The liquid material of the granular powder to the suspended

1. 2. Long service life: The plate heat exchanger is made of stainless steel or titanium alloy plates, which is resistant to various corrosive media.. Advantages of plate heat exchanger 1.  

3. Even if there is a leakage, the medium will always be discharged. 2. Structural principle The detachable plate heat exchanger is made of many stamped corrugated thin plates at a certain interval, sealed by gaskets around them, and laminated and compressed by a frame and a compression screw. ​​No liquid leakage, the plate heat exchanger seal groove is equipped with a liquid drain channel, and various media will not collude. Such as cooling the internal circulation of generator sets and rectifiers; used for mechanical lubricating oil in metallurgical mines; sterilization and disinfection of hydraulic stations,

egg liquid, edible oil, and sterilization of beer and wine; used for Brazed Plate Heat Exchangers FHC014 waste heat recovery in the textile industry and paper industry; 3. Collect condensed water and centrally supply heat;    4. The liquid material of the granular powder to the suspended liquid containing a small amount of fiber can be processed by a plate heat exchanger. It can be used for heating, cooling, evaporation, condensation, sterilization, heat recovery and other occasions. The four corner holes of the plates and gaskets are formed Distributing pipes and collecting pipes for fluids,

while reasonably separating cold and hot fluids, make them flow in the flow channels on both sides of each plate and exchange heat through the plates. High efficiency and energy saving: Its heat transfer coefficient is 3000~4500kcal/m2·degreeC·h, which is 3~5 times higher than the heat efficiency of the shell and tube heat exchanger. The rubber pads can be replaced at will, and it is convenient to disassemble and repair. So what are the advantages of plate heat exchangers? The plate heat exchanger is here to answer everyone.

The plate heat exchanger for refrigeration

When the refrigerant evaporates in the refrigerating plate heat exchanger, it is easy to achieve complete evaporation to the level of no liquid. Compared with the shell-side tube heat exchanger for refrigeration, in addition to the general characteristics of the plate heat exchanger, the plate heat exchanger for refrigeration also has the following characteristics:   

The refrigerant charge is small, which is conducive to environmental protection and lower operating costs. Both the shell side and the tube side of the tube heat exchanger have large volumes. To make the refrigeration system work normally, a large amount of refrigerant must be filled, and it may also cause environmental pollution.The plate heat exchanger is a highly efficient and compact heat exchange equipment.  

Hope that the introduction of plate heat exchangers can be helpful to you, follow us for more news! If you don’t understand those aspects, you can consult us and we will have professionals to answer you.  Low freezing tendency and high frost resistance  Because the water at low flow rate, it can form a high degree of turbulence in the plate heat exchanger, and the temperature distribution is very uniform, thereby reducing the freezing tendency of the chilled water. Therefore, strengthening the heat transfer of refrigeration heat exchangers, reducing weight and volume, and reducing metal consumption have always been the development direction of refrigeration technology.

Therefore, the plate heat exchanger has been used in petroleum, chemical, light industry, electric power, metallurgy, machinery, energy and other industrial fields. And metal consumption accounts for more than 50% of the entire refrigeration device, and it will also have a significant impact on the refrigeration performance. And easy to achieve unitization, simple and convenient installation, maintenance and transportation can save costs and reduce costs. A new, fully welded plate heat exchanger Brazed Plate Heat Transfer FHC018 has appeared in refrigeration technology

These ripples will bring some resistance to the flow of the medium

 But what exactly is the resistance of the plate heat exchanger? In fact, on the plates of the plate heat exchanger, everyone can see some ripples. Let us understand it together~  First of all, let’s Let’s take a brief look at the plate heat exchanger. These ripples will bring some resistance to the flow of the medium in our plate heat exchanger, but these resistances are not obvious because the plates of the plate heat exchanger The biggest function of the ripples is to block the flow of fluid, thereby reducing the flow rate of the fluid, so that the heat exchange can be more adequate.

Today, plate heat exchanger manufacturers will talk about the resistance of plate heat exchangers. Features too. Just as high heat transfer coefficient, small footprint, light weight, low fouling coefficient, flexible assembly, convenient maintenance, etc. We can say that the plate heat exchanger is a kind of heat exchange equipment that is stacked by pressing and corrugated thin metal heat exchange plates.

There are many ways to water to water heat exchanger company reduce the resistance of plate heat exchangers, but there are not many people who know about resistance. have become the reasons for the popularity of plate heat exchangers.   Hope that the introduction of plate heat exchanger manufacturers can be helpful to you, follow us for more news! If you don’t understand those aspects, you can consult us and we will have professionals to answer you!. Although we said in the summary It is relatively simple, but one thing we all know is that our plate heat exchanger has many advantages. This is the main reason for our plate heat exchangers

The heated air passes through the annular flow channel

In order to enhance the convective fine copper heat exchanger on the air side of the heat exchanger (or on both sides of air and flue gas), a jet flow heat exchanger has been studied and developed. There are many types of such heat exchangers, mainly divided into two types of tube type and barrel type. Sleeve type jet flow heat exchanger, each heat exchanger is composed of dozens or even hundreds of single tubes. Each single tube is composed of two concentric circular sleeves.

Cold air is ejected from many small holes in the inner tube at a flow rate of 20 m / s; the air flow is sprayed on the heat transfer surface of the outer tube. Due to the high air flow velocity, it also destroys the laminar bottom layer on the outer tube wall, which greatly improves the convection heat transfer coefficient of the heat exchanger. Its comprehensive heat transfer coefficient is much higher than that of the ordinary tube heat exchanger, up to 50W 1112. ° C). Moreover, the air preheating temperature is increased, the heat taken away by the tube wall is much, and the temperature is decreased, which is conducive to improving the life of the heat exchanger.

The heated air passes through the annular flow channel between the inner and outer pipes, merges into the wind box and is sent out. In order to ensure that the metal heat exchanger will not be burnt due to excessive temperature or wind stop, the heat exchanger is often equipped with a flue to adjust the amount of exhaust gas.

When the temperature is too high, you can use the method of sucking cold air to reduce the temperature of the exhaust gas, or take the measure of dissipating the hot air of the heat exchanger to avoid the heat exchanger wall temperature being too high.There are many types of heat exchangers, but according to the principles and methods of heat exchange between cold and hot fluids, they can be basically divided into three categories: partition wall heat exchangers, hybrid heat exchangers and regenerative heat exchangers. Among these three types of heat exchangers, the partition wall heat exchanger is the most used, and this type of heat exchanger is also mostly used in the SOFC system.
