Theoretically speaking, ESP technologies are used for the purpose of removing particulate matters from gas streams by applying an electrostatic charge to the fume & mist particulate with electrons emitted from the cathode section of the high voltage electric field, and negative ions produced as a result of co-mingling and collision of electrons and air molecules. Following the negative electrostatic field created by the power supply, the negatively charged particulates would be attracted to the positively charged anode section and get captured, while the purified exhaust gas comes out clean.
Given the tiny size of the electrons (which is several orders of magnitude smaller than that of the fume & mist particulates) and the high density of electrons discharged (≥1× l08 / cm), ionization of fume & mist particulates entertained in the exhaust airflow would be practically inescapable.
Rather than simply due to the occasional collision, fume & mist particulates in the electric field are bound to be charged according to the rules of basic charging mechanisms, namely field and diffusion charging. Negatively charged particulates are bound to be attracted to the positively charged anode section and get captured, thus achieving an extremely high air cleaning efficiency.
In contrast to other air cleaning devices, ESP applies energy only to the particulate matter being collected and therefore impart very low pressure drop on the air stream. In most cases, it is not necessary to choose a 10 fan with much higher pressure for ventilation, resulting in a high –efficiency in its total consumption of energy (in the form of electricity)
Emissions of DOP plasticizer-based oily vapor from the processing of a wide variety of PVC product, such as synthetic leather, vinyl flooring, wallpaper, latex/vinyl gloves, anti-slip mats, flex banners, conveyor belts, PVC coated air socks, plastic wire mesh, etc. are contained and exhausted by the fume hood, then directed through the ventilation duct work and introduced into a water-cooled heat exchanger, where temperature of the exhaust gas can be cooled down to a certain level where conditions for the performance of the electrostatic precipitator (ESP) would be comparatively ideal. Oily contents in the exhaust gas, such as DOP, viscosity reducer, etc. are collected by the high voltage electric field created by our ESP, collection efficiency of which can reach up to ≥95%, while emissions of the processed exhaust gas would be legitimate. The collected oily particles coalesce into larger droplets, begin to flow, and drain from ESP. Featuring a comparatively high purity, the collected waste oil can still be recycled and used as raw material, or can be sold to the waste oil collector for further processing, thus the initial investment in this system can payoff over a short period of time.
1. Enormous efficiency:
Oil Mist Removal efficiency≥99%
Particulate removal efficiency ≥99% (at rated airflow capacity) .
2. Quanlity of waste oil collected by the ESP system can be huge, and collected oil features a comparatively high purity, which ca n be used as fuel, reused for lower end products or resold to waste collectors for further processing, thus the financial investment in this system can pay off over a short period of time.
3. Maxi mum security against fire hazards: consummate electrical protection functions, complemented with an efficient Fire detect ion and Suppression system, leaving no fire hazards undetected and no open flame unquenched.
4. Modular structure, plus multi-power control, ensuring the proper performance of the whole system even if some of the power packs failed to work.
5. Ease of cleaning and maintenance: Filter cells are washable and can be easily accessible through the cell access door.
We also designed an ESP system especially for the PVC production line. It can perfectly solve the air pollution problem during the PVC production process. Meanwhile, the waste DOPI DEHP oil collected by the ESP would feature a comparatively high purity, thus can be put into other proper use, or to be sold to the waste oil collector for further processing , offsetting a substantial amount of initial cap ital and operational investment.
Take a 25m-long drying line of a PVC production line for example. We'd normally recommend an ESP with an airflow capacity of 1 600 0 m /h. If the product ion line keeps working for 24 hours a day and 330 days per year, and fume concentration is up to 450mg /m , then the amount of collected waste oil per day would be:
Q = C * V * h* n " 450*16000*24*10* 99% = 171kg.
