Description
Technical field
The utility model relates to gas furnace and adds burnt equipment, refers in particular to the coal rod drying of intermittent type fixed level gas cooker and adds burnt coal rod automatic drying coke charger equipment automatically.
Background technology
At present, nitrogenous fertilizer enterprises mostly still is that raw material adopts the intermittent type fixed level gas cooker to produce syngas for synthetic ammonia with the coal, because the high goods of lump coal valency is tight, minority producer is not for reducing raw materials cost, progressively abandon using lump coal to use coal rod system gas instead, but the moisture content height of coal rod, wet coal rod is moist not only cannot realize adding automatically Jiao, and wet coal rod is gone into stove and also can be increased the stove calorific loss, influence furnace temperature, reduce gasification efficiency, reduce gas forming amount, cause production energy consumption to increase, restricted applying of coal rod gasification technology.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, provide a kind of gas furnace low grade residual heat that utilizes that wet coal rod is carried out vacuum-drying, realize adding Jiao automatically in the coal rod gas-making process, improve the gasification efficiency of gas furnace, reach energy-saving and cost-reducing coal rod automatic drying coke charger.
The technical solution of the utility model is a kind of comprising of structure:
At the top of gas furnace burnt bucket and coke containing barrel are set, in the burner hearth of fire door lower end distributor are set, the fire door outside is passed the furnace roof thermofin hydraulic gear is set.
Wherein: the interface between burnt bucket and the coke containing barrel is provided with push-pull valve and slide valve.
Interface between coke containing barrel and the fire door is provided with push-pull valve and slide valve.
The sparger that the outlet setting of distributor is driven by hydraulic gear.
Wherein: coke containing barrel is provided for drying the vacuum-drying facility of coal rod; Be provided for adding the vacuum-drying mechanism of hot coal rod in the coke containing barrel; Distributor is set to and up coal gas of burner hearth and the Open architecture that communicates of blowing hot gas.
Advantage of the present utility model and beneficial effect:
The utility model integrates coal rod drying and adds burnt automatically, be applied on the intermittent type fixed level gas cooker, the coal rod that wets can be carried out drying on the one hand, reduce significantly and go into the stove moisture content of coal, improve the thermostability and the hot strength of coal rod, reduce explosion, the change powder phenomenon of coal rod in stove, reduce the furnace heat loss, stablize furnace temperature, accelerate gasification reaction, improve steam decomposition rate; Can realize on the other hand adding Jiao automatically in the coal rod gasification, the Stable Carbon layer height, increase system gas time and gas forming amount, improve gasification efficiency and efficiency of energy utilization, the technical progress that promotes coal rod gasifying process is fit to medium and small nitrogen fertilizer plant intermittent type fixed level gas cooker and uses with energy-saving and cost-reducing very much.

Embodiment
By accompanying drawing as can be known, the utility model comprises:
At the top of gas furnace burnt bucket 1 and coke containing barrel 4 are set, in the burner hearth of fire door lower end distributor 7 are set, the fire door outside is passed the furnace roof thermofin hydraulic gear 9 is set.
Wherein: the interface between burnt bucket 1 and the coke containing barrel 4 is provided with push-pull valve 2 and slide valve 3.
Interface between coke containing barrel 4 and the fire door is provided with push-pull valve 5 and slide valve 6.
The sparger 8 that the outlet setting of distributor 7 is driven by hydraulic gear 9.
Wherein: coke containing barrel 4 is provided for drying the vacuum-drying facility of coal rod; Be provided for adding the vacuum-drying mechanism of hot coal rod in the coke containing barrel 4; Distributor 7 is set to and up coal gas of burner hearth and the Open architecture that communicates of blowing hot gas.
Vacuum-drying described in the utility model mechanism is included in heating coil 10 and the hot water import and export thereof that coke containing barrel 4 inwalls are provided with and takes over.Described vacuum-drying mechanism also is included in coke containing barrel 4 tops one side induced draft fan venting port 11 is set.Described distributor 7 shells are mesh plate multi-clove type unitized construction.
The utility model comprises that the coal rod is dry and adds burnt technology two portions.
The coal rod is dry, is wet coal rod to be placed carry out vacuum-drying under the condition of negative pressure.With pipeline the hot water in the gas furnace drum is introduced heating coil in the coke containing barrel, improve the temperature in the coke containing barrel, the water vapor that the coal rod is evaporated is taken out negative excluding from the venting port of coke containing barrel top one side by induced draft fan, and make and form negative pressure state in the coke containing barrel, accelerate the vaporator rate of coal rod surface-moisture, coal rod surface and inner moisture gradient increase, and promote the vaporization of coal rod internal moisture, make the rapid drying of coal rod; After coal rod in the coke containing barrel drops to distributor, by the waste heat baking of up coal gas and blowing air, make the coal rod obtain further drying again.
The coal rod adds Jiao, be stored in the wet coal rod in the burnt bucket, regularly join and carry out vacuum-drying in the coke containing barrel through push-pull valve 2, slide valve 3 controls, dried coal rod regularly drops in the distributor by push-pull valve 5, slide valve 6 controls again, drives conical distributor by hydraulic gear then and adds Jiao automatically by processing requirement.
