Environment-friendly and energy-saving lime sintering process
The invention discloses an environment-friendly and energy-saving lime sintering process, and relates to the field of lime production processes, in the lime sintering process, lime is formed after limestone is roasted, and waste heat of flue gas is fully utilized to carry out waste heat treatment on the limestone in the production process of the lime sintering process, so that energy consumption is effectively reduced, and the purpose of saving energy is achieved. The flue gas is treated by a purification device after being used and before being discharged into the atmosphere, the flue gas is firstly fully reduced into harmless substances under the action of reducing gas and a reaction catalyst when passing through the purification device, then the harmless substances are adsorbed by an adsorption filter element, more than 90% of harmful gas can be removed, and the purified flue gas finally enters a spray tower to be treated. And through spraying of the spraying water, harmful gas is further removed, so that the exhausted flue gas is effectively purified, and a good environment-friendly effect is achieved.
本发明公开了一种环保节能的石灰烧结工艺，涉及石灰生产工艺领域，该石灰烧结工艺中，石灰石经过焙烧后形成石灰，在其生产过程中充分利用烟气的余热对石灰石进行余热，使得降低了能源消耗得到有效的降低，达到了节能的目的，而烟气利用之后排入大气之前，经过净化装置处理，烟气经过净化装置时首先在还原性气体以及反应催化剂的作用下充分还原成无害物质，之后再经过吸附滤芯吸附，能够去除90%以上的有害气体，净化后的烟气最后进入喷淋塔处理，经过喷淋水的喷淋，有害气体进一步去除，是的排除的烟气得到有效的净化，达到良好的环保效果。
