Technical Field

The invention relates to a mobile demineralized water production plant developed to meet this pure water need in areas that need pure water such as power plants, refineries, textile industry, coating industry, food industry, metal industry.

State of the Art

Different types of water are needed for each production process in industries. Depending on the source and purpose of use of the water, different purification methods and plants are used to meet this water need. Pure water (demineralized water) is indispensable especially for steam turbines, boilers and process waters. Demineralized water production is carried out in two ways, ion exchanger (fluidized bed) and reverse osmosis. In reverse osmosis, by applying a counter pressure above the osmotic pressure of the water, the water is separated from its dissolved salts by passing through the semi-permeable reverse osmosis membranes and thus it is purified.

Considering the current practices in power plants, fixed water purification plants are established within the power plant in order to supply pure water to the boilers in the power plants. These plants are designed and served according to the water flow required during the operation phase of the power plant. The most critical issue in power plants is the production of pure water and feeding it to the boilers in order to produce energy. Unless sufficient pure water is produced for the process (boilers), energy cannot be produced in the power plant. In power plants, there are two problems in particular. One of them is the problems that arise in the installation of the purification plant during the establishment and commissioning of the power plant, and the failure of the power plant to be put into operation as a result of the failure to carry out the boiler washing pass necessary for the commissioning of the power plant. Another issue is that, since the installed plant capacities are designed according to the water flow rate that the power plant will consume in operation, and because boiler washing requires much more water than these flow rates, additional pure water is needed even if the existing water purification is operating. Unless these issues are resolved, the commissioning of the power plant is delayed and serious financial losses occur.

Today, many studies have been carried out in order to eliminate the problems experienced in fixed pure water production plants and to establish additional plants quickly and easily in case of need, and as a result of these studies, mobile purification plants and mobile pure water production plants have been developed. One of the studies carried out is the invention that is the subject of the patent application TR 2017/04989 with the title "Mobile Adblue Production Plants". The invention relates to mobile adblue production plants, which are a complete heat/steam plant developed for the production of adblue in a portable container, at the desired location, and also contain equipment and devices capable of producing heating water, utility water or steam. In particular, the invention relates to the steam boiler that heats the pure water in the AdBlue production reactor by producing steam, and the mobile adblue production plants containing an osmosis purification system that produces pure water for the AdBlue production reactor from mains water, and an AdBlue production reactor that produces AdBlue by reacting by mixing urea and pure water with a urea mixer.

Another study is the invention that is the subject of the utility model application CN20042016140U with the title "Mobile Water Purifier". The invention is to provide a water purification device characterized by a water tank truck being connected in series with a water pump, a primary filter, a reverse osmosis membrane/filtering membrane component and a water storage tank. The device is essentially a mobile pure water plant that can filter heavy metal, organic matter and bacterial virus in the water to produce pure water that is more suitable for human use without the limitation of natural conditions such as water source. The invention can provide sufficient drinking water to the field team or field operation personnel at any time and anywhere. The invention technically achieves the transition from a fixed form pure water device to a mobile pure water device in order to enable the armies to drink normal water in case of field work or disaster relief activities. Another study is the invention that is the subject of the patent application CN201810110223 with the title "Multi-Stage Purification and Buffering Mobile Water Purifier". The invention describes a multi-stage purification and buffering mobile water purifier. Multi-stage purification and buffering mobile water purifier consists of a support base, a water purification main body, a raw water tank and a pure water tank; wherein the raw water tank is arranged in the upper part of the main water purification system. The support base is arranged at the bottom of the water purifier main body; a temperature display screen and a pure water tank are respectively arranged on the right side of the water purification main body; the water purifier main body is internally provided with a first core filter core drum, a second core drum and a third core filter core drum in turn from left to right; the first core drum, the second core drum, and the third core drum are provided internally and opposingly with titanium core filter plates; silica gel sealing rings are also embedded in the outer rings of the titanium core filtering plates, a plurality of elastic supporting columns are arranged on the outer sides of the two titanium core filter plates, respectively; the other ends of the elastic support columns rest on the sealing caps; fillers are arranged between two titanium core filter plates. The multi-stage purification and buffered mobile water purifier disclosed by the invention can be used repeatedly after cleaning; reduces the number of micro pollutants in the water body, the water purification effect can be improved and the service life extended.

