Abstract

The invention discloses an evaluation device for coal-fired flue gas pollutant sorbent, which includes a simulation flue gas steel bottle carrying pollutant, a gas steel bottle carrying mercury, a mercury vapor generator, mass flowmeters A and B, a gas mixing tank, a two-way valve, a mercury state converting device, a mercury analyzer, a computer, a tail gas processing device and a fixed bed, wherein in the bed body of the fixed bed, glass beads with the particle size of 0.5 to 2mm or hard polyester material can be adopted as bed material, sorbent with the particle size of 0.5 to 1.5mm is dispersed in the bed material, and the mass ratio of the bed material to the sorbent in the fixed bed is 50-70:1. Through the adoption of the evaluation device for the coal-fired flue gas pollutant sorbent, provided by the invention, related pollutant entering the fixed bed such as SO2, NOx and HgO can be absorbed by the sorbent in the fixed bed at a certain temperature, so as to control the pollutant; meanwhile, the adsorption effect of the sorbent can be evaluated conveniently and quickly.

Description

technical field [0001] The invention relates to a device for evaluating smoke pollutant adsorbents and its application in the evaluation of flue gas pollutant adsorbents for coal-fired power plant boilers. Background technique [0002] Despite the development of various new energy sources, coal still plays a dominant role in the energy structure in the world, especially in my country, where it has reached about two-thirds, and this pattern will not change for a long period of time in the future. will change. For a long time, coal-fired thermal power generation units have dominated my country's power industry, and most of my country's large-scale power stations are conventional coal-fired power stations. The emission situation of sulfur oxides, nitrogen oxides, soot and trace elements emitted by coal-fired power plants is becoming increasingly serious, which has a great impact on the environment and human health, and thus directly or indirectly brings huge Economic losses. ...
