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.
Description
technical field [0001] The invention relates to a sulfuric acid production equipment, in particular to a drying tower and an absorption tower of a sulfuric acid production system, which are used for pyrite acid production, flue gas acid production, sulfur acid production and low-temperature waste heat recovery. The tube-trough acid distributor of the steady flow device. Background technique [0002] In the system equipment for producing sulfuric acid, the acid distributor is an important component in the drying tower and absorption tower. The concentrated sulfuric acid flowing down and the process gas flowing upward from the bottom of the tower are uniformly contacted in the packing layer, and the concentrated sulfuric acid dries and absorbs sulfur trioxide in the process gas to form sulfuric acid with a higher concentration. The gas absorption rate of the acid distributor directly affects the normal operation of the whole system. A low absorption rate will lead to excessiv...
