Utility model content
The purpose of this utility model is the deficiency overcoming prior art existence, there is provided a kind of waste-heat recovery device liner erosive velocity that can solve raw gas in coke oven coke oven uprising tube fast, oxidizable, heat exchange efficiency is low and unstable, regulate, the problem such as difficult in maintenance, make the upcast Riser waste heat recovery device for coke oven that can improve heat exchange efficiency that is efficient, gas recovery waste heat smoothly.
Realize the technical measures of above-mentioned purpose:
A kind of Riser waste heat recovery device for coke oven that can improve heat exchange efficiency, it is: its primarily of upper flange plate, lower flange, be connected to steel cylindrical shell between upper flange plate and lower flange, the cast bed of material, the glass glaze coating be located on the water-cooled tube in the cast bed of material, the annular water inlet pipe being located at steel cylindrical shell upper end, the annular rising pipe being located at steel cylindrical shell lower end, the prosopyle be located on annular water inlet pipe, the water inlet pipe be connected with prosopyle, the rising pipe be connected with posticum, mould material cylinder inboard wall of steel cylinder inboard wall form; Upper flange plate is set on annular water inlet pipe, and lower flange is set on annular rising pipe.
It is: on water inlet pipe and rising pipe, be separately installed with control valve.
It is: the water-cooled tube in the cast bed of material is snakelike or arc; The upper end of the water-cooled tube in the cast bed of material is connected with annular water inlet pipe and communicates, and the lower end of water-cooled tube is connected with annular rising pipe and communicates.
Feature of the present utility model: effectively can improve raw gas waste heat recovery efficiency in coke oven coke oven uprising tube, and heat exchange is stablized, in the coking later stage of reclaiming in raw gas waste heat or when postponing coke pushing, reduce at raw gas growing amount, when temperature is lower, pipe surface temperature can be avoided too low and cause tar steam catch a cold separate out and occur coking reaction; Once find that tube wall has corrosion phenomenon, ensure the safe operation of upcast by closing water inlet pipe; And also because whole upcast cylindrical shell is built into by refractory castable, intensity is high, not cracky, can available protecting heat transfer tube, improve the work-ing life of whole system.
