Abstract

The invention relates to a non-equidirectional expansion membrane wall angle joint seal device, and relates to a membrane wall seal device, and the device is used for solving the problem of poor seal performance of a hearth because a front membrane water cooling wall and two side membrane water cooling walls of the existing boiler hearth have different expansion amount at high temperature, thus the welding lines of the front membrane wall cooling wall and two side membrane water cooling walls are disconnected. The device is positioned at the external part of two corners of the front side membrane water cooling wall of the boiler hearth, and comprises a plurality of steel connection pieces, namely a first steel connection piece, a second steel connection piece, a third steel connection piece, a fourth steel connection piece, a fifth steel connection piece and a sixth steel connection piece; a first empty cavity is defined by the first steel connection piece, the second steel connection piece, the third steel connection piece, a side membrane water cooling wall which is adjacent to the second steel connection piece in the two side membrane water cooling walls and the front membrane water cooling wall of the boiler hearth; and one end of the sixth steel connection piece is fixedly connected with the front membrane water cooling wall of the boiler hearth. The seal device provided by the invention is used for the seal of the boiler hearth.

Description

technical field [0001] The invention relates to a membrane wall seal. Background technique [0002] The existing membrane water cooling wall at the front of the boiler furnace and the membrane water cooling walls on both sides of the boiler furnace are respectively connected by welding. However, during the operation of the boiler, due to the front membrane water cooling wall and the two side membrane water cooling The expansion of the wall is different at high temperature, so that the corresponding welds are disengaged, causing the furnace to be not tightly sealed, and a large amount of cold air leaks into the furnace, which destroys the combustion conditions of the furnace and seriously affects the normal operation of the boiler. Contents of the invention [0003] The purpose of the present invention is to solve the existing boiler furnace front membrane water cooling wall and the two side membrane water cooling walls of the boiler furnace due to the difference in expansi...
