[0018] Embodiment
[0019] Such as Figure 1 、 2As shown, in this embodiment, a flue gas sampling buffer device is mainly disclosed. It is simple and compact in structure, including a tank body 1. An air inlet pipe 2 is provided above the side wall of the tank body 1. The top end of the tank body 1 is hermetically connected to an air outlet pipe 3. One end of the air outlet pipe 3 extends into the interior of the tank body 1, and the inner end of the air outlet pipe 3 inside the tank body 1 is a spiral rising flue 30. The bottom of the tank body 1 is a sealed sphere. It should be noted that the tank body 1 is a sealed hollow structure. The flue gas to be sampled is introduced into the interior of the tank body 1 through a pipeline via the air inlet pipe 2. The particulate impurities contained in the flue gas fall to the bottom inside the tank body 1 under the action of gravity and centrifugal force. The flue gas stays inside the tank body 1, and the moisture in the flue gas gradually condenses and accumulates at the bottom of the tank body 1. The internal flue 30 at the end of the air outlet pipe 3 extending into the tank body 1 spirally rises, which helps the moisture to condense and fall. The bottom of the tank body 1 is designed as a sphere, which is convenient for the flue gas to flow back, effectively separating the moisture and particulate impurities in the flue gas, ensuring that the representativeness of the elements in the sampled flue gas is not affected, and guaranteeing the representativeness and accuracy of the sampling. In addition, after the flue gas sampling is completed, the buffer device needs to be cleaned. It can be disassembled, the tank body 1 is turned over, the condensed water and particulate impurities collected inside the tank body 1 are poured out from the air inlet pipe 2 and then cleaned and dried in an oven for the next use.
[0020] Further, in specific implementation, at the pipe orifices of the above-mentioned air inlet pipe 2 and air outlet pipe 3 provided in the embodiment of the present utility model, there are end heads 4 for sleeving flexible hoses. A ring groove 40 is provided on the outer wall of the end head 4. Specifically, the end head 4 is a hollow frustum shape, and the outermost end is a small-diameter section, which is convenient for sleeving the flexible hose. The ring groove 40 can further connect a ferrule to tightly sleeve the flexible hose, ensuring the firm connection between the flexible hose and the air inlet pipe 2 and the air outlet pipe 3 and preventing the flue gas from leaking.
[0021] Further, in specific implementation, at the position one-third above the interior of the tank body 1 where the above-mentioned air outlet pipe 3 extends into the tank body 1, it is ensured that the condensed water and particulate impurities will not be discharged from the air outlet pipe 3 along with the air flow.
[0022] Further, in specific implementation, the above-mentioned tank body 1, air inlet pipe 2, and air outlet pipe 3 are all made of transparent glass material, which is convenient for the operator to clearly observe the internal conditions, facilitating the monitoring of the real-time conditions and the timely handling of abnormal situations.
[0023] Further, in specific implementation, the above-mentioned air inlet pipe 2 and the tank body 1 are integrally formed, and the air outlet pipe 3 and the tank body 1 are hermetically welded, which helps to reduce the risk of flue gas leakage and ensure the stability of the sampling environment.
[0024] Further, in specific implementation, the air inlet pipe orifice of the above-mentioned air inlet pipe 2 and the air outlet pipe orifice of the air outlet pipe 3 are arranged opposite to each other, which helps the flue gas to flow in and out smoothly and improves the sampling efficiency.
[0025] Furthermore, in specific implementation, a vacuum pump is connected to the above-mentioned air outlet pipe 3 provided in the embodiment of the present invention. A certain negative pressure is formed inside the tank body 1 through the vacuum pump, and the flue gas is filtered and adsorbed on the sampling cotton from the inside of the tank body 1 to ensure the reliability of sampling.
[0026] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
