Problems solved by technology

[0005] In order to solve the above problems, the object of the present invention is to provide a method and a roof structure for improving the airtightness of the coke oven roof. The coke oven roof is divided into upper and lower layers. A sliding layer is set; this structure and method can effectively solve the situation that the upper part of the coke oven roof is damaged by the joint expansion of the lower part of the furnace roof due to the uneven expansion of the upper part of the coke oven roof and the lower part of the furnace roof

Embodiment Construction

[0014] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0015] See figure 1 , a coke oven roof structure, the coke oven roof is divided into two parts: the upper part of the furnace roof 1 and the lower part of the furnace roof 2, the upper part of the furnace roof is built with clay bricks, and the lower part of the furnace roof is built with silica bricks. The upper part 1 of the furnace roof and the lower part 2 of the furnace roof are respectively built as an independent whole, and there is no brick groove tongue between the upper part 1 of the furnace roof and the lower part 2 of the furnace roof, and a sliding layer 3 is provided; the sliding layer 3 can be a graphite layer, Slide the grease layer, etc. At the burner head position, a grouting hole 4 is provided on the upper part of the furnace roof 1 , and the upper part of the furnace roof is close to the burner head protection device 5 . A la...

Abstract

The invention relates to a method for increasing air tightness of a coke oven top and an oven top structure. The coke oven top is divided into two structures of an oven top upper portion and an oven top lower portion, wherein the oven top upper portion and the oven top lower portion are respectively built as independent whole bodies, and a sliding layer is arranged between the oven top upper portion and the oven top lower portion; when an oven is dried, after the over top upper portion and the oven top lower portion are respectively swelled, mortars are grouted via a grouting hole on the oven top upper portion to fill a top gap on the oven top upper portion and a gap between the oven top lower portion and a big protective plate so as to prevent mutual leakage between adjacent carbonization chambers and assure the leakproofness of the coke oven. The invention has the advantages that the situation that the oven top upper portion is swelled together with the oven top lower portion to cause damages due to non-uniform swelling at the oven top upper portion and the oven top lower portion of the coke oven can be effectively solved.

Description

technical field [0001] The invention relates to the field of coke ovens, in particular to a method for improving the airtightness of a coke oven roof and a coke oven roof structure. Background technique [0002] At present, coke ovens at home and abroad generally have an integrated roof structure, that is, bricks on each layer of the roof part are interlocked with brick grooves and tongues, and there is no relative sliding between the upper and lower layers. The roof masonry of the coke oven is divided into two stages. The first stage is that the roof part except the furnace head is integrally built along with the coke oven body. After the gap between the head and the large protective plate is grouted, the furnace head part of the furnace top is masonry. Because the first masonry part has passed through the oven expansion, the rear masonry part has not yet expanded, so that there are irregular gaps between the first masonry part and the rear masonry part of the furnace roof...
