Description

Technical Field

[0001] This invention belongs to the field of flue gas detection technology, and in particular relates to a flue gas detection device for boilers. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. With the increasing awareness of environmental protection, the emission of boiler flue gas has become increasingly strict. The pollutants contained in boiler exhaust gas include soot, sulfur dioxide, nitrogen oxides and flue gas opacity. Excessive emission of boiler exhaust gas will aggravate air pollution.

[0003] Therefore, before boiler exhaust gas is emitted, the dust in the filtered exhaust gas needs to be tested. Currently, in the process of testing the content of exhaust gas in boiler flue gas, the detection probe is placed at a dedicated flue gas detection exhaust port. However, when testing larger diameter flue pipes, multiple detection ports need to be set around the same horizontal position of the flue pipe. This requires repeated installation and removal of dust detectors, which is tedious and inefficient. At the same time, it is usually necessary to test the dust at different positions of the flue pipe in order to more accurately assess the pollutant content in the smoke. This operation requires multiple tests, which is also inefficient. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a flue gas detection device for boilers. Multiple sets of control and detection components can be arranged horizontally in a circular pattern to realize the detection of multiple sets of dust at the same horizontal position of a large-diameter flue pipe. At the same time, they can be arranged in opposite directions to be placed vertically to realize the detection of dust at different heights at the same vertical position of the flue pipe.

[0005] The technical solution adopted in this invention is as follows: a flue gas detection device for boilers, including a fixed connecting rod;

[0006] A control disc is movably mounted on the fixed connecting rod. The control disc is made of a lightweight material. There are multiple sets of control discs, which are sequentially and movably sleeved on the fixed connecting rod. The control discs arranged along the fixed connecting rod from bottom to top are named control disc one, control disc two, ..., control disc N.

[0007] Each set of control panels is connected to a control detection component on its side wall. The control detection component is made of a lightweight material. The control detection components arranged from bottom to top along the fixed connecting rod are named control detection component one, control detection component two, ... control detection component N. Control detection component one is connected to the side wall of control panel one, control detection component two is connected to the side wall of control panel two, ... control detection component N is connected to the side wall of control panel N.

[0008] A connecting rope is provided between two adjacent sets of control discs. The connecting rope has a certain elasticity. The upper wall of control disc one is connected to the bottom wall of control disc two through the connecting rope. The upper wall of control disc two is connected to the bottom wall of control disc three through the connecting rope, and so on.

[0009] When inspecting a large exhaust pipe, multiple flue gas detectors need to be set up around the same horizontal position of the exhaust pipe. Control disc two is locked inside control disc one, control disc three is locked inside control disc two, and so on, control disc N is locked inside control disc N-1. Multiple sets of control and detection components are arranged in a ring around the fixed connecting rod. Within the allowable error range, multiple angles and multiple sets of detections are performed on exhaust pipes in the same plane.

[0010] When flue gas needs to be tested at different heights of the exhaust pipe, multiple sets of control and detection components are vertically installed on one side of the fixed connecting rod. Under the action of the connecting rope, they are connected to each other to perform multiple tests at different heights of the exhaust pipe.

[0011] Furthermore, multiple sets of the aforementioned control and detection components are equipped with strip-shaped limiting components that can be movably engaged. The setting of the strip-shaped limiting components can make multiple sets of control and detection components fixed on the same vertical plane, which is convenient for detecting smoke and dust at different heights of the same exhaust pipe.

[0012] The control panel is provided with slots, the number of which decreases by one from control panel one to control panel N, and the number of slots on control panel one is one less than the total number of control panels. The slots are used to receive the control panel above it. Control panel two is movably engaged within control panel one. Control detection component two is movably engaged through the slots on control panel one. The slots on control panel two are positioned corresponding to the slots on control panel one. Control panel three is movably engaged within control panel two. Control detection component three is movably engaged through the slots on control panel one and control panel two. The slots on control panel three are positioned corresponding to the slots on control panel two and control panel one. ... Control panel N is movably engaged within control panel N-1. Control detection component N is movably engaged through the slots on control panel one. ... The slots on control panel N-1 ... ... are positioned corresponding to the slots on control panel one.

