Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily implement the present invention. The present invention can be implemented in various different ways, and is not limited to the embodiments described below.
It is noted that the drawings are exemplary and are not drawn to scale. Relative dimensions and proportions between parts shown in the drawings have been shown exaggerated or reduced in size, for the sake of clarity and convenience in the drawings, any dimensions being exemplary only and not intended to limit the invention. In addition, in order to show similar features, the same components, elements, or parts shown in two or more drawings are denoted by the same reference numerals.
The embodiments of the present invention specifically show the preferred embodiments of the present invention. As a result, various modifications can be envisioned as shown in the drawings. Thus, embodiments are not limited to the particular manner in which the regions illustrated are modified, including for example, by variations in the manner in which the fabrication occurs.
An economizer 100 for a boiler according to an embodiment of the present invention is described below with reference to the accompanying drawings.
Referring to fig. 1, an economizer 100 for a boiler according to an embodiment of the present invention includes a heat storage tank 110 and a heat exchange pipe 120.
The heat storage tank 110 is disposed at an exhaust gas discharge end 210 of the boiler 200.
Specifically, the heat storage tank 110 is located above the boiler 200, and communicates with the exhaust gas discharge end 210.
In the present embodiment, the heat storage tank 110 has a closed cavity 111, an air inlet 112 is opened at the center of the bottom plate of the heat storage tank 110, and the air inlet 112 is in sealed communication with the exhaust gas discharge end 210.
It should be noted that the space of the cavity 111 of the heat storage tank 110 is much larger than the inner diameter of the air inlet 112, and when the exhaust gas of the boiler 200 flows into the heat storage tank 110 through the exhaust gas outlet 210, the exhaust gas is collected in the cavity 111 and forms a high temperature layer.
In this embodiment, a heat insulating layer is further disposed on the inner wall of the heat storage tank 110, and the heat insulating layer can effectively prevent the heat inside the heat storage tank 110 from overflowing and dissipating.
In addition, the heat storage tank 110 has a funnel-shaped air outlet 113, and a narrower end of the air outlet 113 extends to the inside of the heat storage tank 110.
Because the gas outlet 113 adopts a funnel-shaped design with a wide upper part and a narrow lower part, the retention time of the high-temperature tail gas in the heat storage tank 110 can be effectively prolonged, and the heat exchange efficiency is further improved.
For example, the air outlet 113 and the air inlet 112 are arranged in a staggered manner, so that the high-temperature tail gas flowing from the air inlet 112 can be prevented from directly flowing through the air outlet 113 along the vertical direction, and the retention time of the high-temperature tail gas in the heat storage tank 110 can be further prolonged.
In the present embodiment, air outlet 113 is further provided with air outlet pipe 114, and air outlet pipe 114 is located above heat storage tank 110, for example.
The heat exchange tube 120 is disposed inside the heat storage tank 110, the heat exchange tube 120 is bent and coiled upward in the cavity 111 of the heat storage tank 110, and the water outlet 122 of the heat exchange tube 120 is located above the water inlet 121.
Specifically, the pipe heat pipe 120 is continuously bent in a plurality of U shapes inside the heat storage tank 110, and each bent section of the heat exchange pipe 120 is kept parallel.
In the present embodiment, the heat exchange tube 120 is located below the air outlet 113, and the water outlet 122 of the heat exchange tube 120 is located above the water inlet 121.
As an example, the heat exchange pipe 120 is located on a vertical plane.
In this embodiment, liquid water flows in through water inlet 121, flows through and flows out by delivery port 122 behind heat storage box 110 is inside, and liquid water is at the inside in-process that flows of heat storage box 110, and the high temperature tail gas that remains in heat storage box 110 is through the heat transfer with liquid water heating, accomplishes behind the thermal transmission, the temperature of high temperature tail gas reduces by a wide margin, has reduced thermal waste, and liquid water after the heating can flow back to boiler 200, can improve boiler 200's energy-conserving effect.
Compared with the prior art, according to the utility model discloses an economizer 100 for boiler through the reutilization to high temperature tail gas, can improve the heat energy conversion rate, can reach the energy-conserving effect of boiler.
In the above, the embodiments of the present invention have been described with reference to the drawings, but those skilled in the art to which the present invention pertains will appreciate that the present invention may be implemented in other ways without changing the technical idea or essential features of the present invention.
