Abstract
The invention discloses a solid desulfurizing agent for coal-fired flue gas. The solid desulfurizing agent is composed of iron oxide and zirconium dioxide. Compared with a current iron oxide desulfurizing agent, the solid desulfurizing agent disclosed by the invention is high in desulfurizing efficiency, not high in requirement on sulfur coal, and good in adaption.
Description
Technical field
The present invention relates to a kind of coal-fired flue-gas solid desulfurating agent.
Background technology
Coal-fired flue-gas is the mixture of gas and flue dust, is the main cause polluting residential block air.The composition of flue gas is very complicated, and gas comprises SO
2, NO
2, H
2s, CO, CO
2deng pernicious gas, and ash content, coal grain, oil droplet and high-temperature split product etc.Therefore the pollution of flue gas to environment is the combined pollution of multiple poisonous substance.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of coal-fired flue-gas solid desulfurating agent.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of coal-fired flue-gas solid desulfurating agent, described solid desulfurating agent is made up of iron oxide and zirconium dioxide.
The mass ratio of described iron oxide and zirconium dioxide is 10:(0.1-0.5).
Compared with existing ferric oxide desulfurizer, desulfuration efficiency of the present invention is high, less demanding to sulphur coal, and adaptability is good.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
embodiment 1
Coal-fired flue-gas is passed into fixed bed reactors, the hybrid particles thing be made up of iron oxide and zirconium dioxide of fixed bed reactors desulfurizing agent used to be mass ratio be 10:0.1.Outlet H
2the concentration of S is 0.003ppm.
embodiment 2
Coal-fired flue-gas is passed into fixed bed reactors, the hybrid particles thing be made up of iron oxide and zirconium dioxide of fixed bed reactors desulfurizing agent used to be mass ratio be 10:0.5.Outlet H
