With the continuous development of social economy, the catering consumption mode is increasingly diversified and modernized, the catering industry has been growing at a high speed by two digits for 10 years continuously, and the catering industry in China will continue to keep the high-speed growth mode for five years in the future. Branding, scale, chain and cross-region catering operation are the future trend, popular catering operation will be continuously extended, special catering will be more prominent, and Chinese dinner catering status is more obvious. Data shows that the national catering income in 2018 achieves 42716 million yuan, the increase rate is 9.5 percent higher than that in the last year, the retail ratio of commodities is 0.6 percent higher, and the number of restaurants is close to 600 ten thousand. Meanwhile, Chinese cooking oil smoke is large in quantity and complex in components, contains a large amount of particulate matters and smoke VOCs (Volatile Organic Compounds), pollutes indoor air, is harmful to human health, and is an important precursor of air pollution. The data show that the analysis result of the PM2.5 source of large cities such as Beijing city and the like shows that: the contribution of the catering industry is about 4-15%. This proportion may even exceed the amount of vehicle emissions in certain areas. Along with the gathering of residents, the catering industry is a low-emission waste gas pollution source closest to the living environment, complaints account for about 15% of complaints of new houses on average, the waste catering pollution complaints in Beijing city in 2017 account for 22.9% of complaints of air pollution types, and the complaints of partial cities account for more than 50%. With the increasing attention of residents and countries, related laws and regulations and local standards are coming out in succession in recent years, and new requirements are continuously increasing on the oil fume purification treatment.
The production history of the Chinese oil fume purifier is very short, and the history of large-scale industrialized production is no more than fifteen years. In the middle of the 60's of the 20 th century, oil smoke purifiers began to be used in hong Kong, and early oil smoke purifiers and technologies mainly come from Japan, and simple ways such as mechanical grilles and water smoke carrying hoods were mainly adopted at that time. Until the middle of the 90 s of the 20 th century, in the relatively economically developed domestic areas, the traditional mechanical oil fume purifier cannot meet the purification requirement due to the environmental pressure, and the electrostatic oil fume purifier begins to enter the market at this time. In this case, the technology of the electrostatic oil fume purifier is very immature and is in a test stage, and the main technology of the electrostatic oil fume purifier is derived from the conventional industrial electrostatic purifier. The national GB18483-2001 'cooking fume emission standard' is officially issued in 2001, and the standard requires that all catering enterprises must be provided with a cooking fume purifier. The market prospect of oil smoke purification is obvious at a glance, and the mechanical oil smoke purifier aiming at large particle pollutants in oil smoke and the electrostatic oil smoke purification technology aiming at stable aerosol pollution components in the oil smoke in the gradually mature technologies temporarily account for the mainstream of the purifier market at present.
However, in the growing demand of the oil fume purifiers, a large number of purifier production enterprises emerge nationwide, wherein a group of small workshop type enterprises are not lack, low-quality products are sold at low price, and the operation and maintenance work of the purifiers is far behind the sales amount due to the intense price competition, so that the purifiers installed on the site are similar to the nominal one, and the purification treatment problem is also exposed undoubtedly, specifically as follows:

(2) The installed purifier does not operate normally: part oil smoke blowdown unit has been installed oil smoke clarification plant, and the enterprise does not reduce the operation cost, and is idle not opened or the intermittent type starts in daily operation, even deliberately damages the facility, leads to the oil smoke directly to discharge.
(3) The purifier cannot be cleaned regularly: although some oil fume pollution discharge units are provided with oil fume purification facilities, the oil fume pollution discharge units are not cleaned regularly or repaired under the damaged condition.
At present, the electrostatic purifier occupies more than 80% of the market, but the electrostatic purifier only has some simple operation parameter displays at the equipment end, whether the electrostatic purifier has faults or needs to be cleaned or not needs to be confirmed by professionals on site, the efficiency is very low, and the purification equipment is in a failure state gradually along with the loss of operation and maintenance work of the purification equipment without asking for help. Based on this, the utility model provides a pair of electrostatic clarifier on-line monitoring device utilizes data collection station to gather the operating signal of electrostatic clarifier, utilizes the monitoring host computer to confirm the running state of electrostatic clarifier according to operating signal, consequently the utility model provides an electrostatic clarifier can replace the manual work to patrol and examine, has reduced the on-the-spot manual work and has patrolled and examined the cost, can also effectively supervise the running state of electrostatic clarifier.
