Description
Technical field
The present invention relates to boiler technology fields, and in particular to a kind of electric boiler.
Background technique
Boiler is thermal energy supply equipment important in national economy.Electric power, machinery, metallurgy, chemical industry, weaving, papermaking, food
Etc. industries, and industry and civil heating require boiler and supply a large amount of thermal energy.Boiler currently on the market uses water mostly
As heat medium, and in boiler During Process of Long-term Operation, the easy fouling of water is attached on boiler wall, and scale can seriously affect biography first
Heat causes the waste of energy, and after boiler fouling, and the heat of fuel combustion cannot be transmitted to water side in time, makes heating surface temperature
Degree increases, if boiler heating surface is run under overtemperature state for a long time, creep, bulge will occur for metal material, and intensity decline has quick-fried
The danger of pipe, in addition, can cause boiler underdeposit corrosion after fouling, boiler corrosion will shorten its service life, jeopardize safe operation,
Cause economic loss.
Summary of the invention
To solve the problems, such as proposed in background technique, the present invention provides a kind of electric boilers.
To achieve the above object, the present invention provides the following technical solutions.
Including air heater, hydro-thermal heat exchanger, blower, valve, pipeline and muff.In the air heater inner cavity
Equipped with multiple baffle plates, the heater element of the air heater is stainless steel electric heating tube, in the stainless steel electric heating tube
To be equipped with control panel on the air heater, being provided with heat exchange plate in the hydro-thermal heat exchanger cavity equipped with resistance wire
Pipe, the air heater, hydro-thermal heat exchanger are connected with blower by pipeline, are formed into a loop, and the muff is common heat preservation
Cotton, external form are matched with pipeline.
Baffle plate in the air heater inner cavity is equipped with venthole and extends gas in the residence time of inner cavity, improves
Heat exchanger effectiveness.
Resistance wire in the stainless steel electric heating tube is set as S type, increases heating surface (area) (HS.
The control panel is electrically connected with resistance wire, can set heating and cooling process, controls the heating and drop of resistance wire
Warm process.
Lower wall is equipped with water outlet and water inlet, hot-air and cold water reverse heat-exchange on the hydro-thermal heat exchanger.
The valve includes air valve, inlet valve and outlet valve.
The pipeline uses heat-resisting material.
Compared with prior art, the invention has the benefit that being heated using resistance wire to air, the heat after heating
Air enters in hydro-thermal heat exchanger under the action of blower to exchange heat with the cold water in coil pipe, and then realizes the heating to cold water, whole
Heating element does not contact directly with water in a system, but the mistake of water heating is realized by hot-air and water contact heat-exchanging
Journey, air as a heat transfer medium, avoid the phenomenon that water fouling is used for a long time in boiler, while blower acts on the conveying of hot-air
Coil pipe in heat-exchange system can be made to be heated evenly, avoid the danger that booster occurs for local long-term overheat, air follows in whole system
Ring uses, and can efficiently use air waste heat, energy saving, structure is simple, safety and environmental protection, and can realize automation.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention, and Fig. 2 is resistance wire schematic diagram.
In figure: air heater (1), hydro-thermal heat exchanger (2), blower (3), valve (4), pipeline (5), muff (6), folding
Flowing plate (7), stainless steel electric heating tube (8), resistance wire (9), control panel (10), heat exchange coil (11).
Specific embodiment
It is described in detail with reference to the accompanying drawing with case study on implementation.
As shown in Figure 1, the electric boiler, including air heater (1), hydro-thermal heat exchanger (2), blower (3), valve (4), pipe
Road (5) and muff (6).Multiple baffle plates (7) are equipped in air heater (1) inner cavity, baffle plate (7) is equipped with multiple
Venthole guides gas flow, extends gas in the residence time of inner cavity, so that gas be made sufficiently to heat, keeps gas heating equal
It is even, improve heat exchanger effectiveness.The heater element of the air heater (1) is stainless steel electric heating tube (8), the stainless steel electricity
For equipped with resistance wire (9), to increase heating surface (area) (HS, resistance wire (9) is arranged to S shape, the air heater in heating tube (8)
(1) it is equipped with control panel (10), control panel (10) powers on after being electrically connected with resistance wire (9), in control panel (10)
Upper setting heating and cooling process, control heating and the temperature-fall period of resistance wire, entire air heating plant can by air stream from
Initial temperature is heated to required temperature, and maximum temperature is up to 850 DEG C, and case temperature only has 50 DEG C or so, securely and reliably, can be real
Now automate.
It is provided with heat exchange coil (11) in hydro-thermal heat exchanger (2) inner cavity, increases heat exchange area, to further increase heat exchange effect
Rate, using countercurrent heat exchange method, water inlet is arranged on the right side of equipment lower wall, and water outlet is in upper wall leftward position.Air heater
