Abstract
The invention relates to a novel double-chamber kiln jetting system mainly applicable to jetting of coal powder for a double-chamber kiln. The double-chamber kiln jetting system is mainly composed of a manual gate valve, dome valves, flexible joints, a jetting tank inlet dome valve, a jetting tank, vertical rotary feeding machines, a weighing device, a level gage, pressure transmitters, a fluidization device, conveying pipelines, a wear-resisting bend, distributors, a MCC control cabinet, a PLC control cabinet, an upper computer and the like. The bottom of each jetting device is provided with two vertical metering rotary feeding machines, the outlet of each feeding machine is connected with one main conveying pipeline, the conveying pipelines are provided with pipeline switching valves, each main pipeline on a kiln body platform is divided into two braches, each branch pipe corresponds to one distributor, and coal powder are jet by the distributors into 33 spry guns corresponding to kiln chambers. The system has the advantages that the jetting precision is high, and jetting is stable and will not be affected by changes of material characteristics and fluctuation of pressure in a kiln; due to the unique vertical rotary feeding structure design, it is ensured that the coal spraying system is smooth and free of fluctuation, it is ensured that coil powder is evenly and stably jet in the pipeline and free of blockage; and variable-frequency speed-control continuous quantitative feeding can be achieved, and the feeding amount can be automatically adjusted on line.
Description
technical field [0001] The invention relates to a novel injection system for a double-chamber kiln, which is mainly applicable to the injection of pulverized coal in a double-chamber kiln. Background technique [0002] Each double-chamber kiln has two kiln chambers, and each kiln chamber has 33 coal injection ports. The double-chamber kiln uses fluid fuels, such as gas, oil, coal powder, etc. Combustion-supporting air is fed from the upper part of the shaft kiln by a Roots blower, and the combustion-supporting air is preheated in the preheating zone before being mixed with fuel, and then the combustion flame flow passes through the calcination zone and co-flows with the ore to calcine the ore. The design of traditional pulverized coal injection main pulverized coal bin, screw distribution conveyor, metering screw and pulverized coal injection device. The injection volume is controlled by adjusting the gas volume. The disadvantage of this process is that it is easy to cause...
