These are the advantages of all-welded plate heat exchanger. I believe you also have a deeper understanding of the all-welded plate heat exchanger. If you have any questions, you can pay attention to us directly. You can also leave us a message directly.
All welded plate heat exchangers, all plates and bundles are made of special stainless steel materials, made by argon arc welding, not sealed with non-metallic materials, with high temperature resistance, pressure resistance and corrosion resistance. It is applicable to most heat exchange processes that are not applicable to general plate heat exchangers. It is a heat exchange equipment that combines the advantages of removable heat exchangers and shell heat exchangers.
The heat exchange plate is pressed by a special mold, and its surface is smooth and not easy to dirt. Its special ripple design can cause turbulence even at a low flow rate of the fluid. It has high thermoelectric efficiency, compact structure and convenient use. It is widely used in petroleum, chemical, iron and steel plants, power stations, metallurgy and other industrial fields.
Seen from the appearance, the separated plate heat exchanger can be removed directly. Generally, the four inlet and outlet positions are on the same side frame plate. The four sides of the whole welded plate heat exchanger are up, down, left and left. The frame itself has no holes.
Characteristics of all-welded plate heat exchanger:
1. Heat transfer efficiency
The board structure adopts a special corrugated structure shape and spacing, and the fluid flow form is complex, which will produce strong turbulence at low flow rate. To a certain extent, the heat transfer ability will be brought into play to obtain high heat transfer performance. The total heat transfer coefficient is 3-5 times that of shell heat exchanger. Under the same heat transfer conditions, the heat transfer area is only 1/3-1/4 of the shell shape. In addition, the dust coefficient of the all-welded plate heat exchanger is only one fifth of that of the heat pipe heat exchanger, which has good heat exchange performance.
2. Wide application range
Its special all-welding process does not require sealing non-metallic materials, and its structural design is diverse, which can be applied under high temperature and pressure.
3. Low pressure loss
A special plate wave structure makes the fluid fill the flow channel formed between the plates. All the plate surfaces participate in the heat exchange. The media can realize the flow without dead zone in the flow channel, reducing the kinetic energy consumption to a certain extent and reducing the operating costs.
4. Compact structure and small floor area
The whole welded plate heat exchanger has a compact structure and a wide range of space conditions. The heat exchange area per unit area is 2-5 times that of the tube shell, and there is no need to extract the maintenance space of the tube bundle. When performing the same heat exchange operation, the floor area of the whole welded plate heat exchanger is about 1/6-1/10 of the shell heat exchanger, which can greatly reduce the investment cost of infrastructure.
5. Scaling is not easy
During the working process of welding around the heat exchange plate, due to the influence and limitation of thermal stress, the plate can be stretched freely, so the plate surface is not easy to be dirty.
These are the advantages of all-welded plate heat exchanger. I believe you also have a deeper understanding of the all-welded plate heat exchanger. If you have any questions, you can pay attention to us directly. You can also leave us a message directly.
