DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0019] Example 1:

[0020] Reference Figure 1 、 Figure 2 A vortex tube boiler heat exchanger, 1. A vortex tube boiler heat exchanger, comprising a shell 2, and further comprising: a heat preservation tank 202 arranged on one side of the shell 2, wherein a plurality of baffles 201 are staggered up and down in the shell 2, and the plurality of baffles 201 are evenly distributed in the shell 2; a heat exchange vortex 1 3 is arranged in a snake shape and is arranged in the shell 2; a heat exchange vortex 2 301 is arranged in a spiral shape and is arranged in the heat preservation tank 202; a gas transmission pipe 203, one end of which is connected to the shell The heat exchange vortex 1 301 is fixedly connected to the heat exchange vortex 2 301, and the end of the heat exchange vortex 1 301 away from the heat exchange vortex 2 301 passes through the outside of the shell 2, and the end of the heat exchange vortex 2 301 away from the heat exchange vortex 1 3 passes through the outside of the heat exchange tank 202; the pipe 2 106 is fixedly connected to the shell 2.

[0021] The side wall of the shell 2 is fixedly connected to the filter box 1, the end of the pipe 2 106 away from the shell 2 is connected to the filter box 1, and the side wall of the filter box 1 is fixedly connected to the pipe 1 104; it also includes a filter screen 105 connected to the filter box 1.

[0022] When in use, the water to be heated is pumped into the heat exchange vortex 1 3 and the heat exchange vortex 2 301, and then discharged through the output end of the heat exchange vortex 2 301. Subsequently, the high-temperature flue gas generated when the boiler is working is passed into the filter box 1 through the pipe 1 104. The high-temperature flue gas flows upward in the filter box 1 and is then transported into the shell 2 through the pipe 2 106, so that the high-temperature flue gas exchanges heat with the water in the heat exchange vortex 1 3 when flowing through the shell 2. Since a plurality of partitions 201 are staggered up and down in the shell 2, the flow path and residence time of the high-temperature flue gas in the shell 2 are increased, so that the high-temperature flue gas can fully exchange heat with the water in the heat exchange vortex 1 3, and due to the heat exchange vortex Tube 1 3 is arranged in a serpentine shape, which increases the flow path of water in heat exchange vortex 1 3, thereby enabling water to exchange heat more fully with high-temperature flue gas, thereby improving energy utilization. The high-temperature flue gas transported into shell 2 is then transported into insulation tank 202 through gas pipe 203, which collects the high-temperature flue gas. Then, the high-temperature flue gas collected in insulation tank 202 is heat-exchanged again with the water flowing through heat exchange vortex 2 301. In addition, since heat exchange vortex 2 301 is arranged in a spiral shape, the flow path of water in heat exchange vortex 2 301 is increased, thereby enabling water to exchange heat more fully with high-temperature flue gas, thereby further improving energy utilization.

[0023] At the same time, when the high-temperature flue gas drifts upward in the filter box 1, it contacts the filter 105, so that the particulate impurities carried in the high-temperature flue gas can be filtered out through the filter 105, thereby preventing the particulate impurities from following the high-temperature flue gas into the shell 2 and adhering to the surface of the heat exchange vortex 3, thereby affecting the heat exchange between the high-temperature flue gas and water.

[0024] When the pressure in the insulation tank 202 is greater than the pressure relief value set by the pressure relief valve on the pressure relief pipe 204, the pressure relief valve automatically opens to relieve the pressure, thereby keeping the pressure inside the insulation tank 202 constant, avoiding safety hazards caused by excessive pressure inside the insulation tank 202.

[0025] Example 2:

[0026] Reference Figure 1 、 Figure 2 、 Figure 3 , a vortex tube boiler heat exchanger, which is basically the same as Example 1, furthermore, the inner walls on both sides of the filter box 1 are symmetrically fixedly connected with guide rods 402, and the guide rods 402 are fixedly connected with a limit block 403, and the filter screen 105 is slidably connected to the guide rods 402, and a spring 404 is sleeved on the guide rods 402, one end of the spring 404 is fixedly connected to the limit block 403, and the other end is fixedly connected to the filter screen 105; it also includes a cam 401 for driving the filter screen 105 to slide up and down in the filter box 1, and the cam 401 is rotatably connected in the filter box 1.

[0027] A motor 4 is fixedly mounted on the side wall of the filter box 1 , an output end of the motor 4 passes through the filter box 1 , and a cam 401 is fixedly mounted on the output end of the motor 4 .

[0028] Based on the above, when the vortex tube boiler heat exchanger is in operation, the motor 4 is started, and the motor 4 drives the cam 401 to rotate, so that when the cam 401 contacts the filter 105 during the rotation, the filter 105 will slide upward under the push of the cam 401 and compress the spring 404. Then, when the cam 401 separates from the filter 105, the compressed spring 404 generates a thrust to push the filter 105 to move downward, thereby causing the filter 105 that slides up and down to produce a bump, causing it to shake off the particulate impurities attached to the surface of the filter 105, thereby ensuring the smooth flow of the filter 105 and preventing the filter 105 from being blocked, affecting the filtering treatment of the high-temperature flue gas, and then the cleaned particulate impurities fall to the bottom of the filter box 1.

[0029] Example 3:

[0030] Reference Figure 1 、 Figure 2 A vortex tube boiler heat exchanger is basically the same as that of Example 1, and further, the lower end of the filter box 1 is open, and a cover plate 101 is detachably connected to the lower end of the filter box 1, and a collection tank 102 is opened on the cover plate 101, and the collection tank 102 is located in the filter box 1;

[0031] When cleaning the particulate matter impurities attached to the surface of the filter screen 105, the particulate matter impurities that fall to the bottom of the filter box 1 fall into the collecting tank 102, so that the particulate matter impurities can be cleaned centrally.

[0032] It also includes fixing bolts 103, through which the cover plate 101 is detachably connected to the filter box 1;

[0033] By setting the cover 101 to be detachable, when it is necessary to clean the particulate impurities collected in the collection tank 102, the collection tank 102 can be moved out of the filter box 1 by removing the cover 101, thereby facilitating the cleaning of the particulate impurities collected in the collection tank 102.

[0034] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
