Description
Technical field
The utility model relates to a kind of heater, and particularly a kind of heat carrier pipe internal-circulation type heater, belongs to technical field of heat exchange equipment.
Background technology
When environmental requirement is more and more strict at home, various with coal by the heating boiler of medium is substituted by combustion gas and apparatus for fuel heating gradually, electrical heating Oil Guide stove is at present the common heat transmission equipment of one of heat carrier with oil, the electric heating conduction oil furnace that current domestic production uses all adopts series connection many groups cluster type electric heater for heating in fuel tank, concrete structure as shown in Figure 1, in Fig. 1, 81 is binding post, 82 is heating tube, 83 is fuel tank, 84 is heat-insulation layer, take heat medium oil and be circulated to heating equipment working face through hot oil pump, in use there is following defect in this electrical heating Oil Guide stove, one is that deep fat consumption is large, energy consumption is higher, two is under forced circulation pressure, a kind of line heterogeneous is formed in fuel tank, make conduction oil forming section dead angle, cause thermal loss, arrow in accompanying drawing 1 represents oil flow direction and illustrates this phenomenon, and this heater in use temperature control deviation is comparatively large, to be usually greater than ± 3 DEG C, in production practices, to need a kind of electrical heating Oil Guide stove of efficient stable.
Summary of the invention
The purpose of this utility model is the defect overcoming above prior art, provides the electrical heating Oil Guide stove that a kind of energy consumption is low, efficiency is high.
For realizing the purpose of this utility model, the technical scheme that the utility model adopts is: heat carrier pipe internal-circulation type heater, comprise electric heating tube, multiple U-shaped pipe is adopted mutually to connect, described electric heating tube sealing is arranged in U-shaped pipe, heat carrier is entered by the U-shaped pipe of pipeline from front end, pipeline is flowed out through to heating equipment from the U-shaped pipe of end, oil pipe mouth will be passed in and out and form closed circuit with hot oil pump and heating equipment pipeline UNICOM respectively, further, described electric heating tube is from the open-ended middle insertion U-shaped pipe on U-shaped pipe both sides, between electric heating tube and U-shaped tube end, flange seal is set, electric heating tube is connected with controller, further, described circulation line is connected with heating carrier supplemental tank.
the positive Advantageous Effects that the utility model has is: the utility model creates obvious energy-saving effect in the raising of the thermal efficiency, heater of the present utility model operationally can make conduction oil cyclic process without dead angle, and it is few with oil, firing rate is fast, the thermal efficiency improves, between heating tube and oily carrier, heat exchange is good, heat loss is little, facts have proved through working online, the utility model improves 20%-30% compared with the cluster type heater thermal efficiency in current case, oil temperature can accurately control at about ± 1 DEG C by this device, thus ensure the process stabilizing of heating equipment, the manufacture of this apparatus structure is simple, process without the need to large-scale precision equipment, relatively cheap.
Accompanying drawing explanation
