What Types of Spray Nozzles Can be Used in Paper Making?
Importance of Spray Nozzle in the Paper Making Process
For the paper industry, spray nozzle play an extremely important role in the papermaking process. Spray nozzles are mainly used for cleaning in the papermaking process. The quality of paper is determined by the effectiveness of cleaning. But the importance of nozzle is often overlooked by production site personnel. A small nozzle can often solve many problems. However, inappropriate choices may lead to paper diseases such as wrinkling, curling, and edge bleeding. Incorrect use of spray nozzles may also cause other issues:
Poor cleaning performance can affect the service life of the press felt, forming fabric, and rollers.
Poor spray coverage and overlap can affect paper quality.
Using inappropriate spray nozzles leads to more water and chemical waste.
Causing unnecessary downtime for maintenance and increasing operational costs.
Types and Application of Paper Machine Spray Nozzles
Trimming Nozzle
The trimming nozzle body can be made of brass or 316L stainless steel, and the inlay can be made of 316L stainless steel, hard alloy, ceramic, ruby or sapphire. The performance of the edge cutting water needle directly affects the quality of paper products and is one of the key links in the papermaking process. The precision and wear resistance of water needles have a significant impact on the quality of paper production and workshop efficiency.
High Pressure Spray Nozzle
The cleaning effect of the mesh is a key factor that cannot be ignored in the papermaking process. The occurrence of most paper diseases in the manufacturing process is closely related to the cleaning effect of the mesh. Choosing high-quality high pressurea spray nozzle products has a significant impact on both cleaning effectiveness and production efficiency. The commonly used pressure for cleaning the mesh is 25-30 bar, and for high-speed paper machines, it is generally used in conjunction with a swinging device.
Spray Nozzle Used for Cleaning Dryer Fabrics and Cutting Paper
The quality of dryer fabric cleaning is directly related to the surface quality of paper products. Due to the unique location of the dryer fabric, extremely high pressure is required for cleaning, which places extremely high demands on the performance of the spray nozzle. Generally, hard alloy or sapphire is used.
Fan Type Spray Nozzle
Fan type spray nozzle is generally suitable for low-pressure spraying and lubrication, with a pressure range of 3 to 5 bar. The correct selection of the model has a direct impact on water consumption and blockage. The correct selection of spray nozzles has a significant impact on water conservation, energy efficiency, and spraying effectiveness.
Spray Nozzle Starch and Chemical Spray
Chemical spraying occupies a large space in the production cost of papermaking. Reasonable selection of nozzles has a significant effect on improving production efficiency and reducing cost consumption.
Spray Nozzle for Paper Humidification
In the production process of tissue paper, the generation of a lot of dust can have adverse effects on production quality and human . Eliminatihealthng dust has a positive effect on both environmental protection and health. At present, spray dedusting is the most cost-effective way.
