[0002] During the pickling process of stainless steel, a certain amount of waste gas will be generated. In the process of waste gas treatment, a plate heat exchanger will be used to exchange heat for the generated waste gas;

[0003] The existing plate heat exchanger for SCR treatment of stainless steel pickling waste gas is also prone to problems of being inconvenient to use during use;

[0004] The reason for this problem is that the plate heat exchanger generally has fixed plates on both sides, and multiple groups of plates are arranged between the fixed plates. The plates can disperse the incoming cold and hot fluids, and perform heat exchange through the plates, thereby achieving the purpose of heat exchange. During the heat exchange process, the number of plates and the distance between the plates directly affect the speed of cold and hot fluid exchange. The more plates there are, the faster the cold and hot fluid exchange speed is. Conversely, the fewer plates, the slower the speed is. During use, it is not convenient to adjust the distance between the plates and the number of plates as needed, which makes it inconvenient to use. In view of the shortcomings of the existing technology, we propose a plate heat exchanger for SCR treatment of stainless steel pickling waste gas to solve the above problems. Utility Model Content

The plate adjustment unit 3 includes multiple groups of driving members 302. When working, cold and hot fluids enter the interior of the device. The cold and hot fluids can be reasonably dispersed by the multiple groups of plates, so that the cold and hot fluids flow in each plate, and the purpose of heat exchange is achieved by heat exchange through the plates. One end of the multiple groups of second plates 202 is slidably connected to the multiple groups of driving members 302, and the plate adjustment unit 3 has the function of adjusting the separation of the first plate 201 and the second plate 202; before use, the multiple groups of first plates 201 and the second plates 202 are in a state of mutual contact.
