AI Technical Summary
In existing granulation tower spray dehumidification devices, the mist collection effect of flat plate demisters and folding plate demisters is poor, resulting in low dehumidification efficiency.
The system employs two symmetrically arranged demisting plates, each consisting of several parallel corrugated plates. The collection trough has three bends, forming a multi-directional structure that increases the chances of mist droplets being captured. Uncaptured mist droplets are repeatedly captured at the next bend.
It significantly improves the demisting efficiency, ensuring that the gas passing through the demisting mechanism is virtually free of mist droplets, thus enhancing the dehumidification effect.

TECHNICAL FIELD
[0001] The utility model relates to a spray dehumidification technical field, specifically a granulation tower spray dehumidification device. BACKGROUND
[0002] Spray dehumidification of flue gas is an important link in the flue gas treatment process. It mainly sprays water mist or fine water droplets into the flue gas through a spray device, and uses the heat absorption principle of water evaporation to reduce the temperature and humidity of the flue gas. The working principle of flue gas spray dehumidification is based on the heat and humidity exchange between water and flue gas. When water mist or water droplets come into contact with flue gas, water molecules will evaporate and absorb heat from the flue gas, thereby reducing the temperature and humidity of the flue gas. At the same time, the evaporated water vapor may also react with other components in the flue gas (such as sulfur dioxide and nitrogen oxides), further purifying the flue gas.
[0003] In the existing granulation tower spray dehumidification, the demister installed at the top of the tower usually includes a flat plate demister and a folded plate demister. The flue gas channel of the flat plate demister is a vertical straight channel, and the collision effect between the mist and the plate body is poor, so the demister has low mist capture efficiency. The internal flue gas channel of the common folded plate demister is a curved channel, but the number of bends is usually small. In use, some mist can easily pass through several turning points and cannot be liquefied, so the efficiency of this kind of demister is not high in actual use. Therefore, the above-mentioned problems are solved by the present application. SUMMARY
[0004] The technical problem to be solved by the utility model is to provide a granulation tower spray dehumidification device. The demisting mechanism in the spray dehumidification device is composed of two layers of symmetrical demisting plate layers. Each layer of demisting plate layer is composed of several pieces of parallel arranged wave-shaped plates. Three bending points are formed in the capture groove of each layer of demisting plate layer. Based on the above structure, the multi-fold structure in the demisting mechanism greatly increases the chance of mist being captured. The mist that has not been removed is captured at the next turning point through the same action. This repeated action can greatly improve the demisting efficiency. After the gas passes through the demisting mechanism, it is basically free of mist. The technical problem of low mist capture efficiency of the flat plate demister and the common folded plate demister in the prior art is solved.
