Description

Technical Field

[0001] This utility model relates to the field of emission collection technology, specifically to an ultra-low emission precision monitoring and collection device. Background Technology

[0002] In the field of emission monitoring technology, accurate monitoring of continuous flue gas emissions is a crucial aspect of environmental protection and pollution control. Traditional flue gas emission monitoring devices are susceptible to various factors during the sampling process, leading to errors in the monitoring data.

[0003] For example, a flue gas emission monitoring device with publication number CN118225515A adopts a sampling method perpendicular to the flue gas flow direction, which can reduce the error caused by flue gas impact or accumulation during the sampling process. This solves the problems of large measurement error and limited sampling location in the existing intercept sampling method. However, flue gas contains a large amount of dust, and the probe is easily blocked by dust during the data collection process, which will lead to significant errors in the collected data. Utility Model Content

[0004] The purpose of this invention is to provide an ultra-low emission precision monitoring and data acquisition device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultra-low emission precision monitoring and data acquisition device, comprising a chimney, a fixed cover fixedly connected to the inner wall of the chimney, two air inlets symmetrically opened on the surface of the fixed cover, a rotating shaft rotatably connected to the center of the fixed cover, a rotating cover fixedly connected to one end of the rotating shaft, two through holes symmetrically opened on the surface of the rotating cover, a fixed cylinder fixedly sleeved on the upper surface of the rotating shaft, and two data acquisition probes symmetrically embedded on the outer wall of the fixed cylinder.

[0006] Preferably, the rotating cover is snapped onto the outer wall of the fixed cover, and the air inlet and through hole are correspondingly arranged.

[0007] Preferably, the orientation of the acquisition probe is set in the same direction as the orientation of the through hole.

[0008] Preferably, a fixing plate is fixedly connected to the outer wall of the chimney, a motor is fixedly connected to the side wall of the fixing plate, a rotating hole is opened on the outer wall of the chimney, the output end of the motor passes through the rotating hole and is fixedly connected to the rotating shaft, and two connecting pipes are symmetrically opened on the outer wall of the chimney, and a connector is fixedly connected to the other end of the connecting pipe.

[0009] Preferably, the connecting pipe corresponds to the space inside the fixing cover.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by setting a rotatable rotating cover, the air inlet and the through hole are connected and disconnected, and the sampling probe is set to face the same direction as the through hole, which can effectively prevent a large amount of dust in the flue gas from directly contacting the sampling probe for a long time, reduce the obstruction of the sampling probe by dust, reduce the probability of significant errors in the collected data due to dust adhesion, and thus improve the accuracy of ultra-low emission monitoring data.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-5 The present invention provides the following technical solution: Example 1: An ultra-low emission precision monitoring and data acquisition device includes a chimney 1, a fixed cover 2 fixedly connected to the inner wall of the chimney 1, two air inlets 3 symmetrically opened on the surface of the fixed cover 2, a rotating shaft 4 rotatably connected to the center of the fixed cover 2, a rotating cover 5 fixedly connected to one end of the rotating shaft 4, two through holes 6 symmetrically opened on the surface of the rotating cover 5, a fixed cylinder 7 fixedly sleeved on the upper surface of the rotating shaft 4, and two data acquisition probes 8 symmetrically embedded on the outer wall of the fixed cylinder 7.

[0015] The rotating cover 5 is snapped onto the outer wall of the fixed cover 2, and the air inlet 3 and the through hole 6 are set accordingly.

[0016] The orientation of the acquisition probe 8 is set in the same direction as that of the through hole 6.

[0017] During use, flue gas flows through the chimney 1. Initially, the air inlet 3 and the through hole 6 are not connected, so the flue gas cannot enter the interior of the fixed cover 2 and will not directly contact the sampling probe 8, thus avoiding a large amount of dust adhering to the sampling probe 8. When flue gas emission monitoring is required, the motor 10 drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 will cause the rotating cover 5 to rotate as well, thereby connecting the air inlet 3 and the through hole 6. At this time, the flue gas can enter the interior of the fixed cover 2 through the air inlet 3 and the through hole 6. Since the orientation of the sampling probe 8 is set in the same direction as the orientation of the through hole 6, the flue gas will not directly impact the sampling probe 8 for a long time when it flows in, but will flow more gently. This greatly reduces the amount of dust adhering to the sampling probe 8, thereby ensuring the accuracy of the collected data. Furthermore, by controlling the intermittent flow of flue gas into the fixed cover 2 through the rotating cover 5, the data collected by the sampling probe 8 can be made closer to the correct value, and the data can be prevented from being affected by anomalies during a single collection.

[0018] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a fixing plate 9 is fixedly connected to the outer wall of the chimney 1, a motor 10 is fixedly connected to the side wall of the fixing plate 9, a rotating hole 11 is opened on the outer wall of the chimney 1, the output end of the motor 10 passes through the rotating hole 11 and is fixedly connected to the rotating shaft 4, and two connecting pipes 12 are symmetrically opened on the outer wall of the chimney 1, and a connector 13 is fixedly connected to the other end of the connecting pipe 12.

[0019] The connecting pipe 12 corresponds to the space inside the fixed cover 2.

[0020] In use, the motor 10 is started, and the output end of the motor 10 drives the rotating shaft 4 to rotate through the rotating hole 11. The rotating shaft 4 drives the rotating cover 5 to rotate, realizing the on / off control of the air inlet 3 and the through hole 6. When the air inlet 3 and the through hole 6 are connected, the flue gas enters the interior of the fixed cover 2. After the acquisition probe 8 collects data, external air or water can be introduced into the interior of the fixed cover 2 through the connecting pipe 12 and the connector 13 to clean the space inside the fixed cover 2 and prevent dust accumulation from invalidating the data collected by the acquisition probe 8. At the same time, according to the actual monitoring needs, the connection time and degree between the air inlet 3 and the through hole 6 can be flexibly adjusted by controlling the forward and reverse rotation and the rotation angle of the motor 10. For example, in some working conditions, continuous monitoring may be required, in which case the air inlet 3 and the through hole 6 can be kept connected for a long time. In other working conditions, only intermittent monitoring may be required, in which case the rotation of the motor 10 can be controlled to achieve intermittent connection between the air inlet 3 and the through hole 6. This flexible control method enables this utility model to adapt to the ultra-low emission monitoring needs under different working conditions.
