Problems solved by technology

[0003] In the existing technology, the cleaning of the moisture drainage pipeline needs to be shut down, and the cleaning can only be done after the pipeline is disassembled. The average single cleaning time is 8.6 hours, so it needs to be cleaned on non-production days, and in order to ensure the cleaning quality and safe operation, the cleaning work It must be carried out when the light is sufficient and the weather is good. On average, it can only be cleaned once or twice a month. However, due to the need to dismantle the pipeline during cleaning, it must be carried out during the shutdown time of the factory holiday, that is, there is a time difference with the cleaning demand, and it cannot be cleaned quickly. According to the needs of the pipeline, the alarm is often caused by insufficient air volume and air pressure in the pipeline. The average number of alarms per month is 9.6 times. The frequency of cleaning is related to the number of alarms.

Embodiment 1

[0027] Such as figure 1 As shown, a moisture removal system for silk production includes a moisture removal pipeline 1, a static pressure tank 2, an odor treatment device 3 and a sedimentation separation device 4. The moisture removal pipeline 1 includes a second pipeline 11, a first pipeline 12 and an exhaust pipeline 13, wherein the first pipeline 12 is a vertical pipeline, the second pipeline 11 is a horizontal pipeline, and the silk production equipment in the factory building (omitted in the figure) is connected with the second pipeline 11 on the roof of the factory building through the first pipeline 12 , and then the second pipeline 11 communicates with the settling separation device 4 , the static pressure tank 2 and the odor treatment equipment 3 in sequence, and the odor treatment equipment 3 communicates with the exhaust pipeline 13 .

[0028] Such as figure 2 As shown, the settling and separating device 4 includes a settling box 41 shaped as a cuboid. The settlin...

Embodiment 2~3

[0034] The difference from Example 1 is that the sedimentation separation device in the silk making moisture removal system in Embodiments 2-3 is replaced by a centrifugal separation device or an interception separation device in the prior art. The centrifugal separation device draws on the principle of centrifuge precipitated liquid suspension to separate the smoke and sand from the odor gas; while the interception separation device uses the principle of the Y-type filter to retain the smoke and sand impurities with the filter element to achieve the purpose of separation. Other components And connection relation is identical with embodiment 1, and its effect is as shown in table 1.

[0035] Table 1

[0036]

[0037] It can be seen from the above that the dust cleaning effect and cleaning cycle of the centrifugal separation device are similar to those of the sedimentation separation device, but the wind pressure loss is relatively large. The soot and sand cleaning eff...

Embodiment 4~5

[0039] The difference from Example 1 is that the included angle between the curved deflector and the top of the settling box in Examples 4-5, and other components and connections are the same as those in Example 1, and the soot removal effect is shown in Table 2 .

Abstract

The invention provides a moisture exhausting system for cut tobacco production. The moisture exhausting system comprises a moisture exhausting pipeline, a still pressure box and a peculiar smell treating device, wherein the moisture exhausting pipeline comprises a first pipeline and a second pipeline which are connected; the second pipeline is communicated with the still pressure box and the peculiar smell treating device; a gas-solid separation device is arranged on the second pipeline; the gas-solid separation device is positioned on the second pipeline and at the end, close to the first pipeline, of the still pressure box. According to the moisture exhausting system for the cut tobacco production, through the arrangement of the gas-solid separation device, tobacco sand and peculiar smell in the moisture exhausting pipeline can be effectively separated, and the non-detaching cleaning of the whole moisture exhausting system for the cut tobacco production can be realized through periodically cleaning the gas-solid separation device only.

Description

technical field [0001] The invention relates to a sewage discharge system for a tobacco factory, and more specifically, to a moisture discharge system for silk production. Background technique [0002] The cigarette factory will produce tail gas during the process of preparing shredded tobacco, which needs to be treated by the shredded moisture removal system. The exhaust gas first enters the static pressure box on the roof of the factory building through the moisture exhaust pipe, and then is discharged into the atmosphere after passing the treatment of odor treatment equipment such as pre-washing tank, convection tank and biological filter tank. Since the tail gas contains a large amount of solids such as smoke and sand, the pipes will accumulate scale such as smoke and sand. When the accumulation reaches a certain level, it will affect the air volume and pressure of the tidal discharge, which will directly affect the production process of shredded tobacco. Therefore, the ...
