Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and more specifically, relates to a waste gas treatment device for purifying nitrogen oxides. Background Art

[0002] Nitrogen oxides refer to compounds composed solely of nitrogen and oxygen. Common nitrogen oxides include nitric oxide, nitrogen dioxide, dinitrogen monoxide, and dinitrogen pentoxide. With the exception of dinitrogen pentoxide, which is a solid under normal conditions, all other nitrogen oxides are gaseous. Nitrogen oxides, as air pollutants, often refer to nitric oxide and nitrogen dioxide. Nitrogen oxides react with oxygen and water (H2O) in the air to produce acid rain. Under photochemical conditions, they produce photochemical smog, which affects visibility. Nitrogen oxide waste gas can be treated through catalytic reduction, adsorption, and absorption methods.

[0003] Application No. CN202322351123.7 The utility model discloses a nitrogen oxides waste gas treatment device, comprising a box body, wherein the box body is fixedly mounted with a motor, the box body is rotatably connected with a screw rod, the screw rod is threadably connected to a mounting block, the box body is fixedly connected with a symmetrically arranged guide rod, both sides of the mounting block are fixedly connected with a support rod, the support rods are fixedly connected with a plurality of bearings, the bearings are fixedly connected with symmetrically arranged stirring blades, a connecting block is fixedly connected between the stirring blades, and a plurality of striking rods arranged up and down are fixedly connected to the inner wall of the box body, the top of the box body is fixedly connected with a plurality of nozzles, the tops of the nozzles are commonly fixedly connected with a liquid collecting pan, and the liquid collecting pan is fixedly connected with a liquid inlet. The beneficial effects of the utility model are that the waste gas can be driven to flow, so that the dissolving liquid can fully dissolve and dilute the waste gas, the treatment efficiency is high, and the quality of waste gas treatment is also very good.

[0004] Based on the search of the above patents and the application of existing waste gas treatment devices for purifying nitrogen oxides, it is understood that most of the waste gas of nitrogen oxides needs to be transported through pipelines before being treated. However, when the transportation is stopped, some of the waste gas of nitrogen oxides is prone to backflow. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an exhaust gas treatment device for purifying nitrogen oxides, so as to solve the problem that most of the existing nitrogen oxide exhaust gases need to be transported through pipelines before being treated, but when the transportation is stopped, some of the nitrogen oxide exhaust gases are prone to backflow.

[0006] The technical solution adopted by this utility model is:

[0007] A waste gas treatment device for purifying nitrogen oxides includes a waste gas delivery pipe; an installation frame is provided at an internal position of the waste gas delivery pipe, a mounting ring is provided at an internal front end position of the installation frame, the front end position of the mounting ring is fixedly connected to the rear end of a spring member, the internal front end position of the installation frame is conical in design, the front end position of the spring member is provided with a conical plug, the conical plug is located at the internal front end position of the installation frame, and when the spring member is in an extended state, the front end position of the conical plug is aligned with the internal front end position of the installation frame.

[0012] According to one embodiment of the present invention, an exhaust fan is provided at the rear end of the mounting frame, and the exhaust fan is located directly behind the conical plug.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples.

[0025] Example 1:

[0026] As attached Figure 1To the attached Figure 4 As shown:

[0027] The utility model provides an exhaust gas treatment device for purifying nitrogen oxides, comprising an exhaust gas delivery pipe 1; an additional frame 104 is provided at an internal position of the exhaust gas delivery pipe 1, a mounting ring 105 is provided at an internal front end position of the mounting frame 104, the front end position of the mounting ring 105 is fixedly connected to the rear end of a spring member 106, the internal front end position of the mounting frame 104 is a conical design, the front end position of the spring member 106 is provided with a conical plug 107, the conical plug 107 is located at the internal front end position of the mounting frame 104, and when the spring member 106 is in an extended state, the front end position of the conical plug 107 is fixedly connected to the rear end of the mounting ring 105. The front end position inside the mounting rack 104 fits together, the front and rear ends of the exhaust gas conveying pipe 1 are designed to be through-through, and an inspection plate 103 is fixedly installed at the front and rear ends of the exhaust gas conveying pipe 1 respectively. The top front end position of the exhaust gas conveying pipe 1 is fixedly connected with the input pipe 101, and the top rear end position of the exhaust gas conveying pipe 1 is fixedly connected with the output pipe 102. The output pipe 102 and the input pipe 101 are symmetrically distributed at the top position of the exhaust gas conveying pipe 1. When inspecting the inside of the exhaust gas conveying pipe 1, the inspection plate 103 is removed, and the parts installed inside the mounting rack 104 can be disassembled, maintained and replaced.

[0028] Among them, the top position of the output pipe 102 is fixedly connected to the middle position of the bottom of the processing tank 2, and the interior of the processing tank 2 is designed to be connected to the interior of the output pipe 102. The middle position of the top of the processing tank 2 is fixedly connected to the bottom position of the transmission pipe 201. The transmission pipe 201 is located directly above the output pipe 102. An exhaust fan 108 is provided at the rear end position of the interior of the mounting frame 104, and the exhaust fan 108 is located directly behind the conical plug 107.

[0029] When using:

[0030] The waste gas conveying pipe 1 is installed and fixed in an underground position, and then the waste gas conveying pipe 1 is pre-buried. In this way, when the treatment tank 2 is used, the pipeline is avoided from being set in the open air to cause interference and the waste gas conveying pipe 1 is increased to avoid collision with foreign objects.

[0031] Connect the input pipe 101 to the exhaust gas conveying pipe to transmit the exhaust gas to the inside of the exhaust gas conveying pipe 1. During this period, start the exhaust fan 108. The wind generated by the exhaust fan 108 is transmitted to the rear position. The adsorption force generated by the exhaust fan 108 will pull the conical plug 107 to slide backward inside the mounting frame 104, so that the front end position of the conical plug 107 is separated from the fit with the front end position inside the mounting frame 104. The exhaust fan 108 can speed up the rapid circulation of the exhaust gas inside the exhaust gas conveying pipe 1 and transfer it to the inside of the treatment tank 2 through the output pipe 102 for exhaust gas treatment.

[0032] When the exhaust fan 108 stops, the spring member 106 will not be subjected to the extrusion force generated by the conical plug 107 and the exhaust fan 108. The spring member 106 drives the conical plug 107 to perform a reset operation, and the front end position of the conical plug 107 is in contact with the front end position inside the mounting frame 104 to prevent the exhaust gas from flowing back inside the exhaust gas conveying pipe 1.

[0033] Although the present application has been described with reference to the above embodiments, it will be understood by those skilled in the art that various changes may be made without departing from the concept and scope of the present application as defined in the appended claims. Although this specification contains many specific implementation details, these should not be interpreted as limitations on the scope of protection claimed in this application, but rather as descriptions of features specific to specific embodiments. The scope of this application is defined by the appended claims and their equivalents, and is not limited to the embodiments described above.
