1. Hybrid heat exchanger
The main working principle of this type of heat exchanger is that the two media transfer heat to each other through contact to achieve heat transfer. The contact area directly affects the heat transfer. The medium of this type of heat exchanger is usually a gas and the other is a liquid. , It is mainly heat transfer equipment with cooling water tower equipment as the main body, but usually involves mass transfer, so it is difficult to distinguish the relationship with the tower device. It is usually classified as tower equipment, and the cooling water tower used in chemical plants and power plants is the most typical Hybrid heat exchanger.

　　 2. Energy storage heat exchanger (abbreviated as accumulator)

　　The principle of this kind of heat exchanger is that after the heating medium reaches a certain temperature by heating the solid substance, the cold medium is heated by the solid substance, and the heat and cold alternately make it reach the purpose of heat transfer. It is mainly used to recover and utilize the heat of high-temperature exhaust gas.
　　3, partition type heat exchanger

　　The principle of this type of heat exchanger is that the cold and hot two media are separated by a solid partition, and heat is exchanged through the partition. The amount of this type of heat exchanger is very large, accounting for 99% of the total. According to different structures, it can be divided into tube type, plate type and other types.

Method for cleaning vicarb heat exchanger plate

2020-02-06 17:25:09

Vicarb heat exchanger plates have been widely used in some areas such as central heating and chemical industry. The plate heat exchanger has a good heat exchange effect, but it is prone to produce scale and impurities, which will block the flow of the plate heat exchanger and reduce the heat exchange effect. So, how to clean the plate heat exchanger?Plate heat exchangers can be disassembled and recirculated.

Disassembly and cleaning steps:
Disassembly and cleaning can clean both processes of the heat exchanger. The main steps are:
1. Close the two water inlet and outlet valves of the heat exchanger;

2. Measure the distance between the baffles of the heat exchanger and make a record;

3. Disassemble the plate heat exchanger, empty the medium in the equipment, disassemble in the prescribed order, and make a record. Be careful not to damage the gasket and the plate during the disassembly process;

4. During the cleaning process, the plates should be cleaned piece by piece, and soaked and washed. In the case of high-pressure cleaning, the cleaning should be performed below the specified pressure;

5. After processing, put it back in the plate heat exchanger baffle in the original order, paying attention to distinguish the front and back. Control the strength when tightening the clamping bolts firmly, otherwise it is easy to crush the plate;

6. Open the outlet valve and inlet valve of the plate heat exchanger to see if there is any leakage. If there is no leakage, the cleaning is complete.

Cycle cleaning steps:
If it is used in the chemical industry, firstly close the inlet and outlet valves of the plate heat exchanger, and add the cleaning agent to the system through a tube pump or a water tank for internal circulation until the concentration of the cleaning agent no longer changes and the impurities in the equipment are discharged.

If it is a passivation treatment, it is necessary to ensure that after the chemical descaling is completed, no rust or other phenomena will occur in the pipeline. The amount of passivation cleaning solution needs to be determined according to the amount of water during cleaning, and the ph value cannot be too high, otherwise the effect will be poor, and it will be discharged after six hours.

Finally, the plate heat exchanger was restored, and the inlet and outlet water valves were opened, indicating that the cleaning was completed.
The role and advantages,disadvantages of plate heat exchangers

Plate heat exchangers are a type of mobile device that transfers heat between metal plates because the liquid is spread over more surfaces, which increases the exchange rate. Metal tubes are used to heat fluids.

The role of plate heat exchangers
The plate heat exchanger is based on different external and internal components, the welding plate exchange plates are welded together, and the brazed plate type construction model is vacuum brazed. In many cases, in order to make smaller sections work better, some chambers are designed to be thinner, allowing most of the liquid to contact the plate, improving heat transfer.

The plate heat exchanger can play a good heat transfer effect in the boiler heating in winter. In the daily use process, it is necessary to do a good job of protecting this equipment. The plate heat exchanger is a kind of equipment that can play multiple benefits and functions for us. The user clearly knows its role and protects it so that it can play a greater role.

Advantages of plate heat exchangers
High heat transfer coefficient. The plate heat exchanger has a small flow channel, the plates are wavy, and the cross-section changes are complex, which makes the flow direction and velocity of the fluid constantly change, which increases the disturbance of the fluid and has a high heat transfer coefficient.

Great adaptability. The required heat transfer area can be achieved by increasing or decreasing the plate. A heat exchanger can be divided into several units, which can be used for heating or cooling between several fluids at the same time.

Compact structure, small size and few consumables. The heat transfer area per cubic meter volume can reach 250m², and the heat transfer surface per square meter only needs about 15kg of metal.

Dirt factor is small. Due to the large flow disturbance, dirt is not easily deposited. The plate heat exchanger plate is of good material and has little corrosion, which makes its fouling coefficient value smaller. Plate heat exchangers mainly use metal plates, so the price of raw materials is cheaper than the same metal pipes.

Disadvantages of plate heat exchangers
1) Poor sealing and easy to leak. The gasket needs to be replaced frequently, which is troublesome.
2) The use pressure is limited, and generally does not exceed 1MPa.
3) The use temperature is limited by the temperature resistance of the gasket material.
