[0002] The desulfurization CEMS instrument adopts a direct extraction measurement method. The flue gas is transmitted from the flue to the cabinet of the on-site instrument through a sampling tube heated by a heating belt. The moisture in the flue gas is quickly removed before the flue gas enters the analyzer. The flue gas temperature is cooled to ≤4°C before the analyzer performs the measurement. Finally, the exhaust gas is discharged through the exhaust pipe.

[0003] There are two types of exhaust gas emissions from the desulfurization CEMS instrument, one is discharged indoors and the other is discharged outdoors. When discharged outdoors, the moisture in the exhaust gas will freeze due to the low temperature, and the exhaust pipe will be blocked, causing the analyzer to measure a higher value, and the risk of exceeding the environmental data standard is extremely high. When discharged indoors, the environment between the equipment is polluted, and the SO2 and NOX in the exhaust gas will affect the automatic zero point mark of the analyzer, causing the zero point to be high and the measurement value to be inaccurate.

[0023] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] like Figure 1-Figure 3 As shown, the exhaust gas emission device of the desulfurization CEMS instrument in an embodiment of the present invention includes an air storage box 1 and an exhaust pipe 2. The air storage box 1 has an air inlet and an air outlet. The air inlet is connected to the air outlet end of the desulfurization CEMS instrument. One end of the exhaust pipe 2 is connected to the air outlet, and the other end extends to the outdoors. A heating element 3 is provided in the air storage box 1.

[0025] It can be understood that, since the present application provides an air storage box 1 with a heating element 3 in front of the exhaust pipe 2, the exhaust gas discharged from the desulfurization CEMS instrument can be heated in the air storage box 1 before being discharged to the outside from the exhaust pipe 2. The temperature of the exhaust gas after heating increases and is not easy to freeze, thereby reducing the risk of blockage of the exhaust pipe 2 to prevent environmental protection data from exceeding the standard due to blockage of the exhaust pipe 2. The exhaust gas of the desulfurization CEMS instrument can be discharged to the outside to ensure the normal automatic calibration of the analyzer, and the exhaust pipe 2 will not be affected by the low temperature weather and iced and blocked, thereby ensuring the normal monitoring of the desulfurization CEMS instrument, thereby achieving the purpose of solving the problem and improving the operation stability of the instrument.

[0026] The exhaust gas emission device of the desulfurization CEMS instrument in the embodiment of the present invention has an air storage box 1 with an air inlet and an air outlet, the air inlet is connected to the air outlet end of the desulfurization CEMS instrument, one end of the exhaust pipe 2 is connected to the air outlet, and the other end extends to the outside, and a heating element 3 is provided in the air storage box 1. Therefore, the exhaust gas will first pass through the air storage box 1 and be heated before being discharged to the outside through the exhaust pipe 2, thereby reducing the risk of ice blockage of the exhaust pipe 2 to avoid exceeding the environmental protection data. The exhaust gas of the desulfurization CEMS instrument can be discharged to the outside to ensure the normal automatic calibration of the analyzer, and the normal monitoring of the desulfurization CEMS instrument can be ensured, so as to achieve the purpose of solving the problem and improving the operation stability of the instrument.

[0027] Furthermore, if Figure 1 As shown, the air inlet is arranged on the top plate of the air storage box 1, the connecting end of the exhaust pipe 2 and the air outlet is arranged adjacent to the top plate, and the exhaust pipe 2 extends downwardly in a direction away from the air storage box 1. Therefore, the exhaust pipe 2 arranged downwardly in an inclined manner is conducive to guiding the discharge of the exhaust gas, and if there is ice in the water in the exhaust gas, the exhaust pipe 2 arranged in an inclined manner is also more conducive to the discharge of the liquid in the subsequent cleaning process.

[0028] Optionally, the inclination angle a of the exhaust pipe 2 satisfies 45°≤a≤75°. It should be noted that in specific applications, the inclination angle of the exhaust pipe 2 has certain requirements. When the inclination angle is too large, it is not conducive to guiding the exhaust gas emission. When the inclination angle is too small, the exhaust pipe 2 needs a larger extension length to meet the demand of spanning indoors and outdoors. The inventor of this application found that when the inclination angle a of the exhaust pipe 2 is between 45° and 75°, the exhaust pipe 2 can take into account both the exhaust demand and the rationality of the pipe layout length.

