Abstract

The invention provides a pyrolysis apparatus and pyrolysis equipment for coal and relates to pyrolysis processes for the coal. The pyrolysis apparatus and the pyrolysis equipment are used for solving the problem that the dust content of gas is high due to the fact that coal-pyrolysis fluidized gas and the coal are directly heated. The pyrolysis apparatus for the coal comprises a shell body, at least one heating tube and a fluidized gas distributing plate, wherein the shell body forms an encircled chamber, and the chamber is provided with a first opening and a second opening which are opposite to each other; the heating tubes are located in the chamber; and the fluidized gas distributing plate is located at the first opening of the chamber, and a plurality of through holes are formed in the fluidized gas distributing plate and are used for enabling the fluidized gas and coal dust to flow to the other side of the fluidized gas distributing plate from one side of the fluidized gas distributing plate. The pyrolysis apparatus for the coal is applied to the pyrolysis equipment for the coal.

Description

technical field [0001] The invention relates to a coal pyrolysis process, in particular to a coal pyrolysis device and pyrolysis equipment. Background technique [0002] my country is rich in coal resources, while oil and natural gas resources are relatively scarce. Therefore, it is of great significance to use relatively abundant coal resources to produce alternative oil products, chemical products and gas to relieve my country's pressure on oil and natural gas. In the world, low-rank coal represented by lignite and long flame coal accounts for a large proportion. In today's energy-constrained world, how to improve the processing, transformation and comprehensive utilization of coal has become the focus of attention. [0003] figure 1 Shown is an existing fluidized bed classification coal pyrolysis equipment, including a pyrolysis chamber composed of a low temperature pyrolysis chamber 14 and a high temperature pyrolysis chamber 4, a partition wall 5, a pyrolysis gas waste...
