A laboratory flue gas treatment evaluation research platform

Abstract

The invention relates to a laboratory flue gas treatment evaluation research platform, including a coal-fired boiler, a powder sprayer, a bag filter, an automatic online detection system for testing the dust removal efficiency of the bag filter, and a device that can evenly distribute and heat the dust Heating diffuser vessel, cooler and control system for controlling the duster. The present invention can study the dust removal efficiency of dust with different particle sizes and mixed substances, and can conduct high-temperature evaluation experiments and low-temperature section flue gas experiments at the same time, and can evaluate the influence of different temperatures, particle sizes, flow rates, pressures, etc. on the bag filter bag (dust removal) Efficiency, service life, etc.), can also evaluate the impact of different types of filter bags on the dust removal efficiency of the bag filter.

Description

technical field [0001] The invention relates to a laboratory flue gas treatment evaluation research platform. Background technique [0002] The existing flue gas treatment evaluation research platform usually does not design coal-fired boilers, but achieves the experimental purpose by mixing gas and powder, and usually can only do ordinary experiments at room temperature. Its fatal shortcomings are: 1. When doing experiments, only gas and powder can be prepared in advance. These dusts are at room temperature, without heating, high-temperature experiments cannot be carried out, and the effects of different temperatures and flow rates on bag filter bags cannot be studied. The impact (dust removal efficiency, service life, etc.), experimental research is limited. 2. In the process of experimental research, the degree of automatic control is relatively low, and it is not possible to conduct comparative experiments to evaluate its dust removal efficiency. 3. The dust mixed into...

(dust removal efficiency, service life, etc.), experimental research is limited

3. The dust mixed into the pipeline during the experimental research process is not uniform enough, and the error of the experimental research results will be relatively large
