Description
本發明係與瓦斯燃燒裝置有關；特別是指一種用以將瓦斯與空氣混合的瓦斯混合器。 The invention relates to a gas burner; in particular to a gas mixer for mixing gas with air.
傳統的大氣式瓦斯燃燒裝置係在燃燒器的入氣口處設置噴嘴，利用瓦斯自噴嘴輸出時噴嘴周圍形成的低壓將一次空氣引入燃燒器內與瓦斯混合，再由燃燒器的出火孔輸出瓦斯，瓦斯引燃後形成火焰，且火焰燃燒時，由火焰的周圍再引入二次空氣燃燒。另一種形式的瓦斯燃燒裝置為全預混式，其係利用鼓風機引入空氣至燃燒器中而與瓦斯混合，並自燃燒器的出火孔輸出混合後的瓦斯與空氣。 The conventional atmospheric gas combustion device is provided with a nozzle at the inlet of the burner, and uses the low pressure formed around the nozzle when the gas is output from the nozzle to introduce the primary air into the burner to mix with the gas, and then output the gas from the fire outlet of the burner. After the gas is ignited, a flame is formed, and when the flame is burned, secondary air is introduced into the periphery of the flame to burn. Another form of gas burner is a fully premixed type that uses air blowers to introduce air into the combustor to mix with gas and to output mixed gas and air from the fire exit of the combustor.
全預混式的瓦斯燃燒裝置，係以瓦斯混合管作為瓦斯與空器的混合，瓦斯混合管係利用文式管的原理，讓空氣氣流與瓦斯氣流在管體中混合。全預混式瓦斯燃燒裝置的燃燒效率雖高於大氣式瓦斯燃燒裝置，但瓦斯混合管的混合效果較難以控制，且瓦斯混合管的長度通常不長，空氣氣流與瓦斯氣流並無法在瓦斯混合管中有限的行進距離中均勻混合，其混合效率有限，導致燃燒裝置的燃燒效率無法進一步提升。 The fully premixed gas burner is a gas mixing tube used as a mixture of gas and air. The gas mixing tube uses the principle of a vent tube to mix the air flow with the gas flow in the tube. Although the combustion efficiency of the fully premixed gas burner is higher than that of the atmospheric gas burner, the mixing effect of the gas mixing tube is difficult to control, and the length of the gas mixing tube is usually not long, and the air flow and the gas flow cannot be mixed in the gas. Uniform mixing in the limited travel distance of the tube, the mixing efficiency is limited, and the combustion efficiency of the combustion device cannot be further improved.
有鑑於此，本發明之目的在於提供一種瓦斯混合器，可以讓空氣氣流與瓦斯氣流均勻混合。 In view of the above, it is an object of the present invention to provide a gas mixer that allows an air stream to be uniformly mixed with a gas stream.
緣以達成上述目的，本發明提供的一種瓦斯混合器，用以連通至少一燃燒器；該瓦斯混合器包含有一主體與一分流件，其中，該主體具有一入氣部與一混氣部，其中該入氣部具有相通的一空氣入口、一氣室、至少一瓦斯入口與一通氣口，其中該氣室位於該空氣入口與該通氣口之間，且該氣室具有二相對的壁面，該二壁面分別呈傾斜且彼此之間的距離係由該空氣入口往該通氣口的方向漸縮，該瓦斯入口位於其中一該壁面上；該混氣部具有一混合室，該混合室分別與該通氣口及燃燒器相通；該分流件設置於該氣室中且位於該瓦斯入口與該空氣入口之間，該分流件將該氣室分隔為第一空間與一第二空間，該第一空間與該空氣入口相通，該第二空間與該通氣口及該瓦斯入口相通；該分流件具有至少一通孔，該通孔面對其中一該壁面，且該第一空間與該第二空間透過該通孔相通。 In order to achieve the above object, the present invention provides a gas mixer for communicating at least one burner; the gas mixer includes a main body and a flow dividing member, wherein the main body has an air inlet portion and a gas mixing portion. Wherein the air inlet portion has an air inlet, a gas chamber, at least one gas inlet and a vent, wherein the air chamber is located between the air inlet and the vent, and the air chamber has two opposite wall surfaces, The two walls are respectively inclined and the distance between them is gradually reduced from the air inlet toward the vent, the gas inlet is located on one of the walls; the mixing portion has a mixing chamber, and the mixing chamber and the The vent is in communication with the burner; the diverter is disposed in the plenum and is located between the gas inlet and the air inlet, and the diverter separates the plenum into a first space and a second space, the first space Communicating with the air inlet, the second space is in communication with the vent and the gas inlet; the flow dividing member has at least one through hole, the through hole facing one of the wall faces, and the first space and the second space Through communication between the through hole.

Each of the partitions 48 includes A first portion 482, a second portion 484 and a third portion 486 are respectively located in the second space 224, the air passage 24 and the mixing chamber 28, and each of the partitions 48 is embedded in the rear cover 36.

Each of the mixing chambers 28a has at least one of the gas outlets 46; each of the secondary spaces 224a communicates with at least one of the through holes 424a and at least one of the gas inlets 386.
