The polyester production process will generate a large amount of waste water. At present, the anaerobic and oxygen-consuming biochemical treatment methods (so-called “dosingâ€) are adopted. Not only the raw material cost is high, but also there is a problem that the COD decline is not obvious and odors are generated. In order to meet the COD emission requirements, companies have to deal with it by dilution with water. The treatment of 1t of waste water requires 4t of clean water, which is not only a waste of water resources, but also because the organic matter in the waste water cannot be removed and the discharged water still has a bad smell. This set of stripping and incineration equipment includes separation of organic matter, collection of exhaust gas, incineration and reuse. Utilizing the characteristics of volatile organics in wastewater, the organics are separated from the water by heating. This process can reduce the COD of wastewater from the original 20000mg/L to 4000mg/L. It only needs a simple biochemical treatment. It can reach the emission standard of 1000mg/L. The separated organic matter is collected and incinerated for reuse. It can generate up to 0.8t steam per hour, which can meet the operational needs of the entire system. After the entire device is in operation, it can save 1.4 million yuan of drug investment and 1.6 million yuan of sewage charges every year. It can also save more than 1,000 tons of water every day, and the processing cost is only half of the original.
Light Girder Suspension Crane
Maximum load: 2000kg
Used to transfer materials overhead, our Light Girder Suspension Crane is especially suitable for use in workshop that have low ceilings as well as factories and sites made of lightweight steel frames where the bridge crane reaches its limit.
The modular design contains fewer standard parts that make crane assembly as easy as stacking blocks. With these modular parts, users can reassemble a new crane, according to the change in lifting requirements of the alterations made to the workshop.
Due to the ultra-light weight of the crane, there is little friction between the trolley wheel and the rail. Easily moved by hands, this suspension crane can move clumsy, heavyweight workpiece in a fast manner. Available also with the mechanical electrical chain hoist, hoist drive, electrical control device, and matched system, the crane requires limited maintenance and has a long service life.
This series of crane can run on both straight and curved rails. By using many other modular parts, it can be reassembled to become the single-girder or double-girder crane. Each of the modular parts is bored to the standard connector for its size. So the crane can be adjusted according to the layout of the worksite, in order to suit the specific material handling requirement and satisfy customer specific needs.
