The structure of the spray-type saturator has the following characteristics: ① The spray chamber consists of a main body, an outer sleeve, and an inner sleeve. After entering the main body, the gas flows downward within the annular space between the main body and the outer sleeve; it then exits the spray chamber from the top and enters the space between the outer sleeve and the inner sleeve in a tangential direction, flowing downward into the inner sleeve before exiting from the top. A cyclone separation effect is created between the outer sleeve and the inner sleeve to remove the liquid droplets carried in the gas, serving as an acid remover. ②A mother liquor full-flow tube is installed at the lower part of the spray chamber to control the liquid level there, thereby facilitating the flow of gas from the inlet to the outlet within the annular chamber. ③Two arc-shaped distribution boxes are arranged between the gas inlet and the gas outlet; multiple sets of nozzles are installed in these arc-shaped distribution boxes, with their directions pointing toward the gas flow, thereby creating an effective gas-liquid contact surface. ④The lower part of the spray chamber is a crystallization tank, which is connected to the crystallization tank via downcomers. The circulating mother liquor rises from the bottom of the crystallization tank through these downcomers. The newly formed ammonium sulfate nuclei pass through the upward-moving suspended ammonium sulfate liquor, which promotes the growth of the crystals and leads to particle separation – with the smaller particles rising to the top and being sent to the circulation pump via the upper outlet, while the crystals are extracted from the lower part. ⑤A mother liquor spraying device is installed at the gas outlet. Both the gas inlet and outlet are equipped with warm water spraying devices, which allow for a thorough cleaning of the spray chamber. In summary, the spray-type saturator process combines the advantages of the traditional saturator method, such as its simple operation, with those of the acid washing method, including high-volume mother liquor circulation and agitation as well as larger crystal particles. It also overcomes the disadvantages of the traditional saturator method, namely high resistance in the gas system, and those of the acid washing method, such as a long process flow and numerous pieces of equipment. Its process flow and operating conditions are similar to those of existing bubble-type saturators, making it easy to master, and the equipment materials can be sourced domestically. It can be used not only in new factories but is also more suitable for major renovations of existing factories
