"Por favor, inform informe se se砂滤气体反冲洗过程是不是先开启反洗进气阀，再开启顶部排气阀，先用气体擦洗，然后再打开反洗进水阀，打开反洗排放阀排放废水。那问题是：气体反洗过程这个气量很大如果反洗进气阀是DN50气压5mH2O那这个气是不是只能从顶部排气阀出O那顶部排气阀也需要很粗的管道也需DN51你们排气阀口径是怎么定的呢？";

"Veja o anexo queo看附件，可以参考一下，气洗是从砂滤器底部进气顶部排气你说的DN5应该是砂滤器反洗进水管的管径气洗的进气管道可能与反洗管道连接到了一起用阀门控制。气洗的进气气源管道进出口管径应该是一致的或者差不多的。再有砂滤器的气洗管道没必要那么粗根据砂滤器的大小而定。";

"那砂滤器的处理量是多大的装的多厚的砂粒？";]
