Double-tubesheet heat exchanger is a kind of high efficiency heat exchange equipment with unique structure and exquisite design, which is widely used in industry, construction and electric power fields. The following is a detailed introduction to the double tubeplate heat exchanger:

 

 

Double tubeplate heat exchanger adopts double tubeplate structure design, which makes the tube and shell process respectively use their own tubeplate connection. Specifically, it consists of two parallel and sealed plates that form two pipes between them. One pipe (inner pipe) is used to flow the working fluid, and the other pipe (outer pipe) is used to flow the cooling fluid. The gap between the two plates is the heat transfer zone, where heat is transferred by heat transfer through the tube wall.

 

 

It is the use of two kinds of fluid flow in the tube bundle heat exchange to achieve heat transfer. When the working fluid flows in the inner pipe and the cooling fluid flows in the outer pipe, due to the temperature difference between the two, heat will be transferred from the higher temperature fluid to the lower temperature fluid, thus achieving the exchange of heat. This heat transfer process follows the law of heat conduction, that is, heat is always transferred from a hot object to a cold object.

 

 

1. High efficiency heat exchange : double tube plate heat exchanger adopts double tube plate structure, which increases the heat exchange area and improves the heat exchange efficiency, and can meet the heat demand under various working conditions.

2. Corrosion resistance : Usually made of corrosion resistant materials such as stainless steel or titanium, which can cope with the heat exchange needs of various corrosive media and extend the service life of the equipment.

3. Easy maintenance : Although the tube bundle can not be extracted and cleaned, because of its compact structure, easy to disassemble and clean, it is relatively simple to maintain and not easy to have equipment failure.

4. Compact structure : small footprint, easy to install and layout, suitable for limited space occasions.

 

 

Double tube plate heat exchanger is widely used in industry, construction and power and other fields. In the chemical, pharmaceutical, petroleum and fertilizer industries, it is used to achieve large amounts of heat transfer and control; In HVAC systems, it is used to recover waste heat and reuse it to improve energy efficiency. In power plants, it can recover waste heat from the exhaust gas and be used to preheat the water supply to the boiler, improving the efficiency of the boiler.

 

 

1.Design and installation : The design and installation of the double-tube plate heat exchanger needs to take into account the internal channel structure, tightness and other factors to ensure the safety and reliability of the equipment. Therefore, it is recommended that installation and maintenance be carried out by a professional design and construction team.

2.Applicable medium : Due to the internal structure of the double-tube plate heat exchanger, its applicable medium is subject to certain limitations compared with other heat exchange equipment. When selecting the equipment, it is necessary to comprehensively consider the actual working conditions and media characteristics.

3.Regular maintenance: In order to maintain the good performance of the equipment and extend the service life, it is recommended to regularly maintain and check the double-tubesheet heat exchanger. Including cleaning pipes, checking sealing performance, etc.

In short, the double-tube plate heat exchanger is a kind of heat exchange equipment with high efficiency, corrosion resistance and easy maintenance, and has a wide application prospect. In practical applications, appropriate equipment models and specifications need to be selected according to specific needs and conditions to ensure that they can play the best performance and benefits.
