Description
Technical field
The utility model relates to a kind of manufacturing technology field of electric heater, particularly a kind of manufacturing technology field of industrial anti-explosion electric heater.
Background technology
Conventional fluid formula anti-explosion electric heater is applicable to flow media in the pipeline is directly heated up, heats that its specific high efficiency and heat radiation principle is to adopt the cluster type electric heating tube to be contained in the pressure vessel, and medium is taken away the heat that heating distributes along designed path; It is for the explosion-proof place that is in petrochemical process equipment, and the fluid-type anti-explosion electric heater is because the restriction of structure causes the heat medium time very short, and is low to the heating quality of flow media; The medium heating is inhomogeneous, and it has influenced explained hereafter, especially heats traditional liquid; The dead angle of heater structure is more obvious, and for some similar electric heater, its heat medium time is very short; That have even have only several seconds; The dead angle of its existence is more serious, and shell side is also shorter, and these heaters have influenced the heating quality of flow media greatly.
Summary of the invention
The utility model provides a kind of fluid anti-explosion electric heater, and purpose is to solve weak point heat time heating time of the existing explosion-proof heater fluid medium of fluid, and heating quality is not high, heats uneven defective.
The utility model comprises line box body, pressure container body, and said line box body is connected the upper end of said pressure container body through flange, between said line box body and pressure container body, the electric heating tube installing plate is set; On said electric heating tube installing plate, be uniformly distributed with electric heating tube; On said line box body, the cable mouth is set, coaxial first cylindrical shell, second cylindrical shell, the 3rd cylindrical shell of being provided with on said pressure container body lower shoe, said second cylindrical shell is arranged on outside said first cylindrical shell; Said the 3rd cylindrical shell is arranged on outside said second cylindrical shell; Said each electric heating tube is distributed on respectively between said first, second, third cylindrical shell, and the height of said first cylindrical shell is lower than second cylindrical shell, and the height of said second cylindrical shell is lower than the 3rd cylindrical shell; In the bottom of said first cylinder lateral wall medium is set and enters the hole; In the bottom of said the 3rd cylindrical shell medium is set and enters the hole, in said first cylindrical shell, outlet is set, the upper end of said outlet is higher than second cylindrical shell and is lower than the 3rd cylindrical shell; The below that the pressure container body lower shoe is arranged in said pressure container body is passed in the lower end of said outlet; Top at said pressure vessel body sidewall is provided with inlet tube, and the position of said inlet tube is lower than the upper end of the 3rd cylindrical shell, in the bottom of said outlet blow-off pipe is set.
When the utility model uses; Fluid media (medium) gets in the pressure container body from inlet tube; Fluid media (medium) flows into earlier between the 3rd cylindrical shell and the pressure container body, and the medium of fluid media (medium) through the 3rd cylindrical shell bottom advances orifice flow and go between second cylindrical shell and the 3rd cylindrical shell, along with the rising of fluid level then; Fluid media (medium) covers second cylindrical shell and gets between second cylindrical shell and first cylindrical shell; Get into around here the medium of fluid through the first cylindrical shell bottom and enter the hole and get in first cylindrical shell, along with the rising of whole liquid level in the pressure vessel, the upper end that the fluid media (medium) liquid level is higher than outlet gets in the outlet flows out in succession; The utility model adopts the cylinder of a plurality of height shell sides in pressure container body, and has medium in the bottom of alternate cylinder and enter the hole, and fluid media (medium) flows through the gap between all cylindrical shells; Just flow out from outlet at last, fluid media (medium) has passed through one section long flow process like this, and get a promotion its heat time heating time greatly; Heating quality is improved equally; Between adjacent two cylindrical shells electric heating tube is arranged all, because of fluid media (medium) time of staying in pressure container body longer, so electric heating tube can fluid medium heat fully; And the radial distance of fluid media (medium) and electric heating tube is shorter, and it is heated more even; Long flow process adds a plurality of electric heating tubes, makes heating not have dead angle, homogeneous heating; And this cold bag heat structure has been practiced thrift electric weight; The existing traditional vertical of the aspect ratio of this heater electric heater that flows is low about 2/3rds, has practiced thrift steel greatly, and cost has been practiced thrift in the also corresponding shortening of the length of electric heating tube.
