How to measure atomizing spray particle size? Chengdu Jingxin Powder
In recent years, China's spray industry has grown steadily, and the position of the nozzle nozzle industry has become increasingly important. At present, nozzle atomization technology has covered almost all industrial fields, such as transportation, agricultural production, and people's daily life. In addition to the combustion of various fuels (gases, liquids, and solid fuels), atomization technology in non-combustion industries such as Catalytic granulation, food processing, powder coating, spray products, pesticide spraying, etc. are also widely used.
The function of the nozzle is to atomize the liquid and form a liquid mist with a small diameter. In order to comprehensively evaluate the atomization performance of the nozzle, a number of index parameters are proposed, including: atomization fineness, atomization uniformity, and atomization cone angle. The droplet size after atomization reflects the fineness of atomized particles and is an important indicator for evaluating the quality of atomization. In general, the finer the particles of the droplet, the easier it is to heat, evaporate and burn.
The important indicators for evaluating the performance of atomizing nozzles are the size of the droplet diameter and the spectral distribution of the droplet diameter. The fog field formed by the nozzle spray is composed of particles of droplets of different sizes, and the accuracy of the droplet size test has a great relationship with the method of droplet sampling and the accuracy of the measuring instrument.
Jingxin JL-3000 spray particle size analyzer can achieve: rapid sampling and measurement, with good droplet size resolution in the entire measured range; does not interfere with the atomization process during the measurement process, convenient measurement; built-in camera automatically In the system, the entire test process automatically turns on / off the air source under the control of the computer, and automatically ejects the measured water mist, oil mist, smoke, etc .; it can be repeated continuously and automatically tested, and the results are analyzed in tens of seconds, repeatability and stability Sex is good. The data can give typical values ​​of particle size D10, D25, D50, D90, D97, average particle size and specific surface area, interval particle size distribution (ie differential distribution) data and graphics (histogram or curve), cumulative particle size distribution ( That is, integral distribution) data and curves. Computer automatic record storage, viewing and printing are convenient.
This instrument has extremely high measurement accuracy. Due to the non-contact measurement of fog droplets using laser technology, the measurement error is reduced to very low. When the droplet diameter is 1 micron, the error is not more than 3%; the entire measurement process is extremely rapid, The measurement of mist droplets in the air does not exceed a few seconds, and the measurement range can reach 0.5 microns to 2000 microns. The distance between the main machine and the auxiliary machine can be adjusted up to 10 meters, and the user can adjust it according to his needs.
The spray laser particle size tester is a new type of particle size detection device that has emerged in recent years. It has the characteristics of real-time detection and has a wide range of applications. With the development of nozzle testing technology, the application of spray laser particle size analyzer in spray experiments is also getting more and more attention.
