Problems solved by technology

In order to improve the working environment of the furnace top, some coke ovens have undergone roof renovation, and tried to use some refractory materials with relatively good heat insulation performance. After the completion of the implementation, the temperature of the furnace top surface dropped to a certain extent in a short time, but it did not The operating environment of the furnace roof has not been fundamentally changed. If the coke oven area is further closed, it will be difficult to ensure safe and stable coke oven production and operation

Embodiment Construction

[0034] see figure 1 , figure 2 , the method for improving the environment of the coke oven roof region of the present invention, the coke oven roof 10 faces along the tie ditch on both sides of the coal inlet 20 to set the tie ditch air duct 1, 1 ', and the two tie ditch air A number of connecting air passages 2 and 2' are arranged between the passages 1 and 1' to connect; the coke side of the coke oven roof 1 and the machine side are respectively provided with an air supply system 3 and a hot air collection system 4; wherein,

[0035]The air supply system 3 includes a blower 31, a cold air duct 32, a flow orifice on the coke side or an opening adjustment valve 33; 1. One end is connected to the cold air duct 32 through the coke-side connecting duct 34, and the air is supplied by the blower 31 to ensure that the air maintains positive pressure circulation in the air channel 1 and the connecting air channel 2 of the furnace top surface; the coke-side flow orifice plate Or th...

Abstract

According to a method for improving the environment of the furnace top area of a coke oven, brace groove air ducts are arranged on the furnace top surface of the coke oven along brace grooves in the two sides of a coal feeding opening, and a plurality of communicating air ducts are arranged between the two brace groove air ducts for connection; and an air supply system and a hot air collection system are arranged on the coke side and the machine side of the coke oven top respectively. By designing air flow guide of the furnace top area, absorbing air and blocking heat loss of the furnace top area, continuous air renewal of the furnace top area can be achieved under the condition that the furnace top area is closed, and finally the working environment of the furnace top area is improved.

Description

technical field [0001] The invention belongs to the technical field of coke oven energy saving and environmental protection, and in particular relates to a method for improving the environment of the top area of ​​the coke oven. Background technique [0002] There are many types of coke ovens, including conventional mechanical coke ovens, heat recovery coke ovens, and semi-coke (semi-coke) carbonization furnaces, of which conventional mechanical coke ovens account for the vast majority. Coke oven smelting is the process of high-temperature dry distillation of coking coal in the coke oven carbonization chamber, which is isolated from air. Usually, the temperature in the furnace is as high as 1200-1350 °C. Due to the characteristics of coking production and coke oven structure, the surface temperature of the coke oven top is relatively high, generally exceeding 70°C, sometimes as high as 100°C, and the heat dissipation from the top of the coke oven accounts for more than 8% of...
