Novel heat insulation structure of coke oven foundation top plate

Abstract

The invention relates to a novel heat insulation structure of a coke oven foundation top plate. The novel heat insulation structure comprises an integral castable layer, transverse preformed holes andlongitudinal preformed holes. Side beams are arranged on the two sides of a foundation top plate, and the top faces of the side beams are higher than the top face of the foundation top plate, so thata groove structure is formed in the top of the foundation top plate. The integral castable layer is arranged in a groove structure; the integral castable layer is provided with at least one layer oftransverse preformed holes and at least one layer of longitudinal preformed holes, and each of the transverse preformed holes and the longitudinal preformed holes includes a plurality of preformed holes formed in parallel. The refractory castable layer is adopted to replace a traditional refractory brick masonry structure, and a protective layer is formed on the coke oven foundation top plate in apouring mode; in the pouring process, holes are reserved through pre-buried plastic pipes, and the longitudinally and transversely arranged hole structures can play a good role in heat insulation, sothat the temperature of foundation top plate concrete is reduced, and the service life of the foundation top plate concrete is prolonged; meanwhile, the coke oven basement temperature is reduced, andcoke oven operation conditions are improved.

Description

technical field [0001] The invention relates to the technical field of coke oven masonry, in particular to a novel heat insulation structure of a coke oven foundation roof. Background technique [0002] The structure of modern coke oven consists of four parts from bottom to top: regenerator, chute, combustion chamber and furnace roof. The coke oven body is made of refractory bricks, and is built on the top plate of the coke oven foundation poured by concrete. During the coking process of the coke oven, the furnace coal is heated to about 1000°C in the carbonization chamber to make coke. The heat required for heating is provided by the combustion of gas in the combustion chamber, and the heated waste gas is pumped out of the coke oven. When the exhaust gas enters the chimney through the regenerator, small flue, and flue, although its temperature gradually decreases, it will still transfer a large amount of heat to the concrete structure such as the foundation roof, the flue ...

AI Technical Summary

Problems solved by technology

In the process of laying these refractory bricks, masonry workers need to use fire clay to build them, which is cumbersome and time-consuming; and the price of refractory bricks is relatively high, but the cost performance is not high
