Why can't industrial thermal heat exchanger be blocked according to the shape of the heat transfer surface

2021-03-04 17:18:40


Industrial thermal heat exchangers are classified according to the shape and structure of the heat transfer surface.

(1) Tubular industrial thermal heat exchanger: Tubular industrial thermal heat exchanger conducts heat transfer through the wall of the tube. According to the structure of the heat transfer tube, it can be divided into tube-type heat exchange tube, sleeve-type industrial thermal heat exchanger, and snake tube. There are several types of industrial thermal heat exchangers and fin-tube industrial thermal heat exchangers. Tubular industrial thermal heat exchangers are the most widely used.

(2) Plate type industrial thermal heat exchanger: Plate type industrial thermal heat exchanger conducts heat transfer through the plate surface. According to the structure of the heat transfer plate, it can be divided into flat plate type industrial thermal heat exchanger, spiral plate type industrial thermal heat exchanger, plate fin type industrial Thermal heat exchanger and thermal plate industrial thermal heat exchanger.

(3) Special form of industrial thermal heat exchanger: This type of industrial thermal heat exchanger refers to an industrial thermal heat exchanger with a special structure designed according to the special requirements of the process, such as rotary industrial thermal heat exchanger, industrial thermal heat exchanger heat pipe Type industrial thermal heat exchanger, etc.

An industrial thermal heat exchanger is a device that transfers part of the heat of the hot fluid to the cold fluid, that is, a large airtight container is filled with water or other media, and there are pipes passing through the container to let hot water from the industrial thermal heat exchanger pipe Flow through.

Due to the temperature difference between the hot water in the pipeline and the cold and hot water in the container, heat exchange will be formed, that is, the heat balance of junior high school physics. The heat of high-temperature objects is always transferred to low-temperature objects, so the industrial thermal heat exchanger pipes The heat exchange in the water is given to the cold water in the container. The industrial thermal heat exchanger is also called the heat exchanger.

The water quality in each region is different, and the actual requirements of each industrial thermal heat exchanger project are different. Therefore, the industrial thermal heat exchanger design unit should select the specific equipment material industrial thermal heat exchanger manufacturer according to the actual situation, especially if the water quality is serious. Corrosion, the industrial thermal heat exchanger must use 316 stainless steel. The design unit and the user shall explain and request this. The manufacturer of the industrial thermal heat exchanger can customize according to the requirements. If the heat exchanger is damaged due to corrosion, please do not blame the industrial thermal heat exchanger. The supplier assumes full responsibility.

　　 Due to the layout characteristics of the industrial thermal heat exchanger, the industrial thermal heat exchanger has a self-cleaning function, so it should not be clogged. After clogging, it will affect its self-cleaning function. Any industrial thermal heat exchanger is not easy to be clogged.

Especially the plate type industrial thermal heat exchanger (including the spiral plate), once it is blocked, it will seriously affect the heat transfer effect, and cleaning is appropriate and difficult, and the entire industrial thermal heat exchanger can be scrapped, and the blockage of the tube type industrial thermal heat exchanger will also seriously affect the heat transfer. , But tube cleaning is very convenient.

  • 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

    2020-01-27 17:14:32
    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.
