[0015] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0016] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0017] Secondly, the present utility model will be described in detail in conjunction with the schematic diagrams. When detailing the embodiments of the present utility model, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0018] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0019] The specific embodiments are as follows:

[0020] As Figure 1 and Figure 2 shown: A high-altitude waste gas emission device with intelligent adjustment, including: a dust collector 12, a desulfurization and denitrification tower 13. External waste gas first passes through the dust collector 12 and then enters the desulfurization and denitrification tower 13, including: a pressurized high-altitude emission tower 14. The pressurized high-altitude emission tower 14 is connected to the desulfurization and denitrification tower 13. The pressurized high-altitude emission tower 14 includes: an intake unit, an acceleration unit, a remote flue gas concentration monitor 3. The intake unit is connected to the acceleration unit. Waste gas enters from the intake unit and flue gas is discharged from the acceleration unit. The acceleration unit is provided with a remote flue gas concentration monitor 3 and a remote flue gas concentration and wind speed detection controller 7. The remote flue gas concentration monitor 3 can control the speed of the waste gas entering the intake unit, and the remote flue gas concentration monitor 3 can control the amount of external air introduced into the acceleration unit by the acceleration unit. The remote flue gas concentration and wind speed detection controller 7 can control the acceleration amplitude of the waste gas by the acceleration unit.

[0021] Preferably, the intake unit includes an intake box 9, a fan 10, a second intelligent regulating air valve 51, and a second motor 16. The second motor 16 controls the wind speed of the fan 10. Waste gas enters the fan 10 from the second intelligent regulating air valve 51 through the intake box 9. The opening size of the second intelligent regulating air valve 51 can affect the speed of the waste gas entering the intake unit.

[0022] Preferably, the acceleration unit includes: an air collector 1, a three-way flow rear-swing impeller 2, a volute 4, a remote flue gas concentration monitor 3, a first intelligent regulating air valve 5, a wind shield 6, a second motor 16, a rotating shaft 8, a remote flue gas concentration and wind speed detection controller 7, and a first motor 15.

[0023] Preferably, the exhaust gas is discharged from the fan 10 and enters the air collector 1, then is sent into the serrated three-way flow rear-swing impeller 2 for secondary pressurization of the exhaust gas, and then is sent into the volute 4. The remote flue gas concentration monitor 3 in the volute 4 can detect the concentration of the exhaust gas in this space. When the exhaust gas concentration does not meet the standard, it can control the first intelligent regulating air valve 5 to allow external air to enter the volute 4 to dilute the exhaust gas concentration in the volute 4. When the exhaust gas concentration does not meet the standard, it can control the second intelligent regulating air valve 51 to reduce the entry of exhaust gas to avoid more exhaust gas entering the volute 4 and further increasing the exhaust gas concentration. The diluted and up-to-standard exhaust gas is discharged upward through the wind shield 6. A remote flue gas concentration and wind speed detection controller 7 is provided at the top of the wind shield 6. The remote flue gas concentration and wind speed detection controller 7 can detect the exhaust gas concentration and wind speed inside the wind shield 6, and the remote flue gas concentration and wind speed detection controller 7 can detect the atmospheric side wind speed outside the wind shield 6.

[0024] The remote flue gas concentration and wind speed detection controller 7 can control the rotation speed of the serrated three-way flow rear-swing impeller 2 by controlling the second motor 16.

[0025] When the remote flue gas concentration and wind speed detection controller 7 detects that the atmospheric side wind speed outside the wind shield 6 is greater than the exhaust gas wind speed inside the wind shield 6, it will increase the rotation speed of the second motor 16 to increase the rotation speed of the serrated three-way flow rear-swing impeller 2 and further increase the flow rate of the exhaust gas. When the remote flue gas concentration and wind speed detection controller 7 detects that the atmospheric side wind speed outside the wind shield 6 is less than the exhaust gas wind speed inside the wind shield 6, the exhaust gas will not be blown back into the wind shield 6 and can be discharged smoothly.

[0026] When the remote flue gas concentration and wind speed detection controller 7 detects the concentration of the exhaust gas before the exhaust gas is discharged from the wind shield 6, it finally confirms that the discharged exhaust gas meets the standard.

[0027] As Figure 3 shown: The effective smoke column lifting height is the required exhaust gas discharge height he. In order to ensure that the exhaust gas reaching this height will not be blown back into the wind shield 6 and cause exhaust gas backflow, the wind shield outlet speed (fpm) V needs to reach an atmospheric side wind speed (fpm) U not lower than this height.

[0028] The elements in the exhaust gas discharge device are represented as follows:

[0029] Required exhaust gas discharge height: he;

[0030] Fan height: hs;

[0031] Lifting height: hr;

[0032] Velocity at the outlet of the wind hood (fpm): V;

[0033] Velocity of the wind on the atmosphere side (fpm): U;

[0034] Outlet diameter of the wind hood 6 (ft): d;

[0035] he = hs + hr;

[0036] he = (3 × {V × d / U}) + hs;

[0037] Volume of exhaust gas: Qc;

[0038] Volume of introduced dilution air: Qe;

[0039] Total air volume: Qa;

[0040] Qa = Qc + Qs.

[0041] Although the present utility model has been described above with reference to the embodiments, various improvements can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present utility model can be combined with each other in any way, and the exhaustive description of these combinations is omitted in this specification only for the consideration of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
