Description
Technical field
The present invention relates to a kind of boiler, more particularly to it is a kind of improve operating efficiency, reduction energy loss, it is generally applicable existing
The greenhouse heating stove of generationization agriculture-stock production.
Background technology
Hot-blast stove is to use air as medium and carrier, and similar warming-up device can be carried larger in the market relatively
A kind of professional warming-up device of high heat utilization efficiency and hot operating efficiency.Pot arch is as thermal power machinery in 1970s
End starts extensive use in China, and it turns into the regeneration product of electric heat source and conventional vapor power heat source in many industries, especially
It is greatly decreased infrastructure device input, lowers production management, processing of agriculture product cost in modernization agriculture-stock production,
Have become irreplaceable warming-up device.Pot arch can be divided into two kinds of heat accumulating type and heat exchange type by operation principle；Wherein accumulation of heat
Formula pot arch, can be with by combustion system by the heat storage bulb separation formula pot arch inside pot arch and using the pot arch of checker brick
It is divided into top ignition, internal combustion type, external-burning etc. is several.The structure of pot arch is combined by combustion furnace and heat exchanger, can be by
The fuel such as fire coal are burnt.The species of current pot arch is various, is applied to every field.The research and development of those skilled in the art
Trend, which is all desirable to pot arch, can be quickly obtained required hot blast, and such as notification number is CN2516889Y, it is possible to realized very
The purpose of the hot blast needed soon, but hot blast in air-out passage by when due to many with heat exchange with outside thermal loss,
Waste is caused, and the distance that wind passes through in passage is short, it is impossible to the heat exchange of pot arch is played completely.CN2516889Y
Because burner hearth side is designed with coal feed point, coal feed point component largely separates in space of the burner hearth between furnace shell, in air rotation
When transhipment is dynamic, the leeward side of coal feed point produces negative pressure formation parital vacuum, and because vacuum area does not have air-flow cooling, burner hearth is easy
Burnt.Also reduce heat exchange efficiency simultaneously.CN2516889Y due to burner hearth structure hot blast outside, including cold wind, stove table temperature
Degree is very high, and stove surface forms very high temperature difference in surrounding air, increases Speed of diffusion, causes energy waste.Applied to existing
, it is necessary to keep more remote with animals and plants when generationization agricultural greenhouse is produced, otherwise causing stove, nearby animals and plants are burnt, and are caused
The underproduction or space waste.CN2516889Y because air inlet is below stove, air outlet in a furnace between, air is moved in stove
Path is short, exchanges heat not thorough, killing effect is reduced to the germ virus in ambient air.
The content of the invention
In order to solve the above-mentioned technical problem the present invention provides a kind of greenhouse heating stove, it is therefore an objective to improves heat exchanger effectiveness, prolongs
Residence time of the long wind in stove, the temperature of discharge hot blast is improved, reduce thermal loss.
Burner hearth is provided with for up to above-mentioned purpose greenhouse heating stove of the present invention, including furnace shell, furnace shell is interior, is between burner hearth and furnace shell
Air intake down going channel, is provided with air intake data feedback channel, air intake down going channel and air intake between burner hearth and air intake down going channel bottom
Row of channels is communicated in bottom, and heat exchanger tube is provided with burner hearth, and air intake data feedback channel top is communicated with heat exchanger tube bottom, heat exchanger tube top
Stretch out roof of the furnace to communicate with air outlet, hollow bar, hollow bar one end and air intake down going channel are provided with the bottom of burner hearth
End communicate, the hollow bar other end is inserted into air intake data feedback channel, burner hearth lower side be provided with coal feed point, enter coal
Mouth stretches out furnace shell, and roof of the furnace is communicated with outlet flue, is separated by air outlet by upper spacer with air intake down going channel, air intake is descending
The air inlet of passage is located at the upper side of furnace shell.
Described air intake down going channel is separated by with air intake data feedback channel by division board.
Described burner hearth inner casing is provided with fin.
Described fin is respectively provided in air intake down going channel and air intake data feedback channel.
Described hollow bar one end is quarter bend.
Described heat exchanger tube first stretches to burner hearth center, then is stretched out to hearth wall direction oblique upper.
It is bottom plate below hollow bar.
The axis of air inlet and furnace shell are tangent.
Advantages of the present invention effect：Cold wind is enclose hot blast by the present invention, prevents hot blast with the cold wind outside furnace shell from carrying out heat
Exchange, make air outlet discharge hot blast be exactly most hot, and the cold wind in air intake down going channel by with burner hearth exchange heat into
Row preheating, improves the temperature into cold wind in heat exchanger tube, improves the thermal efficiency.Because cold wind is entered from above, bottom is moved to
Heat exchanger tube is upwardly into behind portion again, residence time of the cold wind in stove is added, it is ensured that the time of heat exchange.Furnace shell and burner hearth
Between can have cold wind flowing, prevent burner hearth to be locally melted.
