Description
The utility model relates to the energy-conservation flame damper of a kind of chimney, and it can control emerging of Mars in the chimney, is adapted to the fire protection requirement of forest zone and relevant fire prevention unit especially.
It is a lot of that forest fire all will take place every year, makes the country and people's lives and properties all be subjected to great loss.The survey showed that according to relevant department, and nearly 50% fire cause causes from Mars of emerging in the chimney or flame.Particularly in wind season, this disaster hidden-trouble is even more serious.At present, on Civil energy-saving cooking stove chimney and boiler chimney, the Mars or the flame that also do not have special equipment to go to eliminate from chimney, to emerge.
The purpose of this utility model provides a kind of device of falling of the Mars of emerging in the chimney or flame all can being put out, and can play the purpose of combustion-supporting and energy-saving.
The utility model is achieved in that
It is made up of flue 1, fume collecting chamber 2, kuppe 3, flow deflector 4 and rain cover 7.The entrance section of flue 1 is long-pending greater than discharge area, and fume collecting chamber 2 is sleeved on the flue 1, and fume collecting chamber 2 tops are frustum, rain cover 7 by support plate 8 be bearing in fume collecting chamber 2 directly over.In the inside of fume collecting chamber 2 kuppe and flow deflector are housed, perhaps only adorn kuppe (generally adopting more than two).
During use, this flame damper is directly covered on the chimney.If chimney warp suitable for reading is variant dimensionally with the flue 1 of this flame damper, can utilize reducer pipe to be connected.Because the cone effect of flue 1, and the cone effect on fume collecting chamber 2 tops make them have the effect that pulls flue gas.Owing to the kuppe of fume collecting chamber 2 inside or the existence of flow deflector, they have changed the direction (shown in arrow among the figure) of flue gas stream again, and the change of airflow direction has just produced centrifugal force.At first, in the dense smoke air-flow contained than flanker particle and the little Mars particle of part under action of centrifugal force, separated below of falling fume collecting chamber 2.Rest parts Mars particle is subjected to having the effect of the guide vane of certain angle once more in the motion process that makes progress with air-flow, make it change the direction of motion again, therefore, under action of centrifugal force, is all put out the bottom of dropping on fume collecting chamber 2.Thereby reach control Mars is taken out of chimney by air-flow purpose.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model (being used for Civil energy-saving cooking stove).
Fig. 2 is the structural representation (if not subsidiary air exhauster is the Civil energy-saving cooking stove type, if subsidiary air exhauster is a boiler-type) of embodiment 2 of the present utility model.

In Fig. 1, the tapering of kuppe 3 is 140 °, and following flow deflector 4 is 45 ° of right distortion angles, and last flow deflector 4 is 35 ° of left twist angles.Upper and lower flow deflector respectively has 24 blades.
In Fig. 2, the good degree that closes of kuppe 3 is 145 °, and flow deflector 4 is 45 ° of right twist angles, and flow deflector has 24 blades, if subsidiary air exhauster is a boiler-type, if not subsidiary air exhauster is the Civil energy-saving cooking stove type.Motor can adopt direct current generator.Air exhauster is contained in the top of flame damper, and its motor is installed in the rain cover, and fan blade reaches collection cigarette exit.
In Fig. 1 and Fig. 2, the gross area in the slit that the inner flue gas of flame damper can pass through should be greater than 1/3rd of exhanst gas outlet area.
In Fig. 3, kuppe 3 is that positive taper is installed, and its bottom and fume collecting chamber's 2 sidewalls leave the gap that flue gas passes through, the disc structure that flow deflector 4 becomes the blade of certain distortion angle to form by some (among the figure being 24).Among the figure, last flow deflector is 40 ° of left twist angles, and following flow deflector is 45 ° of right twist angles.The water conservancy diversion tube connector 5 of supporting flow deflector 4 is connected with the top of kuppe 3, and is covered with through hole around it.The tapering of kuppe 3 is 140 °.
In Fig. 4, for having the flame damper of two kuppes, it is made up of flue 1, fume collecting chamber 2, kuppe 3 and rain cover 7.Its kuppe 3 is cone-shaped, its conical surface is served as reasons, and several become the blade of certain distortion angle to form, kuppe 3 is two, its bottom surface is relative, after being connected as a single entity by water conservancy diversion tube connector 5, again by support plate 6 be bearing in flue 1 directly over, the periphery of kuppe 3 and fume collecting chamber's 2 sidewalls leave the gap that flue gas passes through, flue 1 entrance section is long-pending greater than discharge area, fume collecting chamber 2 is sleeved on the flue 1, fume collecting chamber 2 tops are frustum, rain cover 7 by support plate 8 be bearing in fume collecting chamber 2 directly over.Be covered with through hole around the water conservancy diversion tube connector 5, its lower end is connected with the bottom of following kuppe.Air exhauster can be equipped with in top at flame damper, and motor is installed in the rain cover, and fan blade reaches the fume collecting chamber exit.
