Description
Technical field
The utility model relates to coal sample pick-up unit technical field, particularly relates to a kind of drying box.
Background technology
The chemical composition of coal is made up of organic hydrocarbons and dead matter, and the moisture wherein in coal holds labile component most.The moisture of coal is the most basic index evaluating Coal Economy value, because the change of moisture in coal can cause the content of other component or the change of thermal value, produces certain impact to the inspection matter, metering, examination, management etc. of coal.When having large quantity of moisture in coal, not only the useful component of coal reduces, and large quantity of moisture is when burning simultaneously, absorb a large amount of heat to become water vapor and evaporated in vain, and exhaust gas volumn is increased, increase the energy consumption of flue gas loss and exhaust blower, the impact of moisture on burning is also larger than ash content according to statistics.Moisture is non-flammable composition in coal, and the moisture of coal is more, and the useless composition of coal is more, and the moisture in coal is larger also just means that also many non-combustible compositions transport power plant, thus adds clearing quantity.Weigh fuel management level height in electricity power enterprise, wherein binomial important indicator enter exactly factory's coal with as-fired coal calorific value poor and profit and loss situation of making an inventory.And these two indexs are closely bound up with moisture.Such as, calorific value difference is the mathematic interpolation gained after being weighted according to the net calorific value as received basis and quantity that enter factory's coal and as-fired coal, as aforementioned net calorific value as received basis and quantity are all relevant with total moisture, the larger calorific value of total moisture is lower, so when entering factory's coal and as-fired coal total moisture difference is excessive, the calculated distortion of calorific value difference will be caused.Some power plant adopts dry base heat value data to valuate (inner accounting), to eliminate the objective impact of moisture on calorific value at present.
The moisture of coal also directly affects the use of coal, transport and storage.The moisture of coal increases, and in coal, useful component reduces relatively, and moisture becomes steam when burning will absorb heat, and thus reduces the thermal value of coal.The moisture of coal increases, and also add ineffective traffic, and brings difficulty to unloading.Particularly winter cold district, often freeze car, impact is unloaded, impact produce, affect railway carriage have enough to meet the need, exacerbate the anxiety of transport.The moisture of coal also easily causes coal glue storehouse and reduce bunkering capacity, and stifled storehouse accident even occurs.
Therefore, Accurate Determining moisture in coal to power production management and operation control significant.Traditional full aquametry all measures in the ature of coal Kinds of Moisture Monitors in laboratory.First to sample and sample preparation to coal sample, then the coal sample made be taked certain to prevent from the measure of moisture loss from delivering to laboratory chemically examining.But in sample preparation, particularly coal sample is delivered in the process in laboratory, inevitably there will be the loss of moisture, cause Lower result, serious economic loss is caused to power plant.Best measure is that the step surveying total moisture is moved on to sample preparation scene, the coal sample just having made sample is done to the mensuration of total moisture, can greatly reduce the loss of coal sample moisture in the process being sent to laboratory like this.
At present, measure full water in laboratory and mainly adopt thermogravimetry (TG), namely drying is carried out to the coal sample that certain mass is representative, using the weight of coal sample minimizing as water cut.Thermogravimetry (TG) needs drying device, and drying device main in current laboratory is: electric heating constant-temperature blowing drying box.Electric heating constant-temperature blowing drying box needs sample manually and record data at every turn, and automaticity is low, needs Attended mode, and efficiency is not high, also can not move the on-the-spot mensuration of coal sample being carried out to full water of sample preparation to.
Therefore, how providing a kind of drying box, to increase work efficiency, is current those skilled in the art technical matterss urgently to be resolved hurrily.
