Description
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 causes that day by day people pay close attention to, and causes that also country payes attention to, when the dedusting of bulky grain particle diameter requires; The particle diameter particle of PM10, PM2.5 size is in a lot of local air quality ranges of value of introducing, and the granule particle diameter filters and requires also improving day by day.Epidemiological study shows that there is significant positive correlation in crowd's M & M and Atmospheric particulates (PM) concentration.This correlation shows that the particle in outdoor migration inlet chamber has significant impact to health.Atmosphere PM2.5 surface adsorption a large amount of poisonous and harmful substances, very big to the health hazard of human body.2.5 the fine particle below the μ m then is difficult for being stopped, can directly get into bronchus after being inhaled into human body, causes the disease that comprises aspects such as asthma, bronchitis and cardiovascular disease.These particles can also get into blood through bronchus and alveolar, and pernicious gas wherein, heavy metal etc. are dissolved in the blood, and be bigger to the injury of health.
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 makes deduster go wrong easily, and some particle receives resistivity effects own and filter efficiency is not high.Bag-type dusting is not suitable for the caking property particle and filters and the hygroscopicity dust-filtering.The wet dust removal water consumption is bigger, and is undesirable to granule particle diameter filter efficiency.
Summary of the invention
The invention discloses a kind of electrostatic spray dust pelletizing system, it is low effectively to overcome easy airborne dust, wet dust removal water consumption big filter efficient that existing electric precipitation exists, especially to drawbacks such as granule particle diameter filter efficiency are poorer.The present invention 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 high filtration efficiency.
Technical scheme of the present invention is 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) said 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 through the HV generator of lead and system outside;
B) said filtration control of dust wash mill: filter in the control of dust wash mill filler is set, the filler top is provided with 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.
Said air distributor is a kind of airflow-distribution board, comprises orifice plate and blinds type distribution grid.
Said 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 said electrostatic atomizer and the filtration control of dust wash mill.
Filter control of dust wash mill trickle and be sprayed on the filler, dust-contained airflow is captured by water and filler according to the gravity even action.
Dust pelletizing system of the present invention can be used for the air cleaning of aspects such as high temperature fume dust removal; The dedusting particle size range is wide; Owing to electrostatic atomizer is arranged and filters the control of dust wash mill,, satisfy the dedusting requirement of dissimilar particles through changing the spray amount of high-pressure electrostatic voltage and high-pressure atomization shower nozzle; Native system is not only high to the following particle diameter particle of 50 μ m filter efficiency, and the superfine granule of 0.1 μ m is also had high filtration 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.
