A dual-fluid nozzle based on high-pressure water

Abstract

The invention provides a dual fluid nozzle based on high-pressure water. The dual fluid nozzle comprises a high-pressure water pipeline and a slurry pipeline. The high-pressure water pipeline is coaxially sleeved with the slurry pipeline, flowing space of the high-pressure water is arranged in the high-pressure water pipeline, and flowing space of slurry is arranged between the slurry pipeline and the high-pressure water pipeline. The slurry pipeline communicates with a slurry inlet. A slurry nozzle is formed in the tail end of the slurry pipeline. The front end of the high-pressure water pipeline is located outside the slurry pipeline and connected with a high-pressure water source. A high-pressure water nozzle is formed in the tail end of the high-pressure water pipeline and located in the slurry nozzle. When the dual fluid nozzle is used, high-pressure water flow in the high-pressure water nozzle collides with the slurry in the slurry nozzle, and the slurry is atomized into fine slurry drops to be sprayed out of the slurry nozzle. The dual fluid nozzle is simple in design structure, large in flow adjustment range, excellent in anti-blocking performance, especially suitable for high-pressure and ultrahigh-pressure environments and capable of solving the problems that in a traditional supercritical water gasification technology, a feeding device is too high in local temperature, and a feeding port is blocked.

Description

technical field [0001] The invention belongs to the technical field of supercritical water gasification, in particular to a two-fluid nozzle based on high-pressure water. Background technique [0002] Supercritical water gasification technology is a clean energy technology that has attracted much attention in recent years. Compared with water at normal temperature, supercritical water has superior properties such as low polarity, high solubility for organic matter, low viscosity, and strong transport capacity, so that organic solid raw materials can react quickly in a supercritical water environment to generate clean energy such as hydrogen . A large number of experimental results also confirmed that supercritical water gasification technology can achieve good gasification effect. [0003] However, at present, the invention or research related to supercritical water gasification technology is only focused on the gasification reaction device. There are few researches on the...
