DETAILED DESCRIPTION

[0020] The utility model is further illustrated below in combination with the drawings and examples.

[0021] In the existing found implementable technology, "CO" usually refers to carbon monoxide in chemistry.

[0022] Basic properties

[0023] Physical properties

[0024] Carbon monoxide is a colorless, odorless, and odorless gas. This makes it difficult for people to detect when it leaks, which has a certain risk.

[0025] Its density is slightly smaller than that of air. Under standard conditions (0℃, 1 standard atmosphere), the density of carbon monoxide is 1.250g / L, and the density of air is about 1.293g / L.

[0026] Carbon monoxide is difficult to dissolve in water. Under normal temperature and pressure, 1 volume of water can only dissolve about 0.02 volume of carbon monoxide.

[0027] Chemical properties

[0028] Combustibility: Carbon monoxide can burn, and the chemical equation is ignited. When burning, it will produce a blue flame and release a large amount of heat. It is one of the components of many gas fuels, such as water gas, whose main components are carbon monoxide and hydrogen.

[0029] Reducing property: Carbon monoxide is an important reducing agent. It can reduce metal oxides, such as reacting with copper oxide, and the chemical equation is as follows. In this reaction, carbon monoxide reduces the copper ions in copper oxide to copper single element, and itself is oxidized to carbon dioxide. This property makes carbon monoxide used in the smelting industry to extract metals from ores.

[0030] Toxicity: Carbon monoxide is highly toxic. It can bind to hemoglobin (Hb) in human blood, and its binding capacity is 200-300 times stronger than that of oxygen. Once carbon monoxide binds to hemoglobin, it forms carboxyhemoglobin (HbCO), which makes hemoglobin lose its ability to transport oxygen, leading to tissue and organ hypoxia in the human body. When the concentration of carbon monoxide in the air reaches a certain level, people will show symptoms of poisoning, such as headache, dizziness, nausea, vomiting, etc., and in severe cases, can cause death.

[0031] Source

[0032] Incomplete combustion: This is one of the main sources of carbon monoxide. Carbon monoxide is produced during the incomplete combustion of carbon-containing fuels such as coal, oil, natural gas, etc. For example, if the air supply is insufficient when using a coal stove for heating in a poorly ventilated room, the coal will not burn completely, producing a large amount of carbon monoxide, which is prone to cause poisoning accidents.

[0033] Industrial production process: Carbon monoxide is also produced in many industrial processes. For example, in the steel industry, ironmaking blast furnaces produce carbon monoxide during the ironmaking process. The chemical equation is high temperature, and the carbon monoxide produced is used as a reducing agent to reduce iron ore (mainly composed of Fe2O3).

[0034] Automobile exhaust: When automobile engines burn gasoline or diesel, carbon monoxide is also produced due to the non-ideal combustion conditions in the combustion chamber. Carbon monoxide in exhaust gas is one of the important sources of urban air pollution.

[0035] Use

[0036] Industrial use

[0037] Metallurgical industry: As mentioned earlier, carbon monoxide is used as a reducing agent to extract metals from ores. In the ironmaking process, carbon monoxide reduces iron from iron ore, and the reaction equation is high temperature.

[0038] Chemical raw materials: Carbon monoxide is an important component of synthesis gas (mainly composed of carbon monoxide and hydrogen). Synthesis gas can be used to produce a variety of chemical products, such as methanol, through the reaction of carbon monoxide and hydrogen: catalyst.

[0039] Gaseous fuel: Carbon monoxide combustion can release a large amount of heat and can be used as fuel. For example, water gas (mainly composed of carbon monoxide and hydrogen) can be used as fuel for industrial furnaces and kilns, and has wide application in glass manufacturing, ceramic firing, etc.

[0040] The device overview of a CO removal device is as follows:

[0041] Carbon monoxide (CO) removal device is a device for removing carbon monoxide components in mixed gas. It has a wide range of applications in many fields such as chemical industry, environmental protection, industrial gas purification, etc. For example, in the ammonia synthesis industry, a small amount of carbon monoxide in the raw material gas will poison the synthesis catalyst, so it needs to be removed by this device.