[0013] Preferably, the structures of the control and detection components one, two, ... N are all the same, so only one set will be described. The control and detection component one includes a control and detection plate one, which is connected to one side wall of the control disk. The control and detection plate one is a hollow chamber structure with open side walls. The upper and lower walls of the control and detection plate one are mesh structures to facilitate the passage of smoke and dust. The inner side wall of the control and detection plate one is equipped with a smoke detector for detecting the entry and exit of smoke in the exhaust pipe.

[0014] In a preferred embodiment of the present invention, both the upper and lower ends of the fixed connecting rod are fixedly connected to limit disks, the lower end of the fixed connecting rod is equipped with a fixed disk, the bottom wall of the first regulating disk is movably connected to the upper wall of the fixed disk, and the first regulating disk can rotate along the upper wall of the fixed disk to adjust the position of the first regulating disk.

[0015] The strip-shaped limiting member is provided with limiting grooves. There are multiple sets of limiting grooves. The limiting grooves arranged from bottom to top along the strip-shaped limiting member are named limiting groove one, limiting groove two, ... limiting groove N. The number of limiting grooves is the same as the number of control discs. The width of the limiting groove is slightly higher than the thickness of the control detection plate. When multiple sets of control discs are in a vertical state, that is, when the connecting ropes are all in a vertical state, the distance between the control discs is the same as the distance between the limiting grooves.

[0016] In a preferred embodiment of the present invention, the control disc is a hollow cavity with an open top.

[0017] The beneficial effects of the present invention after adopting the above structure are as follows:

[0018] (1) When testing a larger exhaust pipe, multiple flue gas detectors need to be set up around the same horizontal position of the exhaust pipe. Control plate two is locked inside control plate one, control plate three is locked inside control plate two, ... control plate N is locked inside control plate N-1. Multiple control and detection components are arranged in a ring around the fixed connecting rod. Within the allowable error range, multiple angles and multiple groups of tests are performed on exhaust pipes in the same plane.

[0019] (2) When it is necessary to perform flue gas detection at different heights of the flue pipe, multiple sets of control and detection components are set vertically on one side of the fixed connecting rod and connected to each other under the action of the connecting rope to perform multiple sets of detection at different heights of the flue pipe.

[0020] (3) The rotating control plate drives the control detection component on it to rotate, so that the control detection plate on the control detection component can be locked in the limiting groove. Under the action of the limiting groove, multiple control detection plates are set on the same vertical plane. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0035] like Figures 1-10 As shown, a boiler flue gas detection device includes a fixed connecting rod 1; a control disc 2 is movably mounted on the fixed connecting rod 1. The control disc 2 is made of a lightweight material, and multiple sets of control discs 2 are arranged, which are sequentially movably sleeved on the fixed connecting rod 1. The control discs 2 arranged along the fixed connecting rod 1 from bottom to top are named control disc one 3, control disc two 4... control disc N5; a control detection component 6 is connected to the side wall of each control disc 2. The control detection component 6 is made of a lightweight material, and the control detection components 6 arranged along the fixed connecting rod 1 from bottom to top are named control detection component one 7, control detection component two 8... control detection component N9. Control detection component one 7 is connected to the side wall of control disc one 3, control detection component two 8 is connected to the side wall of control disc two 4... control detection component N9 is connected to the side wall of control disc N5; a connecting rope 10 is provided between adjacent sets of control discs 2. 10 has a certain degree of elasticity. The upper wall of the control plate 1 3 is connected to the bottom wall of the control plate 2 4 through the connecting rope 10. The upper wall of the control plate 2 4 is connected to the bottom wall of the control plate 3 through the connecting rope 10, and so on. When testing a larger exhaust pipe, multiple smoke detectors 14 need to be set around the same horizontal position of the exhaust pipe. The control plate 2 4 is locked inside the control plate 1 3, the control plate 3 is locked inside the control plate 2 4, and so on. The control plate N5 is locked inside the control plate N-1. Multiple sets of control and detection components 6 are arranged in a ring around the fixed connecting rod 1. Within the allowable error range, multiple sets of tests are performed on exhaust pipes in the same plane at multiple angles. When smoke detection is required at different heights of the exhaust pipe, multiple sets of control and detection components 6 are arranged vertically on one side of the fixed connecting rod 1. Under the action of the connecting rope 10, they are connected to each other to perform multiple sets of tests at different heights of the exhaust pipe. The control plate 2 is a hollow cavity with an open top.

