DCH series soft water system is a new environmentally friendly, economical and safe new soft water treatment system method developed by our company according to national industry standards and a large number of successful engineering practice experiences. Based on the design principle of end users, combined with raw water pretreatment, water quality monitoring and distribution system, and selection of adaptive equipment to form a fully automatic sodium ion exchange soft water system. The problem of high operating cost, frequent equipment failure, unqualified water quality, and mismatch of water quality and user demand caused by the user's previous use of the water softener has been completely solved. It has been widely recognized by users all over the country and is the best choice for customers. Introducing the world's most advanced American FLECK company and the US AUTOTROL company control device, the domestic fully assembled ion exchange softening water equipment, combined with the actual situation in China, the integration of advanced manufacturing technology and technology at home and abroad, the resin tank is made of high quality glass steel, stainless steel It is made of anti-corrosion materials such as carbon steel lining plastic. It has excellent equipment quality, stable and reliable performance, realizes fully automatic operation of softened water equipment, no need for special management, and its performance price ratio is higher than domestic similar products. It is widely used throughout the country with good effect. . The system is widely used in boilers, air conditioning and refrigeration systems for industrial or civil systems such as petrochemical, light industrial textiles, food hygiene, hotels and restaurants. System selection The first step: system parameter data analysis The second step: system solution selection The pretreatment system, softening treatment system, water quality monitoring system, water hardness adjustment system, and water supply system are composed of five parts. The third step: softening the exchanger calculation 1 exchanger diameter 2 exchanger height 3 backwash flow orifice plate 4 jet 5 salt tank water injection 6 salt tank water injection orifice plate 7 resin model and configuration Part IV: Determining the system plan Technical Parameters 1. Raw water hardness: primary sodium: < 8mmol/L secondary sodium: ≥8mmol/L 2, water hardness: steam boiler standard ≤ 0.03mmol / L or according to user requirements, respectively, to meet the needs of different uses. 3. Water quality requirements: Inlet water temperature 5°C-45°C Ambient temperature 5°C-50°C Inlet suspension < 5mg/L; inlet iron content < 0.3mg/L Inlet water pressure 0.2mpa – 0.5mpa; inlet free chlorine ≤0.3mg/L 4, the power supply voltage: 220V ± 10; 50HZ 5. Resin: Strong acid cation exchange resin. 6, regeneration control: time, flow. 7, salt consumption: < 100g / mmol 8, interface type: thread or flange 9. Water hardness detection alarm point (optional, sound and light alarm) can adjust the alarm range according to the water quality requirements of the customer system. 10, monitoring cycle: 2 minutes - 120 minutes (optional) 11, sensor: calcium ion selection electrode (optional) 12, valve body material (lead-free brass, engineering plastics) 13, tank material (glass steel, stainless steel, etc.) 14, resin type (general grade, food grade) Technical characteristics 1, perfect system design (cost-effective) The system needs, matches reasonably, online monitoring, and economic stability. 2, automatic control (stable, simple) Automatic water supply, backwashing, salt absorption, replacement, washing, hydration, and stable operation. 3. Low energy consumption (energy saving, environmental protection) Self-consumption water consumption < 2% water production, salt consumption < 100g/mmol, power consumption 10W - 40W. 4, flexible design selection (targeted) Optional single tank, multi tank system, time, flow, control mode. One use one, two use one, alternate regeneration, can be connected in series, parallel and other modes of operation. 5, large flow range (wide range of applications) The water production capacity of single tank is 1-200m3/h, and the water production capacity of double tank is 1-400 m3/h. 6, multi-function brine control system (reliable) It can automatically dissolve salt, absorb salt and adjust salt level to ensure reliable automatic regeneration. Raw water quality impact system solution 1. When the original water suspension is >5mg/L, a high-precision filter should be installed in front of the water softener to prevent resin contamination; 2, the original water iron, manganese content>0.3mg / L, 0.1mg / L need to be equipped with iron and manganese equipment in front of the water softener to prevent resin iron, manganese poisoning; 3. When the free chlorine content of raw water is >0.3mg/L, it is necessary to equip the water softener with chlorine removal equipment to prevent the resin from being contaminated; 4, the original water salt content <500mg / L, hardness <6.5mmol / L, choose a primary sodium ion exchanger; 5. When the raw water has a salt content of 500 to 1000 mg/L and a hardness of 6.5 to 10 mmol/L, a secondary sodium ion exchanger is selected; 6. When the salt content of raw water is >1000 mg/L, or the hardness is >10 mmol/L, electrodialysis and first-stage sodium ion exchanger are selected.
