[0001] The utility model belongs to the technical field of flue gas treatment, and particularly relates to a flue gas treatment device for a gas boiler. Background Art

[0002] A gas boiler is a device that uses natural gas or liquefied petroleum gas as fuel to convert the heat generated by combustion into hot water or steam, and is widely used in heating, supplying hot water for living and industrial production, and driving certain technological processes. Due to its high efficiency, environmental protection and energy-saving characteristics, the gas boiler occupies an important position in modern energy utilization. The flue gas treatment device of a gas boiler refers to the equipment installed in the boiler flue system for purifying and recovering the heat and harmful substances in the flue gas. These devices are designed to reduce the pollutants emitted into the atmosphere, improve the energy utilization efficiency, and meet the requirements of environmental protection regulations.

[0003] The existing flue gas treatment device of a gas boiler filters and intercepts the impurities inside the flue gas through a filter plate to achieve the treatment of the flue gas. Since the filter plate for filtering the impurities in the flue gas inside it is fixed by bolts and cannot be quickly disassembled and replaced, when a large amount of impurities accumulate on the filter plate, the inability to quickly disassemble and replace will make maintenance and cleaning difficult, which requires longer downtime and more complex operations to clean the filter plate, affecting the production efficiency. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies of the prior art, the utility model provides a flue gas treatment device for a gas boiler. Quickly replacing the filter plate can reduce the downtime and operation complexity, making maintenance and cleaning more convenient. The damaged or filter plate with a large amount of accumulated impurities can be quickly disassembled and replaced with a clean or new filter plate, improving the reliability and production efficiency of the equipment.

[0005] To solve the above technical problems, the technical solution adopted by the present utility model is as follows: A flue gas treatment device for a gas boiler, including a treatment box. An intake pipe is arranged in an intake hole opened at the lower end of the right side surface of the treatment box. A solenoid valve I is connected in series in the middle of the intake pipe. An outlet pipe is arranged in an outlet hole opened at the upper end of the treatment box. A solenoid valve II is connected in series in the middle of the outlet pipe. A filter plate is slidably arranged at the lower end inside the treatment box. A handle I is arranged on the front side surface of the filter plate. A quick disassembly and assembly mechanism for quickly disassembling the filter plate is arranged on the front side surface of the treatment box. A heat recovery component is arranged at the upper end inside the treatment box. The quick disassembly and assembly mechanism includes two rotating columns rotatably arranged on the front side surface of the treatment box. Pulling plates are fixedly sleeved on the outer arc surfaces of the two rotating columns. Plug columns are arranged at the rear sides of the two pulling plates. Two slot blocks are arranged on the front side surface of the filter plate. The two plug columns are respectively inserted into the adjacent slot blocks. Limit discs are arranged at the front ends of the two rotating columns. An elastic driving component is arranged between the limit disc and the rotating plate. The elastic driving component includes springs arranged on the outer arc surfaces of the corresponding rotating columns respectively.

[0006] As a further improvement of the present utility model, a support frame is welded and fixed at the lower end of the treatment box, and several installation holes are opened inside the support frame.

[0007] As a further improvement of the present utility model, a control panel is arranged on the front side surface of the treatment box, and both the solenoid valve I and the solenoid valve II are electrically connected to the control panel.

[0008] As a further improvement of the present utility model, the heat recovery component includes heat conduction pipes arranged at the upper end inside the treatment box, and a plurality of heat conduction fins are fixedly sleeved on the outer arc surfaces of the heat conduction pipes.

[0009] As a further improvement of the present utility model, a collection box located below the filter plate is slidably connected to the lower end of the treatment box, and a handle II is arranged on the front side surface of the collection box.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] Firstly, by connecting the water inlet hole on the left side of the heat conduction pipe to the intake pipe, and then connecting the water outlet hole on the right side of the heat conduction pipe to the outlet pipe, water enters the inside of the heat conduction pipe. Subsequently, the intake pipe is connected to the flue gas pipe to be treated, and then by controlling the opening of the solenoid valve I, the flue gas enters the inside of the treatment box. The flue gas moves upward and passes through the filter plate to filter and intercept impurities inside it. The filtered flue gas continues to move upward. Since the flue gas is a high-temperature gas, it cooperates with the heat conduction fins on the heat conduction pipe to heat the water inside the heat conduction pipe. Then, by controlling the opening of the solenoid valve II, the heated high-temperature flue gas is discharged from the outlet pipe. After the water inside the heat conduction pipe is heated to an appropriate temperature, it flows out from the water outlet hole into the inside of the intake pipe for subsequent utilization.

[0012] Second, after the impurities inside the flue gas are filtered by the filter plate, some impurities adhere to the lower end of the filter plate, and some impurities fall into the interior of the collection box under the influence of gravity. Personnel can pull out the collection box through the second handle, facilitating the handling of the impurities inside.

[0013] Third, by pulling and rotating the pull plate, the insertion post at its upper end is removed from the inside of the locking groove. Continuing to rotate the pull plate to move it away from the surface of the filter plate, then pulling out the filter plate through the first handle and inserting a new filter plate into the interior of the treatment box. Then, pulling and rotating the pull plate, at this time the spring is in a compressed state, causing the pull plate to rotate to the surface of the filter plate, making the insertion post at its upper end correspond to the position of the locking groove. Then release the pull plate, and at this time the spring quickly rebounds to drive the insertion post to insert into the interior of the locking groove, completing the rapid disassembly, installation, and replacement of the filter plate. Quickly replacing the filter plate can reduce the downtime and operation complexity, making maintenance and cleaning more convenient. The damaged or highly contaminated filter plate can be quickly removed and replaced with a clean or new one, improving the reliability and production efficiency of the equipment.

