Description

For the de-watering apparatus of boiler smoke
Technical field
The utility model relates to flue gas and to dewater field, is specially a kind of de-watering apparatus for boiler smoke.
Background technology
Containing a large amount of SO in the flue gas that in boiler, the burning of coal produces 2, SO 3, H 2sO 4deng sour gas, in the process that flue gas flows in chimney, water vapour easily condenses into water, and the SO in flue gas 2, SO 3, H 2sO 4be mixed into acidic liquid Deng sour gas, corrosion is caused to chimney, when the gas not forming acidic liquid is discharged in air, also can cause pollution to a certain degree to air.
Although patent in the past to a certain extent, eliminate the moisture in flue gas, and eliminate the SO be dissolved in water in the lump 2, SO 3, H 2sO 4deng sour gas, moisture flows out from delivery port, but in the process of devaporation Cheng Shui, can be agglomerated on de Laval noz(zle) by a part of dust, add the sour gas wherein dissolved, be deposited on the inwall of de Laval noz(zle) for a long time, easily result in blockage, water rem oval declines, if unloaded cleaning, more loaded down with trivial details, and easily damage is caused to de Laval noz(zle) in the process of dismounting, installation, shorten its service life.
Summary of the invention
The utility model, for above weak point, provides a kind of de-watering apparatus for boiler smoke, and it by the water removing in boiler smoke, can not have water, the SO in flue gas 2, SO 3, H 2sO 4acidic liquid would not be formed by dissolving Deng sour gas, avoid and corrosion is caused to boiler chimney.
The utility model solves the technical scheme that its technical problem adopts: a kind of de-watering apparatus for boiler smoke, include de Laval noz(zle), described de Laval noz(zle) one end is connected on the outlet flue of boiler, the other end is connected with heat exchanger, the described heat exchanger other end is connected with air-introduced machine and chimney, described de Laval noz(zle) is provided with delivery port, it is wide that the aperture of described de Laval noz(zle) is set to middle narrow two ends, it is characterized in that: the end position that described de Laval noz(zle) is set to be connected with outlet flue is low, the end position be connected with heat exchanger is high, described de Laval noz(zle) inside is provided with auger conveyor, the rotating shaft of described auger conveyor connects outside stepper motor by power line, described auger conveyor is adapted to the shape of de Laval noz(zle), be close to de Laval noz(zle) inwall, the flight of described auger conveyor is provided with hole for water spraying, hole for water spraying connects outside water jet pump.
Further, described delivery port is arranged at the narrowest place of de Laval noz(zle) median pore radius.
Further, described auger conveyor is arranged at the narrowest place of de Laval noz(zle) median pore radius.
The utility model is provided with de Laval noz(zle), and after flue gas arrives de Laval noz(zle), because its two ends are wide, middle narrow, flue gas has the widest part to arrive narrow place, and speed is accelerated, and pressure reduces, water recovery Cheng Shui, the SO simultaneously will existed in flue gas 2, SO 3, H 2sO 4dissolve together Deng sour gas, form acid solution and flow away from delivery port, thus avoid the corrosion to chimney, extend the service life of chimney; Be provided with heat exchanger, the exchange of heat can be accelerated, promote the condensation of steam.
Accompanying drawing explanation
It is structural representation of the present utility model shown in Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Be illustrated in figure 1 a specific embodiment of the present utility model, a kind of de-watering apparatus for boiler smoke, include de Laval noz(zle) 1, described de Laval noz(zle) 1 one end is connected on the outlet flue of boiler 4, the other end is connected with heat exchanger 2, described heat exchanger 2 other end is connected with air-introduced machine and chimney 5, described de Laval noz(zle) 1 is provided with delivery port 3, it is wide that the aperture of described de Laval noz(zle) 1 is set to middle narrow two ends, the end position that described de Laval noz(zle) 1 is set to be connected with outlet flue 4 is low, the end position be connected with heat exchanger 2 is high, described de Laval noz(zle) 1 inside is provided with auger conveyor 6, auger conveyor 6 includes rotating shaft and flight, described rotating shaft is uniformly distributed with flight, the rotating shaft of described auger conveyor 6 connects outside stepper motor 7 by power line, described auger conveyor 6 is adapted to the shape of de Laval noz(zle) 1, bend along with the bending of de Laval noz(zle) 1, flight in auger conveyor 6 be close to de Laval noz(zle) 1 inwall, the flight of described auger conveyor 6 is provided with hole for water spraying, hole for water spraying connects outside water jet pump, described delivery port 3 and auger conveyor 6 are arranged at the narrowest place of de Laval noz(zle) 1 median pore radius, auger conveyor 6 has sealing function.
When we use the utility model, the flue gas that boiler 4 burning produces enters de Laval noz(zle) 1 by outlet flue, in time flowing to the place that median pore radius is narrow in the place that flue gas is wide from the aperture of de Laval noz(zle) 1, the flowing velocity of flue gas increases, pressure reduces, steam in flue gas condenses into water, and the SO will contained in flue gas 2, SO 3, H 2sO 4dissolve together Deng sour gas and dust, de Laval noz(zle) 1 shape is curved shape, front end is positioned at low level relative to rear portion being positioned at, go out water from fume gas condensation to flow out from delivery port 3 under Gravitative Loads, avoid being continued to walk backward by flue gas, because in flue gas, steam condenses into water, sour gas has also been pulled away to cause heating surface and chimney and has corroded.Significantly can lower exhaust gas temperature like this, exhaust gas temperature often reduces by 10 DEG C, and boiler thermal output can improve 1%;
After de Laval noz(zle) 1 uses a period of time, inside pipe wall has certain deposit, at this moment, we can start stepper motor, and stepper motor drives the rotating shaft of auger conveyor 6 to rotate, thus drives flight to rotate, dispose the deposit be deposited on inside pipe wall, deposit flows out from delivery port 3, continues like this to use, and can keep the maximum efficiency of de Laval noz(zle) 1.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
