Description

Technical Field

[0001] The utility model relates to the technical field of CO gas elimination, in particular to an experimental CO gas intelligent elimination test device. Background Art

[0002] In scientific research and industrial production, carbon monoxide (CO) gas poses a serious threat to human health and environmental safety due to its high toxicity and flammability. In particular, the generation of CO gas is particularly common in coal mining, chemical experiments, material combustion and other processes. As a colorless and odorless gas, CO can quickly bind to human hemoglobin, hindering the transport of oxygen, causing suffocation or even death. Therefore, the development of effective CO gas elimination technology is of great significance to ensure the safety of laboratory personnel and promote the sustainable development of scientific research and industrial production.

[0003] Traditional methods for eliminating CO gas mainly include physical adsorption, chemical absorption and catalytic oxidation. Although the physical adsorption method is easy to operate, its adsorption efficiency is low and it is easily affected by the ambient temperature and humidity. Although the chemical absorption method has a high elimination efficiency, it often requires the use of a large amount of chemical reagents, there is a risk of secondary pollution, and the processing cost is high. The catalytic oxidation method can effectively convert CO gas into harmless carbon dioxide, but it needs to be carried out under specific temperature and pressure conditions, and has high requirements for equipment.

[0004] With the development of science and technology, people's research on CO gas elimination technology has continued to deepen, and new CO gas elimination technologies have been proposed one after another. Among them, the method of using water mist to react with CO gas has attracted widespread attention due to its advantages such as high efficiency, environmental protection, and low cost. The water mist method atomizes water into fine droplets, increases the contact area with CO gas, promotes the dissolution and reaction of CO gas, and thus achieves rapid elimination of CO. In addition, by adding specific chemical reagents to water, such as metal ion salts, rare earth element ions, etc., the absorption efficiency of water mist on CO can be further improved.

[0005] However, most of the existing water mist CO gas elimination devices are designed for industrial applications, and have problems such as large size, complex operation, and high cost, which makes it difficult to meet the needs of laboratory environments for CO gas elimination technology. The requirements of laboratory environments for CO gas elimination technology mainly include: high elimination efficiency, simple operation, low cost, strong adaptability, etc. Therefore, it is particularly important to develop a CO gas intelligent elimination test device specifically for laboratory environments.

[0017] The experimental CO gas intelligent elimination test device of this embodiment mainly utilizes the reaction between CO and water mist at high temperature. The water mist and CO can fully contact each other to accelerate the reaction speed, thereby accelerating the elimination efficiency of CO. At the same time, the CO content data can be monitored and recorded in real time through the CO sensor 6. The monitoring system can also analyze the elimination effect of CO gas through the computer 7, providing a scientific basis for safe production in coal mines.

[0018] In this embodiment, a flow meter 8 (purchased directly from the market, and its specific structure is not described in detail) is provided on the pipeline of the air outlet of the air compressor 2. The air compressor 2 provides air at a certain pressure to ensure that the water mist can enter the CO elimination reaction chamber 1; the flow meter 8 is used to accurately control the air flow rate to ensure sufficient mixing of the water mist and the air, and also has a display function, which can display the current flow rate indication in real time.

[0019] In actual use, in order to facilitate observation of the reaction conditions in the CO elimination reaction chamber 1 , a transparent quartz glass window 9 is provided on the upper side wall of the CO elimination reaction chamber 1 .

[0020] The experimental CO gas intelligent elimination test device has a set of precise and efficient operating procedures, including:

[0021] First, the operator needs to inject water into the water mist generator 4 through the water inlet of the water mist generating chamber, then start the water mist generator 4, and then close the second valve for 30 seconds to one minute to promote the uniform distribution of water mist in the water mist generating chamber to form a fine water mist environment; after this process is completed, close the water mist generator 4 and prepare for the next operation;

[0022] Next, the operator first closes the first valve, turns on the electric heating device 5 to heat the CO elimination reaction chamber 1 to above 800°C, then starts the air compressor and carefully adjusts the flow rate to an appropriate level to ensure that the water mist can be smoothly and evenly transported to the CO elimination reaction chamber 1; at the same time, the CO gas cylinder 10 can be used to slowly flow the CO gas into the CO elimination reaction chamber 1, so that CO fully contacts and reacts with the water mist, and the reaction equation is:

[0023] CO+H 2 O → CO 2 +H 2 .

[0024] During the reaction of CO gas and water mist, the CO content in the CO elimination reaction chamber 1 is monitored in real time by the CO sensor and transmitted to the connected computer in real time. The operator can observe the CO elimination effect in real time and adjust the operating parameters according to the data feedback to optimize the elimination efficiency.

[0025] Finally, open the first valve and keep the air compressor running to safely discharge the treated gas in the reaction chamber, including the residual CO gas, to the outdoor environment. This step not only ensures the complete removal of CO gas, but also ensures the continuous operation of the device and the continuous safety of the use environment.

[0026] The technical solution of the present utility model is not limited to the above-mentioned specific embodiments, and all technical variations made according to the technical solution of the present utility model fall within the protection scope of the present utility model.
