Definitions
- the invention relates to a method for minimizing nitrous gases in underground mining and tunneling, which are contained in the blasting of the shots with a stocking of conventional gelatinous explosives in mining and also as emissions of diesel engines in the
- the invention also relates to a system for maintaining the maximum workplace concentration with respect to nitrous gases in the
- MAK Occupational Exposure Limit
- emulsion explosive which does not release such No x gases.
- the emulsion explosive used for this purpose is more expensive than the usual gelatinous explosive and, moreover, releases ammonia, which is also to be considered a negative side effect.
- the removal of the workforce from the respective explosive area until the nitrous gases are diluted to such an extent that the MAK value is reached again is the usual today
- the invention has for its object to reduce the costs incurred in explosive swaths in underground mining and tunneling and possibly in diesel emissions No x - on the legally valid limit (MAK value) and below.
- Diesel units emitted or released a larger amount of diesel emissions. Again, these emissions are absorbed and then the same
- the explosive swaths of suspended particulate matter and No x components are separated and then fed back to the ventilation via the downstream fan. As already explained above, it is therefore no longer necessary to load these originally with the No x components
- Components can be removed from the weather, so that these weather components then easily in the total weather flow
- An installation for carrying out the method provides that on
- a deduster and a vacuum generator are arranged, between both a No x separator is connected, which is preferably designed with respect to the degree of separation of pollutants adjustable.
- the invention also teaches with respect. The required for carrying out the process plant clear that the explosive swaths and / or the
- Vacuum generator are collected to be then cleaned in a arranged between two No x -Abscheider.
- the No x -Abborger is designed to be adjustable, so adjust to the amount of dust or No x components can let. It is important that the resulting emissions, ie above all the explosive swaths, are sucked in via a correspondingly strong vacuum generator, in order then to be cleaned in the deduster with respect to the suspended solids and then to be sucked through with the necessary negative pressure through the No x separator. then completely cleaned in the
- the dust extractor is assigned an adjustable or movable nozzle of a Luttentour.
- This adjustable nozzle can be made sure that in particular the diesel emissions are targeted sucked off directly at the place of origin, ie on the diesel engine, regardless of where this diesel engine is currently.
- this adjustable training of the Luttentour or the Luttentourendes actually not so important, but also has advantages, especially because these blasting waves move along the ridge along the track and so an accurate
- the deduster is designed as a particulate matter dust filter, so a dry filter over which the suspended solids safely and almost completely from the
- the No x - separator is designed as activated carbon packed bed filter, which can also be used with perlites or with active coke bed filters used.
- activated carbon it is certain that the No x ingredients are bound and held, and then disposed of with the activated carbon together. This ensures that behind the No x separator a diesel and diesel
- the No x -Abscheider is designed as a wet scrubber with or without additive tank.
- the wet scrubber can be fed with auxiliaries, which facilitate or secure the No x -Abscheidung. It is quite conceivable, the wet scrubber between the actual deduster and a
- the compact housing consists of stable and transportable individual housings which are designed to be coupled to one another so that these individual housings can be transported separately as required, but then be reconnected to each other without major problems at the new location.
- the individual parts of the system if necessary, different from each other, ie, for example, a single housing with a wet scrubber between so switch that a quasi double No x -Abborgung is possible.
- the invention is characterized in particular by the fact that a method and a plant are created, with which it is possible to clean nitrous gases in underground mining and tunneling so that the weather can be returned without risk again in the normal weather.
- Figure 1 a system for cleaning No x containing bettors
- Figure 2 a housed plant.
- Appendix 1 illustrates that it should be cleaned via a dust extractor 3 and a vacuum generator 4 in the form of a simple fan No x containing weather or blasting swaths.
- the vacuum generator 4 ensures that the weather on the Luttentour 8 and a movable nozzle 7 are first sucked into the dust extractor 3.
- the dry dedusting ie the
- this activated carbon bed bed filter 10 or the No x separator 5 can be supplemented by a wet scrubber 11 with an additive tank 12, or the wet scrubber 11 takes over the function of the activated carbon bed filter 10.
- the weathers purified in this way then return to the vacuum generator 4 usual weather current.
- the No x separator 5 can either be an activated charcoal bed filter 10 or a wet scrubber 11, but that it is also possible to contain the No x- containing
- Components or weather first pass through the wet scrubber 11, then make an aftertreatment in activated carbon bed filter 10.
- Figure 2 illustrates that the system 1 is housed in a compact housing 15 so as to meet the specific requirements of underground mining.
- This stable compact housing 15 allows the transport of the entire system from one application area to another, this
- Compact housing 15 expediently consists of a plurality of individual housings 16, 17, 18, which can be coupled together to transport them individually, but easy to connect again. They therefore have corresponding stops 20, 20 '. All mentioned features, including the drawings to be taken alone, are considered to be essential to the invention alone and in combination.
