Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tail gas treatment, in particular to a pipeline structure used for treating hot tail gas from spray drying of essence materials. Background Art
[0002] In the production process of preparing flavor materials, the flavor raw materials need to be spray dried. The current treatment method for the generated hot exhaust gas is to install a dust filter at the exhaust outlet of the spray drying equipment to remove large dust particles, and connect the spray drying hot exhaust gas exhaust pipe equipped with a centrifugal fan to the exhaust end of the dust filter. A horizontal pipe is installed under the ceiling and connected to the spray drying hot exhaust gas exhaust pipe. The other end of the horizontal pipe is connected to a vertical pipe extending to the roof of the workshop to discharge the hot exhaust gas. As the equipment continues to run, since the dust filter cannot effectively filter dust with smaller particle sizes, and the height of the vertical pipe is relatively large, under the action of gravity, these smaller dust particles are easily accumulated on the pipe wall of the vertical pipe and at the bend between the vertical pipe and the horizontal pipe, which will affect the discharge of hot exhaust gas. At the same time, such a structure is not easy to clean the accumulated dust. Utility Model Content
[0003] The purpose of the utility model is to provide a pipeline structure for treating hot exhaust gas from spray drying of flavor materials. By adding a three-way connecting pipe and a collecting pipe for collecting dust between the existing horizontal pipeline and the vertical pipeline, the dust accumulated in the collecting pipe can be discharged by opening the sealing cover, which well solves the problems mentioned in the above-mentioned background technology.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A pipeline structure for treating hot exhaust gas from spray drying of an essence material comprises a spray drying hot exhaust gas exhaust pipeline connected to a centrifugal fan, wherein the spray drying hot exhaust gas exhaust pipeline is connected to a horizontally distributed first pipeline, the other end of the first pipeline is connected to a three-way connecting pipe, the other two end interfaces of the three-way connecting pipe are respectively connected to a vertically distributed second pipeline and a collecting pipe, the first pipeline, the second pipeline, the collecting pipe and the three-way connecting pipe are located on the same vertical plane, the second pipeline extends to the roof of a workshop at one end away from the three-way connecting pipe, the lower end of the collecting pipe has a discharge outlet, and the discharge outlet is provided with a sealing cover.

In this way, dust falling from the vertically distributed second pipe will directly fall into the tapered tube and smoothly slide along the inner surface of the tapered tube into the collecting tube.
[0010] Furthermore, the sealing cover is fixed to the discharge port through a clamp assembly.
[0011] Furthermore, the clamp assembly includes a first C-type clamp and a second C-type clamp that are rotatably connected, the free end of the first C-type clamp is provided with a first connecting plate, the first connecting plate is rotatably connected with a threaded rod, the threaded rod is installed with a rotary cover, the free end of the second C-type clamp is provided with a second connecting plate, the second connecting plate is provided with an embedding opening for embedding the threaded rod, the outer periphery of the discharge port has a circularly distributed positioning edge, and the cross-sectional shape of the first C-type clamp and the second C-type clamp are both "concave" shaped.

[0012] Furthermore, a spraying device for water spraying and flushing is arranged on the roof of the workshop, so that the second pipes and the collecting pipes distributed vertically can be flushed and cleaned by water spraying and flushing to remove the dust stuck on the surface.
[0013] Furthermore, the spraying device includes a water pipe with a control valve, and the water pipe is connected to a spray head that sprays water toward the inside of the second pipeline.
[0014] Compared with the prior art, the utility model provides a pipeline structure for treating hot tail gas from spray drying of flavor materials, which has the following beneficial effects:
[0015] The utility model adds a three-way connecting pipe and a collecting pipe for collecting dust between a horizontally distributed first pipe and a vertically distributed second pipe. The dust accumulated on the inner wall of the second pipe will easily fall into the collecting pipe as the accumulation amount increases and under the action of gravity, thereby preventing dust accumulation from clogging the first pipe and the second pipe. In addition, the dust accumulated in the collecting pipe can be discharged and cleaned in time by opening the sealing cover at a fixed time, thereby ensuring that the pipe structure maintains unobstructed exhaust.

Specifically, the pipeline structure for treating hot exhaust gas from spray drying of flavor materials includes a spray drying hot exhaust gas discharge pipeline 1 connected to a centrifugal fan 11, the spray drying hot exhaust gas discharge pipeline 1 is connected to a horizontally distributed first pipeline 2 fixed under the ceiling, the other end of the first pipeline 2 is connected to a three-way connecting pipe 3, and the other two ends of the three-way connecting pipe 3 are respectively connected to a vertically distributed second pipeline 4 and a collecting pipe 5, the first pipeline 2, the second pipeline 4, the collecting pipe 5, and the three-way connecting pipe 3 are located on the same vertical plane, the second pipeline 4 extends to the roof of the workshop at one end away from the three-way connecting pipe 3, and the lower end of the collecting pipe 5 has a discharge port 51, and the discharge port 51 is installed with a sealing cover 6. By adding a three-way connecting pipe and a collection pipe for collecting dust between the horizontally distributed first pipe and the vertically distributed second pipe, the dust accumulated on the inner wall of the second pipe will easily fall into the collection pipe as the accumulation amount increases and under the action of gravity, thereby preventing dust accumulation from clogging the first pipe and the second pipe. In addition, the dust accumulated in the collection pipe can be discharged and cleaned in time by opening the sealing cover at regular intervals to ensure that the pipe structure remains unobstructed and ventilated.

[0025] In some specific embodiments, reference Figure 2 and Figure 3The sealing cover 6 is fixed at the discharge port 51 through the clamp assembly 8, so as to realize the quick opening and closing of the sealing cover to clean the dust.
