Description

Technical Field

[0001] This utility model relates to the field of oxygen preparation technology, and in particular to an oxygen preparation device with multi-stage catalytic decomposition. Background Technology

[0002] Oxygen is an indispensable substance in Earth's life systems, playing a role in many areas such as biological survival, energy metabolism, industrial production, and environmental maintenance. For most organisms, oxygen is a key participant in energy metabolism, directly determining cell survival and the normal functioning of the body. Its core role is concentrated in the process of cellular respiration. Through "aerobic respiration," organisms completely decompose the organic matter in food, releasing a large amount of energy to power activities such as cell division, muscle contraction, and nerve signal transmission. Oxygen's "combustion-supporting property" is the core of its industrial applications. For example, when steelmaking, high-purity oxygen is introduced into the blast furnace to accelerate coke combustion, increase furnace temperature, and at the same time oxidize impurities in pig iron, reducing the carbon content of steel and improving the quality of steel.

[0003] However, most existing oxygen production devices, which are multi-stage catalytic decomposition oxygen production devices, are not very efficient and cannot achieve full catalytic reaction. The oxygen production rate is too slow, the catalytic decomposition efficiency is too slow, and the produced oxygen has a high impurity content, requiring purification. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage catalytic decomposition oxygen preparation device to solve the problems mentioned in the background art. Most of the existing oxygen preparation devices are multi-stage catalytic decomposition oxygen preparation devices, which are inefficient, cannot achieve sufficient catalytic reaction, have a slow oxygen preparation rate, slow catalytic decomposition efficiency, and produce oxygen with high impurity content, requiring purification.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage catalytic decomposition oxygen preparation device, comprising a pressure tank, a catalytic mechanism disposed on the outside of the pressure tank, and a separation mechanism disposed on the outside of the pressure tank;

The centrifugal gas-liquid separator is installed on one side of the heat exchanger. A drain pipe is fixedly installed at the bottom of the centrifugal gas-liquid separator. A water collection tank is installed on one side of the drain pipe. A filter pipe is installed on the upper surface of the centrifugal gas-liquid separator.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a multi-stage catalytic decomposition oxygen preparation device, including a pressure tank 1, a catalytic mechanism 2 disposed on the outside of the pressure tank 1, and a separation mechanism 3 disposed on the outside of the pressure tank 1;

[0022] The catalytic unit 2 includes a delivery pipe 21, a primary reactor 22, a nozzle 23, manganese dioxide particles 24, a secondary reactor 25, metal heat dissipation fins 26, copper oxide particles 27, and a heat exchanger 28. A delivery pipe 21 is installed on one side of the pressure tank 1, and the primary reactor 22 is connected to one side of the delivery pipe 21. A nozzle 23 is installed inside the primary reactor 22, and the interior of the primary reactor 22 is filled with manganese dioxide particles 24. The secondary reactor 25 is connected to one side of the primary reactor 22, and a [missing information - likely a component or material] is fixedly installed on one side of the secondary reactor 25. Metal heat dissipation fins 26; the interior of the secondary reactor 25 is filled with copper oxide particles 27; a heat exchanger 28 is installed on one side of the secondary reactor 25; through the arrangement of the conveying pipe 21, the primary reactor 22, the nozzle 23, the manganese dioxide particles 24, the secondary reactor 25, the metal heat dissipation fins 26, the copper oxide particles 27, and the heat exchanger 28, the high-concentration hydrogen peroxide inside the pressure tank 1 can be converted into oxygen. The high-concentration hydrogen peroxide inside the pressure tank 1 is then transported to the interior of the primary reactor 22 through the conveying pipe 21. The primary reactor 22 is filled with manganese dioxide particles 24. To ensure sufficient contact between the reactants and the manganese dioxide particles 24, a nozzle 23 is placed inside the primary reactor 22. Hydrogen peroxide comes into contact with the manganese dioxide particles 24 inside the primary reactor 22 through the nozzle 23. The hydrogen peroxide first initiates a decomposition reaction inside the primary reactor 22, but only partially decomposes, producing a gas-liquid mixture rich in oxygen and vapor. This mixture is then transported to the secondary reactor 25, which is filled with copper oxide particles 27. The gas-liquid mixture reacts with the copper oxide particles 27, causing the remaining reactants to be almost completely decomposed. The reaction inside the secondary reactor 25 generates a large amount of heat. To dissipate this heat, metal heat sink fins 26 are installed on the outside of the secondary reactor 25, giving it good thermal management. To facilitate the separation of the gas-liquid mixture, the high-temperature gas coming out of the reactor must first be cooled. Therefore, a heat exchanger 28 is connected to one side of the secondary reactor 25 to cool the high-temperature gas.

