Spiral plate heat exchanger introduction
 Spiral plate heat exchanger is a highly efficient heat exchanger equipment, Applicable for vapor-vapor, vapor - liquid, liquid – liquid heat transfer to liquid. 

Application of spiral plate type heat exchanger
 Through years of practical use of proof, Spiral plate heat exchanger is indeed a highly efficient heat transfer equipment. It is suitable for chemical, petroleum, solvent, pharmaceutical, food, light industry, textile, metallurgy, steel rolling, coking and other industries.

Non-removable spiral plate heat exchanger features
 Non-removable spiral plate heat exchanger is according to the standard machine parts JB / TQ724-89 non-removable spiral plate heat exchanger in the form of the basic parameters and dimensions of the provisions of the design, It has the advantages of simple manufacturing, low cost, small size and good heat transfer performance, But it also has its shortcomings, for example, can not be mechanical cleaning, broken and difficult to overhaul, etc., The user should select the specific equipment according to the actual situation of the project to make it the most effective.

Structure and performance of Spiral plate heat exchanger
 1, This equipment is suitable for liquid - liquid, gas-gas, gas - liquid convection heat transfer which can be used for vapor condensation and liquid evaporation heat transfer. Therefore it is applicable in chemical industry, petroleum, medicine, machinery, electric power, light industry and textile industries, etc.
 2, This equipment is composed of two pieces of steel plates to form two uniform spiral channels. Two heat transfer cut-off ways may realize fully reversed flow ,which is applicable for heat transfer with small temperature differential. Therefore it is easy for low temperature heat source recycling and accurate outlet temperature control. 
 3,The connection pipe on the shell is of tangential structure with small partial resistance. The curvature of spiral channel is even and the fluid has no large direction change inside the equipment. Therefore the total resistance is small, which may increase design flow speed and realize higher heat transfer ability.
 4. The end surface of spiral channel is sealed because of welding so the sealing performance is good with reliable structure.
 5. It is not easy for inspection and repairing especially when problems occur on inner plate. Some factories will cut off the weld joints at two ends of the equipment and spread the plate for welding repairing before rolling. However, this may take a lot of time. Therefore corrosion proof is important when using spiral plate heat exchanger.
 6. Mechanical cleaning is not allowed because it is proved by production practice that compared with general tube type heat exchanger, it is not easy to be blocked, in particular , that impurity of suspended particle such as silt , small shell and the like are not easy to deposit in the spiral channel. The reasons are: 1. these impurities are settled down in single-direction channel and the impurities will be flushed away once rotating flow is formed. 2. There’s no dead corner inside the spiral channel so the impurities are easy to be flushed away.
 7. There are spacing columns inside the spiral channel to support distance in the channel so fiber shaped impurities (cotton yarn, grass stick and leaves, etc.) are not allowed to enter inner part of the heat exchanger.
 8. Temperature of cooling water outlet shall be strictly controlled below the scaling temperature.
 9. The commonly used cleaning method is steam blowing off or alkaline cleaning. Steam blowing is to blow the impurities out of the equipment, which is a effective method believed by many factories.
