Abstract
The utility model discloses an organic heat carrier furnace for radiation heating surfaces of vertical rising film type oil-cooled walls, which can reduce the flow resistance of organic heat carriers, reduce the power consumption of an organic heat carrier pump, the air leakage of a hearth and the consumption of steel materials, and alleviate the abrasion of tubes. A radiation heating surface of a vertical rising film type oil cooled wall is adopted for replacing a radiation heating surface of a horizontally-wound rising light tube oil-cooled wall, the vertical rising film type oil-cooled wall is formed by welding fins between a vertical oil-cooled wall tube and an adjacent oil-cooled wall tube thereof, the lower end of the vertical rising film type oil-cooled wall is connected with a lower header tank, and the upper end of the vertical rising film type oil-cooled wall is connected with an upper header tank. As a tube of the vertical rising film type oil-cooled wall is short and not provided with an elbow, the resistance is small, and the power consumption of a pump is less; as a film-type oil-cooled wall has no gap, a hearth is less in air leakage amount and high in temperature, thereby facilitating the reduction of incomplete combustion heat loss of fuels; the pitch of the tube is large, so that the consumption of steel materials is reduced; and the axial direction of the tube is parallel to the flow direction of flue gas, thereby alleviating the abrasion of the tube. The organic heat carrier furnace for radiation heating surfaces of vertical rising film type oil-cooled walls can be implemented by using chamber combustion, layer combustion and circulating fluidized bed combustion.
Description
Utility model relates to a kind of organic heat carrier furnace, especially can reduce the organic heat carrier flow resistance, reduces the power consumption of organic heat carrier pump, burner hearth leaks out and steel consumption, alleviates the vertical lifting membrane type oil cooling wall organic heat carrier furnace of tube wear.
Technical field
Organic heat carrier furnace can obtain very high oil temperature under the very low operating mode of operating oil pressure, for hot user provides temperature higher thermal source, be widely adopted in industries such as weaving, food, chemical industry, oil.
Background technology
Organic heat carrier furnace all mainly is made up of around rising light pipe oil cooling wall radiation heating-surface and convection heating surface burner, level at present.The low temperature organic heat carrier that returns from hot user;, the organic heat carrier pump at first gets into the convection heating surface heating after boosting through inlet collection case; Temperature raise the back through outlet collection case entering level around rising light pipe oil cooling wall radiation heating-surface, deliver to hot user through outlet collection case after being heated to design temperature.Though level around rising light pipe oil cooling wall radiation heating-surface organic heat carrier furnace, can be heated to organic heat carrier the temperature of setting, has following shortcoming:
1. level is long around the light pipe radiation heating-surface pipeline that rises, and elbow is many, and the flow resistance of organic heat carrier is big, causes the organic heat carrier pump lift high, and power consumption is many.
2. though level is respectively enclosed pipe and closely arranged around rising light pipe radiation heating-surface, but still has the slit, because of burner hearth is a negative pressure, cold wind is prone to the burner hearth that bleeds, and fire box temperature reduces, and causes the non-complete combustion of fuel heat loss to increase.
3. respectively enclose pipe because of level around rising light pipe radiation heating-surface and closely arrange, steel consumption is big.
4. when adopting the circulating fluid bed organic heat carrier stove, because of flue gas material concentration in the burner hearth is very high, material is very serious around the tube wear that rises to level; In order to alleviate wearing and tearing, be forced in dilute-phase zone radiation heating-surface tube surface and lay resistant to elevated temperatures scuff-resistant coating, not only cost improves; And because of the decline of thermal resistance increase heat transfer efficiency; For organic heat carrier is heated to design temperature, radiation heating-surface is long-pending to be increased with the steelframe height, causes steel consumption to rise.
The utility model content
The purpose of the utility model provides and a kind ofly can reduce the organic heat carrier flow resistance, reduces the power consumption of organic heat carrier pump, burner hearth leaks out and steel consumption, alleviates the organic heat carrier furnace of tube wear.
The purpose of the utility model is achieved in that employing vertical lifting membrane type oil cooling wall radiation heating-surface, and substitution level is around rising light pipe radiation heating-surface, and the lower end of vertical lifting membrane type oil cooling wall is connected with the next part case, and the upper end is connected with upper collecting chamber.Vertical lifting membrane type oil cooling wall is welded by the fin between vertical oily cold wall pipe and the adjacent oily cold wall pipe.
Description of drawings
Fig. 1 is the profilograph of the utility model, and Fig. 2 is the A-A cutaway view.1. low temperature organic heat carriers, 2. organic heat carrier pumps, 3. convection heating surfaces inlet collection case, 4. convection heating surfaces, 5. convection heating surfaces outlet collection case, 6. membrane type oil cooling wall next part casees, 7. vertical lifting membrane type oil cooling wall radiation heating-surfaces, 8. membrane type oil cooling wall upper collecting chambers, 9. high temperature organic heat carriers, 10. furnace walls, 11. burners, 12. oily cold wall pipe 13. fins 14. burner hearths among the figure.
The specific embodiment
The low temperature organic heat carrier 1 that returns from hot user;, organic heat carrier pump 2 gets into convection heating surface 4 heating after boosting through convection heating surface inlet collection case 3; After raising, temperature collects the next part case 6 that case 5 gets into membrane type oil cooling wall through the convection heating surface outlet; Rise along vertical lifting membrane type oil cooling wall radiation heating-surface 7, get into membrane type oil cooling wall upper collecting chamber 8 after the absorption burner hearth 14 flame radiation heat, deliver to hot user from the high temperature organic heat carrier 9 that reaches design temperature that membrane type oil cooling wall upper collecting chamber comes out.Grate firing, chamber combustion and circulating fluid bed organic heat carrier stove all can adopt the utility model.
Owing to adopted such scheme, the utlity model has following advantage:
1. short because of vertical lifting membrane type oil cooling wall radiation heating-surface pipeline, there is not elbow, the flow resistance of organic heat carrier is little, and the organic heat carrier pump lift reduces, and power consumption reduces.
2. vertical lifting membrane type oil cooling wall good seal performance, the burner hearth inleakage is few, and fire box temperature is high, helps reducing the non-complete combustion of fuel heat loss.
3. after adopting membrane type oil cooling wall, the pitch of oily cold wall pipe increases, and the steel consumption amount of radiation heating-surface is descended.
4. vertical lifting oil cooling wall pipe is axially parallel with the flow direction of flue gas; Flying dust or material alleviate the wearing and tearing of tube wall in the flue gas; Do not lay under the situation of fire resistant wear prevention layer at Circulation fluidized-bed furnace dilute-phase zone radiation heating-surface tube surface, can the long-term safety operation.Because of thermal resistance reduces, heat transfer efficiency improves, and can reduce the area of circulating fluid bed organic heat carrier stove radiation heating-surface and the height of steelframe, and the consumption of steel is further descended.
The utility model has been created condition for the circulating fluid bed organic heat carrier stove that manufacturing dilute-phase zone radiation heating-surface pipe does not lay the fire resistant wear prevention layer.
