Abstract
The invention relates to the technical field of catering purifying equipment, in particular to a fume exhaust hood used for purifying catering oil fume. The fume exhaust hood comprises a fume exhaust hood shell and a purifier shell. A plurality of purifying units are arranged in the space defined by the fume exhaust hood shell and the purifier shell. An air inlet system, a spraying system and a dewatering system are arranged in each purifying unit. The air inlet systems are used for introducing the oil fume into the purifying units. The spraying systems are used for fully atomizing purifying water and making the atomized purifying water fully mixed with oil fume airflow entering the purifying units, and therefore most of pollutants in the oil fume can be stuck to atomized micro-droplets. The dewatering systems are used for removing mixtures formed by the oil fume pollutants and the micro-droplets after atomization, the catering oil fume can be efficiently purified after atomizing and dewatering, and pollution to the atmosphere is avoided; and meanwhile the mixtures are prevented from being gathered into a fume exhaust pipeline. By means of the fume exhaust hood, the purifying water can be cyclically used through the technological methods of filtering, oil draining, dirt discharging and the like, and the water saving function is achieved.

Be worth explanation, the quantity of the scale visual kitchen range top 12 of this enforcement enclosure and the space in kitchen and determine, on the basis of said structure, its size can flexible design, such as: for two eyes propagandize hotly stove produce propagandize hotly oil smoke carry out purified treatment time, the appearance and size of its body (not containing water supply, backwater and water purification system) is length × wide × height=4300mm × 600mm × 750mm, and its process oil smoke amount is 8500m
3/ h; For the material of enclosure, all devices are all made by fire proofing, to eliminate hidden fire-fighting danger.
The present invention for purifying the course of work of the enclosure of kitchen fumes is:
Before using, open water injection valve 8, running water enters in water tank 4 through water injection pipe 7 and ball-cock assembly 6, and when the running water in water tank reaches regulation liquid level, ball-cock assembly 6, under buoyancy, cuts off for water route.
During work, enter into by shutter 15, air inlet elbow 16, extension mouth 17 interior volume that enclosure housing 19 and purifier shell 31 surround a square-section propagandizing oil smoke that the kitchen range top 12 produces through culinary art hotly, encounter at extension mouth 17 place the high-velocity flow that the umbrella shape jet angle sprayed from shower nozzle 18 is 90 °; These current have shrouded the oil smoke air-flow in air inlet elbow 16 exit completely, ensure that fully mixing of current and oil smoke air-flow, exist without the soot gas not contacting current.Now, the contamination particle in oil smoke air-flow and the microlayer model of current fully combine, and form a large amount of fog-zone containing fume pollution particle.
Wherein, some water after the injection along the inner tubal wall of air inlet elbow 16 toward dirty, these water will flow to the bottom of purifier shell 31 by drainpipe 14, then flow back in water tank 4 by backwater pipe collar 13 and return pipe 11, for continuing to recycle.
And the microlayer model air-flow of a part containing fume pollution particle continues to rise in addition, run into the dewatering system of multilayer stainless steel dewatering device silk screen 29 composition of horizontal wrap on dehydrator framework 27 lower planes.Major function device is wherein stainless steel dewatering device silk screen 29, for the microlayer model containing fume pollution particle a large amount of in this ascending air is removed, clean gas flow after removing the microlayer model containing fume pollution particle enters smoke exhaust pipe 20 by enclosure trunnion 24, smoke exhaust pipe trunnion 21, realizes clean emission.
These microlayer model be removed can be condensed into the larger drop containing fume pollution particle of particle diameter, under its Gravitative Loads, can along the inner tubal wall of enclosure housing 19 and purifier shell 31 toward dirty, flow to bottom purifier shell 31, then flow back into the non-purifying area of water tank 4 right-hand part by backwater pipe collar 13 and return pipe 11.Backflow addle in water tank 4 through first double-filtration filtration of imitating water sieve 9 and middle effect water sieve 5, thus enters the purifying area of the left side of water tank 4, for continuing to recycle.
After this dewatering system uses a period of time, multilayer stainless steel dewatering device silk screen 29 may be blocked by some impurity, causes flowing resistance to strengthen, causes exhaust smoke level to decline.Now, wing nut 26 is screwed off, the dehydrator cover plate 24, dehydrator framework 27 and the stainless steel dewatering device silk screen 28 that link together are pulled out from dehydrator grooved guide rail 29, to be cleaned or after changing stainless steel dewatering device silk screen 28, reinstall again, continue to use.
After long-time use, water pump 1 is shut down, after the clear water in water tank 4 leaves standstill a period of time, greasy dirt in water is lighter than water because of proportion, will form clc layer, and open draining valve 10 at liquid level top, the clc layer at liquid level top is discharged, reaches the object of Cress water; In addition, the right-hand part of water tank 4 can deposit some filter after sediment, now, open blowoff valve 30, the sediment after filtering is discharged, and then row opens water injection valve 8, running water enters in water tank 4 through water injection pipe 7 and ball-cock assembly 6, and when the running water in water tank 4 reaches regulation liquid level, ball-cock assembly 6 is under buoyancy, cut off water supply line, to continue to use.
Through Site Detection after the present invention uses for the enclosure purifying kitchen fumes: in this enclosure import department, oil smoke discharge concentration is 13.9mg/m
3; Be 0.19mg/m in this enclosure exit oil smoke discharge concentration
3, purification efficiency is 98.6%; Discharge complete concentration to meet the requirement of GB18483-2001 " cooking fume discharge standard " (the highest permission concentration of emission of this standard is 2mg/m
3).
Embodiments of the invention provide in order to example with for the purpose of describing, and are not exhaustively or limit the invention to disclosed form.Many modifications and variations are apparent for the ordinary skill in the art.Selecting and describing embodiment is in order to principle of the present invention and practical application are better described, and enables those of ordinary skill in the art understand the present invention thus design the various embodiments with various amendment being suitable for special-purpose.
