Description
Technical field
The present invention relates to boiler, relate in particular to a kind of chemical emission boiler furnace that uses.
Background technology
Along with the Chinese national economy sustainable development, energy supply and environmental protection face more and more severeer situation, and energy-saving and emission-reduction have become one of governments at all levels and department's central task.Chlorine industry is China's basic raw material industry, and its product yield and economic indicator are the important indicators of Chinese national economy statistics and examination always.Yet chlor-alkali industry is again energy resource consumption and the larger chemical industry of three wastes discharge amount, and energy-saving and emission-reduction and environment protection treating present situation also allow of no optimist.
Production of chlor-alkali chemical industry enterprise can produce a large amount of byproducts in process of production, its Main Ingredients and Appearance is hydrogen, because the restriction of the factors such as the market price, recovery and utilization technology and cost, be rarely used in the production downstream product, but directly sky is discharged as chemical emission, not only waste energy, again contaminated environment.Hydrogen is a kind of high-quality clean fuel, and the low heat value of the pure hydrogen of 1Nm3 is 2550Kcl, and the smoke components of output mainly is water vapour and nitrogen after 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 capturing the high-risk waste gas recycling of chlor-alkali industry and making hydrogen be used for boiler plant just becomes key point, and rational boiler furnace design concerns efficient and the safety of combustion of hydrogen.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of boiler furnace that uses chemical emission is provided.
For achieving the above object, the technical solution used in the present invention is:
Use the chemical emission boiler furnace and comprise chimney, oblique shutter, cross wind-distributing pipe, burner, steam trap connection, combustion chamber, flue, the first blower fan, the second blower fan; The boiler furnace body is N-type, burner is positioned at the bottom of boiler furnace body N-type one end, the top of boiler furnace body N-type one end is provided with the combustion chamber, the upper end, combustion chamber links to each other with flue, pot is provided with the cross wind-distributing pipe in the middle of the combustion chamber, downward equally distributed some wind distributing holes on the cross wind-distributing pipe, the end of cross wind-distributing pipe links to each other with the second blower fan with the first blower fan respectively, flue and the corresponding section, combustion chamber of boiler furnace body N-type the second bend are provided with oblique shutter, tiltedly be provided with steam trap connection outside the shutter lower bottom part, the upper end of the boiler furnace body N-type other end is provided with chimney.
Compared with prior art, the beneficial effect that has of the present invention is:
1. boiler furnace of the present invention is provided with the cross wind-distributing pipe, the above's some apertures that evenly distributed, and aperture is cross distribution, can greatly increase disturbance, so that hydrogen and air fully mix;
Cross wind-distributing pipe of the present invention the end be provided with blower fan, can control air quantity by control valve, under wind action, hydrogen and air mix more even, thereby control combustion;
3. boiler furnace of the present invention is provided with oblique shutter, thereby has greatly increased the flue gas disturbance, and effectively removes the combustion product steam of hydrogen, and is provided with steam trap connection, collects water droplet, thereby has increased combustion thermal efficiency.
4. structure of boiler body adopts vertical, and size of burner hearth and shape are optimized the technological innovations such as coupling with combustion hydrogen flame shape, can prevent that residual hydrogen from gathering the generation of ignition and tempering phenomenon, guarantees safety, the reliability service of device.
Description of drawings
Fig. 1 is the boiler furnace structural representation that uses chemical emission;
Fig. 2 is the top view of A-A face of the present invention;
Among the figure: chimney, oblique shutter 2, cross wind-distributing pipe 3, burner 4, steam trap connection 5, combustion chamber 6, flue 7, the first blower fan 8, the second blower fan 9.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and example.
As shown in Figure 1, use the chemical emission boiler furnace and comprise chimney, oblique shutter 2, cross wind-distributing pipe 3, burner 4, steam trap connection 5, combustion chamber 6, flue 7, the first blower fan 8, the second blower fan 9; The boiler furnace body is N-type, burner 4 is positioned at the bottom of boiler furnace body N-type one end, the top of boiler furnace body N-type one end is provided with combustion chamber 6,6 upper ends, combustion chamber link to each other with flue 7, be provided with cross wind-distributing pipe 3 in the middle of the pot combustion chamber 6, downward equally distributed some wind distributing holes on the cross wind-distributing pipe 3, the end of cross wind-distributing pipe 3 links to each other with the second blower fan 9 with the first blower fan 8 respectively, flue 7 and 6 corresponding sections, combustion chamber of boiler furnace body N-type the second bend are provided with oblique shutter 2, tiltedly be provided with steam trap connection 5 outside shutter 2 lower bottom parts, the upper end of the boiler furnace body N-type other end is provided with chimney.
The course of work of the present invention is as follows:
Hydrogen is lighted through burner 4, mix with air, and in the combustion chamber 6 internal combustion, hydrogen and air gas mixture have always increased disturbance through the aperture of cross wind-distributing pipe 3, link to each other with the second blower fan 9 with the first blower fan 8 respectively in the end of cross wind-distributing pipe 3, can control air quantity by control valve, under the effect of blower fan, can be so that hydrogen and air fully mix, and can control combustion.Flue gas enters flue 7 subsequently, by oblique shutter 2, thereby has greatly increased the flue gas disturbance.Because the product of combustion of hydrogen mainly is steam and nitrogen, therefore, during the oblique shutter 2 of flue gas process, the surface that steam can be attached to oblique shutter 2 becomes water droplet, and water droplet then can splash in the steam trap connection 5 of below, thereby has improved the thermal efficiency.At last, flue gas enters atmosphere through chimney.
