Description

Technical Field

[0001] The present invention relates to an intelligent proportion control system for slurry preparation in a gasification process of organic waste liquid and solid waste water-coal slurry, and more specifically, to an intelligent pulping proportion control system for regulating the types and proportions of multi-ply pulping raw materials of water-coal slurry according to the flow rate and composition of synthesis gas output by a gasifier. Background Art

[0002] China's fossil energy is characterized by "rich in coal, poor in oil, and little gas". Coal is the most important energy source in my country. The development of clean and efficient coal utilization technology has become an important part of my country's energy transformation and the realization of carbon neutrality goals. Coal conversion technology is an important means to achieve clean and efficient utilization of fossil fuels. Coal gasification technology is one of the core technologies of coal conversion technology. It is a clean and efficient thermochemical technology that generates synthesis gas containing H2, CO, and CO2 through the thermochemical reaction of coal. The synthesis gas can be used for power generation or as a chemical raw material to synthesize ammonia and methanol, etc. It can also be used in coal liquefaction, cycle combined power generation and coal gasification polygeneration.

[0003] Coal-water slurry is a new type of coal-based clean liquid fuel that replaces oil. It is composed of 65%-70% coal, 30-35% water and a small amount of additives. It is a fluid fuel made through a certain processing technology. It is an important raw material form for gasifiers and plays an important role in the production of synthetic gas in coal chemical industry. Coal-water slurry gasification has gradually become the main form of coal gasification technology and has been widely used in my country's coal chemical industry. At present, my country has become the country with the largest coal-water slurry production capacity, the most extensive application industry and the most advanced technology in the world.

[0004] The main components of water-coal slurry are clean water and coal. Studies have shown that industrial wastewater (chemical wastewater, fermentation wastewater, pharmaceutical wastewater, etc.) and some organic solid waste (industrial leather slag, waste plastics, activated carbon, urban sludge, etc.) with complex components and difficult to biochemically treat can be mixed in a specific proportion to prepare water-coal slurry, which not only reduces the use of clean water and coal, but also achieves simple and efficient waste treatment and reuse while preparing energy. At the same time, in the process of gasification of waste liquid / solid waste water-coal slurry, harmful organic substances in waste liquid / solid waste can be converted into synthesis gas for downstream industries through gasification reaction, and heavy metals are fixed in molten slag for building materials, etc. The whole process realizes the harmless treatment of waste. Therefore, the waste liquid / solid waste water-coal slurry gasification process is a new coal chemical technology with both economic and environmental benefits, and has broad application prospects.

[0005] At present, some enterprises have started to apply the waste liquid / solid waste water coal slurry gasification process to produce synthesis gas to provide chemical raw materials or fuel gas for downstream industries. Different industries have different requirements for the components in the synthesis gas. For example, the requirements for the ratio of CO and H2 when the synthesis gas is used as civil coal gas, metallurgical reduction gas or combined cycle power generation gas are different. If the water coal slurry gasification process is used to prepare hydrogen, the H2 ratio in the synthesis gas is required to be as high as possible. Therefore, being able to adjust the synthesis gas ratio in a timely and accurate manner according to demand is one of the important links in the application of this process. For a given gasifier, the shape and size of its combustion chamber and the gasification pressure are fixed, while the gasification temperature, gasifying agent and the mass flow rate of coal slurry are determined by the oxygen-coal ratio. The composition and concentration of coal slurry become the key factors affecting gasification. At present, the determination of the composition and concentration of waste liquid / solid waste water coal slurry mainly relies on the manual selection of waste liquid, solid waste, additives and coal for laboratory trial production of water coal slurry. When the types of industrial waste liquid, solid waste, coal, additives and other raw materials change, it is necessary to repeat the test and then manually adjust the ratio of waste liquid / solid waste water coal slurry raw materials according to the test results. It is not only time-consuming and laborious, but also the laboratory data and engineering operation data are quite different, which affects the synthesis gas production and composition. Therefore, it is particularly important to develop an intelligent system that can automatically adjust the ratio of waste liquid / solid waste water coal slurry slurry raw materials according to the demand for water coal slurry gasification synthesis gas components. Summary of the invention

[0006] The purpose of the present invention is to provide an intelligent pulping ratio control system for automatically adjusting the types and proportions of water-coal slurry slurry raw materials (including: organic waste liquid, organic solid waste, coal, additives) according to the water-coal slurry concentration and synthesis gas composition for the water-coal slurry gasification process of multiple organic waste liquids and solid wastes. The system controls the mass of different pulping raw materials added to the rod mill and adjusts the rotation speed of the rod mill, so that the prepared waste water-coal slurry meets the gasification requirements and can produce the synthesis gas flow rate and component ratio that meet industrial needs, reduce the labor cost and resource waste caused by changes in pulping raw materials or changes in synthesis gas component requirements, and improve the overall efficiency and economic benefits of the organic waste liquid and solid waste water-coal slurry gasification process.
