Problems solved by technology

[0005] Therefore, it is of great significance to establish a system that can simultaneously test various aerosol characteristics of aerosol nozzles (such as droplet size, droplet size distribution, droplet velocity, water flow density, etc.) to study the aerosol characteristics of nozzles. However, the current nozzle testing device has very limited testing capabilities, such as the hybrid nozzle testing device disclosed in the patent CN1743830, which can only test the overall water flow rate of the nozzle under different air pressure and water pressure, but cannot test the variation law of water flow density in different spray areas , and the height of the nozzle cannot be adjusted. This test device has great limitations, and it is difficult to achieve a good test effect on the aerosol characteristics of the nozzle.

Embodiment Construction

[0046] The invention provides a test device for aerosol characteristics of nozzles, such as figure 1 As shown, the device includes a test device box 1, a nozzle 3, a test platform system, an air system 7, a water system 8, and a laser imaging system.

[0047] see figure 1 , the test device box 1 is a cuboid structure, which has a top surface, a bottom surface and four sides, and a light-transmitting observation window 2 is provided on the side, and the nozzle 3 is connected to the gas system 7 and the water system 8, thereby forming the test required. The spray nozzle 3 is installed under the top surface of the box and above the test platform 5 through a universal bracket (not shown), and the spray angle of the nozzle 3 relative to the test platform 5 can be adjusted through the universal bracket, and can be adjusted according to The tests required mounting different types of nozzles on a gimbal.

[0048] see figure 1 , The test platform system includes a vertically liftabl...

Abstract

The invention relates to a device for testing nozzle characteristics. The device comprises a testing device box, a nozzle, a testing platform system, a gas channel system, a water channel system and a laser imaging system. The device is used for testing aerial fog characteristics such as the drop grain diameters, the drop speed, the flow density at the different positions and drop grain diameter distribution of the different nozzles at different spraying heights at different air pressures and different water pressures. The device is high in testing accuracy, wide in adjusting scope, stable in operation and capable of testing the aerial fog characteristics of single-phase liquid flow and gas liquid two-phase flow.

Description

[0001] technical field [0002] The invention relates to the technical field of measuring aerosol characteristics, in particular to a test device for aerosol characteristics of a nozzle. Background technique [0003] None of the existing nozzle aerosol characteristic test devices can adjust the spray height of the nozzle, but because the characteristic parameters of the aerosol sprayed by the nozzle (such as particle size, droplet velocity, water flow density, etc.) change accordingly with the distance from the nozzle Whether the measurement of the characteristic parameters of the nozzle aerosol at different heights can be realized is an important technical problem to be solved by the present invention. [0004] Air mist nozzles are widely used in various fields of industry. In the secondary cooling of metallurgical continuous casting, the billets are cooled by the air mist jets generated by the nozzles. Therefore, the arrangement structure of the nozzles, the spray distance...
