Description
Technical field
The present invention relates to the cooking fume remover field, is a kind of detection method and detection system of electrostatic oil fume purification utensil ability specifically.
Background technology
At present, living standards of the people improve constantly, and the catering trade is in fast development recent years, and a large amount of food and beverage enterprises occur in a large number.The restaurant is a large amount of oil smoke of unavoidable generation in the process of cooking.This oil smoke produces very big influence to enterprise around the food and beverage enterprise and resident's productive life.For this reason, environmental administration requires food and beverage enterprise to install and use cooking fume remover.
Use more and effect preferably cooking fume remover mainly be the electrostatic oil fume clarifier; Its principle of work is: the polarized area of clarifier polarizes to the elaioleucite in the oil smoke or is charged; Make it have electric charge, let the elaioleucite of being with point through having the pole plate of high pressure then, charged elaioleucite can be under effect of electric field; Shifted onto on the pole plate by electric field force, accomplish absorption and clean-up effect.This electrostatic oil fume clarifier also has problems: when the clarifier ability to work reaches capacity, need to clean the pole plate that is used for adsorption band point elaioleucite; Otherwise clarifier will lose detergent power.Because use the food and beverage enterprise of electrostatic cooking fume remover often not too to pay close attention to the purification utensil ability, so often cause the purification utensil ability to be lost, clarifier becomes ornaments.
For this reason, supervisory systemss such as environmental administration need a kind of effective means, are used to supervise food and beverage enterprise and descend in electrostatic oil fume clarifier cleanliness, and when detergent power was not enough, cleaning device pole plate was so that recover the clarifier ability to work.But because the complicated component of oil smoke own, the physicochemical characteristics of the elaioleucite of absorption is not easy to detect, so be difficult to produce the detergent power that highly effective method is used to detect the electrostatic oil fume clarifier.
A kind of method of indirect detection purification utensil ability is: through the weight change of inspection absorption pole plate, judge the weight change of the elaioleucite that the absorption pole plate has adsorbed, thereby judge the detergent power of clarifier indirectly.The shortcoming that this Indirect Detecting Method exists is: (1) accuracy of detection is not high, the weight of relative pole plate, and the weight ratio of the elaioleucite of absorption is less, and it is difficult to improve accuracy of detection; (2) be subject to disturb, owing to the condition restriction of erecting equipment, the influence of air-flow, the influence of other equipment of next door etc., and the adsorbability of oil smoke own, cause equipment malfunction etc., all can cause bigger influence, thereby cause test result inaccurate test result; (3) need transform existing equipment, perhaps require built-in this function of device fabrication producer, this will cause improvement cost bigger, promote comparatively difficulty.
The another kind of method that can directly detect the purification utensil ability is: the oil smoke concentration checkout equipment is installed in the exit through at clarifier, the clean-up performance of the oil smoke behind the inspection purification utensil, the detergent power of judgement clarifier.This through directly detecting the method for the clean-up performance that purifies the back oil smoke; Not enough below existing: the gas after (1) regular acquisition testing send special detection mechanism; Can more accurately calculate the cleanliness of the oil smoke after the purification; But it is cumbersome to operate, consuming time longer, does not have too big actual operation; (2) can detect the result after purifying through special online detection instrument is installed, this method speed is fast, can operate, and buys and new checkout equipment is installed but relate to, and enterprise and mechanism for monitoring are had high input.
In addition, also there be a kind of electromagnetic induction device and data acquisition/treating apparatus of passing through, judge that clarifier whether in the method for moving, excavates but do further function, thereby can not detect the detergent power of electrostatic oil fume clarifier.
