1. Water treatment equipment outside the boiler:
1. Chemical treatment:
After the water is taken out from rivers, lakes or underground layers, it is often mixed with impurities such as sediment, suspended matter, impurities, grease, etc. It is often necessary to add flocculants, coagulants or disinfectants to remove it first to achieve water purification. purpose.
2. Physical treatment:
1. Quartz sand filtration treatment:
It can effectively remove sand, gravel, sludge, and suspended solids in the raw water and has a water purification effect.
2. Activated carbon filtration treatment:
It can effectively remove organic matter, odor and residual chlorine in raw water.
3. Filtration treatment for removing iron and manganese sand:
It can effectively remove iron ions, silt, and impurities in the raw water. If the content of iron ions in the raw water is too high, an aeration tower must be installed in the front section.
3. Softening treatment:
The raw water needs to be softened before entering the boiler. The ion exchange resin can effectively remove calcium, magnesium, and other hardness in the water. It is necessary to provide good softening as boiler water, which can reduce the amount of treatment agent and keep the furnace clean.
4. Demineralization treatment:
It means that after raw water is treated with anion and cation exchange resin or R, O reverse osmosis, most of the soluble mineral salts in the water are removed. The water quality is extremely pure, but the equipment cost is expensive and the operation cost is high.
5. Treatment in the furnace:
In-furnace treatment refers to the addition of chemical treatment agents to improve the harm caused by impurities in the raw water to the boiler, and to ensure the normal, safe and economic operation of the boiler.
Boiler water purification equipment
Reverse osmosis is currently the finest filtration system. The reverse osmosis membrane can block all dissolved inorganic molecules and any organic matter with a relative molecular mass greater than 100. Water molecules can freely pass through the membrane to become a purified product. The desalination rate of dissolved salt is 95%, even up to 99%. The TFC composite membrane is composed of three layers: the first layer is a desalination layer, made of aromatic polyamide, with a thickness of 0.2цm (2000A); the second layer is a microporous polysulfone with a pore of about 150A and a thickness of about 40цm; The layer is a polyester support net with a thickness of about 120цm. The application of reverse osmosis is quite extensive, including the desalination of seawater and brackish water for drinking, waste water reuse, food and beverage processing, separation procedures in biomedicine, household drinking water and Purification of industrial water. At the same time, reverse osmosis is often used in the manufacture of ultra-pure water in the semiconductor industry, power industry (boiler water supply), and medicine/laboratory. Using reverse osmosis before ion exchange can greatly reduce the operating cost and regeneration frequency of the ion exchange system.
