Abstract
The invention relates to the technical field of coal sample detection devices, in particular to a drying oven for protective gas. The drying oven for protective gas comprises multiple drying cavities, and a heating element and a gas inlet pipe are arranged in each drying cavity. The drying oven for protective gas further comprises a control unit, and the control unit is used for controlling the heating rate of each heating element and the gas inlet amount of each gas inlet pipe. The drying oven for protective gas is provided with the multiple drying cavities, multiple samples can be placed in different drying cavities to be dried respectively in a coal sample drying test, it is avoided that in the prior art, all samples are placed in the same drying cavity and drying can not be finished unless the sample with the largest moisture content is dried, and the test time for drying multiple samples with different moisture contents is shortened; the multiple drying cavities are independent of one another, and thus the working efficiency can be improved; besides, when the number of samples is small, the samples are placed in one drying cavity, heating and gas introducing are not needed for other drying cavities, and thus heating electricity consumption and nitrogen consumption are reduced.
Description
Technical field
The present invention relates to coal sample detection device technique field, particularly relate to a kind of protective gas and be dried
Case.
Background technology
The chemical composition of coal is made up of organic hydrocarbons and inorganic substances, wherein the water in coal
Dividing is the component being easiest to change.The moisture of coal is the most basic of evaluation Coal Economy value
Index because the change of moisture in coal can cause the content of other component or the change of caloric value,
On the inspection matter of coal, measure, check and accept, management etc. produces certain impact.Coal have a large amount of simultaneously
During moisture, not only the useful component of coal reduces, and large quantity of moisture is when burning, absorbs a large amount of
Heat become steam and evaporated in vain, and make exhaust gas volumn increase, increase flue gas loss
And the energy consumption of exhaust blower, moisture is bigger than ash on the impact of burning according to statistics.The moisture of coal is also
Directly affect the use of coal, transport and store.The moisture of coal increases, and in coal, useful component is relative
Reduce, and moisture becomes steam when burning and to absorb heat, thus reduce the caloric value of coal.Coal
Moisture increase, also add ineffective traffic, and give to unload and bring difficulty.Particularly winter
Cold district, often freezes car, and impact is unloaded, and impact produces, and affects railway carriage turnover, adds
The acute anxiety of transport.The moisture of coal the most easily causes coal to glue storehouse and reduces bunkering capacity, very
To stifled storehouse accident occurs.
Therefore, Accurate Determining moisture in coal is significant to power production management and operation and management.
Traditional full aquametry is all measured in the ature of coal Kinds of Moisture Monitors in laboratory.In order to survey
Determine the content of moisture in coal, need that the weighing botle equipped with coal is put into drying chamber body and be dried, make
Moisture rapid evaporation in coal, but for the extremely sensitive coal of temperature, it is the most oxidized,
Need to be passed through protective gas nitrogen, make protective gas that the air in cavity is extruded, reach
It is the state of protective gas entirely around coal sample, thus prevents it from aoxidizing.Existing logical nitrogen drying chamber
Body mainly has following two form: one is directly on the basis of forced air drying cavity, directly
Access trachea, serve as logical nitrogen and be dried cavity；Another kind is to set in the cavity of forced air drying cavity
Put a built-in box body, box body accesses nitrogen interface, utilizes the heating of forced air drying cavity
Element heats, then passes to, in built-in box body, make cavity by air heated in cavity
Temperature reaches baking temperature.The first logical nitrogen is full of nitrogen in being dried the whole cavity of cavity, works as quilt
Survey coal sample less time, serious waste effective usage amount of nitrogen, add cost.The second
Waste the problem of a large amount of nitrogen although solving because tested coal sample amount is little, but be transferred to built-in
The heat of box body makes indirectly, and box body temperature reaches the time growth of baking temperature, and wave gives
Time and electricity, can increase production cost equally.And above two is dried cavity and all exists not
At any time the coal sample needing detection can be processed, it is necessary to after waiting all of coal sample off-test
Just can carry out the test of fresh sample, must wait last simultaneously when the coal sample of different in moisture content is tested
One coal sample off-test could terminate logical nitrogen and be dried the work of cavity, reduces work efficiency.
