Spiral plate heat exchanger is a heat exchanger which is made of two flat metal plates with two spiral channels.There are two types of spiral plate heat exchanger: detachable and non-detachable.
Spiral plate heat exchanger has the advantages of small volume, compact equipment, high heat transfer efficiency, low metal consumption, suitable for dry liquid-liquid, gas-liquid, gas-liquid convection heat transfer, steam condensation and liquid evaporation heat transfer, chemical industry, petroleum, medicine, machinery, electric power, environmental protection, energy saving and heat conversion industries.
Cleaning spiral plate heat exchanger:
Different cleaning agents and processes should be selected according to different internal heat transfer media.
A, scale
Long-term operation will cause the equipment to be blocked by scale, which will reduce efficiency, increase energy consumption and shorten life.If the scale can not be removed in time, it will face the risk of equipment maintenance, shutdown or scrap.For a long time the traditional cleaning methods such as mechanical methods (scraping, brush), high-pressure water, chemical cleaning (pickling), etc.The residual acid causes secondary corrosion to the material or corrosion under the scale, leading to the replacement of the equipment. In addition, the waste cleaning liquid is toxic, requiring a large amount of money for wastewater treatment.Enterprises can use kd-l412 high-efficiency environmental cleaning agent produced by shandong kaidi chemical industry co., LTD., which has the characteristics of high efficiency, environmental protection, safety and non-corrosion, not only good cleaning effect but also no corrosion to the equipment, to ensure the long-term use of the equipment.
B. oil or tar
If the spiral plate heat exchanger medium contains light, heavy oil or tar substances, it will gradually form oil or coal tar in the inner wall during the long running process.If the grease can not be removed in time, it will face the risk of equipment maintenance, shutdown or scrap.Here, it is recommended to use professional coke cleaner spiral plate heat exchanger, it adopts contains special charged based on the strong penetrating agent and synergistic agent refined but become, for all kinds of mechanical equipment, pipelines, diesel generators, fuel generator set a special carbon deposition has excellent dissolving removal ability, no matter how much carbon deposition thickness or hardness, can be found within 4 to 6 hours of removal from the equipment surface.Very effective, very fast and very effective.It is suitable for the cleaning of oil scale, coal tar scale and carbon deposition in all kinds of pipeline, coal tar pipeline, spiral plate heat exchanger, reaction kettle, benzene washing tower, distillation tower and other equipment.
