Molded coal continuous gasification fixed bed coke charging powder exhaust metering control system

Abstract

The invention relates to a coke-charging powder-discharging metering control system for a fixed bed for continuous briquette gasification, which consists of a large bunker, a pressure-reducing chute, a powder discharge chute and a feeding chute, wherein an upper feeding machine, a weighing bunker, a lower feeding machine and a weighing supporting frame are also arranged below the large bunker; the large bunker is positioned above the upper feeding machine, the pressure-reducing chute is connected below the large bunker, the upper feeding machine and the pressure-reducing chute are connected in a flexible connection mode, and the weighing bunker is arranged at a discharge outlet below the upper feeding machine; a powder screening device is arranged in a silo, and is connected with the lower feeding machine below the weighing bunker in a flexible connection mode; and the weighing bunker is supported on the weighing supporting frame. The system is provided with the powder screening device, a powder discharge device and a weighing device, and can basically prevent powder coal from entering a gas-making furnace, thereby improving the production efficiency and the yield of coal gas; on the other hand, the recollected powder coal can also be recycled, which satisfies the national industrial policy of recycling economy, energy conservation and emission reduction, and greatly improves the benefit of enterprises.

Description

Technical field: [0001] The invention relates to a metering control system for continuous gasification of molded coal in a fixed bed adding coke and powder discharge. Background technique: [0002] In the existing coal oxygen-enriched continuous gas-making furnace, since the raw coal has not passed through the pulverized coal screening process, the old raw raw coal entering the furnace body contains both molded coal and pulverized coal, and the pulverized coal entering the gas-making furnace will have a negative impact on the gas. The production has a serious negative impact, seriously affecting the gas production, and it will block the gas outlet pipeline, generate a large amount of dust and cause pollution emissions, and this kind of furnace body can not achieve the balance between the amount of coal input into the gas furnace and the gas production of the gas production. Without accurate measurement, it is impossible to find out the defects of the production process in a ...
