Special desalination equipment for sea going ships

Release date: 2020-03-29 21:49:18

Brief introduction of marine desalination equipment
Because the specified temperature of the special type seawater desalination equipment for container ships is relatively low, it is not easy to produce the structure and erosion of the inner cavity. The preparation of desalination equipment is very simple, and the ductility of the whole set of equipment is also very large. In the peak period, the water production rate of desalination equipment can exceed the design scheme value of machinery and equipment. In the low tide period, it can also show 40% of the fixed real estate water production rate. The driving power consumption of the whole set of machinery and equipment is low, which can reduce the cost of water treatment of machinery and equipment. The machinery and equipment of marine desalination equipment can be trusted, and there will be no mixing of concentrated water and commercial water The state of affairs.

Operation of special desalination equipment for container ships
The automatic control system design scheme of all RO reverse osmosis desalination equipment adopts the excellent electronic computer system control in the world. The PLC of industrial computer practical operation station constitutes an automatic control system of decentralized sampling operation and centralized monitoring of actual operation. According to the basic processing parameters, high-pressure and low-pressure overload protector, automatic conversion equipment, when conductivity, total flow and working pressure are abnormal, it can maintain full-automatic conversion, full-automatic interlock alarm and shutdown, so as to maintain high-pressure water pump and RO reverse osmosis membrane components.
Concrete filtration of machinery and equipment of special type seawater desalination equipment for container ships
The concrete filter is dedicated to remove colloidal solution and floating residue in the sea surface to reduce turbidity. In RO reverse osmosis membrane separation project, the pollution index (FI) is generally used to measure and verify, and the fi value of water supply and drainage into the RO device is required to be less than 4. Because of the large proportion of sea surface, high pH value and large periodic temperature change, the system software uses FeCl3 as coagulant aid, which will not be harmed by temperature, alum bloom is large and firm, and settlement speed is fast.
It is composed of two layers of filter material filter and activated carbon filter. Two sets of two-layer mechanical filter and two sets of activated carbon filter are set respectively. The filtration rate is between 7 and 2m / s. The filter unit is lined with steel glue and coated with marine paint. ABS water cap and 316L stainless steel pipe are arranged under the filter. In order to reduce the sea surface preparation system software and instantaneous load, and improve the water utilization rate, the RO RO reverse osmosis extraction water is set as the vapor-liquid softener system software of the filter device backwash water.
