Masonry method for secondary air inlet of heat recovery coke oven

Abstract

The invention relates to a method for building a secondary air inlet of a heat recovery coke oven, which comprises the following steps of: 1, building an air inlet bottom; 2, building masonries at twosides of the air inlet to form a long groove body; 3, placing a mortar vibrator in the long groove body, wherein the mortar vibrator comprises a hollow rectangular structure consisting of four angledies, the adjacent edges between the angle dies are connected through the elastic pieces, a vibration mechanism is arranged in the rectangular structure, the appearance structure of the vibration mechanism is matched with the space of the hollow rectangular structure, the vibration mechanism is arranged in the space of the hollow rectangular structure, and the hollow rectangular structure is expanded and matched with the cross section size of the air inlet, so that the air inlet can be easily filled to prevent the masonry mortar from overflowing; 4, building an air inlet cover plate brick at the upper end of the long groove body, and discharging the air of the slurry through the mortar vibrator during building, so that the built mortar is full and meets the elevation requirement simultaneously. According to the method for building a secondary air inlet of a heat recovery coke oven, the mold is adopted to fill the air inlet, so that the mortar is prevented from overflowing, and when thecover plate brick of the air inlet is built, the mortar is full and the mortar is free from omission and bubbles.

Description

technical field [0001] The invention relates to the technical field of kiln construction, in particular to a method for building a secondary air inlet of a heat recovery coke oven. Background technique [0002] Clean heat recovery coke oven refers to a kind of coke that the coke oven gas, chemical products and other harmful substances produced in the coking process of coking coal are fully and reasonably burned inside the coke oven, and the heat of high-temperature waste gas is recovered to generate electricity. furnace. During the coking process, the coke oven is fed with an appropriate amount of air to burn all the gas generated in the furnace to heat the coal for coking. The secondary air inlet (such as figure 1 As shown) is located at the bottom of the coke oven, about 15 meters long, and the space is small. During the masonry process, the mortar extruded from the secondary air inlet is easy to miss the bottom of the air inlet, and there is also grout between the brick...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a heat recovery coke oven secondary air inlet masonry method for the deficiencies in the above-mentioned prior art. The method of rubbing the bricks back and forth ensures that when the air inlet cover bricks are built, the mortar joints are full, the mortar is not missing, and there is no air bubble, which avoids the mortar squeezed out of the air inlet cover bricks and the omission of the mortar between the brick joints At the bottom of the air inlet, further causing the problem of dirty and clogged secondary air inlet
