Abstract
The utility model discloses a kind of waste heat recovery air stove, including, furnace shell, combustor, regenerator, vault, cold air inlet, hot-blast outlet, aerator, air collecting box and recovery channel.Releasing the heat stage in air stove air-supply, air collecting box can be by heat unnecessary in stove and dirt absorption, and recovered pipeline and aerator blast and come back to regenerator, recycles used heat, improves air stove work efficiency, and dust in absorption furnace, improves workshop condition simultaneously.
Description
Technical field
This utility model relates to firing equipment technical field, particularly relates to a kind of air stove.
Background technology
Air stove head temperature, the temperature of 40 to 50 degrees Celsius, belongs to thermal loss.The irregular furnace lifting of air stove,
, there is the phenomenon of local leakage ash, on the one hand affect workshop condition, the opposing party's fever sensation of the face in pressure stove process, it may appear that phenomenon of expanding with heat and contract with cold
Wind furnace top not resistance to compression, therefore top dust stratification needs periodic cleaning.
Utility model content
This utility model provides a kind of waste heat recovery air stove, it is possible to absorbs unnecessary used heat, clears up ashes simultaneously.
For reaching above-mentioned purpose, embodiments of the invention adopt the following technical scheme that
A kind of waste heat recovery air stove, including: furnace shell, combustor, regenerator, vault, cold air inlet, hot-blast outlet, drum
Blower fan, air collecting box and recovery channel.Described combustor and regenerator are arranged side by side, and are respectively mounted described hot-blast outlet and described
Cold air inlet, furnace shell described in outer housing, vault described in top cover, described vault installs described air collecting box and also connects described recovery channel,
Guide described cold air inlet, before described cold air inlet, aerator is set.
Wherein, the heat storage in described regenerator is lattice brick.
Wherein, described recovery channel end arranges electric butterfly valve, controls air quantity.
Air stove uses periodic working system, burning releasing two stages of heat that store heat and blow complete.
Burning stores heat the stage, and in order to air stove burn-out, cold air inlet and hot-blast outlet be closed, coal gas and air are pressed
Certain ratio sends into combustion chambers burn, when air stove is heated to the temperature needed, enters air-supply and releases the heat stage.
The heat stage is released in air-supply, and cold air inlet and hot-blast outlet are opened, and the aerator of cold air inlet front end blasts cold wind
Blast furnace is sent into after heating.Now air collecting box work, the used heat can not being utilized in absorbing air stove and in-furnace dust dirt, collection
The recovered pipeline of used heat imports cold air inlet, and recovery channel arranges electronic dish valve, and shell controls air quantity, aerator be mixed into cold wind
Together blasting regenerator, cold wind is heated when by lattice brick, and hot blast is derived through hot-blast outlet.Air-supply a period of time, air stove
The heat stored reduces, it is impossible to by cold air heating to required temperature, the most just by the most again proceeding to burning storage heat
The amount stage.
The beneficial effects of the utility model are yes: described waste heat recovery air stove can recycle used heat, improve air stove
Work efficiency, dust in absorption furnace, improves workshop condition simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Wherein: furnace shell-1, combustor-2, regenerator-3, vault-4, cold air inlet-5, hot-blast outlet-6, aerator-7,
Air collecting box-8, recovery channel-9, lattice brick-10, electric butterfly valve-11.
Detailed description of the invention
For making those skilled in the art be more fully understood that technical scheme, below in conjunction with the accompanying drawings and specific embodiment party
The present invention is described in further detail by formula.
As it is shown in figure 1, a kind of waste heat recovery air stove, including, furnace shell 1, combustor 2, regenerator 3, vault 4, cold wind enters
Mouth 5, hot-blast outlet 6, aerator 7, air collecting box 8 and recovery channel 9.Combustor 2 and regenerator 3 are arranged side by side, and are respectively mounted
Furnace shell 1 described in hot-blast outlet 6 and cold air inlet 5, combustor 2 and regenerator 3 outer housing, vault 4 described in top cover, described vault 4 is pacified
Dress air collecting box 8 also connects recovery channel 9, guides described cold air inlet 5, and recovery channel 9 end arranges electric butterfly valve 11, is used for controlling
Air quantity processed, cold air inlet 5 front end arranges aerator 7, is used for blasting cold wind.
Wherein, the heat storage in regenerator 3 is lattice brick 10.
Air stove uses periodic working system, burning releasing two stages of heat that store heat and blow complete.
Burning stores heat the stage, in order to air stove burn-out, cold air inlet 5 and hot-blast outlet 6 are closed, and coal gas and air
Send into combustor 2 according to a certain percentage to burn, when air stove is heated to the temperature needed, enters air-supply and release the heat stage.
The heat stage is released in air-supply, and cold air inlet 5 and hot-blast outlet 6 are opened, and the aerator 7 of cold air inlet 5 front end blasts
Blast furnace is sent into after cold air heating.Now air collecting box 8 works, the used heat can not being utilized in absorbing air stove and in-furnace dust dirt,
The recovered pipeline of used heat 9 collected imports cold air inlet 5, recovery channel 9 arranges electronic dish valve 11, is used for controlling air quantity, useless
Heat is mixed into cold wind by aerator 7 and together blasts regenerator 3, and cold wind is heated when by lattice brick 10, and hot blast is led through hot-blast outlet 6
Go out.Air-supply a period of time, the heat that air stove stores reduces, it is impossible to by cold air heating to required temperature, the most just by sending
The wind phase again proceeds to burning and stores heat the stage.
