Abstract

The invention discloses a garbage gasification coupling hydrogen production system which comprises a garbage gasification furnace, a slag pool, a high-temperature cyclone separator, a waste heat recovery device, a spray washing tower, a wastewater and waste liquid treatment device, a preheater, a reforming converter, a PSA, a hydrogen storage tank, a CCUS and a carbon dioxide storage tank. The system is compact in arrangement, simple to operate and easy to implement. The existing conditions of a waste incineration power plant are fully utilized, coupling of waste power generation and hydrogen production is achieved, and the quality of a waste treatment final product is improved; according to the invention, the garbage is treated in a gasification manner, so that harmlessness, reduction and recycling of garbage treatment in a real sense are realized; and according to the hydrogen production process, the carbon emission of a waste incineration power plant is greatly reduced, and the waste power generation coupling hydrogen production process has the beneficial effects of zero carbon and high efficiency.

Description

technical field [0001] The invention relates to the field of waste incineration and disposal, in particular to a waste gasification coupled hydrogen production system. Background technique [0002] Waste incineration is the main method of waste treatment at present, and it is also one of the main means to maximize the reduction and harmlessness of waste. However, in the process of waste incineration, highly toxic and other harmful substances such as dioxin and heavy metals will be produced. The fly ash belongs to the category of hazardous waste management, and the waste incineration power plant will also generate a large amount of carbon dioxide, which increases the pressure on carbon dioxide emission reduction. [0003] In 2020, the National Energy Administration officially listed hydrogen energy as an energy category. Hydrogen energy is one of the important sources of zero-carbon energy and an important direction for the development of clean energy in the future. The ind...
