Description
技术领域technical field
本实用新型涉及饮用水的制备装置，具体涉及一种船舶饮用水的制备装置。The utility model relates to a preparation device for drinking water, in particular to a preparation device for drinking water for ships.
背景技术Background technique
目前，随着船舶运输业的发展，大型的离岸船舶数量越来越多，远程航行、长期离岸呈现常态化。此类船舶上的饮用淡水主要由供水船提供，并间歇性、一次性的将淡水大量储存于淡水箱中。由于长期储存，淡水箱清理不及时，会快速滋生大量细菌。稍有不慎，会对船舶人们的健康造成巨大的威胁。由于船舶空间狭小，无法容纳大型的净化水装置。此外，不同水域水质变化波动较大，常规的净水装置无法满足船舶生活饮用水的需求，因此开发一种用于船舶饮用水的制备装置非常重要。At present, with the development of the shipping industry, the number of large offshore ships is increasing, and long-distance sailing and long-term offshore are becoming normal. Drinking fresh water on such ships is mainly provided by water supply ships, and a large amount of fresh water is stored in fresh water tanks intermittently and once. Due to long-term storage, if the fresh water tank is not cleaned in time, a large number of bacteria will quickly grow. A little carelessness will pose a huge threat to the health of the ship's people. Due to the narrow space of the ship, it is impossible to accommodate large-scale water purification devices. In addition, the water quality in different waters fluctuates greatly, and conventional water purification devices cannot meet the needs of domestic drinking water for ships. Therefore, it is very important to develop a preparation device for drinking water for ships.
柱式超滤膜装置是以超滤膜为核心产品，利用多孔材料的拦截能力，以物理截留的方式去除水中一定大小的杂质颗粒。在压力驱动下，溶液中水、有机低分子、无机离子等尺寸小的物质可通过纤维壁上的微孔到达膜的另一侧，溶液中菌体、胶体、颗粒物、有机大分子等大尺寸物质被截留，从而达到筛分溶液中不同组分的目的。相较于其他超滤膜产品，柱式超滤膜装置拥有占地面积小的优势，非常适用于船舶饮用水的制备上。The column type ultrafiltration membrane device is based on the ultrafiltration membrane as the core product, and uses the interception ability of porous materials to remove impurity particles of a certain size in the water by physical interception. Driven by pressure, small-sized substances such as water, organic low molecules, and inorganic ions in the solution can reach the other side of the membrane through the micropores on the fiber wall, and large-sized substances such as bacteria, colloids, particles, and organic macromolecules in the solution The substance is retained, so as to achieve the purpose of sieving different components in the solution. Compared with other ultrafiltration membrane products, the column type ultrafiltration membrane device has the advantage of small footprint, which is very suitable for the preparation of drinking water for ships.
实用新型内容Utility model content
实用新型目的：本实用新型的目的在于解决目前船舶尤其是远洋货轮卫生饮用水短缺的问题，提供一种船舶饮用水的制备装置。Purpose of the utility model: The purpose of this utility model is to solve the problem of shortage of sanitary drinking water for ships, especially ocean-going cargo ships, and to provide a preparation device for drinking water for ships.
技术方案：一种船舶饮用水的制备装置，该装置包括取水箱、进水泵、粗格栅、介质过滤器、柱式超滤膜装置、膜电容去离子单元、反渗透装置、紫外光灭菌箱和饮用水池。Technical solution: A device for preparing drinking water for ships, which includes a water intake tank, an inlet pump, a coarse grid, a media filter, a column ultrafiltration membrane device, a membrane capacitive deionization unit, a reverse osmosis device, and ultraviolet light sterilization Tanks and drinking water pools.
