Double-fluid internal mixing type nozzle based on high-pressure water

Abstract

The invention provides a double-fluid internal mixing type nozzle based on high-pressure water. The double-fluid internal mixing type nozzle comprises a high-pressure water pipe and a connection part; a high-pressure water nozzle is opened in the tail end of the high-pressure water pipe; the front end of the connection part is connected with the tail end of the high-pressure water pipe; a jetting nozzle is opened in the tail end of the connection part; the connection part is internally provided with an internal mixing cavity and a plurality of slurry channels; the axes of the slurry channels are vertically crossed with that of the high-pressure water nozzle; the inner ends of the slurry channels are slurry nozzles; the slurry nozzles and the high-pressure water nozzle are communicated with the internal mixing cavity; the internal mixing cavity is communicated with the jetting nozzle. After high-pressure water flow in the high-pressure water pipe is sprayed out from the high-pressure water nozzle, the high-pressure water flow collides with slurry sprayed out from the slurry nozzle and the slurry is crushed and atomized to form slurry drop under the action of impacting and shearing effects of the high-pressure water flow; and then, the slurry drops are sprayed out from the jetting nozzle. The double-fluid internal mixing type nozzle is simple in design structure and large in flow adjusting range and is especially suitable for high-pressure and ultrahigh-pressure environments.

Description

technical field [0001] The invention belongs to the technical field of supercritical water gasification, in particular to a two-fluid internal mixing 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. It uses the excellent physical and chemical properties of water above the critical point (Tc=647K, Pc=221bar) to convert various organic solid materials and organic Technology that converts waste water, etc. into clean energy such as hydrogen. Supercritical water has the advantages of high diffusion coefficient, low viscosity, and is a good solvent for various organic substances. It can quickly react various organic solid raw materials and organic wastewater in a supercritical water environment to generate hydrogen and other clean energy. [0003] However, the operating pressure of the supercritical water gasifier is higher than the critic...
