Abstract
The invention discloses a regular hexagon rotary cement kiln surface heat recovery device. The regular hexagon rotary cement kiln surface recovery device comprises a water-cooling wall and an outer cover, and is characterized in that the water-cooling wall and the outer cover are regular-hexagon-shaped, the water-cooling wall is arranged on the periphery of a rotary cement kiln, the outer cover is arranged on the periphery of the water-cooling wall, gaps are remained between the outer cover and the water-cooling wall and between the water-cooling wall and the surface of the rotary cement kilnto form an inner ventilating duct and an outer ventilating duct which are communicated, and the upper portion and the lower portion of the outer cover are respectively provided with a ventilating opening. Because the regular-hexagon-shaped outer cover and the regular-hexagon-shaped water-cooling wall are adopted, difficulties and costs are greatly reduced in the manufacturing and installment process. Air entering ventilating ducts forms backflow because of geometry reasons, not only ensures that heat-exchanging effects on the surfaces of the water-cooling wall and the rotary cement kiln are enhanced, stay time of the air inside the ventilating ducts is longer, and accordingly heat recovery effects are strengthened, and more heat is recovered, but also facilitates regular operations of therotary cement kiln.
Description
Technical field
The present invention relates to a kind of device for recovery cement rotary kiln surface heat, belong to the heat recovery technology field.
Background technology
Cement industry always is a highly energy-consuming, the industry of high pollution, and therefore traditional cement rotary kiln has very big energy-saving potential.Cement rotary kiln when work surface temperature very high, most of heat all scatters and disappears with radiation mode, has caused the waste of the energy like this and to the acceleration consume of equipment.
The profile of existing cement rotary kiln surface heat reclaim unit generally all is that the shape according to cement rotary kiln designs rounded or semicircle being centered around on the cement rotary kiln of the water-cooling wall of heat reclaim unit.So not only cause some difficulties to making the installation water-cooling wall, and cold air is short at the rotary kiln surface stroke, the time of staying is short, thus the heat exchange weak effect, the backheat rate is low, and effect is not good enough.
Summary of the invention
The present invention is directed to the deficiency that existing cement rotary kiln surface heat recovery technology exists, provide a kind of and can reduce the regular hexagon cement rotary kiln surface heat reclaim unit of manufacture difficulty being installed, improving effectiveness of regenerator.
Regular hexagon outer cover cement rotary kiln of the present invention surface heat reclaim unit, adopt following technical scheme:
This device, comprise water-cooling wall and outer cover, water-cooling wall and outer cover all are regular hexagon, water-cooling wall is arranged on the periphery of cement rotary kiln, outer cover is arranged on the periphery of water-cooling wall, all has the gap between outer cover and the water-cooling wall and between water-cooling wall and the rotary kiln surface, ventilating duct and separate ventilation road in forming, interior ventilating duct and separate ventilation road are connected, and respectively are provided with a ventilating opening in the above and below of outer cover.
The cold air that ventilating opening enters under working medium in water-cooling wall and the process is lowered the temperature to rotary kiln surface when absorbing the heat of rotary kiln surface, and its surperficial temperature is remained within the metastable scope.When the rotary kiln surface is lowered the temperature, also reclaim this part heat, not only realized the recycling of energy, also reduced the consume of equipment.
The present invention adopts regular hexagon outer cover and cold water wall; compared to traditional circular or semicircle outer cover and water-cooling wall; not only in making installation process, greatly reduce difficulty and cost; and in the advantage that self is also arranged aspect heat exchange and the reduction equipment loss; the air that enters in the ventilating duct refluxes owing to geometric reasons forms on the position at orthohexagonal six angles; not only feasible heat exchange effect with water-cooling wall and rotary kiln surface is strengthened but also the time of staying in ventilating duct also lengthens; strengthened the heat recovery effect like this; realize the recovery of more heats, better protection equipment.
Description of drawings
Accompanying drawing is structural representation of the present invention.
Among the figure: 1, go up ventilating opening, 2, water-cooling wall, 3, rotary kiln, 4, outer cover, 5, ventilating opening down, 6, interior ventilating duct, 7, the separate ventilation road.
The specific embodiment
As shown in drawings, regular hexagon cement rotary kiln of the present invention surface heat reclaim unit comprises outer cover 4 and water-cooling wall 2, and outer cover 4 and water-cooling wall 2 all are regular hexagon.Water-cooling wall 2 is arranged on the periphery of cement rotary kiln 3, has the space between water-cooling wall 2 and the cement rotary kiln 3, ventilating duct 6 in forming.Outer cover 4 is arranged on the periphery of water-cooling wall 2, has the space between between outer cover 4 and the water-cooling wall 2, forms separate ventilation road 7.Interior ventilating duct 6 and separate ventilation road 7 are connected.Ventilating opening on both sides are respectively equipped with up and down 1 and 5, two ventilating ducts of following ventilating opening at outer cover 4 can link to each other with a blower fan respectively, by descending ventilating opening 5 inspiration cold airs, by last ventilating opening 1 discharge hot-air.Water-cooling wall 2 can be made two parts symmetry and link together, and ventilating duct 6 and separate ventilation road 7 are connected in making by the gap between two parts.
When rotary kiln 3 work, its surface temperature is higher, can absorb the radiations heat energy on rotary kiln 3 surfaces when placing this moment cold fluid working medium in the water-cooling wall 2 of rotary kiln 3 peripheries to flow through rotary kiln 3 peripheral spaces, and the cold fluid in the water-cooling wall 2 is heated the back and collects.Meanwhile, cold air enters interior ventilating duct 6 between water-cooling wall 2 and the rotary kiln 3 and the separate ventilation road 7 between outer cover 4 and the water-cooling wall 2 through following ventilating opening 5, be heated when flow through rotary kiln 3 and water-cooling wall 2 surperficial, absorb the heat on their surfaces, the air trapping after the heating is used.