[0036] Multiple sets of control and detection components 6 are movably engaged with strip-shaped limiting members 11. The setting of the strip-shaped limiting members 11 can make multiple sets of control and detection components 6 fixed on the same vertical plane, which is convenient for detecting smoke and dust at different heights of the same exhaust pipe. The strip-shaped limiting members 11 are provided with limiting grooves 17. There are multiple sets of limiting grooves 17. The limiting grooves 17 arranged from bottom to top along the strip-shaped limiting members 11 are named limiting groove one, limiting groove two... limiting groove N. The number of limiting grooves 17 is the same as the number of control discs 2. The width of the limiting grooves 17 is slightly higher than the thickness of the control and detection plate. When multiple sets of control discs 2 are in a vertical state, that is, when the connecting ropes 10 are all in a vertical state, the distance between the control discs 2 is the same as the distance between the limiting grooves 17. Rotating the control disc 2 drives the control and detection components 6 on it to rotate, so that the control and detection plates on the control and detection components 6 can be engaged in the limiting grooves 17. Under the action of the limiting grooves 17, multiple sets of control and detection plates are set on the same vertical plane.

[0037] The control panel 2 is provided with a slot 12. The number of slots 12 decreases by one from control panel 3 to control panel N5, and the number of slots 12 on control panel 3 is one less than the total number of control panels 2. The slots 12 are used to receive the control panel 2 above it. Control panel 2 4 is movably engaged within control panel 3. Control detection component 2 8 is movably engaged through the slot 12 on control panel 3. The slots 12 on control panel 2 4 are positioned corresponding to the slots 12 on control panel 3. Control panel 3 is movably engaged within control panel 2 4. Control detection component 3 is movably engaged through both the slots 12 on control panel 3 and control panel 2 4. The slots 12 on control panel 3 and control panel 2 4 are movably engaged. The positions of the slots 12 on the control panel 3 are correspondingly set... The control panel N5 is movablely connected to the control panel N-1, and the control detection component N9 is movablely connected through the slot 12 on the control panel 3... The slot 12 on the control panel N-1, and the positions of the slot 12 on the control panel N-1... the slot 12 on the control panel 3 are correspondingly set; for example, if there are 15 sets of control panels, then the number of slots 12 on the control panel 3 is 14 sets. The control detection component 7 connected to the side wall of the control panel 3 and the 14 sets of slots 12 are evenly set on the control panel 3 at 360 degrees, and the angle between each set of slots 12 is 24 degrees; the number of slots 12 on the control panel 4 is 13 sets, and the control detection component 7 connected to the side wall of the control panel 3 is evenly set on the control panel 3 at 360 degrees, with the angle between each set of slots 12 being 24 degrees; the number of slots 12 on the control panel 4 is 13 sets, and the side wall of the control panel 4 is connected to... The control detection component 2 (8) and 13 sets of slots 12 are arranged in an arc shape with equal intervals on the control disk 2 (4). The angle of the control detection component 2 (8) and 13 sets of slots 12 is the same as the angle between the slots 12 on the control disk 1 (3), both being 24 degrees. Therefore, the slots 12 on the control disk 2 (4) are not distributed along the control disk 2 (4) in a 360-degree pattern. The control disk 3 has 12 sets of slots 12. The control detection component 3 connected to the side wall of the control disk 3 and the 12 sets of slots 12 are arranged in an arc shape with equal intervals on the control disk 3. The angle of the control detection component 3 and the 12 sets of slots 12 is the same as the angle between the slots 12 on the control disk 1 (3), both being 24 degrees. Therefore, the slots 12 on the control disk 3 are not distributed along the control disk 3 in a 360-degree pattern. The number of slots 12 on the control panel fourteen is 1, and the acute angle between the control panel fourteen and the slot 12 is 24 degrees; the number of slots 12 on the control panel fifteen is 0; the structures of the control detection components one 7, control detection components two 8... control detection components N9 are all the same, so only one set will be introduced. The control detection component one 7 includes a control detection plate one 13, which is connected to the side wall of the control panel one 3. The control detection plate one 13 is a hollow chamber structure with open side walls. The upper and lower walls of the control detection plate one 13 are mesh structures to facilitate the passage of smoke and dust. The inner side wall of the control detection plate one 13 is equipped with a smoke detector 14 for detecting the entry and exit of smoke in the exhaust pipe.

