Technical Field
[0001] The utility model belongs to the technical field of flue gas purification, and in particular relates to a flue gas emission denitration device. Background Art
[0002] Flue gas denitrification refers to the process of reducing nitrogen oxides in combustion flue gas to nitrogen, thereby removing nitrogen oxides in flue gas. According to the treatment process, it can be divided into wet denitrification and dry denitrification. The importance of preventing environmental pollution has been sharply raised as a global issue. With the development of modern industrial production and the improvement of living standards, air pollution has become a problem of great concern to people. In order to avoid the discharge of nitrogen oxides into the atmosphere and cause environmental pollution, flue gas denitrification is particularly important.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a flue gas emission denitrification device.
[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0028] like Figures 1 to 4 As shown, a flue gas emission denitration device in one embodiment of the utility model includes: a flue gas denitration cylinder 1, an air intake separation mechanism 2 and a purification mechanism 3.
[0029] like Figure 1 As shown, a support partition 101 is fixed inside the flue gas denitrification cylinder 1, which is used to support the rotary motor 301, so that the rotary motor 301 is not easy to shake or tilt, thereby improving the stability of the rotary motor 301. A plurality of evenly distributed air holes 102 are drilled on the support partition 101 for the flow of gas, so that the gas can only be purified by the activated carbon filter 103 if it wants to be discharged, thereby improving the purification effect of the flue gas. The rotary motor 301 is installed in the support partition 101.
[0030] Specifically, an activated carbon filter 103 is arranged above the supporting partition 101 to improve the purification effect of the flue gas, so that the discharged flue gas is less likely to contain harmful substances, and thus less likely to cause a bad impact on the environment. The top of the flue gas denitrification cylinder 1 is also provided with a plurality of evenly distributed exhaust holes 104 for discharging the purified flue gas to avoid the accumulation of the flue gas, so as not to affect the subsequent purification of the flue gas.
[0031] like Figures 1 to 4As shown, the air intake separation mechanism 2 is installed on the flue gas denitration cylinder 1, and the air intake separation mechanism 2 includes a separation box 201, which provides space for filtering impurities in the flue gas, and a separation screen 202 is fixed in the separation box 201, which is used to screen out impurities in the flue gas, so that the impurities are not easy to enter the ammonia water in the flue gas denitration cylinder 1. The separation screen 202 is tilted, and an air intake pipe 203 is fixedly connected to the separation box 201, and a support frame 204 is fixed below the separation box 201.
[0032] Specifically, a collecting frame 205 is inserted into the support frame 204 for collecting the screened impurities, and a sealing rubber ring is provided between the support frame 204 and the collecting frame 205 to improve the sealing performance of the device so that the smoke is not prone to leakage.
[0033] In addition, a lower leakage hole 206 is drilled at the bottom of the separation box 201 to allow the screened impurities to fall into the collection frame 205, so as to collect the impurities and facilitate cleaning by the staff. A handle 207 is fixed on the collection frame 205 to pull the collection frame 205, thereby facilitating the staff to clean up the impurities.
[0034] like Figure 1 As shown, one side of the separation box 201 is also connected to a delivery air pipe 208, and the other end of the delivery air pipe 208 is inserted into the flue gas denitration cylinder 1 for delivering flue gas so that the flue gas can enter the dispersion frame 209. The dispersion frame 209 is provided in the flue gas denitration cylinder 1. One end of the delivery air pipe 208 away from the separation box 201 is connected to the dispersion frame 209, and a plurality of one-way exhaust valves 211 are installed on the dispersion frame 209 for ejecting the flue gas and preventing the ammonia water from flowing back, thereby improving the stability of the device.
[0035] like Figure 1 As shown, a plurality of fixing columns 210 are fixedly connected between the dispersion frame 209 and the inner wall of the flue gas denitrification cylinder 1, which are used to fix the dispersion frame 209, so that the dispersion frame 209 is not prone to shaking or tilting, thereby improving the stability of the device and further improving the injection stability of the flue gas.
[0036] like Figures 1 to 4 As shown, the purification mechanism 3 is installed on the flue gas denitration tube 1, and the purification mechanism 3 includes a rotating motor 301, which is used to drive the rotating support shaft 302 and the spoiler 303 to rotate and provide power to provide conditions for turbulence. The rotating motor 301 is arranged in the flue gas denitration tube 1. The rotating motor 301 is fixedly connected to the rotating support shaft 302, and a plurality of spoilers 303 are fixed on the rotating support shaft 302, which are used to disturb the flue gas so that the flue gas is fully in contact with the sprayed ammonia water, thereby improving the purification effect of the flue gas.
[0037] Specifically, a liquid delivery pipe 305 is provided on one side of the rotating support shaft 302, and a nozzle 306 is fixedly installed on one end of the liquid delivery pipe 305 disposed in the flue gas denitration cylinder 1, for spraying ammonia water.

[0039] When in use, the flue gas is introduced into the separation box 201 through the air inlet pipe 203, and then the impurities in the flue gas are screened out through the separation screen 202, and the screened impurities will slide into the collection frame 205, which is convenient for the staff to take out, and the flue gas will be transported to the dispersion frame 209 through the delivery air pipe 208, and finally ejected through multiple one-way exhaust valves 211, and the ejected flue gas will directly contact the ammonia water in the flue gas denitrification cylinder 1, so that the flue gas is fully purified;
[0040] Moreover, the flue gas will float upward, and after the liquid pump 304 is started, the ammonia water will be extracted through the liquid extraction pipe 308, and then transported through the liquid delivery pipe 305 and sprayed by the nozzle 306, so that the flue gas floating upward will be fully in contact with the ammonia water again, achieving the effect of double purification treatment, and the start-up of the rotating motor 301 will drive the rotating support shaft 302 and the spoiler 303 to rotate, thereby improving the full contact between the ammonia water and the flue gas, improving the purification effect of the flue gas, and finally being discharged through the exhaust hole 104 after adsorption and purification by the activated carbon filter element 103.
