Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment devices, specifically a heat exchange device for waste gas treatment. Background Technology

[0002] Waste gas treatment refers to the process of purifying waste gas emitted from industrial production, transportation, catering fumes, and other activities through physical, chemical, or biological methods to remove pollutants, reduce harm to the environment and human health, and ensure compliance with national or local emission standards.

[0003] These exhaust gases also contain residual heat. If they are directly discharged into the atmosphere, it will result in a waste of heat. Therefore, heat exchange devices are now used to exchange the heat before the exhaust gases are discharged into the atmosphere, so that the heat can be used to heat water or as other heat sources.

[0004] The prior art patent document CN221403996U discloses a heat exchange device for treating exhaust gas. This heat exchange device is equipped with two heat exchange boxes, and each heat exchange box has multiple staggered heat exchange plates fixed inside. Adjacent heat exchange plates are connected by connecting pipes. The staggered heat exchange plates divide the interior of the heat exchange box into a serpentine exhaust gas flow channel, increasing the contact time between the exhaust gas and the heat exchange plates and greatly improving the heat exchange efficiency. In addition, each heat exchange box has a side door connected to one side by a hinge. By opening the side door, the exhaust gas dust particles attached to the heat exchange plates can be quickly cleaned, ensuring heat exchange efficiency.

[0005] Although the aforementioned prior art uses staggered heat exchange plates to divide the interior of the heat exchange box into a serpentine flow channel for exhaust gas, increasing the contact time between the exhaust gas and the heat exchange plates and greatly improving heat exchange efficiency, the heat exchange devices in this patented technology accumulate dust on the heat exchange plates during long-term use, requiring manual cleaning by staff, which is very cumbersome. It cannot automatically clean the waste dust, reducing the practicality of the heat exchange device. Therefore, we need a heat exchange device for exhaust gas treatment. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A heat exchange device for treating exhaust gas includes an exchange box 1, a water pipe 2 fixedly connected inside the exchange box 1, a cleaning component 3 installed inside the exchange box 1, a filter box 6 installed on one side of the exchange box 1, and a replacement component 8 installed on the top of the filter box 6.

[0027] The cleaning assembly 3 includes a motor 301. The output end of the motor 301 is detachably connected to a first lead screw 302 via a coupling. A first cleaning brush 303 is threadedly connected to the outer surface of the first lead screw 302. A main pulley 304 is fixedly connected to the outer surface of the first lead screw 302. A connecting belt 305 is drivenly connected to the outer surface of the main pulley 304. A secondary pulley 306 is drivenly connected to the inner wall of the connecting belt 305. A second lead screw 307 is fixedly connected to the inner wall of the secondary pulley 306. A second cleaning brush 308 is threadedly connected to the outer surface of the second lead screw 307.

[0028] The replacement component 8 includes a filter screen 801. A positioning groove 802 is provided on one side of the filter screen 801, and a positioning plate 803 is engaged with the inner wall of the positioning groove 802. A fixing plate 804 is fixedly connected to the top of the filter box 6, and a spring 805 is installed on the inner wall of the fixing plate 804. A movable block 806 is installed at one end of the spring 805, and a connecting plate 807 is fixedly connected to the top of the movable block 806.

[0029] Through the above technical solution, starting the motor 301 can drive the first lead screw 302 to rotate and simultaneously drive the first cleaning brush 303 to move, so that the first cleaning brush 303 can clean the heat exchange plate 5. At the same time, under the action of the main pulley 304, the connecting belt 305 and multiple auxiliary pulleys 306, multiple second lead screws 307 can rotate. The second lead screws 307 drive the second cleaning brushes 308 to move synchronously, so that the second cleaning brushes 308 can clean both sides of the heat exchange plate 5, achieving the effect of automatically cleaning the dust on the heat exchange plate 5 without the need for manual operation by the staff, thus improving the practicality of the heat exchange device.

[0030] Specifically, an exhaust pipe 4 is fixedly connected to one side of the exchange box 1, a heat exchange plate 5 is installed inside the exchange box 1, and an air inlet pipe 7 is fixedly connected to one side of the filter box 6.

