Description
Technical field
The utility model relates to a kind of boiler, refers to a kind of chemical emission boiler furnace structure especially.
Background technology
Production of chlor-alkali chemical industry enterprise can produce a large amount of byproduct in process of production, its Main Ingredients and Appearance is hydrogen, due to the restriction of the factors such as the market price, recovery and utilization technology and cost, be rarely used in production downstream product, but directly sky is discharged as chemical emission, not only waste energy, again contaminated environment.Hydrogen is a kind of clean fuel of high-quality, and the low heat value of the pure hydrogen of 1Nm3 is 2550Kcl, and smoke components mainly water vapour and the nitrogen of the rear output of its burning; Hydrogen is again a kind of high-risk explosive fuel gas simultaneously, and its explosion limit is the widest in all fuel gas, very easily produces blast.Therefore, how to capture the high-risk waste gas recovery of chlor-alkali industry and utilize and make hydrogen just become key point for boiler plant, and reasonably boiler furnace design concerns efficiency and the safety of combustion of hydrogen.
Utility model patent " using chemical emission boiler furnace " (patent No.: ZL201310040293.1), although its technical scheme overcomes above-described problem, also there is hydrogen and the problem such as air mixed effect is not good, steam clearance is low, combustion thermal efficiency is low, complex structure, occupation area of equipment are large in its technical scheme.
Utility model content
Problem to be solved in the utility model is the deficiency overcome in background technology, a kind of chemical emission boiler furnace structure is provided, this chemical emission boiler furnace structure, the problem such as overcome hydrogen and air mixed effect is not good, steam clearance is low, combustion thermal efficiency is low, complex structure, occupation area of equipment are large.
For solving the problem, the utility model takes following technical scheme:
A kind of chemical emission boiler furnace structure of the present utility model, comprise burner hearth body, described burner hearth intrinsic single is H type structure, the below of one end of described burner hearth body is provided with support, the bottom of one end of described burner hearth body is provided with burner, and the top of described burner hearth body is provided with combustion chamber, and the middle part of described combustion chamber is provided with ventilation duct, to being arranged with multiple air vent on described ventilation duct, one end of described ventilation duct is connected with outer fan; The upper end of described combustion chamber is connected with the middle part of flue, the upper and lower of described flue is respectively arranged with the first oblique shutter and the second oblique shutter, the upper outer of the described first oblique shutter is provided with chimney, and the lower bottom part arranged outside of the described second oblique shutter has steam trap connection.
Further, described ventilation duct is that star symmetrical chiasma forms by the first ventilation duct, the second ventilation duct, the 3rd ventilation duct, one end of described first ventilation duct is connected to the first blower fan, one end of described second ventilation duct is connected to the second blower fan, and one end of described 3rd ventilation duct is connected to the 3rd blower fan.
Compared with prior art, the beneficial effect that the utility model has is:
Chemical emission boiler furnace structure of the present utility model, star ventilation duct is set, some apertures are uniformly distributed above, aperture is star distribution, and star distribution crossing distribution compared to existing technology, on same cross section, the air agitation amount of unit are is multiplied, and makes hydrogen and air obtain further fully mixing.
Chemical emission boiler furnace structure of the present utility model, is provided with Double-layer oblique shutter, therefore in limited space, adds the loop of flue gas disturbance, improves the clearance of the combustion product steam of hydrogen further, thus improves combustion thermal efficiency at double.
Chemical emission boiler furnace structure of the present utility model, adopt the vertical of H type structure, the N type junction structure adopted compared to existing technology, simplifies equipment size, reduces occupation area of equipment, thus save equipment and materials, reduce manufacturing cost.It is little that the utility model has equipment volume, low cost of manufacture, advantage easy to install.
