Pre-mixing device for sulfur-iodine cycle hydrogen production system and sulfur-iodine cycle hydrogen production system

Abstract

Relating to the technical field of sulfur-iodine cycle hydrogen production, the invention discloses a pre-mixing device for a sulfur-iodine cycle hydrogen production system and the corresponding sulfur-iodine cycle hydrogen production system. The pre-mixing device consists of: a reaction kettle, which is internally provided with a feeding solution prepared in advance; at least one feed pipe, with one end of each feed pipe being located outside the reaction kettle, and the other end being located below the liquid level of the feeding solution, and with the return material of the hydrogen production system entering the reaction kettle through the at least one feed pipe; a discharge pipe that is located at the bottom of the reaction kettle and has a discharge valve, and is connected to a Bunsen reactor of the hydrogen production system; a pressure control apparatus for controlling the pressure in the reaction kettle; and a temperature control apparatus for controlling the temperature in the reaction kettle. With the pre-mixing device provided by the invention, the feeding solution and the return material can be fully mixed to reach a good Bunsen reaction condition, and the efficiency of sulfur-iodine cycle hydrogen production is greatly improved.

Description

technical field [0001] The invention relates to the technical field of sulfur-iodine cycle hydrogen production, in particular to a premixing device of a sulfur-iodine cycle hydrogen production system and a corresponding sulfur-iodine cycle hydrogen production system. Background technique [0002] Hydrogen energy is considered to be one of the most effective measures to solve energy supply security and reduce greenhouse gas emissions. Due to its advantages of rich sources, storage and regeneration, and non-polluting combustion, it can meet the requirements of resources, environment, and sustainable development at the same time, so the current research on hydrogen production, hydrogen storage, and hydrogen energy utilization has attracted much attention. In terms of hydrogen production, efficient, low-cost and large-scale hydrogen production technology is the development direction of future industrialization. The thermochemical cycle hydrogen production method has received wi...

Problems solved by technology

[0007] In the prior art, the feed and return materials for hydrogen production are directly sent into the Bunsen reactor (Bunsen reactor). Since there are gas-solid-liquid heterogeneous phases in the feed and return materials, and the temperature is not uniform, the The poor mixing of materials in the Bunsen reactor affects the reaction conditions of the Bunsen reaction, thereby seriously reducing the efficiency of sulfur-iodine cycle hydrogen production