[0023] Furthermore, the separation mechanism 3 includes a centrifugal gas-liquid separator 31, a drain pipe 32, a water collection tank 33, a filter pipe 34, a microfiltration element 35, a pressure reducing valve 36, and a gas storage tank 37. The centrifugal gas-liquid separator 31 is installed on one side of the heat exchanger 28. A drain pipe 32 is fixedly installed at the bottom of the centrifugal gas-liquid separator 31. A water collection tank 33 is installed on one side of the drain pipe 32. A filter pipe 34 is installed on the upper surface of the centrifugal gas-liquid separator 31. A microfiltration element 35 is fixedly installed inside the filter pipe 34. A pressure reducing valve 36 is installed on one side of the filter pipe 34. A gas storage tank 37 is installed on one side of the pressure reducing valve 36. Through the arrangement of the centrifugal gas-liquid separator 31, drain pipe 32, water collection tank 33, filter pipe 34, microfiltration element 35, pressure reducing valve 36, and gas storage tank 37, the gas is separated and... After filtration and cooling by heat exchanger 28, the gas-liquid mixture enters centrifugal gas-liquid separator 31. Centrifugal gas-liquid separator 31 uses centrifugal force to separate the liquid and gas in the gas-liquid mixture. The separated liquid enters water collection tank 33 through drain pipe 32 installed at the bottom of centrifugal gas-liquid separator 31, thereby collecting the separated liquid. The separated gas enters filter pipe 34, where a microfiltration element 35 is installed. The microfiltration element 35 filters the separated gas for solid particles. The filtered gas enters pressure reducing valve 36 to reduce the pressure of the gas, lowering the high-pressure oxygen produced by the reaction to a safe usable pressure. The depressurized gas is then transported to gas storage tank 37 to complete the storage of oxygen.

[0024] Furthermore, one end of the conveying pipe 21 is connected to the pressure tank 1, and the other end of the conveying pipe 21 is connected to the primary reactor 22. Through the setting of the conveying pipe 21, the high concentration of hydrogen peroxide inside the pressure tank 1 can be conveyed to the primary reactor 22.

[0025] Furthermore, the manganese dioxide particles 24 are evenly distributed inside the primary reactor 22, and the metal heat dissipation fins 26 are evenly distributed on one side surface of the secondary reactor 25. The heat dissipation function of the secondary reactor 25 is enhanced by the arrangement of the metal heat dissipation fins 26, thereby enabling the secondary reactor 25 to have good thermal management function.

[0026] Furthermore, the copper oxide particles 27 are evenly distributed inside the secondary reactor 25. By setting the copper oxide particles 27, the gas-liquid mixture generated inside the primary reactor 22 can be refined to ensure that the raw materials can be completely consumed and the output of qualified products is maximized.

[0027] Furthermore, a centrifugal gas-liquid separator 31 is fixedly connected to one side of the drain pipe 32, and the other side of the drain pipe 32 is connected to the water collection tank 33. The centrifugal gas-liquid separator 31 is used to separate the gas-liquid mixture generated in the reactor.

[0028] Furthermore, the microfilter elements 35 are evenly distributed inside the filter tube 34. Through the arrangement of the microfilter elements 35, catalyst dust and particles entrained in the oxygen can be removed, and solid particles can be filtered from the separated oxygen.

[0029] Working Principle: High-concentration hydrogen peroxide inside the pressure tank 1 is transported to the primary reactor 22 via the delivery pipe 21. The primary reactor 22 is filled with manganese dioxide particles 24. To ensure sufficient contact between the reactants and the manganese dioxide particles 24, a nozzle 23 is placed inside the primary reactor 22. The hydrogen peroxide comes into contact with the manganese dioxide particles 24 through the nozzle 23, initiating a decomposition reaction. However, only partial decomposition occurs, producing a gas-liquid mixture rich in oxygen and vapor. This mixture is then transported to the secondary reactor 25, which is filled with copper oxide particles 27. The gas-liquid mixture reacts with the copper oxide particles 27, resulting in the near-complete decomposition of the remaining reactants. The reaction in the secondary reactor 25 generates significant heat. To dissipate this heat, metal heat sink fins 26 are installed on the exterior of the secondary reactor 25, ensuring good thermal management. To facilitate the separation of the gas-liquid mixture, the high-temperature gas exiting the reactor must first be cooled. Therefore, a heat exchanger 28 is connected to one side of the secondary reactor 25. The heat exchanger 28 performs the cooling function for the high-temperature gas. After being cooled by the heat exchanger 28, the gas-liquid mixture enters the centrifugal gas-liquid separator 31. The centrifugal gas-liquid separator 31 uses centrifugal force to separate the liquid and gas in the gas-liquid mixture. The separated liquid enters the water collection tank 33 through the drain pipe 32 installed at the bottom of the centrifugal gas-liquid separator 31, thereby collecting the separated liquid. The separated gas enters the filter pipe 34, where a microfiltration element 35 is installed. The microfiltration element 35 filters the separated gas for solid particles. The filtered gas enters the pressure reducing valve 36 to reduce the pressure of the gas, lowering the high-pressure oxygen produced by the reaction to a usable safe pressure. The depressurized gas is then transported to the gas storage tank 37 to complete the storage of oxygen.
