Technical Field
[0001] The utility model relates to the technical field of teaching experiments, in particular to an oxygen-nitrogen reaction device. Background Art
[0002] The reaction between nitrogen and oxygen at high temperature or discharge conditions, that is, under discharge conditions, nitrogen can combine with oxygen to form nitric oxide. When students conduct this part of the experiment, they need an oxygen-nitrogen reaction test device to conduct a discharge test.
[0003] However, after the reaction, nitric oxide and nitrogen dioxide are likely to remain inside the device. Both nitric oxide and nitrogen dioxide produced after the reaction are toxic and can easily escape and cause harm to students and teachers, making it inconvenient to use. Utility Model Content
[0004] Based on this, the purpose of the present invention is to provide an oxygen-nitrogen reaction device to solve the technical problems mentioned in the above background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an oxygen-nitrogen reaction device, comprising a suction filtration bottle, a distribution pipe connected to the inside of the suction filtration bottle, and an insulating sleeve connected to the outside of the distribution pipe, an insulating sleeve connected to the outside of the insulating sleeve, and a nozzle opened at the bottom of the distribution pipe.
[0006] By adopting the above technical solution, fresh air can be distributed to multiple nozzles through the distribution pipe, and then the multiple nozzles blow air downwardly at an angle toward the bottom of the suction bottle, so that the interior of the suction bottle is filled with fresh air, and nitric oxide and nitrogen dioxide are discharged from the gas storage tank into the gas sensor and the liquid storage cup, thereby avoiding residual nitric oxide and nitrogen dioxide in the suction bottle and causing students or teachers to inhale them during subsequent cleaning. In addition, the heat released during the reaction of oxygen and nitrogen is reduced by the insulation sleeve to reduce the impact of the heat released during the reaction of oxygen and nitrogen on the distribution pipe, and the provision of the insulation sleeve prevents the electric spark generated by the spark generator from breaking through the insulation sleeve and the distribution pipe, thereby improving safety.
[0007] Furthermore, the insulating sleeve is made of ceramic material.
[0008] By adopting the above technical solution, the heat released during the reaction of oxygen and nitrogen is reduced by the heat insulation sleeve to reduce the impact on the distribution pipe, and the provision of the insulating sleeve prevents the electric spark generated by the spark generator from piercing the heat insulation sleeve and the distribution pipe, thereby improving safety.
[0009] Furthermore, the nozzle is tilted, and the tilt angle of the nozzle is °.
[0010] By adopting the above technical solution, the nozzle blows fresh air downward, thereby displacing the nitric oxide and nitrogen dioxide in the suction bottle upward, avoiding the residual nitric oxide and nitrogen dioxide in the suction bottle.
[0011] Furthermore, the nozzles are provided in plurality and are distributed in a ring array and divided into two groups, and the two groups of nozzles are respectively located in the inner circle and the outer circle of the distribution pipe.
[0012] By adopting the above technical solution, the number of nozzles is increased, thereby increasing the purge area and reducing the purge dead angle, thereby facilitating the upward extrusion of nitric oxide and nitrogen dioxide in the suction filtration bottle.
[0013] Furthermore, an air inlet is provided on one side of the suction bottle, a bottle stopper is connected to the top of the suction bottle, and an air outlet pipe and an electric spark generator are respectively passed through the top of the bottle stopper, one end of the air outlet pipe is connected to a gas sensor, one side of the gas sensor is connected to an injection pipe, and a liquid storage cup is provided on one side of the suction bottle.
[0014] By adopting the above technical solution, after the external air pump is started, air is injected into the suction bottle through the distribution pipe and the nozzle. After the electric spark generator is started, the air is placed in a discharge environment. Then, part of the nitrogen in the air reacts with oxygen to generate nitric oxide, and at the same time, part of the nitric oxide continues to react with the air to generate nitrogen dioxide. Then, the nitric oxide, nitrogen dioxide and air enter the gas sensor through the outlet pipe to be detected for the concentration of each group of gases. At the same time, the gas sensor converts the concentration of nitric oxide, nitrogen dioxide and air into electrical signals and transmits them to the computer for students to view. After detection, the nitric oxide, nitrogen dioxide and air pass through the longer injection pipe into the sodium hydroxide solution in the storage cup. Since the injection pipe is long, the residual nitric oxide has enough time to react with oxygen to generate nitrogen dioxide, thereby avoiding the phenomenon that the nitric oxide cannot react with the sodium hydroxide solution and reacts with oxygen after being discharged to pollute the environment. Then, the nitrogen dioxide reacts with the sodium hydroxide solution to generate sodium nitrate crystals, sodium nitrite crystals and water.
[0015] Furthermore, a first bracket is placed at the lower part of the liquid storage cup, and a first baffle is fixed on the top of the first bracket, and a second baffle is fixed on the top of the first baffle via a second bracket.