[0038] Limiting disks 15 are fixedly connected to both the upper and lower ends of the fixed connecting rod 1. A fixed disk 16 is installed at the lower end of the fixed connecting rod 1. The bottom wall of the control disk 3 is movably connected to the upper wall of the fixed disk 16. The control disk 3 can rotate along the upper wall of the fixed disk 16 to adjust the position of the control disk 3.

[0039] The specific usage is as follows:

[0040] Assuming there are 15 sets of control panels 2, the number of slots 12 on control panel 3 is 14 sets. The control detection component 7 connected to the side wall of control panel 3 and the 14 sets of slots 12 are evenly arranged at 360 degrees on control panel 3, with an angle of 24 degrees between each set of slots 12. Similarly, the number of slots 12 on control panel 4 is 13 sets. The control detection component 8 connected to the side wall of control panel 4 and the 13 sets of slots 12 are evenly arranged in an arc shape at equal intervals on control panel 4. The angle between the control detection component 8 and the 13 sets of slots 12 is the same as the angle between the slots 12 on control panel 3, both being 24 degrees. Therefore, control panel 2... The slots 12 on control panel 4 are not distributed in a 360-degree pattern along control panel 2; control panel 3 has 12 sets of slots 12. The control detection component 3 connected to the side wall of control panel 3 and the 12 sets of slots 12 are evenly spaced in an arc shape on control panel 3. The angle between the control detection component 3 and the 12 sets of slots 12 is the same as the angle between the slots 12 on control panel 13, which is 24 degrees. Therefore, the slots 12 on control panel 3 are not distributed in a 360-degree pattern along control panel 3... Control panel 14 has 1 slot 12, and the acute angle between control panel 14 and slot 12 is 24 degrees; control panel 15 has 0 sets of slots 12.

[0041] When inspecting a large exhaust pipe, multiple flue gas detectors 14 need to be installed around the exhaust pipe at the same horizontal position. The fixed connecting rod 1 is placed upright, and the control disc 1 3 is located at the lower end of the fixed connecting rod 1. Multiple control discs 2 are folded sequentially, with control disc 2 4 placed on control disc 1 3, control disc 3 on control disc 2 4, and so on, with control disc 15 placed on control disc 14. Then, control disc 2 4 is manually rotated so that it is movably engaged within control disc 1 3. The control detection component 2 8 is movably engaged through the slot 12 on control disc 1 3, and the slot 12 on control disc 2 4 corresponds to the slot 12 on control disc 1 3. The control panel is set to be manually rotated so that it is movably engaged within the control panel 4. The control detection component 3 is movably engaged through the slot 12 on the control panel 3 and the slot 12 on the control panel 4. The slot 12 on the control panel 3 corresponds to the slot 12 on the control panel 4 and the slot 12 on the control panel 3. The control panel is set to be manually rotated so that it is movably engaged within the control panel 14. The control detection component 15 is movably engaged through the slot 12 on the control panel 3 and the slot 12 on the control panel 14. The slot 12 on the control panel 14 and the slot 12 on the control panel 3 correspond to the slot 12 on the control panel 3.

[0042] After fifteen sets of control discs 2 are connected in sequence, fifteen sets of control and detection components 6 are evenly arranged in a circular pattern on the same plane. The fixed connecting rod 1 is set on the exhaust pipe to be tested by the limiting disc 15 and the external fixing device. The control and detection components 6, which are arranged in a circular pattern, are set in the exhaust pipe. Within the allowable error range, the smoke and dust in the exhaust pipe on the same plane are tested from multiple angles and in multiple groups.

[0043] When flue gas testing is required at different heights in the exhaust pipe, the fixed connecting rod 1 is placed in reverse, and the control plate 15 is located at the lower end of the fixed connecting rod 1. Under the action of gravity and the connecting rope 10, multiple sets of control and detection components 6 are in a stretched state. Then, the control plate 2 is rotated in sequence, causing the control and detection components 6 on it to rotate, so that the control and detection plates on the control and detection components 6 can be engaged in the limiting groove 17. Under the action of the limiting groove 17, multiple sets of control and detection plates are set on the same vertical plane. At the same time, the connecting rope 10 is in a vertical state, and multiple sets of control and detection components 6 are connected to each other. The fixed connecting rod 1 is set on the exhaust pipe to be tested through the limiting plate 15 and the external fixing device. The control and detection components 6, which are set in a vertical state, are set in the exhaust pipe, and multiple sets of tests are performed on the exhaust pipe at different heights.
