Background technology
Along with industrial expansion, demand to electric power increases day by day, the mode of generating is diversified, hydropower, thermal electric generation, nuclear power, solar electrical energy generation and generation of electricity by new energy etc., but China's electric power major part is take thermal electric generation as source at present, through the development of more than 100 years, thermal power generating technology is full maturity, it is failure-free power source, but along with the deterioration of earth environment, country is more and more higher to the requirement of environmental protection, energy-saving and emission-reduction, and anti-emission carburetor, zero is polluted the basic demand that has become enterprise development.And thermal electric generation is using fire coal as fuel, itself environment is had pollution except coal-fired, after burning, produce fly ash and contain the flue gases such as sulfide, environment is all caused to gross pollution, wherein the reasonable actv. utilization of fly ash has become a kind of urgent environmental demands.
After coal-fired power plant burning, produce a large amount of fly ash, fly ash as a kind of building materials and road and bridge material can well recycle, through years development, traditional mode of utilizing generally has two kinds, the first is, build large-area permanent ash, forever stack, this processing mode need to take a large amount of soils, and to carry out impermeable processing to ground, nonetheless coal ash can also can pollute earthing water under the effect of rainwater, airborne dust can pollute surrounding environment, the process Zhong Yehuidui highway of transhipment environment around causes secondary pollution, second method is, be transported to construction of road and bridge building site, pave the way, as roadbed material, or be transported to brick field, do machine made brick, this method needs far away or near transhipment, increases business economic cost, cuts power plant and need to build grey storehouse, also increase the operation cost of electricity power enterprise, in transportation, also can cause dust pollution to surrounding environment.
Utility model content
The purpose of this utility model is to provide a kind of fly ash air-transport system, realizes the dry type of fly ash and carries, and reduces wet row or the pollution of water punching ash to environment, for follow-up exploitation provide good basis.
For realizing above object, the utility model provides a kind of fly ash air-transport system, comprise ash bucket, compressed air system, sending set, Hui Ku, the exhausr port of compressed air system connects sending set, sending set comprises transmitter, the ash charge mouth of transmitter connects the ash discharging hole of ash bucket, and the outlet of transmitter connects top, grey Kuku by pipeline.
Further, in compressed air system, comprise air compressor, drier, air filter.
Further, sending set also comprises charging dome valve and bleeder valve, and charging dome valve is arranged on transmitter top, and bleeder valve is arranged on transmitter outlet, is also provided with level-sensing device and pressure transformer on transmitter.
Further, the pipeline that transmitter exports between top, grey Kuku adopts wear-resistant pipe.
The raw material of cement needs a large amount of raw grogs, fly ash be good raw material sources, fully actv. utilizes the fly ash that power plant for self-supply or boiler of power plant burning nearby produce, can be delivered in cement line raw material cabin by pipeline, the fly ash that the abundant actv. of the utility model utilizes boiler combustion to produce, be delivered in raw material cabin by pipeline, this comprehensive application mode is particularly convenient for the power plant for self-supply of cement mill, by convenient, the economic conveying of pipeline, reduce intermediate link, reduced pollution on the environment.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model system construction drawing
In figure: 1 ash bucket, 2 compressed air systems, 3 grey storehouses, 4 transmitters, 5 charging dome valves, 6 bleeder valves
The specific embodiment
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
embodiment 1:
With reference to Fig. 1, the utility model provides a kind of fly ash air-transport system, comprise ash bucket 1, compressed air system 2, sending set, grey storehouse 3, the exhausr port of compressed air system 2 connects sending set, sending set comprises transmitter 4, the ash charge mouth of transmitter 4 connects the ash discharging hole of ash bucket 1, and the outlet of transmitter 4 connects 3 tops, storehouse, grey storehouse by pipeline.
Preferably, in compressed air system 2, comprise air compressor, drier, air filter.
Preferably, sending set also comprises charging dome valve 5 and bleeder valve 6, and charging dome valve 5 is arranged on transmitter 4 tops, and bleeder valve 6 is arranged on transmitter 4 and exports, and is also provided with level-sensing device and pressure transformer on transmitter 4.
Preferably, the pipeline that transmitter 4 exports between 3 tops, storehouse, grey storehouse adopts wear-resistant pipe.
In the flue gas producing after boiler combustion, contain a large amount of particulate matters, enter dust exhaustor by rear pass, particle in flue gas is filtered after absorption by dust collecting fan, be collected in ash bucket 1, by opening the charging dome valve 5 on the transmitter 4 under ash bucket 1, dry ash is fallen in transmitter 4 successively, in the time being accumulated to certain capacity,, in grey storehouse, recycle as cement raw material by compressed air delivery.Concrete course of conveying is: close charging dome valve 5, open the pneumatic valve on admission line, utilize pressurized air that the coal ash in transmitter 4 is transported in grey storehouse 3 by ash pipe.There is exhaust gear transmitter 4 tops, in fly ash dropping process, interior transmitter 4 air are entered to ash bucket 1, guarantee that ash is smooth and easy, and ash handing pipeline is provided with bypass companion and blows system, utilizes pressurized air to strengthen and to sweep pressure, prevents that pipeline from stopping up in defeated grey process.Wherein carrying ash pipe is thickening pipeline, and elbow adopts wear-resistant bend, reduces the wearing and tearing of fly ash to pipeline, extends system service life.
