船舶作为国际物流交易的主要交通工作，控制废气排放在环境保护中起着非常重要的作用，整个脱硫塔装置操作简单，成本有效，维护方便，可适用于任何类型的船舶，与所有类型的发动机兼容，同时减少硫排放对海洋生物保护也起着至关重要的作用，脱硫塔在废气处理和生物脱硫中可以完全满足船舶工业限制硫排放的要求。
As the main traffic work of international logistics transactions, ships play a very important role in environmental protection by controlling exhaust emissions. The entire desulfurization tower device is simple to operate, cost-effective, and easy to maintain. It can be applied to any type of ships, and is compatible with all types of engines. At the same time, reducing sulfur emissions also plays a vital role in marine biological protection, Desulfurization tower can fully meet the requirements of limiting sulfur emission of marine industry in waste gas treatment and biological desulfurization.

(1)模块化装置。
(1) Modular device.
模块化设计使脱硫塔在安装过程中更加简单高效，大大降低了船厂的安装强度。同时，模块化设计缩短了整个系统的调试时间，有效地提高了安装效率，减少了停机时间。整个系统具有独特的集成解决方案，可同时完成冷却废气、去除硫磺、消除粉尘颗粒等活动。同时，洗涤塔是一种开放的、无移动部件的结构，具有很高的稳定性和可靠性。洗涤塔的结构非常紧凑，也是定制的，可以有效匹配新建或改造的船舶有限的空间。
The modular design makes the installation of desulfurization tower more simple and efficient, and greatly reduces the installation intensity of shipyard. At the same time, the modular design shortens the debugging time of the whole system, effectively improves the installation efficiency and reduces the downtime. The whole system has a unique integrated solution, which can simultaneously complete activities such as cooling waste gas, removing sulfur, and removing dust particles. At the same time, the washing tower is an open structure without moving parts, with high stability and reliability. The structure of the washing tower is very compact and customized, which can effectively match the limited space of the newly built or rebuilt ships.

生物脱硫
Biological desulfurization
在整个系统中，洗涤塔是影响安装的核心部件。其尺寸取决于发动机的大容量，以保持其低能耗和低背压。如果一些船舶空间真的有限，洗涤塔的尺寸仍然可以调整。废气从洗涤塔底部引导至顶部。在此过程中，废气流量在塔内得到控制。海水通过塔顶喷嘴均匀地从塔顶喷出，形成均匀的喷雾，有效地清洗废气，包括三个有效的工程：
In the whole system, the washing tower is the core component that affects the installation. Its size depends on the large capacity of the engine to maintain its low energy consumption and low back pressure. If the space of some ships is really limited, the size of the washing tower can still be adjusted. The waste gas is directed from the bottom of the scrubber to the top. During this process, the exhaust gas flow is controlled in the tower. The sea water is evenly sprayed from the tower top through the tower top nozzle to form a uniform spray to effectively clean the waste gas, including three effective projects:
(1)冷却。排气管的尾气从排出到塔顶，通过两层喷雾处理，冷却到温度。
(1) Cooling. The tail gas from the exhaust pipe is discharged to the tower top, treated by two layers of spray, and cooled to temperature.
（2）消除粉尘颗粒。在清洗塔的过程中，塔内的喷雾有效地去除了几乎所有的颗粒粉尘。
(2) Eliminate dust particles. In the process of cleaning the tower, the spray in the tower effectively removes almost all the particulate dust.
（3）去除硫磺。在废气排放到大气中之前，废气中的SOX被塔顶的喷雾溶解，并以盐的形式排放到循环处理柜中。清洁废气从塔顶排出，硫化物通过喷雾去除。
(3) Remove sulfur. Before the waste gas is discharged into the atmosphere, the SOX in the waste gas is dissolved by the spray on the tower top and discharged into the circulating treatment cabinet in the form of salt. Clean waste gas is discharged from the tower top, and sulfide is removed by spray.
(3)闭环洗涤装置。
(3) Closed loop washing device.
闭环洗涤装置应用于零排放区，海水在洗涤过程中连续回收。工作原理过程如下：船舶尾气通过尾气收集器从洗涤塔底部进入顶部，通过洗涤塔内的两个均匀喷雾。废气在洗涤塔中用海水喷雾清洗，废气中的硫溶解在喷雾水中，处理后的水收集到处理后的水循环柜中，然后在循环柜中加入Naoh以中和酸度。处理后的水将再次输出到洗涤塔中，以便重复回收。循环硅中的硫化物将与Naoh化学反应成无机盐，一定量的工艺水将从系统中排出，并在工艺水处理系统中自动处理。同时，海水和Naoh将继续供应到处理水箱中，以保持处理水箱的液位和PH值，工艺水处理单元将分离出的污泥仓库，剩余的污泥将被吸入污泥仓库。VIMEPC.259(68)号决议将根据MARPOL(国际防止船舶污染的公约)继续监测PH值、浊度和PAH值。清洁废气将从洗涤塔排出，不含硫和灰尘颗粒。
The closed-loop washing device is applied to the zero discharge zone, and the seawater is continuously recovered during the washing process. The working principle is as follows: the ship exhaust enters the top from the bottom of the scrubber through the exhaust collector, and passes through two uniform spray in the scrubber. The waste gas is cleaned in the scrubber with seawater spray, the sulfur in the waste gas is dissolved in spray water, the treated water is collected in the treated water circulating tank, and then Naoh is added to the circulating tank to neutralize the acidity. The treated water will be output to the scrubber again for recycling. Sulfide in circulating silicon will react with Naoh to form inorganic salt, and a certain amount of process water will be discharged from the system and automatically treated in the process water treatment system. At the same time, seawater and Naoh will continue to be supplied to the treatment tank to maintain the level and PH value of the treatment tank. The process water treatment unit will separate the sludge warehouse, and the remaining sludge will be sucked into the sludge warehouse. Resolution VIMEPC.259 (68) will continue to monitor PH value, turbidity and PAH value according to MARPOL (International Convention for the Prevention of Pollution from Ships). The cleaning waste gas will be discharged from the scrubber without sulfur and dust particles.
