Description
Technical Field
The utility model relates to a heating furnace for asphalt production belongs to heating furnace technical field.
Background
In the asphalt production process, asphalt needs to be heated. The heating furnace is applied to various industrial fields such as petroleum, chemical engineering and the like. The heating furnace in the existing heating process facility can not form temperature increment, has low heat transfer efficiency and causes poor product quality.
SUMMERY OF THE UTILITY MODEL
According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: overcomes the defects of the prior art, provides a heating furnace for asphalt production, improves the heat transfer efficiency and further improves the product quality.
Heating furnace is used in pitch production, including the furnace body, be equipped with heating coil and combustor in the furnace body, heating coil connects the fluid access & exit, heating coil set up directly over the combustor, heating coil includes inside and outside nested outer coil pipe and the interior coil pipe together, outer coil pipe and interior coil pipe are the toper heliciform.
The medium flows through the heating coil of the heating furnace, the double-layer heating coil is nested inside and outside and is arranged right above the burner, and the inner heating coil and the outer heating coil adopt a conical spiral shape, so that the heat transfer area is increased, and the heat energy utilization efficiency is greatly improved.
The furnace body is externally provided with a heat insulation material, so that the temperature in the furnace is further increased, and the heating efficiency is improved.
The furnace body is provided with two layers of heat insulation materials, namely an outer heat insulation layer and an inner heat insulation layer, and adopts double-layer heat insulation.
The outer heat-insulating layer is rock wool felt, and the inner heat-insulating layer is a magnesium-aluminum radiation heat-insulating material. The rock wool felt has good incombustibility and good heat-insulating property. The light magnesium-aluminum radiation heat-insulating material has the shielding functions on radiation, conduction and convection heat transfer modes, particularly has very high shielding on heat radiation, and has good heat-insulating property.
Preferably, the two ends of the heating coil are welded with connecting flanges, so that the heating coil is convenient to connect.
Compared with the prior art, the utility model beneficial effect who has is:
heating furnace is used in pitch production, the nestification is in the same place inside and outside outer coil pipe and the interior coil pipe, increases the space utilization in the stove, effectively improves heating efficiency. The medium is heated in a large area, so that the medium is heated more quickly and uniformly, and the heating effect is good. The temperature is optimized and improved, the temperature difference is shortened, and the product quality is more stable. And connecting flanges are welded at two ends of the heating coil, so that the butt joint is simpler.
