Heating stove pollutant discharge and thermal efficiency evaluation test system and method for detecting pollutant discharge factors and thermal efficiency

Abstract

The invention provides a heating stove pollutant discharge and thermal efficiency evaluation test system, and belongs to the technical field of detection devices. The heating stove pollutant discharge and thermal efficiency evaluation test system comprises a fixed source combustion system and a test sampling system, the fixed source combustion system comprises a leakage test box body and a heating stove body arranged in the leakage test box body, and a metering device is arranged on the heating stove body; the test sampling system comprises a gas-collecting hood, a dilution pipeline with a built-in flowmeter, a fan and a chimney which are communicated in sequence, the gas-collecting hood is arranged above the chimney of the heating stove body, at least one sampling port is formed in the dilution pipeline, and the sampling port is provided with a sampling pipe connected to a tester. The heating stove pollutant discharge and thermal efficiency evaluation test system provided by the invention can simulate the dilution effect when the flue gas enters the actual atmosphere in the actual use process of a user, and helps to research the generation and diffusion mechanism of a pollution source in the atmospheric environment.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a pollutant emission and thermal efficiency evaluation testing system for heating stoves and a method for detecting pollutant emission factors and thermal efficiency using the testing system. Background technique [0002] At present, nearly 60% of households in rural China still use biomass and coal as the main fuel for daily life. Due to the influence and constraints of living habits and economic conditions, it is still difficult to completely ban low-efficiency stoves and low-quality fuels in rural areas. . According to the data obtained from the analysis of the sources of air pollutants, rural heating pollution has a very significant contribution to the formation and dispersion of regional haze, and it will also cause serious indoor air pollution in the family. In recent years, as various environmental protection organizations, women and children's associations, and...

Problems solved by technology

The traditional direct sampling method is limited by the concentration range of the measuring instrument, and it is generally impossible to directly test the ignition stage. According to the real-time online measurement data of researchers, the ignition stage is the stage with the highest pollutant emission concentration, so it cannot be ignored
