  What is a spiral plate heat exchanger? In simple terms, it is one of the common types of heat exchangers. It is a type of heat exchanger that is made of two spiral passages made of metal plates and exchanges heat between hot and cold fluids. Its advantages are compact structure, small size, and high heat transfer efficiency. Its application is mainly in industries that require heat conversion, such as petroleum, chemical, pharmaceutical, machinery, electric power, and environmental protection. 1. Specific types of spiral plate heat exchangers. Spiral plate heat exchangers are generally divided into two types: detachable and non-detachable. Among them, the non-detachable structure is relatively simple, that is, both ends of the spiral channel are all welded, so that it is not removable. The detachable spiral plate heat exchanger is different in structure from the non-detachable type, mainly in that the two ends of the spiral channel are sealed structures instead of welded. As for the

 Autumn and winter are the peak of heat exchanger selection every year. Before the peak of selection, the long-term heat exchanger must be repaired and removed. The heat exchanger is a kind of compact and high-efficiency heat transfer equipment. It is a kind of excellent heating, cooling, recycling and rapid sterilization equipment. But I don’t know that due to the long-term operation of the heat exchanger, the difference in the purity of the cooling or heating side, and the difference in the material characteristics of the processing technology, the fouling of the heat exchanger has long been unavoidable, resulting in the heat transfer The thermal efficiency is reduced, thereby endangering all normal production and processing and safety factors of machinery and equipment. Therefore, the heat exchanger should be removed on time to remove stains and ensure high efficiency heat transfer and normal production. One, the choice of heat exchanger cleaning method According to the different cl
