Sufficient combustion coal chemical industry gasification furnace slag decarburization device

Abstract

The invention discloses a sufficient combustion coal chemical industry gasification furnace slag decarburization device. The sufficient combustion coal chemical industry gasification furnace slag decarburization device comprises a first water inlet pipe, a gasification furnace, flame spraying ports and a vibration motor. The first water inlet pipe is arranged on the left side of a coal mill, and a coal inlet pipe is arranged below the first water inlet pipe. The gasification furnace is in sealed connection to the right side of the coal mill through a feeding pipe. The lower end of a screening device is in sealed connection with the coal inlet pipe through a fine slag conveying device. The flame spraying ports are formed in the gasification furnace. The vibration motor is arranged on the left side of the screening device, a screen is arranged in the screening device, the upper portion of a condensation device is connected with the first water inlet pipe through a backflow pipe, and the lower portion of the condensation device is connected with a second water inlet pipe. According to the sufficient combustion coal chemical industry gasification furnace slag decarburization device, the gasification furnace is provided with the flame spraying ports which are arranged into double layers, the function of sufficient combustion of pulverized coal is achieved, and the decarburization efficiency of the sufficient combustion coal chemical industry gasification furnace slag decarburization device can be better improved.

Description

technical field [0001] The invention relates to the technical field of slag decarburization, in particular to a fully combusted coal chemical gasification slag decarburization device. Background technique [0002] Due to the large production capacity of the coal-water slurry gasifier, the corresponding amount of coarse slag and fine ash produced is also relatively large. The carbon content of the coarse slag of the gasifier is less than 10%, and the calorific value is less than 500 kcal. It is mainly used for construction and Cement industry; while the carbon content of fine ash is high, between 20-25%, and the calorific value is between 1300-1600 kcal, which has a high combustion value. If fine ash is used in construction and cement industries , In the process of storage and transportation, it not only occupies a large area of ​​land, but also pollutes the environment, resulting in a serious waste of resources. [0003] However, the existing slag decarburization device doe...
