Description

A kind of cooking stove smoke gas purification retracting device

The utility model relates to a kind of equipment for kitchen use, particularly a kind of cooking stove smoke gas purification retracting device.

In recent years; people pollute for preventing and treating the kitchen oil flue gas always; for the protection environment is done effort; thereby the equipment of various oil extraction flue gases appearred; as exhaust fan, smoke exhaust etc., but these equipment mostly can only alleviate the pollution of the indoor oil smoke gas in kitchen, still can not solve the problem that oil smoke gas is discharged into outdoor pollution surrounding environment; particularly hotel, restaurant, they pollute even more serious to surrounding environment.The oil smoke gas that has indivedual restaurants to adopt running water that cooking stove is discharged at present washes purification, can alleviate pollution to surrounding air, yet, because discharging, the running water after the flushing formed secondary pollution, still can not thoroughly solve environmental pollution problems, with the running water flushing, also wasted great amount of water resources simultaneously.

The purpose of this utility model provides a kind of kitchen fume of discharging that can make and is so incensed that purification, can prevent the cooking stove smoke gas purification retracting device of the secondary pollution of sealing again, and makes the oil gas recovery or recycling as far as possible of its processing.

The technical solution of the utility model is as follows:

This cooking stove smoke gas purification retracting device comprises cooking stove, collection mist extractor gas hood, reaches purification recovering mechanism three parts, and its special character is: described cooking stove is the oil gas cooking stove or the coal-fired stove of tape drum blower fan; Described collection mist extractor gas hood is installed in the top of cooking stove, comprise case and be installed in the case lower end connect oil storage box and upper end be equipped with the band exhaust fan the mist extractor tracheae; Described purification recovering mechanism is divided into two parts, the conical Whirlwind barrel of top for standing upside down, the bottom is the storage tank that contains water liquid and leave air storage chamber above the water liquid, the Whirlwind barrel vertex of a cone has opening, insert in the storage tank down, be equipped with upper end in the Whirlwind barrel can be to the sparge pipe and the fountain head of cylinder inboard wall water spray, and be communicated with water liquid in the storage tank by being installed in outer water-supply-pipe of Whirlwind barrel and water pump, this moment, water liquid can flow back to storage tank by water pump lifting after sparge pipe and fountain head are injected into around the Whirlwind barrel inwall, form the circulation of water liquid, the Whirlwind barrel upper end has the import of oil smoke gas and is communicated with the mist extractor tracheae of collection mist extractor gas hood, the oil smoke gas of discharging can enter Whirlwind barrel, and the flushing that moves down through water liquid along barrel purifies the air storage chamber discharge that enters storage tank again.

The purification recovering mechanism of this cooking stove smoke gas purification retracting device also is provided with an exhaust gas purification pipe, its inlet end stretches into central lower in the Whirlwind barrel, exhaust end stretches in the air storage chamber of storage tank under the Whirlwind barrel lateral, the little fountain head that can spray water around the tube wall below is installed in the pipe of exhaust end, effect is to being purified once more by the gas of discharging in the Whirlwind barrel, and the water liquid of ejaculation flows back in the storage tank.

Also be provided with an exhaust outlet on the storage tank gas storage locular wall of this cooking stove smoke gas purification retracting device, it can be communicated with the blower inlet of cooking stove, makes the gas of discharge participate in burning once more, forms the gas circulation utilization.

Also be provided with a gas emission pipe on the cooking stove of this cooking stove smoke gas purification retracting device, it is communicated with the mist extractor tracheae of oil-collecting flue gas cover, gas fume after burning can directly be discharged in the purification recovering mechanism go.

Effect of the present utility model is fairly obvious, it has solved the problem that the kitchen oil flue gas purifies and discharges effectively, particularly owing to the circulation that has realized purifying waste water, the greasy dirt of bubbling through the water column can adopt chemical agent or alternate manner recycling, thereby prevented the pollution of water, simultaneously, when when water liquid purified gas does not also reach purpose, can burn through cooking stove once more by gas circulation, thereby solve the water and air secondary pollution problem comprehensively.This appliance arrangement is simple in addition, and is safe and reliable, is particularly suitable for large, medium and small all kinds of restaurant, hotel kitchen use, changes a little, also can be used for family's cooking stove.
