Description

A kind of electrostatic spray dust pelletizing system
Technical field
The present invention relates to a kind of electrostatic spray dust pelletizing system, relate to air cleaning and filtering and cleaning technique field.
Background technology
Domestic at present, airborne particulate pollutes and day by day causes people to pay close attention to, and also causes country to pay attention to, while bulky grain particle diameter dust removal requirement, the particles thing of PM10, PM2.5 size is in a lot of local introducing Air Quality Evaluation scope, and granule particle diameter filtering requirement is also improving day by day.Epidemiological study shows, crowd's M & M and Atmospheric particulates (PM) concentration exist significant positive correlation.This correlation shows, migration outdoor enters indoor particle has significant impact to health.The a large amount of poisonous and harmful substance of air PM2.5 adsorption is to the health hazard of human body very large.The fine particle of less than 2.5 μm is then not easily stopped, directly can enter bronchus after being inhaled into human body, causes the disease comprising the aspects such as asthma, bronchitis and cardiovascular disease.These particles can also enter blood by bronchus and alveolar, and pernicious gas wherein, heavy metal etc. dissolve in blood, larger to the injury of health.
At present, dedusting generally uses electric precipitation, bag-type dusting and wet dust removal etc., and these devices are each defectiveness also.Easily there is airborne dust in electric precipitation, vibration dust-cleaning easily makes deduster go wrong, and filter efficiency is not high by resistivity effects own for some particle.Bag-type dusting is not suitable for caking property particle filtering and hygroscopicity dust-filtering.Wet dust removal water consumption is comparatively large, undesirable to granule particle diameter filter efficiency.
Summary of the invention
The invention discloses a kind of electrostatic spray dust pelletizing system, effectively can overcome easy airborne dust, the large filter efficiency of wet dust removal water consumption that existing electric precipitation exists low, especially to drawbacks such as granule particle diameter filter efficiency are poorer.The present invention can ensure that particle diameter dusty gas has good efficiency of dust collection on a large scale, not only avoids airborne dust, water consumption little, and also has higher filter efficiency to the small particle being less than PM2.5.
Technical solution of the present invention is achieved in that
A kind of electrostatic spray dust pelletizing system, comprises housing, is provided with air distributor successively in housing by import to outlet, electrostatic atomizer, filter control of dust wash mill and dehydrator, shell one end is set to dust pelletizing system import, the other end is set to dust pelletizing system outlet, it is characterized in that:
A) described electrostatic atomizer: feed pipe is connected with at least one atomizer, atomizer supplies water and is introduced from system by feed pipe, have a high-pressure electrostatic ring in each atomizer front, high-pressure electrostatic ring is connected with the HV generator of its exterior by wire;
B) described filtration control of dust wash mill: filter in control of dust wash mill and arrange filler, arrange trickle distributor above filler, the feed pipe that trickle distributor is introduced with its exterior is connected; Filler bottom is connected with earth connection, has water-collecting tray bottom filler, and water-collecting tray is provided with tapping pipe.
Described air distributor is a kind of airflow-distribution board, comprises orifice plate and shutter type distribution grid.
Described high-pressure electrostatic ring and atomizer spacing are between 10-30mm, and shower nozzle injection flow rate is adjustable, and electrostatic potential is adjustable between 10-50kV.
The distance of 400-1000mm is had between described electrostatic atomizer and filtration control of dust wash mill.
Filter control of dust wash mill trickle to be evenly sprayed on filler according to Action of Gravity Field, dust-contained airflow is trapped by water and filler.
Dust pelletizing system of the present invention can be used for the air cleaning of the aspects such as high temperature fume dust removal, dedusting particle size range is wide, owing to having electrostatic atomizer and filtering control of dust wash mill, by changing the spray amount of high-pressure electrostatic voltage and high-pressure atomization shower nozzle, meet the dust removal requirement of dissimilar particle, native system is not only high to less than 50 μm particles filter efficiencies, and also has higher filter efficiency to the superfine granule of 0.1 μm.This system overcomes the problem that in general electrostatic precipitation, some dust specific resistance is little, system can be in operation automatic pollutant removal, and dedusting can be run continuously.
