Description

Technical Field

[0001] This invention relates to the field of drying technology, and in particular to a wire mesh defoaming device and its drying tower. Background Technology

[0002] A wire mesh demister is a high-efficiency gas-liquid separation device, often built into the top of gas-liquid contact equipment such as drying towers. Its core function is to capture liquid droplets entrained in the gas flow, preventing the droplets from being discharged with the gas and affecting the drying effect or causing material loss. Chinese patent application number 202410894045.1 discloses a sulfuric acid drying tower, including a tower body. The tower body is provided with an exhaust port, a baffle plate demister, an atomizing spray device, a sulfuric acid feed port, multiple layers of tower plates, a gas inlet, and a sulfuric acid outlet from top to bottom. The tower plate is characterized by having multiple gas outlet pipes, with bubble caps fixedly connected to the upper part of each gas outlet pipe. The bubble caps are provided with serrations. The area of ​​a single serration on the bubble caps installed on the top two tower plates is 1 / 4 to 3 / 4 of the area of ​​a single serration on the bubble caps installed on the third to Nth tower plates. The reduction in the size of the slits in the bubble cap of this invention creates a pressure difference between the gas between the upper two layers and the gas between the lower layers. The reduced area of ​​the slits allows the gas to be sprayed more finely and farther when passing through the slits, while also increasing the contact area with concentrated sulfuric acid. The gas is then guided back to the bottom tray for secondary drying, thus improving the drying effect.

[0003] However, this sulfuric acid drying tower also has some problems. For example, although the baffle plate demister increases the ventilation and demisting area through its folded structure, due to its structure, the filtered and collected droplets can only be discharged downwards by gravity, resulting in low demisting efficiency. Moreover, some droplets cannot drip down for a long time due to viscosity and other reasons, which affects the operation of the device. Summary of the Invention
