Description

Technical Field

[0001] This utility model relates to the field of coke oven technology, and in particular to a sealing structure for connecting the coke oven flue and the resisting wall. Background Technology

[0002] In conventional coke ovens, the flue gas ducts are located on both sides of the coke oven in the basement. The ducts connect to the main flue gas duct at the oven end and then flow into the base of the chimney. The flue gas temperature inside the duct is approximately 300℃. Heat recovery coke ovens are divided into horizontal and vertical types. In horizontal heat recovery coke ovens, the flue gas duct is located at the top of the oven, while in vertical heat recovery coke ovens, the flue gas duct is located at the bottom. The flue gas temperature inside the heat recovery coke oven flue gas duct can reach approximately 800℃.

[0003] After exiting the resistance wall, the vertical heat recovery coke oven generally flows through a branch flue to the main flue. Due to the influence of flue gas temperature, the refractory material at the connection between the inner and outer parts of the resistance wall is prone to uneven expansion, which can lead to the refractory material falling off at the connection and seriously affect the normal production of the coke oven. Utility Model Content

[0004] The purpose of this invention is to provide a sealing structure for the connection between the coke oven flue and the resisting wall, thereby solving the problems existing in the prior art. This structure effectively absorbs the expansion displacement of the resisting wall and the flue, increasing their stability. High-temperature resistant materials are used to fill the gaps in the socket joint, increasing the sealing performance of the flue system.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides a sealing structure for connecting a coke oven flue and a resisting wall. The resisting wall protrudes from the flue gas outlet at the furnace end to form an insertion port. The flue gas inlet end of the branch flue is inserted into the insertion port to form a socket structure. The connection between the resisting wall and the branch flue is filled with a high-temperature resistant sealing structure.

[0007] Preferably, multiple flues are provided, and each flue is connected to the resisting wall via a socket structure.

[0008] Preferably, the number of the flues is 2, 4, or 6.

[0009] Preferably, the ends of the branch flues merge and connect to the main flue.

[0010] Preferably, both the branch flue and the main flue are constructed of refractory materials.

[0011] The present invention achieves the following technical advantages over the prior art:

[0012] The sealing structure connecting the coke oven flue and the resisting wall in this utility model uses a socket connection to divide the flue and the resisting wall into two parts. High-temperature resistant sealing material is used to fill the socket connection area. This connection structure is easy to construct and provides good sealing at the joint. It effectively absorbs the expansion displacement of the resisting wall and the flue, increasing their stability. The use of high-temperature resistant material to fill the gaps in the socket area further enhances the sealing performance of the flue system. Attached Figure Description
