Description
Technical Field
The utility model relates to an electric heating unit technical field, in particular to electric heating unit with circulation constant temperature liquid mixing device.
Background
The electric heating unit drives the mixed energy-gathering medium in the closed container through electric energy to generate a large amount of heat, and then the heat is transferred to the tail end of the heating system through a heat exchange system in the unit to achieve the purpose of heating. In actual work, the media that these are heated can take place temperature gradient layering phenomenon because of the action of gravity in the container, and the temperature of upper strata is high the temperature of lower floor is low promptly, and the unit will cause a large amount of calorific loss carrying out the heat exchange process like this to greatly reduced heat transfer effect has reduced the thermal efficiency of unit, influences the heating effect. At present, in order to solve the technical problem, the problem can be solved only by increasing the power of the unit or increasing the working time of the unit, but the heating operation cost is increased.
Disclosure of Invention
In order to solve the problems of the prior art, the utility model provides an electric heating unit with a constant temperature liquid mixing device, which has simple structure and can improve the heat efficiency of the unit.
The technical scheme of the utility model as follows:
the utility model provides an electric heating unit with circulation constant temperature mixes liquid device, is including preheating recovery water jacket, the airtight storehouse of medium in be equipped with hindering nature electric heating rod, one side of the airtight storehouse of medium be equipped with dividing wall type heat exchange tube, the opposite side of the airtight storehouse of medium be equipped with and preheat recovery water jacket, the airtight storehouse of medium in bottom low temperature medium draw out from the liquid outlet department and get back to in the airtight storehouse of medium through returning the liquid mouth, the airtight storehouse of medium pass through pipe connection oil-gas separation jar, the pipeline between airtight storehouse of medium and the oil-gas separation jar on be equipped with 0.15 Mpa's explosion-proof valve.
The utility model provides a beneficial effect that technical scheme brought is:
through install high temperature resistant medium circulating pump additional on the unit, make the medium in the medium storehouse let upper and lower floor's intensive mixing under the forced circulation of high temperature resistant medium circulating pump in heating process to reach upper and lower floor's temperature and be close unanimous, solve medium temperature gradient phenomenon, improved heat transfer effect greatly, reduced calorific loss, improved the thermal efficiency of unit, thereby realized reaching under the prerequisite of same heating effect, practiced thrift the energy-conserving effect of 30% -50% running cost than traditional electricity heating unit. The explosion-proof valve of 0.15Mpa is additionally arranged, when the pressure in the unit exceeds the set pressure, the high-temperature gas-liquid mixture in the unit breaks through the explosion-proof valve and enters the oil-gas separation cylinder to discharge high-temperature high-pressure gas, and the unit still keeps closed operation to play a role of safety protection.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, an electric heating unit with a circulating constant-temperature liquid mixing device comprises a preheating recovery water jacket 1 and a medium closed bin 2, wherein a resistive electric heating rod is arranged in the medium closed bin 2, a dividing wall type heat exchange tube 3 is arranged on one side of the medium closed bin 2, the preheating recovery water jacket 1 is arranged on the other side of the medium closed bin 2, a low-temperature medium at the bottom in the medium closed bin 2 is pumped out from a liquid outlet by a high-temperature resistant circulating pump 5 and returns to the medium closed bin 2 through a liquid return port, the medium closed bin 2 is connected with an oil-gas separation cylinder 6 through a pipeline, and an explosion-proof valve 4 of 0.15Mpa is arranged on the pipeline between the medium closed bin 2 and the oil-gas separation cylinder 6.
When the electric heating unit normally works, the low-temperature medium at the bottom in the medium closed bin 2 is pumped out from the liquid outlet by the high-temperature-resistant circulating pump 5 and returns to the medium closed bin 2 through the return liquid, so that the temperatures of the upper layer and the lower layer of the medium in the medium closed bin 2 tend to be consistent through the reciprocating circulation, the heat exchange efficiency of the unit is improved, and the purpose of energy-saving heating is achieved.
A pressure relief opening is led out from the top end of the unit, a 0.15Mpa explosion-proof valve 4 is additionally arranged in the middle of the unit, when the pressure in the unit exceeds a set pressure, a high-temperature gas-liquid mixture in the unit breaks through the explosion-proof valve 4 and enters an oil-gas separation cylinder 6 to discharge high-temperature and high-pressure gas, and the unit still keeps closed operation to play a role in safety protection.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
