Description

A kind of dust suppression system

Technical field

The present invention relates to dust suppression purification device fields, and in particular to a kind of dust suppression system.

Background technique

Currently, China's Pneumoconiosis Patients are more and more, pneumoconiosis has become occupational disease first place, accounts for total occupational disease 76%, row Industry is respectively coal, non-ferrous metal and building materials.Wherein coal relevant industries account for 46% or more again, and increase year by year, it is seen that dust The sanitary condition of Work places does not obtain basic improvement, and dust is the direct inducement of pneumoconiosis, so dust processing is compeled In the eyebrows and eyelashes.

The main object that dust suppression is administered is that 150 μm of dust particles below, especially diameter are below inhalable at 10 μm Dust particles, although for proportion less than 1%, it is very big to the injury of the person, is to cause pneumoconiosis in material total amount for it The main contributor of the occupational diseases such as disease seriously threatens the health and lives of the mankind.And in existing dedusting dust suppression technology, to inorganization The not basic governance approach of the improvement of 10 μm of exhaust emission or less respirable dusts (PM10).Present cleaner is more Consideration initial stage puts into and does not consider the operation maintenance cost in later period, and what is considered emphatically is the improvement to visible dust (bold and unconstrained meter level), And have ignored the improvement to human body respirable dust (micron order).

Existing cleaner mainly include the following types:

The first, the mixture of ash and air is mainly extracted into bag filter, passes through cloth bag by bag filter Filtration, by ash and air separation, air is by being discharged into atmosphere, work of the ash due to gravity through negative-pressure air fan outlet inside cloth bag With falling into Hui Ku through blocking valve.It has the disadvantage in that (1) cloth bag water imbibition is big, is easy fouling, it is not antistatic, it is not fire-retardant, it is long Phase work aeration is poor, influences dust removing effects；(2) deduster generates secondary pollution in deashing process；(3) deduster deashing is not Rationally and not section will cause energy loss in class hour；(4) equipment is easy aging, and maintenance cost is high, and maintenance load is big, service life It is short, and occupied area is larger；(5) when pollution sources disperse, dust is difficult to collect, and works as some characteristic dust (such as: coal dust Dirt) when reaching a certain concentration, will high temperature, open fire, electric spark, friction, hit the case where explode；(6) filtrate is selected When the characteristic of dusty gas must be taken into consideration, generally require its filtrate to have the features such as low wear-resisting, corrosion resistant, resistance, long service life, from And increase the manufacturing expense of filter bag；(7) property of filtrate determines that bag filter has limitation relative to dust；8) it controls Reason effect is poor, although discharge value reaches 50 milligrams/cubic metre of country's permission, state is not achieved in the improvement index at pollution scene 10 milligrams/cubic metre as defined in family.

Second, electric precipitator when mainly dusty gas passes through high-voltage electrostatic field, keeps grit charged, in electric field force It under effect, deposits to charged grit on circuit board, after dust deposit is to certain thickness, is shaken by rapping and fall on ash Ash is drained in bucket and by ash-valve, to achieve the purpose that dedusting.Have the disadvantage in that (1) once investment is high, steel disappear Consumption is big；(2) electric precipitator usually requires that higher manufacture installation accuracy, otherwise it cannot be guaranteed that it normally and efficiently runs；(3) electric Deduster is lower and occupied area is larger due to field gas velocity；(4) electric precipitator there are certain requirements handled dust, suitable Dust other than suitable range, will have corresponding measure using electric precipitation, and just can guarantee necessary dust removal performance.

The third, spraying and dedusting mainly installs water spray system additional in positions such as belt deflector chute leading portions, makes the humidity of coal Increase up to the purpose for being not easy dirt.Have the disadvantage in that (1) water consumption is huge；(2) the calorific value loss of coal is big；(3) coal slime is clear Reason causes the loss of coal and increases coal slime processing cost；(4) regulation effect difference is unable to reach 10 milligrams/cubic metre of national regulation Standard.

4th kind, power-free dust-removing is maximum using pressure balance and closed loop circulation style with aerodynamic principle The pressure of the reduction blanking bucket class dust air of limit, is allowed to tend to balance with external air pressure.Material can be produced when falling Raw a large amount of negative pressure gas flow, dust is under the guidance of negative pressure gas flow, the shuttling movement in confined space, hits pressure plare, straight line Movement becomes curvilinear motion, reduces the potential energy of itself, dirt lowers under gravity, to achieve the purpose that dedusting.In the presence of Following disadvantage: (1) investment is big；(2) dust catching rate is low；(3) horizontal pipe easily blocks, and influences capture rate；(4) purification efficiency compared with Low (usually 40% to 50%)；(5) it takes up a large area.

5th kind, single-fluid high pressure dry fog dedusting pressurizes water through piping, by higfh-tension ceramics plunger pump by height Nozzle atomization is pressed, dirt pits has been connected to by pipeline, to achieve the purpose that dedusting.Have the disadvantage in that (1) nozzle is easy Blocking；(2) equipment failure rate is high, and maintenance cost is high；(3) for the dust of sports equipment, the regulation effect for playing dirt pits can only reach To 30% to 40%；(4) due to spray nozzle clogging, pipe joint is easy to pop；(5) safety coefficient is low, since equipment is Water is pressurized to 6MP-8MP with high-pressure pump, once pipe explosion or washing open, field personnel can be damaged and scene is set It is standby to cause unnecessary loss；(6) requirement to the degree of purity at water source is high；(7) filter is easy blocking.

6th kind, high-pressure air source and water source, pipeline and air water mixing type nozzle are mainly used in two-fluid dry fog dedusting, lead to It crosses an air compressor and air is compressed to air accumulator, then formed by tracheae and water pipe using gas-water mixed type nozzle Equipment is installed to dirt pits and achievees the purpose that dedusting by water mist.Have the disadvantage in that (1) power consumption is big, tens thousand easily Watt, even several hundred kilowatts；(2) it takes up a large area, to there is special equipment room；(3) equipment is more complicated, it is desirable that equipment tune Fortune and installation and maintenance management are horizontal high；(4) there is certain selectivity to dust, cannot make all dust that can obtain very high Purification efficiency；(5) it once invests larger.

Since there is the above shortcoming, some steam power plants, harbour, steel plant, chemical plant coal mine, defeated coal or conveying systems System cleaner, which is substantially at, falls into disuse dead status, and part power plant, harbour, coal mine etc. is after replacement for several times cleaner, still The basic goal for the treatment of flour dust is not achieved.
