Abstract
The invention relates to a combined process for producing heat, electricity and acetylene by utilizing coal. For the combined process, a coal-fired power plant provides required raw pulverized coal, hydrogen and electric energy for acetylene producing reaction by coal plasma; coal cinder generated by a coal plasma acetylene reaction device is returned to a storage pulverizing system for generating power through combustion; the generated exhaust gas is introduced into a boiler to be combusted for reuse; and the generated waste heat is introduced into a thermodynamic system of a steam turbine for use. According to the invention, the coal plasma acetylene reaction device and a production system of the coal-fired power plant are integrated into a whole, combined production of heat, electricity and acetylene is carried out in one system, so that the reasonable collocation and gradient utilization of resources are realized, the economy of the system is improved, and the consumption of coal is reduced.
Description
technical field [0001] The invention relates to a coal polygeneration combination process, in particular to a technical scheme of coal heating, electricity and acetylene combination process. Background technique [0002] Acetylene is an important basic chemical raw material. The calcium carbide method is a traditional method for producing acetylene from coal, but there are problems such as long process flow, high energy consumption, high cost of raw material transportation, and especially serious environmental pollution. [0003] The process of coal plasma production of acetylene has low energy consumption and simple process, which is very suitable for continuous and large-scale production, and can basically achieve zero emission to the environment and does not pollute the environment. [0004] Coal plasma production of acetylene process overcomes many shortcomings of the traditional process, and is an effective way of clean coal conversion. The applicant has applied for an...
