Abstract

The invention discloses a smoke sampling dewatering device which comprises a shell, a primary dewatering module, a secondary dewatering module and a tertiary dewatering module. The primary dewatering module comprises a first water storage cavity; the secondary dewatering module comprises a finned radiator and a multi-staged radiating pipeline, and a first water storage cavity gas outlet nozzle is communicated with a radiating pipeline gas inlet; the tertiary dewatering module comprises a drying chamber and a second water storage cavity, the multi-staged radiating pipeline is connected with a second water storage gas inlet nozzle, and the drying chamber is communicated with a smoke outlet nozzle. By the arrangement, other saturated gas enters the radiating pipeline gas inlet via the first water storage cavity gas outlet nozzle after passing through the primary dewatering module, quick cooling and dewatering are performed in the secondary dewatering module, condensed water is then stored in the second water storage cavity, and the gas is dried and filtered in the drying chamber prior to entering a host; the smoke sampling dewatering device is simple and reasonable in structural design, use amount of a drying agent can be reduced by three fourths, gas dewatering effect can reach more than 92%, and detection precision is obviously improved.

Description

technical field [0001] The invention relates to the field of smoke sampling and dehydration, in particular to a smoke sampling and dehydration device. Background technique [0002] The gas for flue gas monitoring must be dry before entering the instrument to ensure the measurement accuracy, so as not to damage the host, and the gas sucked in by the suction pump should also be dry. The flue gas of the traditional dryer is directly sucked into the dryer by the suction pump, and after absorbing the moisture in the flue gas through silica gel or molecular sieve, it enters the analyzer through the flow meter. However, after the flue gas has undergone wet dedusting, wet desulfurization and denitrification, the moisture content in the flue gas is still relatively large, and the amount of drying required is relatively large, and the drying is not thorough, which affects the accuracy of the measurement data. Contents of the invention [0003] The technical problem to be solved by ...
