華宇凈化教你如何選擇合適的過濾器

              1.根據室內要求的潔凈凈化標準，確定末級的空氣過濾器的效率，合理地選擇空氣空氣過濾器的組合級數和各級的效率。如室內要求一般凈化，可以采用初效過濾器；如室內要求中等凈化，就應采用初效和中效兩級過濾器；如室內要求超凈凈化，就應采用初效、中效和三級凈化過濾，并應合理妥善地匹配各級過濾器的效率，若相鄰兩級空氣過濾器的效率相差太大，則前一級過濾器就起不到對后一級過濾器的保護作用。

             2.正確測定室外空氣的含塵量和塵粒特征。因為過濾器是將室外空氣過濾凈化后送入室內，所以室外空氣的含塵量是一個很重要的數據。特別是在多級凈化過濾處理，選擇預空氣過濾器時要將使用環境、備件費用、運行能耗、維護與供貨等因素綜合考慮后決定。

            3.正確確定過濾器特征。過濾器的特征主要是過濾效率、阻力、穿透率、容塵量、過濾風速及處理風量等。在條件容許的情況下，應盡可能選用、低阻、容塵量大、過濾風速適中、處理風量大、制造安裝方便、價格低的空氣過濾器。這是在空氣空氣過濾器選擇時綜合考慮一次性投資和二次性投資及能效比的經濟性分析需要。

            4.分析含塵氣體的性質。與選用空氣過濾器有關的含塵氣體的性質主要是，溫度、濕度、含酸堿及有機溶劑的數量。因為有的過濾器允許在高溫下使用，而有的過濾器只能在常溫、常濕度下工作，過濾器并且含塵氣體的含酸堿及有機溶劑數量對空氣過濾器的性能效率都有影響. 

                 1.According to the clean purification standard of the indoor requirements, the efficiency of the final air efficient filter is determined, and the combination series and the efficiency of air efficient air filter are selected reasonably.If the indoor requirements are generally purified, the initial efficiency filter can be adopted;If the interior requires medium purification, the first and medium efficiency filters should be adopted.If the interior requires ultra-clean purification, it should be filtered by primary, medium and high efficiency,reasonable and should be properly matched hepa filter efficiency, at all levels if the efficiency difference between two levels of high efficiency air filter is too large, the former level of hepa filter is not to the level of protection and high efficiency filter.

2. Measure the dust and particle characteristics of outdoor air correctly.Because efficient filters are used to filter outdoor air into the chamber, the dust of outdoor air is a very important data. Especially in the multi-stage purification filtration treatment, the selection of the pre-efficient air filter should be decided after comprehensive consideration of the environment, spare parts cost, operation energy consumption, maintenance and supply.

3.Determine the characteristics of high efficiency filters correctly.The characteristics of high efficiency filter are filtration efficiency, resistance, penetration rate, dust tolerance, filtration wind speed and air volume. In the case of allowable conditions, high efficient air filter with high efficiency, low resistance, high dust tolerance, moderate filtration wind speed, large air volume, convenient installation and low price are required. This is to consider the economic analysis needs of one-time investment and secondary investment and energy efficiency in the selection of air efficient air filter.

4.Analyze the nature of dust gas.The properties of dust gases associated with the selection of air efficient filters are mainly the quantities of temperature, humidity, acid-base and organic solvents. Because some efficient filter allows use at high temperatures, and some efficient filter can only work under normal temperature, constant humidity, efficient filter and dust gas containing acid and alkali and organic solvent quantity has an effect on the performance of high efficiency air filter efficiency.