[0042] Main components

[0043] Absorption tower

[0044] This is one of the core parts of the device. The absorption tower usually contains an absorbent for chemical reaction or physical adsorption with carbon monoxide. Common absorbents include copper ammonia solution, methanol, etc.

[0045] Taking copper ammonia solution as an example, carbon monoxide will form a complex with copper ions and be absorbed. In the absorption tower, gas and absorbent are in countercurrent contact, i.e. gas enters from the bottom and absorbent is sprayed from the top, which can increase the gas-liquid contact area and improve the absorption efficiency.

[0046] Regeneration tower

[0047] When the absorbent absorbs carbon monoxide to a certain extent, its absorption capacity will decrease. The role of the regeneration tower is to restore the absorption capacity of the absorbent that has absorbed carbon monoxide.

[0048] For example, for copper ammonia solution absorbent, in the regeneration tower, carbon monoxide can be desorbed from the complex by heating, reducing pressure, etc., so that the copper ammonia solution can be recycled.

[0049] Heat exchanger

[0050] Used for heat exchange. In the absorption and regeneration process, temperature is a key factor. For example, in the absorption process, if the temperature is too high, it may affect the absorption effect of the absorbent; in the regeneration process, appropriate temperature rise is beneficial to the desorption of carbon monoxide.

[0051] The heat exchanger can use the high-temperature absorbent after regeneration to exchange heat with the low-temperature absorbent about to enter the absorption tower, which not only saves energy, but also enables the absorption process to be carried out at the appropriate temperature.

[0052] Pump and compressor

[0053] The pump is mainly used to transport the absorbent to circulate between the absorption tower and the regeneration tower. The compressor is used to transport the gas to ensure that the gas can enter the absorption tower at the appropriate pressure.

[0054] For example, in some high-pressure gas purification processes, the compressor needs to compress the gas to a certain pressure to make the gas pass through the filler layer in the absorption tower smoothly and fully contact with the absorbent.

[0055] Working Principle

[0056] Chemical Absorption Method Principle

[0057] When using the chemical absorption method, the absorbent reacts chemically with carbon monoxide. For example, the reaction of carbon monoxide absorption by the copper ammonia solution mentioned above: (where Ac represents the acetate ion).

[0058] This reaction is reversible, under the conditions of the absorption tower (appropriate temperature, pressure, and absorbent concentration), the reaction proceeds to the right, carbon monoxide is absorbed; in the regeneration tower, by changing the conditions, such as increasing the temperature, reducing the pressure, the reaction proceeds to the left, carbon monoxide is desorbed.

[0059] Physical Adsorption Method Principle

[0060] Physical adsorption is based on intermolecular forces. Some adsorbent materials (such as activated carbon, molecular sieves, etc.) have a porous structure, and carbon monoxide molecules can be adsorbed in these pores.

[0061] This adsorption is a physical process, when the adsorption reaches saturation, carbon monoxide can be desorbed by reducing the pressure or increasing the temperature, and the adsorbent can be regenerated. However, the selectivity of physical adsorption for carbon monoxide is relatively poor, and in practical applications, it may need to be combined with other processes to improve the removal effect of carbon monoxide.

[0062] Application Scenarios

[0063] Chemical Industry

[0064] For example, in the synthesis gas purification process, synthesis gas (mainly composed of carbon monoxide and hydrogen) is used to produce chemical products such as methanol and synthetic ammonia. In these production processes, the content of carbon monoxide needs to be controlled within a certain range to prevent catalyst poisoning. Carbon monoxide removal devices can effectively remove carbon monoxide impurities in synthesis gas, improving product quality and production efficiency.

[0065] Environmental Protection Field

[0066] In some industrial waste gas treatment, carbon monoxide is a toxic and harmful gas. Carbon monoxide removal devices can be used to treat waste gas generated by steel plants, coking plants, etc., reducing the pollution of carbon monoxide to the atmospheric environment, and reducing its harm to human health and the ecological system.

[0067] Electronic Industry

[0068] In the production and purification process of electronic gases, the purity of the gas is extremely high. Carbon monoxide removal devices can be used to remove trace amounts of carbon monoxide in electronic-grade gases, ensuring the quality of electronic gases and meeting the requirements of high-precision processes such as electronic chip manufacturing.
