Abstract
The utility model discloses a kind of jacket type blind pipe electric heater.It comprises the pressure vessel with import and outlet and the terminal box being positioned at pressure vessel one end, the end face of pressure vessel fixedly mounts tube sheet flange, tube sheet flange fixed arrangement has many blind pipes, the upper end of every root blind pipe connects terminal box, lower end extend in pressure vessel, all be inserted with electric heating tube bank in every root blind pipe, the center of some electric heating tube bank is provided with temperature transducer.After adopting above-mentioned structure, owing to directly inserting electric heating tube bank in blind pipe as heater element, make temperature transducer be located immediately in blind pipe, on the one hand simultaneously, thermometric accuracy is effectively improved, solve the inaccurate technical barrier of traditional structure thermometric, in addition on the one hand, in repair and maintenance process, directly can change temperature transducer, pressure vessel need not be removed again, substantially reduce replacing construction, improve replacing efficiency.
Description
Technical field
The utility model relates to a kind of electric heater unit, specifically a kind of jacket type blind pipe electric heater.
Background technology
Traditional industrial heat adopts circulation heater to heat material usually, to meet technique related request.Heater element-the heating tube of circulation heater directly and medium contact, Long-Time Service heating tube tube wall can produce corrosion phenomenon, because heating tube thickness of pipe wall is thinner, be easy to cause shell damaged, heating object material is caused to leak, in addition, the heating tube of circulation heater, tube sheet flange and Socket welding load are connected together, solder joint is many, can form larger welding stress, easily produce weld crack, cause and leak and make equipment failure, and heater element damages, and need relief and emptying material during maintenance, maintenance of equipment is extremely not convenient.
At present, it is domestic that to disclose one section of patent No. be 201220232709.0, name is called the utility model patent of " the isothermal thermal field electric heater of interior radiation ", it comprises container, be arranged on the end flanges on container, flange be fixedly welded with the many heating tubes be inserted in container, insert heating wire in heating tube as heater element, heating tube is connected with terminal box, and terminal box is provided with cable access, fills nitrogen mouth; Heating tube outer wall is provided with over-temperature sensor, this structure has good high temperature high voltage resistant, corrosion resistance, but because over-temperature sensor is fixedly mounted on heating tube outer wall, only measure heating tube tube wall temperature, and can not Measurement accuracy heating tube internal temperature; In addition, make maintenance, safeguard, change very inconvenient, when changing in components and parts processes, whole container must be removed, maintenance, safeguard, change inconvenience, extend replacing construction, reduce replacing efficiency.
Summary of the invention
The technical problems to be solved in the utility model be to provide one not only have high temperature high voltage resistant, corrosion resistance but also thermometric accurately, repair and replacement conveniently jacket type blind pipe electric heater.
In order to solve the problems of the technologies described above, jacket type blind pipe electric heater of the present utility model, comprise the pressure vessel with import and outlet and the terminal box being positioned at pressure vessel one end, the end face of pressure vessel fixedly mounts tube sheet flange, tube sheet flange fixed arrangement has many blind pipes, and the upper end of every root blind pipe connects terminal box, and lower end extend in pressure vessel, all be inserted with electric heating tube bank in every root blind pipe, the center of some electric heating tube bank is provided with temperature transducer.
Between each blind pipe, supporting bracket is installed to fix.
Described terminal box is provided with cable access, fills nitrogen mouth.
Described electric heating tube bank is arranged by some U-shaped electrothermal tubes and forms cage construction, and temperature transducer inserts the center of electric heating tube bank.
Strutting piece is provided with between described electric heating tube bank.
The top of each described electric heating tube bank is connected with blind pipe end.
After adopting above-mentioned structure, owing to directly inserting electric heating tube bank in blind pipe as heater element, make temperature transducer be located immediately in blind pipe, on the one hand simultaneously, thermometric accuracy is effectively improved, solve the inaccurate technical barrier of traditional structure thermometric, in addition on the one hand, in repair and maintenance process, directly can change temperature transducer, pressure vessel need not be removed again, substantially reduce replacing construction, improve replacing efficiency.
