At present, electric precipitation, bag-type dusting and wet dust removal etc. are generally used in dedusting, and these devices are each defectiveness also.Electric precipitation is prone to airborne dust, and vibration dust-cleaning easily makes deduster go wrong, and some particle is subjected to resistivity effects own and filter efficiency is not high.Bag-type dusting is not suitable for caking property particle filtering and hygroscopicity dust-filtering.The wet dust removal water consumption is larger, and is undesirable to granule particle diameter filter efficiency.

The utility model content

The utility model discloses a kind of electrostatic spray dust pelletizing system, can effectively 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 utility model can guarantee that the particle diameter dusty gas has good efficiency of dust collection on a large scale, not only avoids airborne dust, water consumption little, and the small particle less than PM2.5 is also had higher filter efficiency.

Technical solutions of the utility model are achieved in that

A kind of electrostatic spray dust pelletizing system comprises housing, by import to outlet air distributor is installed successively in the housing, electrostatic atomizer filters control of dust wash mill and dehydrator, and housing one end is set to the dust pelletizing system import, the other end is set to the dust pelletizing system outlet, it is characterized in that:

A) described electrostatic atomizer: be connected with at least one atomizer on the feed pipe, atomizer supplies water and is introduced outside system by feed pipe, in each atomizer the place ahead a high-pressure electrostatic ring is arranged, the high-pressure electrostatic ring is connected with the HV generator of system outside by wire;

B) described filtration control of dust wash mill: filter in the control of dust wash mill filler is set, the filler top arranges the trickle distributor, and the trickle distributor is connected with the feed pipe of the outside introducing of system; The filler bottom is connected with earth connection, and water-collecting tray is arranged at the filler bottom, 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 the shower nozzle injection flow rate is adjustable, and electrostatic potential is adjustable between 10-50kV.

The distance that 400-1000mm is arranged between described electrostatic atomizer and the filtration control of dust wash mill.

Filter control of dust wash mill trickle and evenly be sprayed on the filler according to Action of Gravity Field, dust-contained airflow is captured by water and filler.

The utility model dust pelletizing system can be used for the air cleaning of the aspects such as high temperature fume dust removal, the dedusting particle size range is wide, owing to electrostatic atomizer being arranged and filters the control of dust wash mill, by changing the spray amount of high-pressure electrostatic voltage and high-pressure atomization shower nozzle, satisfy the dedusting requirement of dissimilar particle, native system is not only high to the following particles filter efficiency of 50 μ m, and the superfine granule of 0.1 μ m is also had higher filter efficiency.This system has overcome the little problem of some dust specific resistance in the general electrostatic precipitation, and system's automatic pollutant removal that can be in operation can move dedusting continuously.
