Problems solved by technology

[0002] At present, the coking industry generally adopts the traditional chamber-type coking equipment and process, which has long coking time, high dependence on strong coking coking coal, uneven coke quality at different positions in the carbonization chamber, and intermittent production leading to coke oven Disadvantages such as unorganized emissions and difficult to control during the process of coal charging and coking, and the production process of the coke oven is complicated, and the operation and maintenance of the four major vehicles are difficult

Embodiment 1

[0026] Embodiment 1: The continuous coking process is as follows.

[0027] 12% gas coal + 10% lean coal + 10% anthracite + 18% 1 / 3 coking coal + 10% fat coal + 36% coking coal + 4% asphalt binder, mix and crush, and the proportion of ≤3mm particle size is greater than 90 %, cold-pressed into briquettes with a diameter of 60mm by a press. The shaped coal is evenly distributed on the conveying device (9) of the continuous coking furnace through the shaped coal storage tank (6) in a single-layer distribution state; the conveying device (9) conveys the shaped coal along the conveying direction, and the conveying device The speed is 3mm / s. During the conveying process, the temperature of the combustion channels symmetrically arranged on the upper and lower surfaces of the conveying device is controlled to be 1250°C to heat the molded coal, so that the molded coal is gradually heated up during the conveying process, and the drying, softening, melting, and semi-coke solidification are ...

Embodiment 2

[0028] Embodiment 2: The continuous coking process is as follows.

[0029] 12% gas coal + 10% lean coal + 10% anthracite + 18% 1 / 3 coking coal + 12% fat coal + 38% coking coal, mixed and crushed, of which the proportion of ≤3mm particle size is greater than 90%, and hot pressed by a press into briquettes with a diameter of 60mm. The shaped coal is evenly distributed on the conveying device (9) of the continuous coking furnace through the shaped coal storage tank (6) in a single-layer distribution state; the conveying device (9) conveys the shaped coal along the conveying direction, and the conveying device The speed is 2.25mm / s. During the conveying process, the temperature of the combustion channels symmetrically arranged on the upper and lower surfaces of the conveying device is controlled to be 1150°C to heat the molded coal, so that the molded coal gradually heats up during the conveying process, and completes drying, softening, melting, and semi-coking. The coking proces...

Abstract

The invention discloses a continuous coking device and process. The continuous coking device comprises a continuous coking furnace (18); a high-temperature-resistant conveying device (9) is arranged in a furnace body of the continuous coking furnace (18) and used for conveying coal briquette; a plurality of heating devices are arranged around the conveying surface along the conveying direction ofthe conveying device (9) to heat the coal briquette on the conveying surface; a coal briquette storage tank (6) is arranged on the furnace body on the upper part of the operation front end of the conveying device (9), the upper part of the coal briquette storage tank (6) communicates with a coal briquette buffer tank (5), and the coal briquette buffer tank (5) communicates with a gas purificationsystem and a blow-down pipe through a pipeline and a fan; and a red coke storage tank (13) is arranged on the furnace body on the lower part of the operation rear end of the conveying device (9), a red coke buffer tank (14) communicates with the lower part of the red coke storage tank (13), and the red coke buffer tank (14) communicates with the gas purification system and the blow-down pipe through a pipeline and a fan. The device and the process have the characteristics of high coking speed, uniform coking, reliable process and the like.

Description

technical field [0001] The invention belongs to the technical field of coking, in particular to a continuous coking device and process. Background technique [0002] At present, the coking industry generally adopts the traditional chamber-type coking equipment and process, which has long coking time, high dependence on strong caking coking coal, uneven coke quality at different positions in the carbonization chamber, and intermittent production leading to coke oven Disadvantages such as unorganized emissions and difficult governance are generated during the process of coal charging and coking, and the production process of the coke oven is complicated, and the operation and maintenance of the four major vehicles are difficult. [0003] Under the increasingly severe situation of domestic environmental protection pressure, solve the problem that the traditional chamber coke oven cannot continue production and produce fugitive emissions, while reducing the coking time, improvin...
