The present invention particularly, relates to a kind of open-air dust-removal system.
Background technology
The air that nature is pure and fresh, clean, makes people relaxed and joyful, in high spirits.But along with developing rapidly and population sharp increase of industry, the chemical substance that a large amount of burning coal, oil produce is discharged in air with the form such as waste gas and flue dust, exceed the tolerance of atmospheric environment, to the life of the mankind, production with healthyly bring harm.As London dense fog on December 5 ~ 8 nineteen fifty-two be for burn coal the flue dust that produces and smog do not distribute not go out, cause ten million human respiratory to infect, in 4 days, death reaches people more than 4000.The industrial waste gas that Japanese Yokkaichi petroleum refinings in 1991 and industrial fuel oil discharge, causes whole city's asthmatic attacks.
At field of Environment Protection, along with environmental pollution worsens, corresponding deduster produces successively, and current deduster can be divided into two large classes:
(1) dry collector: comprise gravity settling chamber, inertial dust separator, electric cleaner, sack cleaner, cyclone dust collectors.
(2) wet scrubber: comprise spray column, impingement dust collector, Venturi scrubber, bubble dust collector and water dust scrubber.
But there is very large drawback in above deduster in the air pollution of improvement open-air atmosphere, first, apparatus arrangement is loaded down with trivial details, expends the energy comparatively large, and the problems such as high-voltage corona obturation and high voltage electrical isolation easily go to pot may appear in electrostatic precipitator process high concentrate dust; Secondly, the automatic control of complete equipment cannot be realized according to external environment, cause the problems such as the low and product shortening in service life of equipment efficiency of dust collection.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of open-air dust-removal system, to realize energy-saving safe carries out dedusting efficiently advantage according to external environment.
For achieving the above object, the technical solution used in the present invention is:
A kind of open-air dust-removal system, comprise high bar sprayer unit, charged demist dust arrester, sensor of dust concentration, air humidity sensor, anemobiagraph, controller and automatic telescopic dust collection plate, described sensor of dust concentration, the Signal transmissions that air humidity sensor and anemobiagraph gather is to controller, this controller calculates the dust concentration of air this moment according to the data received, air humidity and extraneous wind speed, described controller is according to the dust concentration of the air calculated, air humidity and extraneous wind speed, control the spray amount of high bar spraying, spray angle and charged demist dust arrester, and control the expansion or closed of automatic telescopic dust collection plate.
Further, described high bar sprayer unit can make water fogging as diameter is at the water fog particle of 1 ~ 10 micron, and this water fog particle aerial dust that will suspend is coalescent agglomerating.
Further, described water fog particle to adsorb and coalescent agglomerating at the respirable dust particle of 1 ~ 10 micron diameter.
Further, described charged demist dust arrester can produce high voltage electric field, when fog, dust granules are charged by producing during high voltage electric field, fog after charged and dust are at the move under influence of electric field force, be deposited on dust collection plate, and be collected, prevent secondary dust, inhibit fog ascension and dust from flying.
Further, described automatic telescopic dust collection plate according to wind-force size Automatic-expanding or can close, and causes damage when preventing wind-force larger to equipment.
Technical scheme of the present invention has following beneficial effect:
Technical scheme of the present invention, detected by the environment of various sensor to surrounding, and detection data are transferred to controller, the environmental data that controller detects according to each sensor, control spray amount, the spray angle of the spraying of high bar, adjust charged demist dust arrester electric field relevant parameter and control the action of automatic telescopic dust collection plate.To realize the Self Adaptive Control of this open-air dust-removal system environmental modulation to external world, reach best dust removing effects and minimum water yield loss, and its intelligentized design industry decreases the cost of labor of dust pelletizing system, thus achieve safe and efficient energy-conservation according to the adaptive dedusting object of external environment.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Accompanying drawing explanation
The principle frame that Fig. 1 is the open-air dust-removal system described in the embodiment of the present invention;
Fig. 2 is the electronic circuitry of the open-air dust-removal system amplifying circuit described in the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of open-air dust-removal system, comprise high bar sprayer unit, charged demist dust arrester, sensor of dust concentration, air humidity sensor, anemobiagraph, controller and automatic telescopic dust collection plate, sensor of dust concentration, the Signal transmissions that air humidity sensor and anemobiagraph gather is to controller, this controller calculates the dust concentration of air this moment according to the data received, air humidity and extraneous wind speed, controller is according to the dust concentration of the air calculated, air humidity and extraneous wind speed, control high bar sprayer unit and charged demist dust arrester, and control the expansion or closed of automatic telescopic dust collection plate.Major control height bar spraying spray amount, spray angle and adjust charged demist dust arrester electric field relevant parameter.To realize the Self Adaptive Control of this open-air dust-removal system environmental modulation to external world, reach best dust removing effects and minimum water yield loss.
Wherein, high bar sprayer unit can make water fogging as diameter is at the water fog particle of 1 ~ 10 micron, and this water fog particle aerial dust that will suspend is coalescent agglomerating.Can be coalescent agglomerating by dust close with it for the aerial diameter that suspends, effectively reduce the concentration of PM2.5 and PM10 in air.
Water fog particle to adsorb and coalescent agglomerating at the respirable dust particle of 1 ~ 10 micron diameter.
