辽宁省某生活垃圾焚烧发电厂暖通设计
HVAC design for a municipal solid waste incineration plant in Liaoning province
摘要：
重点介绍了垃圾池间和卸料大厅的热风供暖措施,结合项目特点介绍了渣池间通风、新风系统和蓄电池室空调通风的设计,并探讨了利用冷却水余热的溴化锂热泵供热系统的经济性及可行性。结果表明,垃圾池间暖风系统采用多管淹埋式送风装置能自动适应垃圾堆料面变化,达到最佳的热风供暖效果。锅炉风机采用多支路防臭抽风系统,能有效地防止垃圾池间和卸料大厅的臭气扩散,又能减少大量抽风造成的加热量浪费。冬季从锅炉间补充热风可改善渣池间的能见度和环境温度,且不影响锅炉间供暖效果。房间及走道需要设计合理正压值,新风取风口和污染源须保持足够距离,可减轻臭气的影响。蓄电池室空调通风设计时需要充分考虑防爆及温湿度工况。溴化锂热泵方案的经济性分析需要考虑供热量、冷却水温度对汽轮机发电效率的影响。
Abstract：
This paper focuses on the heating measure using hot air in the waste pit and the unloading hall,and presents the design of the ventilation and the outdoor air system in the slag room,the air conditioning and ventilation in the battery room according to the characteristics of the project,and discusses the economy and feasibility of the lithium bromide heat pump heating system using the waste heat of cooling water.The results show that the warm air system in the waste pit uses the multi-pipe submerged air supply device which can automatically adapt to the change of waste material surface,to achieve the best hot air heating effect.The boiler fan adopts the multi-branch deodorant pumping system which can effectively prevent the diffusion of odor in the waste pit and the unloading hall,and reduce the heat waste caused by excessive air intake.In winter,adding hot air from the boiler room to the slag room can improve the visibility and ambient temperature,and does not affect the heating effect of the boiler room.The room and corridor should be designed with reasonable positive pressure values,and the outdoor air outlet and the pollution source should be kept enough distance to reduce the impact of odor.When designing the air conditioning and ventilation for the battery room,it is essential to thoroughly consider explosion-proof measures and temperature-humidity conditions.The economic analysis of lithium bromide heat pump scheme needs to consider the influence of heating quantity and cooling water temperature on the power generation efficiency of the steam turbine.
