Thermal-state replaceable pool wall structure and replacement method thereof

Abstract

The invention provides a thermal-state replaceable pool wall structure and a replacement method thereof. The pool wall structure comprises a contact layer, a backing layer, a heat preservation layer and a temperature monitoring device which are sequentially arranged, wherein the top surface of the backing layer is lower than the top surface of the contact layer, the top surface of the heat preservation layer is lower than the top surface of the backing layer, the detection end of the temperature detection device is located in the contact layer, the backing layer comprises an upper backing and a lower backing which are sequentially distributed from top to bottom, the top surface of the upper backing is higher than the top surface of the heat preservation layer and lower than the top surface of the contact layer, and the top surface of the lower backing is lower than the top surface of the heat preservation layer. The pool wall structure of the scheme can be replaced in a hot state under the condition that production is not stopped, and the heights of the contact layer, the backing layer and the heat preservation layer are gradually reduced, so that the heat dissipation area of the pool wall structure is increased, the heat dissipation efficiency of the pool wall is improved, and the erosion speed is reduced.

Description

technical field [0001] The present application relates to the technical field of tank kilns, in particular to a thermally replaceable tank wall structure and a replacement method thereof. Background technique [0002] The traditional glass tank kiln uses a burner installed on the breast wall to melt the glass. Generally, the erosion of the tank wall bricks is mainly in the part below the liquid level. The pool wall structure is usually divided into a contact layer, a backing layer and an insulation layer that are in direct contact with the molten glass. Among them, the contact layer and the backing layer are an integral structure, and the liquid surface is located in the middle of the pool wall brick, that is, the pool on the upper and lower layers of the liquid surface. The wall brick is a whole. [0003] With the scouring of high-temperature glass liquid and the high-temperature oxygen-enriched combustion of burners installed on the top of the bridge, the exposed part of ...

Problems solved by technology

[0003] With the scouring of high-temperature glass liquid and the high-temperature oxygen-enriched combustion of the burner installed on the top of the bridge, the part of the pool wall brick exposed in the space (above the liquid level) is severely eroded, and what is more, after a period of erosion, The pool wall brick exposed in the space (above the liquid level) will evaporate and disappear, seriously affecting the normal operation and operation of the kiln

[0004] Due to the change of the current kiln combustion method, the eroded part of the pool wall brick is transferred from below the liquid surface to above the liquid surface (exposed in the space part), and the erosion of the part below the liquid surface can be repaired by conventional operations (in the eroded pool wall However, for the erosion of the part above the liquid level, the use of tiling can only temporarily alleviate the erosion of this part. The liquid level is in the middle of the three-phase interface and the pool wall bricks, which is the most serious pool wall erosion. The pool wall brick at the liquid level is an integral structure, which is difficult to replace, and it is difficult to replace it in a hot state. If the conventional method of tiling outside the liquid level of the pool wall brick is adopted, there are strict restrictions on the thickness of the tiling. restrictions, and this method can only temporarily alleviate the erosion problem of the exposed part of the pool wall in the space, but cannot completely solve the problem
