TL;DR: In this article, the authors discuss different design approaches for process control of spray dryer operation and present static and dynamic methods for open-loop control of the spray drying process, which is one of the major convective drying technologies for removing liquid from a suspension or solution.
Abstract: This chapter discusses different design approaches for process control of spray dryer operation. It presents static methods for open-loop control of spray drying process. Spray drying is one of the major convective drying technologies for the removal of liquid from a suspension or solution. The solution or suspension is sprayed by one or several nozzles, arranged in an array, into the spray tower, usually from the top, but there are also designs whereby the spray is introduced from the bottom or from the sides of the tower. Due to the industrial importance, process modelling of spray dryer operation is an active field of research and development, having led to models of varying degrees of complexity. The chapter also presents the applications of open-loop control and open-loop optimization and discusses the feedback and optimal control. It then provides some examples of the use of artificial neural network (ANN) for open-loop control and optimisation of spray drying operation.

TL;DR: In this paper, a bag-type dust collector was used for removing large-particle-size dust impurities in the tail gas and a spray tower was used to remove small-mediumparticle size dust impurity and harmful gas components.
Abstract: The invention relates to a system for treating tail gas of an aluminum smelting furnace. The system comprises a bag-type dust collector used for removing large-particle-size dust impurities in the tail gas and a spray tower used for removing small-medium-particle-size dust impurities and harmful gas components in the tail gas, wherein the bag-type dust collector and the spray tower are arranged in sequence. An atomizer used for spraying spray liquid is arranged at the top of the spray tower, a tail gas distributor is arranged on the spray tower, and the tail gas flows in the spray tower in a spiral mode. The system for treating the tail gas of the aluminum smelting furnace can conduct effective treatment on the tail gas of the aluminum smelting furnace and avoid environment pollution caused by tail gas emission.
