The invention discloses a differential total scattering suspended particle concentration monitoring device, and a use method and application thereof. The differential total scattering suspended particle concentration monitoring device comprises a gas path circulation system and a light path detection system; and the gas path circulation system further comprises a tail gas suction unit used for maintaining the constant flow of gas path fluid and a neutralization charger connected with the particle size classifier. The inlet section of the particle size classifier comprises a sheath gas inlet and a tail gas inlet connected with a neutralization charger; the outlet section of the particle size classifier comprises a to-be-detected gas outlet which is coaxially distributed with the sheath gas inlet; and the light path detection system is connected with the detection bin so as to realize detection of light intensity in the detection bin. The use method comprises the step of calculating the concentration of particl
