![]() Nozzle characteristic is mainly affected by the following physical characteristics: General information about nozzle technology Full cone nozzles are mainly used by Ravebo in scrubbers with a packed bed because of their good liquid distribution and distribution. Without these elements, the nozzle would give a hollow cone image. Both types have a swirl body which breaks the rotating flow current. Because of these properties, this type of nozzle is therefore widely used for cleaning applications.Īs with hollow cone nozzles, full cone nozzles are designed as axial and tangential nozzles. As a result, the impact on the surface to be sprayed is much greater. In contrast to hollow cone nozzles, full cone nozzles produce a rather coarse drop which have a greater kinetic energy compared to the hollow cone nozzles. This means that the whole full cone nozzle is the first choice when an even surface spraying or liquid distribution is requested. ![]() These nozzles also have a cone-shaped spray image where, however, here the cone is completely filled with drops. Because of their homogeneous spray pattern with the fine droplets, the hollow cone nozzles are mainly used by Ravebo in gas scrubbers and quenchers.įull cone nozzles are used for the most diverse applications. Eccentric hollow cone nozzles are much less susceptible to clogging than axial types due to their lateral entry and therefore the lack of a swirl body. When the liquid film is squeezed out of the sprayer through the nozzle opening, a cone-shaped spray image is created. A tangential incoming liquid flow brings it into rotation so that the cylindrical inside of the sprayer is provided with a liquid film which affects the size of the droplet. ![]() Tangential (or eccentric) hollow cone nozzles are much simpler in construction than the axial nozzles. Axial hollow cone nozzles create the finest droplets of all types. This rotating liquid flow is then sprayed into the environment through a nozzle opening, creating the shape of a hollow cone. The incoming liquid flow in axial nozzles is in line with the connection where the liquid in the nozzle is brought into rotation by a specific swirl body. There are two types of hollow cone nozzles axial and tangential entry. This feature is especially important in the following applications: The main advantage of fine droplets is that the surface of all accumulated droplets is huge in relation to the other types mentioned. Hollow cones produce finer droplets than any other types of hydraulic nozzles. This type of spray nozzle is quite popular because of a very important property namely: droplet size. This type of sprayer is therefore used for the high pressure cleaning systems. Because of this last property, flat jet nozzles are extremely suitable for surface cleaning. The spray pattern is a liquid film directly in front of the spray nozzle and will turn further away from the nozzle into many droplets. The liquid distribution is determined by the shape and size of the nozzle. The spray pattern of flat jet nozzles looks like a sharp line which is caused by internal flow characteristics. The types of nozzles that are regularly used are the following: This is because the spray pattern often determines the application and its characteristics. The selection and layout of the nozzles is done on the basis of the spray image. This overview will certainly not be complete, but is mainly intended to provide an explanation of the types described. The nozzles that will be reviewed here are models and embodiments and applications that function on the basis of one medium and only liquids. ![]() We will limit this here to the spray nozzles for industrial use and then in particular those types that find their application in gas scrubbers that are used for gas cleaning to prevent emission of (harmful) substances. It goes too far to cover all types, characteristics and their purposes in this article. There are many types of liquid nozzles for as many applications ranging from agricultural applications to all kinds of industrial applications. For questions or technical support, it is advisable to contact one of our engineers. The overview is not complete and is especially not intended to be able to make a choice for the right spray nozzle based on the information provided. To create some clarity in this, background information is described here. The principle is generally clear, but when it comes to the choice of the ultimate spray nozzle for the application, it is often not known that the end result is determined by details. A relatively large amount is unknown to many engineers with regard to the underlying technique and the applicability for each application behind the nozzles.
