Description
Technical field
The utility model is related to a kind of clean type heat reclamation coke furnace more particularly to the connection burnings of lower-discharging type heat recovery coke oven
The arch crown structure of high temperature channel between room and gas collecting tube.
Background technology
Clean type heat recovery coke oven using negative pressure due to being run, the not outer smoke evacuation dirt in process of coking, to air and water ring
Border is pollution-free, and can be by the coke oven flue-gas generated in process of coking, chemical products and some harmful substances inside coke oven
Rationally fully burning, the heat for recycling high-temp waste gas are used for generating electricity or other purposes, realize the comprehensive utilization of thermal energy, and obtain
More and more extensive concern and application.
Clean type heat recovery coke oven mainly includes key components, the combustion chambers such as carbonization chamber, combustion chamber and gas collecting tube and is located at charcoal
Change the bottom of room, gas collecting tube is then located at the top of entire coke oven；In current structure, the indoor high-temp waste gas that burns need through
The rising quirk crossed on coking furnace shaft send gas collecting tube and gas gathering manifold to coke oven, and most high-temp waste gas is sent to waste heat pot at last
Stove generates steam-electric power.Present this coke oven construction, builds and is required to carry out construction operation at the top of coke oven when safeguarding, not only
Construction maintenance difficulty and project cost are increased, and so that the space layout of the high-temp waste gas conveyance conduit of coke oven is complicated, is accounted for
It is big according to space.Therefore industry gradually designs a kind of heat recovery coke oven with lower-discharging type structure, in this heat recovery coke oven,
Gas collecting tube and gas gathering manifold arrangement below ground, the high-temp waste gas of combustion chamber are transported to gas collecting tube or gas collection by high temperature road cigarette
In manifold.
It is that entire heat recovery coke oven temperature is highest since the exhaust gas temperature in high-temperature flue is up to 1300 DEG C -1350 DEG C
Position, and contain water vapour, SO in exhaust gas2, the unwanted corrosions gas such as CO, flue high temperature heat wave air-flow is rapid, rapidly
High temperature gas flow can generate strong impact and Eroded to flue wall surface.The vault construction of high-temperature flue should undertake itself and
The weight on flue top is washed away erosion by high temperature gas flow again, is part the weakest in entire high temperature road cigarette, forms
The refractory brick on kiln top or building block are easy to generate cracking and come off, and then lead to subsideing or even collapsing, serious shadow for kiln vault
Ring the service life of kiln and being normally carried out for production.

In said structure, since flue vault is formed by brick, vault side brick and vault foot brick masonry among vault
Arc arch-type structure, and brick both sides have built vault side brick by laying bricks or stones respectively among vault, and vault side brick is supported on corresponding arch
It pushing up on foot brick, brick is in itself and flue gravity makes the more to paste the more close between brick, vault side brick and vault foot brick among vault,
It is not only unlikely to deform and cracks, but also form stable and firm vault construction, be more tolerant of the impact and erosion of high temperature gas flow, together
This spline structure of sample is also convenient for building construction and repair is replaced；It is long with service life, the characteristics of heat shock resistance and high mechanical strength.
Again since the vault construction in the utility model is assembled by building block, build by laying bricks or stones and repair convenient for scene, advantageously reduce
Use cost improves the safety used and service life, has the characteristics that build and easy to maintenance convenient,
The preferred embodiment of the utility model, brick includes intermediate brick top surface, intermediate brick bottom surface and right among the vault
Claim the intermediate brick folding face in both sides, which is made of intersecting vertical side and skew back face.The vault side Zhuan Bao
Side brick top surface, side brick bottom surface and the side brick folding face positioned at both sides are included, side brick bottom surface is mutually inclined setting with side brick top surface, is located at
The side brick folding face in outside is made of intersecting outer vertical plane and outer slope, and the side brick folding face positioned inside is by intersecting interior vertical plane
It is formed with interior slope surface.The vault foot brick include top surface, side plane, bottom surface and side folding face, the side plane respectively with top surface and
Plane perpendicular intersects, and plug tenon is equipped on bottom surface, the side folding face is by the short sides slope intersected successively and containing slope surface structure
Into.Vault side brick is interlocked with its interior vertical plane and interior slope surface with the vertical side of intermediate brick respective side and skew back face, should
Vault side brick is interlocked with its outer vertical plane and outer slope and the short sides and slope of vault foot brick.This structure forms vault
Inclined-plane between intermediate brick, side brick and skew block is mutually matched fitting, and not only good airproof performance, but also stability of strutting system is strong improves
The stability of vault construction and anti-ability of caving in.
The further embodiment of the utility model, the vault brick cup, the top surface of the vault brick cup are equipped with slot, institute
The plug tenon for stating vault foot brick is plugged in the slot of vault brick cup, and tenon is provided on the bottom surface of vault brick cup.The branch of the structure
Good connecting effect, structure more firm stable are supportted, and the infiltration of high-temperature gas can be blocked again and ganged up, improves thermal insulation separation thermal effect
Fruit.
