Abstract

The invention discloses a saturator for a wide-temperature nanoparticle counter. The saturator comprises a saturation chamber and a pretreatment pipeline, wherein the saturation chamber comprises a saturation chamber body, a temperature control unit and a working medium, the working medium is loaded at the bottom of the inner side of the saturation chamber body, the working medium is alcohol, ester, silicone oil or a mixture composed of at least two of the ester, the silicone oil and the alcohol, the temperature control unit comprises a heating component and a temperature control module used for adjusting the temperature of the heating component, a mounting groove is formed in the bottom of the outer side of the saturation chamber body, the heating component is arranged in the mounting groove, an air inlet channel is formed in the side wall of the saturation chamber body, the opening of the air inlet channel in the inner side wall of the saturation chamber body is higher than the liquid level of the working medium, an air outlet channel is formed in the top of the saturation chamber body, a particle filter and a flow measurement and control module are arranged on the pretreatment pipeline, and the output end of the pretreatment pipeline is communicated with the air inlet channel. The saturator provided by the invention can be suitable for a wide-temperature nanoparticle counter.

Description

technical field [0001] The invention relates to the field of wide-temperature counting of nanoparticles, in particular to a saturator for a wide-temperature nanoparticle counter. Background technique [0002] The measurement of fine particles plays a fundamental role in the study of air pollution, but there are many sources of air pollutants, and their temperature also varies from room temperature to high temperature. The saturator in the existing particle counter is no longer suitable for the measurement of the number of particles in the polluted gas with wide temperature distribution. Contents of the invention [0003] The purpose of the present invention is to provide a saturator for a wide temperature nanometer particle counter. [0004] To achieve the above object, the present invention provides the following scheme: [0005] A saturator for a wide-temperature nanoparticle counter, comprising: a saturation chamber and a pretreatment pipeline; [0006] The saturatio...
