Description
Technical field
The utility model relates to a kind of dust arrester; Specifically it relates to a kind of eddy flow curtain device for reducing dust that is made up of water tank, water pump, water pipe line, control valve, filter, nozzle etc., is applicable to the particularly improvement of respirable dust of the open dust of industrial and mining enterprises.
Background technology
Dust pollution is a stubborn problem in the industrial operations environmental pollution always.According to statistics at present in the world 70% pneumoconiosis patients in China.By 2009, China had about more than 60 ten thousand people of pneumoconiosis patient, by 40,000 yuan of calculating of the annual cost of every example, and more than 240 hundred million yuan of the annual therefore direct economic losses in the whole nation.In addition, the annual newly-increased pneumoconiosis case in the whole nation causes new economic loss also in the speed increment with 600,000,000 yuan of every year, brings heavy financial burden for labourer, employing unit and country.In addition, estimate roughly according to the parties concerned that the direct economic loss that China causes because of occupational disease, industrial accident every year reaches 1,000 hundred million yuan approximately, indirect economic loss reaches 2,000 hundred million yuan approximately.
For the improvement of dust pollution, mainly realize through collecting or adopting limited means to reduce airborne solid grain contamination content.But,,,, become very complicated owing to receive the restriction of environmental factor like the pollution control of open respirable dust for some special dust.Open dust is very big to human harm, and particularly wherein fine dust causes pneumoconiosis easily.And owing to can't airtightly gather dust in this open dirt source; Dust such as the stock ground is removed; No matter is the difficult point that industrial dust is administered, be isolation and the capture from dust always, or the tissue of air-flow and control; Perfect theory and method are not arranged so far as yet, and international and domestic case study is also rare.
Improvement for this type of dust all is to adopt bag-type dusting, electrostatic precipitation and watering dedusting etc. mostly at present.Because characteristics such as this open dirt origin system Dust Capacity are big, diffusion is wide, the efficiency of dust collection of above-mentioned dust collection method is not high always.Therefore, studying a kind of economy, the easy high new technology of efficiency of dust collection, all is very significant to improving the operating space environment with protection employee occupational health.Wet dust collection technology (water mist dust fall technology) meets this thinking.
At present, the wet type depositing dust is to use plain nozzle to carry out water mist dust fall the most widely, yet; Because hydraulic pressure is lower; Seriously influence the atomizing de-dusting effect, total dust depositing dust efficient of this method is merely 50%～60%, and the depositing dust efficient of respirable dust is had only 20%～30%.For addressing the above problem, improve dust-laying effect, device for reducing dust such as ultrasonic atomization spraying, magnetic water spray, preparatory electrostatic charged spray, foam dust-removing, high-pressure fog have appearred on the market.The contact-making surface that these dust arresters have that atomizing effect is good, water consumption is low, droplet density is big, increased spray film and grit, improved the advantage of water smoke individual particle to the arresting efficiency of respirable dust.But efficiency of dust collection is still lower, and droplet diminishes and is subject to the ambient airflow influence, and the life-span is also short, makes water smoke drift with the wind, can not fully arrive to produce the dirt district.
Summary of the invention
The purpose of the utility model is exactly the problems referred to above that exist in the existing spray for dust suppression technique device, has that efficiency of dust collection height, energy consumption are low, wind-engaging is to influence, working service letter and provide a kind of
Just, the open dirt source eddy flow curtain device for reducing dust that is fit to open dirt source depositing dust.This device can form sealing water smoke cover, has the effect of enclosed hood, can effectively control the diffusion of dust, prevents the dust escape.
For achieving the above object, the open dirt of the utility model source eddy flow curtain device for reducing dust adopts following technical scheme:
The open dirt of the utility model source eddy flow curtain device for reducing dust is connected and composed through water pipe line by water tank, water pump, control valve, filter, Pressure gauge and eddy flow curtain humidifier; The outlet pipeline of water pump is provided with the water return pipeline that is used for regulating pondage; Be characterized in: described eddy flow curtain humidifier is linked in sequence by spray boom support, spray boom and nozzle and forms; On described spray boom support, be symmetrically fixed with four spray booms; Every spray boom is provided with plurality of nozzles, and the nozzle bore of the nozzle on every spray boom points to adjacent spray boom in proper order.
It is good that described nozzle adopts rotational pressure formula nozzle.
Described filter adopts y-type filter to be advisable.
Described spray boom support is " worker " font.
The operation principle of the open dirt of the utility model source eddy flow curtain device for reducing dust is: have the nozzle of a row along four different directions of counterclockwise or the mutual vertical distribution of clockwise direction on the setting spray boom of four symmetric arrangement respectively; The pyramid type water smoke cover (spraying curtain) that the water smoke that gushes out from these nozzles seals along four different directions formation one; It is shrouded around the dirt source; Control the diffusion and the escape of dust effectively, thereby caught dust, reached the purpose of depositing dust.Equipment such as flowmeter are formed by connecting through water pipe, and the clean water of different pressures can be provided for nozzle through the by-pass valve control of water pump and control valve.Water is extracted out from water tank by water pump, filters through filter, gets into nozzle through flowmeter, by control valve control flow, obtains needed value.
After the open dirt of the utility model source eddy flow curtain device for reducing dust adopts technique scheme, have the following advantages:
1. adopt booster pump and rotational pressure formula nozzle, make water smoke far firing range, atomizing effect good;
2. system forms the effect that sealing water smoke cover has enclosed hood, can effectively control the diffusion of dust, prevents to escape;
3. outstanding feature is exactly this device owing to formed the eddy flow curtain of a sealing, therefore basically not wind-engaging to influence, having wind and calm situation that open respirable dust is all had higher efficiency of dust collection;
4. dust removal performance is excellent, and resistance is low, administers open post dust efficient and is higher than 95%, can be widely used in the open treating flour dust of each industrial circle, is a kind of desirable update technical equipment.
