Description
Technical Field
[0001] This utility model relates to the field of waste heat recovery technology, specifically to a partitioned heat exchanger that is easy to disassemble and maintain. Background Technology
[0002] Waste heat recovery refers to the process of recovering and reusing underutilized heat energy during industrial production and energy conversion. This technology can effectively improve energy efficiency, reduce energy consumption, and decrease environmental pollution. Heat exchangers are required for waste heat recovery. In high-energy-consuming industries such as petroleum refining and steel smelting, high-temperature waste gas or cooling water often contains a large amount of recoverable heat. Traditional direct-contact heat exchangers cannot be used due to the risk of fluid mixing, while indirect-contact heat exchangers, by isolating the fluid through solid walls, can transfer waste heat to process water or air for power generation, heating, or warming purposes.
[0003] Most existing indirect heat exchangers are sealed pipe structures. After installation, it is usually impossible to disassemble the outer wall structure of the indirect heat exchanger. After long-term use, dust will accumulate on the internal heat exchange plates or the heat exchange plates will be damaged. It is necessary to open the outer shell to maintain and replace the heat exchange plates. Traditional sealed pipe structures require disassembling and opening the entire outer shell of the indirect heat exchanger, which is troublesome and time-consuming.
[0004] Therefore, it is necessary to provide a new type of indirect heat exchanger that is easy to disassemble and maintain in order to solve the above-mentioned technical problems. Utility Model Content

The baffle plate can fix the position of the heat exchange plates to prevent them from falling.
[0011] Preferably, multiple sets of movable plates and back plates are provided with flow grooves on one side, and multiple sets of flow grooves are provided. A fan is installed on one side of the back plate, and multiple sets of fans are provided. The output end of one side of the multiple sets of fans corresponds to the flow groove.

[0016] Compared with related technologies, the indirect heat exchanger provided by this utility model, which is easy to disassemble and maintain, has the following advantages:
[0017] This utility model provides a partitioned heat exchanger that is easy to disassemble and maintain;
[0018] 1. This utility model can facilitate the maintenance of the indirect heat exchanger by setting a movable plate that can be opened quickly. When it is necessary to maintain the inside of the indirect heat exchanger, the first bolt can be rotated out of the threaded hole of the locking plate by using a tool, the locking connection between the locking plate and the top of the movable plate can be released, and the movable plate can be pulled and opened by manually holding and pulling the handle to expose the inside of the indirect heat exchanger, thereby facilitating the maintenance of the indirect heat exchanger.
[0019] 2. This utility model allows for the disassembly of the interior of the partition wall heat exchanger via a separately removable and replaceable heat exchange plate. When it is necessary to disassemble the interior of the partition wall heat exchanger, a tool can be used to rotate the third bolt, which is then rotated out of the threaded hole of the baffle plate. This releases the baffle plate from one side of the slot. By manually holding and pulling the removal slot, the heat exchange plate is slid through the slot and pulled out from the sleeved transmission pipe, thereby achieving the disassembly of the interior of the partition wall heat exchanger.
