Abstract
The invention relates to a hot gas backflow heating furnace. The hot gas backflow heating furnace comprises a heating furnace cylinder, wherein a combustion chamber is formed in the heating furnace cylinder, a heating element is arranged at the bottom of the combustion chamber, the heating element is arranged at the bottom of the interior of the heating furnace cylinder, the heating element is connected with the combustion chamber through a hot gas transmission port, one end of the hot gas transmission port is connected with an air inlet, the top of the combustion chamber is connected with an air outlet, a diversion cylinder is arranged between the air outlet and the combustion chamber, one side of the diversion cylinder is connected with a hot air backflow pipe, and a hot gas backflow cavity is formed between the inner wall of the heating furnace cylinder and the outer wall of the combustion chamber. Compared with the prior art, the hot gas backflow heating furnace has the following advantages of enabling discharged hot gas to flow back so as to preheating the outer wall of the combustion chamber, preventing loss of heat, causing no waste of resources, and being high in heat use rate.
Description
Technical field
The present invention relates to a kind of hot gas re-flow heating furnace, belong to heating furnace technical field.
Background technology
In metallurgical industry, heating furnace is to being rolled into setting of forging temperature by material or workpiece
Standby.Heating furnace application throughout oil, chemical industry, metallurgy, machinery, heat treatment, surface process,
Many industry fields such as building materials, electronics, material, light industry, daily use chemicals, pharmacy.Heating furnace,
Various industrial furnaces, boiler are all highly energy-consuming kilns, and resource cost amount is big.Heating furnace is to steel ingot
Temperature when heating is high, and flue gas has been taken away substantial amounts of heat of high temperature, caused and waste,
Heat utilization efficiency is relatively low.
Therefore, it should provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The present invention provides a kind of hot gas re-flow heating furnace.
For reaching above-mentioned purpose, the technical solution used in the present invention is:
A kind of hot gas re-flow heating furnace, including heating furnace cylinder, heating furnace inner barrel is provided with
Burning cavity, burning cavity bottom is provided with heating element heater, and heating element heater is located at heating furnace cylinder
Interior bottom portion, is connected by steam transmission mouth between heating element heater and burning cavity, and steam passes
Outlet one end connects air intake, and burning cavity top connects air outlet, air outlet and burning
Being provided with stream guiding barrel between cavity, stream guiding barrel side connects hot air reflux pipe, heats furnace tube
Hot gas re-flow chamber is formed between internal wall and burning chamber outer wall.
The relevant content of technique scheme is explained as follows:
In technique scheme, hot gas re-flow chamber roof is provided with backflow air outlet, refluxes out
Heating furnace cylinder top is located in air port.
Further technical scheme, burning chamber outer wall is provided with refractory insulating layer.
Preferably, hot air reflux pipe top connects stream guiding barrel, is located at bottom hot air reflux pipe
Hot gas re-flow cavity bottom.
Owing to technique scheme is used, the present invention compared with prior art has following excellent
Point:
The hot gas re-flow that will discharge, to burning chamber outer wall preheating, prevents the loss of heat,
Not wasting resource, heat utilization efficiency is high.

11, prevent from burning the loss of heat in cavity 2, is provided with heating element heater 3 bottom burning cavity 2,
Heating element heater 3 is located at heating furnace cylinder 1 interior bottom portion, heating element heater 3 and burning cavity 2
Between by steam transmission mouth 4 connect, steam transmission mouth 4 one end connect air intake 5, add
The circulation of fast steam, burning cavity 2 top connects air outlet 6, air outlet 6 and burning cavity
Being provided with stream guiding barrel 7 between 2, stream guiding barrel 7 internal medicine selects the element of inducing QI as required,
Such as water conservancy diversion rotating shaft (being not drawn in Fig. 1), stream guiding barrel 7 side connects hot air reflux pipe 8,
Hot air reflux pipe 8 top connects stream guiding barrel 7, and the diameter at stream guiding barrel 7 top is less than bottom
Diameter, facilitate the outflow of gas, bottom hot air reflux pipe 8, be located at hot gas re-flow chamber 9
Bottom so that steam provides steam, heating furnace cylinder 1 inwall and burning cavity 2 thoroughly
Forming hot gas re-flow chamber 9 between outer wall, hot gas re-flow chamber 9 top is provided with backflow air outlet
10, backflow air outlet 10 is located at heating furnace cylinder 1 top, and the hot gas re-flow that will discharge is right
Burning chamber outer wall preheating, prevents the loss of heat, does not waste resource, and heat utilization efficiency is high.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow ripe
The personage knowing technique will appreciate that present disclosure and implements according to this, can not limit with this
Protection scope of the present invention processed.All equivalences made according to spirit of the invention change or repair
Decorations, all should contain within protection scope of the present invention.
