Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.
What need explanation in advance is that all kinds of fluidic flow directions when the arrow among Fig. 1 is represented the utility model operation will detail below no longer one by one.
Technical process when Fig. 1 shows schematic structure and the utility model operation of the utility model; Shown in it; The utility model discloses water glass kiln low parameter waste heat boiler, and body of heater has chimney intake 17, flue outlet 7, main road flue 13 and bypass flue 15.
Body of heater is installed drum 2 and deoxygenator 5 outward.
Wherein, suphtr 11, vaporizer 3, economizer 4, to remove oxygen evaporator 9, drum 2 and deoxygenator 5 all be existing installation.Suphtr 11 is the heating surfaces that in the boiler saturated vapor under the certain pressure are heated into the superheated vapour under the relevant pressure.Vaporizer 3 is the equipment that the fractional saturation water that derives from drum is heated into wet saturated steam.Economizer 4 is exactly in the boiler back end ductwork oiler feed to be heated to certain temperature, has reduced the funnel temperature of flue gas, has saved the energy, has improved efficient.Drum 2 (also claiming drum) is a most important pressure parts in the natural circulation boiler, and saturation water is accomplished in this equipment with dry saturated vapour and separated.Deoxygenator 5 is in the boiler feed water system, makes feedwater be heated to temperature of saturation, can remove the contact(-type) heater of gas dissolved in the feedwater.Removing oxygen evaporator 15 (as: product of Hangzhou Boiler Factory, the bright industry boiler in Huzhou ltd) is the equipment that the feedwater of boiler is heated to temperature of saturation under the corresponding pressure, thus realize oxygen in deoxygenator with the purpose of water sepn.
The water at low temperature inlet of deoxygenator 5 is connected with extraneous water-supply pipe through pipe L1; The internal recycle water out of deoxygenator 5 is connected with the inlet that removes oxygen evaporator 9 through pipe L2; The outlet that removes oxygen evaporator 9 is connected with the internal recycle inlet of deoxygenator 5 through pipe L3; The high-temperature water outlet of deoxygenator 5 is connected with the inlet of service pump 20 with economizer 4 through pipe L4; The outlet of economizer 4 is connected with the inlet of drum 2 through pipe L5, and the internal recycle water out of drum 2 is connected with the inlet of vaporizer 3 through pipe L6, and the steam water interface outlet of vaporizer 3 is connected with the internal recycle inlet of drum 2 through pipe L7; The dry saturated vapour outlet of drum 2 is connected with the inlet of suphtr 11 through pipe L8, and the high-temperature steam outlet of suphtr 11 is led to outside the body of heater through pipe L9.
In order to fully utilize the energy better; Waste heat boiler has also been set up unit (not drawing among the figure); Tensimeter 1 then has been installed on the water glass kiln; Unit is connected with tensimeter 1, main road inlet baffle 14, main road outlet damper 8 and by-pass damper 16, and unit is according to the opening degree of pressure signal control main road inlet baffle 14, main road outlet damper 8 and the by-pass damper 16 of tensimeter 1.
When the utility model was worked under the condition of the normal operation of waste heat boiler, the high-temperature flue gas that water glass kiln 19 produces got into chimney intake 17 after regenerator or interchanger 18 completion heat exchange, get into waste heat boiler through main road flue 13.Hot flue gas in waste heat boiler to suphtr 11, vaporizer 12, economizer 4 with remove oxygen evaporator 9 heat releases; Realize heat exchange with above-mentioned heating surface; Flue-gas temperature reduces, and the flowed through working medium of waste heat boiler of the waste heat of flue gas absorbs, and realizes the UTILIZATION OF VESIDUAL HEAT IN of flue gas; Cooled smoke gets into induced draft fan 6 through the flue outlet 7 of waste heat boiler, finally enters atmosphere.The low parameter steam that the utility model produces: pressure range 0.8MPa～2.5MPa, 170 ℃～400 ℃ of TRs.
The cold water path that heat exchange is used is: and deoxygenator 5 (such as: it is the deoxygenator of 0.35 MPa (a) that the bright industry boiler vessel in Huzhou Manufacturing Co., Ltd produces pressure) be an airtight container; According to Henry's law; When the water in the deoxygenator 5 is heated to the temperature of saturation under the relevant pressure; Can make most of oxygen of being dissolved in the water and separate and discharge from the opening of deoxygenator 5, realize the purpose of deoxygenation, the oxygen in the anti-sealing is to the corrosion of follow-up pipeline, container.The utility model is that deoxygenator 5 is directly squeezed in the chemically treated feedwater of process, deoxygenator 5 with remove oxygen evaporator 9 and be connected, the inner water of deoxygenator 5 are through removing oxygen evaporator 9 heating back formation saturation waters, and the purpose of realization deoxygenation.The deaerated water pressurization back of leaving deoxygenator 5 gets into economizer 4, and the heating back gets into drum 2, and the water that drum is 2 li generates saturation steam after vaporizer 3 heating, and the saturation steam that leaves drum 2 forms superheated vapour and leaves waste heat boiler after suphtr 11 heating.
When waste heat boiler was in shut down condition, main road inlet baffle 14 was closed with main road outlet damper 8, and by-pass damper 16 is opened, and the hot flue gas that derives from regenerator or interchanger 18 directly gets into induced draft fan 6 and enters atmosphere through bypass flue 15.Coming into operation of bypass flue 15 and by-pass damper 16 under the waste heat boiler fault condition, can guarantee water glass kiln ordinary production.
In sum, the utility model can efficiently utilize the fume afterheat that leaves regenerator or interchanger 18 through on the flue outlet of regenerator or interchanger 18, the low parameter waste heat boiler being set.Through bypass flue 15 is set, under the waste heat boiler fault condition, can guarantee water glass kiln ordinary production, effectively prolong the continous-stable cycle of operation of water glass kiln.
Can know that by technological general knowledge the utility model can be realized through other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the utility model all comprised by the utility model.
