Abstract
The invention discloses a side blown furnace which comprises a water jacket, a furnace body, a hearth and a baking furnace burner, wherein the cross section of the furnace body is rectangular; the hearth is formed by piling a refractory material; a furnace bottom takes the shape of an inverted arch; the furnace body at the upper part of the hearth is formed by the water jacket in a surrounding manner; a heating opening is formed in the water jacket; the baking furnace burner comprises a first air inlet pipeline and a second air pipeline; the second air pipeline is positioned in the first air pipeline; the baking furnace burner penetrates through the heating opening of the water jacket to enter the upper part of the hearth. The side blown furnace provided by the invention has the advantages of being simple in structure, convenient to use, high in utilization ratio of energy sources and good in baking effect.
Description
Technical field
The present invention relates to a kind of non-ferrous metal metallurgy combustion apparatus, belong to chemical industry field of smelting, particularly relate to a kind of side-blown converter.
Background technology
Side-blown converter is with its distinctive version, and burner can only be installed in the jacket sidewall on side-blown converter cupola well top.At present, side-blown converter baker burner all adopts and directly sprays flame-type, and namely flame propagation direction is burner installation direction.Flame is propagated above the cupola well of refractory material laying along burner installation direction, and high-temperature flue gas is directly from top discharge, and only go to heat cupola well by radiant heat transfer, heat up and do not reach even intensification requirement, inefficiency too slowly, energy waste is serious; And the length of flame larger time, be directly injected to opposite jacket sidewall, exist and destroy side-blown converter risk.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, and a kind of effective baker is provided, makes full use of the side-blown converter of the energy.
Technical scheme of the present invention is: a kind of side-blown converter, and it comprises water jacket, body of heater, cupola well and baker burner; Described body of heater cross section is rectangle, and cupola well is that refractory material is piled up, and furnace bottom is invert shape, and cupola well upper furnace body is surrounded by water jacket and be provided with heating gate on water jacket; Described baker burner enters the top of cupola well through the heating gate of water jacket.
The further technical scheme of the present invention is: described baker burner (4) comprises the first admission line and the second admission line, and the second admission line is positioned at the inside of the first admission line.
The further technical scheme of the present invention is: the first described admission line and the second admission line are made up of the oblique section of burner and burner straight section, and the oblique section of burner becomes δ angle with burner straight section.
The further technical scheme of the present invention is: described δ angle is 90o ~ 150o.
The invention has the beneficial effects as follows:
The present invention improves owing to adopting above structure, by regulating burner at the burning capacity of different times, control oven drying temperature, respectively be incubated and the calorific value needs of temperature rise period to meet baker, nozzle flame of the present invention can be directly injected to bottom cupola well, more easily reach the temperature of baker, and can burner be rotated, whole temperature of the furnace hearth is more evenly distributed; The present invention has the advantages such as structure is simple, easy to use, energy utilization rate is high, Baker effect is good.

Detailed description of the invention
Below in conjunction with figure and detailed description of the invention, detailed construction of the present invention is further described.
As shown in Figure 1, Figure 2, Figure 3 shows: a kind of side-blown converter, it comprises water jacket 1, body of heater 2, cupola well 3 and baker burner 4; Described body of heater 2 cross section is rectangle, and cupola well 3 is piled up for refractory material, and furnace bottom is invert shape, and cupola well 3 upper furnace body is surrounded by water jacket 1 and on water jacket, is provided with heating gate 5; The heating gate 5 that described baker burner 4 passes water jacket 1 enters the top of cupola well 3.
Described baker burner 4 comprises the inside that the first admission line 41 and the second admission line 42, second admission line 42 are positioned at the first admission line 41.
The first described admission line 41 and the second admission line 42 are made up of the oblique section 44 of burner and burner straight section 43, the oblique section 44 of burner and burner straight section 43 one-tenth δ angles.
Described δ angle is 90o ~ 150o.
Operation principle of the present invention is: during work, and the first air inlet pipe 41 of side-blown converter is cartridge, thorough fare fuel gas, and the second air inlet pipe 42 of side-blown converter is combustion-supporting gas pipe, thorough fare fuel gas
The useless flue gas of resident family's discharge is outwards discharged by blast pipe 4, useless flue gas promotes valve block 21 and rotates certain angle by valve block hole around valve shaft 22, because valve shaft 22 is arranged on the middle part of blast pipe 4, so whole valve block can all be opened, smooth promotion sealing plate 3 rotates around hinge arrangement, and the flue gas that will give up is all discharged to main air duct.When flue gas is given up in exhaust duct 4 not air draft, sealing plate 3 covers exhaust duct 4 completely, the useless flue gas of other resident family discharge does not enter in the family of resident family by exhaust duct, can only be emitted by main air duct, resident family is played to the effect of good preventing smoke-channeling anti-crossing smell, structure of the present invention is simple simultaneously, convenient for installation and maintenance.
More than show and describe general principle of the present invention and principal character; the technology people of the industry states embodiment and does not limit the present invention in any form; the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, all drops in protection scope of the present invention.
