the operation of the thermal treatment device can be adapted to the load, whereby a significant saving of fossil fuels in the thermal treatment device compared to the prior art can be achieved. Compared to customary control methods, it is possible to save up to 30% on existing systems.
  • the demand for electrical energy for the generation of different volume flows can be reduced for a controlled according to the invention drying system of a similar magnitude.
  • an exhaust gas stream of the thermal treatment device for heating at least one fresh air flow in a fresh air supply device for supplying fresh air into the drying device is furthermore used, wherein the volume and the temperature of the fresh air flow supplied to the drying device are regulated by means of the predetermined model.
  • the at least one circulating air flow by controlling the at least one fresh air flow in the fresh air supply device, an additional heat input into the drying device can be achieved and a heat supply deficiency in the drying device can be detected by detecting the temperature of the at least one heated fresh air flow through the predetermined model and fixed immediately.
  • the temperatures of the two streams are preferably measured after heating and enter as a controlled variable in the model, so that the model recognize too low heat input through the two streams can.
  • drying device 1 further heat can optionally be introduced by means of electric or gas-stream-heated infrared radiators (not shown).