在进水口处设有粗格栅，去除水源中的大型悬浮物。进水泵将粗格栅过滤后的水源输送到介质过滤器中，其出水再通过管道输送到柱式超滤膜装置，之后依次连接膜电容去离子单元、反渗透装置、紫外光灭菌箱和饮用水池。柱式超滤膜装置为膜电容去离子单元作预处理，它可以去除海水中的有机物，减缓膜电容去离子单元的膜污染问题。由于膜电容去离子单元脱盐效果快，但出水水质不稳定，所以在膜电容去离子单元后面安排反渗透装置，可以保证整个装置的水质。为了对水质进行杀菌，在反渗透装置和饮用水池之间设有紫外光灭菌箱。There is a coarse grille at the water inlet to remove large suspended solids in the water source. The water inlet pump sends the water source filtered by the coarse grid to the media filter, and the outlet water is sent to the column ultrafiltration membrane device through the pipeline, and then connected to the membrane capacitive deionization unit, reverse osmosis device, ultraviolet light sterilization box and Drinking pool. The column ultrafiltration membrane device is used for pretreatment of the membrane capacitive deionization unit, which can remove organic matter in seawater and slow down the membrane fouling problem of the membrane capacitive deionization unit. Since the desalination effect of the membrane capacitive deionization unit is fast, but the effluent water quality is unstable, a reverse osmosis device is arranged behind the membrane capacitive deionization unit to ensure the water quality of the whole device. In order to sterilize the water quality, an ultraviolet light sterilization box is installed between the reverse osmosis device and the drinking water pool.
本实用新型采用的介质过滤器的滤料为石英砂、活性碳、无烟煤、锰砂中至少一种。该介质过滤器能有效的截留除去水中的悬浮物、有机物、胶质颗粒、微生物、氯、嗅味及部分重金属离子等，此外，活性碳、无烟煤还有脱臭的作用。此装置为后续的超滤装置、膜电容去离子单元和反渗透装置作预处理。The filter material of the medium filter adopted in the utility model is at least one of quartz sand, active carbon, anthracite and manganese sand. The media filter can effectively intercept and remove suspended solids, organic matter, colloidal particles, microorganisms, chlorine, smell and some heavy metal ions in water. In addition, activated carbon and anthracite also have the function of deodorization. This device is used as pretreatment for the subsequent ultrafiltration device, membrane capacitive deionization unit and reverse osmosis device.
为了更好地净化水质并考虑到船舶的船舱空间狭小的实际状况，采用柱式超滤膜装置，该装置的膜材料为PVDF、PVC、PP中的一种。该装置还含有水力反冲洗装置，冲洗时间为20～180s，以减小超滤膜两端压差，恢复净化功能。In order to purify the water better and take into account the actual situation of the narrow cabin space of the ship, a column ultrafiltration membrane device is used. The membrane material of the device is one of PVDF, PVC and PP. The device also includes a hydraulic backwashing device with a flushing time of 20-180s to reduce the pressure difference between the two ends of the ultrafiltration membrane and restore the purification function.
为了去除海水中的盐离子，采用的膜电容去离子单元由多个膜电容去离子装置并联组成，膜电容去离子装置中部设置绝缘隔网，以绝缘隔网为中心，由绝缘隔网向两侧分别依次对称排布离子交换膜、纤维毡、石墨集流体和绝缘隔板。In order to remove salt ions in seawater, the membrane capacitive deionization unit used is composed of multiple membrane capacitive deionization devices connected in parallel. The middle part of the membrane capacitive deionization device is provided with an insulating grid, with the insulating grid as the center, from the insulating grid to the two sides. The ion exchange membrane, the fiber felt, the graphite current collector and the insulating separator are arranged symmetrically in sequence.
有益效果：与现有技术相比，本实用新型通过柱式超滤膜装置和膜电容去离子单元的结合使用，同时与介质过滤器和反渗透装置共同使用进行饮用水的制备，为长期远洋漂泊在水上的船民提供了卫生的饮用水，满足了船舶人们的用水需求。Beneficial effects: Compared with the prior art, the utility model is used in combination with the column type ultrafiltration membrane device and the membrane capacitive deionization unit, and is used together with the media filter and the reverse osmosis device to prepare drinking water. The boat people floating on the water provided sanitary drinking water to meet the water needs of the boat people.
