Attached efficiency declines problem, it is to avoid the wave production high-quality H of Ca-base adsorbent resource2、CO、C2H2While trapping whole system
CO2Gas, realizes resources effective utilization, sustainable utilization and recycling.
Technical scheme：The calcium carrier loop H of the present invention2-CO-C2H2Poly-generation cooperates with CO2Capture method, including following step
Suddenly：
1）Processing is modified to carbide slag slurries using ultrasound-removal of impurities-calcining-sieving technology, product is regard as Ca-base adsorbent；
2）Waste carbide slag is starched into modified obtained Ca-base adsorbent is used for hydrogen production from coal gasification, participates in reacted Ca-base adsorbent
With coke, in O2With under co-rich synthesis gas existence condition, calcination and regeneration and burning are carried out respectively, the calcium base absorption regenerated
Agent, while trapping CO2Gas；
3）The Ca-base adsorbent of the regeneration, part feeding gasification furnace, under CO and water vapor conditions, continues to complete coal gasification system
Hydrogen, sends into another part Ca-base adsorbent as calcium carbide preparing raw material in the hot method blast furnace of oxygen, calcium carbide is obtained, while obtaining rich CO
Synthesis gas；
4）By calcium carbide and water reaction generation C2H2Gas and accessory substance carbide slag slurries, by the step 3）Obtained co-rich synthesis gas
It is divided into three strands, the hydrogen production from coal gasification that a part is used in gasification furnace a, part is used to burn to provide heat, one in calcining furnace
Lease making crosses purifying and dedusting and obtains high-purity CO gases.
Further, in the inventive method, the step 2）In CO synthesis gas be the hot method blast furnace of oxygen in prepare calcium carbide
Accessory substance, concentration more than 90%.
Further, in the inventive method, the step 2）In the adsorbent calcining of generation burnt with coke, product is equal
For CO2Gas.
Further, in the inventive method, the step 3）In CO synthesis gas be the hot method blast furnace of oxygen in prepare calcium carbide
Accessory substance, concentration more than 90%.
The present invention realizes coal and is converted into H by the recycling of calcium carrier and two kinds of waste resources of carbide slag slurries2-
CO-C2H2The Poly-generation of gas, is that coal chemical industry has started a new way, coal is turned into clean energy resource.
Beneficial effect：The present invention compared with prior art, with advantages below：
1）Solve in the industrial discharge and process problem of waste carbide slag slurry, carbide slag slurries and contain substantial amounts of Ca (OH)2, propose
Using the ultrasonic method carbide slag slurries water removal more to water content, and then the magazine composition of carbide slag after drying is removed, by calcining
After screening, CaO solids are can obtain, the Ca-base adsorbent in coal gasification course is used it for, can under vapor existence condition
Obtain high-purity hydrogen；
2）The problem of adsorption efficiency is substantially reduced after Ca-base adsorbent is repeatedly circulated is solved, proposing will multiple reacted calcium base
Adsorbent（Adsorbent after calcining, main component is CaO）In the feeding blast furnace of part, the raw material prepared as calcium carbide.Adsorbent
The part of reduction is supplemented by fresh calcium carbonate, successfully solves the problem of Ca-base adsorbent efficiency is reduced；
3）In conventional art, using CaCO3CaCO under calcium carbide preparation, high temperature is carried out as raw material3More CO is produced after decomposition2
Gas, reduces the quality of aerogenesis in blast furnace so that CO concentration is greatly lowered in gas.Former % material are changed to after CaO, can be made
The standby CO gases for obtaining higher purity, theoretical concentration is up to 95%；
4）Co-rich synthesis gas are passed through gasification furnace, water-gas shift occurs in gasification furnace for CO gases, generates H2With CO2Gas, production
Raw CO2Gas is absorbed by the adsorbent of carbide slag modification again, therefore can improve the H of system2Yield；
5）The co-rich synthesis gas produced from blast furnace a, part is passed through in calcining furnace in O2Middle burning.It is unreacted in gasification furnace
Coke is same in O2Middle burning, so as to provide the heat of abundance for reactor.Its product is identical with the product after calcination of calcium carbonate,
It is CO2Gas, therefore, it can in the case where ensureing system thermal equilibrium condition, all CO that trapping system is produced in calcining furnace2
Gas.
6）Equally contain more pernicious gas COS in blast furnace in co-rich synthesis gas, after being passed into gasification furnace, gasification
CaO in stove just reacts with COS, reduces noxious gas emission.
