Description
Technical field
The present invention relates to dust technical field of measurement and test more particularly to a kind of dust based on humidity dust concentration modifying factor
Concentration determination method.
Background technology
Dust harzard is one of coal mine Major Natural Disasters.Excessive concentration can cause pneumoconiosis and coal-dust explosion, influence coal
Mine is kept the safety in production.Therefore, dust measuring, it is dust-proof be ensure Safety of Coal Mine Production an important process.Currently, home and abroad colliery is universal
Dust concentration is controlled using the method for wet spray depositing dust, but due to lack science detection with automatically control, cause
There are blindness in practical application, waste great lot of water resources, and coal is made to be lost in mine water as coal slime, coal water, simultaneously
Increase influence of the humidity to production process.
Invention content
In view of the drawbacks described above of the prior art, technical problem to be solved by the invention is to provide one kind being based on humidity powder
The dust concentration test method of dust concentration modifying factor, it is intended to reduce powder concentration measurement error, rationally control atomizing de-dusting
Number, to reduce loss and the work on the spot humidity of coal, this method has scientific and practicability well.
To achieve the above object, the dust concentration test based on humidity dust concentration modifying factor that the present invention provides a kind of
Method, which is characterized in that include the following steps:
Step 1 establishes dust concentration and air humidity relational model, wherein set dust concentration as C, modifying factor Cx, and relatively
Humidity is RH, and it is Co that existing sensor of dust concentration, which measures dust concentration value, defines C and is:C=Co/Cx;
Step 2 is layouted to specified fully-mechanized mining working, and each section that samples takes l0 sampled point;
Step 3 gets out filter membrane, and filter membrane is cut spare by the size of thief hatch;
Step 4, sampler are placed in selected sampled point, are first fitted into sampling head and are screwed with a filter membrane clip equipped with filter membrane,
It starts sampler and is adjusted to required flow, then filter membrane is fitted into sampling head and is screwed, so that filter membrane is met by dirt face distinguished and admirable to dust-laden;
Step 5, calibrating instrument set flow, complete rear setting instrument sample time to be prepared, measure filter membrane weight, dust first
Concentration sensor measures dust concentration value Co and live humidity value RH;
After step 6, sampling, filter membrane is removed from filter membrane clip with tweezers, by dirt towards interior folding, is wrapped, is put with lining paper
Human sample's bag, takes back laboratory and is analyzed.
A kind of above-mentioned dust concentration test method based on humidity dust concentration modifying factor, it is characterised in that:It is described
Modifying factor Cx and the relational expression of ambient humidity RH are:
Cx=1+0.25* { RH3/(1-RH)}.
The beneficial effects of the invention are as follows:
After the modifying factor of the present invention corrects dust concentration, when humidity is less than 65%, concentration is not substantially with the variation of humidity
And change;When humidity is more than 65%, concentration reduces with the increase of humidity;When humidity is more than or equal to 90%, dust concentration
Value is less than or equal to lOmg/m3, need not carry out atomizing de-dusting.Avoid coal as coal slime, coal water and caused by be lost in, subtract simultaneously
Small influence of the humidity to production process, and saved water resource.
Specific implementation mode
A kind of dust concentration test method based on humidity dust concentration modifying factor, which is characterized in that including following step
Suddenly:
Step 1 establishes dust concentration and air humidity relational model, wherein set dust concentration as C, modifying factor Cx, and relatively
Humidity is RH, and it is Co that existing sensor of dust concentration, which measures dust concentration value, defines C and is:C=Co/Cx;
Step 2 is layouted to specified fully-mechanized mining working, and each section that samples takes l0 sampled point;
Step 3 gets out filter membrane, and filter membrane is cut spare by the size of thief hatch;
Step 4, sampler are placed in selected sampled point, are first fitted into sampling head and are screwed with a filter membrane clip equipped with filter membrane,
It starts sampler and is adjusted to required flow, then filter membrane is fitted into sampling head and is screwed, so that filter membrane is met by dirt face distinguished and admirable to dust-laden;
Step 5, calibrating instrument set flow, complete rear setting instrument sample time to be prepared, measure filter membrane weight, dust first
Concentration sensor measures dust concentration value Co and live humidity value RH;
After step 6, sampling, filter membrane is removed from filter membrane clip with tweezers, by dirt towards interior folding, is wrapped, is put with lining paper
Human sample's bag, takes back laboratory and is analyzed.
A kind of above-mentioned dust concentration test method based on humidity dust concentration modifying factor, it is characterised in that:It is described
Modifying factor Cx and the relational expression of ambient humidity RH are:
Cx=1+0.25* { RH3/(1-RH)}.
The humidity RH and concentration situation of change table that the scene of being given below is surveyed:
As it can be seen that dust concentration does not change substantially with the variation of humidity when 1. humidity is less than 65%, but after humidity is more than 65%
Concentration is changed greatly with humidity, and the general trend with the increase concentration of humidity reduces;2. even if when humidity reaches 90%
When, also above lOmg/m3, this means that will spray the dust concentration value Co that conventional method measures according to relevant criterion
Depositing dust has ignored influence of the humidity to concentration, wastes a large amount of water resource.
The modified dust concentration of the present invention and humidity data table is given below:
As it can be seen that 1. passing through amendment of the modifying factor of the present invention to dust concentration, when humidity is less than 65%, concentration is not substantially with wet
The variation of degree and change;2. humidity is more than 65%, concentration reduces with the increase of humidity;3. when humidity is more than or equal to 90%
When, dust concentration value is less than or equal to lOmg/m3, need not carry out atomizing de-dusting.Avoid coal as coal slime, coal water and caused by
It is lost in, while reducing influence of the humidity to production process, and saved water resource.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be in the protection domain being defined in the patent claims.
