Abstract
The utility model provides an inhalator, which is provided with a casing. An airflow injecting nozzle is installed in the casing, and the airflow injecting nozzle is connected with and communicated with a water flow distributing tube; a water feeding port is formed on the casing, and the other end of the water flow distributing tube is a steam fog ejecting port. The utility model can enable water and high voltage inert gases to generate steam fog after the water and the gases are passed through the inhalator, and the steam fog can be led to a cooling wall to cool the cooling wall, which can lengthen the service life of the cooling wall.
Description
Technical field
The utility model relates to steelmaking furnace cooling technology field, is a kind of blast furnace cooling stave to be kept the refrigerative Inhalator.
Background technology
The polylith cooling stave is installed around the iron-smelting blast furnace furnace wall, is fed cycle of higher pressure water in the cooling stave and cool off, thereby realize the cooling of body of heater and furnace lining, reach and keep the regular and furnace shell steel construction of blast furnace lines to be unlikely to the purpose of being out of shape, damaging.The method of this employing cycle of higher pressure water cooling blast furnace, there is some deficiency: when cooling wall breakage leaks, when the method that adopt to reduce pressure of supply water and flow is kept cooling and can't be carried out, adopt Inhalator in blast furnace cooling stave, to spray into steam fog, make blast furnace cooling stave continue to keep cooling.
Summary of the invention
The purpose of this utility model provides a kind of Inhalator, makes water and high-pressure inert gas by behind the Inhalator, produces steam fog, this steam fog is imported cooling stave make cooling stave obtain cooling, can prolong the life-span of cooling stave.
The utility model is achieved through the following technical solutions for achieving the above object: Inhalator, and it has housing, airflow nozzle is installed in the housing, airflow nozzle is connected with current distribution tube and communicates, and offers the feed water inlet on the housing, and a current distribution tube the other end is the steam fog ejiction opening.Offer several apertures on the circumference of current distribution tube.Offer several grooves on the circumference of current distribution tube.Current distribution tube and airflow nozzle joint preset clearance can replace aperture and groove and realize that Inhalator supplies water.
The utlity model has following advantage: can prolong the life-span of cooling stave significantly, and then prolong blast furnace campaign, be that the cooling stave that leaked is kept the refrigerative ideal device.
Description of drawings
Accompanying drawing 1 is the utility model structural representation; Accompanying drawing 2 is one of the utility model embodiment structural representations.
Embodiment
5 is housings among the figure, and airflow nozzle 1 is installed in the housing 5, and airflow nozzle 1 is connected with current distribution tube 2 and communicates, and offers feed water inlet 3 on the housing 5, and current distribution tube 2 the other ends are steam fog ejiction opening 4.The utility model current distribution tube 2 can have multiple structure, as shown in Figure 1, offer several apertures 6 on current distribution tube 2 circumference, current are entered by feed water inlet 3, by the aperture 6 ejection water columns on current distribution tube 2 circumference, the high speed steam flow is through airflow nozzle 1 ejection, impinge upon with the vertical water column of current on, crash water column after, form steam fog, steam fog enters blast furnace cooling stave from 4 ejections of steam fog ejiction opening, reaches the purpose of cooling body of heater and furnace lining.Also can offer several grooves 7 on the circumference of the utility model current distribution tube 2, as shown in Figure 2, make the water of ejection form water column, current distribution tube 2 of the present utility model and airflow nozzle 1 joint also can be reserved the circular clearance, make the current ejection form water curtain.
