The detachable plate heat exchanger is mainly composed of heat transfer plates, sealing gaskets, two end pressure plates, clamping bolts, brackets, flanges or bushings, and feet. The functions of each component are as follows:
1、 Heat transfer plate
The heat transfer plate is the main element of the heat exchanger, and the corrugation is generally made into a zigzag shape (of course, some manufacturers have their own version after research). According to the different fluid media, the material of the heat transfer plate is also different, and most of them are stainless steel304/316LMade of titanium material. Usually, molds are used to press plates into various groove or corrugated shapes, which can increase the stiffness of the plates, prevent deformation when they are under pressure, and enhance the turbulence of the fluid, thereby improving the heat transfer effect
2、 Sealing gasket
The sealing gasket of plate heat exchanger mainly plays a sealing role between the heat exchange plates. The materials include nitrile rubber, EPDM rubber, fluororubber, etc. Different rubbers are used according to different media. The rubber pad is elastic, which is conducive to sealing and easy to disassemble! Each rubber pad is designed and processed according to the shape of each heat exchange plate, with excellent sealing performance!
3、 Two end pressure plate
The two end pressure plate is mainly used to clamp and press all the heat transfer plates to ensure that the fluid medium does not leak. The production process of carbon steel plate is to buy back the steel plate and use a cutting machine to cut it to a certain size,Then enterPolishing, shaping, sandblasting treatment, sandblasting to improve rust prevention and paint adhesion, and then painting treatment.
4、 Clamping bolt
The clamping bolt mainly serves to tighten the pressure plates at both ends. Clamping bolts are generally double threaded, and when pre tightening the bolts, the torque of the fixed plate is evenly distributed. Step up the processing of bolts: According to the use of the heat exchanger, round steel with corresponding hardness, strength, and elongation requirements can be used after machine threading and galvanizing, and corresponding stainless steel bolts can also be matched!
5、 Hanging rack
The main purpose is to support the heat exchange plates for easy disassembly, cleaning, assembly, etc. The hanging bracket is mainly divided into two types: circular or square. The circular bracket is mainly composed of round steel wrapped in stainless steel or directly made of stainless steel rods. The square bracket is mainly made of channel steel as the main grooveSteel.
6、 Flanges or bushings
Mainly used for the docking of pipelines and heat exchangers, flanges are divided into10KGreach16KGGrade, national standards include the Ministry of Machinery, Ministry of Chemical Industry, etc., or non-standard flanges. The flange holes are determined by the size of the flange, with multiple materials and working conditions. Common lining materials include304 、316LStainless steel linerEPDMLiningNBRbush.
7、 Foot foundation
It is mainly used for fixing the heat exchanger during operation. Generally speaking, we have three or four feet (three with rear guide columns and four without rear guide columns), which come in the form of galvanized triangular iron feet with screws and carbon steel feet, all of which are used for fixing to the ground.
8、 GuidepoleAnd the pillar
Each heat exchanger has upper and lower guidespoleConvenient for the positioning and support of the board, the length is determined based on the number of boards, usuallycompareLonger, convenient for adding or removing plates in the later stage, generally made of carbon steel or stainless steel. The column is used to support the guide column and the rear end of the heat exchanger, and the material is also carbon steel or stainless steel.

Working principle
A detachable plate heat exchanger is composed of many stamped corrugated thin plates at certain intervals, sealed by gaskets on all sides, and overlapped and compressed by a frame and a clamping screw. The four corner holes of the plates and gaskets form the distribution and collection pipes for the fluid, while reasonably separating the hot and cold fluids, allowing them to flow in the flow channels on both sides of each plate and exchange heat through the plates.
characteristic
Detachable plate heat exchanger is a new type of energy-saving heat exchange device, which has high heat transfer efficiency, compact structure, and small footprint Easy to operate, convenient for cleaning, disassembly, and maintenance, and easy to change the heat exchange area or process combination.
