Description

Technical Field

[0001] The present invention relates to the technical field of slab cutting, and particularly to a biomass hydrogen low-carbon slab cutting method, system and storage medium. Background Art

[0003] The processes involving slab cutting in iron and steel enterprises include: scrap steel preparation cutting, continuous casting slab cutting in steelmaking, hot-rolled plate cutting, secondary processing cutting of waste and defective materials, etc. The main cutting gas sources are coke oven gas and natural gas, etc. However, this method has the following problems: (1) High calorific value (about 4200 kcal / Nm3 for coke oven gas), low heat utilization efficiency when used for cutting; (2) High price (more than 3 yuan / m3 on average for natural gas), and restricted by tight gas sources in winter; (3) Coke oven gas contains tar, naphthalene, etc., which is easy to block equipment, and the cutting loss is high (the cutting seam width reaches 8 mm).

[0004] To solve the above problems, some enterprises use electrolyzed water to produce hydrogen and oxygen in the continuous casting slab cutting process of steelmaking, and use hydrogen and oxygen to cut slabs. An electrolyzed water hydrogen and oxygen generation device is arranged in the continuous casting slab cutting process of steelmaking. Its principle is: the electric energy from the power grid is connected to the power distribution cabinet of the hydrogen and oxygen generator. The electrolytic cell uses sodium hydroxide or potassium hydroxide alkaline aqueous solution as the electrolyte to decompose hydrogen and oxygen from water. Each cutting torch is separately equipped with a hydrogen and oxygen generator for gas supply. The hydrogen and oxygen generated by the hydrogen and oxygen generator are separately transported to each cutting torch through the pipeline between the safety flame arrester cabinet and the energy medium box for direct slab cutting.

[0005] However, the above existing technologies have the following problems: (1) The electric energy used in electrolyzed water is not directly green electricity, has no carbon fixation effect, and is poor in terms of carbon reduction effect; (2) The hydrogen supply is unstable, there is no storage and buffer tank, and it cannot be coupled with the existing hydrogen production system in the steel plant, and complementary gas supply is not formed; (3) The alkaline electrolyzed water technology used has high cost (about 5 degrees of electricity to produce 1 m3 of hydrogen), low general utilization rate of electric energy, high cost, and is not conducive to cost reduction and carbon reduction.

[0049] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0050] Figure 1 Schematically shows a flowchart of a biomass hydrogen low-carbon slab cutting method applicable to an embodiment of the present invention.

[0051] See Figure 1 , an embodiment of the present invention provides a biomass hydrogen low-carbon slab cutting method, which may include the following steps:

[0052] Step S1: Obtain biomass plants;

[0053] Exemplarily, the obtaining of biomass plants includes the steps of:

[0054] Plant biomass plants in saline-alkali land around coastal steel mills;

[0055] Regularly manage, harvest and process the biomass plants.

[0056] In the embodiments of the present application, biomass plants are planted in the saline-alkali land around coastal steel mills, and the biomass plants are regularly managed (such as fertilizing, pest control, etc.), harvested and processed for subsequent steps.

[0057] Exemplarily, the biomass plants include: Suaeda salsa, Arundo donax.

[0058] In the embodiments of the present application, the seeds of Suaeda salsa contain about 25% oil and can be used to extract oil for industrial use. Using Suaeda salsa to carry out ecological restoration on saline soil and heavy metal polluted soil can improve the physical and chemical properties of the soil, reduce the soil salinity, increase the soil organic matter and total nitrogen content, increase the number of soil microorganisms, and can have a certain impact on the composition of the soil microbial community, changing some traits of its dominant flora such as salt tolerance.

[0059] In the embodiments of the present application, Arundo donax is a very effective substitute for corn. In terms of biomass, Arundo donax is an annual plant with great yield increase potential. Its productivity can be maintained for 10 - 15 years and it can adapt to marginal soils. In addition, Arundo donax has a great advantage that it does not take away the soil fertility while producing crops. These characteristics contribute to the sustainability of the environment and the supply chain when Arundo donax is used to produce biogas.

[0060] Step S2: Prepare biomass fuel using the biomass plant;

[0061] Exemplarily, the preparing of biomass fuel using the biomass plant includes the steps of:

[0062] Regularly collect the biomass plant;

[0063] Process and produce the biomass plant to obtain biomass fuel;

[0064] Store the biomass fuel.

