Waste incineration power generation coupled water electrolysis hydrogen production system

Abstract

The invention provides a waste incineration power generation and water electrolysis hydrogen production coupled system which comprises a waste incineration power generation mechanism and a water electrolysis hydrogen production mechanism, and the waste incineration power generation mechanism is used for supplying power to the water electrolysis hydrogen production mechanism. The water electrolysis hydrogen production mechanism supplies hydrogen and oxygen to the waste incineration power generation mechanism through a first pipeline and a second pipeline correspondingly, and the pure water preparation mechanism is connected with the waste incineration power generation mechanism through a third pipeline and used for introducing dead steam. According to the water electrolysis hydrogen production system, the waste incineration power generation system is coupled with the water electrolysis hydrogen production system, waste heat generated in the waste incineration power generation process serves as a heat source in the membrane distillation process, pure water needed by water electrolysis hydrogen production is prepared, and the water electrolysis hydrogen production system has the advantages that the waste incineration power generation system is coupled with the water electrolysis hydrogen production system; the energy consumption required by pure water preparation is reduced, and the energy conversion efficiency of waste incineration power generation is improved.

Description

technical field [0001] The present application relates to the technical field of hydrogen production by electrolysis, in particular to a hydrogen production system coupled with waste incineration power generation and electrolysis of water. Background technique [0002] In recent years, with the increase of domestic waste and the increasing shortage of land resources, more and more countries have adopted the method of incineration to deal with domestic waste. At present, the heat generated in the process of waste incineration is mostly used for power generation, but this method is harmful to the heat. The utilization efficiency is low, and it is necessary to find a way to further utilize the exhaust steam after power generation to improve energy utilization efficiency. Another important issue in the waste incineration process is the control of the incineration temperature to prevent the generation of harmful substances. Since domestic waste in my country usually has a high w...

Problems solved by technology

Since domestic waste in our country usually has the characteristics of high water content, it is usually necessary to add a combustion enhancer to increase the combustion temperature to ensure that the waste is fully burned, which increases the difficulty of waste disposal
