Description
Technical field
The utility model belongs to technical field of burner, and what relate generally to is a kind of water-cooled heat-accumulation combustor.
Background technology
Steel mill is to adopt self-preheating type ladle baking facility, heat storing type ladle baker to come the heated baking steel ladle mostly at present.Wherein the heat accumulating type roaster can make baking temperature of steel ladle reach more than 1100 ℃, helps improving the internal soundness of steel billet, has remarkable economic efficiency.It has adopted the high frequency reversal valve, makes high-temperature waste gas and combustion air and coal gas alternately pass through in ceramic heat storage body, carries out sufficient heat exchange each other, combustion air temperature is reached about 900 ℃, increase its heat content, realize smooth combustion, reach the purpose of abundant conserve energy.Though common heat-storage type burner used on the heat storing type ladle baker has improved burning capacity, but because the material material that the burner bottom and the bore place that fires are used is 1Cr18Ni9Ti, the high temperature that can bear is about 900 ℃, and can reach about 1200 ℃ by the flame temperature behind the common heat-storage type burner this moment, long-time continuous high-temperature operation meeting repeatedly causes its bottom that is contacted with clad and crater position well damage, influence its service life, be generally 10～12 months.
Summary of the invention
The purpose of this utility model promptly produces thus, a kind of water-cooled heat-accumulation combustor is provided, the burner bottom that solution causes because of ignition temperature is too high and the flimsy problem of bore pipe that fires, effectively reduce the body temperature on the burner bottom and the bore pipeline that fires, prolong the service life of burner.
The technical scheme that the purpose of this utility model is taked is: on the architecture basics of existing heat-storage type burner, bottom and crater pipeline at the accumulation of heat casing are provided with the recirculated water cooling mechanism that is made of water inlet pipe, outlet pipe and cooling jacket, water inlet pipe and outlet pipe are located at the left and right sides of cooling jacket respectively, cooling jacket is airtight loop configuration, the lower surface of accumulation of heat casing is close in its upper surface, and the crater pipeline is close at annular position.
The utility model is provided with recirculated water cooling mechanism by bottom and the crater at heat-storage type burner, has overcome the burner bottom and the fragile burner drawback in service life that influences of crater pipeline that cause because of ignition temperature is too high.Make it realize that common heat-accumulation combustor is efficient, in the energy-saving and environmental protection, utilize recirculated water cooling mechanism effectively to reduce the body temperature of burner bottom and crater pipeline, make it to fall and reach about 900 ℃ of the high temperature that body can bear, reach 36 months the service life of improving burner thus.
Description of drawings
Fig. 1 is the structure principle chart of existing common heat-accumulation combustor.
Fig. 2 is a structural representation of the present utility model.
Among the figure: 1, Gas Pipe, 2, the accumulation of heat casing, 3, the crater pipeline, 4, heat storage, 5, air hose, 6, outlet pipe, 7, water inlet pipe, 8, cooling jacket.
The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
Figure 1 shows that known common heat storing type ladle baker, it is reached by two heat-storage type burner A, B, gas transfer valve C, gas supply system G, combustion air feed system D is made up of the formed air inducing smoke evacuation system of air-introduced machine E F.Heat-storage type burner A, B occur in pairs, when the combustion air of a burner A was preheated after-combustion by heat storage, another burner B was used for smoke evacuation, heating heat storage in smoke evacuation, after this heat storage was fully heated, gas transfer valve C action made the system reverse operation.So just finish a commutation cycle.So move in circles, realize improving the purpose of ignition temperature and energy savings.The high alumina refractories of in the clad of ladle baking facility, casting, clad is provided with the accumulation of heat apparatus for baking, and the waste heat that produces when utilizing baking is preheated to 900-1000 ℃ with combustion air.It can be mixed more fully with coal gas and burning more fully, thereby improve the temperature of combustion flame further.Realization reaches the effect of ideal temperature with the less energy and faster speed.
As shown in Figure 2: the Gas Pipe 1 of burner A and B is positioned at the top of accumulation of heat casing 2 and crater pipeline 3, and accumulation of heat casing 2 is square casings, except that with a side that air hose 5 connects all the other five sides be provided with heat-insulation layer.All put several layers of cuboid ceramic honeycomb heat storage 4 in accumulation of heat casing 2 inner chamber right side levels and vertical direction, can make it under the work of exhausting smoke evacuation system, to save waste-gas heat in the ladle (thereby the number of plies can be defined as two-layer or three layers of change casing size dimension according to needed burning capacity).A side that is positioned at heat storage 4 at accumulation of heat casing 2 is established air hose 5, and being linked by conical shell and flange constitutes.Bottom and crater pipeline 3 positions at accumulation of heat casing 2 are provided with the recirculated water cooling mechanism that is made of water inlet pipe 7, outlet pipe 6 and cooling jacket 8, water inlet pipe 7 and outlet pipe 6 are located at the left and right sides of cooling jacket 8 respectively, cooling jacket 8 is airtight loop configuration, the lower surface of accumulation of heat casing 2 is close in its upper surface, and annular position is close on the crater pipeline 3.During use, utilize cooling water self pressure to enter in the cooling jacket 8 from another delivery port 6 outflows (being depicted as water (flow) direction) as the figure arrow from the water inlet pipe 7 of a side, take away the heat of burner bottom and crater, reach cool burner bottom and crater body temperature, make it be reduced to about 900 ℃ of the high temperature that can bear, the purpose that prolongs the service life of burner.
Present embodiment describes in detail operation principle of the present invention with air feed system, coal gas system and circulating water cooling system:
