Plate heat exchangers are equipment for many occupations. Following the rapid development of heat exchange occupations, plate heat exchanger equipment has also been improved and innovated from time to time. Now, high-efficiency, energy-saving, and environmental protection have become mainstream flows in shopping malls. Breaking the market to become the urgent task of the plate heat exchanger career development, but in the future, what kind of expansion shape will China's heat exchange equipment market present?

In recent years, with the rapid development of China's petrochemical and iron and steel industries, the demand for heat exchangers has fallen sharply, but the supply capacity of world enterprises is unlimited, causing the heat exchanger profession to take the shape of an oversupply mall, and a huge supply gap needs to be exported. To compensate. In the future, some enterprises in the heat transfer profession will only focus on the immediate results, and use various unreasonable competition wrists to fight price wars, which seriously hinders the normal development of the profession.

At present, the plate heat exchanger equipment in world malls is made in China. Although it has been developed very quickly, there are still some achievements and difficulties. In the future, the needs of world shopping malls will present the following characteristics: higher requirements for product quality, such as environmental protection and energy-saving products will be the main points of the future, requiring the product to be more cost-effective; the characteristics of products, diversified demand trends Vigorous, and gradually pay attention to the choice of brand products.

Facing the increasingly fierce occupation of plate heat exchangers, increasing market demand from time to time, in order to better adapt to the expansion of the market, it should absorb advanced foreign technology, advance independent and independent talents, ensure product quality and functions in an all-round way, and make the product life cycle Continue to extend, and then expand the scale of business malls ineffectively, and improve economic efficiency, but this expansion should be under the conditions of ensuring product quality.

板式冷却器 好的一种换热设备,在中止换热时必需求有液体在管束内。 We all know that the plate cooler is a kind of heat exchange equipment that works well with plate coolers . When the heat exchange is stopped, liquid must be in the tube bundle. In general, we call it cooling water. The selection of cooling water is also a very important process. It has also been done in more detail.

The function of the plate cooler circulating water system is to send cooling water (sea water) to the upper and lower pressure condensers to cool the high-pressure cylinder of the steam turbine, so as to maintain the vacuum of the upper and lower pressure condensers, so that the steam and water circulation can be continuous. In addition, it supplies water to open water systems and ash flushing systems.

1.Even though soft water or treated industrial circulating water should be used, it is important to prevent scaling and avoid affecting heat exchange results. Calcium ions are controlled at 50-80mg / L magnesium ions are controlled at 40-80mg / L bicarbonate ions. Content of chloride ion in 100-150mg / L circulating water.

2. Chloride stress degenerates on stainless steel during idle breeding. If the content is too high, pitting will occur on the plate, causing the content of chloride ions in the circulating water with oil and water turbidity (when the water temperature is 60 ° C): less than 50mg / L. 304L less than 300mg / l plate material can choose 316L.

3, stainless steel 304, 316L applicable scope Water, river water, oil and other general inorganic and inorganic media. 304 plate cooler can be used for various concentrations of carbonic acid, ammonia, and alcohol ≤100 ℃. It has poor resistance to decay in sulfuric acid and hydrochloric acid. It is especially sensitive to the degradation caused by chlorine-containing media. 316L has better resistance to decay.

Therefore, we still have to think about the above points when buying products. We want to avoid some bad conditions. I hope you can read the above contents carefully.
