The Hazards of scale - Boiler softened Water Equipment

1. Fuel waste - The thermal conductivity of scale in boiler softening water equipment is very poor. It is dozens of times or even lower than that of steel. The presence of scale will deteriorate the heat transfer condition of the boiler's heating surface, increase the flue gas temperature, and increase fuel consumption. According to experiments, if there is 1mm thick scale on the inner wall of the boiler, 3-5% more coal will be consumed. 2. Damaging the heating surface - Due to the poor thermal conductivity of scale in the boiler softening water equipment, and the fact that scale is prone to form on the metal heating surface with a high heat load. At this point, the temperature of the metal wall at the scaling area will be too high, causing a decrease in metal strength. Under the action of pressure, the overheated area will deform, bulge, and even lead to accidents such as explosions. At the same time, scale can also cause under-deposit corrosion of metals. Under the condition that there is scale adhering to the water-cooled wall tubes of the boiler

What are the reasons for the decline in water production capacity of water treatment equipment?

The main reasons for the decline in the water production capacity of water treatment equipment are as follows: 1. The reduction in the number of membrane modules. 2. The membrane modules should be compacted in accordance with the designed number of membrane modules. When operating under conditions far exceeding the reference pressure, the membrane module will become compacted. Replace the membrane module. 3. Operate under conditions of higher recovery rate. When operating under a recovery rate of over 75%, the volume of concentrated water decreases, which leads to an increase in the water concentration ratio within the membrane module. As a result, the quality of the feed water deteriorates significantly. Due to the increase in osmotic pressure of this feed water, the permeation volume decreases. In severe cases, salt scale will precipitate on the membrane surface. 4. During operation, the pressure difference of the reverse osmosis device rises according to the designed recovery rate of water production. Improve the operation and management of the pretreatment device, improve the reverse osmosis water quality, and use

The working principle and function of water softening equipment

The working principle of water softening equipment: The hardness of water is mainly composed of cations in it: calcium (Ca2+) and magnesium (Mg2+) ions. When the raw water with hardness passes through the resin layer of the exchanger, the calcium and magnesium ions in the water are adsorbed by the resin, while sodium ions are released. Thus, the water flowing out of the exchanger is softened water with the hardness ions removed. When the resin adsorbs calcium and magnesium ions to a certain saturation, the hardness of the effluent increases. At this point, the soft water equipment will automatically carry out the regeneration work of the exhausted resin according to the preset program. By passing a higher concentration of sodium chloride solution (brine) through the resin, the exhausted resin will be restored to the sodium type resin. The function of softened water produced by softened water equipment: Softened water reduces or avoids the formation of scale and is suitable for washing and bathing. In addition, it also avoids water in the pipes

The role of ultraviolet rays in domestic drinking water

I. Advantages of Ultraviolet Devices: 1. The problem of two parasites (Cryptosporidium and Giardia). Abroad, drinking water is generally used. The discovery of Cryptosporidium in water has become the main reason for the application of ultraviolet devices (ultraviolet light can kill cryptosporidium). Although drinking water habits have protected public health, improving the quality of water supply and providing direct drinking water will be a trend. Currently, the new water quality standards have included Cryptosporidium and Trichomonas. 2. The issue of by-products of ultraviolet devices. At present, all water sources are polluted to varying degrees. By-products are a relatively common problem and pose a significant threat to human health. For instance, trihalomethanes and haloacetic acids are carcinogens. Haloacetic acid may concentrate after boiling due to its relatively high boiling point. Ozone generates bromate. On January 4th of this year, the United States reported

: EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

: Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

: Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
