Description of drawings
The structure principle chart of the device that Fig. 1 provides for the utility model embodiment.
The specific embodiment
In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of solid-fuelled typed high temperature air burning device; It is characterized in that; Comprise: body of heater 101, be arranged on first regenerator 102 and second regenerator 103 on the body of heater 101, in other embodiments, also more regenerator can be arranged.Wherein: a side of each regenerator is provided with air nozzle; Each regenerator all is communicated with body of heater 101 inner spaces through air nozzle in a side; Each regenerator all connects air blast and air-introduced machine at opposite side via reversal valve 109; In the figure of present embodiment, said first regenerator 102 is connected shared air blast 110 and air-introduced machine 111 with second regenerator 103 via shared reversal valve 109.In other embodiment, each regenerator also can be connected to air blast and air-introduced machine separately via reversal valve separately.
In the present embodiment; This device also comprises at least one fuel nozzle 104 that is arranged on the body of heater 101; More nozzle can be arranged; This fuel nozzle 104 also connects pneumatics wind and connects gas pipeline and solid fuel pipeline, and its solid fuel is to be brought into to form in the stove by compressed air or the combustion air that is higher than 15kp through pipeline to burn.
This fuel nozzle 104 links to each other with fuels sources so that to body of heater 101 inner space fuel supplying, and wherein, the air nozzle of this fuel nozzle 104 and first regenerator 102 and second regenerator 103 is independently of one another.
All be provided with heat storage in each said regenerator; Store the entrained heat of this flue gas when receiving the body of heater institute discharged flue gas of kiln, and utilize its this combustion air of stored heat (heat accumulation of heat storage and heat release are according to the needs setting of time and exhaust gas temperature) during to body of heater inner space supply combustion air when this regenerator with this regenerator of box lunch.
In the above-described embodiments; Preferred; Be provided with thermocouple on the pipeline between said body of heater 101, each regenerator (as: first regenerator 102 and second regenerator 103), fuel nozzle 104, each regenerator and the reversal valve; Promptly comprise: first thermocouple 105, second thermocouple 106, three thermocouple 107, the 4th thermocouple 108 and the 5th thermocouple 113, said thermocouple all is connected on the switch board 112, and said switch board 112 also connects air-introduced machine 111 and air blast 110 respectively.Said switch board is used for controlling said air blast 110 and air-introduced machine 111.Air blast 110 connects Flue valve.
When work, fuel nozzle provides fuel to burn to the body of heater inner space constantly.Fuel can be liquid fuel or gaseous fuel and solid fuel mixed combustion, also can distinguish independent burning.First regenerator in said at least two regenerator is communicated with air blast via reversal valve; So that to this body of heater inner space combustion air is provided through its air nozzle; Wherein, This combustion air can be heated to higher temperature (for example lower slightly than the temperature in body of heater inner space temperature) through the heat storage in this first regenerator the time, so that improve the efficient of fuel in the burning of body of heater inner space; Simultaneously; Second regenerator in said at least two regenerator then is communicated with air-introduced machine via reversal valve; So that attract from the flue gas of this kiln discharge; And through entrained heat in this flue gas of the storage of the heat storage in this second regenerator, to be used for heating combustion air (exhaust gas temperature in these two regenerator has thermocouple to detect) subsequently.Through after the time of setting (controlling) by PLC [Programmable Logic Controller]; Through changing the orientation of each reversal valve; First regenerator is communicated with so that attract the kiln discharged flue gas and store the energy in this flue gas with air-introduced machine; And second regenerator is communicated with air blast so that in kiln, supply combustion air (this switching is switched through the ecp of switch board, according to the exhaust gas temperature control of regenerator).The supply of combustion air is so back and forth carried out, and fuel then passes through burner noz(zle) constantly in the kiln internal combustion.
More than a kind of solid-fuelled typed high temperature air burning device that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
