Abstract
The utility model discloses an exhaust collecting cylinder with noise reduction baffles. The exhaust collecting cylinder comprises an exhaust collecting cylinder body, and the top of the exhaust collecting cylinder body and the corner of a straight exhaust pipe are respectively provided with at least one of the noise reduction baffles. A gas mixture channel is arranged between each noise reduction baffle and the exhaust collecting cylinder body. The noise reduction baffle are arranged inside the inner wall of the exhaust collecting cylinder body so that the flow speed of gas produced in combustion can be lowered and the flow direction of the gas produced in combustion can be dispersed, therefore, the natural vibration frequency of a feed system of a burner in combustion is changed not to coincide with the natural vibration frequency of a combustion system of a water heater, and the resonance phenomenon is avoided.
Description
Technical field
The utility model relates to the heat exchanger system technical field, relates in particular to a kind of band noise reduction baffle plate exhaust set cylinder.
Background technology
Reinforced fuel gas water heater in the market, under the combined influence of various technical reasons and some adverse environment conditions (as combustion gas kind, fuel gas temperature, air themperature, atmospheric pressure, combustion gas Wobbe index, utensil mounting condition etc.), burning sonorant phenomenon often occurs at work, causes operating noise larger.The mechanism of sound of empathizing is that water heater sonorific vibration wave when ignition overlaps with the sonorant microwave under these conditions, causes covibration, the sound of empathizing.
Specifically, usually, the combustion system of reinforced fuel gas water heater (comprising the parts such as combustion chamber, blast pipe) has self a eigentone, and feed system (comprising the parts such as burner, blower fan) can form another eigentone again when burning.When these two eigentones reach or approach when consistent, combustion system and feed system will produce above-mentioned burning sonorant phenomenon.
At present, the way that solves above-mentioned burning sonorant phenomenon is mainly that water heater structure is suitably revised, and does like this while not only taking a lot of work but also has increased development cost.
Therefore, those skilled in the art is devoted to develop a kind of simple in structure, the set of the exhaust with noise reduction baffle plate cylinder that cost is low.
The utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of simple in structure, the set of the exhaust with noise reduction baffle plate cylinder that cost is low, solves the resonance phenomenon in combustion process.
The utility model provides a kind of set of the exhaust with noise reduction baffle plate cylinder, comprise exhaust set cylinder body, on described exhaust set cylinder body, place's noise reduction baffle plate at least is installed, between described noise reduction baffle plate and described exhaust set cylinder body, forms mixed-gas channel.
Preferably, described noise reduction baffle body is thin-wall part.
Preferably, described exhaust set cylinder is the rectangle after flanging.
Preferably, described exhaust set tube length square for the flanging angle be the rectangle thin-wall part that 140 degree, wall thickness are T0.8mm.Wherein, T means the object relative distance between two sides up and down, i.e. the thickness degree of object, and symbol " T ", unit is mm.
Preferably, the rectangular surrounding of described exhaust set cylinder flanging is led fillet.
Preferably, described noise reduction baffle plate is placed on the position of exhaust set cylinder near the edge, gas outlet.
Preferably, being provided with described noise reduction baffle plate can be single installation, also can be a plurality of installations that are symmetrical at the placement position of exhaust set cylinder.
Preferably, described exhaust set cylinder and acoustical panel is structure as a whole or the isolating construction installed for the screw self tapping.
Preferably, be provided with spot welding location dimension or screw mounting-positioning holes size in described exhaust set cylinder body.
The utility model in single exhaust set cylinder location and installation the noise reduction baffle plate, flow velocity and the flow direction alleviating and disperseed high-speed fuel gas, the flue gas that makes an original road discharge, shunt and go, upset flue gas and escaped excessive mode, time and path, make the intrinsic frequency of whole combustion system shift, avoided water heater to overlap with the resonant frequency of whole combustion system, to avoid the generation of sonorant.From configuration aspects, consider in addition, in the aiutage gas outlet, place increases the such structure of acoustical panel, has changed the intrinsic frequency of whole utensil, has further avoided the generation of sonorant.
The accompanying drawing explanation
Fig. 1 is the exhaust set cylinder schematic diagram of the utility model preferred embodiment;
Fig. 2 is the top view in Fig. 1;
Fig. 3 is the noise reduction baffle plate schematic diagram of the utility model preferred embodiment;
Fig. 4 is the top view in Fig. 3.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for the utility model is described, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a specific embodiment for the set of the exhaust with noise reduction baffle plate cylinder of the present utility model, comprise exhaust set cylinder body 1, on exhaust set cylinder body, noise reduction baffle plate 3 is installed, in the present embodiment, on exhaust set cylinder body, to be welded with the flanging angle be but that the rectangle thin-wall part surrounding that 140 °, wall thickness are T0.8mm is led fillet to point, also can not lead fillet.In the present embodiment, be the rectangle of rounding, fillet R=1.6.The part that the noise reduction baffle plate tilts is apart 5mm perpendicular to gathering the cylinder projector distance with the limit of set cylinder
In the present embodiment, the noise reduction baffle plate is thin-wall part 3.The noise reduction baffle plate can be single installation, also can be a plurality of installations that are symmetrical at the placement position of exhaust set cylinder 2.
Described noise reduction baffle plate 3 is set at close exhaust set cylinder 2 edges, gas outlet, top, the position of exhaust set cylinder.
Can also an acoustical panel be installed according to the Actual combustion situation on the air door body, even the polylith acoustical panel in conjunction with (not shown in figure 1).
In the present embodiment, as shown in Figure 2, noise reduction baffle plate and exhaust set cylinder body are structure as a whole.The isolating construction of perhaps installing for the screw self tapping.Be provided with spot welding location dimension or screw mounting-positioning holes size in exhaust set cylinder body.
In other embodiments, as shown in Figure 1 and Figure 2, preferably select a noise reduction baffle plate, in order to meet flue gas content and the thermal efficiency of discharging after burning, prevent from affecting other combustibilities.
In exhaust set barrel structure of the present utility model, the noise reduction baffle plate is fixed on the air exit edge.When practical, burner in working order in, the flue gas that burning produces is by novel exhaust set barrel structure the time, flow velocity and the flow direction of the gas produced by burning with alleviation and dispersion, this makes the eigentone of feed system when burning of burner that change occur, avoid this eigentone to overlap with the eigentone of the combustion system of water heater, thereby avoided the generation of sonorant phenomenon.
