- 1. Efficient resin recovery technology
Ion exchange resin (hereinafter referred to as resin) is poisoned by harmful impurities such as iron, organic matter, suspended matter, siliceous, microorganisms, heavy metals, etc. during the use process, and the resin is poisoned. These impurities cannot be completely removed by conventional methods, resulting in The exchange capacity of the resin decreased, and even the exchange effect was completely lost.
High-efficiency resin resuscitation technology is to use BM, CBA, ASB and other resuscitation agents, combined with ultrasound, to remove impurities and activate the poisoned resin. The recovery rate of the old resin can reach 99%, and the working exchange capacity and service life can reach the performance of the new resin; after the new resin recovers, the work exchange capacity and service life can be increased by 30-50%. It can save tree cost, reduce unit consumption of acid, alkali and industrial salt, and reduce “white pollution” caused by waste resin.
- 2. Active iron deoxidization technology at room temperature
The technology is to use active iron to remove oxygen in water supply at room temperature, and then use special resin to remove iron and impurities. After treatment, the feed water is at room temperature, its oxygen content, conductivity, hardness, silica, iron, copper and other indicators Can meet or even exceed the national standard of high-pressure boiler feedwater quality, the cost of water treatment per ton is only 0.2 yuan / ton. Using active iron deoxidization at room temperature instead of the original thermal deoxygenation, the direct benefit is to eliminate the waste of steam deaeration in the deaerator, and the energy saving of the boiler is 2 to 3%; , Reduce the energy consumption of water supply heating and solve the worldwide problem of low temperature waste heat recovery.

- 4.Efficient exhaust steam recovery technology
The multi-process longitudinal flow exhaust steam recovery technology we developed uses the heat exchange of normal temperature water (or materials) to recover exhaust steam heat energy. The equipment is highly efficient and compact, and has the following characteristics:
The exhaust steam recoverer can reach normal pressure or slightly negative pressure, which is beneficial to exhaust steam exhaust.
The operating pressure difference of the spent steam recycler is <0.2MPa, and there is no need to increase the power transmission.
The cold side medium is not in contact with the exhaust steam and is not contaminated by exhaust steam impurities.
The temperature of the medium on the cold side rises and the amount of spent steam recovered is large.
Unique internal structure design, no vibration or whistle during operation.
Different materials are used according to the nature of the medium and the exhaust vapor impurities to prevent equipment corrosion.
- 5. Double-flow anti-chaos layer mechanical filtration technology
The purpose of mechanical filtration is to remove suspended matter in raw water. The quartz sand in the traditional mechanical filter is arranged from large to small from bottom to top. The thickness of the quartz sand filler layer is about 1200mm. The raw water flows through the filter from top to bottom during operation. When the flow rate is too large, it is easy to cause the small quartz sand in the upper layer to leak downward, that is, the chaotic layer, the filtration resistance increases, the filtration effect becomes poor, and the suspended matter in the effluent is not guaranteed, which affects the normal operation of the resin bed.
The designed double-flow anti-chaos mechanical filter has a water production capacity that is 80 to 100% higher than that of a conventional mechanical filter of the same diameter, and no matter how large the backwash flow rate is, the packing will not be chaotic. The backwash time and backwash water volume are higher than traditional The mechanical filter is reduced by 75%, and the suspended solids content in the effluent is less than 1 mg / L.
- 6. Circulating water softening technology
The original process generally adopts hard water circulation, and the scale is inhibited by adding scale inhibitors and bactericidal algaecide. This method has problems:
Higher operating costs:
Condenser fouling is more serious: Due to the higher hardness of circulating water, even if the scale inhibition treatment is performed, the condenser fouling phenomenon is still widespread, not only affecting the heat exchange of the condenser, but also increasing the cleaning cost.
Low concentration of circulating water: Due to continuous evaporation, the hardness of circulating water increases. When the hardness increases to a certain degree, the circulating water must be replaced to increase the amount of waste water discharged. Circulating water softening technology is to use a new type of fixed bed softener to soften all supplementary water and part of the circulating water. Its characteristics are:
Low operating cost: The system does not increase power. Its operating cost is mainly the cost of supplementary water softening. Since the average replenishment rate of circulating water is less than 1%, the actual amount of supplemental water is very small and the softening cost is low. Taking the 6000 tons / hour circulating water system as an example, the supplementary water volume is less than 60 tons / hour, the supplementary water softening cost is 0.2 yuan (the raw water hardness is 3 mmol / liter), and the annual operating cost is less than 100,000 yuan (8000 hours per year ), 20-50% lower cost than the original process.
Prevent condenser fouling: softening of circulating water fundamentally prevents condenser fouling, guarantees normal heat exchange of the condenser, and saves cleaning costs.
Increase the concentration ratio of circulating water: Because the hardness of circulating water is very low, the concentration ratio of circulating water can be increased by more than 3 times and the discharge of wastewater can be reduced by 75%.
The amount of equipment investment is mainly determined by the circulation amount. Generally, the investment for each ton / hour circulation amount is 95-120 yuan.
