In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected" and "disposed" are to be construed broadly, and may for example be fixedly connected, disposed, detachably connected, disposed, or integrally connected and disposed. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 4, the utility model provides a gasifier connecting pipe, which comprises a pipe body, a guide plate 5 and a spoiler 6;

The pipe body comprises an inlet end 1, an outlet end 2, an upper pipe body 3 and a lower pipe body 4 which are horizontally divided into an upper part and a lower part along the axial direction of the pipe body; the inlet end 1 is higher than the outlet end 2, and the upper pipe body 3 and the lower pipe body 4 are sealed through welding.

as shown in fig. 3, the plurality of guide plates 5 are arranged on the inner wall of the lower pipe body 4 at intervals, the guide plates 5 are obliquely arranged from the inlet end 1 to the outlet end 2, the height of each guide plate is gradually reduced, and the adjacent guide plates 5 are arranged in a staggered manner. The staggered arrangement is preferably as shown in fig. 3, for example, the higher end of one baffle 5 is located at one long side of the lower tube 4, the lower end of the baffle 5 is directed to the other long side of the lower tube 4 through the lowest part of the lower tube 4 and keeps a distance with the other long side, and the height of the other baffle 5 adjacent to the baffle 5 is arranged just opposite. The arrow in fig. 3 shows that the liquid light hydrocarbon flows in a direction schematic, and in the flowing process, the flow stroke of the liquid light hydrocarbon can be prolonged due to the effect of the guide plate 5, and part of the liquid light hydrocarbon can generate turbulent flow, rolling, vibration and the like, so that the contact area and the contact time with air or mixed gas above the liquid light hydrocarbon are increased, and the gasification and mixing effects are improved. In this embodiment, the liquid light hydrocarbon is mainly pentane.

As shown in fig. 4, a plurality of spoilers 6 are provided on the inner wall of the upper pipe 3 at intervals, the spoilers 6 are arranged obliquely downward from the inlet end 1 to the outlet end 2, and the lower ends of the spoilers 6 are spaced apart from the inner wall of the baffle 5 or the lower pipe 4. After air or mixed gas enters the pipe body, the airflow is rolled, mixed, disturbed and the like under the action of the spoiler 6, so that the gas is further mixed. The arrows in fig. 4 show the direction of the airflow. When the air current once and again passes through the spoiler 6, the diameter of the air passage (the channel in the pipe body through which the air can flow) changes for many times, for example, the diameter of the air passage is suddenly increased at the moment when the air current passes through the spoiler 6, so that the divergence speed of the air current can be accelerated, when the air current passes through the next spoiler 6 again, the diameter of the air passage is reduced, so that the air current is compressed, and after the diameter of the air passage changes for many times, the mixed gas is mixed more fully.

The tubular body profile in this embodiment is preferably a bent tube as shown in figure 1. Of course, the pipe body can be other forms of bent pipe or straight pipe. The inlet end 1 may be a vertical surface, a horizontal surface or an inclined surface, preferably a vertical surface in this embodiment, and the outlet end 2 is a vertical end surface or an inclined end surface, preferably a vertical surface in this embodiment. Of course, no matter how the setting direction of entry end 1 and exit end 2 is, entry end 1 must be higher than exit end 2, and this kind of injecture can be structural injecture, also can be the injecture of mounted position during the installation, satisfy promptly that the liquid light dydrocarbon that flows into from entry end 1 can not too much remain in the body, for example, after 10ml liquid light dydrocarbon flowed into the body, can gasify 2ml in the flow process, have 7 ~ 8ml in the remaining 8ml and can follow exit end 2 and flow out.

The gasifier connecting pipe with the structure can shorten the distance between the primary gasifier and the secondary gasifier, and compared with the traditional connecting pipe, the length of the pipe required for completing gasification or mixing with the same effect is shorter.

During manufacturing, the pipe body is formed by splicing (welding) an upper pipe body 3 and a lower pipe body 4, before splicing, the guide plate 5 is fixedly welded on the inner wall of the lower pipe body 4, and the spoiler 6 is fixedly arranged on the inner wall of the upper pipe body 3. When the gasifier is installed, the inlet end 1 is welded and sealed with the outlet of the first-stage gasifier, and the outlet end 2 is welded and sealed with the inlet of the second-stage gasifier. Of course, the outlet of the primary gasifier to which the gasifier connection pipe of the present embodiment is applied should be higher than the inlet of the secondary gasifier.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
