Abstract
The utility model relates to a noise reduction and gas exhaust passage structure of a gas water heater, which is mainly composed of an exhaust hood 1, a lower plate 2 and a gas exhaust opening 3, wherein the lower plate 2 is fixed in the exhaust hood 1. An inner space of the exhaust hood 1 is divided into a lower gas exhaust passage 7 and an upper gas exhaust passage 8. The lower plate 2 is orderly provided with a plurality of silencing holes 6 which are used for communicating the upper gas exhaust passage and the lower gas exhaust passage. One to a plurality of rectifying plates 5 are arranged in the upper gas exhaust passage 8, and are used for dividing the upper gas exhaust passage. The rectifying plates 5 form a n shape, and the rectifying plates are fixed on the lower plate 2 and/or the gas exhaust opening 3. Due to the shunting function of the silencing holes and the rectifying function of the rectifying plates, the utility model greatly reduces squeaking sound and noise when the gas is exhausted, and causes the exhausted noise of waste gas to achieve silent requirements.
Description
Technical field
The utility model relates to gas heater, specifically refers to a kind of exhaust channel structure that can reduce the gas heater exhaust noise.
Background technology
In the prior art, the exhaust channel structure of gas heater as shown in Figure 1, mainly form by hood 1, lower plate 2, exhaust outlet 3, hood 1 is fixed on the top of heat exchanger 4, lower plate 2 is fixed in the hood 1, and the inner space of hood 1 is divided into exhaust passage 7 and last exhaust passage 8 down.The high-temp waste gas that the burning back produces after over-heat-exchanger 4 enters hood 1, successively by lower channel 7 and upper channel 8, is discharged from exhaust outlet 3 at last.Because jumbo water heater, as jumbo off-premises station, capacity is bigger in use, when the air-flow of discharging turns to exhaust passage 8 through exhaust passage 7 hastily, can produce turbulent flow, again from exhaust outlet 3 ejections, can send very big noise, and supervene high frequency and utter long and high-pitched sounds, the environment around the influence.
Summary of the invention
The purpose of this utility model is to propose a kind of noise reduction sound exhaust channel structure of gas heater, and this structure of mat is to the shunting and the rectified action of air-flow, the noise when reducing the waste gas of water heater discharging significantly.
The noise reduction sound exhaust channel structure of a kind of gas heater of the present utility model, mainly form by hood 1, lower plate 2 and exhaust outlet 3, lower plate 2 is fixed in the hood 1, the inner space of hood 1 is divided into exhaust passage 7 and last exhaust passage 8 down, on described lower plate 2, has the bloop 6 of the upper and lower passage of some connections in an orderly manner.
On described, be provided with in the exhaust passage 81 to several piece on the cowling panel 5 separated of exhaust passage, described cowling panel 5 is ∏ shape, is fixed on the lower plate 2 and/or exhaust outlet 3 places.
Effect of the present utility model is, because burning back waste gas, after entering hood 1 by heat exchanger 4, can shunt through bloop 6, upper channel 8 two passes through upper channel 8 with from lower channel through lower channel 7, and after cowling panel 5 rectifications, just discharge from exhaust outlet 3, thereby reduced the strong noise and the howling that have sent when the turbulent flow in the air-flow has reduced toxic emission effectively significantly, made the toxic emission noise reach quiet requirement.
Description of drawings
Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing thereof.
Fig. 1 is existing gas heater exhaust channel structure schematic diagram;
Fig. 2 is an exhaust channel structure schematic diagram of the present utility model;
Fig. 3 A is that the A of lower plate of the present utility model is to view;
Fig. 3 B is the left view of Fig. 3.
Among the figure: 1 hood, 2 lower plates, 3 exhaust outlets, 4 heat exchangers, 5 cowling panels, 6 bloops, 7 lower channels, 8 upper channels.
The specific embodiment
An embodiment of the present utility model as shown in Figure 2, mainly form by hood 1, lower plate 2, hood 1 is fixed on the top of heat exchanger 4, lower plate 2 is fixed in the hood 1, the inner space of hood 1 is divided into exhaust passage 7 and last exhaust passage 8 down, have some bloops 6 on described lower plate 2 in an orderly manner, limit, the hole 6a of this bloop 6 is the flange shape, shown in Fig. 3 A, 3B.The air-flow of the 6 pairs of discharges of bloop on the lower plate 2 has shunting action, can reduce the flow velocity of discharging air-flow, reduces noise.
Be provided with 2 ∏ shape cowling panels 5 on described in the exhaust passage 8, wherein one is fixed on the lower plate 2, and another piece is fixed on exhaust outlet 3 places, and this cowling panel can be separated into two layers with going up exhaust passage 8, referring to Fig. 2.The air-flow of 5 pairs of discharges of described cowling panel has rectified action, can eliminate turbulent flow, further reduces howling.
Claims (4)
1. the noise reduction sound exhaust channel structure of a gas heater, mainly form by hood, lower plate exhaust outlet, lower plate is fixed in the hood, the inner space of hood is divided into exhaust passage and last exhaust passage down, it is characterized in that on described lower plate, having in an orderly manner the bloop of the upper and lower exhaust passage of some connections.
2. exhaust channel structure according to claim 1 is characterized in that described bloop is the flange hole.
