Abstract
The method and apparatus of eliminate air contaminant with powder belong to the field of air purifying technology. The method can change gaseous air contaminant into granular contaminant and eliminate the granular contaminant in a conventional purifying device without resulting in pipeline jamming. The air contaminant eliminating process has proper powder amount selected, properly controlled rotation speed of the fan and powder concentration. The powder and air contaminant react physically and chemically in the mixing reactor, and the treated air contaminant is then eliminated with one dry dedusting device. The present invention has simple process, low cost and other advantages.
Description
Technical field
The present invention relates to a kind of method and apparatus, belong to the air pollutants field of purification with dust processing air pollutants.
Background technology
Air is the important component part of human basic living environment, and the people can not break away from air a moment.Along with social development, the energy, resource consumption increase, and the discharging of air pollutants constantly increases; Simultaneously, people's environmental consciousness strengthens, and is more and more higher to the requirement of environmental quality.
Air pollutants are meant because mankind's activity or the material to people or environment generation adverse effect that natural process directly enters air or new conversion generates in air; Can be divided into two big classes by the form that exists: particulate form pollutant and gaseous contaminant.
Except taking to reduce the technical measures of air pollutant emission, air pollutant purification apparatus be installed be the basis of air quality of controling environment, also be the prerequisite of carrying out every comprehensive preventive health measures such as Environmental Planning and Management.
At the particulate form pollutant, dry cleaning device commonly used and wet purifying decice.Because wet purifying decice can produce waste water, its operating cost is higher relatively, only in the particulate form pollutant place that some dry cleaning devices can not be handled, just can use wet purifying decice.
At gaseous contaminant, technology such as condensation commonly used, burning, absorption, absorption, biological cleaning.Because the air pollution source category is numerous, the gaseous contaminant complicated component, and concentration differs between each composition; Because aforementioned various technology all have its range of application and pluses and minuses, take monotechnics to handle or the operating cost height, or one-time investment are big, is difficult to reach well-content result.
Summary of the invention
Problem at prior art situation and existence, the present invention is intended to propose a kind of method and apparatus of handling air pollutants with dust, realize purifying gaseous contaminant, the particulate form pollutant is carried out primary treatment, reach the air pollutants blocking pipe no longer after the processing, and can be by the purpose of conventional dry cleaning device processing.The property of the present invention is directed to is strong, method is simple, simple to operate, security of operation, cost of investment are low, promotes the use of conveniently.
Technical method of the present invention is as follows with device:
Referring to accompanying drawing, dust generator, two major parts of mixing reactor have been the present invention includes.The dust generator mainly comprises container (8), airborne dust device (6), blower fan (5), control system (7), dust sensor (4); Mixing reactor mainly comprises reaction vessel (2), nozzle (3), supersonic generator (1).
Select the suitable dust of proportioning according to the particulate pollutant in the air pollutants (as: dust, cigarette, flying dust, black smoke, mist, flue dust etc.) and the character of gaseous state pollutant; According to the detection data of dust sensor to air inlet air pollutant concentration and flow velocity, control system is controlled amount and the concentration that enters dust in the mixing reactor by regulating rotation speed of fan.Then by the airborne dust device with dust with mixing with the air pollutants that enter the same period in the blower fan suction mixing reactor; Dust and air pollutants bump in mixing reactor, adhere to, absorption, coalescence, physical-chemical reaction such as condense.
Particulate pollutant is by behind the conversion zone, and it is big that grain diameter becomes, humidity, active and bond performance reduction; Gaseous contaminant is by behind the conversion zone, and the overwhelming majority is adsorbed and chemical conversion, as: poisonous micro-content organism (polycyclic aromatic hydrocarbon etc.), VOC (benzene, toluene etc.) can both be adsorbed by dust.In the conversion zone of mixing reactor supersonic generator is installed, frequency of ultrasonic is to determine according to the character of used dust and air pollutants, its objective is and impel the dust mobility to increase, to promote the physical-chemical reaction between dust and the air pollutants, air pollutants after feasible the processing are blocking pipe no longer, and can be handled by conventional dry cleaning device.
System of parameters such as the character of the dust that the present invention is selected, humidity and particle diameter are according to various parameters decisions such as the character of air pollutants and concentration; The dust of selecting for use is one or more the dust that mixes by different proportion such as potter's clay, kaolin, medical stone, active carbon, zeolite, polymeric adsorbent, vulcanized rubber.And the dust that falls into the dry-type dedusting equipment ash bucket after the processing can be reused; The particle size range of dust guarantees can not produce to the very big live load of dry cleaning device generation at the 30-600 micron.
Description of drawings
Accompanying drawing is the inventive method and schematic representation of apparatus.
The specific embodiment
Referring to accompanying drawing, dust generator, two major parts of mixing reactor have been the present invention includes.The dust generator mainly comprises container (8), airborne dust device (6), blower fan (5), control system (7), dust sensor (4); Mixing reactor mainly comprises reaction vessel (2), nozzle (3), supersonic generator (1).
Select the suitable dust of proportioning according to the character of particulate pollutant in the air pollutants and gaseous state pollutant; According to the detection data of dust sensor (4) to air inlet air pollutant concentration and flow velocity, control system (7) is controlled amount and the concentration that enters dust in the mixing reactor by regulating rotation speed of fan.Then by airborne dust device (6) with dust with mixing with the air pollutants that enter the same period in blower fan (5) the suction mixing reactor; Under action of ultrasonic waves, physical-chemical reaction takes place in dust and air pollutants in mixing reactor, and feasible air pollutants after treatment are blocking pipe no longer, and can be handled by conventional dry cleaning device.