[0031] The above technical solution facilitates the entry of exhaust gas into the heat exchanger 1 through the intake pipe 7. The heat is absorbed by the heat exchange plate 5 in the heat exchanger 1 and heated by the water pipe 2, so that the water in the water pipe 2 can be heated and used. Finally, the exhaust gas is discharged from the exhaust pipe 4.

[0032] Specifically, the motor 301 forms a moving structure with the first cleaning brush 303 via the first lead screw 302, and the external thread of the first lead screw 302 matches the internal thread of the first cleaning brush 303.

[0033] The above technical solution facilitates the starting motor 301 to drive the first lead screw 302 to rotate while simultaneously driving the first cleaning brush 303 to move, enabling the first cleaning brush 303 to clean the top of the heat exchange plate 5. During the movement, the first cleaning brush 303 will slide synchronously on the slide rod to maintain stability. The slide rod and the first lead screw 302 are symmetrically arranged, achieving the effect of stable movement of the first cleaning brush 303.

[0034] Specifically, the main pulley 304 forms a transmission structure with the auxiliary pulley 306 via the connecting belt 305, and there are multiple auxiliary pulleys 306.

[0035] The above technical solution facilitates the rotation of the first lead screw 302, which in turn drives the main pulley 304 to rotate. The main pulley 304, through the transmission action of the connecting belt 305, drives multiple auxiliary pulleys 306 to rotate synchronously, thus achieving the effect of synchronous rotation of multiple auxiliary pulleys 306.

[0036] Specifically, the auxiliary pulley 306 forms a movable structure with the second cleaning brush 308 via the second lead screw 307, and the external thread of the second lead screw 307 matches the internal thread of the second cleaning brush 308.

[0037] The above technical solution facilitates the rotation of the secondary pulley 306, which in turn drives the second lead screw 307 to rotate, thereby enabling the second lead screw 307 to move the second cleaning brush 308. Both the upper and lower ends of the second cleaning brush 308 are equipped with brushes, which can clean both sides of the heat exchange plate 5.

[0038] Specifically, the filter screen 801 forms a locking structure with the positioning plate 803 through the positioning groove 802, and the shape and size of the positioning groove 802 match the shape and size of the positioning plate 803.

[0039] The above technical solution facilitates the installation of the filter screen 801 inside the filter box 6. The filter screen 801 can be fixed by the positioning plate 803 extending into the positioning groove 802, without the need for bolts for fixing.

[0040] Specifically, the fixed plate 804 forms an elastic structure with the movable block 806 via the spring 805, and one side of the movable block 806 is connected to one side of the positioning plate 803.

[0041] The above technical solution facilitates the movement of the movable block 806 by manually moving the connecting plate 807 outward, which in turn causes the movable block 806 to move the positioning plate 803 outward, disengaging it from the positioning groove 802 and releasing the limiting fixation on the filter screen 801, making it easier to disassemble. When the connecting plate 807 is released, the movable block 806 will move inward under the action of the spring 805, causing the positioning plate 803 to move inward and re-fix the filter screen 801.

[0042] Working Principle: When using this heat exchange device for waste gas treatment, firstly, the drive mechanisms within the device are all powered by an external power supply. Each drive device is controlled by a PLC controller. When cleaning the dust on the heat exchange plate 5, the motor 301 is started first. The motor 301 drives the first lead screw 302 to rotate, which in turn drives the first cleaning brush 303 to move and clean the heat exchange plate 5. Simultaneously, the first lead screw 302 drives the main pulley 304 to rotate, which in turn drives multiple auxiliary pulleys 306 to rotate via a connecting belt 305. This causes the auxiliary pulleys 306 to drive multiple second lead screws 307 to rotate synchronously. The rotation of the second lead screws 307 drives the second cleaning brushes 308 to move, thus cleaning the heat exchange plate. Clean the top and bottom surfaces of plate 5. When replacing filter screen 801, simply move connecting plate 807 outward by hand. Connecting plate 807 drives movable block 806 outward, and movable block 806 drives positioning plate 803 outward to disengage from positioning groove 802, thus releasing the fixation of filter screen 801. Then, pull the old filter screen 801 out of filter box 6 and insert the new filter screen 801 back into filter box 6 for installation. Loosen connecting plate 807, and under the action of spring 805, movable block 806 moves inward, which in turn causes positioning plate 803 to move inward and extend into positioning groove 802 to fix filter screen 801. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
