Abstract
The utility model discloses a pneumatic ash-removing compressed-air delivery system, comprising an air compressor and an air storage tank, wherein an air outlet of the air compressor is connected with an air inlet of the air storage tank. A valve is arranged on an air path between the air compressor and the air storage tank. In the pneumatic ash-removing compressed-air delivery system, the investment cost at the initial stage is reduced, the energy consumption of equipment is reduced and the utilization efficiency of the compressed air is improved.
Description
Technical field:
The utility model relates to thermal powerplant energy saving retrofit technology field, and particularly a kind of energy-conservation pneumatic ash handling in the thermal electric generation deashing device is carried compressed air system.
Background technology:
In the thermal powerplant pneumatic ash removal system, carrying compressed air system air compressor, drier is the equipment of power consumption very in the system.How reducing this part electricity consumption of equipment rate, reduce station service power consumption rate, is one of focus of each power plant's energy conservation.
Carry in the compressed air system at existing thermal power plant pneumatic ash handling, as shown in Figure 1, generally comprise air compressor 100, drier 300, storage tank 200.Wherein, Air compressor is the propulsion source of pneumatic ash removal system, and its rating horsepower is bigger, is example with separate unit 300WM unit; The ash disposal air compression acc power of being joined is about 280kW; In the deashing device of normal operation, air compressor 100 is in the state of continuous operation, has therefore consumed a large amount of electric energy.When using air compressor 100, when delivery pressure one timing, the tolerance and the power of air compressor 100 are directly proportional, and the big more cooresponding power of tolerance is just big more.If tolerance loss in ash disposal system is little, cooresponding air compressor 100 tolerance will reduce, and the power of air compressor 100 will correspondingly reduce like this.Drier 300 when pressurized air is carried out dry decontamination, the tolerance of consumed cabin air compressor 100 outlet big (generally consume 10～15% tolerance), the increase that this just can't help the cost input in power plant.
The utility model content:
In order to address the above problem, the utility model provides a kind of pneumatic ash handling capable of reducing energy consumption to carry compressed air system.
The technical scheme of the utility model is: pneumatic ash handling is carried compressed air system, and it is characterized in that: comprise air compressor and storage tank, the air outlet of said air compressor links to each other with the storage tank admission port.
On the gas circuit between said air compressor and the storage tank valve is installed.
On gas circuit between the said air compressor, the gas circuit between the storage tank valve is installed.
The beneficial effect of the utility model is: the utility model has reduced equipment energy consumption; Having improved the pressurized air utilization ratio, reduced the initial investment cost, is example with 2 * 300MW unit; Can practice thrift equipment investment 3 * 150,000 yuan; Practice thrift about 2 * 30,000 yuan of drier power consumption expense (drier power 12kW, power plant's year operation 6500h, 0.4 yuan/degree of electricity price).Air compressor can reduce the flow that drier consumes when type selecting, the reduction of air compression acc power is about 60kW, about 2 * 15.6 ten thousand yuan of power consumption expense like this.So, practice thrift cost and be about 82.2 ten thousand yuan/year.In sum, utilize the utility model to reduce the initial investment cost, reduced equipment energy consumption, improved the pressurized air utilization ratio.In addition, reduce the system controlling point, maintain easily maintenance.
Description of drawings:
Fig. 1 is the existing 2 * 300WM of thermal power plant unit ash disposal compressed air system scheme drawing;
Fig. 2 is the 2 * 300WM of the thermal power plant unit ash disposal compressed air system scheme drawing of the utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 2, pneumatic ash handling is carried compressed air system, comprises air compressor 100 and storage tank 200, and the air outlet of air compressor 100 links to each other with storage tank 200 admission ports, on the gas circuit between air compressor 100 and the storage tank 200 valve is installed.This system comprises an air compressor 100 and a storage tank at least, if two above air compressors 100 or two above storage tanks 200 then are equipped with valve on the gas circuit between the gas circuit between the air compressor 100, the storage tank 200.
In the prior art, drier when pressurized air is carried out dry decontamination, the tolerance of consumed cabin air compressor outlet big (generally consume 10～15% tolerance); And air compressor temperature out under nominal air delivery is about 85 ℃; Under this temperature, in the pressurized air of air compressor output moisture seldom, and the dust stratification temperature in the electric dust collector is at 110～130 ℃; The dust stratification temperature is also more than 100 ℃ in the entering ash disposal system; The pressurized air that contains minor amount of water is when purging 100 ℃ of dust stratifications, and water will directly be vaporized, and can not influence whole pneumatic ash removal system.
More than show and described the advantage of groundwork, principal character and the utility model of the utility model.The technical personnel of the industry should be understood; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
