Description

[0002] Flue gas is a mixture of gas and smoke, and its composition is very complex. The pollution to the environment is a compound pollution of multiple poisons. The harm of smoke to the human body is related to the size of the particles. Most of the harm to the human body is caused by floating dust with a diameter of less than 10um, especially 1-2.5um floating dust is the most harmful. Therefore, it is necessary to sample and test the flue gas generated in the production process of enterprises and institutions.

[0003] Most existing flue gas sampling devices use screw caps and other devices to seal the gas collection bottles or bags after sampling. After the sample gas is collected, the impact of ambient temperature on the stability of the flue gas sample is not taken into account. After repeated use, impurities will accumulate inside the sampling component. On the other hand, for the sampling of flue gas with a high concentration of certain harmful particulate matter and greater hazards, if it cannot be observed in advance, the damage to the environment and human body will continue to accumulate, and there is avoidable harm.

[0029] The following will refer to the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0031] Reference Figure 1-4 The utility model provides an embodiment: a flue gas sample retention device, including a body 4, a condenser 15 is installed on the top and bottom of the body 4, a heat conducting baffle 16 is arranged on one side of the condenser 15, a hydraulic rod 17 is fixedly connected to the bottom wall of the heat conducting baffle 16, and a heat sealing machine 20 is fixedly connected to the other end of the hydraulic rod 17, an air duct 2 is threadedly connected to the front end outer wall of the body 4, an exhaust fan 1 is installed on the front end outer wall of the air duct 2, an outer gear ring 11 is rotatably connected inside the rear end outer wall of the air duct 2, a support plate 9 is arranged at the bottom of the front end outer wall of the body 4, a motor 8 is fixedly connected between the top wall of the support plate 9 and the bottom end of the air duct 2, a transmission gear 7 is fixedly connected to the output end of the motor 8, and the transmission gear 7 is meshed with the outer gear ring 11.

[0032] Specifically, the temperature-conducting baffle 16 is fixedly connected to the inner wall of the frame, and the heat sealing machine 20 is divided into two parts, which are respectively fixed on the temperature-conducting baffle 16 at the top and bottom of the body 4. A rotating groove is provided at the outer gear ring 11 at the rear end outer wall of the air duct 2 for normal rotation of the outer gear ring 11, and an opening is provided at the connection of the motor 8 for the transmission gear 7 to mesh with the outer gear ring 11.

[0033] A rotating cover door 19 is rotatably connected to the rear end outer wall of the body 4 , a handle 18 is fixedly installed on the rear end outer wall of the rotating cover door 19 , and a buckle 13 is fixedly connected to the rear end inner wall of the airway 2 .

[0034] Specifically, before the sampling work begins, the rotating cover door 19 is opened by the handle 18, the air collection bag is placed in, and the bag opening is fixed to the buckle 13 on the inner wall of the rear end of the airway 2.

[0035] An observation window 3 is provided on the top wall of the airway 2 , and a plurality of laser emitters 14 are embedded in the inner wall at the right end of the airway 2 .

[0036] Specifically, when the sampling work starts, the laser emitter 14 emits a bright light. When the smoke enters the airway 2, the light emitted by the laser emitter 14 will pass through. Since the smoke is opaque to visible light, the light will change in brightness when the smoke passes through, which can be observed by the naked eye. The darker the light, the greater the concentration of particulate matter in the smoke, that is, the higher the harmfulness.

[0037] A handle 6 is slidably connected to the outer wall of the left end of the airway 2, a filter screen 10 is embedded in the right end of the handle 6, a baffle 5 is fixedly connected to the middle of the handle 6, the right end of the baffle 5 is embedded in the outer wall of the airway 2, and the left end of the baffle 5 is stuck on the outer wall of the left end of the airway 2.

[0038] Specifically, the baffle 5 is used to fix the handle 6 to the outer wall of the airway 2, but is not fixed to the airway 2. The filter 10 can be removed from the handle 6. When the smoke is more harmful, the filter 10 can be taken out in time, and a preliminary and rapid test can be performed on the smoke particulate components thereon so that the staff can quickly make corresponding post-emission treatments.

[0039] A plurality of brush strips 12 are fixedly connected to the inner side of the outer gear ring 11 .

[0040] Specifically, the brush strip 12 can fit the inner wall of the airway 2, and when the motor 8 is started, it follows the rotation of the outer gear ring 11 to scrape and clean the inner wall of the airway 2, thereby ensuring the long-term stable use of the sample retention device.

[0041] Working principle: Before the sampling work starts, the rotating cover door 19 connected to the outer wall of the rear end of the body is opened by the handle 18, the air collection bag is put in, and the bag mouth is fixed to the buckle 13 on the inner wall of the rear end of the airway, and then the rotating cover door 19 is closed, and then the exhaust fan 1 is turned on, and the flue gas enters the flue. First, the light emitted by the laser emitter 14 is observed through the observation window 3. If the light becomes very dark, it means that the concentration of particulate matter in the collected flue gas sample is very high, which is very harmful to the environment and human body. Stop the flue gas emission immediately, and take out the filter 10 on it through the handle 6, and filter the filtered particulate matter on the filter 10. A preliminary analysis is performed so that the staff can quickly make corresponding post-emission treatment; if the light does not change much, it means that the particle concentration of the collected flue gas sample is within a reasonable range, and then the flue gas can be collected normally. After the air collecting bag is filled, the hydraulic rods 17 at the top and bottom ends of the body 4 extend, driving the heat sealer 20 to seal the bag mouth of the air collecting bag efficiently and stably, and due to the working effect of the condenser 15, the air collecting bag and the flue gas samples in the air collecting bag will be at a lower ambient temperature, and the activity of the flue gas samples will be reduced, which ensures the proper preservation of the flue gas samples and reduces the possibility of dangers such as explosions.
