Title:
CONTROLLER FOR CONTROLLING FORMATION OF ULTRAFINE POWDER PARTICLES
Document Type and Number:
WIPO Patent Application WO/2022/156229
Kind Code:
A1
Abstract:
A controller for controlling the formation of ultrafine powder particles. The controller has a front end connected to a front fitting device, and a rear end connected to a rear fitting device. The controller comprises an outer layer housing structure (1), an intermediate thermal preservation layer (2), and an inner layer thermal conduction layer (3); the outer layer housing structure (1) is of a sleeve structure, and the sleeve structure is used for circulating a coolant; the middle thermal insulation layer (2) is of a single-layer or multi-layer structure; and the inner layer thermal conduction layer (3) forms a channel subjected to thermal preservation treatment and is used for indirectly controlling, by means of thermal conduction or thermal radiation, the temperature of a substance circulating in the channel. By means of a design of controlling the temperature of different areas in the inner layer channel, the velocity of fluid-carrying gas, and the cross-section size of a pipeline, a thermal preservation structure controls the velocity of the fluid-carrying gas passing through areas in the inner channel; stable and controllable temperature field and velocity field create conditions for the formation of ultrafine powder particles, such that particles having desired particle size and morphology are prepared.