[0029] Preferably, the inclination angle a of the exhaust pipe 2 is 60°.

[0030] In some embodiments, Figure 3 As shown, the air storage box 1 is also provided with an exhaust port, and the exhaust port is provided with an exhaust valve 4. It should be noted that the exhaust port can be set to cope with the situation where emergency exhaust is required. For example, when the heating element 3 fails and the heating fails, the exhaust pipe 2 may be blocked by ice. At this time, the exhaust gas cannot flow out. In this case, the exhaust valve 4 can be opened for emergency exhaust to avoid safety accidents and ensure the safety of the emission device.

[0031] In some embodiments, Figure 3 As shown, the air storage box 1 is also provided with an air hole 5, the diameter of which is smaller than the diameter of the exhaust port. Thus, the air hole 5 can prevent the environmental data from exceeding the standard due to the blockage of the exhaust pipe 2, and the small diameter of the air hole 5 can reduce the pollution of indoor exhaust gas.

[0032] Furthermore, if Figure 2As shown, a heat-conducting frame connected to the heating element 3 is also provided in the air storage box 1, so as to utilize the heat-conducting frame to uniformly heat the exhaust gas in the air storage box 1.

[0033] Furthermore, a condensate discharge pipe is connected to the bottom of the air storage tank 1, and the condensate discharge pipe is used to discharge the condensate caused by the temperature difference in winter.

[0034] In some embodiments, the desulfurization CEMS instrument exhaust gas emission device further includes a controller and a detector, the detector can detect the icing state in the exhaust pipe 2 in real time, and the controller can control the opening and closing of the exhaust valve 4 according to the detection information of the detector. In other words, the icing state in the exhaust pipe 2 can form feedback information, the controller receives the feedback information and controls the action of the valve body, and the whole process does not require manual operation, the response is more timely and manpower can be saved.

[0035] Furthermore, the desulfurization CEMS instrument exhaust gas emission device also includes an alarm device. When the detector detects that the exhaust pipe 2 is frozen, the controller can control the alarm device to send an alarm signal. Therefore, when the exhaust pipe 2 is frozen, the alarm device can send a warning signal to the on-site staff, so that the staff can perform maintenance and repair in time, thereby improving the safety and service life of the equipment.

[0036] For example, the alarm signal may be an indicator light, and the indicator light may be divided into multiple colors according to the degree of icing, so that on-site staff can promptly determine the specific situation in the exhaust pipe 2, provide the best treatment plan, and improve efficiency.

[0037] In other embodiments, the opening and closing of the exhaust valve 4 is not limited to the icing state of the exhaust pipe 2. For example, it can also directly respond to the pressure value in the gas storage tank 1. Specifically, the exhaust gas emission device of the desulfurization CEMS instrument also includes a pressure detector, which is arranged in the gas storage tank 1 to detect the pressure in the gas storage tank 1. The controller can control the exhaust valve 4 to open or close according to the detection value of the pressure detector. It can be understood that when ice blockage occurs in the exhaust pipe 2, the exhaust gas in the gas storage tank 1 cannot be discharged, and the internal pressure will increase. Therefore, the pressure value inside the box can also be used as a basis for judging the icing state of the exhaust pipe 2. When the pressure value reaches the trigger value, it can be judged that an icing problem has occurred. At this time, the exhaust valve 4 can be opened for emergency exhaust.

[0038] In some embodiments, the exhaust pipe 2 is coated with a heat-insulating layer to further prevent the exhaust pipe 2 from freezing.

Therefore, the exhaust gas will first pass through the air storage box 1 and be heated before being discharged to the outside through the exhaust pipe 2, thereby reducing the risk of ice blockage of the exhaust pipe 2 to avoid exceeding the environmental protection data. The exhaust gas of the desulfurization CEMS instrument can be discharged to the outside to ensure the normal automatic calibration of the analyzer, and the normal monitoring of the desulfurization CEMS instrument can be ensured, so as to achieve the purpose of solving the problem and improving the operation stability of the instrument, and the monitoring system has high reliability.
