Atomization performance detection system and method

Abstract

The invention relates to an atomization performance detection system and detection method. The atomization performance detection system comprises: a detection housing (10) having a hollow chamber; a liquid mist baffle (11) which is arranged in the hollow cavity and divides the hollow cavity into a mist spraying chamber (A) and a detection chamber (B), wherein the liquid mist baffle (11) is provided with a mist penetrating hole (11a) which penetrates through the liquid mist baffle (11) and is communicated with the mist spraying chamber (A) and the detection chamber (B); the atomizing nozzle (20) which extends into the spraying chamber (A) and is configured to spray liquid mist to the spraying chamber (A); and the optical fog meter (12) which is provided with a detection end positioned in the detection chamber (B), and is configured to perform atomization particle size detection on the liquid fog entering the detection chamber (B) through the fog penetration hole (11a). According to theembodiment of the invention, the atomization particle size test precision under the dense spraying working condition can be effectively improved.

Description

technical field [0001] The present disclosure relates to the technical field of detection, in particular to an atomization performance detection system and detection method. Background technique [0002] Spray technology is widely used in combustion equipment such as industrial furnaces, boilers, and thermal power plants, as well as non-combustion equipment such as spray drying, surface cleaning and coating, and agricultural irrigation, which can affect the combustion efficiency, combustion stability, temperature distribution, and pollution of combustion equipment. It has an important impact on the productivity, product quality and cost of non-combustion equipment. [0003] In some working conditions, a larger flow rate of liquid spray is required. For example, the oil output of some large-scale industrial fuel burners can reach more than 3000kg / h, and the liquid mist is relatively dense. For such large-scale equipment, the nozzle structure generally adopts the method of mu...

Problems solved by technology

[0004] In engineering applications, instruments based on the principle of reflection, refraction light interference or diffraction and scattering light are generally used for atomization particle size detection. Commonly used optical fog measurement instruments include laser Doppler velocimeters, Doppler laser particle analyzers, Malvern Particle analyzers, etc., have the advantages of fast test speed, high precision, wide range of test particle sizes, and no influence on the liquid mist field, but there is a problem of low detection accuracy for dense sprays

Other atomization detection equipment focuses on the construction of the test platform, and pays insufficient attention to the problem of low test accuracy caused by dense spray conditions and spray splashing.
