Abstract
The utility model relates to an electric heating device, in particular, relates to an electric heating element used for heating a gas flowing in a pipeline and a pipeline electric heater adopting the electric heating element. The electric heating element comprises a cylinder-shaped base body made of refractory materials. Longitudinal mounting grooves are uniformly distributed at the outer cylindrical surface of the base body; a helical resistance wire is reciprocatingly installed in each mounting groove; and two ends of the resistance wire are provided with lead-out electrodes. According to the electric heating element, the longitudinal mounting grooves at the outer cylindrical surface of the base body can be utilized to compactly arrange the resistance wire; and the electric heating element is advantageous in compact structure, less occupied space, effectively improved effective density and heating power.
Description
Technical field
The utility model relates to a kind of electric heater unit, specifically a kind of for the gas that flows in the pipeline is heated electric heating element and the electric heater for pipeline that adopts this electric heating element.
Background technology
In traditional electric heater for pipeline, its electric heating element adopts electrothermal tube usually, because the structure of electrothermal tube itself is complicated, not only manufacturing cost is higher, and its space that takies is larger, and correspondingly the effective density of electric heating element is less; Because electrothermal tube is subjected to the restriction of its sheathing material, size and surface loading parameter, be difficult in less space, realize larger heating power simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of simple in structure, cost is low, can improve electric heating element density in the electric heater for pipeline, can realize the electric heating element of larger heating power in less space and adopt the electric heater for pipeline of this electric heating element.
Electric heating element of the present utility model includes the columned matrix of being made by refractory material, is evenly distributed with longitudinally mounting groove on the external cylindrical surface of matrix, and a spiral helicine resistance wire back and forth is placed in each mounting groove, and the two ends of resistance wire arrange extraction electrode.
Described matrix is comprised of the columniform base unit of multistage, and the base unit center arranges jack hole, and a cross-under bolt passes jack hole each base unit is connected to coaxial integral body.
Electric heater for pipeline of the present utility model comprises the housing of one section tubulose, and the housing two ends are provided with the adpting flange that is connected with pipeline, axially are provided with a plurality of above-mentioned electric heating elements in housing; The lower end of each electric heating element is fixedly mounted on the mounting base that is positioned at housing one end, and the top of each electric heating element is provided with the bus electrode that is connected with each electric heating element extraction electrode; Be provided with terminal box on the described housing, be provided with the power supply terminal that is connected with bus electrode in the terminal box.
Electric heating element of the present utility model can utilize the vertical mounting groove on its matrix external cylindrical surface to arrange to high-density resistance wire, and its compact conformation, space hold are little, has effectively improved electric heating element effective density and the heating power of electric heater for pipeline.The electric heater for pipeline of traditional electrical heat pipe-type just can be realized the heating power of 800KW usually in the housing of 1 meter of caliber, length 4-5 rice; And can make electric heater for pipeline in the housing of diameter 700mm, length 1.3m, realize the heating power of 1200KW after adopting structure of the present utility model, simultaneously its uniform heat distribution, heating effect are good.
