Stainless steel plate heat exchanger clean
The stainless steel plate heat exchanger is a compact and efficient heat exchange equipment, but its heat exchange temperature is high, the internal flow aperture is small, and it is easy to scale, which causes the heat exchange efficiency of the stainless steel plate heat exchanger to decrease, thus affecting the normal production. It is safe to carry out and equipment, so it needs to be descaled by chemical cleaning.
The scale of the stainless steel plate heat exchanger is mainly water scale, relatively hard, and firmly combine with the heat transfer plate, and it is difficult to remove it by physical means, so the acid cleaning method in chemical cleaning is selected to remove the scale. According to the scaling situation, aging degree and user requirements of stainless steel plate heat exchangers, the chemical cleaning of stainless steel plate heat exchangers can be divided into two methods: disassembly cleaning and non-disassembly cleaning. Disassembly cleaning, descaling is relatively thorough, the effect is good, but the labor is large, the process is complicated, and it is easy to cause adverse effects such as leakage of heat exchanger and damage of spare parts; no demolition cleaning is not thorough enough, but the labor is small and the process is simple. It is not easy to cause adverse effects such as leakage of heat exchangers and damage to spare parts. When the plate heat exchanger is severely fouled, the heat exchange efficiency is low, or even blocked, it must be disassembled and cleaned; when the plate heat exchanger is less fouled or aged, it can be taken without disassembly cleaning.
