Abstract

The invention provides an electrical heating continuous coal pyrogenation coking furnace which includes a furnace body, the furnace body is equipped with a hopper, a pre-heating segment, an electrical heating main body segment, a gas cycle cooling segment and a coke discharge segment orderly from upper to down; control valves are set among the hopper, the pre-heating segment, the electrical heating main body segment, the gas cycle cooling segment and the coke discharge segment. The coking furnace has advantages as follows: 1. the furnace can control rolling speed and heating effect of moulded coal efficiently in rolling process of coking coal; 2. the furnace solves temperature and environment atmosphere required by the coal pyrogenation coking; 3. the furnace changes traditional coke cooling method by water into inert gas cycle for realizing heat energy utilizing fully, is energy-saving and environmental-friendly; 4. the furnace reduces raw material cost, increases coke quality and reduces coke foam and coke particle generating; 5. the furnace can replace full coal gas by electrical heating which can solve smoke pollution efficiently.

Description

technical field [0001] The invention relates to a coking method and equipment thereof, in particular to an electric heating continuous coal pyrolysis coking method and a coking furnace thereof. Background technique [0002] 1. Principle of coking [0003] In coking production, the basic raw material is coking coal, which is heated at high temperature in a closed coking furnace in isolation from air, releasing moisture and adsorbed gas, and then decomposing to produce gas and tar, etc., leaving coke with carbon as the main body. This process of coal pyrolysis is commonly referred to as carbonization of coal. [0004] Coal dry distillation is divided into three types: low temperature dry distillation, medium temperature dry distillation and high temperature dry distillation. The main difference between them is the final temperature of carbonization. Low-temperature carbonization is 500°C-600°C, medium-temperature carbonization is 700°C-800°C, and high-temperature carbonizati...
