Abstract
The invention relates to a movable gas burner for blow-in heating of a smelting furnace for use in KIVCET lead and zinc smelting process. The movable gas burner comprises a burner body and a burning control system. A lifting mechanism is connected to the burner body and comprises a frame, a motor, a drive chain, a slide rail and a limit mechanism. The burning control system controls the burner body to move through the lifting mechanism, the traditional burner fixed installation way is broken, long-term exposure to high-temperature radiation in a hearth during idling is avoided, and the service life of the burner is prolonged. The movable gas burner is high in burning efficiency, allows for high-integrated automatic control, allows for remote ignition and control and is high in safety.
Description
Technical field
The present invention relates to the removable gas combustion apparatus of KIVCET smelting furnace blow-on intensification use in a kind of KIVCET lead-zinc smelting technique.
Background technology
Existing gas burner is mainly fixed, and separate unit combustion power is below 15MW, and combustion gas mixes inhomogeneous with combustion air.The problem that traditional burner exists has: (1) burner is fixed on the burner installing port of body of heater, while not using, easily occurs due to the hyperthermia radiation of accepting for a long time in burner hearth fragile burner; (2) combustion power is little, and large-scale industrial furnace needs a plurality of burners conventionally, and several burners use simultaneously, easily form and interfere with each other; (3) the burn-off rate of combustion gas is low, and incomplete combustion produces a large amount of pollution, and energy consumption is higher; (4) control system is complicated, easily occurs control system fault.
Summary of the invention
For defect and the deficiency of existing gas burner, the object of the present invention is to provide that a kind of efficiency of combustion is high, long service life and gas burner movably.
The object of the present invention is achieved like this:
A removable gas combustion apparatus, comprises gas burner and combustion control system, and gas burner is connected with elevating mechanism, and elevating mechanism comprises frame, and frame is provided with motor, driving chain, sliding rail and position-limit mechanism; Gas burner is connected with rotatable combustion air air channel;
Described gas burner is comprised of igniter burner, central burner nozzle, annular auxiliary burning nozzle, air duct, and igniter burner is for adopting the sleeve of windproof structure;
Described combustion control system is by PLC, control valve group, chain and ignition controller, flame detector, temperature control and chain composition;
Described motor is the motor with electromagnetic brake.
The present invention compared to existing technology tool has the following advantages:
The present invention controls by PLC gas burner mobile by elevating mechanism, the burner that breaks traditions is fixed on the mounting means of body of heater, avoids when not using, accepting for a long time the hyperthermia radiation in burner hearth, has extended service life; Gas burner adopts the multiinjector combining structure of annular auxiliary burning nozzle and central burner nozzle, in limited space, strengthened mixing of combustion gas and air, improve the volume calorific intensity of burning, strengthened the rigidity of flame, improve efficiency of combustion, improved the burn-off rate of combustion gas, reduced the pollution producing because of incomplete combustion, in protection of the environment, reduce energy consumption, improved economic benefit; The design of multiinjector combining structure, has improved efficiency of combustion, and separate unit burner combustion power reaches 25MW, can reduce the usage quantity of burner, reduces furnace volume, has avoided the interference between a plurality of burners, reduces and controls fault; Igniter burner adopts the sleeve of windproof structure, can realize the igniting under high wind speed, and keeps the rigidity of the stable and flame of flame, has improved igniting security; Rotating combustion air air channel can move up and down with burner; Realize highly integrated automation and control, can realize long-range igniting and control, high safety.

The specific embodiment:
The present invention also in connection with accompanying drawing to being described in further detail:
1, a kind of removable gas combustion apparatus, comprise gas burner 1 and combustion control system, gas burner 1 is connected with elevating mechanism 2, and elevating mechanism comprises frame 9, and frame 9 is provided with as the motor with electromagnetic brake, driving chain 10, sliding rail 11 and position-limit mechanism 12; Gas burner 1 is connected with rotatable combustion air air channel 3; Gas burner 1 is comprised of igniter burner 4, central burner nozzle 5, annular auxiliary burning nozzle 6, air duct 7, and igniter burner 4 is for adopting the sleeve of windproof structure; Combustion control system is by PLC, control valve group, chain and ignition controller, flame detector, temperature control and chain composition;
When smelting furnace blow-on heats up, the natural gas coming from pipe network enters igniter burner 4, by electronic lighter, is lighted, after its flameholding, to central burner nozzle 5, annular auxiliary burning nozzle 6, for natural gas, when gas spraying injects burner hearth, by igniter burner 4, lighted; Annular air duct 7, diameter is less, can be so that the wind speed of burner 1 outlet surpass 50m/s at full capacity time, can effectively to burner nozzle, carry out coolingly, reduced the erosion of hyperthermia radiation to burner 1.
After burner 1 is used to complete and stops working, burner 1 need be extracted out from body of heater installation site, is arranged on the transmission system 8 in frame 9, drives driving chain 10 to drag burner 1 and moves up along sliding rail 11, when moving to precalculated position, by position-limit mechanism 12, be fixed.Rotatable combustion air air channel 3 is mainly comprised of slip-knot 13 and airduct 14, and under the drive of elevating mechanism 2, the slip-knot 13 on air channel rotates, thereby makes airduct 14 at one end in fixing situation, and the other end moves together with burner 1.Combustion control system is controlled by PLC, and according to instruction, control transmission system 8 drives driving chains 10 to drag burner 1 and slides on sliding rail 11, is provided with position-limit mechanism 12, can realize accurate control.Flame detects chain control transmission system 8, and burner 1 can not extracted out because of maloperation in use; The chain ignition controller of position-limit mechanism 12, makes the burner 1 can air feed and igniting when extracting out.PLC controls the flow of combustion air according to gas discharge, realize the proportion control of natural gas and combustion air.