[0016] By adopting the above technical solution, the first baffle and the second baffle are supported by the first bracket and the second bracket, and the first bracket, the second bracket, the first baffle and the second baffle cooperate to form a maze, thereby extending the residence time of nitrogen dioxide in the sodium hydroxide solution, so that the sodium hydroxide solution can fully react with the nitrogen dioxide to generate sodium nitrate crystals, sodium nitrite crystals and water.
[0017] Furthermore, two of each of the first baffles and the second baffles are provided, and the two first baffles and the two second baffles are staggered.
[0018] By adopting the above technical solution, the first bracket, the second bracket, the first baffle and the second baffle cooperate to form a maze, thereby extending the residence time of nitrogen dioxide in the sodium hydroxide solution and allowing the sodium hydroxide solution to fully react with the nitrogen dioxide.
[0019] Furthermore, the first bracket and the second bracket are both provided in plurality, and the first bracket and the second bracket are distributed vertically.
[0020] By adopting the above technical solution, the first baffle and the second baffle are supported by the first bracket and the second bracket, and the vertical distribution of the two can extend the residence time of nitrogen dioxide.
[0021] In summary, the present invention has the following beneficial effects:

The distribution pipe can distribute fresh air to multiple nozzles, and then the multiple nozzles blow air downwardly at an angle toward the bottom of the suction bottle, so that the interior of the suction bottle is filled with fresh air, while nitric oxide and nitrogen dioxide are discharged from the gas storage tank into the gas sensor and the liquid storage cup, thereby preventing nitric oxide and nitrogen dioxide from remaining in the suction bottle and causing students or teachers to inhale them during subsequent cleaning. The heat-insulating sleeve reduces the effect of heat released during the reaction of oxygen and nitrogen on the distribution pipe, and the provision of the insulating sleeve prevents sparks generated by the spark generator from piercing the heat-insulating sleeve and the distribution pipe, thereby improving safety and effectively preventing gas residue.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0030] The following describes an embodiment of the present invention based on its overall structure.
[0031] Example 1:
[0032] An oxygen-nitrogen reaction device, such as Figure 1-Figure 3 As shown, it includes a suction bottle 1, which is internally connected to a distribution pipe 7. The distribution pipe 7 is a stainless steel hose, which is convenient for disassembly and cleaning; the distribution pipe 7 is externally sleeved with a heat-insulating sleeve 8, which reduces the effect of the heat released during the reaction of oxygen and nitrogen on the distribution pipe 7; the heat-insulating sleeve 8 is externally sleeved with an insulating sleeve 9, which is made of ceramic material. The setting of the insulating sleeve 9 prevents the electric spark generated by the spark generator 6 from piercing the insulating sleeve 8 and the distribution pipe 7; a nozzle 10 is provided at the bottom of the distribution pipe 7, and the nozzle 10 is tilted. The tilt angle of the nozzle 10 The angle of the nozzles 10 is 45°, and a plurality of nozzles 10 are provided. The plurality of nozzles 10 are distributed in a circular array and are divided into two groups. The two groups of nozzles 10 are respectively located in the inner circle and the outer circle of the distribution pipe 7. The fresh air can be distributed to the plurality of nozzles 10 through the distribution pipe 7. Then the plurality of nozzles 10 are tilted downward to blow air toward the bottom of the suction bottle 1, so that the interior of the suction bottle 1 is filled with fresh air, and nitric oxide and nitrogen dioxide are discharged from the gas storage tank into the gas sensor 5 and the liquid storage cup 11, so as to avoid nitric oxide and nitrogen dioxide remaining in the suction bottle 1 and causing inhalation by students or teachers during subsequent cleaning.
[0033] See Figure 1 and Figure 2In the above embodiment, an air inlet 2 is provided on one side of the suction bottle 1, and air is injected into the suction bottle 1 after the external air pump is started; a bottle stopper 3 is connected to the top of the suction bottle 1 to prevent air leakage; an air outlet pipe 4 and an electric spark generator 6 are respectively passed through the top of the bottle stopper 3. After the electric spark generator 6 is started, the air is placed in a discharge environment, and then part of the nitrogen in the air reacts with oxygen to produce nitric oxide, and at the same time, part of the nitric oxide continues to react with the air to produce nitrogen dioxide; a gas sensor 5 is connected to one end of the air outlet pipe 4, and nitric oxide, nitrogen dioxide and air enter the gas sensor 5 through the air outlet pipe 4 to detect the gas concentration of each group, and at the same time, the gas sensor 5 The concentrations of nitric oxide, nitrogen dioxide and air are converted into electrical signals and transmitted to a computer for students to view; an injection tube 12 is connected to one side of the gas sensor 5, and a liquid storage cup 11 is provided on one side of the suction filtration bottle 1. The detected nitric oxide, nitrogen dioxide and air pass through the longer injection tube 12 and enter the sodium hydroxide solution in the liquid storage cup 11. Since the injection tube 12 is longer, the residual nitric oxide has enough time to react with oxygen to generate nitrogen dioxide, thereby avoiding the phenomenon that nitric oxide cannot react with the sodium hydroxide solution and then reacts with oxygen after being discharged to pollute the environment. Afterwards, the nitrogen dioxide reacts with the sodium hydroxide solution to generate sodium nitrate crystals, sodium nitrite crystals and water.
