Technical Field
[0001] The utility model belongs to the technical field of ambient air detection, and in particular relates to an ozone generating and mixing device. Background Art
[0002] Ozone is an allotrope of oxygen, with the chemical formula O3 and a molecular weight of 48.00. It is a light blue gas, dark blue in liquid state, and purple-black in solid state. Its smell is similar to fishy, and when the concentration is too high, it smells like chlorine. Ozone has strong oxidizing properties, such as oxidizing silver into silver peroxide, oxidizing lead sulfide into lead sulfate, and reacting with potassium iodide to generate iodine. Turpentine, coal gas, etc. can spontaneously combust in ozone.
[0003] Ozone is easy to decompose, difficult to store and transport, and the existing technology is generally to produce it on-site. There are three methods to artificially generate ozone: chemical method, ultraviolet method, irradiation method and silent discharge method; silent discharge method is commonly used in water treatment.
[0004] The ozone gas production efficiency of the existing technology is low and it is not easy to preserve. It needs to be produced and used immediately, and it is not sufficient when mixed or reacted with other gases, which easily causes the problem of unstable calibration objects.
[0005] In view of this, the present utility model is proposed. Utility Model Content

[0010] As a preferred embodiment of the present utility model, the first flow limiting hole is fixedly arranged on a side wall of the reaction chamber body, and a first air guide hole in an inclined state is opened on the wall of the reaction chamber body corresponding to the position of the first flow limiting hole, and clean air enters the cavity of the reaction chamber body through the first flow limiting hole and the first air guide hole.
[0011] As a preferred embodiment of the present utility model, the second flow limiting hole is fixedly arranged on the bottom wall of the reaction chamber body close to the gas chamber body, and an L-shaped second air guide hole is commonly opened on the wall surface where the reaction chamber body and the gas chamber body are fixedly connected, and the position of the second air guide hole corresponds to that of the second flow limiting hole.
[0012] As a preferred embodiment of the present utility model, the connecting structure includes an outer liner tube and an inner bore tube. The outer liner tube is fixedly installed on the inner wall of the horizontal end of the second air guide hole, the inner bore tube is located in the cavity of the outer liner tube, one end of the inner bore tube extends into the outer liner tube, and the other end of the inner bore tube is fixedly connected to the wall surface of the reaction chamber body. The inner bore tube connects the air chamber body and the reaction chamber body, and the inner bore tube is also located at the bottom of the cavity of the reaction chamber body.

[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. This solution can be used to detect the performance of molybdenum furnaces in nitrogen oxide analyzers and replace the configuration of a certain concentration of ozone in gas calibrators. It can also be used for other instruments that require ozone as an analysis target. This solution generates ozone gas and reacts with dilution gas or reaction gas as a calibration material for instrument measurement and comparison. This solution solves the problem that ozone gas has low production efficiency and is not easy to store, needs to be generated and used immediately, and is not fully mixed or reacted with other gases, resulting in unstable calibration materials.
[0015] 2. In this scheme, the first air guide hole is inclined toward the ultraviolet lamp, and the cavity of the reaction chamber is a hollow column. When the clean air A enters the cavity of the reaction chamber through the first air guide hole, it can spirally flow and flow away from the bottom of the cavity of the reaction chamber.

The second flow-limiting hole 15 is fixedly arranged on the bottom wall of one side of the reaction chamber body 10 close to the gas chamber body 11, and an L-shaped second air guide hole 18 is opened on the wall surface where the reaction chamber body 10 and the gas chamber body 11 are fixedly connected, and the second air guide hole 18 corresponds to the position of the second flow-limiting hole 15. The connecting structure includes an outer liner tube 16 and an inner bore tube 17. The outer liner tube 16 is fixedly mounted on the inner wall of the horizontal end of the second air guide hole 18. The inner bore tube 17 is located in the cavity of the outer liner tube 16. One end of the inner bore tube 17 extends into the outer liner tube 16.
