Description

Technical Field

[0001] The invention belongs to the technical field of smoke detection, in particular to a smoke detection device for burning domestic waste. Background Art

[0002] Incineration of domestic waste is a method of high-temperature treatment of waste. Specifically, it refers to the process in which the combustible components in the waste react violently with the oxygen in the air in a high-temperature incinerator, converting into high-temperature combustion gas and stable solid residue, and releasing heat. A large amount of flue gas will inevitably be produced during the incineration process. By detecting these flue gases, abnormal conditions in the flue gas can be discovered in time, such as a sudden increase in pollutant concentration or abnormal emissions caused by equipment failure, which helps to take timely measures to prevent the spread of pollution and deterioration of the situation.

[0003] The utility model patent with announcement number CN218157805U discloses a flue gas detector, including a smoke tube, a collecting chamber of the device is installed inside the smoke tube, and the collecting chamber is fixed by an outwardly extending conduit. The smoke will be collected inside the collecting chamber, and the excess gas will be discharged from the device through the exhaust hole; the conduit can be rotated by the interaction between the cylinder-rack and the internal meshing gear, thereby realizing the lifting and lowering of the collecting chamber, so as to collect smoke components in different parts to meet the needs of the background technology; the collected smoke is transported to the inside of a rotating rod with a hollow cavity through a pipeline, and then dispersed to the inside of each collecting cover through a diversion pipe, and a single detection head is installed on the top of each collecting cover, such as a sulfur dioxide detection head, etc., to divert and detect the smoke separately, and the detected smoke data is output to the detection device through a wire for data collection and fed back to the terminal device.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] When it is necessary to collect smoke from smoke tubes of different sizes, since the specifications of the collection chamber are fixed, if the smoke tube is wider, a large amount of smoke will pass through the gap between the outer edge of the collection chamber and the inner wall of the smoke tube. The flow path of the smoke will be more dispersed, resulting in uneven collection of smoke, leading to deviations in the detection results. In addition, since the detection device usually requires a certain amount of gas sample for analysis and detection, if the smoke is too dispersed, the amount of smoke collected in the collection chamber will be insufficient, thereby extending the time of the entire detection process and affecting the detection efficiency.

[0006] To this end, the present invention provides a domestic waste incineration smoke detection device. Summary of the invention

[0049] Specifically, domestic waste incineration is a method of high-temperature treatment of waste. Specifically, it refers to a process in which the combustible components in the waste react violently with the oxygen in the air in a high-temperature incinerator to convert into high-temperature combustion gas and solid residue with stable properties, and release heat. A large amount of flue gas will inevitably be generated during the incineration process. By detecting these flue gases, abnormal conditions in the flue gas can be discovered in time, such as a sudden increase in pollutant concentration or abnormal emissions caused by equipment failure, which helps to take timely measures to prevent pollution from spreading and worsening. Existing flue gas detection devices are used in When the smoke is collected, the collection chamber is driven into the smoke pipe to collect smoke components in different parts of the smoke pipe. However, when smoke in smoke pipes of different sizes needs to be collected, if the smoke pipe is wide, a large amount of smoke will pass through the gap between the outer edge of the collection chamber and the inner wall of the smoke pipe. The smoke flow path is relatively dispersed, resulting in uneven collection of smoke, which leads to deviations in the detection results. In addition, since the detection device usually requires a certain amount of gas sample for analysis and detection, if the smoke is too dispersed, the amount of smoke collected by the collection chamber will be insufficient, thereby prolonging the time of the entire detection process and affecting the detection efficiency.

