Description

Technical Field

[0001] The invention belongs to the technical field of chemical engineering, and in particular relates to plasma processing equipment for hydrogen-containing gas. Background Art

[0002] Existing US20230294986 discloses a device for obtaining gaseous hydrogen from hydrocarbon gas, the heat exchanger provides heat exchange between the unheated hydrocarbon gas flow and the heated gas leaving the device, thereby improving the efficiency of the device. Existing US20170349758A1 proposes a method for obtaining carbon black from hydrocarbons. After the raw materials are introduced, the mixture is expanded to divert the flow away from the furnace wall, recirculate the fully formed carbon black, and prevent the formed product from reaching the reactor wall. The carbon black obtained by this process is claimed. Patent WO2022023287A1 proposes a technical process for obtaining hydrogen-containing gas and a single solution at the key equipment level that allows optimization of the process. The device is configured in such a way that the inlet hydrocarbon gas cracking operation is performed without changing the temperature. The plasma gas is a mixture containing hydrogen and / or hydrocarbons, wherein the device includes a separator downstream of the reactor, which is configured to ensure that the gas mixture at the outlet of the reactor is separated into outlet gas and solid carbon products, and a portion of the outlet gas is re-injected into the carrier gas. It is possible to utilize the pipeline pressure of the raw material supply, heat recovery, and electrode supply to increase the service life of the plasma generator used.

[0003] The above patents propose methods and devices, in which only the plasma pyrolysis technology of hydrocarbons (methane, natural gas) is considered to be possible with the production of hydrogen and solid carbon materials, while in various solutions, these processes are aimed at obtaining one target claimed product of hydrogen or solid carbon. The proposed device and method do not cover other hydrogen-containing substances such as ammonia and hydrogen sulfide as raw materials at all. The proposed solution is not suitable for other types of raw materials for the production of other target products. In the proposed solution, the plasma-forming gas is first heated and then enters the plasma chemical reactor, and the raw materials are fed separately through the supply system, which greatly complicates the design of the plasma reactor and shortens its trouble-free operation time. In addition, the conversion rate of the raw materials and the energy efficiency of the process are still at a relatively low level. This causes the problem of low output of existing plasma treatment equipment for hydrogen-containing gas mixtures.

[0004] Therefore, we propose a plasma processing equipment containing hydrogen gas to solve the above problems. Summary of the invention

[0031] The technical solutions in the embodiments of the invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all of the embodiments.

[0032] Reference Figure 1 , a plasma treatment device for hydrogen-containing gas, including a pyrolysis-generated hydrogen and solid carbon treatment mechanism, the pyrolysis-generated hydrogen and solid carbon treatment mechanism includes a first plasma torch 1, the first plasma torch 1 is connected to a first plasma chemical reactor 2, the first plasma chemical reactor 2 is connected to a solid carbon separator 3, and the solid carbon separator 3 is connected to a first gas flow separator 4. Reagents, argon and methane are fed into the first plasma torch 1 and heated to a high temperature (5000-20000K) under the action of an AC arc. Next, they enter the first plasma chemical reactor 2 to complete the plasma pyrolysis process. Due to the gas vortex generated by the tangential flow of the gas in the channel of the first plasma torch 1, these components are fully mixed in the volume of the first plasma chemical reactor 2 to form a complete mixed reactor, and the reaction zone and the temperature zone are displaced along the axis of the reactor. After the methane decomposition reaction is completed, the hydrogen must be separated from the product heterogeneous mixture containing hydrogen, unreacted methane, other light hydrocarbons, solid carbon and inert gas. Next, the heterogeneous flow is filtered.

[0033] Reference Figure 2, and also includes a hydrogen sulfide pyrolysis mechanism, which includes a second plasma torch 5, the second plasma torch 5 is connected to a second plasma chemical reactor 6, the second plasma chemical reactor 6 is connected to a sulfur-water separator 7, and the sulfur-water separator 7 is connected to a second gas flow separator 8. Hydrogen sulfide is heated using arc plasma, and solid sulfur must be removed from the gas flow after the plasma passes through the second plasma chemical reactor 6. The purified gas flow contains hydrogen, inert gas and unreacted hydrogen sulfide, and is divided into three flows.

[0034] The inert gas is again fed into the second plasma torch 5, and the unreacted hydrogen sulfide is mixed with fresh hydrogen sulfide.

[0035] Reference Figure 3 , also includes an ammonia pyrolysis mechanism, which includes a plasma torch 9, the plasma torch 9 is connected to a third plasma chemical reactor 10, the third plasma chemical reactor 10 is connected to an ammonia water separator 11, the ammonia water separator 11 is connected to a third gas flow separator 12, and the third gas flow separator 12 is connected to an absorber 13. Hydrogen is separated from its mixture with nitrogen by pressure cycle adsorption. Ammonia and nitrogen are fed into the plasma torch 9 so that they are heated by the electric arc. The reaction develops rapidly and is completed in the third plasma chemical reactor 10. The product gas mixture is cooled with water in the ammonia water separator 11. The mixture is then cooled, then absorbed and dried by the absorber 13, and separated into separate gas components by pressure swing adsorption.

[0036] Reference Figure 4 , also includes a plasma carbon dioxide reforming mechanism, the plasma carbon dioxide reforming mechanism includes a third plasma torch 14, the third plasma torch 14 is connected to a fourth plasma chemical reactor 15, the fourth plasma chemical reactor 15 is connected to a fourth gas flow separator 16, and the fourth gas flow separator 16 is connected to a gas flow cooler 17. The speed of plasma carbon dioxide reforming is very slow, and the third plasma torch 14 must be used, in which the development and complete completion of the chemical reaction occurs. An important feature of the plasma process using the AC third plasma torch 14 is that the deep coupled vortex of the plasma torch and the plasma reactor propagates inside the reactor, which is achieved by introducing the reagent tangentially into the third plasma torch 14. The reagents are effectively mixed in the fourth plasma chemical reactor 15 (more than 70% of the methane reacts with the carbon dioxide in the reactor, rather than in the plasma torch channel). Only a small amount of methane is converted into smoke. After the carbon dioxide reforming is completed, the reaction mixture is cooled and purified by mechanical filtration of the smoke particles. The gas mixture is separated into separate components by absorption methods and pressure swing adsorption.

[0037] The main flow of raw materials (50-100%) is supplied through the plasma torch and is the plasma forming gas. When the raw materials interact with the arc, the plasma chemical reaction starts inside the plasma torch volume. In addition, the flow of plasma and plasma forming gas (raw materials) flows from the volume of the plasma torch to the volume of the plasma chemical reactor, where the plasma chemical processes take place until they are completed. In order to achieve the maximum energy efficiency of the process and the maximum conversion of the raw materials into the target products, gas dynamic and electrokinetic mixing of the gas flow (raw materials) is used in the volume of the plasma chemical reactor, which ensures the most efficient process of energy transfer from the arc to the raw materials, as well as a homogeneous mixing of the raw materials components in the volume of the plasma chemical reactor.

The first airflow separator 4, the second airflow separator 8, the third airflow separator 12 and the fourth airflow separator 16 have the same structure. After the gas enters the shell 18, it spirals downward along the shell 18, and utilizes the condensation effect of the shell 18, and at the same time utilizes the fact that the mass of the condensed liquid is greater than that of the gas, so that the liquid is attached to the shell 18 by the centrifugal force of the rotation and accumulates at the lower part of the shell 18, and the gas rises through the air guide tube 20 into the upper part of the shell 18 and is discharged from the upper part of the shell 18.
