Through the previous explanation of various instruments and equipment, I wonder if you have mastered it? Today we are going to introduce plate heat exchanger. I hope you can read it carefully.
The plate heat exchanger is an efficient heat exchanger made of a series of metal sheets with the same corrugated shape by stacking. A kind of thin rectangular channel is formed between all its plates to exchange heat between plates. Plate heat exchanger is a mechanical equipment for heat exchange between liquid and liquid, gas and liquid. Its main types include frame type and brazed type, and its plate forms mainly include herringbone corrugated plate, horizontal straight corrugated plate and popular plate.
Next, we will introduce its structure and principle. The removable plate heat exchanger is made of a lot of stamped corrugated sheets, which are sealed by plates at a certain distance interval, and are made by overlapping and pressing with frame and pressing screw. The inner corner holes in the plates and gaskets become the distribution of fluid. The common pipes and the collecting pipes can reasonably separate the hot and cold fluids, so that they can flow in the channels on both sides of different plates, so that the plates can exchange heat.
In our daily work, we can usually classify them according to different methods. According to the more or less heat exchange area in the unit space, the plate heat exchanger is a compact machine, which is mainly compared with the shell-and-tube heat exchanger. Compared with the traditional shell-and-tube heat exchanger, the floor area is very large. Then it can be divided into heater, cooler, condenser and preheater according to the different purposes of the process. It can also be classified by the direction of two different media and the gap width and ripple of the flow channel, and whether it is a complete set.
In a plate heat exchanger, a group of media in the same flow direction flows into the channel. The flow channels of the media composed of two adjacent plates in the plate heat exchanger are different. In general, several channels are connected together in parallel or in series to form different combinations of cold and hot media exchange pipes.
I believe that after reading this article, you should know what plate heat exchanger is and its classification. I hope this article will help you understand this product.
