Spiral plate heat exchanger introduction

Spiral-plate heat exchanger is a kind of high-efficiency heat exchanger device which is applicable to vapor-vapor, vapor - liquid, liquid – liquid heat transfer to liquid. It is suitable for chemical, oil, solvents, pharmaceutical, food, light industry, textile, metallurgy, steel rolling, coking and other industries. It can be divided into non-detachable type (Ⅰ) and detachable type (Ⅱ, Ⅲ) spiral plate heat exchangers according to the structural form.

Structure and performance

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. 

Product advantages

After years of practice, spiral-plate heat exchanger is proved to be a high-efficient heat exchanging device which is applicable in chemistry, oil, solvent, medical, food, light industry, textile, metallurgy, steel rolling and coking industries, etc. By absorbing international modern and advanced technology and with unique and optimized design, the liquid-liquid, vapor-water heat exchanger is manufactured. The product structure process complies with standard of “`Aerfaladai” Company in Sweden. The end surface of spiral plate adopts hem arc welding. The special process of “Top distance pillar” is capacitor power storage contactor which improves inner and outer appearance and wins approval from “BaoGang”. It can replace imported product.

Non-detachable spiral plate heat exchanger is designed according to basic parameter and size stipulated in standard JB/TQ714-89 Form of non-detachable spiral plate heat exchanger by Ministry of Machinery Industry. It is of simple manufacturing, low cost, small size and good heat transfer performance, etc. It also has disadvantages, for example, machinery cleaning is not allowed and it is hard for inspection & repairing when broken down. The selection should be based on the actual situation of the project to select specific equipment to make it the most effective. to make it  the most effective.
