Summary of the invention
The purpose of the utility model provides and a kind ofly can be used for heating HTHP or poisonous flammable reducibility gas, and the efficiency of heating surface is high, heated air temperature gas heating muffle stove even, simple in structure.
The purpose of the utility model realizes through following technical scheme:
The gas heating muffle stove of the utility model comprises body of heater, boiler tube and outer boiler tube in said body of heater comprises; The inner space of boiler tube forms internal furnace in said; Space in said between boiler tube and the outer boiler tube forms outer burner hearth, and said interior boiler tube bottom is a Porous Base, said outer boiler tube bottom seals; Said outer burner hearth is connected with gas inlet tube, and said internal furnace is connected with gas outlet tube;
Said internal furnace and outer burner hearth cut off at the body of heater top each other, and through said Porous Base UNICOM, the placement heater element is also filled the solid conductive heat particle in the said internal furnace at bottom of furnace body.
Technical scheme by above-mentioned the utility model provides can be found out, the gas heating muffle stove that the utility model provides is owing to adopt sleeve type structure; The effect of air cooling layer played in the outer shroud air inlet; Furnace tube material is to the heat resistance requirement in can reducing, and air inlet can play cooling effect to the heating element heater section of drawing, and has guaranteed the effective sealing of the heating element heater section of drawing with outer furnace wall; Make burner hearth possess stronger bearing capacity, can directly produce high temperature and high pressure gas by Muffle furnace; Because the interior boiler tube of employing is filled the solid conductive heat particle and directly contacted with the heater element bringing-up section, is evenly heated when making gas pass through the solid particle slit, the efficiency of heating surface is greatly improved compared to common tubular type gas heating stove.Can be used for heating HTHP or poisonous flammable reducibility gas, and the efficiency of heating surface is high, the heated air temperature is even, and is simple in structure.
Description of drawings
The structural representation of the gas heating muffle stove that Fig. 1 provides for the utility model embodiment.
Among the figure: outer boiler tube 1, interior boiler tube 2, Porous Base 3, heater element 4, spherical ceramic particles 5, top flange 6, gas inlet tube 7, gas outlet tube 8, silicone rubber seal pad 9.
The specific embodiment
To combine accompanying drawing that the utility model embodiment is done to describe in detail further below.
The gas heating muffle stove of the utility model, its preferable specific embodiment is:
Comprise body of heater; Boiler tube and outer boiler tube in said body of heater comprises, the inner space of said interior boiler tube forms internal furnace, and the space between said interior boiler tube and the outer boiler tube forms outer burner hearth; The boiler tube bottom is a Porous Base in said; Said outer boiler tube bottom seals, said outer burner hearth is connected with gas inlet tube, and said internal furnace is connected with gas outlet tube;
Said internal furnace and outer burner hearth cut off at the body of heater top each other, and through said Porous Base UNICOM, the placement heater element is also filled the solid conductive heat particle in the said internal furnace at bottom of furnace body.
The top of said body of heater is provided with top flange, and said gas inlet tube has a plurality of, is symmetrically distributed in the furnace roof periphery, and said gas outlet tube is located at the furnace roof center.
Said heater element comprises bringing-up section and the section of drawing, and said bringing-up section is evenly arranged in the said internal furnace, the said section of drawing pass near the air inlet place said in boiler tube and outside boiler tube, be connected with power supply in the body of heater outside.
Said solid conductive heat uniform particles is filled in the said internal furnace, and directly contacts with the bringing-up section of said heater element.
The gas heating muffle stove of the utility model; Adopt sleeve type structure, the effect of air cooling layer played in the outer shroud air inlet, and outer furnace wall temperature is below 200 ℃ in the time of can realizing that gas is heated to 900 ℃ of high temperature; Furnace tube material is to the heat resistance requirement in can reducing, and outer boiler tube can adopt the common metal material; Because air inlet, has guaranteed the effective sealing of the heating element heater section of drawing with outer furnace wall to the cooling effect of the heating element heater section of drawing, and makes burner hearth possess stronger bearing capacity, can directly produce high temperature and high pressure gas by Muffle furnace; Because the interior boiler tube of employing is filled the solid conductive heat particle and directly contacted with the heater element bringing-up section, is evenly heated when making gas pass through the solid particle slit, the efficiency of heating surface is greatly improved compared to common tubular type gas heating stove.Can be used for heating HTHP or poisonous flammable reducibility gas, and the efficiency of heating surface is high, the heated air temperature is even, and is simple in structure.
