Description
Technical Field
The invention belongs to the technical field of environmental monitoring, and particularly relates to an air-soluble adhesive tape air device of an electric mobility classifier.
Background
For characterization of particulate matter concentration in an environment, particulate matter mass concentrations, such as PM, are often used 2.5 And PM 10 Or the total concentration of particulate matter. However, the influence of the particulate matters of different particle sizes on the environment or individual is different, so that it is necessary to measure the concentration of the particulate matters of different particle sizes. For sieving of particle size of submicron-sized particles, the larger the particle size of the particles, the smaller the corresponding electric mobility, usually based on the characteristics of the electric mobility of the particles, when the particles are charged 1; the smaller the particle size of the particulate matter is, the larger the electric mobility is; the method is placed in a certain electric field intensity environment, and particles with a certain specific electric mobility particle size can be screened out by adjusting the electric field intensity, and an instrument based on the method is called an electric mobility classifier.
The most commonly used structure of the electric mobility classifier is a cylindrical coaxial structure, and comprises an inner electrode and an outer electrode, wherein the inner electrode is applied with high voltage, the outer electrode is grounded, and a radial electric field is formed between the two electrodes; on a flow field, the electric mobility classifier normally works and needs two air flows of sheath gas and aerosol, wherein the sheath gas is clean and dry air flow, is close to an inner electrode and is in laminar flow distribution; the aerosol airflow is close to the external electrode and is positioned between the sheath airflow and the external electrode, and in general, the sheath airflow is larger than the aerosol flow, and the larger the flow ratio of the sheath airflow to the aerosol flow is, the better the monodispersity of the particles screened by the electric mobility classifier is. When the high voltage of the inner electrode is fixed, the particles with certain specific electric mobility can pass through the sheath gas flow of the inner layer from the peripheral aerosol flow to reach the aerosol outlet, and then are measured by a downstream detector. The characteristics of the electric mobility classifier can be characterized by a transmission equation, and the half width of the transmission equation represents the resolution of the screening particle size of the electric mobility classifier under the condition that the diffusion loss, the equal aerosol inlet flow rate and the equal aerosol outlet flow rate are not considered, and when the flow ratio of sheath gas to aerosol is 10:1, the resolution is 0.1; the height of the transfer equation is 1.0.
One of the key points of the electric mobility classifier is whether the aerosol can be well uniformly distributed between the sheath gas flow and the external electrode, and the gas distribution non-uniformity of the aerosol can directly lead to the asymmetry of a transmission equation of the electric mobility classifier or influence the height and half width of the transmission equation. The conventional air-soluble adhesive tape has the following air modes: firstly, an aerosol buffer zone is enlarged, such as a 3081 type electric mobility classifier manufactured by TSI corporation in America, a larger buffer zone is arranged in an aerosol inlet area, and a slit area is enlarged to achieve the purpose of uniform gas distribution; secondly, gas distribution is carried out in a mode of adding gas distribution holes, such as an electric mobility classifier produced by GRIMM company, and small holes are distributed on the circumference of an aerosol inlet area; thirdly, one path of aerosol is separated into multiple paths outside the electric mobility classifier by a mode of multiple aerosol air inlets, so that the complexity of a system is greatly improved; fourthly, the aerosol rotates in the electric mobility classifier through tangential airflow, and the method ensures that the airflow has larger tangential velocity and is easy to cause non-uniformity of the aerosol adhesive tape.
In summary, how to realize the gas distribution device to reduce the buffer volume of the aerosol inlet, reduce the loss of particulate matters at the inlet, and improve the screening and transmission efficiency of the electric mobility classifier has become a urgent issue to be solved.
