Description

Technical Field

[0001] The utility model belongs to the technical field of mixed gas combustion, and in particular relates to a mixed gas combustion cracking test analysis platform. Background Art

[0002] Currently, simulating the combustion state and reaction process of an ammonia cracking furnace is a crucial task, crucial for improving industrial production efficiency, optimizing energy utilization, and protecting the environment. An ammonia cracking furnace is a device used to produce hydrogen. Its core function is to produce hydrogen by cracking ammonia at high temperatures. During this process, ammonia passes through the catalyst within the cracking furnace, causing a series of chemical reactions to produce hydrogen and other byproducts. Therefore, accurately simulating the combustion state and reaction process of an ammonia cracking furnace is crucial for optimizing reaction conditions within the furnace and increasing hydrogen production.

[0003] To simulate the combustion state of an ammonia cracking furnace, it is typically necessary to consider a variety of factors, such as the furnace temperature distribution, gas flow rate, and catalyst activity. These factors not only affect the ammonia cracking efficiency but also directly impact the hydrogen production and quality. By incorporating advanced numerical simulation techniques, it is possible to construct a three-dimensional flow and temperature field model within the furnace, thereby analyzing the combustion state under different operating conditions. For example, by adjusting the gas flow rate and temperature distribution within the furnace, it is possible to optimize the ammonia cracking process and increase hydrogen production.

[0004] To simulate the reaction process in an ammonia cracking furnace, in-depth research is needed into the mechanism and kinetics of the ammonia cracking reaction. By incorporating quantum chemical calculations and experimental verification, the key steps and rate-controlling factors of the ammonia cracking reaction can be revealed. Furthermore, the activity of the catalyst within the furnace and its influence on the reaction process must be considered. By simulating the effects of different catalysts in the cracking reaction, it is possible to screen for catalysts with superior performance, thereby improving ammonia cracking efficiency and hydrogen quality.

[0005] In recent years, numerous researchers have discovered effective methods for optimizing reaction conditions within ammonia cracking furnaces through computer simulations of the combustion and reaction processes within the furnaces. These methods include adjusting the temperature distribution within the furnace, optimizing gas flow rates, and improving catalyst performance. These research findings not only improve the production efficiency of ammonia cracking furnaces but also provide more environmentally friendly and sustainable solutions for industrial production.

[0006] Furthermore, simulations can be conducted to understand how ammonia cracking occurs under the high-temperature conditions of the cracking furnace, how the catalyst plays a key role, and how hydrogen continuously flows out of the furnace. These simulations can help people better understand the working principles of ammonia cracking furnaces.

[0007] In summary, simulating the combustion state and reaction process of an ammonia cracking furnace is a significant undertaking. By thoroughly studying the mechanism and kinetics of the ammonia cracking reaction and optimizing the reaction conditions within the furnace, we can improve the furnace's production efficiency, enhance hydrogen quality, and ultimately provide a more environmentally friendly and sustainable solution for industrial production.

[0008] However, the experimental process simulated by computer is relatively theoretical and there is still a certain gap between it and the actual combustion and cracking process. Therefore, it is of great significance to design and develop a mixed gas combustion and cracking test analysis platform. Utility Model Content

To this end, the gas mixing unit also includes a gas mixing tank installed between the outlet of each gas source pipeline and the inlet of the gas mixing pipeline. It should be noted that a sampling point can be set on the gas mixing tank.

[0056] On the basis of any of the above embodiments, in order to improve the safety of the test, the high-pressure gas needs to be decompressed first and then mixed.

[0069] During operation, the gas mixing pipeline supplies gas to each of the multiple branch pipelines, and the gas discharged from the branch pipeline enters the gas supply pipe 3-8 for mixing, and then is discharged through the porous gas guide plug 3-11. An igniter 3-9 is provided on the upper surface of the gas guide plug 3-11; after the igniter 3-9 ignites the gas, the porous gas guide plug 3-11 can effectively burn the gas evenly. In addition, it also plays a role in stabilizing the gas pressure during gas combustion.

[0070] Each branch pipeline in this embodiment has a one-way function, and the multiple holes on the upper end of the component can self-contained fire prevention function.

[0096] A mixed gas combustion analysis test method utilizes the above-mentioned mixed gas combustion cracking test analysis platform to complete the following test steps:

[0097] S1. Inject protective nitrogen into the combustion unit;

[0098] When operating a combustion unit, a crucial first step is to inject protective nitrogen into the combustion unit. This step is crucial, as it effectively prevents dangerous phenomena such as deflagration and explosions caused by ignition of residual gases. Prior to this operation, the furnace hood must be pre-filled with nitrogen as a safety precaution. Throughout this process, correct procedures must be strictly adhered to, and no detail should be overlooked.

[0099] S2. Set the opening of the control valve group on each gas source pipeline according to the ratio of the mixed gas. This opening setting can be achieved through automatic gas distribution or manual gas distribution.

[0100] The process of automatic gas distribution is as follows: according to the ratio of the mixed gas, the flow controller on each gas source pipeline is directly set to the opening, or the controller sends an opening instruction to the flow controller on each gas source pipeline;

[0101] During automatic gas distribution and mixed combustion, on the one hand, the flow controller and pneumatic valve are remotely and accurately controlled online through the control platform; on the other hand, the opening status of the flow controller and pneumatic valve are displayed and data is monitored and saved through the control interface of the control platform. The automatic gas distribution process can be time-controlled by the flow controller of each branch, thereby realizing quantitative control of gas charging and meeting the requirements of simultaneous gas distribution.

[0102] Automatic control can be carried out in a linkage manner. You only need to adjust the working time and flow of the flow controller according to the test requirements, and then you can start or stop the gas distribution system with one button. If manual gas distribution is required, you only need to make sure that the automatic gas distribution program is in the off state.

[0103] The manual gas distribution process is as follows: manually setting the opening of the mechanical valve on each gas source pipeline according to the ratio of the mixed gas;

[0104] The manual gas distribution part can be used as a backup means. If the automatic gas distribution part alarms and needs maintenance, the manual gas distribution can replace the automatic gas distribution part to continue working. During the manual gas distribution process, the mechanical valve and flow meter in each branch need to be adjusted separately. After the adjustment is completed, gas can be distributed simultaneously. If the flow changes according to the test requirements, the mechanical needle valve of each branch needs to be readjusted separately.

[0105] Manual gas distribution can also be used as the second set of gas distribution mixing scheme. If the test requires manual distribution, the manual gas distribution part can be used for mixed combustion and cracking.

[0106] S3. Start the ignition device in the combustion unit to make the mixed gas entering the combustion unit burn; during the combustion process:

[0107] The first data acquisition unit is used to collect the combustion and cracking state of the mixed gas in the combustion unit; specifically, the first data acquisition unit is used to collect the gas reaction flow imaging record and temperature during the combustion and cracking of the mixed gas in the combustion unit;

[0108] The tail gas generated by the combustion unit is analyzed using the second data acquisition unit; specifically, before the tail gas generated by the combustion unit is analyzed using the second data acquisition unit, the tail gas is cooled so that the tail gas temperature during analysis is no greater than 30°C.

[0109] S4. After the test is completed, inject ammonia into the pipeline to clean the pipeline.

[0110] In summary, the platform in this application has the following functions:

[0111] (1) Control the timing and fuel quantity of automatic gas distribution, as well as the start and stop of automatic components (flow controller, pneumatic valve);

[0112] (2) Data collection: data from all temperature sensors, pressure sensors, flow controllers, alarms, analyzers, etc. in the platform can be displayed and automatically stored;