藉由上述之結構，以下請配合圖9與圖10說明本實施例瓦斯混合器16用於混合瓦斯與空氣之情形。請參圖9，該鼓風機14之出風口142輸出的空氣自該空氣入口322注入該氣室22的第一空間222後，部分的空氣氣流將往上流動，部分空氣氣流受該二導引面324影導而沿著該二導引面324之表面往該空氣入口322的兩側流動，藉此，讓空氣氣流也能導入第一空間222中位於空氣入口322兩側的區域，而不會只集中在空氣入口322上方。 With the above configuration, the gas mixer 16 of the present embodiment for mixing gas and air will be described below with reference to Figs. 9 and 10. Referring to FIG. 9, after the air output from the air outlet 142 of the air blower 14 is injected into the first space 222 of the air chamber 22 from the air inlet 322, part of the air flow will flow upward, and part of the air flow is received by the two guide surfaces. The 324 is guided to flow along the surface of the two guiding surfaces 324 to the sides of the air inlet 322, thereby allowing the air flow to be introduced into the first space 222 on both sides of the air inlet 322 without Focus only on the air inlet 322.
請續參圖10，空氣氣流由該分流件42的通孔424a,424a'進入第二空間224中，藉由分流件42可以避免空氣氣流形成渦流而影響氣流的行進。在分流孔426a未被封閉的情況下，部分空氣氣流亦由分流孔426a進入第二空間。由於第二空間224被分隔成多個次空間224a，因此，該些次空間224a的空氣氣流彼此不會相互干擾，讓空氣之氣流可以穩定地流動，且空氣氣流在次空間中受該二斜面342,382的導引而沿著該二斜面342,382的表面往上流動，藉以減少擾流。當空氣氣流通過瓦斯入口386時，將帶動瓦斯氣流往上流動，而一同進入該通氣口242a。而後，氣空氣流與瓦斯氣流經過次氣道24a並由出口244a注入至次混合室28a中。由於出口244a的位置位於次混合室28a的最外圍，因此，氣空氣流與瓦斯氣流將沿著次混合室28a的壁面繞轉，並由外而內逐漸往多邊形的幾何中心G移動，如此，可以讓氣空氣流與瓦斯氣流在次混合室28a中充分混合。在次混合室28a中，越接近外圍的氣流之流速高、壓力低，有利於混合；越接近幾何中心G的氣流之流速低、壓力高，因此，藉由出氣管46的第一端462鄰近幾何中心G(即鄰近混合室28中心)之設計，有利於讓呈高壓且均勻混合後的空氣氣流與瓦斯氣流更容易自第一端462進入出氣管46中，而自第二端464輸出至燃燒器10進行燃燒。 Referring to FIG. 10, the air flow enters the second space 224 through the through holes 424a, 424a' of the diverter 42. By the diverter 42, the air flow can be prevented from forming a vortex to affect the travel of the air flow. In the case where the split hole 426a is not closed, part of the air flow also enters the second space by the split hole 426a. Since the second space 224 is divided into a plurality of sub-spaces 224a, the air flows of the sub-spaces 224a do not interfere with each other, so that the airflow of the air can flow stably, and the airflow is subjected to the two bevels in the sub-space. Guided by 342, 382 flows up the surface of the two ramps 342, 382 to reduce turbulence. When the air flow passes through the gas inlet 386, it will drive the gas flow upwards and enter the vent 242a together. Then, the air-air flow and the gas flow pass through the secondary air passage 24a and are injected into the secondary mixing chamber 28a from the outlet 244a. Since the position of the outlet 244a is located at the outermost periphery of the secondary mixing chamber 28a, the air-air flow and the gas flow will be rotated along the wall surface of the secondary mixing chamber 28a, and will gradually move from the outside to the geometric center G of the polygon, thus, The gas air stream and the gas stream can be thoroughly mixed in the sub-mixing chamber 28a. In the secondary mixing chamber 28a, the flow velocity of the gas flow closer to the periphery is high, and the pressure is low, which is advantageous for mixing; the flow velocity of the gas flow closer to the geometric center G is low and the pressure is high, and therefore, the first end 462 of the gas outlet pipe 46 is adjacent. The geometric center G (i.e., adjacent to the center of the mixing chamber 28) is designed to facilitate the high pressure and evenly mixed air flow and gas flow from the first end 462 into the air outlet 46 and from the second end 464 to The burner 10 performs combustion.
此外，由於各該出氣管46的最小通道截面積之總和與該氣道24的最小通道截面積的比值介於1.1~0.9之間，換言之，氣道24與出氣管46的壓力相近，因此，當鼓風機14輸出的風量及瓦斯入口386注入的瓦斯量改變時，自出氣管46輸出的空氣量及瓦斯量將會迅速地相應改變，藉以縮短調整燃燒器10輸出之火焰大小的反應時間。 In addition, since the ratio of the sum of the minimum passage cross-sectional areas of the outlet ducts 46 to the minimum passage cross-sectional area of the air passages 24 is between 1.1 and 0.9, in other words, the air passages 24 are close to the pressure of the outlet ducts 46, and therefore, when the blowers are When the amount of air output of the 14 and the amount of gas injected by the gas inlet 386 are changed, the amount of air and the amount of gas output from the gas outlet pipe 46 will be rapidly changed accordingly, thereby shortening the reaction time for adjusting the flame size of the output of the burner 10.
