Abstract
The gas burning nozzle for cathode roasting furnace has a connecting pipe, a base, a nozzle pipe and a nozzle head connected successively, and the base has the inner hole with lower end connected to the nozzle pipe and upper end connected to the containing pipe. The present invention has low cost, long service life, capacity of reach homogeneous combustor temperature, high heat energy utilizing rate and small heat shock to the furnace.
Description
Technical field
The present invention relates to a kind of carbon cathode process units, especially a kind of cathode roasting furnace gas burner nozzle.
Background technology
At present, to uniform temperature, this realizes by formula cathode baking furnace with cover that generally considerable cathode baking furnace adopts gaseous fuel (natural gas, coal gas) with the cathode block roasting in the carbon cathode production requirement.In the prior art general with the furnace inner space under the cathode baking furnace bell (gas well) as the combustion chamber, on bell with common steel tube or heat resisting pipe as the fuel gas inlet pipe.Because the furnace inner space extreme temperatures under the bell is simultaneously because the bitumen flue gas that cathode block discharges produces corrosion to steel pipe.The consequence that causes like this is: steel pipe gross distortion corrosion at high temperature on the one hand, and the life-span is extremely short; On the other hand, steel pipe can not make long enough, cause the localized hyperthermia at next-door neighbour's bell place in the furnace chamber, make in the stove upper and lower temperature difference bigger.This not only influences the roasting quality of cathode block, and has wasted the wide variety of materials and the energy, simultaneously also because the frequent fuel gas inlet pipe of changing has increased the workload of moving and safeguarding.Obviously, the fuel gas inlet of existing cathode baking furnace is not ideal enough.
Summary of the invention
The objective of the invention is to, a kind of cathode roasting furnace gas burner nozzle is provided, this burner implementation cost is lower, high life, and chamber temperature is even, constant product quality, heat energy utilization rate height, little to the thermal shock of furnace chamber and bell, operation and maintenance cost are low.
Technical scheme of the present invention: the lower end of jet pipe (2) is connected with shower nozzle (1), and the top of jet pipe (2) is connected with the bottom of nozzle belt (4), and the bottom endoporus of base (3) is connected with jet pipe (2), and the top endoporus of base (3) is connected with nozzle belt (4).
Described cathode roasting furnace gas burner nozzle, shower nozzle (1) all adopts high temperature ceramic material with jet pipe (2).
The pipeline section partial-length that aforesaid jet pipe (2) stretches in the furnace chamber is 400mm～1000mm.
The nozzle diameter of aforesaid shower nozzle (1) is 9mm～30mm, and converging transition length is 20mm～100mm, and tapering is 10o～15o, and the internal diameter of jet pipe (2) is 15mm～80mm.
The material of aforesaid nozzle belt (4) is a heat resisting steel.
Aforesaid shower nozzle (1) adopts with jet pipe (2) and is threaded, and all clogs ceramic fibre (8) in the contact-making surface and in the thread gaps.
The top of aforesaid base (3) is connected by bolt (5) with nozzle belt (4), and the bottom tube face of nozzle belt (4) is pressed in the exterior marginal tube upper surface of jet pipe (2), and the exterior marginal tube lower surface of jet pipe (2) is pressed in endoporus upper end, base (3) bottom.
Filling ceramic fibre (8) in the space that above-mentioned nozzle belt (4), base (3) and jet pipe (2) form.
The top of above-mentioned base (3) is connected by bolt (5) with nozzle belt (4).
Compared with prior art, the present invention adopts high temperature ceramic material, corrosion-resistant: long service life, high temperature resistant: as can to make burner go deep into inside, combustion chamber, make chamber temperature even, temperature schedule is reasonable, constant product quality, heat energy utilization rate height, little to the thermal shock of furnace chamber and bell, operation and maintenance cost are little, improve working environment, implementation cost is low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Embodiment: the structure of cathode roasting furnace gas burner nozzle as shown in Figure 1, shower nozzle 1 all adopts high temperature ceramic material with jet pipe 2, the lower end of jet pipe 2 is adopted with shower nozzle 1 and is threaded, all clog ceramic fibre 8 in the contact-making surface and in the thread gaps, the pipeline section partial-length that jet pipe 2 stretches in the furnace chamber is 500mm; The nozzle diameter of shower nozzle 1 is 11mm, and converging transition length is 25mm, and tapering is 13.5o, and the internal diameter of jet pipe 2 is 17mm; Base 3 adopts heat-resisting cast iron to make, it is connected by bolt 5 with nozzle belt 4, the material of nozzle belt 4 is a heat resisting steel, the bottom tube face of nozzle belt 4 is pressed in the exterior marginal tube upper surface of jet pipe 2, the exterior marginal tube lower surface of jet pipe 2 is pressed in endoporus upper end, base 3 bottom, filling ceramic fibre 8 in the space that nozzle belt 4, base 3 and jet pipe (2) form.
During work, natural gas continues to enter jet pipe 2 after introducing nozzle belt 4, enter the converging transition of shower nozzle 1 at last, quicken the rotation ejection under pressure, because the effect of converging transition, conical hollow appears in the air-flow of ejection, fully mixes after-combustion with oxygen in the inverted draft in the stove.