[0050] Therefore, when this embodiment is used, it is used for regular inspection or random inspection of flue gas 1 under specific circumstances. The entire inspection process is a short-term inspection, and it is used for flue 1 with a square cross-section. Then, according to the part of the flue 1 of the incinerator that needs to be inspected, the motor 13 is started to drive the threaded cylinder 11 to rotate, so that the threaded rod 214 moves downward, and the sliding rod 213 slides in the inner cavity of the sleeve 12, so that the lifting plate 15 can be raised and lowered, so that the connecting pipe 16 drops to a suitable position. Then, according to the size of the flue 1, the motor 232 is started to drive the gear 29 on one side to rotate, so that the gear ring 28 can be rotated, and then the multiple gears 29 and the connecting rod 231 are rotated, and the connecting rod 231 drives the connecting rod 130 to rotate. When the angle between the connecting rod 130 and the connecting rod 231 changes, the multiple limit rods 24 can slide on the fixed plate 25 at the same time, so that the multiple adjustment blocks 18 are in contact with the inner wall angle of the flue 1. At this time, the shielding cloth The four corners of 17 are stretched to the inner angle of the flue 1. At this time, the shielding cloth 17 can cover the flue 1 to a large extent. The smoke in the flue 1 will be intercepted by the shielding cloth 17 during the rising process, so that the smoke is temporarily gathered under the shielding cloth 17, and then the smoke in the flue 1 is extracted by the air pump 36. At this time, the smoke gathered under the shielding cloth 17 can be more easily extracted. After passing through the branch pipe 26, the connecting pipe 16, and the hose 10, the smoke enters the smoke detector 4 for detection and analysis, and then the shielding cloth 17 is driven to move out of the flue 1; thus, the stretching degree of the shielding cloth 17 can be adjusted according to the size of the flue 1, so that the shielding cloth 17 can intercept the smoke in the flue 1 to a large extent, and then the intercepted smoke is extracted and detected, so that the flow range of the smoke is more concentrated, and a sufficient amount of smoke can be collected more quickly, which shortens the time of the entire detection process and improves the detection efficiency;

[0051] When the shielding cloth 17 intercepts the smoke, if the impact force of the smoke is too great, the edge of the shielding cloth 17 may be lifted and deformed, thereby causing the smoke to flow out from the edge of the shielding cloth 17, which may cause the smoke to be more dispersed. Therefore, when the impact force of the smoke is large, the electric push rod 21 is started to drive the pressing plate 1 22 and the pressing plate 2 23 to rise, and with the cooperation of the pressing plate 3 34 and the pressing plate 4 35, the edge of the shielding cloth 17 is clamped, thereby avoiding the situation that when the shielding cloth 17 intercepts the smoke, the edge of the shielding cloth 17 is lifted and deformed due to the excessive impact force of the smoke, thereby causing the smoke to flow out from the edge of the shielding cloth 17, further ensuring the concentration of the smoke and facilitating extraction. In addition, the pressing plates 1 22, 23, 34 and 35 can slide relatively with the stretching of the shielding cloth 17 to ensure that the edge of the shielding cloth 17 can be clamped.

[0052] The smoke in the smoke duct 1 is then collected and tested, thereby shortening the detection time and improving the detection efficiency. The concentration of the collected smoke is relatively uniform, which improves the detection accuracy. In addition, during the detection process, the electric push rod 21 can be started to drive the pressure plate 1 22 and the pressure plate 2 23 to rise, and with the cooperation of the pressure plate 3 34 and the pressure plate 4 35, the edge of the shielding cloth 17 can be clamped, thereby avoiding the situation in which the edge of the shielding cloth 17 is lifted and deformed due to the excessive impact force of the smoke when the shielding cloth 17 intercepts the smoke, causing the smoke to flow out from the edge of the shielding cloth 17, thereby further ensuring the concentration of the smoke and facilitating extraction.

