Abstract

The invention relates to a novel portable gas normal position monitor of flue gas and pipeline gas. Due to special structure design, gas composition of the flue gas and the pipeline gas can be directly tested at the normal position onsite, gas measurement error of water-soluble gas such as sulfur dioxide and ammonia caused by flue gas water condensation in extraction of the flue gas and the pipeline gas through an extraction method is avoided, and the monitor resolves the measurement problem of water-soluble gas such as sulfur dioxide and ammonia in high-humidity flue gas and pipeline gas.

Description

technical field [0001] The invention relates to a gas monitoring device, in particular to a novel portable flue gas and pipeline gas in-situ monitor. Background technique [0002] The traditional portable flue gas and pipeline gas monitoring method is the extraction test method. The technician uses a gas tester to insert the gas sampling tube of the flue gas and the pipeline gas into the flue pipeline, and starts the gas sampling pump to extract the flue gas. Gas, the extracted gas goes through complex processes such as filtration, heating, condensation (or pipeline heat tracing), and enters the main unit of the gas tester, and the gas detection element in the main unit directly tests the gas composition. [0003] At present, the heating and condensation method is often used in the testing of flue gas and pipeline gas. The condensed water in the extracted gas absorbs gases that are easily soluble in water, such as sulfur dioxide, ammonia, etc., resulting in the loss of gas c...
