[0002] A condensing heat exchanger is a device that cools and condenses high-temperature and high-pressure gaseous fluid into liquid fluid. It can transfer the heat in the hot gas to the low-temperature and low-pressure liquid, and recover the heat by exchanging heat on the pipe wall. It has the advantages of high efficiency, energy saving, easy maintenance, and high safety, and is widely used in industrial and civil fields.

[0003] When using an existing condensing heat exchanger, it is necessary to allow various high-temperature flue gases, steam or industrial hot gases to enter the interior of the tube wall.

When the flue gases are discharged from the heat exchanger after the heat exchange is completed, it is easy to pollute the external atmosphere. Therefore, the flue gases need to be filtered, but the dust will remain in the heat exchanger after filtering, which is inconvenient to clean. In order to solve this technical problem, the utility model proposes a condensing heat exchanger with a filtering structure. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

The fixed shell 1 and the movable shell 2 are fixed by bolts and can be disassembled when necessary.

[0024] The inner wall of the movable shell 2 is fixedly connected with a heat absorbing sheet 3, the lower part of which is in contact with the fixed shell 1. The heat absorbing sheet 3 is spiral in shape. When in use, hot air can move along the heat absorbing sheet 3 in a spiral trajectory, thereby increasing the heat exchange efficiency.

[0025] A water baffle 4 is provided on one side of the heat absorbing plate 3, and the outer surface of the water baffle 4 is fixedly connected to the fixed shell 1. A filter plate 5 is fixedly connected to one end of the fixed shell 1. The upper end of the filter plate 5 is detachably connected to the movable shell 2. The upper end of the filter plate 5 can be removed from the movable shell 2. A vibration motor 6 is installed on one side of the filter plate 5. The vibration motor 6 can drive the filter plate 5 to vibrate so as to shake off the dust.

[0026] The lower part of the fixed shell 1 is fixedly connected with a guide plate 7, one side of the guide plate 7 is high and the other side is low, so that the water flow can be gathered to the lower side. The lower part of the guide plate 7 is provided with a water hole, so that the water flow can pass through. The interior of the water baffle 4 is provided with a blocking mechanism 8, and the blocking mechanism 8 includes an arc plate 801, the outer surface of the arc plate 801 is slidably connected to the water baffle 4, and the lower surface of the arc plate 801 is slidably connected to the guide plate 7. The arc plate 801 can block the water hole, and one side of the arc plate 801 is fixedly connected There is a sliding rod 802, the outer surface of the sliding rod 802 is slidably connected to the guide plate 7, the end of the sliding rod 802 away from the arc plate 801 is fixedly connected to the pull plate 803, the outer surface of the sliding rod 802 is sleeved with a spring 804, one end of the spring 804 is fixedly connected to the arc plate 801, and the other end of the spring 804 is fixedly connected to the guide plate 7. The spring 804 gives the arc plate 801 an elastic force so that the arc plate 801 can block the water hole in the absence of external force, thereby increasing convenience.

[0027] A connecting plate 9 is installed on one side of the guide plate 7, and a sewage pipe 10 is installed on one side of the connecting plate 9. The connecting plate 9 can gather water to the position of the sewage pipe 10. A circular plate 15 is fixedly connected to one end of the fixed shell 1 away from the filter plate 5. The upper part of the circular plate 15 is detachably connected to the movable shell 2. An air inlet pipe 11 is fixedly connected to the middle part of the circular plate 15. The air inlet pipe 11 is used for air intake. A support leg 14 is fixedly connected to the lower surface of the fixed shell 1, and the support leg 14 can support the fixed shell 1. A water outlet pipe 12 and a water inlet pipe 13 are respectively installed at both ends of the heat absorbing plate 3, and the outer surfaces of the water outlet pipe 12 and the water inlet pipe 13 are fixedly connected to the fixed shell 1.

[0028] It should be noted that in actual use of the device, hot air enters the interior of the fixed shell 1 and the movable shell 2 from the air inlet pipe 11, and moves toward the direction of the filter plate 5. At the same time, cold water flows from the water inlet pipe 13 to the interior of the heat absorbing plate 3, and flows out from the water outlet pipe 12. The hot air impacts the heat absorbing plate 3, thereby exchanging with the water in the heat absorbing plate 3, so that the gas temperature drops and the liquid temperature rises. The gas after the heat exchange is completed is blown out from the filter plate 5, and the filter plate 5 blocks the dust in the gas, thereby blocking the dust on one side of the filter plate 5, thereby achieving the effect of filtering the gas. After being blocked by the filter plate 5, the dust falls downward to one side of the water retaining plate 4, and at the same time, it is vibrated. The motor 6 drives the filter plate 5 to vibrate, and the dust on the filter plate 5 is shaken off, so as to prevent the filter plate 5 from being blocked. During the movement of hot air, the water vapor in the hot air condenses on the heat absorbing plate 3, and then drips into the inside of the guide plate 7. The condensed water is gathered on the other side of the water baffle 4 away from the dust through the guide plate 7. When it is necessary to drain the water, the sewage pipe 10 is opened first, and the pull plate 803 is pulled to move to one side, so that the bottom of the water baffle 4 is no longer blocked, and the water flows out from the lower part of the water baffle 4 to flush the gathered dust, thereby driving the dust to flow to the outside through the sewage pipe 10, so as to achieve the effect of facilitating the cleaning of the dust.

[0029] When disassembly is required, the bolts on the fixed shell 1 and the movable shell 2 are screwed, so that the movable shell 2 drives the heat absorbing sheet 3 to move upward, thereby moving the heat absorbing sheet 3 upward away from the fixed shell 1, so as to facilitate repair or cleaning of the interior, thereby achieving the effect of easy disassembly.
