Abstract

The utility model provides an oxygen oil lance and relates to an oxygen oil lance of reverberator for smelting of material containing nickel, such as nickel concentrate and high nickel matte. The utility model is characterized in that the oxygen oil lance is multiple-layer casing-typed and the casing sequentially comprises a heavy oil tube, a compression air inlet tube, an oxygen tube and a cooling water casing from the center to outside. An oxygen burner of the utility model adopts pure oxygen combustion-supporting heavy oil, flame temperature of the oxygen oil burner is about 1600 celsius degrees, flame length is less than 1500mm, a jet angle is less than 90 degrees, flame sprays onto material slope directly, material smelting capacity of the middle and back part of a smelting area is improved, and meanwhile, temperature of the back part of a hearth is stabilized beyond 1400 celsius degrees.

Description

A kind of oxygen rusting rifle

Technical field

A kind of oxygen rusting rifle relates to the oxygen rusting rifle that a kind of reverberatory furnace that is used for nickel-containing material meltings such as nickel ore concentrate and high ice nickel uses.

Background technology

In nickel-containing material fusion process such as nickel ore concentrate and high ice nickel, the oxygen rifle fuel of traditional reverberatory furnace is diesel oil, and oxygen-enriched air is made combustion adjuvant, does not have Alevaire.And the new type reflection stove adopts fine coal to make main fuel, uses oxygen-enriched air to make combustion adjuvant, the flame temperature when having improved pulverized coal friring, but the length of flame has shortened, because new type reflection furnace body longer dimension is unfavorable for stove rear portion material melting like this, it is constant also can't to keep the burner hearth rear part temperature.At the furnace roof of fusion zone postmedian new fuel burning rifle being installed is the effective ways of dealing with problems.For this reason, need a kind of novel fuel to burn rifle.

Summary of the invention

The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, the novel oxygen rusting rifle that provides a kind of furnace roof that is adapted at reverberatory furnace fusion zone postmedian to install.

The purpose of this utility model is achieved through the following technical solutions.

A kind of oxygen rusting rifle is characterized in that this oxygen rusting rifle is a multilayer sleeve formula form, and this sleeve pipe outwards is followed successively by by the center:

Oil pipe-this pipe is positioned at the pipe box center, is the heavy oil access tube, and an end is for connecing heavy oil oil-feed ozzle, in the other end retraction sleeve pipe;

Outside compressed air inlet pipe-this pipe box dress oil pipe, end sealing is fixed on the oil pipe oil inlet end outer wall, and is provided with compressed air inlet pipe on the side pipe wall of this end, the uncovered oil pipe exit that is positioned at of the other end;

Oxygen hose-this pipe box is contained in outside the compressed air inlet pipe, and end sealing is fixed on the compressed air inlet pipe inlet end outer wall, and is provided with oxygen intake pipe on this distolateral tube wall, and uncovered the growing of the other end is positioned at the compressed air inlet pipe exit;

Cooling water pipe-this cooling water pipe is placed in outside the oxygen intake pipe, and end sealing is fixed on the outer wall of oxygen intake pipe outlet side; Other end sealing is fixed in the oxygen intake pipe end, and is provided with cooling water inlet pipe and outlet pipe on the sidewall of this end; Be fixed with connecting flange near on the tube wall of water inlet pipe;

Mounting sleeve-this casing pipe sleeve is loaded on outside the cooling water pipe, and an end connects with cooling water pipe flange outward.

Oxygen rusting rifle of the present utility model is to adopt the combustion-supporting RF oxygen rusting rifle of pure oxygen, and the heavy oil atomizing adopts compressed air to finish, and new oxygen rusting rifle flame combustion cross section is a plate-like, and coverage rate is bigger; For anti-block rusting rifle is burnt out by flame, oxygen rusting rifle outer tube is designed to the water jacket cooling structure, and cooling water is supplied with by the body of heater circulation.Oxygen oil burner of the present utility model adopts the combustion-supporting heavy oil of pure oxygen, and oxygen oil burner flame temperature is about 1600 ℃, flame length control is at～1500mm, jet angle～90 °, the straight material spray of flame slope, improve the change material ability of fusion zone postmedian, stablize the burner hearth rear part temperature simultaneously more than 1400 ℃.

The specific embodiment

A kind of oxygen rusting rifle is characterized in that this oxygen rusting rifle is a multilayer sleeve formula form, and this sleeve pipe outwards is followed successively by by the center: this pipe of oil pipe 4-is positioned at the pipe box center, is the heavy oil access tube, and an end is for connecing heavy oil oil-feed ozzle, in the other end retraction sleeve pipe; Outside this pipe box dress oil pipe of compressed air inlet pipe 3-, end sealing is fixed on the oil pipe oil inlet end outer wall, and is provided with compressed air inlet pipe on the side pipe wall of this end, the uncovered oil pipe exit that is positioned at of the other end; This pipe box of oxygen hose 2-is contained in outside the compressed air inlet pipe, and end sealing is fixed on the compressed air inlet pipe inlet end outer wall, and is provided with oxygen intake pipe on this distolateral tube wall, and uncovered the growing of the other end is positioned at the compressed air inlet pipe exit; This cooling water pipe of cooling water pipe 7-is placed in outside the oxygen intake pipe, and end sealing is fixed on the outer wall of oxygen intake pipe outlet side; Other end sealing is fixed in the oxygen intake pipe end, and is provided with cooling water inlet pipe 1 and outlet pipe 5 on the sidewall of this end; Be fixed with connecting flange near on the tube wall of water inlet pipe; This casing pipe sleeve of mounting sleeve 6-is loaded on outside the cooling water pipe, and an end connects with cooling water pipe flange outward.

During use, oxygen rusting rifle is contained in the furnace roof top of reverberatory furnace fusion zone postmedian, sprays into oil and mixes with compressed air, combustion-supporting with pure oxygen, cooling water prevents that by body of heater circulation supply cooling jacket block rusting rifle is burnt out by flame.
