specific Embodiment approach 2

[0055] Specific implementation scheme two, for the purpose of producing gasified coal gas, the device combination of this scheme is the main tower and the main tower, see the attached Figure 4 .

[0056] in the attached Figure 4 As shown, the figure shows a combination schematic diagram of the main tower and the main tower of the powder low-temperature carbonization gasification device of the present invention. The main towers are arranged side by side with the main towers, and the top air collection chamber a and the feed bin c of the four main towers are connected to each other. A pyrolysis water vapor chamber G and a low-temperature carbonization gas chamber H are installed in the dry distillation section of the main tower.

[0057] The powder is transported into the powder inlet c3 of the four main tower feeding chambers Ic by dense-phase air flow of inert gas, and the material and gas are separated by the bag filter c2, and the gas is discharged through the inert gas ...

Abstract

The invention discloses a low-temperature dry distillation and gasification device for powder. The device is formed by combining one or more units with the same function or different functions, wherein each unit which can be used independently is taken as a main tower, and each unit which can realize functions by the aid of the main tower is taken as an auxiliary tower. According to the low-temperature dry distillation and gasification device for the powder, gas products such as pyrolytic vapor generated during drying of the powder, low-temperature dry distillation gas, gas produced by a gasifier and the like produced at different stages can be classified and guided out, and solid products are semicoke and ash residues. The technical problem about quality-based utilization of the powder is solved, and meanwhile, the unit energy consumption of the products is effectively reduced.

Description

technical field [0001] The invention relates to the fields of coal chemical industry and coal gasification, and in particular provides a powder low-temperature dry distillation gasification device. Background technique [0002] Coal quality utilization is mainly composed of four parts: coal pyrolysis upgrading, gas purification and utilization, coal tar deep processing and clean coal conversion. Coal gasification technology is the key technology for the utilization of coal by quality. It is mainly composed of three parts: coal preparation technology, gasification furnace technology, and post-gasification process technology. The core is gasification furnace technology. Gasification technologies emerge in endlessly. From a large-scale analysis, there are three major categories: fixed (moving) bed gasification, fluidized bed gasification and entrained bed gasification. [0003] The low-temperature carbonization technology of coal is widely used. In industrial production, the l...
