Abstract

The invention discloses a pulverized coal pressurized fluidization conveying device which comprises a taper barrel and a fluidization element installed inside the taper barrel coaxially. The fluidization element is of a taper structure and comprises a fluidization area. A wall at the fluidization area comprises a porous inner reinforcing barrel on the inner layer, and multi-layer composite sintering metal felt fixed to the outer surface of the porous inner reinforcing barrel. A plurality of through holes are distributed in the porous inner reinforcing barrel. The inner layer and the outer layer of the multi-layer composite sintering metal felt are both precision screens. The taper barrel is provided with two inert gas inlets symmetrically, and the inert gas inlets are opposite to the fluidization area of the fluidization element. According to the pulverized coal pressurized fluidization conveying device, online fluidization of pulverized coal is achieved, fluidization is conducted in the conveying process of pulverized coal, fluidizing gas provides pressure for conveying of the pulverized coal at the same time, the structure of a pneumatic conveying system is simplified, and the fluidization effect is improved. Besides, the structure of the fluidization device is modified, and the problems of pipeline blockage and supply interruption of the pulverized coal are solved.

Description

technical field [0001] The invention specifically relates to a pulverized coal pressurized fluidized conveying device. Background technique [0002] In the pulverized coal gasification plant, the pulverized coal needs to be conveyed pneumatically. The existing method of pneumatic conveying is to send the pulverized coal from the atmospheric pressure chamber to the high-pressure cylindrical pulverized coal chamber via the variable pressure chamber. When the pulverized coal material in the high-pressure pulverized coal bin reaches the high material level, stop feeding. According to the amount of pulverized coal required by the gasifier and the number of nozzles put into operation, the corresponding air volume control valve of the fluidizing air duct and the corresponding discharge control valve are opened, and the fluidizing air enters each independent air chamber through the fluidizing air duct and passes through the cloth The wind plate fluidizes the pulverized coal in the...