[0014] Fourth, the flue gas treatment device information can be installed through the mounting holes on the support frame, preventing it from shifting during operation and making the operation of the flue gas treatment device more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To better understand the present utility model, the content of the present utility model will be further clearly elaborated below in conjunction with embodiments. However, the protected content of the present utility model is not limited to the following embodiments. In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0022] As Figure 1 , 2 , 3, and 4 show, the flue gas treatment device of a gas boiler includes a treatment box 101. An intake pipe 107 is arranged in the intake hole opened at the lower end of the right side surface of the treatment box 101. A first electromagnetic valve 106 is connected in series in the middle of the intake pipe 107. An outlet pipe 109 is arranged in the outlet hole opened at the upper end of the treatment box 101. A second electromagnetic valve 108 is connected in series in the middle of the outlet pipe 109. A filter plate 104 is slidably arranged at the lower end inside the treatment box 101. A first handle is arranged on the front side surface of the filter plate 104. A quick disassembly and assembly mechanism for quickly disassembling the filter plate 104 is arranged on the front side surface of the treatment box 101. A heat recovery assembly is arranged at the upper end inside the treatment box 101. The heat recovery assembly includes a heat conduction pipe 301 arranged at the upper end inside the treatment box 101. A plurality of heat conduction fins 302 are fixedly sleeved on the outer arc surface of the heat conduction pipe 301.

[0023] As Figure 1 , 2 , 3 show, the quick disassembly and assembly mechanism includes two rotating columns 206 rotatably arranged on the front side surface of the treatment box 101. Pulling plates 201 are fixedly sleeved on the outer arc surfaces of the two rotating columns 206. Plug columns 205 are arranged at the rear sides of the two pulling plates 201. Two slot blocks 203 are arranged on the front side surface of the filter plate 104. The two plug columns 205 are respectively inserted into the adjacent slot blocks 203. Limit disks 202 are arranged at the front ends of the two rotating columns 206. An elastic driving assembly is arranged between the limit disk 202 and the rotating plate. The elastic driving assembly includes springs 204 arranged. The two springs 204 are respectively sleeved on the outer arc surfaces of the corresponding rotating columns 206.

[0024] As Figure 1 , 2 shown, a collection box 105 located below the filter plate 104 is slidably connected to the lower end of the treatment box 101. A second handle is arranged on the front side surface of the collection box 105.

[0025] As Figure 1 , 2 shown, a control panel 401 is arranged on the front side surface of the treatment box 101. The first electromagnetic valve 106 and the second electromagnetic valve 108 are both electrically connected to the control panel 401

[0026] By connecting the inlet pipe to the left water inlet hole of the heat conduction pipe 301 and then connecting the outlet pipe to the right water outlet hole of the heat conduction pipe 301, water is made to enter the interior of the heat conduction pipe 301. Subsequently, the inlet gas pipe 107 is connected to the flue gas pipe to be processed, and then the solenoid valve 106 is controlled to open through the control panel 401, enabling the flue gas to enter the interior of the treatment tank 101. The flue gas moves upward and passes through the filter plate 104 to filter and intercept the impurities inside. The filtered flue gas continues to move upward. Since the flue gas is a high-temperature gas, it cooperates with the heat conduction fins 302 on the heat conduction pipe 301 to heat the water inside the heat conduction pipe 301. Then, the solenoid valve 108 is controlled to open through the control panel 401, allowing the heated high-temperature flue gas to be discharged from the outlet pipe 109. After the water inside the heat conduction pipe 301 is heated to an appropriate temperature, it flows out of the water outlet hole into the interior of the outlet pipe for subsequent utilization.

[0027] After the impurities inside the flue gas are filtered by the filter plate 104, some impurities adhere to the lower end of the filter plate 104, and some impurities fall into the interior of the collection box under the influence of gravity. Personnel can pull out the collection box through the handle two to process the impurities inside.

[0028] When the filter plate 104 needs to be replaced, by pulling and rotating the pull plate 201, the plug post 205 at its upper end is made to leave the interior of the locking groove. Continuing to rotate the pull plate 201 makes it leave the surface of the filter plate 104. Then, the filter plate 104 is pulled out through the handle one, and a new filter plate 104 is inserted into the interior of the treatment tank 101. Then, the pull plate 201 is pulled and rotated. At this time, the spring 204 is in a compressed state, causing the pull plate 201 to rotate to the surface of the filter plate 104, making the plug post 205 at its upper end correspond to the position of the locking groove. Then, the pull plate 201 is released. At this time, the spring 204 quickly rebounds to drive the plug post 205 to insert into the interior of the locking groove, completing the quick disassembly, installation, and replacement of the filter plate 104.

[0029] According to another embodiment of the present invention, as Figure 1 shown, a support frame 102 is fixedly welded to the lower end of the treatment tank 101. A plurality of mounting holes 103 are provided inside the support frame 102. The flue gas treatment device information can be installed through the mounting holes 103 on the support frame 102 to prevent the situation of displacement during its operation.
