Description
Technical field
The utility model belongs to the coke production field, relates to a kind of dried stove that puts out that is used for dry coke quenching technology, especially a kind of coke dry quenching furnace body of heater.
Background technology
Dry coke quenching technology is changed the technology that water in the past cools down scorching hot coke, be by with scorching hot coke by dried put out in the stove to extinguish with cold rare gas element make coke product, efficient, the environmental protection of this technology and superiority such as energy-conservation are by the approval of a lot of coking producers.Coke dry quenching furnace is a major equipment in dry coke quenching technology.Scorching hot coke is put into dried putting out in the stove, carries out the adverse current cooling with cold rare gas element within it, again by the dried coke discharging device that puts out furnace bottom will be cold the coke discharge, and make the coke finished product, be transported to the user.
Traditional dried furnace body that puts out adopts heat-stable material to build by laying bricks or stones to form more, build it and generally need the long duration, in addition, because coke dry quenching furnace is variation of temperature in use, contained burnt dirt washes away in the corrosion of gas and coke and the recycle gas, the body of building by laying bricks or stones of body of heater very easily weares and teares, come off, have again, the cooling gas of existing body of heater none in the wall of body of heater distributes more uniformly, often cause the body of heater local superheating, therefore, existing dried work-ing life of putting out stove is shorter, seriously influences production efficiency thus, moreover the existing dried stove that puts out keeps in repair also cumbersome.
Summary of the invention
The purpose of this utility model is to improve the defective of prior art, and the short dried furnace body that puts out of a kind of completion time of project is provided, and the further purpose of the utility model is to provide a kind of dried furnace body that puts out of long service life.
For achieving the above object, the utility model is taked following design:
Trunk put out furnace body comprise driedly put out furnace shell, the chamber that prestores, circulation air path and coke quencher, constitute burner hearth in the furnace shell described dried putting out, coke quencher is the position of seriously corroded.Be provided with heat-resistant material layer on the inwall of this coke quencher's furnace shell, described heat-resistant material layer is on the make made by methods such as casting for the section bar material that looses.Because the dried furnace body that puts out that the utility model provides is to establish described heat-resistant material layer in a metal furnace shell, so it is easy to make.
In described heat-resistant material layer, can also set firmly water-cooled tube.
Set firmly water-cooled tube in heat-resistant material layer, logical therein in process of production water coolant both can protect body of heater not damaged by the coke pyritous effectively, improved the life-span of body of heater, and simultaneously, water coolant can also further be utilized by the heat of taking away in the coke.
For fear of the different thermal stresses that cause of expanded by heating rate of furnace shell of making because of unlike material and heat-resistant material layer, preferably between described furnace shell and heat-resistant material layer, establish one deck elasticity heat-resistant material layer, as asbestos plate etc.
For the heat interchanging area that improves water-cooled tube and water pipe the firmness that combines, can be provided with the dowel plate being located on the water coolant tube wall of heat-resistant material layer inside with heat-resistant material layer.
In the furnace binding of reality, can in heat-resistant material layer, establish some short water coolant pipeline sections, its two ends are established elbow and are established the hole by corresponding position on the furnace shell, stretch out outside furnace shell, connect U type pipe connecting hermetically and constitute water-cooled tube thus between the elbow of described short water coolant pipeline section in twos.
In making, concrete body of heater above-mentioned some short water-cooled tube can be welded on the inwall of described furnace shell.
Described heat-resistant material layer can be made up of one one heat-stable material module, also can be provided with described short water coolant pipeline section in described heat-stable material module.
The dried circulation air path that puts out stove is corroded the most serious place, can not establish water-cooled tube in the heat-stable material with it with prefabricated outside in aggregates the lifting then in the stove of heat-stable material.Described independently circulation air path is fixing in body of heater, the expansible problem is arranged when temperature raises,, between described circulation air path and described body of heater, be provided with the slit for fear of the thermal expansion and the damage of body of heater because of circulation air path, in this slit, be provided with resistant to elevated temperatures cushion, as graphite pads.
In addition, can on the furnace wall of the chamber that prestores of this body of heater, establish several flues around its periphery, described flue is preferably twin flue, promptly in flue passage from bottom to top, be provided with a necking down, the upper end of some of them flue communicates with atmosphere, port is provided with valve thereon, if the amount of oxygen in the stove manually or is automatically opened this valve eliminating oxygen and burnt when big.This structure can make cooling gas uniform distribution in body of heater from bottom to top, does not make the body of heater local superheating, and the twin flue structure that has necking down simultaneously can reduce the discharging of environment towards periphery of coke dust, helps environmental protection.
The dried furnace body that puts out that the utility model provides is by establishing the heat-resistant material layer of the type that looses in coke quencher's furnace shell, it is made than being built into much easier one by one with brick, and establish water-cooled tube therein, improved the work-ing life of body of heater, and heat-stable material and water-cooled tube are formed module or integrated poured being integral, the easiest circulation air path that is corroded is prefabricated into one in addition and is located in the stove with the isolating integral body of body of heater, therefore, make the manufacturing of body of heater and maintenance become convenient.
