Solutions for PET washing lines regarding service life and wastewater treatment
pet washing line how to maintain a long service life?
1, A certain period of time to check the equipment components, whether there is a loose situation, and the corresponding treatment of it.
2, Assembly line to work every day for a certain period of time, the equipment will be placed for a long time will produce a lot of rust, the next use will bring a lot of trouble, put a long time will reduce the life of the equipment.
3、The operation of each piece of equipment is strictly in accordance with the equipment manual.
How to deal with the wastewater after PET washing, that is, to deal with the surfactants in it?
The PET washing industry is an industry that sends waste to the hall of fame, and its requirements are higher than those of the general processing industry! The following are the key facilities requirements: first of all, the choice of the material yard, general small cleaning plant (daily output of 2-3 tons) also need 3-5 acres of stacking site, too small will affect production. The site for a large washing plant will be even larger. Therefore, when planning to build a washing plant, the first thing to consider is the problem of the material yard. Next is the workshop, small pet washing line requirements of the workshop area to be about 150 square meters, require hardened ground, clean and tidy. Otherwise, after causing secondary pollution, only low price sales, the very good raw materials into inferior products. A real cleaning plant has very strict requirements for the workshop, only to achieve a level of cleanliness similar to that of a food factory, in order to make high-quality bottle flakes. There is never any room for secondary contamination. Of course, from the waste to the finished product is a very complex process, to make high-quality products, after more than a dozen processes to complete, the regular cleaning plant power consumption is very large, the general small cleaning line plus the crushing part, high-pressure cleaning machine parts with electricity should be in about 80KW, in places where electricity is tight, first of all, to solve the problem of electricity, in order to consider on this project. There is also the cleaning of a ton of PET bottle flakes water is about 5-10 tons, even now the best equipment, water consumption can not be less than 3 tons, in places where water is tight, on this project, there are certain difficulties.
The last is the drainage problem, cleaning wastewater contains chemicals such as alkali, phosphorus, surfactants, grease, and a lot of sand and other dirty things, this wastewater can be used for irrigation of farmland and trees, which can increase soil nutrients and increase land fertility (except for high-pressure water cleaners containing alkali too high). It can also be put into wastewater pits for natural evaporation. However, it must not be put into water sources such as rivers, lakes, and seas, as this will cause eutrophication of the water and destroy the ecological balance. When building a cleaning plant, consider the issue of drainage. To avoid causing environmental pollution. To sum up, the cleaning plant must meet the five basic requirements of construction: yard, workshop, electricity, water supply, and drainage. Therefore, the construction of a PET cleaning plant infrastructure needs to be of a high standard and strict requirements, not at all sloppy.
