Problems solved by technology

[0004] The existing technology has the following problems: the structure of the existing coke ovens for producing molded coke from anthracite can only be heated from the top and the bottom, which may easily cause temperature deviations on the sides, resulting in a decrease in coking quality. At the same time, the coke ovens cannot be preheated. Reduce coking efficiency

Embodiment approach

[0026] As an embodiment of the present invention, the lower end of the guide column 12 is fixedly connected with a heat conduction plate 18; the heat conduction plate 18 is inserted into the middle of the U-shaped groove 13 and designed, and the heat conduction plate 18 is made of heat conducting material; A diaphragm 19 is fixedly connected between one end surface in the heat box 1 and the inner wall of the heat collecting box 1; the diaphragm 19 is insulated and made of elastic material, and the diaphragm 19 is designed to be close to the lower surface of the partition plate 17 in the initial state; when working, The contact area between water and heat can be increased through the heat conduction plate 18, thereby increasing the production rate of water vapor and further increasing the preheating rate of the coal to be coked in advance. At the same time, the setting of the diaphragm 19 can ensure the air pressure in the upper and lower heat collecting box 1 of the diaphragm 19...

Abstract

The invention belongs to the technical field of coking ovens, and specifically relates to a coking oven for producing molded coke from anthracite, which includes a heat collecting box, a carbonization chamber and a side adjustment assembly, the upper end of the carbonization chamber is provided with a furnace roof, and the carbonization The lower end of the chamber is provided with a combustion chamber top cover, the lower end of the combustion chamber top cover is provided with a primer channel, the bottom of the primer channel is provided with an air inlet, and the two sides of the carbonization chamber are provided with vertical fire channels; The vertical fire channel is equipped with a side adjustment assembly, by turning the fire pipe to a suitable angle, the fire pipe can heat the side of the anthracite coal, so that the temperature of the side can be heated quickly and uniformly, so as to speed up the coking efficiency and improve the quality; The heat collection box at the upper end of the vertical fire path collects heat. When the next heating is performed, the control valve of the preheating pipeline is opened to preheat the coal to be coked in the carbonization chamber in advance, which is convenient for coking. The structure is simple and portable.

Description

technical field [0001] The invention belongs to the technical field of coking ovens, in particular to a coking oven for producing molded coke from anthracite. Background technique [0002] A coke oven is a furnace used to extract coke. A modern coke oven consists of a carbonization chamber, a combustion chamber, a regenerator, a chute area, a roof, a foundation, and a flue. The coal material in the carbonization chamber is heated and turned into coke under the condition of air isolation. The age of a coke oven is generally about 25 years, and it can reach more than 30 years under good operation and maintenance. The types of modern coke ovens can be divided in many ways. The main differences of coke ovens with different structures lie in the following aspects: the structure of the combustion chamber, the adaptability to the type of heating gas, the way of heating gas supply, and the regenerator. The layout and measures to improve the uniformity of high-level heating, etc. ...
