Abstract
The utility model relates to a gas curtain type fume catcher which is suitable for being used for guiding and catching the harmful gases containing dust, poison, etc. produced by various pollution sources in the industry. The utility model has the technical proposal that a gap which is arranged on the wall of a jetting tube is used as a nozzle of which the cross section form a shrinking expanding shape; a blower fan is connected with the jetting tube; the high speed gas flow in a single direction jetted to a pollution source from the nozzle form a wind curtain. The jetting tube is arranged near to a fume collecting pipeline, and the jetting tube and the fume collecting pipeline are both arranged on one side of the pollution source. An exhaust fan is arranged on the fume collecting pipeline. The utility model can effectively isolate, seal and catch the harmful fume with small jetting power consumption and high catching rate under the condition that people and objects can pass through a production site with no influence.
Description
The utility model relates to a kind of device that prevents that flue gas from escaping from pollution sources, and this device is specially adapted to industrial guiding, captures pernicious gases such as the dust-laden of all kinds of pollution sources generations, poison.
At present, the pernicious gas that in the industrial production all kinds of pollution sources is produced is at first collected by gas skirt, enters purification facility then and handles, again discharging or utilization.Traditional gas skirt adopts solid covers such as box, umbellate form, Totally-enclosed-type.Adopt the Totally-enclosed-type gas skirt, for handling large-scale, super-huge pollution sources, investment is big, cost is high, and too big owing to taking up space, and brings very big inconvenience for people, thing operation in the production site.The solid cover of other type is because of can not be with the same air insulated of flue gas, and guidance quality is poor, thereby capture rate is low, a large amount of in addition sneaking into of air and increased power consumption greatly.Both made and be furnished with purification facility efficiently, can not reach its intended purposes.Almost powerless for the place that uncontrollable discharge flue gas and people, thing are walked.
In recent years, people begin to explore by the air curtain gas collection and solve this difficult problem in the trapping technique.What adopt as Chinese patent CN " 89201031 " is the harmonica-type nozzle, multicolumn shape air curtain.Many air curtain posts of this device are perpendicular to ground, and the air communication of the harmonica-type nozzle ejection on every air curtain post is crossed the tangential direction of another root air curtain post and formed polygon prism type sealing air curtain.There is following shortcoming in this gas collecting apparatus:
1, every air curtain post is arranged vertically in pollution sources space on every side, so influence walking of people, thing to a certain extent.
2, the gas collecting apparatus of this structure is only limited to facade and vertically uses, thereby all certain limitation of its applied field.
3, be covered with nozzle on every air curtain post, and the intensity of air curtain is directly proportional with the size of air quantity, thereby it is big to have determined the resistance of air curtain to decrease, the power consumption height.
The utility model purpose is to overcome above-mentioned weak point of the prior art and a kind of flue gas of can isolating effectively, seal and collect is provided, and the while does not influence the people again, the little air-curtain type flue gas trapping device of power consumption is walked, sprayed to thing.
The utility model purpose is achieved by the following technical solution: along the parallel direction of playpipe axis, tube wall is provided with the slit as nozzle, the nozzle cross section is the shrinkage expansion shape, air blast connects with playpipe, air is under the effect of air blast, spray unidirectional high velocity air from nozzle to the dirt source, form air curtain.For saving the space, reduce system's draft loss, the flue gas collection conduit arranges that near playpipe the two is equipped with air exhauster with a side that places pollution sources on the flue gas collection conduit.
Can be according to the diffusion characteristics of pollution sources in producing, playpipe is made ring-type, polygonal, straight type etc., thereby can constitute the air curtain of multiple shapes such as column type, umbellate form, plane.
It is big to the utlity model has air curtain intensity, and it is little to spray power consumption, saves advantages such as space, do not influence the people, thing navigates within the prerequisite of production site, can isolate, seal effectively and capture flue gas, the capture rate of raising pernicious gas.
Below with reference to accompanying drawings, further specify the utility model by embodiment.
Embodiment one: the utility model is used to capture the steelmaking converter secondary flue gas.
Annular spray pipe (1) level is placed the lower edge of solid petticoat pipe (4), be fixed on the platform (5).The slit that has the cross section and be the shrinkage expansion shape on the tube wall of annular spray pipe (1) is as nozzle (2), and the length of contraction section is greater than the length of expansion segment, and the contraction section angle of nozzle is 30 °-90 °, and the expansion segment angle is 30 °-90 °.Air blast connects with playpipe (1), air is under the effect of air blast, from the annulus---and nozzle (2) ejection one-way air stream constitutes umbrella air curtain cover, thereby converter is closed at the flue gas that adds link uncontrollable discharges such as steel scrap, hot metal charging, tapping, reduces sneaking into of air.On the other hand, because the air curtain air velocity changes, cause the pressure reduction of local environment, thereby cause air flow direction flue gas collection conduit direction.Go up in flue gas collection conduit (3) under the draft effect of air exhauster, form negative pressuren zone near the solid petticoat pipe (4), the direction of the flue gas flow direction solid petticoat pipe (4) in the air curtain cover enters flue gas collection conduit (3).Above the gas flow of the interior bottom of air curtain cover, the outer air of cover enters from the air curtain bottom and covers interior replenishing, and to keep the interior upper and lower part of cover and to cover inside and outside dynamic equilibrium, has so just avoided secondary flue gas to escape.
Embodiment two: the utility model is used to capture the pernicious gas of uncontrollable discharge.
Establish flue gas collection conduit (3) in a side of pollution sources, the porch of flue gas collection conduit is provided with solid gas skirt (4).Playpipe (1) is parallel to ground, top near flue gas collection conduit (3) is arranged, can constitute the plane air curtain cover that is parallel to ground from the one-way gas flow of nozzle (2) ejection, so that the pernicious gas that pollution sources are produced is limited in this below height, simultaneously, highly pernicious gas and outside air are separated from this, and it is directed in the flue gas collection conduit (3) by solid gas skirt (4).Under the effect of air curtain, outside air can only (air velocity of nozzle (2) ejection is 0) enter the air curtain inboard from the edge of air curtain, thereby has controlled the diffusion of pernicious gas, also reduced the mixed volume of outside air, reduce environmental pollution.
Claims (4)
1, a kind of air-curtain type flue gas trapping device with playpipe (1), nozzle (2), air blast, flue gas collection conduit (3), air exhauster, air blast connects with playpipe (1), air exhauster connects with flue gas collection conduit (3), along the parallel direction of playpipe (1) axis, tube wall is provided with the slit as nozzle (2), it is characterized in that the nozzle cross section is the shrinkage expansion shape, playpipe (1) arranges that near flue gas collection conduit (3) the two is with a side that places pollution sources.
2, the air-curtain type flue gas trapping device according to claim 1 is characterized in that said nozzle contraction section length is greater than expansion segment length.
3, according to claim 1 or 2 described air-curtain type flue gas trapping devices, the contraction section angle that it is characterized in that nozzle is 30 °-90 °, and the expansion segment angle is 30 °-90 °.
4, according to claim 1 or 2 described air-curtain type flue gas trapping devices, it is characterized in that the porch of said flue gas collection conduit (3) is provided with solid gas skirt (4).
