75um。
Used as present invention further optimization, adsorption tower, desorption column adopt circulating fluid bed reactor in CCS systems, its
The reaction temperature of middle adsorption tower is 650 DEG C, and the temperature of desorption column is 900 DEG C, and adsorbent is given up using the cement plant after desulfurization
The carbide slag that temperature is dried more than gas.
In the joint production process of this programme, raw material use the calcium carbide waste slag of dry method acetylene technique acquisition, Jing Guo electricity
After magnetic is dried except iron and cement plant waste gas residual heat, CO in CCS systems is used as2The adsorbent of trapping, this measure solves calcium carbide slag muck
The occupancy of land resource of being rivals in a contest and the pollution problem to environment, while reducing the carbon emission amount in cement plant.In addition, dry carbide slag
Before sending into desorption column calcining, first it is dried via the remaining temperature of cement plant waste gas, on the one hand can traps the part CO in waste gas2, separately
On the one hand the remaining temperature of waste gas is used, further reduces the moisture in dry carbide slag, to obtain higher economic benefit.
The present invention, using the CO in discarded dry carbide slag trapping cement plant discharge waste gas2, on the one hand solve calcium carbide and give up
A pollution difficult problem for slag, at the same it is consistent with the low-carbon (LC) policy that country advocates, substantially reduce the carbon emission amount in cement plant.And inactivate
CaO be used for preparing cement, it is to avoid the waste of resource, can be with the stacking pollution problem of effectively solving carbide slag, and and cement
CO in factory's waste gas2Trapping combines, and process costs are relatively low, high financial profit.
Specific embodiment
