Abstract
The utility model discloses a burner nozzle of a suspension roaster, which relates to the improvement on the burner nozzle structure of the suspension roaster during the roasting process of alumina. The burner nozzle of the suspension roaster comprises a tubular burner nozzle base body which is provided with a jet hole at the end part, and a connecting flange arranged at the tail end of the burner nozzle base body. The burner nozzle of the suspension roaster is characterized in that an annular flange vertical to the axis of the base body is fixedly connected on the outer wall of the tubular burner nozzle base body, close to the tail part of the tubular burner nozzle base body. In the burner nozzle of the suspension roaster, the annular flange vertical to the axis of the base body is fixedly connected at the outer wall of the tubular burner nozzle base body, near the tail part of the tubular burner nozzle basic body, which can effectively control the length of the burner nozzle extending into the roaster and lead flames to be centralized toward the center, thus effectively reducing the temperature of the cylinder wall of a combustion station, thereby reducing scar, improving the running capacity of the roaster system, reducing the damage to a refractory liner during the temperature raising and reducing processes of the roaster, reducing the consumption of coal gas, electric power and other power, and at the same time optimizing the ignition loss indexes.
Description
Technical field
A kind of burner of suspension roaster relates to a kind of improvement of nozzle structure of suspension roaster of aluminium oxide calcining process.
Background technology
Suspension roaster is a kind of aluminium oxide calcining technology of maturation, has the advantages that technology is simple, energy consumption is low, roasting quality is good.But the burning station problem that scabs is perplexing the steady production of roaster always, the gas-fired of burner is affected, the formation speed that scabs is very fast, and increasing, the piece that scabs afterwards drops, and scabs again, reciprocation cycle, cause the cylindrical shell tapering piece that scabs to stop up, influenced whirlwind tube rising air quantity and roaster blanking amount, rough sledding such as make roaster stop frequent and the time is long, burning station cylindrical shell burns out, consumes height, index is affected.Scab at present and adopt the shutdown maintenance blowing mostly, the method that cleaning scabs is kept production.
It is too high in barrel place, burning station temperature that the reason that causes burner to scab mainly is a burner, the aluminium oxide formation of luming under high temperature.At this situation, to adopt usually and manually disclose the way that scabs or the piece that scabs and drop and keep production, in case that scabbing of dropping stopped up is serious, just must shutdown maintenance when having influence on the roaster air quantity.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, provides a kind of and can effectively solve the scab burner of suspension roaster of problem of burner.
The purpose of this utility model is a specific implementation by the following technical programs.
A kind of burner of suspension roaster, the tubulose burner matrix and the connecting flange that is positioned at burner matrix tail end that comprise the spray orifice of termination band is characterized in that being connected with a ring flange vertical with its body axis near on the burner tubular matrix outer wall of tubulose burner matrix afterbody.
The burner of a kind of suspension roaster of the present utility model, what it is characterized in that described ring flange is 810-870mm apart from burner termination distance.
The burner of a kind of suspension roaster of the present utility model, be connected with a ring flange vertical near on the burner tubular matrix outer wall of tubulose burner matrix afterbody with its body axis, the length that the burner head can be stretched in the stove is controlled for effect ground, flame is concentrated to the center, effectively reduce burning station barrel temperature, scab thereby reduce, improved roaster system service ability, reduced roaster heat up, in the temperature-fall period to the damage of refractory lining, also reduced each side consumption such as coal gas, electric power, the index of igloss is simultaneously optimized.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a burner of the present utility model structural representation when using.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of burner of suspension roaster, comprise the termination band spray orifice tubulose burner matrix 1 and be positioned at the connecting flange 2 of burner matrix tail end, be connected with a ring flange 3 vertical near on the burner tubular matrix outer wall of tubulose burner matrix afterbody with its body axis; Described ring flange be 810-870mm apart from burner termination distance.
During operation, the burner of suspension roaster is installed on the suspension roaster 4, fixes with ring flange, the depth of suspension roaster burner is stretched in control, controls the discharging position of burner termination spray orifice, the control loop flange be 810-870mm apart from burner termination distance; Roaster operation observed have only a little scabbing, the labor cleaning is less, and the burner head does not have and burns out, damages phenomenon, does not influence the normal operation of roaster.
Claims (2)
1. the burner of a suspension roaster, the tubulose burner matrix and the connecting flange that is positioned at burner matrix tail end that comprise the spray orifice of termination band is characterized in that being connected with a ring flange vertical with its body axis near on the burner tubular matrix outer wall of tubulose burner matrix afterbody.
2. the burner of a kind of suspension roaster according to claim 1, what it is characterized in that described ring flange is 810-870mm apart from burner termination distance.
