Novel aerosol fogging oil tank

Abstract

The invention provides a novel aerosol fogging oil tank. An adjusting valve is arranged at the right end of a clean air inlet nozzle to be connected with a compressed air source, so that the pressureand the flow of air flowing through the clean air inlet nozzle can be adjusted through the adjusting valve, and high-concentration and low-concentration continuous adjustment can be carried out on required oil mist before a high-efficiency filter is detected; the air inlet pressure and flow of the air inlet are controlled, so that the oil mist in the box body flows smoothly; by the arrangement ofa filtering baffle plate, the oil mist is filtered before passing through an oil mist outlet nozzle, oil mist particles with the particle size of about 0.3 microns uniformly pass through the baffle plate and then are sprayed out from the oil mist outlet nozzle, and oil mist blocked by the filtering baffle plate is condensed and then falls back into the box body to be repeatedly used; by arrangingthe filtering baffle plate, oil mist with different particle sizes can keep good consistency, adverse effects on the whole detection system are avoided, the oil mist backflow phenomenon is prevented,the fogging effect is stable, the oil mist concentration is convenient to adjust, and the accuracy of a photometer leak detection method can be greatly improved.

Description

technical field [0001] The invention relates to the field of aerosol fogging equipment, in particular to a novel aerosol fogging oil tank. Background technique [0002] At present, the leakage rate detection of high-efficiency filters or ultra-high-efficiency filters is generally divided into two types: particle counter method and photometer and aerosol generator detection method. [0003] Since the counter method needs to be used in combination with a diluter, and the detection technology is immature, it is difficult to popularize. In terms of the scope of use, the photometer method has a wider range of use. [0004] The aerosol generator is an indispensable device in the photometer leak detection system. It is mainly used to send oil mist upstream of the high-efficiency filter to test the filter leakage rate. The aerosol fogging oil tank is the core component of the aerosol generator. , the existing aerosol fogging oil tank at least has the defects of unstable fogging eff...

Problems solved by technology

[0003] Because the counter method needs to be used in combination with the diluter, and the detection technology is immature, it is difficult to popularize. In terms of the scope of use, the photometer method has a wider range of use

[0004] The aerosol generator is an indispensable device in the photometer leak detection system. It is mainly used to send oil mist upstream of the high-efficiency filter to test the filter leakage rate. The aerosol fogging oil tank is the core component of the aerosol generator. , the existing aerosol fogging oil tank has at least the defects of unstable fogging effect and difficult adjustment of oil mist concentration, which seriously affects the performance of the aerosol generator and reduces the accuracy of the photometer leak detection method
