Description
Technical field
The present invention relates to dust suppression refining plant field, it is specifically related to a kind of wind spraying aid type ultrasonic wave micron order suppressing dust with dry mist system and method.
Background technology
At present, China pneumoconiosis patient gets more and more, and pneumoconiosis has become occupational illness first place, accounts for total occupational illness 76%, and industry is respectively coal, non-ferrous metal and building materials. Wherein coal relevant industries account for again more than 46%, and increase year by year, it is seen that the sanitary condition in dust work place does not obtain basic improvement, and dust is the direct inducement of pneumoconiosis, so dust disposal is extremely urgent.
Dust suppression administer main to as if 150 ��m below dust granules, particularly the sucked dust granules of diameter below 10 ��m, although its in material total amount proportion less than 1%, but it is very big to the injury of the person, being the main contributor causing the occupational illness such as pneumoconiosis, the health and lives of the mankind in serious threat. And in existing dedusting dust suppression technology, the improvement that uncontrollable discharge pollutes less than 10 ��m inhalable dust (PM10) does not have basic governance approach. Present dust removal installation more consideration initial stage drops into and does not consider the operation maintenance cost in later stage, emphatically it is considered that to the improvement of visible dust (person of outstanding talent's rice level), and have ignored the improvement to human body inhalable dust (micron order).
Existing dust removal installation mainly contains following several:
The first, sack cleaner, is mainly extracted in sack cleaner by the mixture of ash and air, by the filteration of cloth bag, by ash and air separation, air enters air by cloth bag is inner through the outlet of negative pressure blower fan, ash, due to the effect of gravity, falls into ash storehouse through blocking valve. There is following shortcoming: (1) cloth bag water-absorbent is big, it is easy to fouling, not antistatic, not fire-retardant, and long term operation air permeability is poor, affects dust removing effects; (2) fly-ash separator produces secondary pollution in deashing process; (3) fly-ash separator is grey clearly unreasonable and section's class hour can not cause energy loss; (4) equipment is easily aging, maintenance cost height, and maintenance load is big, it may also be useful to the life-span is short, and floor space is bigger; (5) when source of pollution disperse, dust is difficult to collect, and when some characteristic dust (as: coal dust) reach finite concentration, will blast in the situation of high temperature, naked light, electrical spark, friction, shock; (6) selecting the characteristic that must consider dusty gas during filtrate, its filtrate of general requirement has the features such as corruption wear-resisting, resistance to, resistance are low, long service life, thus adds the manufacturing expense of filter bag; (7) character of filtrate determines sack cleaner and has limitation relative to dust; 8) regulation effect is poor, although discharge value reaches 50 milligrams/cubic metre of country's permission, but 10 milligrams/cubic metre that pollute that on-the-spot improvement index does not all reach national regulation.
2nd kind, electric precipitator, when mainly dusty gas is by high tension electrostatic field, make grit charged, under the effect of electrical forces, charged grit is made to deposit on circuit board, after dust deposits to certain thickness, shaken by rapping and fall in ash bucket and by ash-valve, ash is drained, thus reached the object of dedusting. There is following shortcoming: (1) once invests height, steel consumption amount is big; (2) electric precipitator requires higher making and installation precision usually, otherwise can not ensure that it runs normally and efficiently; (3) floor space is bigger owing to field gas velocity is lower for electric precipitator; (4) handled dust be there are certain requirements by electric precipitator, the dust beyond optimum range, adopts electric precipitation will have corresponding measure, could ensure necessary dust removal performance.
The third, spraying and dedusting, mainly before belt deflector chute, the position such as section installs water spray system additional, makes the humidity increase of coal reach the object not easily playing dirt. There is following shortcoming: (1) water loss is huge; (2) the calorific value loss of coal is big; (3) coal mud clearing causes the loss of coal and increases coal slime processing cost; (4) regulation effect difference cannot reach the standard of 10 milligrams/cubic metre of national regulation.
4th kind, unpowered dedusting, uses aerodynamic principle, adopts pressure equilibrium and closed loop circulation style, reduces the pressure of blanking bucket class dust air to greatest extent, makes it to tend to balance with external air pressure. Material can produce a large amount of negative-pressure air-flows when falling, and dust, under the guiding of negative-pressure air-flow, moves at enclosed space internal recycle, clashing into pressure plate, translational motion turns into curvilinear motion, reduces the potential energy of self, dirt lowers under gravity, reaches the object of dedusting. There is following shortcoming: (1) investment is big; (2) dust catching rate is low; (3) horizontal pipe easily blocks, and affects capture rate; (4) purification efficiency lower (being generally 40% to 50%); (5) floor space is big.
5th kind, single fluid high pressure dry fog dedusting, through high pressure ceramic plunger pump, pressurizes water through piping, by high-pressure nozzle atomizing, is being connected to dirt point by pipeline, is reaching the object of dedusting. There is following shortcoming: (1) nozzle easily blocks; (2) equipment failure rate height, maintenance cost height; (3) for the dust of sports equipment, the regulation effect playing dirt point can only reach 30% to 40%; (4) due to spray nozzle clogging, pipeline connection is easily quick-fried opens; (5) safety coefficient is low, is, by high-pressure pump, water is pressurized to 6MP-8MP due to equipment, once pipeline explosion or wash open, can field personnel be damaged and on-the-spot equipment causes unnecessary loss; (6) to the requirement height of the purity at water source; (7) strainer easily blocks.
6th kind, two-fluid dry fog dedusting, main utilization high-pressure air source and water source, pipeline and gas-water mixed type nozzle, by an air compressor, air is compressed to gas-holder, then form water smoke through gas-water mixed type nozzle again by tracheae and water pipe, equipment is installed to the object that dirt point reaches dedusting. There is following shortcoming: (1) current consumption is big, tens kilowatts easily, or even several hundred kilowatts; (2) floor space is big, will have special equipment room; (3) equipment more complicated, it is desired to equipment is allocated and transported and installed and maintenance management level height; (4) dust is had certain selectivity, all dust can not be made can to obtain very high purification efficiency; (5) once invest bigger.
Owing to there is above weak point, some heat power plants, harbour, Steel Plant, colliery, chemical plant, defeated coal or conveying system dust removal installation are substantially in and fall into disuse inactive state, part power plant, harbour, colliery etc., after changing several dust removal installation, still do not reach the basic goal for the treatment of flour dust.
