Analog flue gas mixing device based on high temperature humidity generator

Abstract

The invention belongs to the field of a flue gas monitoring and testing device, and particularly relates to an analog flue gas mixing device based on a high temperature humidity generator. The analog flue gas mixing device based on the high temperature humidity generator comprises a gas tank (2), a standard-gas flow meter (7), a moisture flow meter (8), a foam generator (10), a constant temperature water tank (11), a dry gas flow meter (15), a T-junction (16), a mixed moisture flow meter (17), a small testing case (20), a medium testing case (21), a mixed moisture pipeline (23), a standard-gas heating pipeline (24), a mixing gas tank (25), and a dew-point instrument (18). When the analog flue gas mixing device simulates flue gas mixture, the analog flue gas mixing device based on the high temperature humidity generator utilizes a mixed flow method to solve the problem that how to simulate a high temperature and high humidity state of the flue gas at first, and thus can simulate high temperature moisture with 0% to 30% volume occurred at the temperature of up to 165 degrees, and then adds the standard-gas with the high temperature moisture to achieve a higher gas composition and humidity accuracy based on the traceably calibrating function of the precision mirror surface dew-point instrument, so that an instrument calibration and other experiments can be achieved without being on the scene of the flue, and therefore the labor intensity of the staff is reduced and great convenience is brought for experimenters.

Description

technical field [0001] The invention belongs to the field of flue gas monitoring test equipment, in particular to a simulated flue gas mixing device based on a high-temperature humidity generator. Background technique [0002] The flue gas in the flue is often a high-temperature, high-humidity sulfur-containing gas. Thermal power generation companies, oil refineries, some chemical plants, electric power research units, and environmental protection departments often have to simulate the flue gas in the flue for instrument calibration and other experiments. Electrical, electronic, instrumentation and other products, parts and materials are often subjected to high-temperature and high-humidity tests or constant tests to check whether the quality, reliability, storage, transportation and use of products, parts and materials in harsh environments meet the requirements, etc. . [0003] Similar products on the market are either inconsistent with the flue gas temperature, humidity...

Problems solved by technology

[0003] Similar products on the market are either inconsistent with the flue gas temperature, humidity and sulfur content in the flue, and cannot meet the flue gas requirements in the simulated flue; or the accuracy of the reference instrument does not meet the requirements; or it is used to correct the environmental changes of the humidity probe Larger, difficult to calibrate, etc.; because various parameters of standard humidity are greatly affected by the environment, how to maintain a relatively stable and continuous measurement environment, so that the prepared high-temperature simulated flue gas is closer to the actual situation, and realize Testing flue gas performance in the laboratory is a major problem in simulating flue gas mixing devices
