[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] Reference Figure 1 and 2 5 is the first embodiment of the utility model, which provides a dust removal mechanism that can achieve a dust removal effect, including a dust removal unit 100, which includes a dust removal component 101 installed on the smoke exhaust pipe G and a water spray component 102 arranged on the dust removal component 101.

[0038] Specifically, the dust removal assembly 101 includes a smoke inlet pipe 101a installed on the smoke exhaust pipe G, a tank body 101b arranged at one end of the smoke inlet pipe 101a, a smoke outlet pipe 101c connected to the outer surface of the tank body 101b, and a sewage valve 101d installed at the bottom of the tank body 101b.

[0039] Furthermore, the water spray assembly 102 includes a water spray pipe 102a arranged on a through hole on the outer surface of the tank body 101b, a movable valve 102b installed at one end of the water spray pipe 102a and capable of rotating, a diversion pipe 102c arranged on the movable valve 102b, an atomizing nozzle 102d installed at one end of the diversion pipe 102c, and a water pump unit 102e arranged at one end of the water spray pipe 102a to provide a water source.

[0040] More preferably, the water spray pipe 102a is connected to the tank body 101b, and the outer side of the tank body 101b is coated with sealant to be sealed.

[0041] There are four shunt pipes 102c in total, and a circular array is arranged on the outer surface of the movable valve 102b, and the shunt pipes have a folded angle of 45°.

[0042] Furthermore, water is sprayed out through the atomizing nozzle 102d installed at one end of the diverter pipe 102c, which can generate thrust to drive the diverter pipe 102c and the movable valve 102b to rotate.

[0043] In summary, when in use, water is first supplied to the movable valve from the water spray pipe 102a through the water pump unit 102e, and then the water is diverted to the diversion pipe 102c through the movable valve 102b, and finally the water is atomized and sprayed out through the atomizing nozzle 102d, so that the water mist is integrated with the large particles of impurities in the flue gas. Because the water mist sprayed out by the atomizing nozzle 102d will generate thrust, the diversion pipe 102c and the movable valve 102b will rotate, and the sprayed water mist can be rotated and sprayed to better integrate with the large particles of impurities in the flue gas. Finally, the treated hot gas can be discharged through the smoke outlet pipe 101c.

[0044] Example 2

[0045] Reference Figures 3 to 6 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a water outlet valve assembly 103 and a sewage collection box assembly 104 matched therewith, which solves the problem that sewage is deposited in the tank body 101b and cannot be treated. It includes a support column 103a installed on the inner wall of the tank body 101b, a pull rod 103b arranged on the outer surface of the support column 103a, a transmission component 103c extending from one end of the support column 103a, a linkage component 103d arranged on the transmission component 103c, and a sewage collection box assembly 104 matched therewith.

[0046] Specifically, a limiting hole 103b-1 is provided on the pull rod 103b disposed on the outer surface of the support column 103a.

[0047] Furthermore, the transmission component 103c includes a movable hole 103c-1 installed on the outer surface of the support column 103a, a guide column 103c-2 rotatably arranged inside the movable hole 103c-1, a starting rod 103c-3 connected to one end of the guide column 103c-2, a slide groove 103c-4 opened on the starting rod 103c-3, a float arm 103c-5 installed at one end of the guide column 103c-2, and a float 103c-6 connected to one end of the float arm 103c-5, wherein the float is hollow and made of a material that is easy to float, and polypropylene is preferably used.

[0048] More preferably, the linkage component 103d includes a steel rope 103d-1 and a ball plug 103d-2 disposed at one end of the steel rope 103d-1, wherein the ball plug 103d-2 is made of rubber.

[0049] Among them, the steel rope 103d-1 can be installed on the slide groove 103c-4, and can move freely along the X-axis direction on the slide groove 103c-4, and the steel rope 103d-1 can slide up and down along the Y-axis direction in the limiting hole 103b-1.

[0050] It should be noted that the buoyancy of the float 103c-6 is F1, the buoyancy of the ball plug 103d-2 is F2, the gravity is G, and the suction force of the drain valve 101d is P. When the water in the tank 101b does not touch the float 103c-6, F2 is less than P+G. When the water in the tank 101b touches the float 103c-6, F1+F2>P+G, and the buoyancy of the float 103c-6 can drive the ball plug 103d-2 to move.

[0051] Preferably, a floating arm 103c-5 and a floating ball 103c-6 connected at one end may be symmetrically arranged on the other side of the starting rod 103c-3.

[0052] Furthermore, the sewage collection box assembly 104 includes a box body 104a disposed outside the sewage valve 101d, a through hole 104b disposed on the top of the box body 104a, and a cleaning door 104c disposed on one side of the box body 104a.

[0053] In summary, during use, when the amount of sewage in the tank body 101b is large enough, the buoyancy can drive the float 103c-6 to float, so that the float arm 103c-5 connected to the float 103c-6 drives the starting rod 103c-3 connected to it to rotate around the movable hole 103c-1 as the center through the guide column 103c-2, so that the steel rope 103d-1 installed on the slide groove 103c-4 opened by the starting rod 103c-3 drives the ball plug 103d-2 to move, so that the sewage can be discharged from the drain valve 101d to the sewage collection box assembly 104, and then the sewage can be cleaned by opening the cleaning door, thereby solving the problem of sewage being deposited in the tank body 101b and unable to be treated.

[0054] Example 3

[0055] Reference Figure 7 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a heat recovery device to solve the problem that a large amount of heat in the flue gas cannot be recovered. It includes the above-mentioned dust removal mechanism and a heat recovery unit 200 installed on the outside of the tank body 101b, which includes a hot water pump assembly 201, an air heating pipe assembly 202 installed on the outside of the hot water pump assembly 201, and a hot water heating pipe assembly 203 installed on the outside of the hot water pump assembly 201.

[0056] Specifically, the air heating pipe assembly 202 includes an air heating plate 202a installed on the hot water pump assembly 201 and extending toward the inside of the tank body 101b, a first water inlet pipe 202b connected to one end of the air heating plate 202a, and a first water return pipe 202c connected to one end of the air heating plate 202a.

[0057] Furthermore, the hot water heating pipe assembly 203 includes a hot water heating plate 203a installed on the hot water pump assembly 201 and extending toward the inside of the tank body 101b, a second water inlet pipe 203b connected to one end of the hot water heating plate 203a, and a second water return pipe 203c connected to one end of the hot water heating plate 203a.

[0058] Among them, the materials of the heating tube include copper tube, aluminum tube and glass tube, and copper tube is preferred.

[0059] In summary, when in use, the hot water pump assembly provides water to the first water inlet pipe 202b and the second water inlet pipe 203b, and heats the air heating plate 202a through the high-temperature flue gas, so that the water source in the water pipe is heated, and the hot water is recovered through the first return pipe 202c, and the hot water after dust removal and fusion is collected at the bottom of the tank body 101b, so that the hot water heating plate 203a arranged in the tank body 101b is heated, and the hot water is recovered through the second return pipe 203c. Because the flue gas has less heat loss during the diversion process, it maintains good waste heat recovery. Then, through the hot water heating pipe assembly, the hot water after dust removal and fusion can be secondary heat recovered at the bottom of the tank body, thereby improving the heat recovery efficiency.
