Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the embodiment of the present invention provides a heating system for flowing liquid, which includes a heating body 11 and an electromagnetic induction coil 12.
The electromagnetic induction coil 12 is capable of generating an alternating magnetic field, and the heating body 11 induces the alternating magnetic field. The heating body 11 is placed in an alternating magnetic field, and when the alternating magnetic field is generated, the heating body 11 induces the alternating magnetic field. The flowing liquid flows through the heating body 11, the heating body 11 induces an alternating magnetic field to generate alternating current to enable the heating body 11 to generate heat energy, and the heat energy directly heats the flowing liquid.
The alternating magnetic field is generated by the electromagnetic induction coil 12, specifically, after the electromagnetic induction coil 12 is powered on, the electromagnetic induction coil 12 generates the alternating magnetic field, and when the electromagnetic induction coil 12 is not powered on, the electromagnetic induction coil 12 does not generate the alternating magnetic field. When the electromagnetic induction coil 12 is switched from power-on to power-off, the induced alternating magnetic field generated by the power-on disappears after the power-off.
In the present embodiment, the heating body 11 is an object composed of a ferromagnetic material, which is capable of inducing an alternating magnetic field.
The heating body 11 generates an alternating current upon sensing an alternating magnetic field. Specifically, after the heating body 11 senses the alternating magnetic field, the heating body 11 cuts the alternating magnetic lines to generate the alternating current.
In the present embodiment, the heating body 11 is a ferromagnetic pipe carrying a flowing liquid, and an alternating magnetic field is induced through the ferromagnetic pipe carrying the flowing liquid. The ferromagnetic pipeline can be a part or all of ferromagnetic pipeline, or a section of the ferromagnetic pipeline can be ferromagnetic, or a whole section of the ferromagnetic pipeline can be ferromagnetic.
In some embodiments, the heating body 11 is a ferromagnetic material, which is disposed on an inner sidewall of a pipeline carrying the flowing liquid, and an alternating magnetic field is induced through the pipeline carrying the flowing liquid and having the ferromagnetic material disposed on the inner sidewall thereof. The pipeline induces an alternating magnetic field, and the alternating magnetic field is substantially induced by ferromagnetic objects on the inner side wall of the pipeline. In this embodiment, the ferromagnetic material is a ferromagnetic sheet material, and the ferromagnetic sheet material is attached to the inner side wall of the pipeline.
The heating body 11 generates heat energy by itself according to the alternating current. Specifically, after the heating body generates the alternating current, the current carrier of the heating body 11 moves randomly at a high speed, and the current carrier collides and rubs with atoms to generate heat energy. Since the heating body 11 is self-heating, the heat conversion rate is high.
The heating body 11 directly heats the flowing liquid flowing therethrough according to thermal energy. Specifically, the heating body 11 itself generates heat and directly heats the flowing liquid flowing through itself, and since the heating body 11 itself generates heat, the heating body 11 is in direct contact with the flowing liquid, so that the heat transfer efficiency of the heating body 11 is high.
The system also comprises a second detection module for detecting whether the flowing liquid is in a flowing state; if the second detection module detects that the flowing liquid is in a flowing state, the electromagnetic induction coil 12 starts to generate an alternating magnetic field. In the present embodiment, when the flowing liquid is in a flowing state, the electromagnetic induction coil 12 starts to generate an alternating magnetic field, automatically generates the alternating magnetic field, and further heats the flowing liquid.
Whether the flowing liquid is in a flowing state is detected, in this embodiment, whether the flowing liquid is in the flowing state is detected within a preset time, and the preset time is 2 s. The second detection module is a pressure sensor, and the pressure sensor is used for detecting whether the flowing liquid is in a flowing state or not, wherein the pressure generated by the flowing liquid in the flowing state is larger than the pressure generated by the flowing liquid in the static state. When the flowing liquid is detected to be in a flowing state, the electromagnetic induction coil 12 is energized to generate an alternating magnetic field in the electromagnetic induction coil 12. If the flowing liquid is detected to be in a static state, the electromagnetic induction coil 12 is powered off, so that the electromagnetic induction coil 12 does not work, and an alternating magnetic field cannot be generated.
The system further comprises:
a first detection module for detecting the flow rate of the flowing liquid flowing through the heating body 11;
and the first regulating and controlling module is used for regulating and controlling the intensity of the alternating magnetic field generated by the electromagnetic induction coil 12 according to the flow velocity.
After the heating body 11 generates heat energy to heat the flowing liquid, the flowing liquid is detected, the flow speed of the flowing liquid is detected, and the intensity of the alternating magnetic field is regulated and controlled according to the flow speed.
When the flow rate of the flowing liquid is detected to be larger than a preset threshold value, the alternating magnetic field intensity is increased, when the flow rate of the flowing liquid is detected to be equal to the preset threshold value, the current alternating magnetic field intensity is not changed, and when the flow rate of the flowing liquid is detected to be smaller than the preset threshold value, the alternating magnetic field intensity is reduced.
In this embodiment, the electromagnetic induction coils 12 are multiple sets, and the first control module controls one or more sets of electromagnetic induction coils in the multiple sets of electromagnetic induction coils 12 to be turned on according to the flow velocity, so as to increase or decrease the intensity of the alternating magnetic field. A plurality of sets of electromagnetic induction coils 12 are provided, one or more sets of which are switched on as required for increasing or decreasing the intensity of the alternating magnetic field.
If the mass of the object composed of the ferromagnetic material is small enough, the object is in direct contact with the flowing liquid, so that when the object composed of the ferromagnetic material heats the flowing liquid, the temperature difference between the object composed of the ferromagnetic material and the flowing liquid is small, the specific heat of the object composed of the ferromagnetic material is small, and the mass of the object composed of the ferromagnetic material is light, so that in the heating process of the object composed of the ferromagnetic material, if the heating is stopped, more heat is not continuously conducted to the flowing liquid, and the temperature of the flowing liquid is increased. When an object made of ferromagnetic materials stops self-heating, the flowing liquid almost immediately changes to a non-heating state, the flowing liquid which lasts for a period of time can not continuously receive the heat remained by the heating device, and the problem that the flowing liquid can be heated for a period of time after the heating of the existing resistance heater is stopped is solved.
In conclusion, the alternating magnetic field is induced by the heating body to generate the alternating current, the alternating current enables the heating body to generate heat energy, the generated heat energy is used for directly heating flowing liquid flowing through, the flowing liquid can be indirectly heated without heating an isolating device and an insulating device, and the problem that the heat transfer efficiency of the existing resistance-type heater is low is solved.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
