Description
Technical field:
The utility model relates to a kind of powder flue dust discharger, particularly relates to a kind of fluid region of no pressure biasing powder smoke shielding and separates discharger.
Background technology:
Along with human civilization advance, people have proposed more and more higher requirement to production, the living environment quality around self.Corresponding, existing powder smoke contamination source, the basic powder flue dust discharger that just is not provided with that has; Though what have is equipped with corresponding powder flue dust discharger, yet because existing apparatus in principle and even technical many disadvantages, can not satisfy the requirement of people to the productive life environmental quality far away, the powder smoke contamination has endangered people's health.
In daily kitchen range, smoke exhaust field, the shielding of oil smoke, separation and discharge problem are then day by day important to the raising of the requirement of living environment because of the improvement and the people of the seal of modern room.Though smoke exhaust ventilator is equipped with in the room that has, the disadvantage of still have flue gas to fill the air, smell is dense.What is more, and apocleisis, tired, dull-witted, illness such as get fat also appear in the cooking person of family who has.Find after deliberation, this is to contact for a long time due to the pyrolysate of edible fat, denatured protein and carbohydrate, simultaneously, and the still extremely strong cellular mutant agent that these pyrolysates have, can cause the sudden change and even the canceration of cell, cause very big threat to health.
The space diffusingsurface that we claim the powder flue dust to the distance of the absorbing surface of discharger is " the powder flue dust freely spreads height H ".Find that after deliberation it is very huge to the influence of the discharge effect of powder flue dust that the powder flue dust freely spreads the height of height H value.Usually, the powder flue dust freely spreads the discharge effect that height H is relevant to the powder flue dust.In other words, the powder flue dust freely spreads height H more greatly, and it is poorer that the powder flue dust is discharged effect; It is littler that the powder flue dust freely spreads height H, and it is better that then the powder flue dust is discharged effect.Certainly, in addition, the powder flue dust is got rid of science and the correctness that effect also depends on dust removal mechanism.
Prior art problems is: the powder flue dust that has freely spreads height H excessive (being generally H=30-100cm), and the powder flue dust is arbitrarily diffusion in its diffusion space, causes serious pollution; Though the powder flue dust that has freely spreads height little (can reach H ≈ 0), yet because the defective of dust-cleaning principle and technical immature lacks practicality.
With present smoke exhaust ventilator market is example, usually smoke exhaust ventilator is divided into air-exhaust type, side air-exhaust type and down air-exhaust type three classes.For last air-exhaust type smoke exhaust ventilator, its typical case is represented as more advanced deep suction type smoke exhaust; Offside air-exhaust type oil-fume removing machine, its typical case is represented as more advanced side draught wall built-up type smoke exhaust ventilator and vertical fume removing cabinet; To the down air-exhaust type oil-fume removing machine, air draft oil smoke discharging integrated range under its typical case represents and then is.
Deep suction type smoke exhaust ventilator, its classical architecture are that horizontal fan is placed, and at the air intake vent place of this blower fan, turn to 90 ° downwards, are aided with the deep-wall type wind scooper, the powder flue dust is freely spread height H be limited in about 70cm.H value about this 70cm just, though make the more traditional flat smoke exhaust ventilator of smoke exhaust ventilator of these types that bigger improvement be arranged, so to the discharge of thorough solution kitchen fume still apart from very far away.
Side draught wall built-up type smoke exhaust ventilator, its classical architecture are aided with guide duct, blower fan etc. again and constitute side draught type fume extracting system for a slim air draught casing to be housed on the sidewall above the kitchen range.The smoke exhaust ventilator of these types, powder flue dust freely spread height H ≈ 30cm.Yet, long oil smoke diffusion admittance, open oil smoke free air space still makes this kind of smoke exhaust ventilator to better people's living environment, and can not thoroughly purify kitchen space.
Following air draft oil smoke discharging integrated range, its classical architecture is for being provided with one group of inlet scoop and the blowing mouth be parallel to the pollution sources diffusion plane, and horizontal fan is positioned over the bottom of one kitchen range, constitutes the downward passing away of oil smoke by air ducting, and the blowing mouth wind regime is then established blower fan in addition.Its powder flue dust freely spreads height H ≈ 0.These designs, list near the limit, seemingly has its reasonability with regard to the powder flue dust freely spreads height; Yet this is the surface.In fact, this design exists significant deficiency and self to solve on dust removal mechanism.Single says, under the suction function of one deck inlet scoop that ring is put, knows that the pressure at the center of gravity place of this negative pressure wind field is zero (this near zone is so-called region of no pressure) by the known technology of this area with regard to the negative pressure wind field; Being in this negative pressure wind powder flue dust is after the match leaked owing to only being subjected to buoyancy at this region of no pressure place just.Certainly, because this design is provided with the malleation blowing mouth, this situation of leaking is improved.Yet known by fixed-point principle: exist a bit at least in the formed wind field under the synergy of the malleation of the negative pressure of described inlet scoop and blowing mouth, the pressure at this some place is zero; So formed new region of no pressure again at this near zone.This promptly says: region of no pressure can not be eliminated.This promptly says: the said dust-cleaning principle defectiveness of air draft oil smoke discharging integrated range down.This promptly says: the leakage of powder flue dust is inevitable in the dust arrester of said air draft oil smoke discharging integrated range down.In addition, desirable ground plane can not made with blowing mouth in the inlet scoop of horizontal positioned; The blower fan of horizontal positioned has also become the direct carrier of oil smoke.All these make this type of down air draft oil smoke discharging integrated range practicality and stranded in the imagination stage for want of.
In addition, other production facility is (such as the chemical reaction still; Dust recovery processing facilities etc.) the powder flue dust discharger of adapted also exists the shortcoming of big noise, high power consumption, low effect, the pollution problem that can't thoroughly solve the powder flue dust.
