Description
Technical field
The utility model relates to a kind of smoke discharging pipe that is applicable to the recycling of various smelting furnace waste gas, has been specifically related to a kind of insulation smoke discharging pipe that has adopted inside and outside insulation construction.
Background technology
At present, the design of the smoke discharging pipe that uses in the system of some smelting furnace waste gas recyclings, manufacturing mainly contain following two kinds of forms.The one, interior insulation form, namely the high temperature boiler flue gas tube road adopts ordinary carbon steel sheet material to be welded, and the inner refractory brick that adopts is built by laying bricks or stones or inner lining as thermal insulation material and wearing-proof refractory material.In the starting and stopping process of boiler and coal pulverizer, stove cigarette temperature sharply changes between 20-1100 ℃.Because the insulation construction form thermal compensation ability of pipeline itself is relatively poor, refractory brick or insulation material and wearing-proof refractory material will become flexible after operation a period of time, produce obscission, and then the carbon steel steel plate is directly contacted with high-temperature flue gas, cause pipeline owing to hold and can't stand high temperature and burnt out, seriously leak out, cause the dry undertreatment of coal pulverizer, radiation loss to increase, reduce the economy of unit operation.In addition because insulation material and fixedly bitch come off and fall into coal pulverizer, also cause coal pulverizer impeller and beater plate impaired, thereby cause blowing out, shutdown, increased maintenance load, maintenance cost and degree of danger.The 2nd, outer insulation form, namely the smoke pipe road adopts high-temperature alloy steel plate, outsourcing heat-resistant insulation material.In the starting and stopping process of boiler and coal pulverizer, conduit upper mixing chamber position is owing to be subjected to the influence of temperature acute variation, and the tube wall crack performance often appears in the reason of aspect such as processing and manufacturing in addition.In actual moving process, the pipeline that has occurs than long crack, and suspension and support pipe portion snaps, and local fracture appears in pipeline when serious, causes pipeline to sink, and causes blowing out, shutdown.In sum, high temperature boiler flue gas tube road difficult design, investment are greatly at present, service condition is abominable, maintenance workload is big; And the heat-insulating property of pipeline is very poor, can not realize the recycling of high-temperature waste flue gas effectively.Therefore, be badly in need of smoke discharging pipe a kind of new structure, stable performance, high insulating effect on the present production line.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and the insulation smoke discharging pipe of the new structure of a kind of high temperature resistant, corrosion-resistant, not fragile, long service life, high insulating effect is provided.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of insulation smoke discharging pipe, wherein, this smoke discharging pipe adopts inside and outside insulation construction, is provided with the high-temperature wearable ramming bed of material, grid tempering net, ceramic silicate aluminum board, alkali resistance clay layer, smoke pipe, rock wool heat-preservation plate and aluminium sheet from the inside to the outside successively; Described alkali resistance clay layer spreads upon on the inwall of smoke pipe, and is provided with fixedly hook nail between alkali resistance clay layer and the grid tempering net.
Adopt inside and outside insulation construction, not only play good heat insulation effect, be convenient to improve the recycling rate of useless flue gas, and can the better protection smoke discharging pipe, prolong smoke discharging pipe service life, reduce the generation of production fault.And the fixedly hook nail that arranges can with the high-temperature wearable ramming bed of material, grid tempering net, ceramic silicate aluminum board, alkali resistance clay layer as a firm overall fixed on the inwall of smoke pipe.
As further specifying, the spacing that arranges of above-described fixedly hook nail is 15～25cm, preferred 20cm.Such spacing setting can be reinforced the integral body that the high-temperature wearable ramming bed of material, grid tempering net, ceramic silicate aluminum board, alkali resistance clay layer are formed, be difficult for causing each pull-up from.Above-mentioned spacing is the spacing coordinate in the plane coordinate system.
As further specifying, the thickness of above-described alkali resistance clay layer is 3～5mm.
As further specifying, above-described grid tempering net is Ф 2.5mm～Ф 4mm grid tempering net, preferred Ф 3.2mm grid tempering net.The use that combines with fixing hook nail of grid tempering net makes the high-temperature wearable ramming bed of material, grid tempering net, ceramic silicate aluminum board, alkali resistance clay layer become a firm integral body.
As further specifying, the thickness of the above-described high-temperature wearable ramming bed of material is 30～50mm, preferred 40mm; The thickness of described ceramic silicate aluminum board is 50～70mm, preferred 60mm; The thickness of described rock wool heat-preservation plate is 70～90mm, preferred 80mm; The thickness of described aluminium sheet is 0.5～0.8mm, preferred 0.7mm.
Layers of material in the utility model structure is bought on all can market and is obtained.
Compared with prior art, the beneficial effect that possesses of the utility model:
1. the fine and environmental protection and energy saving of heat insulation effect.Adopt inside and outside insulation construction, farthest reduced the heat dissipation capacity of useless flue gas, made us effectively to carry out recycling to high-temperature waste flue gas fully, realized energy-conserving and environment-protective.
2. high temperature resistant, corrosion-resistant, not fragile, long service life.By the material selection of each level and the structural configuration of each level, greatly reduce the incidence of production fault, reduced maintenance load, also just reduced production cost, efficiently solved present high temperature boiler flue gas tube road difficult design, invest the problem big, that maintenance workload is big.
