Zinc electrolyte cooling acid mist treatment tower

Abstract

The invention relates to a zinc electrolyte cooling acid mist treatment tower, belonging to the technical field of cooling tower. The zinc electrolyte cooling acid mist treatment tower is provided with a tower body. A circulating liquid spray device is installed in the tower body. A liquid collection partition plate which horizontally partitions the tower body is arranged in the tower body at a position above the circulating liquid spray device. A neutralizing liquid outlet is arranged on the tower body above the liquid collection partition plate at a position close to the liquid collection partition plate. A plurality of ventilation pipes which can enable gas below the liquid collection partition plate to flow to a position above the liquid collection partition plate are arranged on the liquid collection partition plate. A liquid retaining cap is respectively and fixedly arranged above each ventilation pipe. A gas flow passage is arranged between each liquid retaining cap and each ventilation pipe. A packing layer is arranged above the liquid retaining caps. A neutralizing liquid spray device is arranged above the packing layer. The invention has the advantages that the zinc electrolyte can be cooled, the wet and hot acid gas can be purified and the environmental pollution caused by the acid gas is avoided.

Description

technical field [0001] The invention relates to the technical field of cooling towers, in particular to a zinc electrolyte cooling acid mist treatment tower. Background technique [0002] The zinc electrolyte cooling tower usually includes a tower body, an axial flow fan, a spray pipe and a nozzle installed on the spray pipe. The axial flow fan is arranged outside the bottom of the tower body, and the nozzle is arranged in the upper tower body. It blows into the tower body from the bottom of the tower body and moves upward, and exchanges heat with the high-temperature zinc electrolyte sprayed by the nozzle in the tower body, and the hot and humid acid gas after heat exchange is directly discharged into the atmosphere. This hot and humid acidic gas is directly discharged into the atmosphere, polluting the environment. However, if gas purification equipment is used to treat the gas discharged from the zinc electrolyte cooling tower, due to the large structure of the zinc elec...
