Description
Technical field
The utility model belongs to the corrosion and protection technical field of power system, especially by the device that in the rear pass of cigarette tower integrating system absorption tower, easily dust stratification and the deposit that solidifies clean out.
Background technology
Cigarette tower unification technique is that thermal power plant's chimney and cooling tower are united two into one, and cancels chimney, carrys out the flue gas of emission purification, as shown in Figure 1 by cooling tower.On the one hand the clean flue gas of a large amount of Hot wet air heating of this technology utilization cooling tower after to desulfurization forms parcel and lifting, increases the rising height of flue gas, thereby promotes the diffusion of pollutant in flue gas; It also can improve the exhausting ability of cooling tower on the other hand, improves cooling tower cooling effectiveness.But this technique has also been brought new problem simultaneously.In smoke-discharging tower integration device, the flue gas moisture content that is sent to cigarette tower through absorption tower is more, and the slurries in flue gas in residual dust and absorption tower are easily set on fiber glass reinforced plastic smoke flue, and cross section is plane distribution.Dust stratification composition, taking absorption tower sprayed slurry composition as main, accounts for 80%, and all the other are coal-fired ash.Dust stratification is present in flue with mud form, relatively less near the dust stratification moisture of absorption tower part.When particularly break down in the absorption tower before flue, fouling phenomenon is more obvious.Dust stratification after deposition can make desulfurizing tower for a long time fiber glass reinforced plastic smoke flue fouling serious, cause fiber glass reinforced plastic smoke flue to break and even collapse.
Utility model content
The utility model is mainly by increasing specific detergent line and nozzle in desulfurization rear pass, reaching the object of the mud of the interior accumulation that cleans flues, thereby avoids the accident that leakage occurs and cave in fiber glass reinforced plastic smoke flue.
The technical scheme in the invention for solving the technical problem is: this kind of cigarette tower unification desulfurization rear pass ash handling equipment, comprise desulfurizing tower, pipeline and cooling tower, it is characterized in that, what described pipeline tilted is arranged between desulfurizing tower and cooling tower, and the exhanst gas outlet of described pipeline in cooling tower is higher than gas approach in desulfurizing tower;
In described pipeline, be furnished with a branch of shower with identical water pressure, and a nozzle is installed in the water side at each shower, described nozzle is arranged along the circumferentially even interval of GRP pipe, and described nozzle comes to also downward-sloping setting towards flue gas, and the water inlet end of all showers is successively by being connected to clear water source after main pipeline, valve and water pump.
Best, described pipeline gradient is 1.5%.
Further, described clear water source is the industry water pipeline from plant area.
Further, described shower is PPR water pipe, and ties up bunchy by Plastic Bandage.
Best, downward-sloping 8 degree of described nozzle.
Further, described nozzle is the flat nozzle that can spray fan-shaped water smoke, and setting height(from bottom) is that jet expansion distance is treated 10 centimetres of flushing pipe low sides.
Further, described nozzle angle degree is adjustable.
Further, described pipeline is GRP pipe.
Further, described pipeline is that the concrete prefabricated pipeline of multistage is spliced and adopts PUR sealing in stitching portion, is provided with anticorrosive coat at described concrete duct inner surface.
The beneficial effects of the utility model are: the utility model adopts built-in nozzle cleaning system, effectively reduce the deposition of mud on flue surface, have indirectly reduced maintenance cost, flue resistance and flue weight, ensure the safe operation of cigarette tower integrating system.

Detailed description of the invention
As shown in Figures 2 to 7, this kind of cigarette tower unification desulfurization rear pass ash handling equipment, comprises desulfurizing tower, GRP pipe and cooling tower.
Wherein, desulfurizing tower is the occasion of flue gas being carried out to desulfurization, and the device such as demister and spiral board is contained in inside.
Cooling tower, need to carry out structure of modification and do preservative treatment it, the clean flue gas after utilizing Hot wet air heating that cooling tower is huge to desulfurization forms a ring-type air curtain, and clean flue gas after desulfurization is formed to parcel and lifting, increase the rising height of flue gas, thereby promote the diffusion of pollutant in flue gas.
What described GRP pipe tilted is arranged between desulfurizing tower and cooling tower, and GRP pipe gradient is 1.5%, and the exhanst gas outlet of described GRP pipe in cooling tower is higher than gas approach in desulfurizing tower; Desulfurizing tower clean gas out can be drawn and exported in cooling tower.Flushing water flows to absorption tower from cooling tower, flows to lower from eminence, and developing result is more obvious.
The antiseptic property of GRP pipe is better, but intensity is poor, so above-mentioned pipeline also can adopt concrete prefabricated pipeline to design, concrete, for the concrete prefabricated pipeline of multistage is spliced and adopts PUR sealing in stitching portion, be provided with anticorrosive coat at described concrete duct inner surface.No matter adopt which kind of pipeline, be all fine.
In the course of work, owing to containing the more and slurries of certain moisture in GRP pipe 1, slurries in flue gas in residual dust and absorption tower are easily set on GRP pipe 1, need regular it is removed, and this device is exactly a solution on this basis.
First, with PPR water pipe making shower 2, and tie up bunchy by Plastic Bandage, be convenient to like this connect up in GRP pipe inside, a nozzle 3 is installed in water side at each shower, and described nozzle is arranged along the circumferentially even interval of GRP pipe, generally arranged one at interval of 5 meters, form the nozzle injection point of some row, and the flushing pressure of each injection point is identical.Shower 2 is selected PPR (atactic copolymerized polypropene), can not only meet requirement for anticorrosion, and quick and easy for installation.
When mounted, can increase steel skeleton nozzle and shower are supported, and each nozzle be towards flue gas come to and downward-sloping setting, for example angle of inclination is 8 degree.The water inlet end of all showers by being connected to the industry water pipeline 6 from plant area after main pipeline 4, valve and water pump 5, provides spray-water successively.Water pump is two, with one for one.
Best a kind of nozzle pattern is: nozzle 3 is for spraying the flat nozzle of fan-shaped water smoke, and setting height(from bottom) is 10 centimetres of jet expansion distance GRP pipe low sides to be rinsed, the nozzle spraying width of this shape and spraying intensity maximum, and developing result is also best.
By mounting means and the position of nozzle are set, can realize nozzle angle degree adjustable, as shown in Figure 4.
Except the technical characterictic described in description, be the known technology of those skilled in the art.
