Nozzles and engineered solutions for upstream processes

Nozzles and engineered solutions for upstream processes For cooling and sprinkling tanks and systems, it is extremely important to spray the entire object with water on all sides or to provide an even water film on the object. The narrowest cross section of the nozzles should be ≥ 6 mm (DIN 14495). Tongue-type nozzles and full cone nozzles are frequently used. Droplets can be carried along in the gas flow. Lechler mist eliminators remove droplets from the gas flow in order to prevent down-stream measuring devices from being affected. Special full cone nozzles are available for cleaning mist eliminators. If the waste gas is to undergo absorption, Lechler full cone, hollow cone, or cluster nozzles are used. It is of crucial importance here to create a large specific reaction surface. The efficiency of the process can be decisively enhanced by making the right nozzle selection and having an optimum nozzle arrangement. In gas cooling, a liquid is added via nozzles that, under some circumstances, evaporates completely and thereby absorbs the thermal energy of the gas. Complete evaporation requires very fine droplets which can be produced with hollow cone or twin-fluid nozzles. Centrifuges are used to separate materials. Full cone and flat fan nozzles are used for this purpose to spray water on and wash out the material that is to be removed.
