以煤球造气方法生产碳氨,是目前小氮肥工业采用的生产工艺.生产过程中有大量废液排出,其中水洗塔工艺流程中排出的废水,尚具有很大的能量,充分利用这些能量,化废为宝,是小氮肥工业利用三废,节约能源,增加收入的一个大有作为的项目.煤球造气生产工艺流程中,所产生的高压硫化氢气体,需进行水浴化学处理,此项处理系在密闭的水洗塔中,在具有10～14公斤/厘米~2气体压力条件下进行,经过水浴后的废水,它经过减压阀减低
The production of carbon ammonia by briquette gas production method is the production technology adopted by the small nitrogen fertilizer industry at present.A large amount of waste liquid is discharged during the production process and the waste water discharged from the process tower of washing tower still has great energy and full use of these energies, Waste of waste for the treasure, is a small nitrogen fertilizer industry to use three wastes, energy conservation, increase revenue a great undertaking of the project. Briquettes gas production process, the generated high-pressure hydrogen sulfide gas, water bath chemical treatment required, this treatment in Airtight washing tower, with 10 ~ 14 kg / cm ~ 2 gas pressure conditions, after the water bath waste water, it is reduced through the valve
