Drying and desliming system and process of plastic and fiber braided fabric waste

Abstract

The invention relates to a drying and desliming system of plastic and fiber braided fabric waste. The system is composed of a quantitative feeding device, a hot air compensation device, a drying machine main body, a steam supplying device, a condensate water discharging device, a discharging and desliming device and a tail gas collecting device; and the drying machine main body is a steam rotary cylinder. The invention further relates to a drying and desliming process of the plastic and fiber braided fabric waste. According to the drying and desliming system and process, the problems of long drying time, low heat utilization efficiency and secondary pollution exist in an existing plastic and fiber braided fabric waste drying process can be solved, and the plastic and fiber braided fabric after drying and desliming can be efficiently treated or recycled.

Description

technical field [0001] The invention belongs to the field of garbage treatment, and in particular relates to a plastic and fiber braided garbage drying and desliming system and process. Background technique [0002] With the rapid development of economies and the continuous improvement of productivity levels in various countries in the world, the environment has a greater impact on human beings, and environmental problems have become increasingly prominent and acute. Serious ecological damage and environmental pollution have become major problems facing contemporary society. [0003] The garbage pollutants produced in human production and life are mainly plastics and fiber woven fabrics. The traditional method of dealing with this kind of garbage is landfill. Although it can absorb a large amount of garbage, the landfill occupies a large area and has a short use time (generally Ten years or so), the cost is high, and it is easy to cause secondary pollution of groundwater re...

Problems solved by technology

However, the biggest problem facing domestic waste in our country is the high water content of the waste. In some areas, the water content of the waste is even greater than 50%. It is very difficult to incinerate waste with high moisture and low calorific value. Not only will the incineration be incomplete, but also harmful gases will be produced, such as two Oxygen, HCl, SO 2 , increasing the difficulty of flue gas treatment

At present, the commonly used drying methods are hot air and biochemical drying. The obvious disadvantages of these two treatment methods are: 1. Large area; 2. Long drying time and low efficiency; 3. Low heat utilization efficiency, and a large amount of hot air Being carried and emptied greatly increases the operating cost; 4. The amount of exhaust gas treatment is large, and there is a risk of secondary pollution; 5. The material is not passed smoothly, and maintenance is frequent, which increases a large amount of unnecessary operating costs; 6. Plastics and fibers cannot be effectively separated The moisture and soil wrapped in the braid are removed, resulting in the generation of toxic and harmful gases and residues that are not up to standard defects during incineration and cracking

Invention patent CN106391240A discloses a medical plastic waste disposal device. The right end of the output shaft of the motor is connected to a rotating shaft, and the right end of the rotating shaft is connected to the right side wall of the box through a bearing. , it is unavoidable that there is winding phenomenon on the rotating shaft, which will definitely affect the operation and work efficiency of the device

The method of artificial collection will cause great harm to the physical and mental health of workers
