5. Application of polymer precise microporous filtration technology in industrial production
Polymer precision micropore filtration technology is a new type of filtration technology with high efficiency, long-term efficiency and low cost. However, whether the success of a certain engineering application in various industrial production can fully demonstrate the inherent advancement of the technology. It depends entirely on the human factors in the design, manufacture, use and management of precision microporous filters.
Polymer precise microfiltration technology is a highly efficient, long-lasting and cost-effective new filtration technology. But whether in a given engineering application it can achieve success and fully demonstrate the inherent nature of the technology or not in a variety of industrial productions, is Depending on the design, manufacture, use and management of precise microporous filter.
The designer of the precision micropore filter must fully understand the detailed technical requirements of the filter used for the specific production process and the matching requirements of the upstream and downstream devices of the filter to the filter; the filter characteristics of the filtered material. It should be carefully and systematically tested and calculated; the model and specifications of the microporous filter tube, the model and specifications of the precision microporous filter, the model and specifications of the auxiliary device, and the engineering equipment layout at the production site should be correctly calculated and Strict design, on this basis, according to the design requirements to guide the manufacture and procurement of polymer microporous filter tubes and precision microporous filter manufacturing and auxiliary equipment, installation and acceptance according to design requirements. According to the design requirements, the correct application of the precision microporous filter management procedures, operating procedures and maintenance procedures. A lot of practice and many experiences and lessons show that the above-mentioned series of systematic engineering work, where the ring is tight, and carefully and carefully, can make it run successfully in production for a long time, creating significant economic benefits and society for users. Benefits; if there are one or several links that are sloppy, it will cause the whole device to be "sickly operated", but the whole case will fail. There are also examples of successful experiments that are not performed in advance, not strictly calculated and designed, but most of them are occasions where the filtering is not difficult, the requirements are not high, or the application scale is small. Precision microporous filtration projects that are difficult to handle large-scale difficult-to-filter materials must be carried out in strict accordance with the above procedures.
The designer of precise microporous filter must be fully aware of the detailed technical requirements of its selected filter for the specific production process, and the matching requirements of filter devices for upstream devices and downstream devices. For the filtration characteristics parameters of filtered suspension, it should Be careful and systematic tested and calculated. For the models and specifications of microprorous filtration tube, the models and specifications of precise microporous filter, the models and specifications of assist devices, and the engineering equipment layout of the production site, it should be determined On the above basis of work, according to design requirements, guide the manufacturing of polymer microporous filter tubes and precise microporous filters, and the manufacturing and procurement of auxiliary devices. According to design requirements, finish the installation, inspection and acceptance. According to design require Substation, some of the above-mentioned precise microporous filter must be drew up. Substantial practical experience and and the incident with many incidents prove in case that the above-mentioned series of system engineering work can be finished with each other close And careful interlink, finally the filtration project would be successful for long term, and can create significant economic and social benefits for the user. If there is one aspect or more which is perfunctory, it will cause "sick running" of the entire device and So much so that can lead to complete failure badly. There are success examples which also get easy use with no pre-experiment, non-strict calculation and design, because that most are a number of filtrations which are not difficult, having no high requirement Or having smaller application scale.