Another study is the invention that is the subject of the utility model application CN201721194750U with the title “Pure Water Production Equipment”. The invention relates to a pure water production equipment, including a pretreatment device, booster pump, ultraviolet lamp device, ion exchange column and pure water collection box, the pretreatment device is two reverse osmosis membrane devices, the invention connected with the water inlet raceway of the reverse osmosis membrane device and the distribution port of the water pipe, and it explains that two reverse osmosis membrane devices are installed, that the process speed is increased in advance, that the preconditioning time is shortened, that the production efficiency of high-purity water is endure, and that the booster pump is installed at the same time.

In this detailed description, the mobile demineralized water production plant (100) developed to meet this need for pure water in areas where pure water is needed such as power plants, refineries, textile industry, coating industry, food industry, metal industry, which is the subject of the invention, is described only as an example for a better understanding of the subject and without any limiting effect. The subject of the invention is a mobile demineralized water production plant (100) to meet this pure water need in areas that need pure water such as power plants, refineries, textile industry, coating industry, food industry, metal industry characterized in that the demineralized water production system based on membrane processes to produce ultra-pure water at high capacity (300) comprises a body (200) with terminal points on it to make water inlets and outlets to the demineralized water production system (300) positioned inside, which can be transported by standard transportation routes (land and sea) for pure water production at the desired location without an additional building.

The mobile demineralized water production plant (100), shown in Figure-1, consists of a demineralized water production system (300) capable of producing ultrapure water and high-capacity water, and a body in a portable container structure (200) for mobile use. The body (300) used is a standard 40 ft HC (High Cube) container. In this way, it can be easily transported to any location with standard transportation routes (land and seaway). In addition, thanks to the container structure of the body (200), there is no need for an additional building, and it can be placed at a suitable point in the outdoor environment. However, thanks to the terminal points located on the body (200), water inlets and outlets to the demineralized water production system (300) can be easily made with flanged connections, and long and fixed lines are not required. The mobile demineralized water production plant (100), which is the subject of the invention, and the demineralized water production system (300), which consists of many process equipment and can produce high-capacity and ultra-pure water, are brought together in the body (200), and the use without assembly and installation is provided wherever pure water is needed, regardless of the location. In the demineralized water production system (300) based on membrane processes, in the mobile demineralized water production plant (100), which is the subject of the invention, a mechanical filter (302) positioned in the raw water inlet line as a pre-treatment unit and multi-media filters (303) were used to filter the settleable suspended solids in the water and produce a clear water. Said mechanical filter (302) and multi-media filters (303) provide physical purification of water before membrane processes. As membrane processes, first pass reverse osmosis unit (308) and second pass reverse osmosis unit (309) and EDI (electrodeionization) unit (310) were used in the demineralized water production system (300). Said first pass reverse osmosis unit (308) and second pass reverse osmosis unit (309) ensure that water is separated from its dissolved salts by passing through semi-permeable reverse osmosis membranes and thus purified by applying a counter pressure above the osmotic pressure of the water. Lime precipitation of the membranes in the first pass reverse osmosis unit (308) and the second stage reverse osmosis unit (309), an antisealant dosing unit (306) is positioned at the entrance of the first pass reverse osmosis unit (308), which gives antisealant to the water, in order to protect it against free chlorine and organic substances. The EDI (electro deionization) unit (310) is a specific technique used in the preparation of high purity water. While preparing pure water, electricity is used instead of chemical inputs. One of the most important features of the EDI (electrodeionization) unit (310) is that it does not generate wastewater during operation, and it is nature-friendly and environmentally friendly. With the mentioned membrane processes, the conductivity of the water is gradually reduced and pure water is produced. Since membrane processes do not need regeneration, continuous pure water production can be realized. In the said demineralized water production system (300), in addition to the mechanical filter (302) and the multi-media filter (303), there is a cartridge filter (307) positioned after the antisealant dosage unit (306), made of PP (polypropylene) material, which keeps all rust, sediment, particles, sand and similar substances inside its body and purifies the water in the desired microns. CIP (Clean in Place) unit (311) was used, which provides cleaning in the pure water production line in order to eliminate the pollution in pure water production. The raw water NaOCI dosing unit (301) is positioned in order to oxidize the iron and manganese that may be present in the water and to disinfect the water in the raw water entering the demineralized water production plant (300). In order to eliminate the negative effect of chlorine in the water (NaOCI) on the membrane, there is an SMBS dosing unit (305) that neutralizes chlorine by dosing sodium SMBS (sodium metabisulfite) to the water with a chemical dosing pump. The SMBS dosing unit (305) also prevents the growth of microorganisms that may cause organic pollution. In order to adjust the pH of the raw water and to optimize the carbonate precipitation on the membranes, there is even an acid dosing unit (304) that gives acid.
