Description

A kind of dry quenching furnace shell of novel texture
Technical field
The utility model relates to the device that a kind of dry method is extinguished the red heat coke, particularly a kind of dry quenching furnace shell of novel texture.
Background technology
So-called dry coke quenching, relative coke wet quenching is meant and adopts rare gas element with a kind of coke quenching method of red heat coke cooling refrigerative.In the dry coke quenching process, the red heat coke is packed into from the dried furnace roof portion of putting out, the low temperature rare gas element blasts dried putting out in the red burnt layer of stove cooling section by recirculation blower, absorb red burnt sensible heat, cooled coke is discharged from the dried furnace bottom that puts out, and carries out heat exchange from dried high temperature inert gas that ring shape air flue the comes out coke dry quenching boiler of flowing through that puts out, and boiler produces steam, cooled rare gas element blasts the dried stove that puts out again by recirculation blower, and rare gas element recycles in closed system.Because dry coke quenching has obtained using widely in the production of reality at the remarkable advantage of aspects such as energy-saving and environmental protection and raising coke quality.
The dried stove that puts out is a important device in the dry quenching system, is made of metal shell and refractory lining, comprises the charging bole of furnace roof, the chamber that prestores, annular air channel, chute and cooling room.The red heat coke, is discharged from furnace bottom in cooling room and the heat exchange of cold cycle back flow of gas, the cooling that are blasted by furnace bottom from the furnace roof chamber that prestores of packing into again; Recycle gas after the heat exchange becomes red-hot and is carrying the remaining fugitive constituent that coke is separated out secretly, by chute, enter annular air channel, is entering disposable dust remover in the lump in the annular air channel with after mending the air combustion of going into.
Dry quenching furnace shell is the tubular cylindrical steel structure that is welded by steel plate processing, mainly comprises bottom cooling section, middle part annular air channel section and the top section of prestoring three parts.Domestic existing dry quenching furnace shell steel construction mainly relies on the brick plate that is welded on the housing interior annular to bear the weight of the body of heater section of prestoring, cooling section and annular air channel outer wall body.And the dried interior wall that puts out ring shape air flue is built by laying bricks or stones on the chute dividing wall, and the chute dividing wall is a kind of suspended wall brick masonry structure.In the production operation of reality, the dried suspended wall structure of putting out stove chute dividing wall is being born the significant shear power that the annular air channel interior wall produces, also to bear the friction of coke and washing away of high temperature and high speed coke powder simultaneously, these factors are superimposed very big to the destruction of the suspended wall brick structures of chute dividing wall, even cause the fracture of suspended wall brick, cause serious industrial accident.This phenomenon is ubiquity in the dry coke quenching auxiliary at home and abroad, does not have good terms of settlement so far.
Summary of the invention
For solving the problem that prior art exists, it is reliable that the purpose of this utility model provides a kind of intensity, but the dry quenching furnace shell of the novel texture of homodisperse masonry weight, this structure can make the complete homodisperse of weight to the hull outside of walling in the annular air channel strengthen on the steel construction, the suspended wall brick of chute dividing wall can not bear the significant shear power of annular air channel interior wall generation fully and only plays compartmentation, thereby avoided causing the problem of the suspended wall brick structure fracture of chute dividing wall, greatly improved dried work-ing life of putting out stove integral body because of the significant shear power that the annular air channel interior wall produces.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of dry quenching furnace shell of novel texture, comprise the masonry of bottom cooling section, middle part annular air channel section and the top section of prestoring and the housing of masonry outside, the annular air channel section is inside and outside double-layer structure, it is characterized in that, the interior walling of annular air channel section is built by laying bricks or stones on suspension cylinder, suspension cylinder is connected on the upper body, and the section of prestoring masonry hull outside is provided with support steel structure; The hull outside of outer walling of annular air channel section and bottom cooling section masonry is provided with the reinforcement steel construction; Support steel structure is connected with the reinforcement steel construction of annular air channel section outside.
Described suspension cylinder is a tubular construction.
The described section of prestoring masonry is built by laying bricks or stones on the brick plate of top, and the outer walling of annular air channel section is built by laying bricks or stones on the brick plate of middle part, and the cooling section masonry is built by laying bricks or stones on the brick plate of bottom.
Described suspension cylinder is by gas cooling, and suspension cylinder top is provided with some inlet mouths and some air outlets, and the air inlet air flue and the air flue annular space of giving vent to anger are evenly distributed, and lower airways adopts the labyrinth type design.
Described support steel structure annular uniform distribution.
Compared with prior art, the utility model has the advantages that:
The dried annular air channel interior wall that puts out stove is built by laying bricks or stones on suspension cylinder, and does not build by laying bricks or stones on the suspended wall brick of chute dividing wall.The hull outside of outer walling of annular air channel section and bottom cooling section masonry is provided with the reinforcement steel construction.By suspension cylinder, reinforcement steel construction and top braces steel construction, the complete homodisperse of weight that makes walling in the annular air channel is to the reinforcement steel construction of hull outside, thereby the suspended wall brick that can make the chute dividing wall does not bear the significant shear power that walling produces in the annular air channel fully and only plays compartmentation, the problem that the significant shear power that the suspended wall brick structure of effectively having avoided the chute dividing wall produces because of the annular air channel interior wall ruptures has improved dried work-ing life of putting out stove integral body greatly.
