Abstract

The utility model belongs to an apparatus for purifying smoke and removing dust, which is used on domestic boilers or kitchen ranges. The apparatus for purifying smoke and removing dust solves the problem which is desired to be solved for a long time and is severely harmful for people's health and environment. The apparatus for purifying smoke and removing dust has simple preparation process. The upper part of a drum of an external casing is conical; the inner part of the outer casing is provided with an internal flue with a wind cowl. A water spraying nozzle is arranged above the wind cowl; the lower part of an annular space between the casing and the internal flue is provided with a water discharging tube.

Description

Wind cowl-type smoke reducing duster directly installed on top of chimney

The utility model belongs to device for eliminating smoke and dust, is specially adapted to the smoke abatement and dust control of life cooking stove, because this device can be directly installed on stove, kitchen range smoke outlet, the bottom of chimney.

At present, the life cooking stoves of the overwhelming majority do not carry out smoke abatement and dust control, and flue gas directly is discharged in the atmosphere by chimney, and the chimney of life cooking stove generally can height, and is again the place that the crowd concentrates, serious harm people healthy.People urgently wish to solve this pollution problem for a long time, but never have a kind of simple device, and the utility model directly is contained in the blast cap formula device for abatement of smoke and dust on the chimney, can solve the problem of environmental pollution that life cooking stove poorly solves for a long time.

This device for abatement of smoke and dust, be to be contained on the lower flange (15) of boiler for domestic (1) smoke outlet chimney, flue gas comes out just to enter in the internal flue (4), from the circumferential weld of blast cap (7) and internal flue (4), get out in the ring casing (5), because the flip-flop of flue gas flow direction and flow velocity, dust is owing to the effect of gravity is just fallen in the water of ring casing (5), flue gas makes progress and the water counter current contacting of coming to spray to water pipe (12) sprinkler head (11), the washing flue gas, thereby finish the process of smoke abatement and dust control, the trunk of funnel (10) that purifies upper flange (9) dress of back gas by being contained in device for abatement of smoke and dust is discharged, and the operational effect that the water yield of sprinkler head (11) spray is looked device for abatement of smoke and dust can be used penstock (13) and be regulated.

Washings connect water band ash automatically by outlet pipe (14) and enter geosyncline, be deposited in part coal ash in the ring casing (5) and regularly connect water band ash by blow-off pipe (3) and be discharged in the geosyncline, but coal ash is reclaimed in the geosyncline periodic cleaning.(2) be sewage draining valve.

Accompanying drawing is that the utility model per hour is an embodiment on half ton the boiler for domestic in the steam raising amount:

At half ton of boiler for domestic, on the flange (15) of the chimney bottom of body of heater top 300mm, directly load onto blast cap formula device for abatement of smoke and dust, its internal flue (4) diameter is 250mm, ring casing (5) between shell (6) and internal flue (4), and blast cap (7) and internal flue (4) top clearance, their sectional area is all greater than the sectional area of internal flue (4), (8) 1/2 place's levels are adorned a water inlet pipe (12) on deduster awl row top, and on water pipe, adorn a sprinkler head (11), shower nozzle (11) is on the center line of deduster, adorn an outlet pipe in shell (6) bottom, the normal water level that keeps ring casing (5) be internal flue (4) high 1/2, this kind device, chimney and device for abatement of smoke and dust gross weight be less than the weight of former chimney, because little through water spray cooling back flue gas volume, the diameter of present chimney has only original 80%.

Claims

This device for abatement of smoke and dust, it is boiler for domestic and life device for eliminating smoke and dust with kitchen range, it is the smoke outlet that is directly installed on life cooking stove, it is characterized in that: at the smoke outlet of life cooking stove, the internal flue (4) of device for abatement of smoke and dust is housed on the flange of chimney bottom (15), blast cap (7) is arranged on the internal flue (4), water inlet pipe (12) is equipped with at 1/2 place of the capable top of the awl on the shell (6) (8) height, shower nozzle (11) is contained in water inlet pipe (12) exit, be positioned on the center line of deduster, automatic outlet pipe (14) is equipped with in shell (6) bottom.
