Description
Technical Field
The application relates to a rotation type exhaust gas filtering device is applicable to exhaust-gas treatment's technical field, is particularly useful for forming machine exhaust-gas treatment and waste heat recovery's technical field.
Background
Many industrial waste gas all contain a large amount of solid particles or battings etc. if these waste gases do not pass through filtration treatment direct discharge, not only can cause the pollution to the air and bring the environmental protection problem, but also can cause the potential safety hazard to the normal operating of equipment, especially when having downstream equipment, still can cause the interference to the normal operating of downstream equipment.
The following description will take a setting machine in the textile industry as an example. The shaping machine can generate oil smoke containing organic matters and dye auxiliaries in the operation process, the main components of the oil smoke are aldehyde, ketone, hydrocarbon, fatty acid, alcohol, ester, lactone, heterocyclic compounds, aromatic compounds and the like, especially, a lubricant is added in the manufacturing process of yarns, and the components of the dye auxiliaries are more complicated during the after-finishing of functional fabrics for water resistance, flame retardance and the like. Meanwhile, after some fabrics are subjected to high-temperature setting, a large amount of wool fibers in the fabrics enter waste gas. Therefore, the waste gas of the high-temperature setting machine contains a large amount of oil smoke and solid particles, and can cause great pollution to the environment. The existence of the substances can easily cause potential safety hazards such as fire of the setting machine and the like. On the other hand, the setting machine is also the most energy-consuming equipment in the dyeing and finishing process, and a large amount of hot air is consumed during operation. However, the effective heat energy of the fabric during processing and shaping is only about 30% of the total heating amount, the heat dissipation loss is as high as 70%, wherein the heat loss of waste gas emission is about 60%, and the heat dissipation capacity of equipment and wall surfaces is about 10%. If the heat in the part of waste gas can be recovered and reused for operation, the waste of heat can be greatly reduced, and the energy utilization efficiency is improved.
The waste gas of the setting machine is filtered and cleaned, so that on one hand, oil smoke containing a large amount of organic matters and dye auxiliaries can be removed, and the discharged waste gas is cleaner; on the other hand, a large amount of waste heat in the waste gas can be recovered, so that the energy consumption of the setting machine is reduced. In the waste gas waste heat recovery process, the waste heat in the waste gas is generally recovered by adopting a heat exchange mode of a heat exchanger. The heat exchanger heat exchange pays great attention to the cleaning of the surface of the heat exchanger. If the waste gas and the heat exchanger are directly subjected to contact type heat exchange, the surface of the heat exchanger is easily scaled, the heat transfer resistance value is increased, and the heat exchange efficiency of the heat exchanger is reduced. Therefore, after the waste gas is filtered and cleaned, the waste gas exchanges heat with the heat exchanger, and the effective means for improving the waste heat recovery effect is provided.
However, generally the filtering of waste gas is realized through setting up the filter screen at the waste gas discharge outlet among the prior art, because solid particle thing and wool fibre in the waste gas are more, the forming machine will block up the filter screen after long-time operation for waste gas can't be discharged. At this time, the filter screen can only be manually cleaned after the setting machine is stopped, so that the cleaning efficiency is low, and the smooth printing and dyeing process is greatly influenced. On the other hand, because the exhaust gas of the setting machine contains a large amount of oily substances, the oily substances can be stuck on the filter screen. If the solid particles and the lint on the surface of the screen are simply removed during cleaning, a good cleaning effect is still not achieved, and the oily substance stuck on the screen increases the adhesion force to the solid particles and the lint, thereby making the screen more difficult to clean. Therefore, there is a need in the art for a filter device that can automatically and thoroughly clean a filter screen.
