Potassium chloride aerosol generation method and potassium chloride aerosol generation device

Abstract

The invention provides a potassium chloride aerosol generation method and a potassium chloride aerosol generation device. The potassium chloride aerosol generation device comprises a gas storage cylinder, an atomizing chamber and potassium chloride solution. The gas storage cylinder is used for storing filtered and purified gas and connected with two pipelines. The first pipeline is connected to a nozzle arranged at the top of the atomizing chamber. The potassium chloride solution is connected to the nozzle through a solution pump. The second pipeline is provided with an air heater and is connected to a hot air outlet at the bottom of the atomizing chamber through a pipe. The gas storage cylinder is further connected with a third pipeline, and the third pipeline is connected with an air cooler and an air dryer, and is connected to the top of a condensing chamber through a pipe finally. The bottom of the atomizing chamber is connected to the top of the condensing chamber through a pipe, and an aerosol outlet is arranged at the bottom of the condensing chamber. With the potassium chloride aerosol generation device, moisture evaporation of liquid potassium chloride drops and crystallization of potassium chloride aerosol are realized respectively, the potassium chloride aerosol generation process can be controlled more accurately, and potassium chloride aerosol generated finally is guaranteed to be free of moisture.

Description

technical field [0001] The invention relates to the fields of air cleaning technology and air filtration, in particular to an aerosol generation method and a device thereof in an air filter detection system. Background technique [0002] With the popularization of automobiles, the importance of air filters to protect the performance of internal combustion engines and engine equipment has received more and more attention. Therefore, it is necessary to scientifically detect and evaluate the performance of air filters. European, Japanese, Chinese and early international standards have always used gravimetric efficiency to test the performance of air filters, but now the measurement efficiency of air filters has begun to become a new international standard. In the metering efficiency test system, the aerosol generator is a key component, because the aerosol particle size, concentration and stability generated by the aerosol generator will ultimately affect the results of the air...

Problems solved by technology

[0003]Currently available sodium chloride and potassium chloride aerosol generators use a single tall cylinder in which heated air is used to The disadvantages of this technology are: (1) the height of the cylinder is too high; (2) the humidity in the cylinder is too high to cause the final aerosol to contain moisture
