Zero-carbon-emission cement production device and production method based on hydrogen energy utilization
The invention discloses a zero-carbon-emission cement production device and method based on hydrogen energy utilization. The production device comprises a hydrogen production system, a fuel cell system, a waste heat recovery system, a cement clinker calcination decomposition furnace system, a cement clinker calcination rotary kiln system, a grinding system and a methanol synthesis system. According to the invention, hydrogen is used for partially replacing kiln firing fuel, so that carbon emission reduction can be effectively realized at lower transformation cost without changing the existing cement production line process technology basically. Aiming at the problems of high energy consumption and high carbon emission in the cement industry, material flow and energy flow in the whole cement production process are optimized, so that the recycling of materials and the gradient utilization of energy are realized, and the low-carbon and environment-friendly properties of the whole set of production method are ensured.
本申请公开了一种基于氢能利用的零碳排放水泥生产装置及生产方法，所述生产装置包括：制氢系统、燃料电池系统、余热回收系统、水泥熟料煅烧分解炉系统、水泥熟料煅烧回转窑系统、粉磨系统和甲醇合成系统。本申请使用氢气部分替代窑炉烧成燃料，可以基本不改变现有水泥生产线工艺技术，能够在较低改造成本下有效的实现碳减排。针对水泥行业能耗高、碳排放高的问题，通过对水泥生产全过程的物流、能流优化，实现了物质的循环使用和能量的梯级利用，保证了整套生产方法的低碳、环保性。