[0053] Working principle: According to the size of the flue 1, manually rotate the bidirectional threaded rod 19 so that the connecting plates 6 on the left and right sides slide in different directions at the same time, away from or close to each other, until the connecting blocks 7 on both sides can be placed on the upper edge of the flue 1, and then manually rotate the threaded rod 18 to drive the clamping plate 9 to slide, and with the cooperation of the clamping plate 9 and the connecting block 7, they can be clamped with the upper edge of the flue 1, so that the mounting plate 2 can be fixed, thereby realizing the connection between the entire device and the flue 1, and then ensuring the stability during the detection process. According to the part of the flue 1 of the incinerator that needs to be detected, start the motor 13 to drive the threaded barrel 11 to rotate, so that the threaded rod 2 14 moves downward, and the sliding rod 2 13 slides in the inner cavity of the sleeve 12, so that the lifting plate 15 can be raised and lowered, so that the connecting pipe 16 moves down. The smoke in the flue 1 is lowered to a suitable position, and then according to the size of the flue 1, the motor 2 32 is started to drive the gear 29 on one side to rotate, so that the gear ring 28 can be rotated, and then the multiple gears 29 and the connecting rod 2 31 are rotated, and the connecting rod 2 31 drives the connecting rod 1 30 to rotate. When the angle between the connecting rod 1 30 and the connecting rod 2 31 changes, the multiple limit rods 24 can slide on the fixing plate 25 at the same time, so that the multiple adjustment blocks 18 fit the angle of the inner wall of the flue 1. At this time, the four corners of the shielding cloth 17 are stretched to the inner angle of the flue 1. At this time, the shielding cloth 17 can cover the flue 1 in a larger range. The smoke in the flue 1 will be intercepted by the shielding cloth 17 during the rising process, so that the smoke is temporarily gathered under the shielding cloth 17, and then the air pump 36 is used to pump the smoke in the flue 1. The smoke in the smoke duct 1 is extracted. At this time, the smoke gathered under the shielding cloth 17 can be more easily extracted. After the smoke passes through the branch pipe 26, the connecting pipe 16 and the hose 10, it enters the smoke detector 4 for detection and analysis, and then the shielding cloth 17 is driven to move out of the smoke duct 1; thereby, the stretching degree of the shielding cloth 17 can be adjusted according to the size of the smoke duct 1, so that the shielding cloth 17 can intercept the smoke in the smoke duct 1 to a large extent, and then the intercepted smoke is extracted and detected, so that the flow range of the smoke is more concentrated, and a sufficient amount of smoke can be collected more quickly, thereby shortening the time of the entire detection process and improving the detection efficiency; when the shielding cloth 17 intercepts the smoke, if the impact force of the smoke is too large, it will cause the edge of the shielding cloth 17 to The edge of the shielding cloth 17 is warped and deformed, which causes smoke to flow out from the edge of the shielding cloth 17, and causes the smoke to be more dispersed. Therefore, when the impact force of the smoke is large, the electric push rod 21 is started to drive the pressure plate 1 22 and the pressure plate 2 23 to rise, and with the cooperation of the pressure plate 3 34 and the pressure plate 4 35, the edge of the shielding cloth 17 is clamped, thereby avoiding the situation that when the shielding cloth 17 intercepts the smoke, the edge of the shielding cloth 17 is warped and deformed due to the excessive impact force of the smoke, which causes the smoke to flow out from the edge of the shielding cloth 17, further ensuring the concentration of the smoke and facilitating extraction. In addition, the pressure plates 1 22, 23, 34 and 35 can slide relatively with the stretching of the shielding cloth 17 to ensure that the edge of the shielding cloth 17 can be clamped;Therefore, by using the adjustable covering mechanism, when the smoke in the flue 1 is tested for a short time, the stretching degree of the shielding cloth 17 can be adjusted according to the size of the flue 1, so that the shielding cloth 17 can intercept the smoke in the flue 1 to a large extent, and then the intercepted smoke is extracted for testing, so that the flow range of the smoke is relatively concentrated, and sufficient smoke volume can be collected more quickly, shortening the time of the entire testing process and improving the testing efficiency. In addition, during the testing process, the electric push rod 21 can be started to drive the pressing plate 1 22 and the pressing plate 2 23 to rise, and the edge of the shielding cloth 17 can be clamped with the cooperation of the pressing plate 3 34 and the pressing plate 4 35, so as to avoid the situation that the edge of the shielding cloth 17 is tilted and deformed due to the excessive impact force of the smoke when the shielding cloth 17 intercepts the smoke, causing the smoke to flow out from the edge of the shielding cloth 17, further ensuring the concentration of the smoke and facilitating extraction. ;
