Spiral plate heat exchanger

Specializing in the production of tower internals at Kelong Chemical Packing Tower Factory in Pingxiang City, Jiangxi Provincestainless steelSpiral plate heat exchanger，This heat exchangerThrough years of practical use, it has been proven that,It is an efficient heat exchanger equipment suitable for steam-Steam, steam-Liquid, liquid-Liquid, heat transfer to liquid, commonly used inIn industries such as chemistry, petroleum, solvents, pharmaceuticals, food, light industry, textiles, metallurgy, steel rolling, coking, etc.
Non detachablespiral plateformulaThe heat exchanger is designed according to the standards of the mechanical industryJB/TQ724-89Carry out manufacturingDesigned based on the specifications of basic parameters and dimensions, it has the advantages of simple manufacturing, low cost, small size, and good heat transfer performance. However, it also has its shortcomings, such as inability to perform mechanical cleaning and difficulty in maintenance when damaged,customerSpecific equipment should be selected based on the actual situation of the project to make it effective.

The Cologne Chemical Packing Tower Internal Factory in Pingxiang City, Jiangxi Province can producenoDetachable type（ISpiral plateformulaheat exchangerandDetachable spiral plateformulaheat exchangerThe specific introduction is as follows.

1Non detachable（ISpiral plateformulaStructure and performance of heat exchangerIntroduction as follows：
1This device is suitable for: liquid-Liquid, gas-Qi, Qi-Liquid convection heat transfer can be used for steam condensation and liquid evaporation heat transfer, and can be selected for industrial sectors such as chemical, petroleum, pharmaceutical, machinery, power, light industry, and textile.
2This equipment is made up of two steel plates rolled together, forming two uniform onesspiralChannel, two types of heat transfer cut-off can achieve full countercurrent flow, suitable for small temperature difference heat transfer, easy to recover low-temperature heat source and accurately control outlet temperature.
3The connecting pipe on the shell is a tangential structure with low local resistance. The curvature of the spiral channel is uniform, and there is no significant reversal of fluid flow inside the equipment, resulting in low overall resistance. Therefore, the design flow rate can be increased to have higher heat transfer capacity.
4The end face of the spiral channel is welded and sealed, with good sealing performance and reliable structure.
5It is not easy to maintain, especially when there are problems with the internal panels, which are extremely difficult to repair. Some factories remove all the welds on both ends of the equipment, flatten and weld the panels again, and then roll them up. This consumes too much time, so it is very important to use spiral plate heat exchangers for corrosion prevention.
6Mechanical cleaning cannot be carried out, production practice has proven that spiral platesformulaCompared with general tubular heat exchangers, heat exchangers are less prone to clogging, especially suspended particles such as sediment and small shells that are less likely to deposit in spiral channels. Analyze the reasons for this; One reason is that it is the deposition of single channel impurities in the channel, and once a circulating flow is formed, it will increase to the point where it will be washed away. The other reason is that there are no blind spots in the spiral channel, and impurities are easily washed out.
7Because there are fixed distance columns supporting the spacing between the spiral channels, no fibrous impurities (such as cotton yarn, grass sticks, leaves, etc.) are allowed to enter the interior of the heat exchanger.
8Strictly control the outlet temperature of the cooling water below the scaling temperature.
9The commonly used cleaning method is steam blowing or alkali washing. Steam blowing should be directed towards the connecting pipe to blow out impurities from the equipment. Many manufacturers consider this to be an effective method.

IIDetachable type（ⅡTypeⅢStructure and performance of spiral plate heat exchanger:
The structural principle is basically the same as that of a non detachable heat exchanger, but the channels can be disassembled for cleaning and sealed with heads at both ends. Especially suitable for liquid to liquid exchange with viscous and precipitated liquids, as well as gas-liquid and vapor condensation. Due to the need to add components such as heads and flanges to detachable heat exchangers, the equipment cost is slightly higher than that of non detachable heat exchangers.
