Problems solved by technology
The two pelletizing systems have their own advantages and disadvantages, and both carry a small amount of dust to varying degrees, but the hot pelletizing system on the die surface separates part of the dust during the water cooling process, and the cold pelletizing system cannot be separated and directly enters the product.

Embodiment
[0030] Taking 120,000 tons a year as an example, the annual investment is about 80,000 yuan. The particle dust content is between 2-5 / 10,000, and some may be larger. The dust content of the cold granulation system is about 7-9 / 10,000, and the dust content is calculated as 4 / 10,000. 50% meter:
[0031] 120000*0.0004*50%=24 (tons);
[0032] The amount of escape into the next process is calculated as 40% of the remaining amount:
[0033] 120000*0.0004*(1-50%)*40%=9.6 (tons);
[0034] That is to say, the current production plant with an annual output of 120,000 tons of polymers produces no less than 33 tons of dust pollution to the environment, and the amount of dust discharged by the elbow pipe on the top of the storage tank is even greater.
[0035] Use the recyclable dust of the present invention:
[0036] 120000*0.0004*70%=33.6 (tons);
[0037] The emission of remaining dust is still based on 50%:
[0038] 120000*0.0004*(100-70%)*50%=7.2 (tons);
[0039] Entering the ne...

The invention relates to a homogenization system with a granule powder removal system. The homogenization system comprises a storage tank, a feeding pipe, a Roots blower and a cyclone separator or an air relief elbow, wherein a granule powder removal device is arranged on a pipeline between a gate valve at the bottom of the storage tank and a rotary feeder; the granule powder removal device comprises a powder removal box, a filtering net in the powder removal box, and a curved material channel consisting of a material inlet in the top of the powder removal box, a passageway formed by a filtering net, and a material outlet in the bottom of the powder removal box; the filtering net comprises a folded filtering screen plate consisting of a surface AB and a surface BC, an a straight filtering screen plate consisting of a surface DE; the folded surface of the folded filtering screen plate and one side of the powder removal box form a first dust collecting chamber, and a first dust collecting pipe is arranged below the first dust collecting chamber; and the straight filtering screen plate forms a second dust collecting chamber with side plates and a bottom plate of the powder removal box, and a second dust collecting pipe is arranged above the bottom plate. According to the homogenization system, the influence to the downstream machining process is reduced, the environmental pollution is reduced, and the system has obvious effects on soil conservation, water pollution reduction and atmospheric pollution.
Description
technical field [0001] The invention relates to a dust-removing and powder-removing homogenization system for granular materials with dust and powder, in particular to a homogenization system with a device for removing powder for granular materials. Background technique [0002] Environmental pollution refers to the phenomenon that humans directly or indirectly discharge substances or energy that exceed their self-purification capabilities to the environment, thereby reducing the quality of the environment and causing adverse effects on human survival and development, ecosystems and property. Specifically include: water pollution, air pollution, noise pollution, radioactive pollution, etc. With the development of science and technology and the improvement of people's living standards, environmental pollution is also increasing, especially in developing countries. The problem of environmental pollution has increasingly become one of the common topics of all countries in the ...
