Description
Technical field
The present invention relates to a kind of automatic employing system, relate in particular to a kind of coal sample automated collection systems and control method thereof.
Background technology
Coal is the main fuel source of Power Plant in China always, the quality of Coal Quality directly influences the safe operation of boiler of power plant, the economic benefit that is related to power plant, especially under the soaring year by year overall background of energy prices, the fuel cost of fuel-burning power plant has occupied more than 70% of total cost.Therefore strengthen the Coal Quality management, three links of adopting, make, change in the fuel mass course of receiving are carried out the most important thing that fine-grained management becomes the modern fuels management.Sampling is that first link of gathering and processing is the important foundation of next two links.
The purpose of power plant's coal samling is that sample can reflect the total quality of the coal of gathering for the feasible sample of being gathered has certain representativeness, and the sample system error of being gathered is in the tolerable scope.Hand sampling or mechanical sampling are mostly adopted in China's sampling at present, and the collection of the intact ground of coal sample sample is chosen in hand sampling from the vehicle of going into factory with spade by the sampling work personnel; Mechanical sampling is finished sampling by the sample devices of manual control special use; No matter being artificial sample or mechanical sampling, all is manual storing containers of specifying coal sample after vehicle sampling is finished, and, and the increment of being gathered is delivered between sample making apparatus container number by the field staff.
Mainly there is following problem at present in the sampling process of fuel-burning power plant:
The sampling increment is counted deficiency
Because power plant's roping vehicle is more, the spot sampling task is heavy, and labour intensity is big, hand sampling or mechanical sampling can not be accomplished sampling of car car or a plurality of increments of a car, do not reach the GB requirement fully, cause the increment of sampling to count wretched insufficiency, can not represent supplier's Coal Quality fully.
To adopt mechanical system is the working load that example is calculated spot sampling, certain power plant had 800 roping vehicles in 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, the scene needs 3 Sampling Machine at least, 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 satisfy sampling request, if the vehicle that has needs spot test with a focus on to gather a plurality of increments, when perhaps sample devices breaks down, the on-the-spot requirement that does not just reach the per car sampling, in the process of checking and accepting, can only cause sampling subnumber wretched insufficiency to the sampling of part vehicle.
Sampling point position and sampling depth randomness are relatively poor
Hand sampling or mechanical sampling all need manually to specify sampling location and sampling depth in sampling process, the sample collector carries out determining of sampled point not according to GB, randomness is bigger, and the not enough 0.4m of sampling depth, especially hand sampling, owing to sampling instrument or a lot of personnel of labour intensity reason only adopt surperficial coal seam, gather less than bottom, compartment coal sample, cause institute's collected specimens can not represent the ature of coal of institute's collection vehicle fully.On the other hand, on-the-spot illegal supplier often is positioned over colm, gangue, coal slime the most of zone in bottom, compartment or compartment, collude from both within and without with the spot sampling personnel, only gather the good zone of ature of coal in the compartment during sampling, cause great economic loss to power plant, make the economic dispute of both sides of supply and demand.
Increment lacks confidentiality
No matter be hand sampling or mechanical sampling, after finishing, sample-grabber's sampling all the coal sample of being gathered can be put into sampling container, container number that sample is put into is easy to for the sample collector and will knows, does not have confidentiality, is unfavorable for that the just open justice of the work of chemically examining is carried out.And if illegal supplier colludes with, the increment of being gathered in follow-up sample presentation process or sample making course is substitute easily, and chemical examination process and result are also disturbed easily, causes final result of laboratory test inaccurate, cause economic loss to power plant, influence the economy of power plant benefit.
In addition, at present common Sampling Machine is mainly two kinds of cantilevered Sampling Machine and bridge-type Sampling Machine in the scene, but cantilevered Sampling Machine sample area is less, sample range is the cover tape vehicle of pulling fully, sampling to vehicle need make two bites at a cherry, realize for the first time front compartment sampling, realize trunk sampling for the second time, need vehicle to move the sampling that just can finish the vehicle trunk after having adopted front compartment vehicle to vehicle; The sample range of bridge-type Sampling Machine depends primarily on the length of Sampling Machine cart running rail, if the Sampling Machine track is longer, move the position of sampling cart by track and finish the sampling that pull the front and back of vehicle, if orbital distance can not the cover tape tractor-trailer than weak point before and after the car scope, equally also need moving vehicle to finish sampling to pulling before and after the vehicle.
