Abstract
The invention discloses a clean thermal recycling coke oven gas collecting pipe which belongs to the industrial kiln accessory field and comprises an outer casing and a liner. The gas collecting pipe is characterized in that the liner is composed of a primary adiabatic layer and a secondary adiabatic layer which is arranged between the primary adiabatic layer and the outer casing. The primary adiabatic layer is made of carburizing resistance mullite bricks which are packed through high temperature binders. The secondary adiabatic layer is made of insulation silicate material solidified through high aluminum binders. Compared with the prior art, the clean thermal recycling coke oven gas collecting pipe has the characteristics of light weight, high temperature resistance, low heat conduction, etc.
Description
Technical field
The present invention relates to a kind of annex of Industrial Stoves, especially a kind of cleaning type gas collecting pipe for thermal recovery coke oven.
Background technology
Effuser is to be used to collect coke oven exhaust gas, a kind of air transporting arrangement that utilizes waste gas residual heat to generate electricity then, use of the inner lining material of effuser contains zircon ceramic fiber folded piece more at present, use the high temperature resistant stainless steel anchoring piece to be fixed on the carbon steel shell, the design heat resisting temperature is 1250 ℃, but because not fully burning of part raw gas, through the rising quirk, bridge tube, enter the effuser arm, produce secondary combustion, cause the temperature of gas collection arm to surpass design temperature, reach 1300 ℃, cause containing zircon ceramic fiber folded piece generation volumetric shrinkage, produce the slit, high-temperature flue gas then burns out the stainless steel anchoring piece by the slit, make that containing the zircon ceramic folded piece comes off, cause the carbon steel shell to burn, cause Cryogenic air to be scurried in the effuser, thereby reduced the flue-gas temperature that enters boiler, reduced capacity of boiler, and because the leakage of effuser causes the suction of coke oven to reduce, thereby the coking time of coke prolongs, and influenced the output of coke.
Summary of the invention
Technical assignment of the present invention is to provide a kind of a kind of cleaning type gas collecting pipe for thermal recovery coke oven that mainly provides at above the deficiencies in the prior art, and this effuser liner has characteristics such as in light weight, high temperature resistant, that heat conduction is low.
The technical solution adopted for the present invention to solve the technical problems is a cleaning type gas collecting pipe for thermal recovery coke oven, constitute by shell and liner, it is characterized in that described liner is made of one-level thermal insulation layer and the secondary thermal insulation layer between described one-level thermal insulation layer and shell, described one-level thermal insulation layer is piled up by high-temperature agglomerant by impervious carbon mullite brick and is formed, and described secondary thermal insulation layer is formed by the high aluminium binder adhesive solidification by the insulation silicate material.
Described insulation silicate material is an aluminosilicate fiber cotton.
Described insulation silicate material is an asbestos-free calcium silicate.
Upper part of described secondary thermal insulation layer is an aluminosilicate fiber cotton, and lower part is an asbestos-free calcium silicate.
The present invention compared with prior art has following useful effect:
1, thermotolerance height, percent thermal shrinkage is low, and therefore the phenomenon in slit can not take place to produce because of the liner volumetric shrinkage up to more than 1300 ℃ in heat resisting temperature.
2, thermal conductivity is lower, and thermosteresis is few, has guaranteed to enter the flue-gas temperature in the boiler, has improved capacity of boiler.
3, the suction that has kept flue gas in the coke oven makes the coking time of coke shorten, and has improved the output of coke.
4, inner lining material is selected the light-weight lagging material for use, thereby greatly reduces the overall weight of effuser, has reduced the load-carrying load of furnace stay.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Below in conjunction with Figure of description the present invention is done following detailed explanation.
As shown in the figure, this effuser is made of shell 1 and liner, wherein liner is made of one-level thermal insulation layer 2 and the secondary thermal insulation layer 3 between one-level thermal insulation layer 2 and shell 1, one-level thermal insulation layer 2 is piled up by high-temperature agglomerant by impervious carbon mullite brick and is formed, the consumption of above-mentioned high-temperature agglomerant is that every block of impervious carbon mullite brick is with 0.44 kilogram, secondary thermal insulation layer 3 is that the asbestos-free calcium silicate 5 by its upper part aluminosilicate fiber cotton 4 and its lower part forms by the high aluminium binder adhesive solidification, and the consumption of above-mentioned high aluminium binder is that every square metre of insulation silicate material is with 1 kilogram.Above-mentioned secondary thermal insulation layer also can directly be selected aluminosilicate fiber cotton or asbestos-free calcium silicate for use.
Claims (4)
