Abstract
The utility model discloses a gas-collecting and exhausting gas-curtaining machine making use of gas curtains, mainly comprising gas-curtaining posts, a blower fan, a suction gas hood, a draught fan, etc. The blower fan can supply gas to the gas-curtaining post; the continuous gas curtains can be blew-out according to the same direction of rotation; the gas curtains between the gas-curtaining posts are mutually connected; the circulating gas stream can be generated; a negative-pressure core is formed under the function of the circulating gas stream. One end of the gas-curtaining post is contacted with the suction gas hood; the air entry on the suction gas hood generates the negative-pressure under the function of the draught fan; the harmful gas or powder dust can together flow to the air entry and is discharged under the function of the gas curtain. The gas-curtaining machine can vertically and slantingly exhaust the gas, without being limited by the production conditions or the manufacturing environment. The gas-collecting and exhausting gas-curtaining machine making use of gas curtains is an ideal appliance for exhausting the high temperature fume.
Description
The utility model is a kind of device that harmful gas or dust, flue dust are discharged, and is mainly used in the collection and the discharge of high-temperature flue gas, and is particularly more suitable to the high-temperature flue gas that electric arc furnaces produces.This device is to utilize the mode of air curtain and a kind of gas collection, the dedusting of exhaust, the smoke abatement air curtain machine that constitute.
Pernicious gas of Chan Shenging or dust in process of production, major part utilize dust shield to discharge, because the air-breathing astaticism of dust shield, inspiratory airflow is along with the increase of the distance of leaving air entry, and wind speed weakens and is difficult to pernicious gas or dust are all discharged.In addition except that sucking pernicious gas or dust, simultaneously from around suck a large amount of air, make the load of ventilation blower, pipeline and exhaust gas treatment device all will strengthen, so increased installation cost, so dust shield can only be set near pollution sources.But because the requirement of technological operation and working condition, be difficult in again pollution sources near hood is set, the supply and exhaust dedusting has brought difficulty like this.High-temperature flue gas to producing in producing is too far behind to catch up especially especially.For addressing the above problem, generally adopt the symphyogenetic pressure-vaccum cover of air curtain or jet-stream wind and inspiratory airflow.Air curtain and pressure-vaccum curtain all are the principles of utilizing the stream of emanating, and air nozzle promptly is set around pollution sources, produce the high pressure stream of emanating by the blower fan air feed, and the jet limit directly enters air-suction cover, and pernicious gas or dust are entered in the hood by vertical direction.Because air curtain and pressure-vaccum cover all are the jet current principles that utilizes jet-stream wind, need to produce high pressure draught, and along with the lengthening of distance between nozzle and the air-suction cover, the speed of the stream of emanating is also in decay, so remote exhaust is difficult to realize.
The purpose of this utility model is to utilize the mode of air curtain to seal pollution sources, makes pernicious gas or dust not to external diffusion.By the circulating current of air curtain generation and the negative pressure of air entry, pernicious gas or dust are discharged.In addition, utilize pernicious gas and the dust of circulating current seizure, to be applicable to any working condition and environment away from air entry.
The utility model is achieved in that
Around the pollution sources that will seal, be provided with several air curtain posts, the air curtain post is provided with square air blow-off outlet, air blast is kept watch and is sent in the air curtain post, and the air curtain post blows out continuous wind with certain angle by same direction of rotation to the inside, forms air curtain between the air curtain post that air blows out.Air curtain forms continuous circulating current in the space, one end is provided with air entry at the circulation center, owing to getter action produces negative pressure, the air molecule that this negative pressure core is directly circulating is with centripetal force, and air molecule will be because the turning effort of circulation will produce centrifugal force, in the scope of centripetal force and centrifugal force balance, circulating current forms eddy current, eddy current is brought together around the negative pressure core, towards air entry, so pernicious gas or dust are discharged.
The utility model just utilizes the air blast air-supply, by the air curtain post wind is gone out, and forms air curtain, so equipment is simple; Air curtain produces circulating current and forms eddy current, the air velocity that flows to air entry is not changed, can directly catch the pernicious gas away from air entry, air curtain has cooling effect to high-temperature flue gas simultaneously, need not set up cooling device, can directly flue gas be entered treating apparatus.In addition, the vertically exhaust of air curtain machine, also tiltable exhaust is not limited by equipment and working condition can, and adaptability is strong.Because the air curtain facility have directionality, and pernicious gas and dust can all be discharged.Capacity is reduced, can miniaturization to exhaust gas treatment device or dust collect plant, thereby save cost of equipment, exhaust efficiency height, small investment, economic benefit and obvious environment benefit.
Concrete structure of the present utility model is drawn by following embodiment and accompanying drawing.
Accompanying drawing 1 is the overall structure schematic diagram of air curtain machine;
Accompanying drawing 2 is the structural representation of air curtain post.
From shown in Figure 1, air curtain machine of the present utility model is made up of air curtain post 1, air blast 2, air-suction cover 3, air entry 4, discharge duct 5 and air-introduced machine 6, several air curtain posts 1 keep at a certain distance away be distributed in pollution sources around, form the space that to seal, one end of air curtain post is an air-suction cover 3, the center of air-suction cover 3 is provided with air entry 4, and air entry 4 is connected with discharge duct 5, and air-introduced machine 6 is housed on the discharge duct.Air curtain post 1 is provided with the air blow-off outlet 7 of square as can be seen from Figure 2, the overall structure of blow-off outlet 7 is a harmonica-type, the aperture opening ratio of blow-off outlet, decide according to required air curtain amount, the length of air curtain post and quantity are not fixed according to the distance of pernicious gas generation spacing air-suction cover and the area in generation source, be generally the 4-10 root, discharge duct 5 can be obliquely installed on the top of air-suction cover 3, and the angle of inclination is between 30 °-90 °.
In specific implementation process, air curtain post 1 blows out continuous air curtain with the angle of 10-30 degree by same direction of rotation by air blast 2 to the inside by airduct, air curtain between the air curtain post interconnects, just produce circulating current, because the sucking action of circulating current forms the negative pressure core, under the effect of air-introduced machine 6, air entry 4 places produce negative pressure, so the air curtain of rotation makes pernicious gas or dust together flow to air entry 4, enters gas purifying equipment by discharge duct 5, discharging after purifying.This vertically exhaust of air curtain machine, also tiltable exhaust, the angle of inclination can be controlled between the 30-90 degree, its exhaust efficiency still can reach more than 99%, for pernicious gas and the dust of collecting the point source uncontrollable discharge, be desirable effective equipment, the collection of the high-temperature flue gas that electric arc furnaces is produced and discharge more suitable especially.
