Air dryer for compound air chamber, drying method and smoke tester including air dryer

Abstract

The invention discloses an air dryer for a compound air chamber, a drying method and a smoke tester including the air dryer. The air dryer for the compound air chamber comprises a plurality of airtight air chambers formed by a plurality of circular cylinders, wherein the airtight air chambers are communicated with each other through an air chamber connecting pipeline so as to form a serial air chamber; a separating sleeve of a whirlwind guide slot is arranged at the upper end in each of the airtight air chambers; the first airtight air chamber is equipped with a whirlwind air nozzle and a condensate reflecting cover so as to form a whirlwind reflecting condensate dewatering air chamber; a second airtight air chamber is filled with a drying agent, so as to form a dewatering absorbing air chamber; a fine filtering air chamber is formed by the third airtight air chamber. According to the air dryer, a compound multi-stage cyclone separation technique and a grading drying absorption technique are adopted for realizing the effective separation of water in air and the fine filtering of impurities, and the air drying effect and the cleanliness of discharged air are improved.

Description

technical field [0001] The invention belongs to the technical field of smoke sampling equipment, and in particular relates to a composite air chamber gas dryer, a drying method and a smoke tester containing the same. Background technique [0002] When monitoring smoke and dust emissions, the sample gas collected by the smoke tester is often mixed with moisture. If the sample gas with moisture is not effectively removed before entering the smoke tester, it will enter the smoke test through the sampling pipe. In the instrument, it will not only cause damage to the equipment, but more importantly, it will affect the accuracy of the test results. Therefore, in order to solve the above problems, during on-site monitoring, the sampling system is equipped with a gas dryer, which will first dry the collected sample gas, and then enter the smoke tester for monitoring to improve the accuracy of the measurement results , while reducing damage to the instrument. [0003] Existing gas ...
