Description
Technical Field

When the steam condenser is used for a condenser or a heating network heater, steam is naturally condensed in a shell through heat release and is converted into condensate, the condensate is high in temperature and low in pressure, a steam trap and a condensate chamber are additionally arranged to normally work, the steam condenser is not easy to recycle, a special condensate pump and a condensate chamber are needed to normally work, the investment of matched equipment is large, and the installation is extremely inconvenient; the heat exchange coefficient (K value) is very low, and the steam-water heat exchange heat transfer coefficient (K value) is 2000-3000W/(m 2. K); in addition, cold source quality of water is generally relatively poor, flows in the pipe, causes heat exchange tube scale formation easily, causes heat exchange tube to block easily after long-time work, and resistance increases, causes circulating pump power to increase, and waste electric power to, heat exchange coefficient greatly reduced has wasted the energy, has increaseed coal consumption and electricity consumption, when scale formation is serious, even makes equipment damage, causes the pressure of pipeline to rise, causes danger such as tube explosion, and life is short, generally 4-6 years, cost of maintenance is high, and maintenance, washing are extremely inconvenient.
The existing plate heat exchanger is characterized in that a plurality of stainless steel plates punched through a die are combined, and are connected through bolts or welding. Independent channels are formed on the left side and the right side of each plate, and then a heat exchanger is formed through sealing gaskets, connecting ports and the like. Because the plate is stamped by the die, the plate is stretched and thinned, and local pitting corrosion is easy to occur; meanwhile, the flow passage between the plates is narrow, the requirements on the purification degree of the running medium are extremely high, and the blockage is easy to cause; because the flow channel is narrow, the flow velocity between the plates is high (2.5-4.5 m/s), so that the resistance of the equipment is high, abrasion and scouring are easy to cause, and the service life of the equipment is short. Although the liquid-liquid heat exchange coefficient is high (2000-4000W/(m 2. K)), the heat exchanger cannot be basically used in vapor-liquid heat exchange. In addition, due to the influence of the structural form, the maintenance and the cleaning are very inconvenient, and the workload of single maintenance and cleaning is very high; the stress of mechanical processing cannot be released in the stamping process, so that equipment is frequently subjected to stress corrosion, the plate cannot be maintained and can only be scrapped at one time, the service life is short (generally 3-5 years), a large amount of energy is wasted, and the national policies of energy conservation and emission reduction are not met.
