[0031] Embodiment one

[0032] As Figures 1-5 shown in the utility model discloses a kind of nitrogen oxide emission purification devices of underground trackless rubber-tyred vehicle, including filter box two 1, frame 7, filter box one 8 and medicine storage box 18,

[0033] The bottom end surface of frame 7 is provided with exhaust pipe 6;

[0034] The inner wall of filter box one 8 is installed with fixed tube 22 by mounting block 27, and the fixed tube 22 is provided with spray head 23;

[0035] The rear end surface of filter box one 8 is installed with medicine storage box 18, and filter box one 8 is gas-communicated with exhaust pipe 6 by sleeve pipe 9;

[0036] Active carbon powder bag 25 is arranged in filter box two 1 by chute plate 24;

[0037] The bottom end surface of filter box one 8 is embedded with liquid collecting tank 4 by drainage pipe 2;

[0038] Pump body 26 is installed in medicine storage box 18, and pump body 26 is liquid-communicated with fixed tube 22 by conveying pipe 21.

[0039] And as those skilled in the art are well known, frame 7 and pump body 26 are provided, and pump body 26 can be powered by external power supply and external control switch, which all belong to conventional means or common knowledge, and will not be described here, and those skilled in the art can select and match as needed or convenient.

[0040] Both ends of filter box one 8 are welded with mounting bracket one 11, and mounting bracket one 11 is connected with frame 7 by bolt one 10, and filter box one 8 can be installed on the bottom end surface of frame 7 by the cooperation of mounting bracket one 11 and bolt one 10.

[0041] Both ends of liquid collecting tank 4 are welded with connecting bracket 5, and one end of connecting bracket 5 away from liquid collecting tank 4 is installed on filter box one 8, and liquid collecting tank 4 can be installed on filter box one 8 by connecting bracket 5.

[0042] The bottom end surface of the liquid collecting tank 4 is embedded with a discharge pipe 3, and a valve is installed on the discharge pipe 3 through a flange plate, and the waste liquid generated by the treatment gas in the liquid collecting tank 4 can be discharged by opening the valve on the discharge pipe 3, and after discharge, the generated waste liquid can be externally connected to a treatment equipment for further filtration or sedimentation treatment.

[0043] The one end of the filter tank 8 away from the sleeve pipe 9 is embedded with a connecting pipe 12, and the one end of the connecting pipe 12 away from the filter tank 8 is embedded in the filter tank 2, and the filter tank 8 and the filter tank 2 can be communicated through the connecting pipe 12.

[0044] The side end surface of the medicine storage tank 18 is embedded with a filling pipe 20, and a sealing cover 19 is installed on the filling pipe 20 through threads, and the liquid denitration agent can be injected into the medicine storage tank 18 through the filling pipe 20 for storage, and after storage, the sealing cover 19 can be rotated to close the filling pipe 20, and the main component of the liquid denitration agent is a complexing agent, a chelating agent and the like.

[0045] Based on example 1: when the staff uses the trackless rubber-tyred vehicle to transport in the underground coal mine, the vehicle discharges the tail gas containing harmful components such as nitrogen oxides through the exhaust pipe 6 equipped on the vehicle frame 7. In order to effectively treat these tail gas, the nitrogen oxides are first introduced into the sleeve pipe 9, and then discharged into the filter tank 8. During the discharge process, the staff can start the pump body 26 in time to extract the liquid denitration agent from the medicine storage tank 18. The denitration agent is injected into the fixed pipe 22 through the conveying pipe 21. Then, the liquid denitration agent is uniformly sprayed through the spray head 23 arranged on the fixed pipe 22, and directly purifies the nitrogen oxides entering the filter tank 8. The waste liquid generated in the purification process is guided to the liquid discharge pipe 2 and finally discharged into the liquid collecting tank 4 for unified collection and management. This measure effectively avoids that the nitrogen oxides in the tail gas of the trackless rubber-tyred vehicle are directly released into the underground working environment without treatment, thereby effectively guaranteeing the air quality of the underground working environment and the health and safety of the workers.

[0046] Example two

[0047] As shown in Figures 1-5 The nitrogen oxide discharge and purification device for underground trackless rubber-tyred vehicle, compared with example one, further comprises: a filter tank 2, a vehicle frame 7, a filter tank 8 and a medicine storage tank 18,

[0048] The bottom end surface of the vehicle frame 7 is provided with an exhaust pipe 6;

[0049] The inner wall of the filter tank 8 is provided with a fixed pipe 22 through an installation block 27, and the fixed pipe 22 is provided with a spray head 23;

[0050] The rear end face of the filter box one 8 is provided with a medicine storage box 18, and the filter box one 8 is in gas communication with the exhaust pipe 6 through the sleeve pipe 9;

[0051] The filter box two 1 is provided with an activated carbon powder bag 25 through the chute plate 24;

[0052] The bottom end face of the filter box one 8 is embedded and fixed with a liquid collecting box 4 through the liquid discharge pipe 2;

[0053] The pump body 26 is installed in the medicine storage box 18, and the pump body 26 is in liquid communication with the fixed pipe 22 through the conveying pipe 21.

[0054] The front and rear ends of the filter box two 1 are both welded with a mounting bracket two 14, and the mounting bracket two 14 is connected with the mounting bracket one 10 through the bolt two 13. The filter box two 1 can be installed at the bottom end face of the vehicle frame 7 through the cooperation of the mounting bracket two 14 and the bolt two 13.

[0055] The bottom end face of the filter box two 1 is provided with a cover plate 17, and the cover plate 17 is connected with the filter box two 1 through the bolt three 16. The cover plate 17 can be installed at the bottom end face of the filter box two 1 through the bolt three 16, so that the bottom end face of the filter box two 1 can be opened and closed through the cover plate 17. Therefore, the activated carbon powder bag 25 in the filter box two 1 can be taken out, replaced and maintained after a long time of use, so as to avoid poor adsorption effect of the activated carbon powder bag 25 after a long time of use.

[0056] The side end face of the filter box two 1 is embedded and fixed with an air outlet pipe 15, and the air outlet pipe 15 is in gas communication with the filter box two 1. The gas treated in the filter box two 1 can be discharged through the air outlet pipe 15.

[0057] Based on example 2: the tail gas discharged by the trackless rubber-tyred vehicle is smoothly introduced into the filter box two 1 through the connecting pipe 12 after being treated and purified by the filter box one 8. In this stage, the gas will be further adsorbed by the activated carbon powder bag 25. The activated carbon powder bag 25 can effectively adsorb the odor components in the tail gas due to its adsorption performance. After being purified by the activated carbon powder bag 25 again, the gas will become more pure, and then be safely discharged through the air outlet pipe 15. This series of processes ensures that the gas generated by the trackless rubber-tyred vehicle during the coal mine transportation in the underground can be comprehensively and effectively filtered, so as to meet the strict requirements of the underground working environment and provide a fresher and safer working atmosphere for the workers.

Any reference signs in the claims should not be construed as limiting the claims concerned.
