A device and method for forming caking pulverized coal and producing dry distillation products

Abstract

The invention discloses a device and method for caking crushed coal molding and dry distillation product production. The device comprises a dry distillation molding reactor, left and right sides of the dry distillation molding reactor are provided with gas combustion heating chambers, a hollow channel with a bottom opening is arranged in the dry distillation molding reactor, the hollow channel is communicated with a dry distillation gas phase product discharge pipe, the device also comprises a coke pushing device, the coke pushing device is located at a mobilizable front side of the dry distillation molding reactor, and the coke pushing device can move along the hollow channel and is used for pushing molded semicoke in the dry distillation molding reactor. The device and method realize caking coal dry-distillation molding and high-yield production of a high-quality dry-distillation oil gas product, and solves the problem that the existing dry-distillation device such as a coke oven cannot simultaneously realize caking crushed coal dry-distillation molding and production of a high-yield high-quality oil gas product.

Description

technical field [0001] The invention belongs to the technical field of pulverized coal molding, in particular, the invention relates to a device and method for caking pulverized coal molding and dry distillation product production. Background technique [0002] Processes such as Lurgi gasifier, two-stage gasifier for industrial gas production, water gas generator, and calcium carbide production furnace all require large-grain coal or lump coal with a particle size larger than a certain size, and have no or very low caking properties . For example, two-stage gasifiers and water gas generators for industrial gas production require coal or semi-coke raw materials larger than 15mm. On the other hand, in the coal production process, the output of such large-sized lump coal is low, and the proportion of lump coal mined by machines is difficult to exceed 30%. Therefore, the industrial gas and water gas industries are facing a serious shortage of lump coal resources. Therefore, i...
