Description
Technical field
It the utility model is related to a kind of blow-off pipe, and in particular to a kind of easy dredging, visualization for wet desulfurization system
New blow-off pipe.
Background technology
Coal is the main energy sources in China, and by the end of the year 2015, thermoelectricity installed capacity in the whole nation will have reached 9.5 hundred million kilowatts, account for electricity
The 68% of power installation total amount, and in the following quite a long time, supply of electric power general layout of the China based on coal fired power generation
Basic change will not occur.Coal-burning power plant is the important emission source of various pollutants in China's air simultaneously, according to statistics, about
90% SO2, 67% NOXSource of Dust with 70% is in coal fired power generation.With increasingly raising of the people to environmental requirement, pin
To the increasingly strict of coal-burning power plant's pollutant emission, it is proposed that thermal power generation minimum discharge standard.Gypsum Wet flue gas
Desulfurization (WFGD) technology is used as presently the most effective coal unit SO2Emission control technique, there is desulfuration efficiency height, operation phase
To it is reliable, good to coal adaptability the features such as, be widely used in coal fired power plant flue gas desulfurization.
Many slurries conveyance conduits, including slurry circulating pump pipeline, limestone slurry liquid pump in wet desulfurization system be present
Pipeline, gypsum excavationg pump pipeline, filtrate water pump pipeline etc., these pipelines are used to convey accordingly in desulphurization system running
Slurries, then need during stoppage in transit to empty remaining slurries in pipeline, and it is using process water that pipe flushing is clean, to prevent slurries from conveying
Pipeline scale blocks influence system normal operation.But there is following major defect in existing blow-off pipe：
1) blow-off pipe is opaque.Because pit-hole existing for regulation field ground must be spread in wet desulfurization system safety code
If the firm cover plate flushed with ground, to prevent occurring personnel's fallen accident, therefore blow-off pipe go to the low-lying place of melt pit use it is firm
Cover plate covers.When needing to empty in slurries in pipeline after slurries delivery pipe deactivation, due to the opaque design of blow-off pipe, cause not
Be easy to observe blow-off pipe whether excessively stream.Simultaneously when being rinsed emptying to pipeline, it is also not susceptible to observe whether excessively stream is clear stream
To judge whether pipe flushing is thorough.
2) blowdown blockage is not easily cleaned.Because what is conveyed in wet desulfurization system pipeline is that limestone-gypsum mixes mostly
Slurries are closed, the slurries have the characteristic of easily accumulation precipitation, and the blow-off pipe of each slurries conveyance conduit is generally in relative low level
Put, cause blow-off line easily to block.If being not easily cleaned after blowdown blockage, may influence the normal of slurries conveyance conduit makes
With so as to run generation interference to whole desulphurization system.
3) it is not easy to be sampled analysis to slurries in pipeline.At present during sampling, there are two kinds of sampling methods mostly, first,
Slurry tank designs special sample tap, while sets up flushing water to ensure that sampling pipe is unobstructed；Second, blowoff valve is opened, and adjust
Blowdown valve opening is saved, sampling bottle then is placed in into the blow-off pipe mouth of pipe is sampled.Both sampling methods, otherwise design is multiple
It is miscellaneous, increase construction cost, or operation is complex, potential safety hazard be present.
Utility model content

Center and both ends insertion hollow-core construction, a solid bolt is detachably connected by the hollow-core construction；
One transparent lucite tube, it is connected with rubber-lined pipe by a flange, a blowoff valve is provided with the flange connections.
Further, rubber-lined pipe includes a stainless steel tube, and one layer of elastomeric material is lined with the stainless steel inside pipe wall.
Further, the stainless steel tube of rubber-lined pipe welds with slurries delivery pipe.
Further, the through-hole wall of bulge-structure contains the screw thread being engaged with the screw thread of hollow bolt, bulge-structure
It is threadedly coupled with hollow bolt.
Further, the hollow-core construction inwall of hollow bolt contains the screw thread being engaged with the screw thread of solid bolt, hollow
Bolt is connected with solid bolt thread.
Further, blowoff valve is handle type butterfly valve.
Further, bulge-structure, hollow bolt and solid bolt are stainless steel material.
The beneficial effects of the utility model are：
1st, blow-off pipe overcurrent condition can be directly observed through transparent lucite tube, judges whether blow-off pipe blocks, together
When using flushing water heel row space-time is rinsed to slurries delivery pipe, by observing lucite tube current clean-up performance and pipe
The clean level of wall, you can judge whether slurries delivery pipe rinses thoroughly.
2nd, rotation hollow bolt brings it about displacement, passes in and out inside rubber-lined pipe, the deposition obturator that can be cleared up in blow-off pipe,
Reach the effect easily dredged, while periodically rotate hollow bolt to slow down blow-off pipe blockage problem.
3rd, slurries can be flowed out by the hollow-core construction of hollow bolt, conveniently be sampled detection.
4th, hollow bolt and solid bolt are detachable, are easy to cleaning and change.