[0034] Example 2:
[0035] On the basis of the above embodiment 1, in order to prevent nitrogen dioxide from escaping, the following settings are now adopted.
[0036] See Figure 1 、 Figure 2 and Figure 4 In the above embodiment, a first bracket 13 is placed at the bottom of the liquid storage cup 11, a first baffle 15 is fixed on the top of the first bracket 13, and a second baffle 16 is fixed on the top of the first baffle 15 through the second bracket 14. There are two first baffles 15 and two second baffles 16, and the two first baffles 15 are staggered with the two second baffles 16. There are multiple first brackets 13 and second brackets 14, and the first bracket 13 and the second bracket 14 are vertically spaced. The first bracket 13, the second bracket 14, the first baffle 15 and the second baffle 16 cooperate to form a maze, thereby extending the residence time of nitrogen dioxide in the sodium hydroxide solution and allowing the sodium hydroxide solution to fully react with the nitrogen dioxide.
[0037] The implementation principle of the present utility model is as follows: first, the operator places the spark generator 6 at the bottom of the bottle stopper 3. Since the distribution tube 7 is a stainless steel hose, the operator places the distribution tube 7 with the surface covered with a heat insulation sleeve 8 and an insulating sleeve 9 into the suction bottle 1, and passes one end of the distribution tube 7 through the air inlet 2. Then, the operator connects one end of the distribution tube 7 to the air outlet end of the external air pump. Then, the operator places the bottle stopper 3 into the cleaned suction bottle 1 and pours sodium hydroxide solution into the liquid storage cup 11. Then, the operator places the gas sensor 5 with the air outlet pipe 4 and the injection pipe 12 connected at both ends respectively between the suction bottle 1 and the liquid storage cup 11, and the air outlet pipe 4 passes through the bottle stopper 3 to enter the upper part of the interior of the suction bottle 1, and the injection pipe 12 passes through the inner circle of the first baffle 15 and the second baffle 16 to enter the lower part of the interior of the liquid storage cup 11;
[0038] After the external air pump is started, air is injected into the suction filtration bottle 1 through the distribution pipe 7 and the nozzle 10. After the electric spark generator 6 is started, the air is placed in a discharge environment. Then, part of the nitrogen in the air reacts with oxygen to generate nitric oxide. At the same time, part of the nitric oxide continues to react with the air to generate nitrogen dioxide. Then, the nitric oxide, nitrogen dioxide and air enter the gas sensor 5 through the outlet pipe 4 to be detected for the concentration of each gas group. At the same time, the gas sensor 5 converts the concentration of nitric oxide, nitrogen dioxide and air into electrical signals and transmits them to the computer for students to view. The heat insulation sleeve 8 is used to reduce the influence of the heat released during the reaction of oxygen and nitrogen on the distribution pipe 7. The provision of the insulating sleeve 9 prevents the electric spark generated by the electric spark generator 6 from breaking through the heat insulation sleeve 8 and the distribution pipe 7, thereby improving safety.
[0039] After detection, the nitric oxide, nitrogen dioxide, and air pass through the longer injection tube 12 and enter the sodium hydroxide solution in the liquid storage cup 11. Since the injection tube 12 is longer, the residual nitric oxide has sufficient time to react with oxygen to generate nitrogen dioxide, thereby preventing the nitric oxide from being unable to react with the sodium hydroxide solution and reacting with oxygen after being discharged to pollute the environment. Thereafter, the nitrogen dioxide reacts with the sodium hydroxide solution to generate sodium nitrate crystals, sodium nitrite crystals, and water. The first baffle 15 and the second baffle 16 are supported by the first bracket 13 and the second bracket 14, and the first bracket 13, the second bracket 14, the first baffle 15, and the second baffle 16 cooperate to form a maze, thereby extending the residence time of the nitrogen dioxide in the sodium hydroxide solution, so that the sodium hydroxide solution can fully react with the nitrogen dioxide to generate sodium nitrate crystals, sodium nitrite crystals, and water.
[0040] After the test, the electric spark generator 6 stops working, and fresh air can be distributed to multiple nozzles 10 through the distribution pipe 7. Then, the multiple nozzles 10 tilt downward to blow air toward the bottom of the suction bottle 1, so that the interior of the suction bottle 1 is filled with fresh air, and nitric oxide and nitrogen dioxide are discharged from the gas storage tank into the gas sensor 5 and the liquid storage cup 11, avoiding the residual nitric oxide and nitrogen dioxide in the suction bottle 1 and causing students or teachers to inhale them during subsequent cleaning.

The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
