Description
Technical field
The present invention relates to a kind of employing system automatically, relate in particular to a kind of coal sample automatic acquisition system and control method thereof.
Background technology
Coal is the main fuel source of Power Plant in China always, the quality of Coal Quality directly affects the safe operation of boiler of power plant, be related to the economic benefit of power plant, especially, under the overall background riseing year by year in energy prices, the fuel cost of fuel-burning power plant has occupied the more than 70% of total cost.Therefore strengthen coal quality management, three links of adopting, make, change in the fuel mass course of receiving are carried out fine-grained management and become the most important thing of modern fuels management.Sampling is that first link of gathering and processing is the important foundation of two links next.
The object of power plant's coal samling is that sample can reflect the total quality of gathered coal in order to make gathered sample have certain representativeness, and the sample system error gathering is within the scope of tolerable.China's sampling at present mostly adopts hand sampling or mechanical sampling, and the collection of the complete ground of coal sample sample is chosen in hand sampling from entering the vehicle of factory with spade by sampling work personnel; Mechanical sampling completes sampling by the special sample devices of manual control; No matter being artificial sample or mechanical sampling, is all manual storing containers of specifying coal sample after vehicle has sampled, and, and gathered increment is delivered between sample making apparatus container number by field staff.
In the sampling process of fuel-burning power plant, mainly there is at present following problem:
Sampling increment is counted deficiency
Because power plant's roping vehicle is more, spot sampling task weight, labour intensity is large, hand sampling or mechanical sampling can not be accomplished the sampling of car car or the multiple increments of a car, do not reach GB requirement completely, cause the increment of sampling to count wretched insufficiency, can not represent supplier's Coal Quality completely.
To adopt the working load of mechanical system as example calculating spot sampling, certain power plant has 800 roping vehicles for one day, the coal sample of a car of collection 5 minutes, needed hourage is: 800*5/60=67, all to sample if accomplish each car, scene at least needs 3 Sampling Machine, every Sampling Machine working time is: 67/3=22.3 hour, meaning that field personnel's needs one day 24 hours are on duty could meet sampling request, if some vehicles need spot test with a focus on to gather multiple increments, or when sample devices breaks down, the on-the-spot requirement that does not just reach per car sampling, in the process of checking and accepting, can only sample to part vehicle, cause sampling subnumber wretched insufficiency.
Sampling point position and sampling depth randomness are poor
In sampling process, hand sampling or mechanical sampling all need manually to specify sampling location and sampling depth, sample collector carries out determining of sampled point not according to GB, randomness is larger, and sampling depth deficiency 0.4m, especially hand sampling, because sampling instrument or a lot of personnel of labour intensity reason only adopt surperficial coal seam, do not collect car bottom coal sample, cause institute's collected specimens can not represent the ature of coal of institute's collection vehicle completely.On the other hand, on-the-spot illegal supplier is often positioned over colm, gangue, coal slime the most of region of car bottom or compartment, collude from both within and without with spot sampling personnel, when sampling, only gather the good region of ature of coal in compartment, cause great economic loss to power plant, manufacture the economic dispute of both sides of supply and demand.
Increment lacks confidentiality
No matter be hand sampling or mechanical sampling, after having sampled, sample-grabber all gathered coal sample can be put into sampling container, container number that sample is put into is easy to know do not have confidentiality for sample collector, is unfavorable for that the just open justice of the work of chemically examining is carried out.If with illegal supplier colludes with, the increment gathering in follow-up sample presentation process or sample making course is easily substitute, and procedure and result are also easily disturbed, causes final result of laboratory test inaccurate, cause economic loss to power plant, affect economy of power plant benefit.
In addition, at present in scene, common Sampling Machine is mainly two kinds of cantilevered Sampling Machine and bridge-type Sampling Machine, but cantilevered Sampling Machine sample area is less, the sample range vehicle that cover tape is pulled completely, need to make two bites at a cherry to the sampling of vehicle, realize for the first time the front compartment sampling to vehicle, realize for the second time the trunk sampling to vehicle, need vehicle mobile just can complete the sampling to vehicle trunk after having adopted front compartment; The sample range of bridge-type Sampling Machine depends primarily on the length of Sampling Machine cart running rail, if Sampling Machine track is longer, complete by the sample position of cart of rail moving the sampling that pull the front and back of vehicle, if orbital distance is shorter can not cover tape tractor-trailer before and after car scope, equally also need moving vehicle to complete the sampling to pulling before and after vehicle.
