High Pressure Plate Heat Exchanger
Custom Made High Using Pressure Vessel Grade Shell And Ss304 Ss316l Sanitary Double Tube Sheet Heat Exchanger
The plate heat exchanger is a high-efficiency heat exchanger made up of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, long service life and so on. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, the floor space is one-third of the tube heat exchanger, and the heat recovery rate can be as high as 90% or more.
There are mainly two types of plate heat exchangers: frame type (removable) and brazed type. The plate forms mainly include three types of herringbone corrugated plates, horizontal straight corrugated plates and knob-shaped plates.
The detachable plate heat exchanger is made of many stamped corrugated thin plates at a certain interval, sealed with gaskets around them, and laminated and compressed by a frame and a compression screw. The four corner holes of the plates and gaskets form a fluid divider. The piping and the collection pipe, while reasonably separating the cold and hot fluids, make them flow in the flow channels on both sides of each plate, and heat exchange through the plates
The optimization design calculation of the plate heat exchanger is to reasonably determine its model, process and heat transfer area under the condition of the known temperature difference ratio NTUE, so that NTUp is equal to NTUE.

(Comparison between plate heat exchanger and shell-and-tube heat exchanger)
a. High heat transfer coefficient;
Since different corrugated plates are inverted each other to form a complex flow channel, the fluid flows in a three-dimensional rotating flow in the flow channel between the corrugated plates, and can generate turbulent flow at a low Reynolds number (generally Re=50~200), so heat transfer The coefficient is high, generally considered to be 3 to 5 times that of the shell-and-tube type.
b. The logarithmic average temperature difference is large, and the terminal temperature difference is small.
In the shell-and-tube heat exchanger, the two fluids flow in the tube side and the shell side respectively, and the flow is generally cross-flow, and the logarithmic average temperature difference correction coefficient is small, while the plate heat exchanger mostly adopts co-current or counter-current flow. , The correction coefficient is usually about 0.95. In addition, the flow of cold and hot fluids in the plate heat exchanger is parallel to the heat exchange surface without bypass flow, so the temperature difference at the end of the plate heat exchanger is small, and the water heat can be exchanged. Lower than 1℃, while the shell-and-tube heat exchanger is generally 5℃fff.
c. Small footprint.
The plate heat exchanger has a compact structure. The heat exchange area per unit volume is 2 to 5 times that of the shell-and-tube type. Unlike the shell-and-tube type, there is no need to reserve a place for the maintenance of the tube bundle. Therefore, the same heat exchange can be achieved. The area of the heat exchanger is about 1/5~1/8 of the shell-and-tube heat exchanger.
d. Easy to change the heat exchange area or process combination;
As long as you increase or decrease a few plates, you can increase or decrease the heat exchange area; change the plate arrangement or replace a few plates to achieve the required process combination and adapt to new heat exchange conditions. The heat transfer area of the shell heat exchanger is almost impossible to increase.
e. Light weight;
The plate thickness of the plate heat exchanger is only 0.4~0.8mm, while the thickness of the heat exchange tube of the shell-and-tube heat exchanger is 2.0~2.5mm. The shell-and-tube shell is much heavier than the frame of the plate heat exchanger , The plate heat exchanger is generally only about 1/5 of the weight of the shell-and-tube type. 
f. The price is low;
Using the same material, under the same heat exchange area, the price of the plate heat exchanger is about 40%~60% lower than that of the shell-and-tube type.
g. Easy to make;
The heat transfer plate of the plate heat exchanger is processed by stamping, which has a high degree of standardization and can be mass-produced. The shell-and-tube heat exchanger is generally made by hand.
h. Easy to clean;
The frame type plate heat exchanger only needs to loosen the compression bolts to loosen the plate bundle and remove the plates for mechanical cleaning. This is very convenient for the heat exchange process that requires frequent cleaning of the equipment.
i. Small heat loss;
Only the shell plate of the heat transfer plate of the plate heat exchanger is exposed to the atmosphere, so the heat dissipation loss can be neglected, and no heat preservation measures are required. The shell-and-tube heat exchanger has a large heat loss and requires a thermal insulation layer.
j. Smaller capacity;
It is about 10%-20% of the shell-and-tube heat exchanger.
k. The pressure loss per unit length is large;
Due to the small gap between the heat transfer surfaces and the unevenness on the heat transfer surface, the pressure loss is greater than that of the traditional smooth tube.
l. Not easy to scale;
Due to the full turbulence inside, it is not easy to scale, and its scale coefficient is only 1/3~1/10 of the shell-and-tube heat exchanger.
m. The working pressure should not be too high, and leakage may occur;
The plate heat exchanger is sealed with a gasket. The working pressure should generally not exceed 2.5MPa, and the temperature of the medium should be below 250°C, otherwise it may leak.
n. Easy to block;
Since the passage between the plates is very narrow, generally only 2~5mm, when the heat exchange medium contains larger particles or fibrous substances, it is easy to block the passage between the plates.
The unique structure of double tubesheet heat exchanger makes the two media inside and outside the heat exchanger tube always keep isolated, immiscible, immiscible and free of cross contamination of materials.
1. High efficiency and energy saving: Its heat transfer coefficient is 3000～4500kcal/m2·°C·h, which is 3~5 times higher than the heat efficiency of shell-and-tube heat exchangers.
2. Compact structure: The plates of the plate heat exchanger are closely arranged. Compared with other types of heat exchangers, the plate heat exchanger occupies less area and space. The plate heat exchanger with the same area of heat exchange is only tube 1/5 of the shell heat exchanger.
3. Easy to clean and easy to disassemble: The plate heat exchanger is clamped by clamping bolts, so it is easy to disassemble and can be opened for cleaning at any time. At the same time, because the plate surface is smooth and clean, the turbulence is high and it is not easy to scale.
4. Long service life: The plate heat exchanger is made of stainless steel or titanium alloy plates, which is resistant to various corrosive media. The rubber pads can be replaced at will, and it is convenient to disassemble and repair.
5. Strong adaptability: The plates of the plate heat exchanger are independent components, and the process can be increased or decreased at will according to the requirements, with various forms; it can be applied to various different and technological requirements.
6. No liquid leakage, the plate heat exchanger seal groove is equipped with a liquid drain channel, and various media will not collude, that is,
