Abstract

The invention discloses a U-Gas gasification furnace fly ash continuous return control system and method, which comprises a fly ash filtration collection and discharge device connected to a gas ash separation and storage device through a high-efficiency cyclone conveying pipe. The discharge device is connected to the gasifier device through the auxiliary gas source pipeline system, and the gasifier device is connected with a protective gas delivery pipeline; Value detection monitoring detection system. The system achieves continuous powder return by controlling the powder return of the gasifier, maintains the bed layer of the fluidized bed gasifier, stabilizes the operation of the coal feeding system, and then stabilizes the working condition of the gasifier, minimizes the consumption of raw coal, and greatly reduces It reduces the production cost of the enterprise, and at the same time greatly improves the on-site environment, creating conditions for the green development of the enterprise.

Description

technical field [0001] The invention relates to the technical field of coal gasification, and relates to a U-GAS fluidized bed gasification furnace fly ash continuous return control system and a control method thereof. Background technique [0002] The u-gas gasifier belongs to the fluidized bed gasification furnace, which adopts the dry ceramic dedusting method. At present, the maximum pressure of the production device is 1.0Mpa. Humidification is discharged on-site and transported; because the carbon content of the fly ash produced by the gasifier is as high as 40% to 60%, and the particle size is relatively fine (average particle size is about 30 μm), the dust is relatively large during the humidification process using a humidifier. If a closed tanker is used During loading and unloading, the dust is even greater, seriously polluting the site environment. The fly ash produced by the U-gas gasifier accounts for about 10% of the raw materials. If this part of the fly ash c...