[0065] In the embodiments of the present application, the biomass plant is regularly collected, and biomass fuel is produced and stored using the biomass plant.

[0066] Step S3: Prepare first hydrogen using the biomass fuel;

[0067] Exemplarily, the preparing of first hydrogen using the biomass fuel includes the steps of:

[0068] Gasify the biomass fuel to obtain reaction products;

[0069] Purify the reaction products to obtain hydrogen raw materials;

[0070] Purify the hydrogen raw materials to obtain first hydrogen.

[0071] In the embodiments of the present application, hydrogen is produced by gasifying biomass fuel, including processes such as gasification, purification, and purification.

[0072] Step S4: Obtain the existing second hydrogen in the steel mill;

[0073] In the embodiments of the present application, the steel mill stores a certain amount of hydrogen by itself through a storage device for use in subsequent steps.

[0074] Step S5: Cut the slab according to the first hydrogen and the second hydrogen.

[0075] Exemplarily, the cutting of the slab according to the first hydrogen and the second hydrogen includes the steps of:

[0076] Transport the first hydrogen to the second hydrogen;

[0077] Mix the first hydrogen and the second hydrogen to obtain reaction hydrogen;

[0078] Use the reaction hydrogen to cut the slab.

[0079] In the embodiments of the present application, the hydrogen prepared from biomass fuel is complementary to the existing hydrogen in the steel plant. The two can ensure stable hydrogen supply and are transported to each user for slab cutting. The existing surplus oxygen in the steel plant can be used as the auxiliary combustion gas for hydrogen cutting.

[0080] Exemplarily, the transporting the first hydrogen to the second hydrogen includes the steps of:

[0081] Cache the first hydrogen;

[0082] Pressurize the first hydrogen.

[0083] In the embodiments of the present application, a storage tank is provided for storing and buffering the hydrogen prepared from biomass fuel, pressurizing the hydrogen to prevent insufficient pressure when mixing with the existing surplus oxygen in the steel plant.

[0084] In summary, the embodiments of the present invention provide a method for cutting low-carbon slabs with biomass hydrogen. Through a series of steps, this method aims to solve the problems of high carbon emissions and inefficient energy utilization in the process of slab cutting in the steel industry. The following is a detailed analysis of how this method solves the technical problems:

This method uses biomass plants (such as Suaeda salsa and Arundo donax) to prepare biomass fuel and further convert it into hydrogen, achieving energy acquisition from renewable resources, thereby significantly reducing carbon emissions.

[0086] Improve energy utilization efficiency: Biomass fuel, as a renewable energy source, usually has a higher energy utilization efficiency than fossil fuels. By steps such as gasification, purification, and refining, hydrogen is efficiently prepared from biomass fuel, further improving energy utilization efficiency.

The preparation of biomass fuel and the production of hydrogen form a closed-loop energy utilization system, achieving resource recycling.

[0088] Enhance system flexibility and stability: This method combines biomass hydrogen and the existing hydrogen in the steel mill to form a complementary energy supply system. In the case of insufficient supply of biomass hydrogen, the existing hydrogen in the steel mill can ensure the continuous progress of the cutting process, enhancing the flexibility and stability of the system.

[0089] The creativity of this method is mainly reflected in the following aspects:

[0090] Innovative utilization of biomass resources: Using biomass plants as raw materials for preparing biomass fuels and hydrogen is an innovative way of energy utilization. By planting biomass plants in saline-alkali land around coastal steel mills, the effective utilization of idle land is achieved, and the soil environment is improved, which is an innovation in traditional land use methods.

[0091] Integration and optimization of the energy system: This method combines biomass hydrogen with the existing hydrogen in the steel mill to form a complementary energy supply system. This integration not only improves energy utilization efficiency but also enhances the flexibility and stability of the system, which is an innovation in traditional energy supply systems.

[0092] Low-carbon and environmentally friendly cutting method: This method provides a low-carbon and environmentally friendly slab cutting method, which helps to reduce carbon emissions in the steel industry. By using renewable resources and optimizing energy utilization, this method meets the current global pursuit of sustainable development and is an innovation in traditional cutting methods.

[0093] Combination of technological innovation and practical application: This method not only has theoretical innovation but also considers the feasibility and economy in practical application. Through reasonable step design and system integration, this method can be effectively implemented and promoted in the steel industry, realizing the close combination of technological innovation and practical application.
