Abstract
The utility model relates to a vapor smoke-eliminating and dust-removing device for atmospheric boilers, which is characterized in that the root of a chimney of an atmospheric boiler is provided with an annular cavity, the inner wall of the atmospheric boiler is provided with a plurality of spraying holes, and the annular cavity is connected with a pressure-releasing and air-exhausting pipe on the upper part of the boiler through a connection pipe; water vapor discharged into atmosphere by the boiler during operating at ordinary times is led into the annular cavity and then is sprayed through the spraying holes, and then the utility model utilizes the water vapor to clean dust particles in smoke. The utility model can effectively reduce the concentration of the dust particles and other harmful matter in the smoke, has the advantages of simple structure and no energy consumption, and is generally suitable for various atmospheric boilers.
Description
The utility model relates to the washing type dedusting and the desulfurization of normal-pressure boiler, the device of denitrogenation.
At present, the normal pressure boiler for domestic uses very extensive, enormous amount.Though wherein a part has reached the soot emissions index, SO in the discharging flue gas
X, NO
XStill higher etc. content of harmful.Quite a few sulphur, nitrogen compound are contained in the grit and are arranged to atmosphere.In order to remove flue dust, station boiler has so-called washing method, and used process equipment is complicated, and is expensive many, and may cause secondary pollution such as sewage, is unsuitable for general normal-pressure boiler and uses.People know in addition, and water vapour or water smoke can make grit adhere to and aggegation mutually, thereby help sedimentation.Normal-pressure boiler is in use often intermittently discharged a certain amount of waste steam by the top relief tube, and these water vapours had all wasted in the past.
The purpose of this utility model is the device for eliminating smoke and dust that a kind of normal-pressure boiler will be provided, and utilizes the waste steam of this kind boiler emission to reduce the concentration of suspension grit in the flue gas, thereby also reaches the effect of desulfurization, denitrogenation.
Solution of the present utility model is: on the chimney of normal-pressure boiler annular compartment is set, opens some spray holes on the annular compartment inwall, this annular compartment links to each other with the pressure release blast pipe of upper boiler by taking over.
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Fig. 1 is the three-dimensional view of normal-pressure boiler steam dust removing device.
As figure, hollow ring chamber 2 generally is located on the boiler root chimney 1, is positioned at more than the flue air-valve, and flange 7 connects portion's chimney, and flange in the bottom 8 connects stove.Annular compartment 2 is the square-section among the figure, has some spray holes 4 within it on the wall.Have on the annular compartment simultaneously and take over 5 and is communicated with, in the boiler water vapour importing annular compartment that enters atmosphere in service at ordinary times, spray, form a device that utilizes water vapour cleaning dust through spray holes with the pressure release blast pipe of upper boiler.When the boiler relief valve discharged, the water vapour that reaches boiling point evenly was full of annular compartment 2, through spray-hole 4 water spray in chimney.Along circumferentially some spray-holes being set, water smoke is evenly sprayed on the whole cross section of chimney.Like this, ash-laden gas is subjected to the washing of injection water vapor film, and part grit, harmful substance are separated from the flue gas stream of the discharging of rising, and under the gravity effect, reduces to burning once more in the stove.
The cross section of above-mentioned annular compartment 2 can be a rectangle, circle or semicircle etc.
This device utilizes the waste steam of normal-pressure boiler discharging that a part of grit in the flue is washed away.Thereby also with NO contained in these grits
X, SO
XRemoved.After tested, this device can effectively reduce the concentration of grit and other harmful substance in the flue gas, and has improved efficiency of combustion to a certain extent.Use this device back smoke dust discharge concentration to reduce by 35%, SO2 emissions reduce by 28%, and nitrogen oxide emission has reduced by 35%.In addition, this apparatus structure and technology are simple, do not expend the energy, are fit to supporting various normal-pressure boilers, can further alleviate the pollution of this class boiler to environment.
Claims (2)
