Embodiment Construction

[0010] A clean heat recovery coke oven door, comprising an upper furnace door 1, a lower furnace door 2, an upper protection plate 9, a middle protection plate 10, a lower protection plate 11, the upper furnace door 1 is provided with an upper protection plate 9, a lower Both sides of the furnace door 2 are provided with a middle protective plate 10, and the lower furnace door 2 is provided with a lower protective plate 11. The lower edge of the upper furnace door 1 that is higher than the upper protective plate 9 and wider than the width of the carbonization chamber is changed to a The lower edge of the carbonization chamber is as long as the width, and the height of the lower edge is lowered to be parallel to the upper protection plate 9, which lays the foundation for the sealing of the upper and lower furnace doors. Circular groove 4, the asbestos round rope is stuck inside with an adhesive, and half of the protruding asbestos rope is in plane contact with the upper protecti...

Abstract

The invention relates to a clean heat recovery coke oven door, which comprises an upper oven door 1, a lower oven door 2, an upper guard plate 9, intermediate guard plates 10 and a lower guard plate 11, wherein, the upper guard plate 9 is arranged on the upper oven door 1; both sides of the lower oven door 2 are provided with the intermediate guard plates 10; the lower guard plate 11 is arranged under the lower oven door 2; the width of the lower edge of the upper oven door 1 is equal to the width of a carbonization chamber; the height of the lower edge of the upper oven door 1 is parallel tothe upper guard plate 9; an upper segmental arc 3 is arranged on the upper edge of the upper oven door 1; a semicircular groove 4 is arranged on the upper segmental arc 3; a braided asbestos round packing is arranged inside the semicircular groove 4; the lower oven door 2 consists of an oven door body 5 and four detachable cast iron bars 6 provided with dovetail grooves 7; and flat ceramic fiber ropers are arranged inside the dovetail grooves 7. The clean heat recovery coke oven door changes the sealing form of the oven door from rigid surface contact to flexible seal, solves the problems of unprecise seal and inorganized air inlet of a coke oven during the coking process, reduces the coke rate, improves the overall coke yield, and reduces the resource waste.

Description

1. Technical field [0001] The invention belongs to a coke oven door, in particular to a clean heat recovery coke oven door. 2. Background technology: [0002] At present, environmental protection requirements at home and abroad have been improved. In 2000, Shanxi Chemical Design Institute independently developed the QRD-2000 clean heat recovery tamping coke oven with better environmental protection effect. From 2000 to now, there are more than 80 clean heat recovery tamping coke ovens built at home and abroad. However, due to the negative pressure operation of this furnace type, the furnace door sealing requirements are strict, and this technology is a new thing. The new technology is not very mature, and the furnace door has always been sealed with a rigid hard seal. The sealing effect is poor, and there has been a problem of serious coking due to the large amount of unorganized air intake from the furnace door, resulting in a waste of resources and a reduction in the econo...
