The invention relates to a tubular-trough-type acid divider having a flow stabilizing apparatus. The acid divider enables liquid level of an acid dividing trough to be flat and stable, ensures uniform and constant acid outlet quantity at an acid outlet point, and has good acid dividing effect and high absorption rate. The acid divider includes an acid inlet pipe, an acid total pipe, a plurality of acid dividing branch pipes, a plurality of acid dividing troughs, a plurality of acid dropping tubes, and a plurality of flow stabilizing apparatuses. Each flow stabilizing apparatus includes buffer pots, flow stabilizing pots and flow stabilizing tubes in a symmetrical manner. The upper part of each buffer pot is communicated with the acid dividing branch pipes and the lower part is communicated with the symmetrical flow stabilizing pots. The flow stabilizing pots are disposed on the bottoms of the acid dividing troughs. The acid dropping tubes is arranged on the bottom of the acid dividing troughs respectively in two rows. The acid dropping tubes are connected to each other through two rows of the flow stabilizing tubes which are arranged on the bottom of the acid dividing troughs.
