Pipe exhaust fluff removal device

Abstract

The invention discloses a device for clearing fluff in pipeline waste gas. The device comprises a box, a drum and a driving device, wherein the box comprises a gas inlet and a gas outlet, the drum is rotatably arranged in the box and provided with a filter screen on the outer peripheral surface, and the driving device is in drive connection with the drum. The clearing device is characterized by also comprising a fluff removal brush and a fluff collection channel, wherein the fluff removal brush is arranged along the length direction of the drum and is close to the filter screen, the inlet end of the fluff collection channel is close to the fluff removal brush and the fluff collection channel also comprises an inlet end. The fluff removal brush and the fluff collection channel can automatically clear up fluff according to the extent of aggregation of fluff on the surface of the filter screen of the drum so as to ensure that the discharged waste gas can smoothly pass through the filter screen; moreover, the on-line clearing of fluff is achieved by the device, and thus the automatic working efficiency of clearing fluff in discharged waste gas is improved.

Description

technical field [0001] The invention relates to the field of fluff removing devices, in particular to a device for removing fluff in exhaust gas in a pipeline. Background technique [0002] The exhaust gas emitted by the textile printing and dyeing machine during operation not only contains a large amount of smoke composed of fibers and combustible dust (ie fluff) on the fabric, but also contains a large amount of oil mist and other harmful substances. The pipelines transporting the above-mentioned waste gas are prone to accumulate thick fluff and waste oil on the pipe wall due to long-term use. When the weather is relatively dry and the temperature is high, the fluff mixed with waste oil accumulated in the pipeline can easily cause spontaneous combustion, causing a fire and causing serious damage. security risks. [0003] In order to make the waste gas discharge of the model machine meet the national standard, there are usually two methods of water spraying treatment and e...

AI Technical Summary

Problems solved by technology

[0004] If you want to recover high-temperature waste heat from exhaust gas and achieve energy-saving goals, you usually use a tubular exchanger, and you must also filter out the fluff in the exhaust gas first, otherwise the fluff and waste oil in the exhaust gas will easily accumulate on the surface of the heat exchange tube over time. , thereby affecting the heat exchange efficiency and exhaust gas passing rate, and there is also the risk of fire

[0005] When the filter screen is used to directly remove the fluff in the exhaust gas, since a large amount of fluff will accumulate on the surface of the filter screen after a certain period of operation, workers need to remove the fluff on the surface of the filter screen and reuse it, which greatly increases the fluff removal. The time and cleaning costs cannot meet the increasingly efficient production needs; some manufacturers first pass the waste gas into the pool, and then process the above-mentioned pollution through sedimentation separation, filtration separation and other methods. The application number is 201310246801.1 Chinese invention patent application The technical literature published "Fluff Filtration Device" (publication number CN103285643A) discloses a fluff treatment device that can reduce the number of removals and efficiently utilize water resources. Filter cartridge, the box below the filter cartridge is equipped with a temporary storage bin. After the waste water is filtered through the filter cartridge, fluff and other impurities remain in the filter cartridge, while the filtered water first flows into the temporary storage bin, and then flows out after further circulation. Although when using this device to treat wastewater, the large filter area of ​​the cylindrical filter cartridge can reduce the number of removals, thereby achieving efficient use of water resources, but since the exhaust gas discharged from the textile printing and dyeing machine is a high-temperature gas, the exhaust gas must be passed through first. The method of entering the water tank for further treatment cannot make full use of the heat energy in the high-temperature gas, resulting in a certain waste of energy; in addition, the use of the above-mentioned fluff filter device also needs to be processed after production shutdown, so the fluff filter device disclosed in the above-mentioned documents still cannot be realized. Clearing online does not fundamentally solve the problem
