Abstract
The utility model is related to membrane process oxygen enrichment device for improving the wind temperature of hot blast stove. The device has an air filter, a fan blower connected with the air filter and a membrane process oxygen enrichment generator via a pipe, a vacuum pump connected with the membrane process oxygen enrichment generator via a pipe and a steam separator which is a combustion fan via a pipe. The device can increase the oxygen when hot blast stove is in combustion by changing the ordinary combustion air into the air with oxygen content 21% higher than that of ordinary air, therefore, reducing the factor of combustion excess air with less heat loss due the waste nitrogen, improving the wind temperature of hot blast stove, reducing the cost and saving the energy.
Description
Technical field
The utility model relates to the metallurgy high furnace auxiliary equipment, is a kind of film oxygen enriching device that improves the hot-blast stove wind-warm syndrome.
Background technology
In order to improve the wind-warm syndrome of iron-making heat wind furnace, adopt blast furnace gas to realize with addition of methods such as coke-stove gas or the two preheatings of air gas usually, but the deficiency of these methods is: the cost height, it is big to increase the cost amplitude, wastes a large amount of energy etc.
Summary of the invention
The purpose of this utility model is, a kind of film oxygen enriching device that improves the hot-blast stove wind-warm syndrome is provided, it can increase oxygen when Combustion of Hot Air Furnace, the common combustion air that Combustion of Hot Air Furnace is used is changed into the oxygen-enriched air greater than 21% normal air oxygen content, reduce the combustion air coefficient of excess, the nitrogen exhaust heat is reduced, thereby improve the hot-blast stove wind-warm syndrome, reduce cost, energy savings.
The utility model is in order to finish goal of the invention, following technical scheme is provided: it has air cleaner, air cleaner is connected with air blast, air blast is connected with the film oxygen enriching generator by pipeline, the film oxygen enriching generator is connected with vavuum pump by pipeline, vavuum pump is connected with steam-water separator, and steam-water separator is connected with combustion fan by pipeline.Film oxygen enriching generator one side is isolated oxygen rich gas, and opposite side is isolated nitrogen-rich gas, between nitrogen-rich gas and the air cleaner filtered air air seal separator is set.Can between steam-water separator and hot-blast stove combustion fan, voltage-stablizer be installed.Described vavuum pump is a water ring vacuum pump.
The utility model draws following advantage through on probation repeatedly: increase combustion-supporting oxygen in the time of can making Combustion of Hot Air Furnace, oxygen when making burning in the gas is greater than 21%, nitrogen reduces in a large number, thereby reduced the thermal loss when nitrogen is discharged, reduced the combustion air coefficient of excess, improved the hot-blast stove wind-warm syndrome, reduced cost, energy savings.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
2 is air cleaners among the figure, air cleaner 2 is connected with air blast 3, air blast 3 is connected with film oxygen enriching generator 4 by pipeline, film oxygen enriching generator 4 is connected with water ring vacuum pump 7 by pipeline, water ring vacuum pump 7 is connected with steam-water separator 8, and steam-water separator 8 is connected with combustion fan 10 by pipeline.Voltage-stablizer 9 is installed between steam-water separator 8 and the hot-blast stove combustion fan 10.Film oxygen enriching generator 4 one sides are isolated oxygen rich gas 5, and opposite side is isolated nitrogen-rich gas 6, are provided with the air seal separator between nitrogen-rich gas 6 and air cleaner 2 filtered airs, and nitrogen is fully discharged.During the utility model work, combustion fan 10 is connected with hot-blast stove 11, air 1 enters air cleaner 2, enter film oxygen enriching generator 4 through air blast 3, the isolated oxygen rich gas 5 of film oxygen enriching generator 4 one sides enters hot-blast stove through piping, vavuum pump 7, steam-water separator 8, voltage-stablizer 9, combustion fan 10, the isolated nitrogen-rich gas 6 of the opposite side of film oxygen enriching generator 4 is discharged, the thermal loss when discharging to reduce nitrogen.
