Abstract

The utility model discloses a power boiler, which relates to an improvement on a power boiler structure. The utility model provides the power boiler with good safety, environmental protection, high efficiency of electricity-heat conversion and convenient use. The power boiler comprises a boiler body, and the essential structure is that a far infrared coating, an insulating layer, a heating coil layer, a second-stage insulating layer, a heat insulating layer and a metal shielding cover are sequentially arranged on the surface of the boiler body from inside to outside, and a heat exchanger is arranged in the boiler body; and a water inlet pipe and a water outlet pipe of the heat exchanger are respectively positioned at the top and the bottom of the lateral side of the boiler body.

Description

A kind of electric boiler

Technical field:

The utility model belongs to mechanical engineering, illumination, heating, weapon, explosion portion, illumination, heating branch, heat supply; Cooking stove; The fluid heater group technical field that heat-generating device is generally arranged of ventilation class more particularly, relates to a kind of improvement of electric boiler structure.

Background technology:

Coal-burning boiler is the north a kind of main heating equipment in winter.In order to make fuel completing combustion, reduce the incomplete combustion loss of fuel, the boiler that capacity is big slightly generally all grinds coal become the coal dust also thinner than flour.Coal is made coal dust, and equipment complexity, power consumption are big.And what China adopted when heating is the colm that caloric value is low, ash content is big, so the thermal efficiency is not good.

For preventing coking in the burner hearth, the volume calorific intensity of coal-burning boiler is lower, so combustion space is bigger.Ash content is many in the flue gas, in order to reduce the wearing and tearing of convection heating surface, adopts lower flue gas flow rate, and heat transfer coefficient is lower, so heat transfer area increases.These factors make that the output investment ratio of coal-burning boiler is bigger, and equipment attrition is serious, and maintenance workload is very big.In order to store burning and lime-ash, need take more soil, set up huge coal yard and storage ash field.

Therefore, the coal-burning boiler not only thermal efficiency is low, and can produce large quantity of exhaust gas and waste residue, serious environment pollution in combustion process; In addition, this non-renewable resources of coal combustion also are a kind of great wastes.

The utility model content:

The utility model is exactly at the problems referred to above, provides that a kind of security is good, environmental protection, electric conversion efficiency height, electric boiler easy to use; Be applicable to that fluid radiator does heating system and higher big and medium-sized cities and the acid rain control district of environmental requirement, and the area of electric power resource abundance.

For reaching above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises body of heater, its structural feature is to be disposed with far infrared coating, insulating barrier, heater wire ring layer, secondary insulating barrier, heat-insulation layer, metallic shield from inside to outside on the surface of body of heater, be provided with heat exchanger in body of heater, the water inlet pipe of heat exchanger and outlet pipe lay respectively at the top and the bottom of body of heater side.

Adopt the power electronics boiler of this structure to utilize electromagnetic induction principle and far-infrared technique, electric energy is converted into electromagnetic energy, and electromagnetic energy is transformed into heat energy, stimulates the quick transferring heat energy of heat-conducting medium by far-infrared thermal radiation again, thermal conversion rate reaches more than 97%, heat utilization efficiency 100%; The heat exchanger of individual packages in body of heater can satisfy and wash one's face and rinse one's mouth and hot water for kitchen use, do not provide thermal source and do not influence the medium (water) that flows in the steel pipe for the place that need heat, stable, saving China coal resources few in number easy to use, safe.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

1 is that body of heater, 2 is that far infrared coating, 3 is that insulating barrier, 4 is that heater wire ring layer, 5 is that secondary insulating barrier, 6 is that heat-insulation layer, 7 is that metallic shield, 8 is that heat exchanger, 9 is that water inlet pipe, 10 is an outlet pipe in the accompanying drawing.

The specific embodiment:

The utility model comprises body of heater 1, be disposed with far infrared coating 2, insulating barrier 3, heater wire ring layer 4, secondary insulating barrier 5, heat-insulation layer 6, metallic shield 7 from inside to outside on the surface of body of heater 1, be provided with heat exchanger 8 in body of heater 1, the water inlet pipe 9 of heat exchanger 8 and outlet pipe 10 lay respectively at the top and the bottom of body of heater 1 side.

Described heat exchanger 8 is the metal coil pipe.

During use, by the big current direction heater wire of control high frequency ring layer 4, the strong flux of polarization instantaneous variation in coil, after strong flux connects body of heater 1, direction opposite with heating current in the furnace wall of body of heater 1 just can produce corresponding very big vortex flow, owing to have resistance in the body of heater 1,, the temperature in body of heater 1 furnace wall risen rapidly so can produce a lot of Joule heats.Add that far-infrared radiation is work-assisted, the medium (water) that activates in the body of heater 1 produces covibration, and hydrone absorbs the heat in the stove rapidly, under the effect of external force, conducts heat exchange, and electric conversion efficiency reaches more than 97%.

Be with being appreciated that, more than about specific descriptions of the present utility model, only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
