Description

Technical Field

[0001] This utility model relates to the field of preheater technology, specifically to a channel for conveying foam material. Background Technology

[0002] There are two common types of preheaters in industry: cement kiln preheaters and boiler air preheaters. Cement kiln preheaters are used to preheat raw materials, while boiler air preheaters heat combustion air. Their "increase foam and reduce coal powder consumption" is a technology in combustion optimization, namely "foam combustion". This technology improves combustion efficiency by injecting bubbles into the flame. The foam is not generated by the preheater itself, but by a specially designed foam generation system. The material composition of foam is usually a mixture of water, air and surfactants. Surfactants reduce the surface tension of water and form stable bubbles. Injecting this foam into the combustion zone can increase the fuel surface area, improve combustion efficiency, and thus reduce coal powder consumption. In existing technologies, combustion-supporting foam is mostly sprayed into the combustion zone through a spraying system to play its role. However, during the spraying process, the foam may break prematurely due to interference from the external environment. Therefore, a channel for conveying foam material is proposed.

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

[0015] Please see Figure 1 - Figure 4 The present invention provides a channel for conveying foam material, comprising: a conveying pipe 1 and an inlet pipe 2 fixedly connected to the surface of the conveying pipe 1; The surface of the conveying pipe 1 is provided with an inlet, the inlet pipe 2 is installed on the inner wall of the inlet, one end of the inner wall of the conveying pipe 1 is provided with a filter component, one end of the filter component is provided with a blower 4, and the outer surface of the conveying pipe 1 is provided with multiple sets of air supply components. The gas supply assembly includes a manifold 5, multiple branch pipes 6 fixedly connected to the surface of the manifold 5, and a gas supply pipe 7 fixedly connected to the outer surface of the manifold 5.

Both filter screen 13 and filter screen 2 are installed on the inner wall of filter tube 11.

[0017] Specifically, the fan 4 draws outside air into the dust filter pipe 3, and through the guide shell 12, the air enters the filter pipe 11. The dust in the air is filtered by the first filter screen 13 and the second filter screen 14. Finally, the filtered air enters the conveying pipe 1 to convey the foam inside the conveying pipe 1.

[0018] Optionally, the outer surface of the dust filter pipe 3 is provided with an external thread 16, the inner surface of the conveying pipe 1 is provided with an internal thread that matches the dust filter pipe 3, and the inner wall of the dust filter pipe 3 is fixedly connected with a plurality of L-shaped limiting bent rods 15 that match the filter pipe 11.

[0019] Specifically, by rotating the dust filter tube 3, the dust filter tube 3 is separated from the conveying tube 1, making it easier to remove the filter tube 11 inside the dust filter tube 3. This allows for the cleaning of the filter screen 13 and filter screen 14 inside the filter tube 11 or the replacement of the filter tube 11, filter screen 13 and filter screen 14 with new ones, thus preventing dust from clogging the filter screen 13 and filter screen 14 during long-term use.

[0021] Specifically, the conveying pipe 1 is fixed by the fixing ring 8. In addition, one end of the steel wire rope passes through the fixing hole 10 on the surface of the connecting piece 9, and then the other end of the steel wire rope is fixed to the object above the conveying pipe 1. Example 2

[0022] Based on Embodiment 1, this embodiment includes: a support member provided on the inner wall of the fixing hole 10, the support member including a screw 18, a spring 19 sleeved on the surface of the screw 18, a nut 21 threaded to one end of the surface of the screw 18, and a support rod 17 fixedly connected to one end of the screw 18, a gasket 20 fixedly connected to the bottom of the support rod 17, and protective paint sprayed on the outer surfaces of the conveying pipe 1 and the feed pipe 2.

[0023] Specifically, when there is no fixing object above the conveying pipe 1 to match the wire rope, the screw 18 passes through the fixing hole 10 on the surface of the connecting piece 9, and then the screw 18 is threadedly connected by the nut 21, and the conveying pipe 1 is fixed by the support rod 17.

[0024] The workflow for this application is as follows: The feed pipe 2 is connected to the foam generating system, and the air supply pipe 7 in the air supply assembly is connected to an external air pump. Foam is generated by the foam generating system and falls into the conveying pipe 1 through the feed pipe 2. The fan 4 brings the external air into the dust filter pipe 3 and through the guide shell 12 into the filter pipe 11. The air is filtered by the first filter screen 13 and the second filter screen 14. Finally, the filtered air enters the conveying pipe 1 to convey the foam inside the conveying pipe 1. At the same time, the external air enters the manifold 5 through the air supply pipe 7. Then, the air is diverted into the conveying pipe 1 through the diversion pipe 6 on the lower surface of the manifold 5. Multiple sets of air supply assemblies blow air into the conveying pipe 1 from various angles to keep the foam inside the conveying pipe 1 in the center of the conveying pipe 1 and prevent the foam from contacting the inner wall of the conveying pipe 1.
