Background technology
In recent years, thermal power plant construction project in all parts of the country is a lot of, and to large-scale, high pressure high temperature turbosets and production domesticization
Direction develop, meanwhile, to environmental protection requirement increasingly improve, the requirement of the emission control to pollutants such as waste water,wastes gas and industrial residue
Also increasingly stricter, the environmental issue of pulp water discharge is less paid attention in conventional thermal power plant, and present pulp water discharge will be passed through tight
Lattice processing, could reuse or discharge after up to standard.
At present, domestic pulp water processing method typically uses the processing methods such as sedimentation basin, thickener, ceramic filter tiles pond,
There are a small number of producers by the way of flocculation sediment+inclined tube+sand is considered.Above-mentioned treatment technology there is it is various the problem of, such as account for
Ground and product is big, technique chain length, the clarification time is long, energy consumption loss is high, effluent characteristics are poor, equipment pipe plinth and operation and maintenance are big etc.
Shortcoming.And pulp water chemical processing system can bring secondary pollution, by badly damaged residue extraction mechanism in the case of using improperly.
Utility model content
The utility model provides a kind of slag water treatment system, by will between pulp water pump and dragveyer establish in circulation with
Afterwards, pulp water can be effectively handled, alleviates Slag-water system pulp water imbalance problem, reduces energy consumption, solving thermal power plant will be efficiently dense
When the slurries that contracting machine concentrating and separating goes out return dragveyer by slurry pump, the stifled slurry of high-efficient compressor is caused seriously, main rake can not be transported
OK, the problem of separation of slurries can not be realized.
The utility model is achieved by the following technical programs.
A kind of slag water treatment system of thermal power plant, including it is dragveyer, slag runner, slurry pond, pulp water pump, high-efficiency concentrator, clear
Clear pond, small pump, the outlet pipeline of the dragveyer are connected to slag runner；The slag runner is connected to slurry pond；The slurry pond connects
It is connected to pulp water pump；The pulp water pump connects high-efficiency concentrator；The outlet pipeline of the pulp water pump is connected to dragveyer, is followed in composition
Ring, the pulp water that slurry pond treats is recycled in dragveyer；The high-efficiency concentrator outlet pipeline is connected to depositing reservoir；It is described
Depositing reservoir is connected to small pump；The outlet pipeline of the small pump is connected to dragveyer.
Further, the water pipe of the dragveyer is equipped with electrically operated gate, and the outlet pipe of the water pipe and small pump
Road is connected.
Further, the pulp water flowed into the slag runner is mainly dragveyer overflow water, slag storehouse flushing water.
Further, the outlet pipeline of the depositing reservoir is also connected to slurry pump, the outlet pipeline connection of the slurry pump
To high-efficiency concentrator.
Further, described dragveyer is on the bow respectively provided with water-level gauge and thermometer in tail both ends.
Further, the guide wheel of the dragveyer is external.
Further, some filter screens, mixing plant are installed in the slurry pond
The beneficial effects of the utility model are：
1st, Slag-water system efficient, lasting can be handled pulp water, reduces the loss to equipment.
The slag water treatment system of thermal power plant was originally designed as directly being beaten pulp water in slurry pond to efficiently dense with pulp water pump
Enter depositing reservoir after the processing system processing of contracting machine, then returned by small pump to dragveyer, cause long-term a large amount of pulp waters to beat to dense
Contracting machine, cause stifled slurry seriously, main rake can not be run, and can not realize the separation of slurries, be caused inside high-efficiency concentrator and depositing reservoir
A large amount of accumulated slags, the safety of equipment is had a strong impact on.The outlet pipeline of pulp water pump is connected to dragveyer by designing now, can be with
Circulated in forming, the pulp water that slurry pond treats is recycled in dragveyer, the use to high-efficiency concentrator is reduced, reduces this and set
Standby loss.
2nd, intelligentized moisturizing can be realized, reduces energy consumption
Pulp water water pump outlet pipe road in Slag-water system of the present utility model is connected to dragveyer, the slag that slurry pond is treated
Water circulation is into dragveyer；When only pit level is too high in slurry pond or when dragveyer water level exceedes early warning water level, the company of unlatching
High-efficiency concentrator is connected to, can be that slurry pump is in long-term stoppage in transit state, water is used needed for itself when reducing plasma discharge pump startup
Amount, systematic water balance is kept, and saved station service.Simultaneously equipped with electrically operated gate and moisturizing is connected with the water pipe of dragveyer
The water return pipeline of pump, small pump can be realized that water level is low and open water supplement function when dragveyer water level is less than early warning water level.
